In The Birth of Energy (2019), Cara New Daggett offers an incisive critique of the dominant thermodynamic concept of energy. 'Energy', Daggett shows, is inextricably tied to an exploitative productivist politics that extols the virtues of work and the sins of waste. In this paper, I seek to develop new conversations between Daggett's account in The Birth of Energy and an important empirical development within the energy industry that Daggett herself does not consider: the smart grid. The paper draws upon a mixed-methods research project, investigating a UK smart grid trial called 'OpenDSR' devised and implemented by Manchester-based co-operative Carbon Co-op, with funding from the UK government. I draw on my research within OpenDSR to make two interconnected arguments. Firstly, I argue that the smart grid sees an intensification of the energy-as-work logic that Daggett opposes, taking pre-existing preoccupations with calculation and measurement within the energy system to new extremes in pursuit of the maximisation of efficiency and the minimisation of waste. I then proceed to think through the political implications of this argument, contending that while the smart grid reproduces the dominant energy logic that Daggett critiques, it might still have a part to play within an emancipatory environmental politics. In making this claim, a second argument emerges, constituting a sympathetic critique of Daggett's account more broadly. Daggett offers an incisive and important contribution that does much to develop debates within the energy social sciences and humanities. However, I suggest that her account risks obscuring some important political differences between variegated forms of work and waste: while she makes a persuasive case for an anti-work conceptualisation of energy that portends liberation from waged labour, her analysis of the kinds of 'efficiency' that pertain to the energy system seems less compelling.

Purpose: This research aims to examine the main findings of the SusTEACH study of the carbon-based environmental impacts of 30 higher education (HE) courses in 15 UK institutions, based on an analysis of the likely energy consumption and carbon emissions of a range of face-to-face, distance, online and information and communication technology (ICT)-enhanced blended teaching models. Design/methodology/approach: An environmental assessment of 19 campus-based and 11 distance-based HE courses was conducted using questionnaire surveys to gather data from students and lecturers on course-related travel: the purchase and use of ICTs and paper materials, residential energy consumption and campus site operations. Results were converted into average energy and CO2 emissions, normalised per student per 100 study hours, and then classified by the primary teaching model used by lecturers. Findings: The main sources of HE course carbon emissions were travel, residential energy consumption and campus site operations. Distance-based HE models (distance, online and ICT-enhanced teaching models) reduced energy consumption by 88 per cent and achieved significant carbon reductions of 83 per cent when compared with campus-based HE models (face-to-face and ICT-enhanced teaching models). The online teaching model achieved the lowest energy consumption and carbon emissions, although there were potential rebound effects associated with increased ICT-related energy consumption and paper used for printing. Practical implications: New pedagogical designs using online and distance-based teaching methods can achieve carbon reductions by reducing student travel via residential and campus accommodation. Originality/value: Few studies have examined the environmental performance of HE teaching models. A new classification of HE traditional, online and blended teaching models is used to examine the role of ICTs and the likely carbon impacts.

The pace of commercial graphic design practice presents very few opportunities to conduct user research after a project's launch. This makes the design team's ability to anticipate and address risks during the design development phase even more important, recognized in the astute observation from Tim Brown, CEO of leading international design group IDEO, that sometimes you must "fail early to succeed early." This paper presents the methods and strategies used by the Centre for Design Research's (CfDR) creative team to mitigate risk during three communication design case-study projects. Elements of failure are identified in each of the three cases and presented, with discussion of where and why they occurred, and the possible approaches for reducing the risk of such problems re-occurring. To provide structure to the discussion, the paper frames each contributory issue as either a usability, communication or technical failing. The analysis demonstrates that the factors contributing to design process failures are often complex and multi-layered. To avoid a poor design project outcome, it is evident that consistent risk monitoring is present in all stages of a design project, but might be improved by better understanding how issues change their degree of importance and potential negative impact during the course of the project. Developing a mechanism to enable teams to objectively identify and manage these fluctuating project risks, will contribute to a more coherent and effective strategy for recognizing and managing future design projects.

Purpose: The purpose of this paper was to enhance and complement teaching about resource system feedbacks and environmental modelling. Students were given an interactive exercise based on a research model (ForeseerTM), developed by an inter-disciplinary research team, that explores the interconnectivity of water, energy and land resources. Two groups of students were involved, one of undergraduates and the other of graduates. Design/methodology/approach: The Foreseer model represents physical flows of the three resources (water, energy and land) using an interactive visual interface. The exercise was set up by giving students short instructions about how to use the tool to create four scenarios, and an online questionnaire was used to capture their understanding and their ability to extract information from the model. Findings: The exercise proved to be a helpful way to connect research and teaching in higher education, to the benefit of both. For students, it was an interactive and engaging way to learn about these complex sustainability issues. At the same time, it provided tangible feedback to researchers working on the model about the clarity of its user interface and its pedagogic value. Originality/value: This exercise represents a novel use of a resource model as a teaching tool in the study of the water, energy and land nexus, and is relevant to sustainability educators as an example of a model-centred learning approach on this topic.

