This briefing is based on two propositions.

First, that gas security matters, because today in the UK gas plays a dominant role in the provision of energy services, accounting for almost 40% of total inland primary energy consumption in 2017. Thus, a short run failure of gas security would undoubtedly have significant political and economic consequences.

Second, that the current measure is far too narrow to offer a comprehensive assessment of UK gas security, particularly in a post-Brexit context. Discussions at the Gas Security Forum suggested that: the measure of gas security focuses only on infrastructure capacity and not supply (capacity does not equal flow); it fails to take account of the time-lag for gas delivery; it does not measure diversity or spare capacity; it ignores the impact of multiple asset failures; and, does not consider the costs associated with ensuring greater security.

It is in this context that this paper seeks to address the following questions:

• What are the constituent factors to consider in assessing gas security?
• What alternative measures exist?
• What potentially threatens gas security in the UK?
• What would a better approach to gas security look like?

The thinking behind this paper is that a more extensive approach to measuring UK gas security is needed to address the less dramatic challenges that face UK gas security, as well as the chance of managing a Black Swan event.

A review funded by HubNet and UKERC, and written by the University of Strathclyde's Damien Frame, Keith Bell and Stephen McArthur, argues that RD&D activity by Britains electricity distribution network operators has significantly revived; this revival is linked to Ofgem's 500m Low Carbon Network Fund investment.

The principal aims of this paper are to examine the range of reported unit costs for major generating technologies, show the range of estimates, explain where possible the reasons for the range, and show to what extent there is any clustering around central values. In addition, the paper explains the components of unit cost calculations and discussed what is, and is not, included in these calculations.

This working paper considers the risks and opportunities posed to UK heat sector businesses by a potential transformation towards a low-carbon heat system in the UK. It is an output from the Heat, Incumbency and Transformations (HIT) project which is part of the UK Energy Research Centre programme.

The HIT project is investigating the idea of incumbency, considering what the term means, how it is present in the UKs heat sector and what the implications of incumbency are for the UKs potential transformation from a high carbon heat system to a low-carbon heat system.

The previous working paper developed a working definition of incumbency (Loweset al., 2017). This working paper forms the second phase of the project, exploring who the incumbents are in the UK heat system and the implications of the potential transformation for incumbents.

This report, commissioned by the Aldersgate Group and co-authored with Vivid Economics, identifies out how the government can achieve a net zero target cost-effectively, in a way that enables the UK to capture competitive advantages.

The unique contribution of this report is to identify the lessons from successful and more rapid historical innovations and apply them to the challenge of meeting net zero emissions in the UK.

Achieving net zero emissions is likely to require accelerated innovation across research, demonstration and early deployment of low carbon technologies. Researchers analysed five international case studies of relatively rapid innovations to draw key lessons for government on the conditions needed to move from a typical multi-decadal cycle, to one that will deliver net zero emissions by mid-Century.

The case studies include:

• The deployment of the ATM network and cash cards across the UK;
• Roll out of a gas network and central heating in the UK;
• The development of wind turbines in Denmark and then the UK;
• Moving from late-stage adoption of steel technology in South Korea to being the world leading exporter; and
• The slower than expected development of commercial-scale CCUS to date across the world. 

The report also sets out which low carbon technologies are likely to have wider productivty and growth benefits in other industries for the UK. These include carbon capture, use and storage (CCUS); heating, ventilation and air conditioning (HVAC); wind energy; biofuels and batteries. These areas should be prioritised by the government’s innovation strategy going forwards.

• The UK needs innovation to meet its carbon targets and for this process to beeffective and rapid – with several critical components:market confidence, finance,public policy and thecapability to innovate
• Collaboration and shared understanding is required – involving interactions across science, business and government to facilitate knowledge transfer and learning – it is easier to achieve a transition with a shared understanding of the drivers of new low carbon energy technologies
• The slower the pace of energy innovation, the less time the UK will have to transition to a low carbon economy and the more expensive it will be to do so
• Successful innovation systems often involve open and iterative processes, which are complex. They depend on multiple interactions between different actors
• Policy interventions are required to drive innovation in energy and low carbon – business needs certainty so policy stability matters
• Industry and government should work together to set strategic priorities – low carbon markets are almost entirely driven by public policy but delivered by private sector firms
• Successful innovation in low carbon energy requires new technology capabilities, new markets, new business models together with appropriate changes to the regulatory framework

This workshop had several aims:

1. To increase understanding of the different approaches to ABM and their applicability to informing energy and other policy intervention design
2. To identify policy areas where ABM techniques could be usefully applied and to examine how they could be incorporated into the policy making process.
3. To develop joint research proposals aimed at relevant research funding bodies.
4. To develop relationships between key researchers in this emerging area.

• Planting 30 - 35 kha/yr of second generation crops (Miscanthus, Short Rotation Coppice (SRC) willow and Short Rotation Forestry (SRF)) would keep the UK on the trajectory to deliver a bioenergy sector of the scale needed to help cost-effectively decarbonise the UK energy system.
• Due to the seasonal nature of bioenergy crop planting, management and harvesting, the majority of job opportunities will be part-time, but are complimentary to the seasonal demands of other roles in the agricultural and forestry sectors, particularly arable farming. By 2032, a 30 kha/yr planting rate could create around 8,100 job opportunities in the busiest months (or 4,300 Full Time Equivalent (FTE) jobs when averaged across the year). By the 2050s, around 16,700 opportunities could be created during peak periods (9,100 FTE jobs across the year).
• The UK is not currently in a position to deliver a planting rate of 30 kha/yr - the total planted area of Miscanthus and SRC willow has remained at around 10 kha in recent years with a limited number of players in the market. Investment is needed in the production of plant breeding materials, including research into new establishment techniques to reduce costs. Investment is also needed in training and specialised equipment for planting and harvesting.
• As the UK prepares to leave the European Union, there is an opportunity to restructure farming support in a way which encourages the sustainable growth of the UK biomass sector. This could place a value on the wider environmental benefits growing second generation energy crops can make to the farming landscape.

• Respondents have consistently supported government-led action to tackle greenhouse gas emissions. In 2017, over half of respondents (58%) thought that the government should do more to reduce emissions, with only 6% believing that the government should reduce efforts to lower emissions.
• Support for producing bioenergy from both biomass and waste has been consistently strong across all three surveys with the highest levels of support recorded in the most recent survey. Across the three surveys between 72% and 77% of respondents supported the use of biomass, and 81-84% supported the use of waste for bioenergy production.
• Bioenergy is associated with several positive features. The ability to generate energy from waste has consistently been the positive feature most selected by respondents. The ETI’s broader analysis highlights the importance of using waste feedstocks effectively to deliver emissions savings. In order to help achieve this, the ETI is investing in a 1.5 MWe waste gasifi cation demonstration plant with syngas clean-up.
• In all three surveys, competition for land and having to import biomass because not enough is produced in the UK have been perceived by respondents as the main negative features of bioenergy. Our 2016 report explored these views in more detail and concluded that using a mix of imported and domestic feedstocks could be publically acceptable, such that the UK is not overly reliant on imports and can maintain at least current levels of food self-sufficiency
• The government has consistently been the most popular choice to lead the development of the bioenergy sector, but a greater number of respondents trust scientists/academics or experts in the field, independent consumer or industry watchdogs, and environmental interest groups to provide reliable information on the sector. This suggests it will be crucial for different groups to work together to increase awareness and understanding of bioenergy while developing the sector in the UK.

This note provides an overview and guide to a process of assessment being undertaken by the UK Energy Research Centre Technology and Policy Assessment function (TPA), with support from the Carbon Trust.

The UKERC has consulted widely on the topics that the TPA needs to consider. It has chosen its preliminary topics carefully, in consultation with stakeholders and in accordance with defined criteria. Intermittency – used herein as shorthand for a range of issues that relate to the costs and electricity system impacts of the intermittent electrical output from wind, solar and some other forms of grid connected renewable generation – has emerged as one of two initial TPA assessment topics.

The TPA will undertake meta-analysis of existing work in order to seek gaps in knowledge, examine different modelling assumptions, and consider how well different pieces of work fit together. The assessment will seek to make clear where and why differences arise in terms of models, assumptions, scenarios and interpretation of findings. It will identify research gaps and provide a clear statement of the nature of the questions that remain.

A key goal is to achieve high standards of rigour and transparency. We have therefore set up a process that is inspired by the evidence based approach to policy assessment undertaken in healthcare, education and social policy, but that is not bound to any narrowly defined method or techniques. The approach entails tight specification of the means by which we will consult stakeholders and solicit expert input, highly specified searching of the relevant literature, and clear and transparent criteria against which relevant findings will be assessed. It is described in the Review Protocol, below.

An introduction to the subject matter and description of assessment activities are provided in this scoping note and protocol.

The note is aimed at informed commentators and therefore takes some knowledge for granted – for example of terminology, recent literature and the principal concepts. Its focus is on why and where opinions differ, and the objective is to highlight questions and disagreements, but not answer or resolve either. A more general introduction to the subject is provided in the project scoping note and protocol.

Feedback and comment is invited on all of what follows, and in particular on the set of summary questions at the end of this note.

The remainder of this note covers the following topics:

• Identification of key issues
• Capacity values
• System balancing
• Allocating costs
• Framing questions

The energy system is highly complex and its future is uncertain due to unexpected changes and contrasting values. The complexity of the system may be defined by, for example, changing politics, technologies, finance and demographics. Under these conditions, decision-makers may struggle to confidently assess their future needs. However, decisions must be made so that organisational objectives are achieved, energy supply is secure and directives are met. For high-level decisions (e.g. strategic decisions reaching far into the future) it is unlikely that more time and better data will reduce uncertainty, and as a result, decisions must be made with existing information. Techniques like scenario analysis are useful for gathering this type of disparate information.

Deliberative techniques (e.g. scenario analysis) are used under conditions of high decision complexity and uncertainty. These techniques may interrogate multiple decision options under various future conditions, thus providing a first-step in understanding inherent risks and uncertainties. In this report we used scenario analysis to assess a set of risks under two plausible future energy scenarios. The studied scenarios included an energy system on a trajectory of development that did not deviate from its current projection (status quo) and a low carbon scenario whereby energy generation was largely provided by non-carbon (e.g. renewable) sources. Energy system experts were used to qualify the different risks and provide industrial insight.

The study analysed a suite of nineteen unique risks. These included political (international agreement, geopolitical issues, UK political issues), economic (project capital costs, investor trust in government, commodity pricing, electricity pricing), social (behavioural change, public perception, democratization of process), technical (rate of innovation vs implementation, energy supply chain, project risks, transport infrastructure), legal (end of life and stranded assets, pre/post operational governance, UK planning and licensing), and environmental (cumulative environmental factors, accidents and climactic events) issues.

The results of this study suggest that political and economic drivers pose the greatest risk, or barrier, to future energy system development. Though these two themes were perceived as being most risky, the character of the risks varied for each scenario. For example, political drivers (i.e. geopolitical) and the impact they may have on hydrocarbon prices posed the greatest risk to an energy system reliant on fossil fuels (i.e. status quo). This was in contrast toa low carbon scenario where the character of political risk (i.e. UK politics) focussed around long-term national policy-making, which in turn highlighted issues about investor confidence. Regardless the differences in character, experts perceived political consistency as being vital for improving confidence in their decision-making. Overall, experts consistently rated risks associated with a low carbon scenario higher than those for the status quo.

Our report provides a snapshot of current industrial thinking about the risks associated with different future pathways that the UK energy system may follow. In addition to identifying perceived risk priorities, this analysis also provides an indication of where gaps in knowledge and understanding about risk may exist. Strategies for addressing these gaps may include improved communication (e.g. between industry, government and academia) or targeted research. In either instance, the ultimate aim is to reduce uncertainty and improve conditions for long-term decision-making in the UK energy system.

This document is a report on the study conducted by the Joule Centre titled 'Aviation in the North West: Emissions, Economics and Organisational Flying'.

The international community recognises climate change as one of the greatest threats facing the social, environmental and economic well-being of human-kind. At a national level, the UK has demonstrated a clear international lead in responding to climate change by putting the need for and delivery of greenhouse gas emissions reductions on a statutory footing through the Climate Change Act 2008. This act introduced legally binding targets to achieve emission reductions in both the short and longer term. Furthermore, and unlike previous UK emission reduction policies, the Climate Change Act includes international aviation emissions explicitly in its 80% 2050 target and implicitly within the current budgets.

For the UK as a whole, then, there is a clear need to balance the cost and overall economic impact of delivering additional reductions in greenhouse gas emissions for these 'other' sectors versus the costs and economic impact of curbing growth in emissions from aviation.

The Tyndall Centre for Climate Change Research, funded by the Joule Centre for Energy Research, has analysed the emissions, economics and policy implications of the region's aviation industry. The objectives of the Tyndall Centre study are:

1. Introduction
2. Aviation and the North West
3. Estimating Regional Aviation Emissions
4. Developing Low Carbon Pathways for the North West
5. Economic impact of constraining aviation emissions growth
6. Organisational consumption: Understanding Flying for Work
7. Conclusions and Recommendations

• Trade-offs and co-benefits need to be actively managed if multiple environmental objectives are to be achieved and the low carbon transition is to enhance the natural ecosystems that are essential to prosperity and well-being. UKERCs research on environmental goals informs the answer to Q1.
• Energy efficiency and heat system retrofit in buildings offers an immediate triple-win in terms of economic stimulus, societal benefits and environmental goals. A strong long-term economic case can also be made to boost investment in all of those areas where the UK will need to build infrastructure and capacity in order to meet decarbonisation objectives. UKERC has examined the evidence on green jobs. We explore this in more detail in our answer to Q2.
• There are already skills gaps in the sectors relevant to energy efficiency retrofit and it is important to invest in addressing these, as we explain in the answer to Q3.
• Further action is needed to strengthen the industrial strategy. Ambition needs to go well beyond the aim to decarbonise one (or even all) of the UKs industrial clusters. Decarbonising all of industry will require research, development and demonstration support for breakthrough technologies and wider low-carbon infrastructure; market creation for products made via low carbon production processes; and promotion of resource efficiency and circular economy approaches. UKERC has published a number of reports highlighting where further action is needed, as detailed in Q4.
• Our research shows widespread low carbon ambition in local authorities but significant challenges in converting this to action. To change this, government could establish a new policy mandate for net zero carbon localities, institutionalise local net zero carbon planning and implementation through a new statutory power and devolved resources, and invest in local authority net zero teams. Q5 reviews a range of evidence on the role of local government.

UKERC have submitted a response to the BEIS call for evidence on the future for small-scale low-carbon generation. This consultation sought to identify the role that small-scale low-carbon generation can play in the UK shift to clean growth by further understanding:

• The challenges and opportunities from small-scale low-carbon generation in contributing to government's objectives for clean, secure, affordable and flexible power; and
• The role for government and the private sector in overcoming these challenges and realising these opportunities.

