The Energy Institute (EI) developed its first Energy Barometer survey in 2015 which aims to understand professionals’ views and opinions of energy priorities, policies and technologies. 543 UK energy professionals from across the energy sector were surveyed. Following the survey, 79% of UK energy professionals believe their sector is not effectively communicating with the public. This suggests there is an urgent need to better understand how to use surveys in a more methodological way. Developed in conjunction with the EI, this paper presents the Energy Barometer survey methodology and results to achieve a better understanding of UK energy professionals’ current perceptions and future priorities. The paper makes two contributions to enhance the UK's energy debate. First, it provides the first results in a longitudinal assessment of energy professionals’ views of energy policy issues and discusses the implications for future policymaking. Second, it identifies opportunities for Energy Barometer findings to feed into scenarios development. A comparison with other studies was undertaken. It has been shown that the views of professionals working across the sector are aligned with decentralised approaches to decarbonisation. In particular, professionals expect action from policymakers to coordinate, engage with and encourage investment in energy efficiency. - Highlights: • 543 UK energy professionals from across the energy sector were surveyed. • Aiming to better understand views and opinions of energy priorities, policies and technologies. • A comparison of the methodology and results with other studies was undertaken. • Considers contributions of results to energy system scenario development. • Identifies particular need for increased energy efficiency investment.

Energy, the UK and the European Community

The emphasis of effort in European energy policy should be placed on external relations rather than internal regulation. The divergence of the interests of the United States and Europe in energy policy will no longer allow Europe to depend on US initiative. The temporary relaxation of world oil markets has engendered unrealistic complacency. The European Community must develop its important role as a means whereby the member states can formulate common initiatives to press within international institutions. Strong presentation of interests externally has to be complemented by internal adaptation. The Community has at the moment few means of influencing the form and nature of energy investment. This paper proposes a fund of the order of Pound1 bn per annum to be used for the promotion of projects whose intrinsic benefits are not fully translated into commercial advantage and which need political stimulus. Such a Fund might be, but need not necessarily be, financed by a small levy on imported oil. The UK should present more aggressively the considerable benefits which accrue to the Community from UK resources. There is perhaps an opportunity to take a more extrovert view of the relationship between the UK and the continental gas transport systems. (author)

Strategy for energy policy in the UK

UK Energy Policy is leading the world in showing how governments can effectively respond to the now widely accepted challenges of security of supply, low-carbon generation and pragmatic implementation. Confidence in the UK as place to invest in new nuclear is very high-there are already 3 developers who have between them already invested over 1 billion, 5 sites are planned to be developed and between 10 and 12 new reactors are planned to be built. To be clear, this is by far the largest commitment to new nuclear in the Western World and swamps in other countries. This achievement is a combination of vision, continuity, political consensus and a group of ministers and officials who are clear in the goals for the long-term sustain ability of an energy policy that will dramatically affect the lives of many generations to come. Recognising the multi-generational obligations and consequences of government policy's key to ensuring that this investment continues, together with the maintenance of the trust that investors have developed in the management of energy policy by the UK government. There is no doubt in the commitment of the UK government to delivering the safe, secure and low-carbon energy future of the UK. The opportunities for businesses and high-quality job creation are undoubted-all that now has to happen is for developers, reactor vendors, construction companies and communities to show how they can together deliver the cheapest form of low-carbon base load to time and to cost and to the benefit of local communities and the UK economy. the world is watching for the UK to show how it can be done.

There is now emerging a consensus that the sensitive development of renewable sources of energy, and in particular wind energy, is going to be of major environmental significance for the UK. Primarily, renewable sources of energy can act as a means of combating the Greenhouse Effect and of reducing the other environmental impacts of conventional energy technology, including the build-up of radioactive waste and the damaging emissions from fossil fuelled power stations. The UK has a large natural potential for harnessing energy from the wind (between 20% and 200% of our current electrical requirements). This potential is beginning to be tapped. Wind energy is now in a position where it can take advantage of the profound changes taking place in the form of the privatisation of the Electricity Supply Industry. In other countries wind energy has developed successfully. (author).