Energy sustainability is prevalent in political and popular rhetoric and yet energy consumption is rising. Teenagers are an important category of future energy consumers, but little is known of their conceptions about energy and energy saving. We report on empirical research with two groups of teenagers. This is part of ongoing work to design learning technologies that support teenagers learn about personal energy consumption. In this paper we describe our analysis and methodology, which are shaped by the Ecology of Resources (EoR) design framework [Luckin, R. (2010). "Re-designing learning contexts: Technology-rich, learner-centred ecologies". London and New York, NY: Routledge]. Our findings informed the development of an EoR model of the participants' personal context, which includes their world resources (people, tools, knowledge, skills, and environment) and their personal resources (conceptions, motivations and concerns around energy consumption). We discuss the range of methods we employed to understand learners' personal contexts. These findings contribute to our understanding of how to explore teenagers' personal contexts and have implications for the design of technology to support learning about personal energy consumption.

The current use of two sets of units in the UK continues to be a source of muddle and confusion. Young people are taught metric (SI) units in school but, in the outside world, still have to contend with units such as inches, feet, pounds, stones and miles. Specialist teachers and practitioners of the sciences are not blameless. This paper considers the fact that some units commonly used in physics, astronomy, and physics education are unnecessary, involve time-wasting conversions and frequently lead to confusion or even error. This unsatisfactory situation is illustrated by examples, and suggestions are made for a radical improvement.

Purpose: This paper aims to investigate students' energy literacy at a UK university, and recommends ways in which it can be enhanced using a behaviour change model. Developing students' energy literacy is a key part of the "greening" agenda, yet little is known about how students develop their ideas about energy use and energy saving at a university. Design/methodology/approach: The research utilised a mixed-methods approach including an online survey (with 1,136 responses) and focus groups. Findings: The research identified strengths and weaknesses in students' energy literacy, and noted the relative influence of formal and informal curricula. The potential for aligning these curricula is highlighted through the 4Es model of enable, engage, exemplify and encourage. Research limitations/implications: The research involved a single instrumental case-study site. The wider applicability of the findings should therefore be tested further in other institutions. Practical implications: The research suggests ways in which universities might better support their students in making more sustainable energy-related behaviour choices, and it indicates the importance of knowledge as well as attitudes. Social implications: The research may have implications for the energy-saving behaviours of individuals in the wider society. Originality/value: Attempts to reduce energy use in higher education are widely seen in campus operations. This research provides an indication of the potential for enhancing energy-saving through different forms of curricula.

This paper is a reflective account exploring the value of using action research in a relatively new context in the United Kingdom; the development of community renewable-energy projects. There is a strong rationale for using action research in this setting due to the synergies between the principles and practice of action research and localised renewable energy provision, which simultaneously aims to empower communities and address the complex social problem of climate change. A doctoral study of the development and impacts of community renewable energy projects using an action research approach provided an opportunity to assess the benefits and challenges of following this approach in this setting. Personal reflection on the research process is used to evaluate the outcomes for researcher and co-participants, and to identify opportunities for future application of action research techniques to improve understanding of how to develop community-based approaches to renewable energy provision and other sustainability issues.

This paper reports findings from a study of young children's views about electric circuits. Twenty-eight children aged 5 and 6 years were interviewed. They were shown examples of circuits and asked to predict whether they would work and explain why. They were then invited to try out some of the circuit examples or make circuits of their own choosing. Children expressed a variety of views about the connections needed in a circuit, offered different kinds of explanation and showed differing levels of competence in circuit making. The range of responses showed similarities to those of older students found in previous research. The relationship between practical competence, prediction, and explanation was not straightforward. For example, children with similar levels of practical competence made different predictions or offered different kinds of explanation. Analysis of the circuits children chose to construct suggested influences of existing competence and knowledge. In particular, some children tested out circuit examples about which they had been unsure during the interview, while others explored circuit connections more generally. Findings underline the importance of drawing on a variety of evidence in assessing young children's understandings of electric circuits. They indicate that young children may offer views about electric circuits not unlike those of older children and adults with similar experience. Finally, there was some suggestion that the interview procedure may have acted as an instructive stimulus in helping children to become more conscious of their own views and reflect on their thinking in the light of further evidence.

Assessment in engineering disciplines is typically oriented to demonstrating competence in specific tasks. Even where assessments are intended to have a formative component, little priority may be given to feedback. Engineering departments are often criticized, by their students and by external quality reviewers, for paying insufficient attention to formative assessment. The e[superscript 3]an project set out to build a question bank of peer-reviewed questions for use within electrical and electronic engineering. As a part of this process, a number of engineers from disparate institutions were required to work together in teams, designing a range of assessments for their subject specialisms. The project team observed that lecturers were especially keen to develop formative assessment but that their understanding of what might be required varied considerably. This paper describes the various ways in which the processes of the project have engaged lecturers in actively identifying and developing their conceptions of teaching, learning and assessment in their subject. It reports on an interview study that was conducted with a selection of participants. It is concluded that lecturers' reflections on and understanding of assessment are closely related to the nature of the subject domain and that it is essential when attempting to improve assessment practice to start from the perspective of lecturers in the discipline.