In our submission we responded to the individual points raised in the call, drawing on two streams of work undertaken as part of the UKERC research programme. The first stream concerns community energy, drawing primarily on data from the UKERC Financing Community Energy project. This project has collected and analysed data from a number of sources:

• Quantitative data gathered as part of a UK-wide survey of community energy finance and business models. This dataset covers 145 community energy projects run by 48 different community energy organisations.
• Qualitative data on community energy organisations' suggestions for changes in public policy and industry practice, and their plans for the future, gathered as part of the same UK-wide survey.
• Further qualitative data on community energy organisations' views on pathways to future decentralised energy business models, gathered at workshops held as part of the Manchester Mayor's Green Summit process, and the Community Energy England annual conference 2018.
• A wide range of other data and literature, including access to the dataset collected for Community Energy England's 2017 State of the Sector Survey, covering 220 community energy organisations in England, Wales and Northern Ireland.

The second stream draws on a number of recent UKERC publications on electricity systems and networks :

• Developing low carbon networks for a low-carbon future
• Security of electricity supply in a low-carbon Britain
• The Costs and Impacts of Intermittency
• Delivering a highly distributed electricity system: Technical, regulatory and policy challenges.

What policies and other factors have driven change/transformation in heat delivery technologies, fuels and infrastructure? The Technology and Policy Assessment (TPA) Theme of UKERC have published a scoping note outlining their ongoing investigation into this topic.

Part of the Energy-PIECES project, this report was developed during a secondment at the Energy Savings Trust.

This paper explores the sensitivity of energy system decarbonisation pathways to the role of afforestation and reduced energy demands as a means to lessen reliance on carbon dioxide removal. 

Large uncertainties surround the viability of carbon dioxide removal

The stringency of climate targets set out in the Paris Agreement has placed strong emphasis on the role of carbon dioxide removal (CDR) over this century. However, there are large uncertainties around the technical and economic viability and the sustainability of large-scale CDR options. These uncertainties have prompted further consideration of the role of bioenergy in decarbonisation pathways and the potential land-use trade-offs between energy crops and afforestation. The interest in afforestation is motivated by its potential as an alternative to large-scale bioenergy with carbon capture and storage (BECCS), with its arguably lower risk supply chains, and multiple co-benefits. Furthermore, doubt over the viability of large-scale CDR has prompted a renewed examination of the extent to which their need can be offset by lowering energy demands.

Testing the impacts of reduced demands and afforestation

A global optimisation model (TIAM-UCL) was used to examine decarbonisation pathways for the global energy system. Based on core assumptions, where energy demands follow business as usual trends and degraded land is used for energy crops, the model was unable to find a solution for a 1.5°C target. Over the period 2020-2100, the carbon budget of GtCO₂ is exceeded by 332 GtCO₂.

Scenarios where also run to examine how the least-cost decarbonisation pathway changes if i) energy demands are significantly reduced, or ii) degraded land is used for large-scale afforestation instead of energy crops. Each option on its own reduced the CO₂ budget exceedance but both were required to allow the model to meet the 1.5°C target.

Impacts on the energy system

Under the 2°C target, afforestation reduced the reliance on BECCS by 60%. Under the 1.5°C target, the system still used all of the biomass available, as the target is so ambitious. When the energy demands were lower, the effect of afforestation on biomass use was dependent on the climate target. Under the 2°C target, less biomass was used across all economic sectors, whereas under the stringent 1.5°C target, all the available wood and crop biomass was exploited, but its use shifted away from the production of liquid fuels towards use in power generation.

Lowering energy service demands had a larger effect on the energy mix than large-scale afforestation. This is because demands are lowered differently across the sectors according to their economic drivers. However, afforestation had a bigger impact on the marginal cost of climate change mitigation, as it substantially decreases the scale and pace of change required by the energy system, especially in the 2°C case.

Given its key role, afforestation should be considered more in deep decarbonisation scenarios, as should lower demand scenarios.

Lowering energy demand and introducing large-scale afforestation both present significant challenges and opportunities. Further work should focus on factors affecting the carbon sequestration potential of afforestation, along with an interdisciplinary research agenda on the scope for large scale energy demand reduction. Research on the social, technical and economic factors that affect the potential for converting abandoned agricultural land to energy crops or new forest would be beneficial. An interdisciplinary research agenda is needed that brings together techno-economic modelling and qualitative scenario development with research on the social change that could lead to large reductions in energy demand

This Meeting Report gives an overview of the 'Breaking the Deadlock in Climate�Change Communication' event, which was held on�12 March 2014 at the Church House Conference Centre.

This briefing paper examines how renewables in Scotland are shaped by decisions taken by the Scottish Government, the UK Government and the EU. Drawing on interviews with stakeholders, it explores the potential impact of Brexit on Scottish renewables.

Brexit has the potential to disrupt this relatively supportive policy environment in three ways in regulatory and policy frameworks governing renewable energy; access to EU funding streams; and trade in energy and related goods and services.

Our briefing identifies varying levels of concern among key stakeholders in Scotland. Many expect policy continuity, irrespective of the future UK-EU relationship. There is more concern about access to research and project funding, and future research and development collaboration, especially for more innovative renewable technologies. The UK will become a third country forthe purposes of EU funding streams, able to participate, but not lead on renewables projects, and there is scepticism about whether lost EU funding streams will be replaced at domestic levels.

While there is no real risk of being unable to access European markets even in a No-Deal Brexit scenario, trade in both energy and related products and services could become more difficult and more expensive affecting both the import of specialist labour and kit from the EU and the export of knowledge-based services. Scotlands attractiveness for inward investment may also be affected.

This Working Paper presents key findings from research conducted within the Energy and Environment theme since 2009, when the second phase of UKERC activity began. Research within this theme has investigated the impacts associated with a range of marine and land-based energy production and greenhouse gas (GHG) mitigation technologies including bioenergy, wind, tidal, gas, nuclear and carbon capture and storage (CCS). The carbon and water footprints of these technologies have been investigated as have their social, economic and environmental impacts and their impacts on terrestrial and marine ecosystem services.

This briefing note summarises initial findings from qualitative research undertaken as part of a major project investigating public values, attitudes and views on whole energy system change.

A key objective of the project is to identify degrees of public acceptability relating to various aspects of whole energy system transformation and the trade-offs inherent in such transitions. This research has relevance as a research evidence base for informing development of future energy systems, as well as for understanding processes of and potential obstacles to delivery of such transitions.

The Faraday Institution and the Department for International Development (DfID) commissioned consultants Vivid Economics to perform a rapid market and technology assessment of storage in weak and off-grid contexts in developing countries, to which this Insight refers.

This report explores ways of enhancing the resilience of the UK energy system to withstand external shocks and examines how such measures interact with those designed to reduce carbon dioxide (CO2) emissions. The concept of resilience is explored and a set of indicators is developed to define quantitatively the characteristics of a resilient energy system. In the report we systematically test the response of the UK energy system under different scenarios to hypothetical shocks. These are all assumed to involve the loss of gas infrastructure. We then assess mitigating measures which can help to reduce the impact of these shocks and test their cost effectiveness using an insurance analogy.

The development of a comprehensive industrial strategy for the UK is long overdue. The strategy is an opportunity to bring much needed coherence to economic and industrial policy, and to ensure that it works in tandem with the governments other policies and plans. It is particularly important that the strategy underpins the UKs transition towards a cleaner, low carbon economy. This will only be achieved if it is fully compatible with the Climate Change Act, and is integrated with the forthcoming Emissions Reduction Plan.

The Green Paper includes a welcome confirmation of the governments commitment to reducing greenhouse emissions to meet statutory targets, and to do so whilst meeting other important energy policy goals. Unlike previous statements of energy policy, we are pleased to see that the Green Paper adds a fourth policy goal alongside the familiar trilemmaof emissions r

We welcome the idea of offering more policy support to SMEs to enable the uptake of energy efficiency opportunities, to the benefit of their enterprises, the economy as a whole and the environment. Researchers have previously argued that there is not enough policy focus on SMEs (Banks et al, 2012, Hampton and Fawcett, 2017) and this consultation was valuable as part of a wider process of policy development.

This response covers general issues about design of policy for energy efficiency improvement in SMEs, and offers specific evidence on Option 2: a business energy efficiency obligation.

• Nearly 20 years of climate change policy has failed to reduce greenhouse gas (GHG) emissions linked to
  economic activity in the UK.
• Although the UK has met its Kyoto obligations, this has been achieved largely by outsourcing production and
  relying on importing consumer products from abroad to meet growing consumer demand. As UK consumer
  demand has continued to grow, so have the GHG emissions embedded in imported goods.
• If the UK is to measure its overall contribution to changes in global GHG emissions, consumer emission
  accounting offers a sound method for attributing GHG emissions.
• Increased transfer of low-carbon technologies to producer countries, even when technology transfer does not
  form part of any international GHG emissions reduction agreement, will help those countries to reduce their
  emissions and thereby contribute to a true global reduction.
• “Framework conditions” to encourage sustainable consumption might involve government intervention in areas
  such as prices, providing infrastructure for a sustainable lifestyle, and public engagement.

This meeting follows on from the UK Energy Research Centre annual assembly and brings speakers from leading national positions, who can provide perspectives on success, failure, and future pathways. Will the UK be a leader in climate stabilisation? Or is that moment about to pass?

The focus is on CCS ( carbon capture and storage). This is suite of technologies to capture CO2 at power stations and other concentrated sources, liquefy and transport the CO2, and inject into rock pores deep below ground. The Intergovernmental Panel on Climate Change produced a special report on CCS in 2005, where a worldwide analysis showed that CCS could halve the increase of CO2 emissions by 2100 especially in coal using countries. The UK has claim to a world-class opportunity for CCS, utilising reservoirs deep beneath the North Sea. Will technology, industry, and Government enable thisopportuni

The proposal is that our carbon intensive goods and services should contribute to lower carbon emissions and be redefined in light of climate change. A carbon label has the potential to be an important part of this redefinition, but should be built on a successful consensus about what a carbon label should do, how and how this is best delivered. This briefing paper provides a broad review of evidence and poses pertinent questions surrounding the development of carbon labelling.

This report is split up into a series of questions, each of which includes relevant research findings, key issues and questions and implications of these for further work or labelling. They are highly interactive, as a decision on one has considerable influence on other factors. This report is accompanied by an appendix that contains more in-depth explanations and reviews of pertinent studies, papers an

This UKERC Meeting Place seminar, co-sponsored by the Sustainable Development Commission and the Department for Food, Environment and Rural Affairs, aimed to achieve three outcomes:

• a consensus on what carbon neutrality means, its validity as a concept, and whether there are different definitions which might apply to operations, plans and policies;
• a consensus on the use of carbon offsetting, if and when it is justified, and what constitutes a viable and sustainable carbon offset;
• a consensus on what steps need to be taken, by the UK Government, the Devolved Administrations and/or the private sector, to ensure that commitments and pledges on carbon neutrality (including the use of carbon offsets) are applied in a way which is robust and compatible with the UKs commitment to sustainable development.

The event set out to engage a multi-di

Britain used to be an energy powerhouse. We built technologies that brought jobs and prosperity across the country. We have a once in a generation chance to build on that prosperity and growth, but only if we double down on our advantages. If we delay, or fail to seize the available opportunities, other countries will win the race for these industries of the future. Clean energy is that future and a perfect fit for the UK's strengths.

The UK has major growth opportunities in Clean Energy Industries. We are a coastal nation, a scientific and innovation superpower, with strengths in high-value manufacturing and a skilled energy workforce to match. With our world-leading renewable energy deployment, and deep capital markets, Britain is the natural home for Clean Energy Industries. We can deliver investment in manufacturing and deployment that will have significant spillover benefits for innovation, services, and skills across the country, leveraging the clean energy transition to turbocharge growth.

Clean energy investors are clear that they want to grow in the UK and to invest billions here, but they cannot do this on their own. They need certainty, they need stability, they need a partner to take the first step with them in developing new technologies, and they need an incentive to expand supply chains. This is our plan to secure that growth, to back those Clean Energy Industries and unlock billions more in investment. To break down barriers to projects, to invest alongside industry where necessary, to ensure we create good jobs, to incentivise companies to build it in Britain.

This is the global economic opportunity of our time, and in an uncertain world, the Government's Missions to Kickstart Economic Growth and make the UK a Clean Energy Superpower are sending a clear message that we are unwavering in our commitment to these industries and to energy security. The net zero economy is already growing three times faster than the wider UK economy and we have seen over £40 billion of private investment in clean energy announced since July. Our Clean Industry Bonus smashed expectations, with £544 million for offshore wind developers to prioritise investment in regions that need it most, leveraging billions more in private investment, including in traditional oil and gas communities, ex-industrial areas, ports, and coastal towns.

Delivering Clean Power by 2030 will protect the economy and billpayers from the rollercoaster of fossil fuel prices, the cause of half of recessions since 1970.4 By harnessing the potential of AI, automation and advanced technologies we can optimise how energy is generated and consumed. The resulting modern, affordable, and secure energy system is fundamental to building a stronger and more productive economy. The UK will build an energy system that will bring down bills for households and businesses for good, bringing certainty, stability, and growth.

Growing our Clean Energy Industries and boosting domestic supply chains is fundamental to supporting wider industry to decarbonise. Growing our Clean Energy Industries and boosting domestic supply chains is fundamental to supporting wider industry to decarbonise. Foundational industries such as steel, chemicals, critical minerals, composites and other materials such as glass, provide critical inputs to enable growth in Clean Energy Industries.

The clean energy transition is the defining economic opportunity of the twenty-first century and the UK is uniquely positioned to lead it. The government's Plan for Change set out our ambitious mission to make Britain a clean energy superpower, which will kickstart economic growth and break down the barriers to opportunity as we create a new generation of good jobs across every corner of the country to deliver energy security.

Someone is going to win the global race for the clean energy jobs of the future and we are determined that it should be the UK. The job opportunities on offer are huge, with roles available across a range of skill levels and occupations, from plumbers to production managers, engineers to electricians, and technicians to welders. This presents a significant opportunity to revitalise our industrial heartlands and ensure that our existing home-grown energy workforce can move flexibly into good clean energy roles.

Clean energy is already providing good jobs to hundreds of thousands of people across the UK. Jobs in Wind, Nuclear, and Electricity Networks all advertise average salaries of over £50,000, compared to the UK average of £37,000. For young people, these jobs can offer higher levels of pay across occupations, with entry-level 'green' roles commanding a 23% average pay premium in around 60% of occupations. These jobs also provide the security of a rapidly-growing sector, as new and emerging green jobs are less likely to be automated and have had more resilience in demand than the wider jobs market in recent years.