The impact of energy price shocks on the UK economy

International Nuclear Information System (INIS)

2007-01-01

This report describes the results of six scenarios considering the impact of energy price shocks on the UK economy. The six scenarios considered are: UK aggregate energy price scenario; pan-Europe aggregate energy price; global aggregate energy price; UK temporary gas price; UK permanent gas price; crude (Brent) oil price. As expected, shocks to aggregate energy prices cause the largest macroeconomic and energy demand effects (in terms of growth rate volatility). Shocks to gas prices produce a greater growth volatility for macroeconomic and energy demand than shocks to oil prices. In general terms, shocks specific to the UK market tend to produce more growth rate volatility than wider ranging price shocks (global or pan-European). All of the price shocks considered have a recursive effect on the main indicators, which tend to stabilise around the baseline level in the long run. The report summarises the results obtained in the different scenarios

A summary is given of recent research into the potential for energy-conserving capital equipment in UK industries. The research had significant findings regarding the feasibility of achieving low-energy scenarios. It also stressed the importance of site specific factors in inhibiting incremental technical change such as that common in energy-conservation investments, developed a soft systems model of energy-management activities and investigated current progress and management styles in the brewing, malting, distilling and dairy sectors.

Sector review of UK higher education energy consumption

Ward, Ian; Ogbonna, Anthony; Altan, Hasim

2008-01-01

The UK education and education-related services are said to be one of the fastest-growing export earners in recent years and are known to have had significant impacts at the micro- and macro-levels of the UK. This review looks at energy consumption of this fast growing sector. It concentrates on the energy consumption patterns of the funded higher education institutions in the UK. The findings indicate energy consumption in the sector has been on the increase in the 6 years up to 2006; rising by about 2.7% above the 2001 consumption levels. This increase is, however, not evenly spread across the entire sector. The high energy-consuming institutions appear to be increasing their net consumption, relative to other institutions. Gross internal area, staff and research student full-time equivalent were found to have highest correlation with energy consumption across the sector and may be used as proxy indicators for energy consumption as well as the targets of interventions

The UK whole-wheat bioethanol and straw and DDGS-based combined heat and power (CHP) generation systems were assessed for environmental sustainability using a range of impact categories or characterisations (IC): cumulative primary fossil energy (CPE), land use, life cycle global warming potential over 100 years (GWP 100 ), acidification potential (AP), eutrophication potential (EP) and abiotic resources use (ARU). The European Union (EU) Renewable Energy Directive's target of greenhouse gas (GHG) emission saving of 60% in comparison to an equivalent fossil-based system by 2020 seems to be very challenging for stand-alone wheat bioethanol system. However, the whole-wheat integrated system, wherein the CHP from the excess straw grown in the same season and from the same land is utilised in the wheat bioethanol plant, can be demonstrated for potential sustainability improvement, achieving 85% emission reduction and 97% CPE saving compared to reference fossil systems. The net bioenergy from this system and from 172,370 ha of grade 3 land is 12.1 PJ y −1 providing land to energy yield of 70 GJ ha −1 y −1 . The use of DDGS as an animal feed replacing soy meal incurs environmental emission credit, whilst its use in heat or CHP generation saves CPE. The hot spots in whole system identified under each impact category are as follows: bioethanol plant and wheat cultivation for CPE (50% and 48%), as well as for ARU (46% and 52%). EP and GWP 100 are distributed among wheat cultivation (49% and 37%), CHP plant (26% and 30%) and bioethanol plant (25%, and 33%), respectively. -- Highlights: ► UK whole-wheat energy system can achieve 85% GHG emission reduction. ► UK whole-wheat energy system can achieve 97% primary energy saving. ► The land to energy yield of the UK whole-wheat system is 70 GJ ha −1 y −1 . ► Fertiliser production is the hotspot. ► DDGS and straw-based CHP system integration to wheat bioethanol is feasible

An investment-led approach to analysing the hydrogen energy economy in the UK

International Nuclear Information System (INIS)

Houghton, T.; Cruden, A.