The present energy crisis is one which is rooted in the contradictions of the neoliberalisation of energy. The UK is one of the pioneers of energy neoliberalisation and has been experimenting with different market arrangements since the 1980s, yet has found itself particularly exposed to the impacts of a global energy price shock. Through an analysis of policy documents, regulatory reports and historical energy policy literature, I identify how privatisation, regulatory experiments and market engineering under a neoliberal policy paradigm helped to create the conditions for the present crisis. Drawing on Hall's conception of policy paradigms, I argue that the neoliberal policy paradigm, for energy, is locked in a cycle of interventions at the second order to manage the contradictions of the third order priority of securing privatised energy markets and maintain legitimacy for the neoliberal energy system. The current energy crisis has led to the government making increasingly extreme second order interventions to stabilise the energy system to secure the interests of electricity capital and fossil capital. The present crisis, however, exposes the limits to a socio-ecological fix (for people, and for capital) within neoliberal hegemony. [ABSTRACT FROM AUTHOR]

The UK has some of the oldest buildings in Europe. They are also some of the worst performing in terms of energy performance. In tandem with these issues the UK has committed to making a substantial reduction in CO2 emissions. UK homes are currently responsible for almost 20 per cent of CO2 emissions. This leaves little option other than to make considerable progress with the retrofitting of homes to improve their energy performance. This is a technical process, however, and can introduce risks to building and their occupants. Examples exist of homes being retrofitted with disastrous consequences. Some of these issues can be due to the lack of thorough examination of a home before it undergoes a retrofit. This paper proposes a method that provides a detailed pre-retrofit assessment of a home, to fall in line with PAS 2035, a standard that provides guidance around publicly funded retrofit in the UK.

The UK government aims to transition its modern natural gas infrastructure towards Hydrogen by 2035. Since hydrogen is a much lighter gas than methane, it is important to understand the change in parameters when transporting it. While most modern work in this topic looks at the transport of hydrogen-methane mixtures, this work focuses on pure hydrogen transport. The aim of this paper is to highlight the change in gas distribution parameters when natural gas is replaced by hydrogen in the existing infrastructure. This study uses analytical models and computational models to compare the flow of hydrogen and methane in a pipe based on pressure loss. The Darcy-Weisbach and Colebrook-White equations were used for the analytical models, and the k- ε model was used for the computational approach. The variables considered in the comparison were the pipe material (X52 Steel and MDPE) and pipe diameters (0.01m–1m). It was observed that hydrogen had to be transported 250–270% the velocity of methane to replicate flow for a fixed length of pipe. Furthermore, it was noted that MDPE pipes has 2–31% lower pressure losses compared to X52 steel for all diameters when transporting hydrogen at a high velocity. Lastly, it was noted that the analytical model and computational model were in agreement with 1–5% error in their findings. [Display omitted] • Hydrogen is expected to replace methane by 2035 for domestic heating applications. • Analytical and computational models were used to compare flow of hydrogen and methane. • Hydrogen velocity must be up to 2.7 times faster than methane to replicate flow. • MDPE pipes showed lower pressure losses than steel pipes due to reduced roughness.

Purpose – This legal update examines the implications for commercial landlords of regulations required to be made under Energy Act 2011, and to come into force by 1 April 2018. Under those regulations, a landlord “may not let” commercial premises falling below a specified energy performance rating (likely to be E). The sanction of market deprivation arguably represents a significant shift in the balance between incentive and compulsion as the key policy tool adopted by the UK Government in seeking to improve the energy performance of commercial buildings. The paper aims to discuss these issues. Design/methodology/approach – The paper sets out and reflects a practitioner's concerns relating to the proposed new sanction of market deprivation. It identifies and highlights practical difficulties likely to be encountered when considering the interaction of the proposed regulations with existing statute (e.g. Landlord and Tenant Act 1954) and contractual provisions such as tenant break clauses. Findings – The prospect of being unable to let commercial premises that fall below a specified energy efficiency rating must focus landlord attention on rights to enter to carry out improvement works. The paper identifies a potentially significant trap for landlords in the model green lease clauses issued by the Better Buildings Partnership where tenant consent is required. Research limitations/implications – The paper does not reflect extensive or exhaustive academic research. Consistently with its purpose a legal update, it identifies key issues likely to be encountered by practitioners. Practical implications – The principal practical implication is the need for landlords and their professional advisors to consider as part of any current lease negotiations the need to secure rights of entry for landlords to carry out improvement works where premises are at risk of falling below the energy performance rating likely to be specified in regulations to be made under Energy Act 2011, s 49. Originality/value – The paper reflects a practitioner's views, developed through client matters and also through designing and delivering professional training sessions, on the likely implications of the requirement for regulations under Energy Act 2011.