However, we know there is more to be done. While the clean energy workforce is growing rapidly in the UK, by around 8% and 10% per year in 2022 and 2023 respectively, other countries have far more jobs per capita. For example, in 2023 Germany had almost 3 times as many renewable energy jobs per capita as the UK; Sweden and Denmark almost 4 and 5 times as many respectively. Across the economy, industry investment in skills has been falling in recent years with evidence suggesting significant underinvestment in the UK compared to our European peers.

The government's recent significant programme of investment in clean energy, alongside the Clean Energy Industries Sector Plan and this Jobs Plan, shows our firm commitment to ensuring Britain leads the world in the clean energy transition and creates the conditions needed for industry to accelerate investments in the skills system.

This annex describes the experimental approach taken to assessing the growth required in the clean energy workforce from a 2023 baseline to 2030, where opportunities are likely to be located, and the types of occupations likely to be in high demand and relatively more difficult to fill.

Clean energy technologies encompass power generation, transmission and distribution, greenhouse gas removals, clean heat, and energy efficiency. The full list of sub-sectors is provided in Table 1 below. Clean energy jobs are measured as the number of jobs that are supported by the deployment and operation of clean energy technologies and their supply chains. This analysis covers both direct and indirect jobs, these employment categories can be defined as:

Induced jobs are excluded from this analysis; employment resulting from the spending of wages by workers in direct and indirect employment, leading to increased demand in other sectors.

This analysis does not measure net additional jobs across the economy. Much of the increase in workforce across clean energy sectors will involve workers who have transitioned from other sectors or will displace high carbon energy jobs; however, these effects are not accounted for as the evidence is not available. The analysis also does not capture replacement demand - i.e., the workers required to replace workers that leave the clean energy workforce.

There is inherent uncertainty in estimating the size of the 2030 clean energy workforce. The future size and geographic spread of the clean energy workforce will be dependent on delivery and final location of the pipeline of projects out to 2030, the ability to recruit into the sector, cost assumptions, any assumptions made about the ability of UK businesses to export overseas, and the validity of the assumptions made around the workers required to deploy a particular amount of technology. These estimates do not represent precise predictions; they are indicative of the orders of magnitude the clean energy workforce will need to increase by 2030 to meet demand in UK clean energy sectors and their supply chains (where possible, both domestic and global demand has been considered - see Table 1 for details).

The aim was to examine the specific triggers for changes in patterns of understanding and attitude – and the conditions under which these lead to changes in behaviour. New and innovative methodologies were developed, including the preparation of authentic news broadcasts to present possible future outcomes of climate change and problems with energy security constraint. The results show how beliefs held by audiences can be affected when they receive new information. The conditions under which people believe or reject different arguments are at the heart of the study.

Priorities for the Energy Cost Review

This week, the government's long awaited Clean Growth Strategy will be published. Like many, we will be looking for details of how UK emissions will continue to be reduced to meet the 4^th and 5^th carbon budgets. In particular, the Strategy will need to explain how a range of increasingly significant policy gaps will be addressed.

The Strategy is likely to be closely followed by the conclusions of the Review of Energy Costs, led by Professor Dieter Helm. Ahead of the Strategy's publication, we are publishing a briefing paper that covers four key issues that are central to the terms of reference of the Review of Energy Costs - and to the Clean Growth Strategy itself.

Our starting point is that the primary issue is the cost of energy bills for consumers, rather than only the unit price of energy. It is therefore important to focus on measures that can reduce the quantity of energy required for a given level of service as well as trends that could help to reduce or moderate prices. In line with the terms of reference, our briefing paper focuses on electricity costs since UK electricity prices are higher up the European league table than those for gas.

Energy efficiency

The role that energy efficiency can play in reducing electricity bills needs to be fully addressed. Significant progress in this area remains to be made; savings of up to 10% can be achieved through well designed standards and investment programmes, and a recent UKERC report highlighted that a 25% reduction in household energy demand is possible through cost effective measures. There is a clear rationale for government intervention, to drive energy efficiency and address the policy gap left behind by the failure of the Green Deal. The case is even clearer when considering the additional economic and social benefits that energy efficiency brings.

Innovation and technology cost reduction

The creation of new markets help drive technology cost reductions, as does patient government support. Offshore wind is a case in point - achieving much lower than expected prices in the recent Contracts for Difference auctions. If these projects are delivered, this will place offshore wind amongst the cheapest new sources of electricity generation in the UK.

Policy change is required to drive further innovation, yet with investor confidence low, this needs to build on existing policy instruments. A case has been made for moving low carbon technologies into a single competitive auction. However this technology neutral approach favours technologies close to market, failing those which are less developed. Complex technologies such as carbon capture and storage, which have significant potential but high capital expenditure and associated risk, could require a state-led approach to investment, allowing for competition to drive prices down.

A systems approach is required

The review's terms of reference clearly state that a systems approach is required. The consideration of technologies within this perspective is imperative, as is developing energy policy within this context. This is particularly relevant for electricity, where a range of mechanisms and markets are used to balance supply and demand in real time.

System flexibility is key to keeping costs down. The cost of integrating renewables into the grid vary widely, with future cost of integrating intermittent power sources, depending upon the availability of cost effective system flexibility. Incentivising flexibility and reforms to the capacity market will be required to facilitate this, and as the proportion of renewables increases, government will need to decide how to account for system costs including those surrounding intermittency.

Research, development and demonstration

Innovation is an important driver for reducing costs and bringing technologies to market. However this non-linear process exists with multiple feedbacks between development, demonstration and deployment. Effectiveness is further dependent on incentives for demonstration and market creation, and UKERC research has shown that innovation in the energy sector tends to take three to four decades from early stage R&D to significant commercial deployment.

Analysis has been undertaken by government to establish this evidence base, yet too often this has focused on discrete technologies, with less attention paid to system innovation. It is this system innovation which will be key to the low carbon transition, alongside effective evaluation, to learn and disseminate lessons.

Eye catching initiatives such as the Faraday Challenge for storage are welcome, as is the UK pledge - as part of Mission Innovation - to double clean energy R&D spending between 2015-2020. Whilst a step in the right direction, when considering the scale of the challenge posed by climate change, many argue that government support for innovation at a greater scale is required.

We welcome the opportunity to comment on the findings of the Cost of Energy Review, conducted by Professor Dieter Helm. In our response, we address most of the questions set out in the Call for Evidence from BEIS. Before turning to these specific questions, we have three general observations about the Review and the Call for Evidence.

First, whilst the review title focuses on the cost of energy, this is misleading. The terms of reference and the Review report make it clear that the main focus is electricity rather than energy in general.

This distinction is important since the data shows significant differences in the position of UK electricity and gas costs when compared to costs in other countries. There are also differences between relative costs for households and relative costs for business energy consumers. UK electricity prices are higher up the European league table than prices for gas. Electricity prices for energy intensive industries in the UK are particularly high.

Our second comment is that there are important distinctions between prices, costs and bills. Whilst much of the debate focuses on prices, the costs of energy for consumers also depends on their energy consumption. Therefore, it is also important to consider energy efficiency of buildings, appliances and industrial processes since these are a key determinant of costs.

Our third comment is that costs need to be considered for the electricity system as a whole. Whilst the separate questions in the Call for Evidence about generation, networks and retail supply are understandable, costs to consumers partly depend on interactions between these components of the electricity system. This compartmentalised approach to the evidence base could mean that some of these systemic interactions are missed.

We welcome the re-assertion of key policy objectives and the commitment to a whole system approach described in the strategy. In our response we highlight a number of key areas that need to be addressed including the need for geographical specificity, and a hierarchy of objectives along with the introduction of low and stable prices as one of these objectives.

• Services to domestic, commercial and industrial users
• Heat demand is highly variable (2010)
• 2030 generating mix?
• Multiple competing options
• Intertwined opportunities
• Complex socio-technical system
• Consumer satisfaction - machine learning

This is the second in a series of reports arising from UKERCs Energy 2050 project. The report considers the prospects for accelerated development of a range of emerging low carbon energy supply technologies and the possible impact of this acceleration on decarbonisation of the UK energy system. The technologies analysed here include a number of renewables (wind power, marine energy, solar PV and bioenergy) and other emerging low carbon technologies (advanced designs of nuclear power, carbon capture and storage (CCS) and hydrogen / fuel cells). The report presents a set of scenarios devised by UKERC to illustrate how accelerated development of these technologies could contribute to decarbonisation of the UK energy system from now to 2050. The results suggest that technology acceleration could have a major influence on UK decarbonisation pathways, especially in the longer term.

The European Commission talks the talk on energy, but can it walk the walk? In this UKERC working paper, Antony Froggatt (Chatham House) and Amelia Hadfield (Canterbury Christ Church University) look at the challenge of moving from ambition to delivery in the EU's flagship Energy Union plan.

Incumbency is frequently considered as a barrier to the transformation of unsustainable socio-technical systems such as energy systems. However, despite wide use of the term, 'incumbency' has never been fully or adequately defined within the sustainable transitions literature. This working paper considers the use and meaning of the term incumbency in relation to sustainable transformations, specifically in relation to the UK's heat system. It takes ideas of incumbency from other disciplines including economics, politics and innovation. Synthesising these literatures, the paper proposes a number of characteristics of incumbency. Finally we propose a definition of incumbency in relation to sustainability transformations, which suggests that incumbents are actors already present in a specific socio-technical system, who are likely to be involved with unsustainable practices, and who possess the capacity to affect system change.

UKERCs response provides commentary and analysis on many of the wide range of topics encompassed in the consultation. This includes the overall vision and objectives, case for change, the evaluation criteria defined by BEIS, locational pricing and local markets, lessons from other countries, changes to wholesale markets and incentives for low carbon generation, flexibility and capacity.

Our response provides detailed and evidence-based analysis on each of these complex topics, drawing on UKERC research and wider outputs. We highlight some of the complex trade-offs involved and argue for a cautious and gradualist approach that builds on the progress already made in some areas.

This document is the executive summary for the project titled 'Producing a Time Series of Input-Output Tables and Embedded Carbon Dioxide Emissions for the UK by Using a MRIO Data Optimisation System'.

This report describes work and results from the project 'Development of an Embedded Carbon Emissions Indicator', undertaken by the Stockholm Environment Institute and the University of Sydney on behalf of Defra (Project Ref.: EV02033). The work is a follow-up of a previous project where the most appropriate approach to constructing a robust account of impacts of trade and thus overall consumption in a headline indicator for Sustainable Development was identified. The present work describes the implementation of such a model.

The project aim was to develop and implement an initial data and model framework (called "UK-MRIO 1") for the flexible adaptation of national input-output and environmental databases for use in a multi-region environmental input-output model in the future, thus setting the basis for detailed multi-country analyses of environmental impacts associated with UK trade flows. This aim was not only achieved but actually exceeded in that a fully functional MRIO model with four regions (UK + three world regions) was assembled and a time series of balanced input-output data and embedded CO2 emissions was produced on the full 123 sector level.

The current model is a major step towards a fully fledged multi-region input-output model featuring multidirectional trade of a substantial number of UK trading partners. UK-MRIO 1 is already the most detailed and comprehensive modelling approach for the estimation of CO2 emissions embedded in UK trade with high relevance for national and international environmental policy-making. The model can be used to produce a range of outputs, for example more detailed results for industry sectors, foreign economies, or other pollutants.

This document is the final report for the project titled 'Producing a Time Series of Input-Output Tables and Embedded Carbon Dioxide Emissions for the UK by Using a MRIO Data Optimisation System'.

For this stage of the project (UK-MRIO 1), the aim was to develop and implement an initial, relatively small, data and model framework that is easily expandable without major adaptations. A data optimisation procedure is to allow the flexible adaptation of national input-output and environmental databases for use in a multi-region environmental input-output model in the future. Thus the work was to set the basis for multi-country analyses of environmental impacts associated with UK trade flows, including detailed accounts of embedded in trade flows to and from the UK over a period of time.

In order to achieve this aim, initial data estimates have been made, data constraints have been defined and specific optimisation algorithms have been developed and implemented. As a tangible outcome of the current project we have constructed a time series of annual input-output tables for the UK from 1992 to 2004 by using a modified RAS7 procedure for balancing (referred to as 'Conflicting RAS' or 'CRAS'). These tables are similar to the "Analytical IO Tables 1995" published by ONS, including symmetric input-output tables (SIOT) for domestic transactions and imports for each year from 1992 to 2004 (see Appendix C: Data Sources and Data Preparation on page 41). In addition to the original project aim, we have also calculated a time series of direct and indirect carbon dioxide emissions associated with UK economic activities, in particular emissions that are embedded in imports to and exports from the UK.

The in-depth analysis presented in this report focuses on four key areas of the economy, highlighting how they may need to change to remain competitive and meet future carbon targets.

• Heat: All approaches for heat decarbonisation are potentially disruptive, with policymakers favouring those that are less disruptive to consumers. Since it is unlikely that rapid deployment of low carbon heating will be driven by consumers or the energy industry, significant policy and governance interventions will be needed to drive the sustainable heat transformation.
• Transport: Following the Road to Zero pathway for road transport is unlikely to be disruptive, but it is not enough to meet our climate change targets. The stricter targets for phasing out conventional vehicles that will be required will lead to some disruption. Vehicle manufacturers, the maintenance and repair sector and the Treasury may all feel the strain.
• Electricity: Strategies of the Big 6 energy companies have changed considerably in recent years, with varying degrees of disruption to their traditional business model. It remains to be seen whether they will be able to continue to adapt to rapid change or be overtaken by new entrants.
• Construction: To deliver low-carbon building performance will require disruptive changes to the way the construction sector operates. With new-build accounting for less than 1% of the total stock, major reductions in energy demand will need to come through retrofit of existing buildings.

The report identifies how policy makersplan for disruptions to existing systems. With the right tools and with a flexible and adaptive approach to policy implementation, decision makers can better respondto unexpected consequences and ensure delivery of key policy objectives.

There is an increasing sense of urgency about the global energy system transition. For many observers an urgent energy transition is also a necessarily disruptive one, in that it is only by radically remaking energy systems that an accelerated transition to low carbon and sustainable energy can be achieved.

Closer to home, there has been substantial progress in some parts of the energy system in the decade since the passing of the UK and Scottish Climate Change Acts. Other areas have shown little sign of change, and the transition ahead may well be more disruptive and intrusive than that seen so far. At the same time, there is also an emerging counter-narrative: that repurposing our existing energy assets (physical and social) offers the best and quickest transition path, since there is insufficient time to disrupt and remake.

Attending energy events and keeping up-to-date with emerging evidence can instil a sense of different experts talking past each other. For those involved in whole systems energy research, and working at the research-policy interface, this can be deeply frustrating. To help address this, UKERC - working with ClimateXChange (CXC), Scotland's Centre of Expertise on Climate Change - has spent two years analysing disruption and continuity in the UK energy system.