2009-01-01

The authors propose an alternative, investment-led approach to analysing the potential for the development of hydrogen energy in the UK. The UK economy is relatively sensitive to movements in world fossil fuels markets since the energy sector contributes at least 5% of UK GDP and represents an asset pool of at least pound 230 billion. Much of the ongoing research to assess possible scenarios for the development of alternatives to existing energy systems, including hydrogen energy, in the UK is built around the cost-optimising MARKAL model. The authors believe that this approach offers an incomplete picture of hydrogen energy deployment since it ignores the mechanisms dictating the flow of commercial capital to the sector and they suggest an alternative model based on the risk-adjusted value proposition. Initial analysis shows that valuation differentials already exist between companies in the fossil fuel, utilities and fuel cell sectors and that this might be exploited to the advantage of investors thus affecting the speed of development in hydrogen energy. It should be noted that the following represents work in progress and the authors intend to publish an extended analysis in due course. (author)

2012-01-01

This paper reviews major studies in three traditional lines of research in residential energy consumption in the UK, i.e., economic/infrastructure, behaviour, and load profiling. Based on the review the paper proposes a three-dimensional model for archetyping residential energy consumers in the UK by considering property energy efficiency levels, the greenness of household behaviour of using energy, and the duration of property daytime occupancy. With the proposed model, eight archetypes of residential energy consumers in the UK have been identified. They are: pioneer greens, follower greens, concerned greens, home stayers, unconscientious wasters, regular wasters, daytime wasters, and disengaged wasters. Using a case study, these archetypes of residential energy consumers demonstrate the robustness of the 3-D model in aiding local energy policy/intervention design in the UK. - Highlights: ► This paper reviews the three traditional lines of research in residential energy consumption in the UK. ► Based on the literature review, the paper proposes a 3-D conceptual model for archetyping UK residential energy consumers. ► The 3-D archetype model can aid local energy policy/intervention design in the UK.

Assessment of environmental co-benefits of energy system decarbonisation - the case of UK air quality using Remote Sensing and Model simulations

Science.gov (United States)

Sobral Mourao, Z.; Konadu, D. D.; Damoah, R.

The UK has a binding obligation to reduce GHG emission by 80% (based on 1990 levels) by 2050. Meeting this target requires extensive decarbonisation of the UK energy system. Different pathways that achieve this target at the lowest system costs are being explored at different levels of policy and decisions on future energy infrastructure. Whilst benefits of decarbonisation are mainly focused on the impacts on climate change, there are other potential environmental and health impacts such as air-quality. In particular, a decrease in fossil fuel use by directly substituting current systems with low-carbon technologies could lead to significant reductions in the concentrations of SO2, NOX, CO and other atmospheric pollutants. So far, the proposed decarbonisation pathways tend to target the electricity sector first, followed by a transition in transport and heating technologies and use. However, the spatial dimension of where short term changes in the energy sector occur in relation to high density population areas is not taken into account when defining the energy transition strategies. This may lead to limited short-term improvements in air quality within urban areas, where use of fossil fuels for heating and transport is the main contribution to overall atmospheric pollutant levels. It is therefore imperative to explore decarbonisation strategies that prioritise transition in sectors of the energy system that produce immediate improvements in air quality in key regions of the UK. This study aims to use a combination of Remote Sensing observations and atmospheric chemistry/transport modelling approaches to estimate and map the atmospheric pollutants impact of the traditional approach of decarbonising electricity first compared to a slower transition in the electricity sector, but faster change in end use sectors (heating and transport). This would provide an additional standard to compare future energy system pathways beyond the traditional metrics of cost and GHG

The deployment of decentralised energy systems as part of the housing growth programme in the UK

International Nuclear Information System (INIS)