This paper responds to the need for a greater integration of energy and environment themes in the higher education curriculum. We explore the practical implications of empowering students towards the implementation of individual action research projects focused on investigating and addressing insufficient or wasteful energy consumption among households and businesses. The paper scrutinizes a series of teaching and assessment activities within this domain, undertaken during 6 consecutive academic years – between 2008 and 2013 – within a third-level undergraduate course unit at the University of Birmingham in the United Kingdom. Using questionnaire surveys, assessed projects and interviews with the students, we have found evidence to suggest that the action research projects contributed to the emergence of constructive alignment in the entire teaching process, while opening the space for informal action learning ‘sets’ leading to the generation of new problem-solving skills useful in the job market.

Energy demand associated with energy consumption (commonly fossil fuels) has increased in line with the rise in world population and this has led to a number of complications. The best known and most prominent issue induced by fossil fuel utilization is unavoidable greenhouse gas emissions released as a result of the combustion of fuels. Emitted greenhouse gases from various sources, such as industrial plants, power plants, transportation services, residential utilization and so on, are largely responsible for global warming and climate change. According to latest reports, the share of the transportation sector in total energy-related CO2 emissions is approximately 23%. As a result of a detailed investigation and dissemination of transportation-induced emissions, air transportation is found to be responsible for approximately 3–4% of total energy-related CO2 emissions. The current study introduces a different perspective in the evaluation of aircraft greenhouse gas emissions. In this manner, a thermodynamic evaluation on the basis of the first and second laws of thermodynamics and a cost evaluation of greenhouse gases emitted from domestic flights in the UK are presented in the current paper, in addition to an environmental impact assessment.

Solar thermal systems have encountered a high level of interest over the last ten years due to their low cost and convenience in reducing energy load for domestic hot water. This paper aimed to introduce a new panel's material (Versa Tyle GRP Tiles) for solar thermal system and a prototype was built in a small shed at a site in Liverpool (UK), in order to assess its performance. The experiment was run for 12 months for the purpose of collecting and analyzing thermal data in terms of heat capacity, solar energy, and solar fraction. To simulate the daily use of water consumption and provide realistic outputs, the system was emptying every day at different durations in order to investigate the recovery period of the temperatures. The results proved the feasibility and efficiency of the Versa Tyle GRP as the maximum recorded temperature on the tiles was 68°C, and 51°C for the hot water in July; while winter months recorded a maximum of 26°C for the hot water. The system achieved average solar fraction of 36.52–47.43% between May to September, while in the rest of the months in the year, average solar fraction of 2.95%-18.59% were detected.

The interface of a long-standing movement for sustainability at the urban scale and the imperatives of the carbon-reduction agenda are driving change in urban energy systems. This paper seeks to address the nature of that change and, in particular, to consider how different pathways of change are emerging. To do this it draws on the coevolution and pathways literatures to interrogate a database of current urban energy initiatives within the UK. This analysis reveals the multiple pathways of change though which new modes of energy production and consumption are being developed to deliver carbon reductions through the reconfiguring of urban energy systems. The paper concludes with a discussion of the implications of these changes for urban governance and for carbon reductions. [ABSTRACT FROM AUTHOR]

The research and evaluation needs to support radical decarbonisation in the built environment are examined for the UK. Since buildings account for approximately 40% of UK energy demand, energy use in buildings will need to be transformed if ambitious climate policy objectives are to be met. In the context of wider energy system change, the needs are for greater efficiency, greater use of electric technologies such as heat pumps as electricity become cleaner, and the use of renewable heat such as biomass. At the same time, the introduction of smart technology offers new opportunities to measure and evaluate changes in demand patterns and the impact of policy interventions. The paper notes that the technical and social dimensions of radical decarbonisation are intimately intertwined. Therefore, social and economic research has a vital role to play in supporting the design and implementation of effective policy, taking advantage of new data-collection opportunities. Drawing on lessons from other policy domains, the paper explores the role that rigorous policy evaluation techniques, little used in the energy domain, could play. It identifies a range of concerns, relating to the political sphere, policy delivery and consumer acceptance, that would need to be addressed. Il est procédé à l'examen pour le Royaume-Uni des besoins en matière de recherche et d'évaluation pour appuyer une décarbonisation radicale dans le cadre bâti. Etant donné que les bâtiments représentent 40 % environ de la demande énergétique britannique, la consommation d'énergie dans les bâtiments devra être transformée si l'on veut atteindre des objectifs ambitieux en matière de politique climatique. Dans le contexte d'une évolution plus large du système énergétique, les besoins portent sur une efficacité accrue, une plus grande utilisation de technologies électriques telles que les pompes à chaleur au fur et à mesure que l'électricité devient plus propre, et l'utilisation d'une source de chaleur renouvelable telle que la biomasse. Dans le même temps, l'introduction des technologies intelligentes offre de nouvelles possibilités de mesurer et d'évaluer les changements intervenant dans les schémas de la demande et l'impact des interventions de politique. L'article note que les aspects techniques et sociaux d'une décarbonisation radicale sont intimement liés. En conséquence, les travaux de recherche dans le domaine social et économique ont un rôle essentiel à jouer dans l'appui à apporter à la conception et à la mise en oeuvre d'une politique efficace, en tirant parti des nouvelles possibilités de collecte de données. Tirant les enseignements des autres domaines d'intervention politique, l'article examine le rôle que pourraient jouer les techniques rigoureuses d'évaluation des politiques, peu utilisées dans le domaine de l'énergie. Il identifie un éventail de préoccupations, en rapport avec la sphère politique, la mise en oeuvre des politiques et leur acceptation par les consommateurs, auxquelles il conviendrait d'apporter des réponses.