As part of that work, we surveyed around 130 experts and stakeholders about disruption and continuity-led change in the UK energy transition. The experts were mostly UK based researchers working on 'whole systems' research projects, but also included policymakers, advisory bodies, think tanks, businesses (old and new) and civil society organisations. This report presents the results of this survey work.

Overview

A series of energy policy changes announced since the May election have led to concerns about increasing political risk faced by prospective investors in the UK energy system (ECCC 2015). It has also been suggested that policy needs to be ‘reset’, with less technology-specific intervention and increased resources for longer term research into new technologies (Helm 2015). This paper draws on a large body of analysis from UK Energy Research Centre (UKERC) and Imperial College.

The paper argues that a ‘reset’ approach is unnecessary, will create delays to investment, increase political risks, and hence costs to consumers. Simply put, the government already has the levers it needs to encourage investment in a secure and lower carbon system. Policy can be made more effective by providing investors with greater clarity and a longer term perspective, using the policy framework that is already in place. Auctions for Contracts for Difference (CfDs) have already brought forward significant reductions in the prices paid to low carbon generators. CfDs could be moved progressively to a technology neutral basis, combined with price caps to bear down further on costs.

The paper discusses the infrastructure implications of new sources of energy and notes that government will need to balance the benefits of technology neutral CfD auctions against the need to develop strategic infrastructure in a timely fashion. It also discusses the impacts of variable renewables and explains that whilst it is important for system costs to be allocated cost effectively this does not mean that variable generators should be obliged to self-balance and invest in dedicated back up.

The paper also explains that whilst greater investment in innovation would be welcome, forthcoming research shows the timescales associated with invention, demonstration and deployment of technology are long. Whilst improvements to technologies are hugely important, the emergence of entirely new technologies remains very uncertain. Support for innovation should not be premised on wishful thinking about silver bullet technologies. Many of the technologies we need to decarbonise already exist and have done so for several decades. The challenge is to drive costs down and encourage network innovation to better suit new sources of power.

Finally, the paper argues that whilst more effective carbon pricing would bring many benefits it is not a sufficient condition for significant energy system change. Regulation iv UK Energy Research Centre of emissions from existing coal fired power stations after 2025 would aid investor clarity and improve the prospects for investment in both low carbon and gas-fired generation.

The following points emerged as the most important:

• There needs to be a link between physical modelling of devices and biological models or data sets
• The impact on sea-mammals, birds and fish should be urgently addressed
• Any Environmental Monitoring should be in 3 stages: before, during and after device installation, and each stage should ideally take place over at least 12 months to take into account seasonal effects. Time is not on the device developer’s side
• There is very little data available on the movement of birds and sea mammals, and nothing can be ascertained about their interactions with devices until in situ data/observations are made (e.g. at EMEC)
• Continuous monitoring is very expensive, time consuming and difficult. At present there is little funding available and what funding there is, is very difficult to release
• The boundaries of acceptability have to be defined to assist developers.
• There should be an agreed environmental monitoring programme that all developers are encouraged to follow at all sites (bearing in mind particular sensitivities of site)
• It is not clear what parameters should be measured and what is the best technology available for an environmental monitoring programme.
• A monitoring programme should concentrate on possible showstoppers for marine developers

• ETI consumer research highlights issues to address if the UK is to change how it heats the vast majority of buildings
• Today fewer than 4% have low carbon heating and 90% prefer gas central heating»Location constrains the heating solutions available to each building and existing buildings have their own constraints

• Improve low carbon heating designs so they tackle common problems and enhance home life
• Simplify installations so they are more convenient
• Enhance heating control so people can value what they spend, get what they want from low carbon systems and factor heat into renovation decisions

This report therefore considers what a 2030 world would look like for PiV ( plug-in electric vehicles) purchase and use to be at the levels foreseen in typical scenarios, where it would be possible to end the sale of pure fossil fuel vehicles by 2040 or earlier. It discusses the challenge - how to design and operate the energy system to make that possible. This report discusses three key questions: The nature of the driver experience and the levels of service that could be provided by innovative use of modern internet technologies and infrastructure.

The kinds of public and private charging infrastructure that will be required and what this might mean for charging points in different locations, including the network upgrades required to support them. The integration and operation of the whole system including charging management, the effective carbon intensity of the added electricity load, and the impact on networks and the economics of generation.

The report highlights these key points:

Energy has been a central feature of the EU since inception as the European Coal and Steel Community (ECSC) in the 1950s. A mainstay of successive policies has been to introduce ‘singularity’ in to the sphere of energy at different scales – for example, from a narrow central pooling of physical resources, as with the ECSC, to much broader attempts at introducing a liberalised single market place for gas and electricity, and proposals for a single gas buyer mechanism under the 2015 Energy Union framework. These moves were typically internal responses to external events, such as the Arab oil embargoes or geopolitical tension between Russia and eastern European countries. To achieve the goal of a single internal energy market policies have sought to remove or reduce the friction placed on cross-border trade, governance and regulation of energy by often contradictory and conflicting national policies of member states. This has taken the form of specific and targeted pieces of legislation aimed at technical harmonisation, as well as wide-reaching sets of policies to overhaul entire sectors and governance and regulatory practice across all member states.

A recently published working paper written by Joseph Dutton of the University of Exeter Energy Policy Group as part of the Energy systems at multiple scales programme sets out the path along which EU energy policy has moved since the initial creation of the organisation in the 1950s, detailing the principle documents and legislation upon which the current and proposed policies were constructed.

This insight was first published in November 2019, with minor updates made in May 2021.

This document sets out a response of the UK Energy Research Centre (UKERC) to the Department of Energy and Climate Changes (DECC) consultation Electricity Demand Reduction.

In our response to the consultation on electricity market reform (EMR) we noted the potential importance of demand reduction and demand side response in achieving the Governments goals for the electricity sector of security, emissions reduction and reasonable cost.

All our responses are based on evidence from research by UK academic researchers independent of commercial or other vested interest. One particular focus of the response is on the option of premium payments (otherwise known as energy saving feed-in tariffs). UKERC supported research (Eyre, 2013) is the first peer reviewed academic literature on this topic in the world. We believe that an approach along these linesis consistent with addressing a market bias against energy saving that would otherwise be introduced by EMR proposals in their current form. We begin the response with four key concerns about the evidence base used in the consultation document and its supporting literature. We then respond to some specific questions identified in the consultation document itself.

The paper first discusses estimates of the levelised costs of selected technologies and the corresponding rates of return under alternative assumptions as to prices. It then shows how such estimates can be refined to allow for the variability of demand, changes in plant dispatching schedules, storage and so forth. Next it considers the effects of environmental policies and innovation on costs and the rate of return. Finally it considers the issues posed by uncertainty and risks. By beginning with the simple cases of levelised costs and average returns, and then by gradually peeling away assumptions, the aim is to gradually reveal the fundamentally different perspective that arises when the rate of return becomes the focus of investment.

This paper considers GB electricity market and network regulatory arrangements in the context of transitioning to a low carbon electricity system. By considering some of the primary features of a low carbon electricity system and building on themes raised by a previous UKERC Supply Theme paper (Baker, 2009), the paper attempts to identify what characteristics an appropriate market and regulatory framework would need to posses. The paper goes on to consider how existing market arrangements perform in these areas and the possible need for change.

The aim of the paper is to contribute to the debate on energy market reform that is now underway. Currently, discussion seems to be focussing primarily on how to ensure adequate investment in low carbon and, in the medium term, conventional generation to meet the UKs climate change and security of supply goals. Delivering the necessary generation capacity is clearly crucial and by reviewing some of the mechanisms that could be used to encourage investment, this paper attempts to contribute in this area. However, the paper also addresses other areas where reform may be required but that have, to date, received less attention; issues such as arrangements to ensure efficient dispatch and energy balancing, efficient mechanisms to deal with network congestion and measures necessary to facilitate demand side participation.

The approach taken by the paper is incremental in nature, focussing on how current market arrangements may need to develop in the coming years, rather than proposing radical change. It is likely that successfully decarbonising the electricity sector may ultimately require a fundamentally different market design and that change, particularly in relation to low-carbon investment, may be requiredsooner rather than later. However, the transition to a low carbon electricity system will be gradual and arguably best served by incremental change in response to demonstrated need.

This meeting of independent experts addressed institutional arrangements for implementing UK Electricity Market Reform (EMR). It was convened jointly by the UK Energy Research Centre (UKERC) and the Imperial College Centre for Energy Policy and Technology (ICEPT). Institutional issues are closely tied to arrangements for a proposed Capacity Mechanism. Discussions at the workshop reflected this link.

The meeting considered both the general shape of the Electricity Market Reform (EMR) package and the four specific elements proposed in the Department for Energy and Climate Change (DECC) and HM Treasury (HMT) consultations. This summary covers first the generic aspects and then, more briefly, the four specific elements.

The ETI Natural Hazards Project is an initiative funded by the Energy Technologies Institute and delivered by EDF Energy, the Met Office and Mott Macdonald.

The project has produced a set of technical volumes summarising the state of the art on natural hazard characterisation for a variety of natural hazards. These are supported by a set of case studies. Each case study focuses on the application of the methodology and data outlined in the named technical volumes.

This document is a brochure for the launch event of this project titled Enabling Resilient UK Energy Infrastructure: Natural Hazard Characterisation Technical Volumes and Case Studies. This document discusses the context, importance, relevance, and outcomes of the project, along with additional locations for additional information.

The project has led to the development of a set of twelve technical volumes and case studies (found here), covering:

• An introduction to the technical volumes and case studies,
• Extreme High and Low Air Temperature,
• Extreme Wind,
• Extreme Precipitation,
• River Flooding,
• Coastal Flooding,
• Seismic, Volcanic and Geological Hazards,
• Hail,
• Lightning,
• Space Weather,
• Marine Biological Fouling,
• Hazard Combinations.

The aims of the technical volumes and case studies are to:

• Assist in the design of new infrastructure to ensure robustness to natural hazards now and into the future with climate change.
• Ensure that current infrastructure is adequately protected against natural hazards, in particular those emerging hazards researched as part of this project (e.g. space weather, hail, lightning).
• Inform investment decisions for new infrastructure projects as well as assisting with re-investment decisions to support life extension.
• Improve current operational procedures across the energy industry.
• Lead to better preparedness and response time during extreme event.

The purpose of this project is to identify, capture and communicate current relevant good practice when it comes to undertaking environmental risk analysis within the energy industry. This is done by providing access to well-structured and clearly documented good practice which can help avoid the use of outdated methods that could lead to the inaccurate specification of risk, resulting in inadequate or overly conservative infrastructure design. It is the absence of accessible and well-structured good practice that led to the Energy Technologies Institute's commissioning of its Natural Hazards Project.

The UK Government has been seeking views on bringing forward the end to the sale of new petrol, diesel and hybrid cars and vans from 2040 to 2035, or earlier if a faster transition appears feasible. In this joint UKERC/CREDS consultation response we provide views on the following aspects:

• the phase out date,
• the definition of what should be phased out,
• barriers to achieving the above proposals,
• the impact of these ambitions on different sectors of industry and society, and
• what measures are required by government and others to achieve the earlier phase out date.

A phase out date of 2035 or earlier is sensible yet it might not be enough. Our research, recently published in the journal Energy Policy, has found that neither existing transport policies nor the pledge to bring forward the phase out date for the sale of new fossil fuel vehicles by 2035 or 2040 are sufficient to hit carbon reduction targets, or make the early gains needed to stay within a Paris compliant carbon budget for cars and vans.

Our research has shown that deeper and earlier reductions in carbon emissions and local air pollution would be achieved by a more ambitious, but largely non-disruptive change to a 2030 phase out that includes all fossil fuel vehicles. This would include all vehicles with an internal combustion engine, whether self-charging or not. However, only the earlier phase outs combined with lower demand for mobility and a clear and phased market transformation approach aimed at phasing out the highest-emitting vehicleswould make significant contributions to an emissions pathway that is both Paris compliant and meets legislated carbon budgets and urban air quality limits.

The proposed policy will involve high levels of coordination, intention and buy-in by policy makers, business and wider civil society. By far the biggest barrier to change will be the incumbent industries the original equipment manufacturers (OEMs). They have a well-known track record of pushing back against EU vehicle regulations on the grounds of cost. In the case of electric powertrains, this push back is evident, with added resistance on the base of restricted supply chains and time to alter production processes. We suggest this is all the more reason to publish and implement a market transformation strategy now so that early wins which do not rely on supply chains or large transformations to the production line can mitigate against any later genuine supply-side constraints. Such a clear policy steer from the UK government is needed in order to ensure that UK consumers have more choice of cars than they may otherwise get if the OEMs restrict their sales of the most efficient vehicles into the UK market once out of the EU regulatory regime.

UKERC research into various phase-out policies has looked at how disruptive they would be for key stakeholders of the transport-energy system, and how much coordination would be needed to achieve the policy goals. This research has shown that in the Road-to-Zero ICE phase out by 2040 the main actors of the road transport and energy system are unlikely to undergo disruptive change. This is due to the relatively slow and limited evolution of the fleet towards unconventional low carbon fuels, the continuation of fuel duty revenue streams well into the 2040s and little additional reductions in energy demand and air pollutant emissions.

However, in the earlier (2030) and stricter (in what constitutes an ultra-low carbon vehicle) phase-outs we can expect some disruption for technology providers, industry and business in particular vehicle manufacturers, global production networks, the maintenance and repair sector as well as the oil and gas industry. There will also be localised impacts (some potentially disruptive) on electricity distribution networks and companies, even with smart charging.

Ending the sale of new petrol, diesel and hybrid cars and vans earlier, coupled with the electrification of road transport should form a key part of long term decarbonisation policy, but it is not a panacea. First, an earlier phase out date of 2030 implies we have 10 years to plan for and implement a transition away from fossil-fuel ICE cars and vans. As we discussed in our response, our research suggests that this is achievable without significant disruption to the transport-energy system, but it needs to be linked to accelerated investment in charging networks, battery development and deployment, increased market availability of zero-emission vehicles, and equivalent-value support by the Government to level the playing field with the incumbents. Second, our research has shown multiple times that further and earlier policy measures that impact the transport-energy system are needed, including a clear and phased market transformation approach that targets high-emitting vehicles, access bans in urban areas, and dynamic road pricing that could fund an order of magnitude increase in investment in sustainable transport modes.

We support bringing the phase-outdate forward and urge it to be earlier than 2035 and include phasing out any non-zero tailpipe vehicles using a market transformation approach. We strongly believe Government has a crucial role to play in leading the way to decarbonise transport, going well beyond the proposed policy change of bringing forward the end to the sale of new petrol, diesel and hybrid cars and vans from 2040 to 2035 or earlier.