The UK government is committed to reducing carbon dioxide emission levels by 80%, comparative to the 1990 baseline, by 2050. 'Nearly-zero-energy buildings' (nZEBs) were introduced by the Energy Performance Building Directive (recast) in 2010 as a realistic solution to the intrinsic environmental debt associated with most existing buildings. This paper aims to carry out a life-cycle cost (LCC) analysis to identify what is a cost-optimal level and how best to achieve this by examining and focusing on the exploration of realistically applicable energy-efficient measures and retrofit scenarios for a typical UK dwelling. A sensitivity analysis is used to identify uncertainty and provide the expected economic benefits and losses of the applied scenarios over their respective lifetimes. It was established that the total LCCs of all the retrofit scenarios were in fact lower than that of the baseline scenario (i.e. not retrofitting the property) over the 30-year study period. Furthermore, it was found that the cost-optimal level for the retrofit of a typical UK residential dwelling is 75 (kWh/m2)/year; meanwhile, the UK's current nZEB target stands at 44 (kWh/m2)/year, meaning that there is a gap between the current nZEB target and the calculated cost-optimal level.

A primary drawback of solar thermal technologies, especially in a domestic setting, is that collection of thermal energy occurs when solar irradiance is abundant and there is generally little requirement for heating. Thermochemical Energy Storage (TCES) offers a means of storing thermal energy interseasonally with little heat loss. A combination of a Solar Thermal Collector (STC) and TCES system will allow a variety of different heating applications, such as domestic space and hot water heating as well as low temperature industrial process heat applications to be met in a low carbon way. This paper describes and assesses the feasibility of two novel technologies currently under development at Loughborough University; i) an evacuated flat plate STC and ii) composite TCES materials, coupled together into a system designed to store and supply thermal energy on demand throughout the year. Experimental results of composite TCES materials along with predicted performance of STC's are used within a developed model to assess key metrics of conceptual TCES + STC systems feasibility, including; charging time, payback time, cost/kWh, energy savings and CO 2 savings. This paper demonstrates the economic, energy and carbon savings potential of conceptual TCES + STC systems suitable for domestic use. • Economic feasibility of novel TCES + STC conceptual systems presented. • Conceptual systems using a Vacuum Flat Plate Collector are the most economical. • 30% of the domestic space heating demand can be supplied using these systems. • Significant CO 2 reductions possible if systems installed in UK households. • Systems predicted to result in financial savings to the homeowner.

Background Estimates of energy requirements are needed in weight management and are usually determined using prediction equations. The objective of these two systematic reviews was to identify which equations based on simple anthropometric and demographic variables provide the most accurate and precise estimates of (1) resting energy expenditure (REE) and (2) total energy expenditure ( TEE) in healthy obese adults. Methods Systematic searches for relevant studies in healthy adults with body mass index ( BMI) ≥25 kg m−2 and published in English were undertaken using Cinahl, Cochrane Library, OpenGrey, PubMed and Web of Science (completed March 2014). Search terms included metabolism, calorimetry, obesity and prediction equations. Data extraction, study appraisal and synthesis followed guidelines from PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Results From 243 REE papers and 254 TEE papers identified, 21 and four studies, respectively, met the inclusion criteria. (1) The most accurate REE predictions varied with BMI subgroup: WHO (weight and height) ≥25 and ≥30 kg m−2; Mifflin 30-39.9 kg m−2; Henry ≥40 kg m−2. The most precise REE predictions were obtained using Mifflin in BMI 30-39.9 and ≥40 kg m−2, where approximately 75% of predictions were within 10% of measured REE. (2) No accurate or precise predictions of TEE were identified. Conclusions No single prediction equation provides accurate and precise REE estimates in all obese adults. Mifflin equations are recommended in this population, although errors exceed 10% in 25% of those assessed. There is no evidence to support the use of prediction equations in estimating TEE in obesity. [ABSTRACT FROM AUTHOR]

Social housing organisations are increasingly installing renewable energy technologies, particularly for the provision of heating and hot water. To meet carbon reduction targets, uptake and installation must allow occupants to use the technology effectively. This paper describes research which investigated the service of installing heat pumps into UK social housing properties, from both landlords’ and tenants’ experiences. Adopting a user centred design approach, the research was in three phases: an exploration study to investigate landlords’ and tenants’ experiences of heat pump installation and use; refinement and development of the requirements for improved service delivery, primarily technology introduction and control; and the development and initial evaluation of an information leaflet as a key touchpoint in the service delivery. Recommendations for improved service delivery, to enable heat pumps to be accepted and used more effectively, are presented, as well as reflection on the process of applying user centred design in this context. In a relatively immature area of industry, installations to date have been heavily focused on technical aspects. This paper provides an insight into the human aspects of the service delivery of heat pumps in social housing, providing designers and social housing landlords with insight about how to improve the service.

This paper explores the equity implications of a transition to a decentralised energy system in the UK. We base our analysis on one of three idealised transition pathways developed by the EPSRC-funded Realising Transition Pathways (RTP) project. Each pathway is characterised by a different mix of technologies, ownership and governance of the energy transition, and stretches from 2010 to 2050. In this paper we focus on the 'Thousand Flowers' (TF) pathway, which stipulates a much greater role for civil society in the energy system. Here, civil society actors are instrumental in delivering 50 per cent of final electricity demand from decentralised, low-carbon sources by 2050. Such a radical and systemic transition will require both institutional as well as technological change. The systemic institutional transformation necessary to support wide-spread adoption of community/decentralised energy schemes and the potential distributional impacts have, however, received limited attention to date. To address this gap, we draw on collected outputs of the RTP consortium and extant literatures on community and decentralised energy to explore potential institutional barriers and distributional impacts of the TF pathway. We argue a transition to a TF future would require significant institutional changes to UK energy governance, new municipal and community business models, and new financial and organisational structures in energy ownership. Second, widespread adoption of distributed energy sources would undermine the viability of traditional large power plants; leading to the need for new forms of state support to maintain assets at transmission level. Finally, we contend that expanded community energy provision has the potential to reproduce, or even exacerbate, existing socio-economic and spatial inequalities. [ABSTRACT FROM AUTHOR]

Over the past decade, a growing body of research has examined the role of cities in addressing climate change and the institutional and political challenges which they encounter. For the most part, in these accounts, the infrastructure networks, their material fabric, everyday practices and political economies, have remained unexamined. In this paper, it is argued that this is a critical omission and an approach is developed for understanding how urban responses to climate change both configure and are configured by infrastructure networks. Central to any such analysis is the conception of how and why (urban) infrastructure networks undergo change. Focusing on urban energy networks and on the case of London, the paper argues for an analysis of the ‘urban infrastructure regimes’ and ‘experiments’ through which climate change is governed. It is found that climate change experiments serve as a means through which dominant actors articulate and test new ‘low-carbon’ logics for urban infrastructure development. It is argued that experiments work by establishing new circuits, configuring actors in new sets of relations and through these means realising the potential for addressing climate change in the city. At the same time, experiments become sites of conflict, a means through which new forms of urban circulation can be confined and marginalised, leaving dominant energy regimes (relatively) intact.

The notion of ‘fuel poverty’, referring to affordable warmth, underpins established research and policy agendas in the UK and has been extremely influential worldwide. In this context, British researchers, official policymaking bodies and NGOs have put forward the notion of ‘transport poverty’, building on an implicit analogy between (recognised) fuel poverty and (neglected) transport affordability issues. However, the conceptual similarities and differences between ’fuel’ and ’transport’ poverty remain largely unaddressed in the UK. This paper systematically compares and contrasts the two concepts, examining critically the assumption of a simple equivalence between them. We illustrate similarities and differences under four headings: (i) negative consequences of lack of warmth and lack of access; (ii) drivers of fuel and transport poverty; (iii) definition and measurement; (iv) policy interventions. Our review suggests that there are important conceptual and practical differences between transport and domestic energy consumption, with crucial consequences for how affordability problems amongst households are to be conceptualised and addressed. In a context where transport and energy exhibit two parallel policy worlds, the analysis in the paper and these conclusions reinforce how and why these differences matter. As we embark on an ever closer union between our domestic energy and transport energy systems the importance of these contradictions will become increasingly evident and problematic. This work contributes to the long-term debate about how best to manage these issues in a radical energy transition that properly pays attention to issues of equity and affordability.

This paper gives a historical overview of the development of the U.K. marine energy sector from its academic beginnings in the early 1970s. It includes discussion on government support policies and where the sector might develop up to and beyond the end of this decade. The paper also presents two very different projects: the European Marine Energy Centre in Orkney, U.K., and the forthcoming All Waters Current and Wave Test Facility in Edinburgh, U.K., as examples of capital investment in the sector.

Purpose – The purpose of this paper is to valuate existing building stock with respect to its contribution to a changing and uncertain future, especially in relation to energy performance. Design/methodology/approach – The authors review literature related to existing buildings, climate change and future environmental needs; present energy performance data from ten case studies; and identify inadequacies and scope for improvements with reference to typical housing stock. Findings – Current policies and programmes are inadequate to the scope and scale of the task; a step-change in thought and practice is needed. Practical implications – A massive programme is warranted if the substantial stock of existing buildings is to be adapted to meet identified environmental standards to "save the planet"; a radical re-conceptualisation of building adaptation is required. Originality/value – The paper prompts a review of the role of the surveyor in achieving sustainability through adaptation of existing buildings. [ABSTRACT FROM AUTHOR]

Under the threat of the disruptions of climate change, there is growing interest in clean coal technology in the UK. This paper reviews the technologies underpinning the capture, transportation and storage of CO2. In the case of the UK, the storage of CO2 is planned in the sub seabed of the North Sea Continental Shelf. This being so, the paper goes on to analyse the rapid changes made at International, EU and UK level to shape a legal framework, the contours of which, if not the precise topography, is now visibly recognisable. It explores the linkages between regimes on climate change and marine protection and it concludes that the viability of the technology may ultimately be dependent on one element of that regulatory structure, namely the EU Emissions Trading Scheme since, ultimately, the price of carbon will determine levels of investment in the technology.