The workshop presentations and the ensuing discussion clearly underlined the UK potential for community energy initiatives. There are in the region of 500 community energy projects currently in the UK, demonstrating a wide range of technologies and approaches. However, although these projects will generate a considerable amount of kilowatts, it is equally important to recognise other roles that they may play. The contribution of projects to, for example, combating social exclusion or increasing public understanding of renewable energy technologies may be as important as power generation or energy conservation.

This report is one of a series of working papers in the UKERC Energy 2050 project series. It investigated the role of pro-environmental lifestyle change for the UK energy system to 2050. We make two assumptions, both of which seem obvious when stated, but are frequently forgotten or ignored in energy futures work. The first is that the behaviour of energy users is not fixed, but rather the outcome of developments in society, and that these are uncertain with the level of uncertainty increasing over time. The second is that any policy framework that seeks to deliver major changes in the energy system, such as an 80% reduction in CO2 emissions, will be the outcome of a political process in which civil society, i.e. energy users in other roles, will play a key role.

We have used an innovative methodology to combine the strengths of detailed end use models (UK Domestic Carbon Model and UK Transport Carbon Model, both developed at the ECI) and a cost-optimisation model of the whole UK energy system (MARKAL Elastic Demand, developed at UCL).

Research for the UK Energy Research Centre’s Technology and Policy Assessment (TPA) function shows the importance of increased policy support for energy efficiency programmes, after a strategic review found savings in the region of 10% for well designed and implemented programmes. While multiple policies and programmes have been implemented in the past to encourage improvements in household efficiency, both in the UK and globally, the robustness and accuracy of programme evaluations have been called into question.

The authors carried out a systematic review of the evidence base of peer-reviewed evaluation programmes, drawn from conference papers and 20 different journals, in order to find out what works and where the gaps are, and to inform future programme design.

Welcome to the Energy Materials Availability Handbook (EMAH), a brief guide to some of the materials that are critical components in low carbon energy technologies. In recent years concern has grown regarding the availability of a host of materials critical to the development and manufacturing of low carbon technologies.

In this handbook we examine 10 materials or material groups, presenting the pertinent facts regarding their production, resources, and other issues surrounding their availability. Three pages of summary are devoted to each material or material group. A how to use guide is provided on the following pages.

Policy goals to transition national energy systems to meet decarbonisation and security goals must contend with multiple overlapping uncertainties. These uncertainties are pervasive through the complex nature of the system, and exist in a strategic policy area where the impact of investment decisions have long term consequences. Uncertainty also lies in the tools and approaches used, increasing the challenges of informing robust decision making. Energy system studies in the UK have tended not to address uncertainty in a systematic manner, relying on simple scenario or sensitivity analysis. This paper utilises an innovative energy system model, ESME, which characterises multiple uncertainties via probability distributions and propagates these uncertainties to explore trade-offs in cost effective energy transition scenarios. A global sensitivity analysis is then undertaken to explore t

This report aims to support informed debate about the amount of biomass that might be available globally for energy, taking account of sustainability concerns. It uses a systematic review methodology to identify and discuss estimates of the global potential for biomass that have been published over the last 20 years. The assumptions both technical and ethical that lie behind these are exposed and their influence on calculations of biomass potential described.

The report does not seek to determine what an acceptable level of biomass production might be. What it does is reveal how different levels of deployment necessitate assumptions that could have far reaching consequences for global agriculture, forestry and land use; ranging from a negligible impact to a radical reconfiguration of current practice. The report also examines the insights the literature provides into the interactions between biomass production, conventional agriculture, land use, and forestry.

This document is a summary for the project titled 'Energy management in tourism: development of a comprehensive carbon footprint methodology and toolset.'

The project provides a stepping stone towards the development of a tool that will allow members of an important sector of the NW economy to monitor and manage their energy use. It will also help the NW to be at the forefront of essential environmental auditing and impact assessment methodologies. The project has expanded the NW's research capability in the field of energy consumption monitoring and brought researchers from three disciplines together (economics, environmental science and statistics). The application is being developed for all organisations working in the tourist industry in the NW, but will start with demonstrations in Blackpool and Cumbria. It is intended the application will calculate greenhouse gas footprints, which can be partitioned into their component energy sources and highlight major contributory activities. The tool will allow the user to see how their carbon footprint responds to: increasing their expenditure within certain industry sectors (e.g. food whole sellers, transport, construction); changing the nature of their expenditure within each sector.

This project used an existing prototype footprinting model and managed to demonstrate its economic robustness and realism. From this a tool was developed and then tested. The effectiveness of the tool was demonstrated by working with a hotel in the Lake District where the outputs have changed its purchasing strategy. A further £300,000 funding has been obtained (£200,000 ESRC and £100,000 NWDA) to continue developing the model and to create a system for widespread release.

The review is structured around the central research question: To what extent are energy and ecosystem scenarios consistent and comparable? The research will be conducted using a Rapid Evidence Assessment (REA) approach. More details on the project and the approach can be found in the scoping note.

This meeting report summarises discussions at a conference UKERC co-hosted in March 2016 to identify future challenges in energy systems research.

• a description of the policy imperative which supports local area energy planning;
• an assessment of how this fits inwith energy planning already being undertaken by various local authorities and energy network operators across the UK;
• an explanation of the steps to be taken in adopting a whole system approach to local area energy planning outlining how local areas can follow an approach which reflects local circumstances to achieve decarbonisation goals, clean growth and other local drivers such as energy security and affordability, reflecting government advice.

The aim of the workshop was to bring together academics and practitioners from different disciplines and backgrounds in order to ultimately inform more effective approaches to public communication of, and engagement with, climate change and energy reduction. The overarching question to be addressed by the workshop was, What can empirical and theoretical studies of communication and behaviour change tell us about how we might move towards a more climate-friendly (low-carbon, climate resilient) society?. More specifically the workshop objectives were to: share cutting-edge research and practice; foster learning across disciplines and contexts; identify gaps in understanding; form new interdisciplinary contacts and networks; consider and generate new insights; stimulate novel collaborations; provide the contents for a book and a workshop report that would beuseful for academics, practit

The aim of the workshop was to bring together academics and practitioners from different disciplines and backgrounds in order to ultimately inform more effective approaches to public communication of, and engagement with, climate change and energy reduction. The overarching question to be addressed by the workshop was, “What can empirical and theoretical studies of communication and behaviour change tell us about how we might move towards a more ‘climate-friendly’ (low-carbon, climate resilient) society?”. More specifically the workshop objectives were to: share cutting-edge research and practice; foster learning across disciplines and contexts; identify gaps in understanding; form new interdisciplinary contacts and networks; consider and generate new insights; stimulate novel collaborations; provide the contents for a book and a workshop report that would be useful for academics, practitioners and policy-makers. Central to the workshop were three sessions relating to the overarching question: models, messages and media. These sessions involved 10 minute presentations from each of three presenters and a 10 minute response from an invited discussant.

This working paper analyses the environmental sustainability of four electricity production systems that include carbon dioxide capture and storage (CCS):

• Pulverised coal (PC)
• Pulverised coal with oxyfuel combustion (PCOC)
• Natural gas combined cycle (NGCC), and
• Integrated gasification combined cycle (IGCC)

The analysis is based largely on a review of relevant Life Cycle Assessments (LCAs). Thus it considers the environmental sustainability of the entire electricity generation chain from fuel extraction through electricity generation and CO2capture to CO2 storage.

There is increasing scientific evidence that natural systems are now at a level of stress globally that could have profound negative effects on human societies worldwide. In order to avoid these effects, one, or a number of technological transitions will need to take place through transforming processes of eco-innovation, which have complex political, institutional and cultural, in addition to technological and economic, dimensions. Measurement systems need to be devised that can assess to what extent eco-innovation is taking place. Environmental and eco-innovation have already led in a number of European countries to the establishment of substantial eco-industries, but, because of the general absence of environmental considerations in markets, these industries are very largely the result of environmental public policies, the nature and effectiveness of which have now been assessed through a number of reviews and case studies. The paper concludes that such policies will need to become much more stringent if eco-innovation is to drive an adequately far-reaching technological transition to resolve pressing environmental challenges. Crucial in the political economy of this change will be that eco-industries, supported by public opinion, are able to counter the resistance of established industries which will lose out from the transition, in a reformed global context where international treaties and co-operation prevent the relocation of environmentally destructive industries and encourage their transformation.

The UK Energy Research Centre welcomes this opportunity to provide input to the Stern Review on the Economics of Climate Change. 

The Centre was established in 2004 following a recommendation from the 2002 review of energy initiated by Sir David King, the UK Government’s Chief Scientific Advisor. It is funded by three research councils: the Engineering and Physical Sciences Research Council (EPSRC), the Natural Environment Research Council (NERC) and the Economic and Social Research Council (ESRC). We take a co-ordinated and collaborative approach to national and international energy research, and through our own interdisciplinary research activities, we intend to provide the knowledge needed to work towards a sustainable energy system and realise UK energy policy goals.

We are a distributed Centre operated by a consortium of eight universities and research institutions. Our work is relevant to items 1 and 4 of the Review Terms of Reference, i.e.

• The implications for energy demand and emissions of the prospects for economic growth over the coming decades, including the composition and energy intensity of growth in developed and developing countries; and
• The impact and effectiveness of national and international policies and arrangements in reducing net emissions in a cost-effective way and promoting a dynamic, equitable and sustainable global economy, including distributional effects and impacts on incentives for investment in cleaner technologies

Four of our research themes are undertaking research relevant to the Review. These are:

• Energy Systems and Modelling, operated by the Policy Studies Institute
• Demand Reduction, operated by the Environmental Change Institute, Oxford University
• Energy Infrastructure and supply, operated by the University of Manchester and Warwick Business School
• Future Sources of Energy, operated by the University of Edinburgh

• What is the ETI?
• Our energy system evolves around our choices
• Change happens fast
• Why do we need to balance?
• The tools at our disposal
• How much storage is needed?
• Vector Flexibility
• Demand Flexibility

• Create new energy systems, adapt existing ones and integrate them together
• Users define the energy system’s evolution, not the other way around
• Understand the implications of different scenarios so that we are prepared to evolve

Social Value is a rising policy agenda in the UK, formalised in legislation by the Public Services (Social Value) Act 2012. It refers to social, economic and environmental benefits whose value is not captured in financial flows. Whilst multiple tools and methodologies are available to measure Social Value, there is little consensus on which method is best to use in different contexts. This report reviews options and considers how best to measure Social Value in the context of major energy infrastructure projects such as HPC.

The report finds that value is highly contingent and subjective, and that what is valuable is not always tangible. It therefore emphasises the importance of qualitative measures of Social Value alongside quantitative data or monetary estimates, recognising the limits of assigning financial values to some types of outcome. It also stresses the importance of involving stakeholders to find out what matters to them and what they most value.

This report provides a brief review of how risks can be incorporated into investment decisions, and how financial analysis needs to go beyond an assessment of levelised costs in order to adequately represent the different sources of risk that a new power plant investment will face in competitive markets.

Concern about fairness in the retail energy market is clear from media headlines and the passing of legislation to impose a wide price cap in the retail energy market in 2018. Fairness in Retail Energy Markets? Evidence from the UK provides extensive evidence from a range of disciplines to inform this important debate. This report does notattempt to define what constitutes fair or unfair, since this ultimately rests in the eye of the beholder. Nevertheless, its message is clear: development of the retail energy market in the UK can only be understood by recognising the political economy around questions of distribution and fairness.

A multi-disciplinary perspective

The publication reports research conducted at the Centre for Competition Policy, University of East Anglia, as part of the UK Energy Research Centres programme. The research is multi-disciplinary, drawing together researchers from a range of disciplines: economists, legal scholars, human geographers and a policy analyst. This range of specialisms provides a rare opportunity to consider fairness and retail energy markets in the round. The research team is both unusually broad and academically independent. The reports five main chapters present findings from different disciplines and methodologies to stimulate consideration of evidence which is rarely encountered together. In assembling this evidence the researchers are grateful to our partners Broadland Housing Association, Cornwall Energy and Ofgem, as well as to the Parliamentary Archive and all our interviewees.

The report presents findings under five broad themes: (i) how long-term outcomes contextualise the retail energy markets political salience; (ii) how distributional objectives feed into institutions; (iii) the multi-faceted nature of engagement with energy; (iv) the detailed experiences of those at risk of FP; and (v) how data/statistics can be improved.

Key issues highlighted

Together the evidence raises fundamental issues for the future governance of the market. The traditional focus of economics on efficiency has never claimed that markets are effective tools for delivering equitable outcomes, and the traditional framework of pure economic regulation is challenged by the focus on fairness. Can the market ever escape political intervention when energy prices rise substantially? This question is particularly relevant when key affordability support policies the Winter Fuel Payment and the initial Fuel Poverty Strategy were introduced as energy was approaching its mostaffordable level over a 30-year time horizon.

Energys political salience has meant that the independence of the market regulator, Ofgem, has evolved in a way not originally envisioned. Government has increased the number and complexity of Ofgems statutory duties. The resulting ambiguity regarding how to prioritise the regulators different duties has led to increased government-regulator communication and the potential for government to exert pressure on the regulator through less formal channels.

We present evidence indicating that there are problems with implementing the main frame used to address energy fairness in the UK, namely fuel poverty. We suggest that the approach to analysing fuel poverty, and the associated policymaking, would benefit from a change of direction, towards a focus on the directly observable real-world phenomenawhich underpin this complex problem, rather than on the official fuel poverty statistics. Such an approach would help to recognise that energy efficiency interventions are unlikely to solve all the energy affordability challenges facing households.

Energy saving feed-in tariffs (ESFITs) are a relatively new concept and are designed to use the same principles as Feed in Tariffs for renewable energy (REFITs).�They offer a promising way of improving electricity efficiency and reducing electricity demand, thereby decreasing carbon emissions.

The Electricity Market Reform proposals which form part of the 2012 Energy Bill provide a bias towards investment in new supply that could be addressed using ESFITs.�

In the context of EMR, ESFITs offer a means of delivering decarbonisation with a lower impact on consumer bills.

Because ESFITs do not rely on energy companies, they would provide incentives for innovation in project delivery in a much wider range of actors including householders, community groups, local authorities and small businesses.

The concept of ESFITs is simple, but there are policy design issues that still need to be addressed.

Commencing in 2016, the Financing Community Energy project provides a comprehensive quantitative and qualitative analysis of the role of finance in the evolution of the UK community energy sector. This report presents the final of our four case studies of UK community energy organisations, exploring how these organisations have sought to finance their projects against a backdrop of diminishing government support for grassroots sustainable development.

Established in 2013, Brighton and Hove Energy Services (BHESCo) primary focus was to develop both renewable energy and energy efficiency projects, whilst also ensuring people have equal access to energy. BHESCo is rather unlike our other community energy case studies in that it operates very much like an Energy Services Company (ESCo), where they accept some degree of responsibility to provide the energy service that its customers ultimately desire (e.g. lighting, ambient temperature), rather than the straightforward supply of heat or electricity.