This paper examines the politics and the policy developments regarding access to electricity and water supply in Britain after the privatisation of these industries in 1990. It does this primarily through discussing two issues: paying for water and fuel poverty. It concludes that, somewhat surprisingly, the introduction of privatisation and greater reliance on market mechanisms has not made the material position of disadvantaged consumers worse as regards these industries. This seems to be attributable partly to changes in the regulatory structure consequent on privatisation and partly due to changes in national politics. [ABSTRACT FROM AUTHOR]

The governments of Britain, France, and the United States are seeking to promote renewed investment in nuclear power through metagovernance. Metagovernance describes the way governments can leverage state power and resources to shape the behavior of networked actors to advance policy goals. To metagovern, governments use a variety of policy tools but the factors shaping the design of these policy tools remains unclear. Grid-group cultural theory is used to show that the design of the policy tools used in metagovernance reflects both an underlying cultural bias within government and prevailing institutional circumstances. The paper demonstrates the utility of cultural theory in the study of metagovernance. [ABSTRACT FROM AUTHOR]

For daylight to make a real contribution to energy efficiency, appropriate control of electric lighting is essential. This paper outlines methods to predict electric lighting use for various different types of control, given internal daylight illuminances. Two different kinds of calculation are considered. Annual lighting use can be determined from yearly daylight data, usually in the form of a cumulative distribution. More sophisticated computer programs use hourly daylight data to give a continuous profile of lighting use and the consequent energy flows and environmental conditions within a building. For both types of application, appropriate algorithms are given to quantify the savings from various types of photoelectric and manual controls. Pour que la lumiere du jour apporte une reelle contribution au rendement energetique, il est essentiel de bien controler l'eclairage electrique. Cet article decrit brievement les methodes qui permettent de prevoir l'eclairage electrique utilise en fonction de differents types de controle, compte tenu de l'eclairement assure par la lumiere du jour interieure. Deux types differents de calcul sont pris en consideration. L'utilisation annuelle de l'eclairage peut etre determinee a partir des donnees annuelles relatives a la lumiere du jour, generalement sous la forme d'une distribution cumulative. Des programmes informatiques plus complexes utilisent des donnees horaires sur la lumiere du jour pour obtenir un profil continu de l'utilisation de l'eclairage ainsi que les flux d'energie correspondants et les conditions d'environnement d'un batiment. Les auteurs donnent pour deux types d'application des algorithmes appropries qui permettent de quantifier les economies correspondant a divers types de commandes photoelectriques et manuelles.

Fuel poverty is now widely recognised in the UK as a distinct form of social inequality and injustice, but exactly which energy-uses and services should be incorporated into conceptualisations of fuel poverty is rarely discussed explicitly. In this paper, we investigate how different energy-uses are portrayed as part of fuel poverty by national government and NGOs in the UK. We find that, to some degree, official definitions of fuel poverty in the UK include multiple energy-uses. However, this is not reflected in dominant policy and NGO discourses which predominantly frame fuel poverty as solely a lack of adequate space-heating. We conclude by discussing whether non-heating energy-uses and services should be more fully recognised and incorporated into fuel poverty discourses and policy measures, identifying two areas that warrant further research and debate.

Traditional buildings constitute a large proportion of the building stock in many countries worldwide; around 40% of the UK's housing stock was built before 1940 and was primarily made with solid masonry walls. Only 11% of UK solid-walled dwellings had insulation installed, suggesting the high potential of the low-carbon retrofit of traditional buildings. However, there is evidence of the occurrence of unintended consequences, often associated with excess moisture. A method is presented for moisture risk management that includes the development of a process and a framework. These tools are then integrated into a novel framework for the combined energy and moisture performance retrofit of traditional buildings. An example of the framework's practical application is provided, with a focus on retrofit measures for solid-wall insulation. The proposed systematic approach demonstrates the interconnected nature of energy and moisture. It harmonises the principles needed to support organisations in the delivery of robust retrofit of traditional buildings through the integration of pre-retrofit building assessment and post-retrofit monitoring in the process. The risk-management process and framework presented can be valuable tools to support designers in providing robust and scalable retrofit measures and strategies. [ABSTRACT FROM AUTHOR]

The health and performance of students and teachers are influenced by the internal environment of school buildings such as noise levels, indoor temperature, air quality and light. Providing good internal environmental conditions with minimum energy for schools has long been a concern in school design guidelines around the world. The growing necessity to save energy in an uncertain future and to provide a good indoor environment in schools suggests that school designers should approach design more holistically in order to offer a better internal environment and to reduce the gap between design and performance. This paper investigates design issues in UK schools through case study analysis and a review of the literature. The main reasons for these design issues can be attributed to the lack of optimisation of different internal environment factors and their relation with energy consumption; the lack of understanding occupants’ response to the environment; the lack of building adaptability and the inappropriate application or use technology. This paper urges school designers to look at these factors holistically in order to overcome these problems in the future design of UK schools. This study also suggests an Environmental Circle to look at the interrelation between comfort factors through their sub factors in a holistic manner in order to prevent any conflict between.

In the UK, it has become apparent in recent years that there is often a discrepancy between the steady-state predicted and the measured in situ thermal performance of the building fabric, with the measured in situ performance being greater than that predicted. This discrepancy or gap in the thermal performance of the building fabric is commonly referred to as the building fabric 'performance gap'. This paper presents the results and key messages obtained from undertaking a whole-building heat loss test (a coheating test) on seven new-build dwellings as part of the Technology Strategy Board's Building Performance Evaluation Programme. While the total number of dwellings involved in the work reported here is small, the results illustrate that a wide range of discrepancies in thermal performance was measured for the tested dwellings. Despite this, the results also indicate that it is possible to construct dwellings where the building fabric performs thermally more or less as predicted, thus effectively bridging the traditional building fabric performance gap that exists in mainstream housing in the UK.

The sophistication in the demand management approaches in both transport and energy sectors and their interaction call for modelling approaches that consider both sectors jointly. For agent-based microsimulation models of travel demand and energy consumption, this implies the necessity to ensure consistent representation of user behaviour with respect to mobility and energy consumption behaviours across the model components. Therefore this paper proposes a microeconomic framework, termed the HOT model (Home, Out-of-home, Travel) grounded in the goods-leisure paradigm, but extended to incorporate emerging activity-travel behaviour patterns and their energy consumption implications. We discuss how the model can be operationalised and embedded within agent-based frameworks with a case study using time use and energy consumption data from the UK. [ABSTRACT FROM AUTHOR]

The limited microeconometric evidence on the efficacy of environmental Negotiated Agreements (NAs) is an obstacle to both their introduction and effective design. We help fill this gap by providing evidence on the impact of the second Climate Change Agreements (CCAs) on business electricity consumption and employment. The CCAs are NAs offering a reduction on the Climate Change Levy (CCL), an energy consumption tax, in exchange for commitments to improve energy efficiency. We use the novel changes-in-changes method to account for heterogeneity in treatment effects. Our results indicate that the second CCAs yielded improved outcomes compared to the counterfactual of full CCL with an average reduction of − 4.81% in electricity consumption. They also reveal the importance of allowing for heterogeneity, as the impact on electricity consumption at the identified deciles varied between − 9.33 and 12.54%. This is a marked difference from the first CCAs which were found to increase consumption. The heterogeneity in treatment response is corroborated when extending the study to two large industrial sectors in the sample and when studying firms selecting differing target reporting methods. Confirming the findings from earlier studies of the first scheme, our results indicate a non-statistically significant reduction in employment, about − 4.6% on average, for the second CCAs.

UK energy policies position urban heat networks as components of a resilient low carbon, affordable system, but, as Stewart Russell's work showed, such technologies have never been integrated into UK provision. This paper takes Russell's legacy forward by examining prospects for urban district heating and combined heat and power development in the context of the financial, rather than technological, innovations shaped by liberalised energy and financial markets. Drawing on sociology of markets and social studies of finance, the paper examines the resulting evaluation practices. Findings indicate that such district energy infrastructure does not conform to the investment calculus, making a business case hard to establish. Bridging the value gap between liberalised finance and district energy requires actors willing to devise improvised solutions. In spite of the established sustainability credentials of the technology therefore, significant deployment in the UK (and similar countries) will depend on political leadership and new fiscal policy.

This paper investigates factors associated with variation in daily total (electricity and gas) energy consumption in domestic buildings using linked pre-COVID-19 smart meter, weather, building thermal characteristics, and socio-technical survey data covering appliance ownership, demographics, behaviours, and attitudes for two nested sub-samples of 1418 and 682 British households selected from the Smart Energy Research Laboratory (SERL) Observatory panel. Linear mixed effects modelling resulted in adjusted R2 between 63% and 80% depending on sample size and combinations of contextual data used. Increased daily energy consumption was significantly associated (p -value < 0.05, VIF < 5) with: households living in buildings with more rooms and bedrooms, that are older, more detached, have air-conditioning, and experience colder (more heating degree days) or less sunny weather; households with more adult occupants, more children, older adult occupants, higher heating temperature setpoints, and that do not try to save energy. The results demonstrate the value of smart meter data linked with contextual data for improving understanding of energy demand in British housing. Accredited UK researchers are invited to apply to access the data, which has recently been updated to include over 13,000 households from across Great Britain. This paper provides guidance on appropriate methods to use when analysing the data. [ABSTRACT FROM AUTHOR]