This report presents a case study of Edinburgh Community Solar Cooperative, exploring how it financed the project against a backdrop of diminishing government support for grassroots sustainable development.

This report presents the first of four case studies of UK community energy organisations, exploring how these organisations have sought to finance their projects against a backdrop of diminishing government support for grassroots sustainable development.

Edinburgh Community Solar Cooperative (ECSC) is a Community Benefit Society (BenCom). Its objectives are a combination of environmental and social, with an explicit focus on reducing emissions, alleviating fuel poverty, improving energy security and promoting sustainable development education.

ECSC quickly settled on renewable power generation as a means of delivering this combination of environmental andsocial value. Today it operates 1.4 MW of solar PV panels on the roofs of 24 council-owned properties in Edinburgh, including schools, leisure centres and community halls.

Commencing in 2016, the Financing Community Energy project provides a comprehensive quantitative and qualitative analysis of the role of finance in the evolution of the UK community energy sector. This report presents the second of four case studies of UK community energy organisations, exploring how these organisations have sought to finance their projects against a backdrop of diminishing government support for grassroots sustainable development.

Green Energy Mull (GEM) is a Community Benefit Company (BenCom) that owns and operates Garmony Hydro; a 400 kW run-of-the-river hydro scheme on the island of Mull, off the west coast of Scotland.

Commencing in 2016, the Financing Community Energy project provides a comprehensive quantitative and qualitative analysis of the role of finance in the evolution of the UK community energy sector. This report presents the third of four case studies of UK community energy organisations, exploring how these organisations have sought to finance their projects against a backdrop of diminishing government support for grassroots sustainable development.

Gwent Energy (Wales) was formed in 2009 to deliver environmental benefit and cost savings to its local community. It aims to help local consumers save money on their energy bills through a combination of renewable energy, efficiency, storage and electric vehicle charging interventions, whilst simultaneously generating a surplus to fund local community initiatives.

To recover the cost of energy policies which support the transition towards a low carbon energy system, levies are applied to household and business energy bills. This briefing note focuses on the levies applied to households.

Household energy policy costs

Energy policy costs are applied to household electricity and gas bills, equating to 132, or 13% of the average energy bill in 2016. This research highlights how low-income households are hit hardest by the current arrangements as the poorest households spend 10% of their income on heat and power in their homes, whereas the richest households only spend 3%, so any increase in prices hits the poor disproportionately.

Energy service demands in the UK

Household electricity and gas use represents only 12% of total final UK energy use. Total energy use includes all the energy used to provide househ

Natural gas plays a critical role in the UK’s energy system, providing twice as much energy as electricity, thus the secure and affordable supply of natural gas is an essential element of UK energy security and a key objective of Government policy. The starting proposition for this report is that Brexit is coming at a time when there are already major challenges to the UK’s future gas security.

This report deploys two aspects of previous UKERC research on UK gas security: first, a supply chain approach to assessing UK gas security; and second, a whole systems approach that places current and future gas demand within the context of the decarbonisation of the UK’s energy system. This is because there are key uncertainties in the wider system that have important implications for future gas demand. It is in this context that the Brexit decision has created additional uncertainty at a time when the UK energy sector needs to make critical investment decisions. In the current situation we can conceive of a ‘Brexit Interregnum’ whereby important decisions and policies are delayed because of the demands of the Brexit negotiations.

This report has three objectives:

• To identify the key challenges facing the UK’s natural gas market;
• To understand the role that EU policies and institutions currently play in the operations of the UK’s natural gas market; and,
• To identify the potential impact of Brexit and the key issues that should be addressed in a post-Brexit ‘UK Gas Security Strategy.’

The report also focuses on the broadly ‘physical’ factors that may restrict the rate at which conventional oil can be produced, including the production profile of individual fields and the distribution of resources between different sizes of field. While these are invariably mediated by economic, technical and political factors, the extent to which increased investment can overcome these physical constraints is contested. Global oil supply is also influenced by a much wider range of economic, political and geopolitical factors (e.g. resource nationalism) and several of these may pose a significant challenge to energy security, even in the absence of ‘below-ground’ constraints. What is disputed, however, is whether physical depletion is also likely to constrain global production in the near-term, even if economic and political conditions prove more favourable. In practice, these ‘above ground’ and ‘below ground’ risks are interdependent and difficult to separate. Nevertheless, this report focuses primarily on the latter since they are the focus of the peak oil debate.

The report does not investigate the potential consequences of supply shortages or the feasibility of different approaches to mitigating such shortages, although both are priorities for future research.

The meeting brought together around 100 energy professionals from academia, business, the public sector, and nongovernmental organisations to discuss governance challenges and solutions for achieving a sustainable, secure, and affordable British energy system. The organisers approached this from a wide range of expertise including policy, law, regulation, energy provision, energy efficiency and behavioural change. The day began with a plenary in which four speakers introduced the topic. This was followed by breakout sessions to cover six themes:

• Technologies and investment
• Behaviour and lifestyles
• Local governance
• Institutions, decision making, and legitimacy
• International governance issues
• Business, new entrants, and new practices

During a closing plenary five speakers reflected on the key messages fromthe meeting.

At present, Governments commitment stands in sharp contrast with its inaction on heat decarbonisation to date. Under pressure to progress this agenda, Government has charged the Clean Heat Directorate with the task of outlining the process for determining the UK’s long-term heat policy framework, to be published in the Roadmap for policy on heat decarbonisation in the summer of 2020 (BEIS, 2017). This report, resulting from one of six EPSRC-funded secondments, is designed to support early thinking on the roadmap by answering the research question: How can Transitions research informs the roadmap for governing the UKs heating transition?

Delivered as part of the Energy-PIECES project, this report was developed during a secondment with BEIS.

This report was produced by the UK Energy Research Centre’s (UKERC) Technology and Policy Assessment (TPA) function.

The primary objective of the TPA, reflected in this report, is to provide a thorough review of the current state of knowledge. New research, such as modelling or primary data gathering may be carried out when essential. It also aims to explain its findings in a way that is accessible to non-technical readers and is useful to policymakers.

• Current HEMS market in the UK is dominated by relatively simple products with slim margins
• The real long term aim is to establish and own the customer relationship in the home; simple HEMS products are the gateway device to a connected-home
• The connected-home market is most likely to be led by ambitious and well-funded technology players
• Telcos are also well-placed to move into the space with bundled offerings but no sign as yet
• Of the Big 6, currently only British Gas is demonstrating the ambition to drive development of the HEMS market
• Advanced ESCo offers are likely to take longer to, or may never, develop in the market
• Smart home development likely to develop later as an evolution from earlier automation
• The big prize for ETI is in developing the Advanced ESCo proposition where there are 3 primary opportunities identified
  • Right-sizing of heating solutions
  • Optimisation of time of use and demand response benefits via local storage
  • Arbitrage-driven operation of hybrid heat pumps
• Preparing for a non-energy led scenario may also be sensible to consider, especially in the shorter term

This response is largely based on research carried out within the UKERC project: The Geopolitical Economy of Global Gas Security and Governance: Implications for the UK. It also draws on UKERC’s energy system modeling research which has explored the changes that are necessary to meet the UK’s climate change targets.

Local Authorities role in the energy transition and working with their citizens in doing so, has been recognised as crucial to paving transition paths. Material collated within this report is intended to better inform Energy Cities and its partners, Local Authorities and Municipalities, civil society groups and others interested in how citizens can be supported and encouraged to participate in energy system developments as a part of the energy transition. The findings in this report are therefore intended to directly help Local Authorities across Europe in implementing more participative approaches to their governance practices in energy systems.

Delivered as part of the Energy-PIECES project, this report was developed during a secondment with Energy Cities.

To what extent are energy and ecosystem scenarios consistent and comparable? A new working paper from the TPA Theme of UKERC suggests that energy and ecosystem service scenarios are broadly consistent, with climate change representing a unifying narrative.

1. Construction of a set of socio-technical scenarios of air conditioning uptake,
2. Dynamic building simulation to estimate half hourly power consumption of air conditioning in archetypal single buildings,
3. Addition of air conditioning demand to existing prediction of 2050 national grid demand (National Grid Two Degrees 2050 scenario).

This document is the final report for the project titled 'Impact of the Climate Change Programme on Industrial Carbon Dioxide Emissions'.

The UK has a legally binding target under the Kyoto Protocol to reduce its greenhouse gas emissions to 12.5% below 1990 levels by 2008-2012. The UK government has also set a domestic goal of a 20% reduction in carbon dioxide (CO₂) emissions below 1990 levels by 2010. A key requirement of the Kyoto Protocol is that countries show demonstrable progress in meeting their commitments. The work presented in this report contributes to meeting this requirement by providing estimates of the likely impact of selected policies and measures aimed at reducing the direct and indirect emission of CO₂ resulting from industrial energy consumption. The report also extends the availability of industrial sectors for which technologically disaggregated carbon abatement cost curves exist. Entec UK Ltd and Cambridge Econometrics have worked together to undertake this study.

In order to estimate the likely impact of the policies and measures to be analysed, a combination of 'bottom-up' and 'top-down' modelling was employed. ENUSIM (Industrial Energy End-Use Simulation Model), a technology-based, 'bottom up' industrial energy end-use simulation model, was used to partially evaluate the effect of the Climate Change Levy (CCL) on selected industrial sectors. ENUSIM is designed to model the uptake or retrofit of energy saving and/or fuel switching technologies in selected industrial sectors, taking into account both economic factors and assumptions about investment in new technology. The industry-specific abatement cost curves contained in ENUSIM do not, however, include combined heat and power (CHP) stations. The estimated impact of the selected policies and measures on CHP, and the resulting emissions savings, thus had to be estimated using the MDM-E3 (Multi-sectoral Dynamic Model Energy-Environment-Economy) model, which is a 'top-down' model of the UK economy, with fully integrated energy-environment sub-models. Likewise, the impact of the Climate Change Agreements (CCAs) on carbon emissions was calculated 'off-model' using ENUSIM data. Every effort was made to ensure consistency between the different modelling approaches, but care should still be exercised when aggregating the estimates from the different policy measures.

The overall effect of the policies and measures modelled to date is anticipated to be about a 4.5 MtC reduction in 2010 from a baseline (with none of these policies in place). CHP contributes approximately 1.7 MtC to this figure. To put these estimates in context, the estimated impact of a similar set of policies and measures targeted at reducing carbon emissions from business, as presented in the Climate Change Programme (CCP) and Third National Communication (3NC), were 7.0 MtC and 5.8 MtC, respectively.

UKERC hosted an international workshop in Oxford on 30-31 March to discuss the implementation of the Kyoto Protocol. The objective of the workshop was to determine whether and how Kyoto countries intend to deliver their Kyoto targets.

40 participants from Government, business, academia, think-tanks and nongovernmental organisations attended the workshop from 16 countries including several European Member States, Russia, Japan, Canada and Ukraine.

The workshop aimed to explore how the flexible mechanisms of the Kyoto Protocol could better capture the large energy efficiency potential in the CEE region. While implementation of the mechanisms in the region is desired, in practice it is likely to be a challenging task. The workshop has made it possible for two interested groups to meet and learn from each other: one group being participants from the CEE region seeking knowledge transfer and capacity building, and the other group being carbon trading specialists.

The Industrial Strategy is underpinned by an extensive analytical programme. Given the complexity of the decisions involved, no single methodology or information source can encompass all the relevant issues; instead, we analysed quantitative and qualitative evidence from a range of sources using a variety of methodologies and tools. We will continue our programme following the publication of the Industrial Strategy, expanding our analysis as the evidence and the economy itself evolve over the next decade.

The analytical programme was based on literature reviews, data analysis, and engagement. We used engagement to gather feedback on the Industrial Strategy, including on sectors, places, growth barriers and opportunities, and policies; to incorporate evidence and analysis from a range of experts and stakeholders; and to independently validate our analytical programme. Activities included:

As part of Invest 2035 we issued a public consultation asking for feedback on 36 questions to inform the Industrial Strategy. The consultation ran for six weeks over October and November 2024. Responses were submitted online or by email and reviewed by the Department for Business and Trade (DBT) and the research agency Ipsos. Responses supported the analysis identifying frontier industries and places, identifying key economy-wide growth barriers and opportunities, and selecting policy interventions.

The consultation received over 27,000 online answers to individual questions from a wide range of businesses, individuals, academics, think tanks, and trade unions, as well as more than 250 business associations representing hundreds of thousands of businesses across the UK.

Industrial strategies provide an overarching plan for the economy (or key parts of it) that aims to help the government achieve economic, social and/or environmental goals. However, there are many definitions and a spectrum of approaches to the degree and types of government interventions used.

This briefing summarises the government’s 2025 industrial strategy and explains key concepts in industrial strategy theory. It also sketches the international context and includes a brief overview of industrial policy in the UK over the last few decades.

The two workshops aim to:

• elaborate approaches to understanding innovation from different disciplinary perspectives;
• illustrate these approaches through the use of case studies from energy and, where appropriate, other sectors;
• generate common insights and understanding;
• assess policy implications from this understanding for promoting low carbon innovation;
• identify requirements for further research.

The full presentations are available on the UKERC Meeting Place website. This report provides a summary of the presentations and discussions at the first workshop.

This report provides an analysis of the link between investment risks in electricity generation and policy design. The issues it discusses are relevant to a wide range of policy developments in the UK and elsewhere. These include banding the Renewables Obligation, bringing forward the development of power stations with carbon capture, financial support for nuclear power and the future of emissions trading.

This working paper sets out to provide a short introduction to risk and return in making financing and investment decisions in the energy sector, focusing on renewable energy. It will specifically draw on the outcomes of consultation roundtables with financiers on renewable energy policy to illustrate what financiers need from policy to reduce risk and increase returns; what types of issues arise in different policy frameworks; and how policy can affect the attractiveness of different investments. The review of the UK’s Renewables Obligation policy provides a useful focal point for illustrating the latter.

Despite disabled people and low-income families with children being defined in policy as vulnerable to fuel poverty, there is very little evidence about how the needs of these groups are recognised or incorporated into policy decisions. There is alsono clear evidence on how energy efficiency policies actually affect these groups, and whether policy outcomes are consistent across the UK.

This policy briefingauthored by University of Yorks Department of Social Policy and Social Work (SPSW) and ACE Research, explores some of the key gaps in knowledge regarding justice in energy efficiency policy in the UK. The focus was on the impact of energy efficiency policies on disabled people, those with long-term illnesses and low-income households with children.

Key findings

The delivery of energy efciency policy is variable and patchy, with vulnerable groups ingreatest need not always eligible for support, or receiving support which fails to reflect their additional needs. To improve access for vulnerable groups and to meet their needs more effectively, the authors recommenda greater recognition of the needs of vulnerable groups, more consistent approaches across the UK and better cooperation with non-energy sectors.

The researchidentifies five key barriers to accessing vital fuel poverty support mechanisms and suggests ways in which access and outcomes can be improved for all.

• Current energy efciency programme design leads to an emphasis on meeting targets at the lowest cost -the numbers game. There needs to be a greater emphasis on the positive impact of intervention on the household rather than a focus on least cost.
• Households in need are not always eligible and the mechanisms for nding households needs to improve. Greateraccess to high quality data, data matching and data sharing wouldenable households to be targeted more effectively.
• Vulnerable customers are often unaware they are eligible for support and mechanisms for nding these people need to improve. Workis requiredto improve the trustworthiness of some of the schemes promoted.
• Current programmes focus on technical improvements to buildings rather than the needs of vulnerable groups. Thereneeds to be shift towards developing abetter understanding of the needs of these people and how they engage with energy.
• The delivery of existing energy efficiency support programmes across the UK is patchy.Government should aim for consistent outcomes for households wherever they live.

The study has used a systematic selection and analysis procedure to assess each LCA, collating data on the energy and GHG balances of liquid transport fuels and biomass for heat and power. This consistent approach will produce a dataset which can be used to uniquely compare the energy and GHG balances of these two uses of biomass. The representation of collated LCAs as straightforward visual summaries highlights variations within methodology, system boundaries and reporting.

Although this study is ongoing, several issues relating to the lack of transparency of LCA reporting have already become apparent. Common obstacles to reviewing this subject have been in successfully identifying system boundaries, co-product allocation methods and conversion efficiencies used in the LCAs being analysed. Therefore, a set of recommendations for LCA reporting are listed at the end of this report.

Pilot study report

Working with the Energy Technologies Institute, Mags Tingey, Dave Hawkey and Jan Webb completed a pilot study exploring local engagement with energy systems. The work, an extension of the Heat and the City project, examined levels of local engagement across all 434 of the UK's local authority areas, and drew together a wide array of datasets with original collation of data.

Findings show that almost one third (30%) of the UKs 434 local authorities are actively planning, and investing in, energy productivity and provision. Most of this activity is on a limited scale with only 9% of UK authorities showing evidence of significant numbers of energy project investments. We characterised this 9% as 'Energy Leaders' and found they displayed multiple routes into engagement, including economic regeneration, housing upgrades and affordable warmth, energy productivity, avoided costs of alternatives and environmental protection. Particular regions of the show considerably higher levels of local authority engagement, notably London, Scotland, and Yorkshire and Humber, and energy leaders tend to be metropolitan and larger authorities.

Preliminary exploration of the relationship between local authority engagement and levels of low carbon technology deployment (not restricted to local authorities own deployment) shows strong association with non-industrial Combined Heat and Power (CHP). Relationships between engagement and small (under 10MW) renewable electricity generation appears marginally significant. Levelling up deployment of non-industrial CHP across all areas to the levels of the most engaged authorities would imply significant acceleration in deployment rates. The limited pilot research modelling suggests that the impact of this is small (under 10%) in terms of the UK energy production.

This work will continue under the Local energy infrastructure operation & governance projectwith support from the Energy Technologies Institute. This work will use qualitative data gathering to explore some of the quantitative relations our pilot work uncovered, in order to build a better picture of the factors supporting and constraining local engagement with energy. We will also engage with UK energy system modelling to help form a clearer picture of the contribution and impact local energy could realistically have in future.

The brief highlights innovative practices in prevention, repair, and recycling that can transform waste management systems, while acknowledging their interconnected complexities across practices. It underscores the need for local authorities to take a whole-system and cross-sectoral approach, empowering them with resources and policy fr

This report aims to answer the following question: What is the evidence that policy support for investment in renewable energy and energy efficiency leads to net job creation in the implementing regions?

This briefing draws out the key messages from the UKERC report The UK Energy System in 2050: comparing low-carbon resilient scenarios, – which describes and compares a series of model runs, implemented through the UK MARKAL modelling system, which was developed through UKERC with funding from the Research Councils’ Energy Programme. This has revealed some consistent patterns showing how the UK energy system might develop in future, which are discussed in detail in the full report.

This report takes a whole systems approach to the development of the UK energy system over the next 40 years.

Achieving a resilient low-carbon energy system is technically and economically feasible at an affordable cost.

There are multiple potential pathways to a low-carbon economy. A key trade-off across the energy system is the speed of reduction in energy demand versus decarbonisation of energy supply. There is also a number of more specific trade-offs and uncertainties, such as the degree to which biomass, as opposed to electricity and perhaps hydrogen, is used in transport and other sectors.

Deploying new and improved technologies on the supply side will require substantially increased commitment to RD&D, the strengthening of financial incentives and the dismantling of regulatory and market barriers. A major increase in efforts to acceleratethedevelopment of

Mapping energy participation: a systematic review of diverse practices of participation in UK energy transitions 2010-2015. What does public participation in energy transitions look like at a relational 'whole systems' level?

This document sets out some of the theoretical concepts underlying the project Mapping rebound effects from sustainable behaviours and reviews some of the previous studies in this area. The aim is to provide a starting point for the empirical research.

The Paper considers first demand for indium and tellurium from the PV industry, now and in future. Whilst a range of scenarios exist for the role of PV in the global energy mix there is considerable agreement that the share of PV per se and thin film devices in particular is expected to expand considerably in the light of carbon abatement goals.

The paper then considers the supply of indium and tellurium. It provides a detailed review of the processes used to extract and refine them, and discusses the issues associated with producing these secondary metals which are extracted as trace elements during the production of primary metals such as zinc and copper. The Paper finds that there are considerable complexities associated with reported reserves and an absence of meaningful data on resources. Again, existing estimates of availability for the PV market are reviewed. This alsoreveals considerable variation within the literature and the use of a wide a range of assumptions upon which to base resource availability.

The paper concludes that there is no immediate cause for concern about availability of either indium or tellurium. PV occupies a small fraction of current markets and there is evidence of considerable potential to increase the extraction of both metals because a sizeable proportion of the material potentially available from primary metal extraction is not currently utilised. Moreover, there is potential to increase recycling of products containing indium or tellurium, for example from flat screens. However, the scale of the roll out of PV ~ vi ~ envisaged in some scenarios could imply a large expansion in the demand for indium and tellurium. There is no reason to believe that this is not feasible, however adequate data on reserves and resources do not exist. Resource estimates are not available and simplistic assumptions such as using current production or crustal abundance to estimate potential supply cannot provide any meaningful insight into future production. A scenario approach that links production to primary metals is appropriate. We conclude that considerable further research is needed to characterise indium and tellurium resources and the economic feasibility of expanding production.

The paper examines demand for lithium and neodymium from the EV industry. Lithium is used in Li-Ion EV batteries and neodymium is used in permanent magnets in electric motors and wind turbine generators. Global demand scenarios for EVs vary widely, though all anticipate a considerable growth in the EV market over the coming decades, driven largely by decarbonisation goals.

The paper then examines wind turbines, another low carbon use of neodymium. Again global demand for wind turbines and estimates of future material intensity are key to understanding future demand. It is also important to estimate the number of turbines using permanent magnet designs, since generators without permanent magnets are in common use. Decarbonisation goals are predicted to drive demand for wind turbines in the future, with several studies agreeing that future manufacturing of turbines will increase significantly. Based on this analysis, demand for neodymium from wind turbines could be between 600 and 6,000 tonnes per year by 2050.

Policy makers and industry are increasingly concerned over the availability of certain materials key to the manufacture of low carbon technologies. The literature addressing this topic includes reports termed criticality assessment that aim to quantify the relative criticality of a range of materials. In this study we examine the methodologies underpinning these criticality assessments, and attempt to normalise and compare their results. This process identified a list of 10 metals or metal groups for which average normalised scores are presented, along with maximum and minimum scores to indicate the range of uncertainty. We find that criticality assessment methodologies diverge significantly, making comparison difficult. This leads to apparently wide uncertainty in results. We also find that in order to achieve comparability within studies, authors typically rely on simple metrics for which data is available for all metals considered. This leads to some compromises which affect results. Finally we suggest that, given these uncertainties and methodological difficulties, criticality assessments are best used to highlight materials or technologies of particular interest, which should then be further examined in isolation, to improve insight and accuracy.

There is increasing concern that future supply of some lesser known critical metals will not be sufficient to meet rising demand in the low-carbon technology sector. A rising global population, significant economic growth in the developing world, and increasing technological sophistication have all contributed to a surge in demand for a broad range of metal resources. In the future, this trend is expected to continue as the growth in low-carbon technologies compounds these other drivers of demand. This report examines the issues surrounding future supply and demand for critical metals - including Cobalt, Gallium, Germanium, Indium, Lithium, Platinum, Selenium, Silver, Tellurium, and Rare earth Metals.

UKERC co-hosted a meeting last month with DECC and ETI to seek input and feedback on plans for the 300 million in heat network capital expenditures announced in the government's Spending Review. Amber Sharick, UKERC Business Engagement Manager, and Jan Webb, UKERC Researcher & Professor of Sociology of Organisations, University of Edinburgh, report on the discussions.

The west of Shetland region is physically a very different environment to the Gulf of Mexico, so environmental impact of a deep water spill in this area would be different, in many aspects.

A regulatory system could be enacted to compel companies to develop a shareddeep-water rapid response system to cap wells, and the levels of insurance cover companies are obliged to have could be increased.

The UKs regulatory system is robust but could be improved, though there is a limit to which increased regulation can be implemented and effective.

Scenarios which may reduce the need to exploit deepwater reserves during the transition to a low carbon economy are discussed. However, given our current reliance on oil and gas, such exploitation may be necessary.

Under free market regulations the contribution of deepwater reserves to security of supply may be limited, though there may be some economic benefits of exploitation

The reason for producing this note is that two distinct strands of thought can be found in the literature on how to conceptualise the costs associated with any additional capacity required to maintain reliability when intermittent generators are added to an electricity network. The first does not explicitly define a system reliability cost rather it assesses the overall change in system costs that arises from additional capacity (Dale et al 2003). This approach can be used to derive system reliability cost if combined with an assessment of the impact on load factors of incumbent stations when new generators are added (see footnote 2). The second includes an explicit system reliability cost. This approach requires that we make an assumption about the nature of the plant that provides back up(Ilex and Strbac 2002). Both approaches should arrive at the same change in total system costs.

To address the aim, each chapter author presented a 10-minute summary of his chapter. This was followed by a five-minute critique by an invited discussant. Comments were invited from the floor for a further 15-minute period. Professor Gary May provided an overview of research in this area at the end of the workshop. The workshop was opened by an invited chair, Professor A.P. Sakis Meliopoulos of the Georgia Institute of Technology. Professor Meliopoulos offered final concluding remarks.

The issue: a need to better understand the models that inform demand-side energy policy-making

Under the UK Climate Change Act 2008, the government is legally bound to reduce greenhouse gas (GHG) emissions by 80% by 2050 relative to 1990 levels.

Historically, the focus of energy policy in the UK has been on supply-side policies, such as decarbonisation of electricity generation through greater use of low carbon technologies like wind and solar. Increasingly, however, demand-side energy policies are being recognised as having important contributions to make to achieving emission reduction targets, through reducing energy demand or by making energy demand more flexible and compatible with variable renewable energy sources. Such demand-side policies can seek to promote a wide range of technologies and behaviours, for example improved buildinginsulation, reduction in the use of energy intensive materials and increases in teleworking to reduce commuting.

To fully realise the potential of demand-side energy policies, it is important that they can be adequately represented in quantitative energy models, because such models play an important role in informing UK energy policy. However, we do not currently have a good understanding of how well the different energy models that inform UK government energy policy represent energy demand and demand-side energy policies.

Therefore we have undertaken a Rapid Evidence Assessment (a constrained form of systematic review) to examine the energy models that have informed energy policy documents published by the UK government between 2007 and 2017. The overarching question this review seeks to address is:

How suitableare the energy models used toinform UK government energy policy for exploring the full range of contributions that demand-side energy policies can make to climate change mitigation?

Main findings: strengths and weaknesses in existing modelling

Our Rapid Evidence Assessment reveals that the core strength of current energy modelling is the detailed representation of technologies, with many models featuring information on hundreds of potential technological options for increasing energy efficiency. Although uncertainties exist around these technological options, these models allow us to gain a coherent and realistic understanding of how different combinations of technologies could satisfy our future energy service demands under different low-carbon scenarios.

However, the modelling landscape reveals two key limitations with regard to the representationof non-technological drivers of energy demand:

• Firstly, economic, social and behavioural drivers of energy demand, such as thermostat settings, are rarely explicitly included within the models. As a result, changes in such drivers risk being overlooked as potential levers of climate change mitigation. In addition, the economic, social and behavioural assumptions that are included into the models are often not presented in a transparent manner.
• Secondly, while many of the models provide a wealth of detail on different technological options, they are not well-equipped to model how behavioural, social and economic changes impact on the use of technology. This makes it difficult to investigate how technological change comes about and how it could be steered into the right direction using different policy instruments. In many models, the uptake of different technological options is specified exogenously by the user, or is determined within the model by cost optimisation, which does not reflect the many non-cost factors influencing technology diffusion.

Key recommendations for future modelling

• Develop consistent and transparent processes for estimating and presenting the fixed inputs to energy models, such as energy service demands and socio-economic drivers.
• Quantify the potential of demand-side policies and include them as explicit options in energy models to make such policies more visible.
• Improve the representation of economic, social and behavioural processes in energy models where feasible and useful. This endeavour can build on existing research in the academic literature, which is currently not well represented in policydevelopment.
• Research further the potential implications of interactions between different drivers of energy demand and make sure they are consistent. An example of such an interaction would be the impact that a modal shift from cars to cycling would have on the growth and energy demand of the automotive industry.

Despite these benefits, barriers such as regulatory gaps, cultural inertia within the construction sector, and lack of consumer awareness hinder MMCs widespread adoption. In light of current challenges, the study underscores the imp

This report is the first in the UKERC Energy 2050 project series. It focuses on a range of low carbon scenarios underpinned by energy systems analysis using the newly developed and updated UK MARKAL elastic demand (MED) model. Such modelling is designed to develop insights on a range of scenarios of future energy system evolution and the resultant technology pathways, sectoral trade-offs and economic implications. Long-term energy scenario-modelling analysis is characterised by deep uncertainty over a range of drivers including resources, technology development, behavioural change and policy mechanisms. Therefore, subsequent UKERC Energy 2050 reports focus on a broad scope of sensitivity analysis to investigate alternative scenarios of energy system evolution. In particularly, these alternative scenarios investigate different drivers of the UK’s energy supply and demand, and combine the twin goals of decarbonisation and energy system resilience. Future analysis includes the use of complementary macro-econometric and detailed sectoral energy models.

Under the UK Climate Change Act 2008, the government has committed to reduce greenhouse gas emissions by 80% by 2050 relative to 1990 levels (Climate Change Act, 2008). This will require a large shift in the UK’s energy system, ranging from energy production, across transmission to consumption.

The public are implicated in the transition process as energy users, increasingly also as energy producers and as active members of society who might support or oppose energy projects and policies. Previous research (Demski et al., 2015; Parkhill et al., 2013) has shown that there is widespread public support for transitioning to a low-carbon, affordable and reliable energy system – however, this change is associated with costs and it remains to be seen how these costs will be covered.

This research explores the views of the British public on how the energy transition should be financed. Drawing on a survey of 3,150 respondents and focus groups in 4 locations across Great Britain, it investigates what responsibility members of the public assign to government, energy companies and the general public for financing energy system change.

Research findings

The results highlight widespread support for an energy system that ensures affordability, reliability and low carbon energy sources. Energy companies and the government were assigned primary responsibility for contributing financially to energy transition, as they were seen to have the structural power and financial means to implement necessary changes. Respondents also indicated that the general public ought to contribute as well, although the public was perceived to be paying over the odds already (through bills to the energy companies and levies to the government). Nonetheless, research participants expressed willingness to accept between 9-13% of their energy bills going towards environmental and social levies.

Distrust in energy companies and government

Willingness to contribute financially towards the energy transition was also found to be dependent on the perception that energy companies and government are contributing financially and showing real commitment to energy system change. It was also notable that this condition was not currently thought to be met; distrust in this regard was particularly evident in focus group discussions.

Distrust in companies: People believe that the majority of energy companies are driven primarily by profit motives leading to inadequate commitments with regards to energy transition goals such as investing in low-carbon energy and ensuring energy affordability.

Distrust in government: The government, and politicians in particular, are seen as too closely connected to the energy industry, leading to inadequate and ineffective regulation of energy companies and their opaque practices.

Examining what underlies people’s distrust, it is evident that the public has a number of justice and fairness concerns that need to be addressed. In particular, beliefs concerning distributive justice (i.e. how costs are distributed across society) and procedural justice (i.e. respectful treatment, transparent practices and decision-making) are important for public acceptance of responsibility and costs.

Key recommendations

Addressing the issues underlying the trust deficit will be challenging, but this is nonetheless important if we are to ensure that there is to be broad societal consent and engagement with the low-carbon energy transition. To begin this process, the briefing includes the following recommendations:

1. Government and energy industry must show strong and clear commitments to low-carbon energy system change
2. Greater transparency and accountability regarding costs, decision-making and practices in relation to financing energy transitions
3. Greater clarity and justification for how money is spent by government and energy companies
4. Innovative thinking on how to distribute current and future costs in a fair manner across society
5. Finding ways to credibly show that energy companies are not driven by profits alone
6. Robust and consistent evidence of clearer separation between government and the energy industry

This working paper explores what people may need to know, learn and have if aPersonal Carbon Allowances (PCA) scheme was implemented, and suggests ideas forpolicies, programmes and initiatives that could support them. A PCA scheme impliesthat individuals would have a personal budget of carbon credits, which they wouldneed to manage, to some extent, in order to stay within its limits, and in the bestcase scenario earn some money by selling not-needed carbon credits. Thus, thispaper looks at the budgeting process from the carbon account holders view pointand applies insights from how people budget under monetary and non-monetaryconstrains to the study of PCA. It also highlights related policy design issues.

The paper is composed of two sections. The first sets PCA in the policy contextalongside other existing and proposed emissions reduction policies. Next it explainsthe mechanisms through which PCA supposes to change energy demand behaviourand then describes the current discourse surrounding PCA in the UK. The secondsection lays out the rational for examining PCA through the lense of budgeting andpoints at questions arising from the concept of living within a carbon budget. It then discusses in detail the prerequisites for carbon budgeting, which include: setting the budgetary limits; knowing personalised carbon income and expenditure; having low carbon alternatives; having the opportunity to perform low carbon choices; receiving advice and support; and learning how to trade. This is followed by a short concluding section.

Personal carbon trading (PCT) is a proposed quantity-based policy instrument for reducing the carbon emissions emitted by individuals. The aim of the scheme would be to deliver guaranteed levels of carbon savings in successive years in an equitable way. A PCT scheme would set a total cap on all carbon emissions generated from the fossil fuel energy used by individuals within the home and for personal transport, including those emissions from air travel. In the UK these personal emissions account for approximately half of all carbon emissions. A PCT scheme would be part of an economy-wide emissions trading scheme.

A recent Government study into personal carbon trading1 (PCT) concluded that as a policy instrument PCT has potential to engage individuals in taking action to combat climate change, but is essentially ahead of its time and expected costs for implementation are high.2 . Yet, at the same time Defra has recognised that further research is being taken forward by academics and research institutions outside of Government, and Defra will keep a watching brief on their progress3 . PCT related research studies being undertaken in different universities and institutions across the UK, or overseas, have not yet been brought together in a coherent way and interaction between researchers has been limited. In addition, the Defra studies have highlighted some areas for further research. Thus, the key aims of the workshop were to:

1. Map the field of PCT research: learn what each of us is doing and our respective research focus;
2. Determine where we have got so far, in terms of knowledge and understanding of PCT and its related issues;
3. Discuss future research directions with regard to funding opportunities;
4. Create a PCT researchers network; and
5. Discuss and agree the process for publishing a PCT edited volume through the Climate Policy journal that provides a comprehensive, state-of-the-art review of PCT research to date.

These key aims have largely been met. In the Appendix of the main report is a document setting out the research interests of the workshop participants, giving a flavour of who is doing what where. The Climate Policy journal has expressed interest in publishing a special issue on PCT in early 2010. Papers for this special issue are now being coordinated by the Environmental Change Institute of the University of Oxford.

This report presents the key outputs from the workshop on Place and Energy: Does scale matter? which took place on 21st August 2006 at Imperial College, London and was hosted and sponsored by the UK Energy Research Centre Meeting Place.

The aim of the workshop was to identify the research and policy issues in developing a multi-level energy policy that takes place and the relationships between scales seriously, which would be of value to both policy and practice

With these challenges in mind this report uses UKERC research findings on local and regional energy system development to make recommendations for effective local planning to accelerate net zero energy systems.

This briefing note provides a short introduction to the application of the ecosystem services approach in enabling the sustainable transformation to a low-carbon energy system.

The Policy Pathways to Justice in Energy Efficiency working paper addresses two key gaps in knowledge regarding justice in energy efficiency policy in the UK. Despite disabled people and low-income families with children being defined in policy as vulnerable to fuel poverty, there is very little evidence about how the needs of these groups are recognised or incorporated into policy decisions. There is also no clear evidence on how energy efficiency policies actually affect these groups, and whether policy outcomes are consistent across the UK.

The research was undertaken by researchers at the University of York and ACE Research and was supported by Disability Rights UK and The Childrens Society. One hundred and twenty-five households and practitioners were interviewed as part of the research. In addition to this working paper, acondensed policy guide is also available, as well as separate guides for practitioners who focus on the needs of disabled people, and families on low incomes.

Summary of findings

The research team found that disabled people and low-income families with children often had higher energy demands within the home compared to other households. These increased demands are often associated with keeping warm, additional laundry needs, and in some cases using energy intensive equipment such as dehumidifiers and nebulisers. These circumstances lead to both increased household energy costs and higher risks associated with disconnection and a drop in household temperature.

Despite these needs, and the intention of policy to support households in this position, interviewees described accessing information and advice about energy and energy efficiency as a minefield, high levels of mistrust in the energy sector, and finding it difficult to know where to go and which sources to trust.

The report reveals the delivery of energy efficiency policy is variable and patchy, with vulnerable groups in greatest need not always eligible for support or receiving support which fails to reflect their additional needs. To improve access for vulnerable groups and to meet their needs more effectively, the report recommends there be a greater recognition of the needs of vulnerable groups, more consistent approaches across the UK and better cooperation with non-energy sectors.

Barriers to accessing fuel poverty support

The report identifies five key barriers to accessing vital fuel poverty support mechanisms and suggests ways in which access and outcomes can be improved for all.

• Current energy efficiency programme design leads to an emphasis on meeting targets at the lowest cost the numbers game and there needs to be a greater emphasis on the positive impact of intervention to the household rather than a focus on least cost.
  
• Households in need are not always eligible and the mechanisms for finding households needs to improve, including greater access to quality data, data matching and data sharing to enable households to be targeted more effectively.
  
• Vulnerable customers often are not aware they are eligible for support and mechanisms for finding these people need to improve, together with work to improve the trustworthiness of the schemes promoted.
  
• Current programmes focus on technical improvements to buildings rather than the needs of vulnerable groups and there needs to be shift to understanding the needs of these people and how they engage with energy.
  
• The delivery of existing energy efficiency support programmes across the UK is patchy and Government should aim for consistent outcomes for households wherever they live.

Energy is a crucial element for development in almost every aspect of community life such as education, health, food, and security, and it can contribute to farming productivity, income generation, and the creation of networks that enable youth to work from their villages. Despite this, around 1 billion people globally do not have access to sustainable energy sources, and 80% of those people live in rural areas across 20 countries in Asia and sub-Saharan Africa. To decrease this energy access gap, and to improve rural livelihoods and increase economic opportunities in rural areas, Productive Uses of Energy (PUE) offer an untapped opportunity: examples of PUE include irrigation and post-harvest processing.

Despite the benefits of PUE, they are often not considered in the planning off-grid rural electrification developments. This may be partially attributed to a lack of capital; riskyframework conditions; and a lack of clear policy guidelines available on the subject. The latter of which was the focus of this research project.

Delivered as part of the Energy-PIECES project, this report was developed during a secondment with Practical Action.

• indicate the capacity of nuclear power likely to be generated from anticipated Gen III+ nuclear plant designs developed at existing nuclear sites, anticipated thermal power station brownfield sites, and new greenfield sites;
• indicate the number of sites likely to be suitable for CCS and identify where there is likely to be a conflict of sites suitable for both technologies (CCS and nuclear);
• identify the individual siting constraints which have greatest impact on the three nuclear expansion scenarios identified;
• through a range of sensitivity studies, identify potential changes in site selection criteria which would be necessary to deliver sufficient sites for the nuclear expansion scenarios;
• make recommendations for the siting characteristics of alternative technologies to make good the shortfall from Gen III+ nuclear; these are expected to include a reduced requirement for cooling water;
• identify other issues, constraints or assumptions which may change over the next 35 years to make more sites available for Gen III+ nuclear capacity; and
• identify preferred locations for nuclear power technology demonstrator sites.

The following analysis revisits the relationships between the reserve requirements, the capacity margins needed to maintain the reliability of supplies, the costs of intermittency, the capacity credit for intermittent generation, and several other quantities. It is not put forward as a substitute for full-blown modelling studies, but does provide a reminder of principles and an independent means of checking results. It rests on a few key parameters, principally the means, standard deviations and ranges of the frequency distributions of the various quantities. Whilst this is a simplification, it helps to make the underlying relationships more transparent and enables the analyst to explore the effects of changes in assumptions. It begins with a basic case and then relaxes the assumptions.

There are three questions which recur throughout the paper:

1. What are the required additions to reserves to maintain the reliability of supplies when intermittent generation is substituted for thermal generation? It is unquestionable that the margin will need to rise when the variance of thesupplies increases if supply reliability is to be maintained—but by how much? An alternative way of putting the question is what is the ‘capacity credit’ (defined below) that can be given to intermittent generation?
2. What is the associated increase in system costs that would result from building more wind and less thermal generation?
3.  At the project level, how can we compare the costs of a large wind farm say with the thermal alternative? To answer this, we need to know the answer to (1) above—how much extra ‘reserve’ or ‘backup’ capacity is required for the intermittent resource, and of course what its costs will be.

The paper does not answer questions as to what the optimum reserve margin should be or how it should be determined. There is a long debate on the role of markets and regulation for determining reserve margins which this paper does not get into. Suffice it to say that whatever policy position is taken: (a) in actuality there is at all times a reserve margin, which is the difference between available capacity and demand; (b) this quantity is of interest and needs to be monitored since when it declines the probability of losing load increases; (c) when for policy purposes estimates of the costs of introducing intermittent resources onto the system are being made it is necessary to compare like-with-like such that the costs of introducing them, including the costs of maintaining the reliability of supplies, can be compared with the costs of the alternatives.

This paper argues that reducing the impacts of aviation should be treated as a priority by those interested in averting climate change, and that the scale of reduction needed can only be achieved through demand restraint i.e. discouraging people from flying. Economic policy potentially has a key role to play in this process. The UK Government has the power to introduce a number of economic measures to complement the EU Emissions Trading Scheme, and these measures probably offer the best hope of starting to restrain demand in the immediate future.

This report considers the role and importance of electricity cost estimates and the methodologies employed to forecast future costs. It examines the conceptual and empirical basis for the expectation that costs will reduce over time, explains the main cost forecasting methodologies, and analyses their strengths, limitations and difficulties. It considers six case study technologies in order to derive both technology specific and generic conclusions about the tools and techniques used to project future electricity generation costs.

Using biomass to provide energy services is one of the most versatile options for increasing the proportion of renewable energy in the existing system. This report reviews metrics used to compare alternative bio-energy pathways and identifies limitations inherent in the way that they are calculated and interpreted. It also looks at how companies and investors approach strategic decisions in the bio-energy area.

This report describes the findings of a nationally representative British survey (n=961) conducted in March 2013. The main aim of the survey was to assess British attitudes to nuclear power and climate change two years after the Fukushima accident. The results are compared to a number of British surveys that were conducted at different stages before and after the Fukushima accident (2005, 2010, 2011, and 2012). This provides an overview of how public attitudes to nuclear and climate change have developed over the past decade and in particular after the Fukushima accident. In the longer term the data will be used for more detailed cross-national comparisons with Japan.

The work by Poortinga and colleagues (2013) has shown that British and Japanese publics have responded very differently to the Fukushima accident. However, the surveys included in the analyses were not specifically designed to examine the impacts of the Fukushima accident and contained different sets of questions. Comparisons could therefore only be made on a small number of items.

This new survey builds upon the previous work conducted by the authors of the study (Poortinga et al., 2006; Spence et al., 2010; Aoyagi et al., 2011; Demski et al., 2013) and examines British attitudes to nuclear power and climate change two years after the Fukushima accident. The British survey was coordinated with a similar survey in Japan allowing a detailed cross-national comparison of the long-term impacts of the Fukushima accident on public attitudes to nuclear power and climate change. The Japanese survey was conducted in February 2013 (Aoyagi, 2013).

This report describes the main findings of the British survey conducted in March 2013. The results are contrasted with previous British surveys where possible (i.e. Poortinga et al., 2006; Spence et al., 2010; Demski et al., 2013). Technical details of the previous surveys are provided in Box A. In the longer term, the data will be used for more detailed statistical analyses and cross-national comparisons with Japan.