Williams, Jo

2010-01-01

The housing growth programme could offer an opportunity for accelerating the deployment of decentralised renewable energy systems (DRES) in the UK. The Government hopes to leverage private sector investment into DRES as part of new housing projects. The aim of this paper is to assess whether current regulatory and funding frameworks are sufficient to achieve this. The question is explored by drawing on the experience of developers, local authorities, energy utilities and service companies operating in the largest housing growth region in the UK-Thames Gateway. Their experience suggests that the current low intervention approach will be insufficient to generate the shift required in both industries. In order to be more successful economic and regulatory instruments should focus on producers (house-builders and energy providers) rather than consumers (households). Tighter regulation is needed to ensure that producers have a responsibility to install DRES as part of new developments, to enable connection to the grid, to ensure a sustained financial return from investment and revenue is spent on the expansion of new renewable energy infrastructure. This regulatory framework must be under-pinned by substantial funds focused on producers. Greater intervention is needed if DRES is to be included in new housing development.

Developing pathways for energy storage in the UK using a coevolutionary framework

Taylor, Peter G.; Bolton, Ronan; Stone, Dave; Upham, Paul

2013-01-01

A number of recent techno-economic studies have shown that energy storage could offer significant benefits to a low-carbon UK energy system as it faces increased challenges in matching supply and demand. However, the majority of this work has not investigated the real-world issues affecting the widespread deployment of storage. This paper is designed to address this gap by drawing on the systems innovation and socio-technical transitions literature to identify some of the most important contextual factors which are likely to influence storage deployment. Specifically it uses a coevolutionary framework to examine how changes in ecosystems, user practices, business strategies, institutions and technologies are creating a new selection environment and potentially opening up the energy system to new variations of storage for both electricity and heat. The analysis shows how these different dimensions of the energy regime can coevolve in mutually reinforcing ways to create alternative pathways for the energy system which in turn have different flexibility requirements and imply different roles for storage technologies. Using this framework three pathways are developed – user led, decentralised and centralised – which illustrate potential long-term trajectories for energy storage technologies in a low-carbon energy system. - highlights: • Energy storage can play a significant role in a low carbon UK energy system. • Changes in the selection environment will impact its deployment. • Several different deployment pathways are possible. • Its precise role is still subject to considerable uncertainty

Environmental aspects of large-scale wind-power systems in the UK

Robson, A.

1984-11-01

Environmental issues relating to the introduction of large, MW-scale wind turbines at land-based sites in the UK are discussed. Noise, television interference, hazards to bird life, and visual effects are considered. Areas of uncertainty are identified, but enough is known from experience elsewhere in the world to enable the first UK machines to be introduced in a safe and environementally acceptable manner. Research to establish siting criteria more clearly, and significantly increase the potential wind-energy resource is mentioned. Studies of the comparative risk of energy systems are shown to be overpessimistic for UK wind turbines.

It is argued that in the UK there is a lack of appreciation of the potential of solar energy at both government and public level. It is claimed that the government has made insufficient effort to stimulate the solar energy sector and provided little support for research: the UK solar market is therefore underdeveloped and systems are expensive. A survey to identify the reasons for the lack of awareness of solar potential, and how this might be rectified was carried out. The survey identified four particular points: (i) how to make solar energy more attractive to consumers, (ii) initiatives for Local Authorities, (iii) availability and quality of information from Energy Advice Centres and Local Authorities and (iv) actions to make Local Authorities more pro-active

Jones, E.; Leach, M.

2000-01-01

Residential energy use accounts for approximately 28 per cent of total primary energy use in the UK, with consumption in this sector forecast to increase due partly to expanding numbers of households. Finding ways to reduce residential energy consumption must form a key part of the climate change strategies of the UK and all developed countries. In 1995, an innovative piece of legislation was passed in the UK, devolving residential energy efficiency responsibility to local government. Under 'The Home Energy Conservation Act' (HECA), local authorities are obliged to consider the energy efficiency of private as well as public housing stock. Authorities were given a duty to produce a strategy for improving residential energy efficiency in their area by 30 per cent in the next 10-15 years. This paper describes the enormous variation in the quality of local authorities' strategies and discusses reasons for this variation. Based on a nationwide survey of HECA lead officers, it considers the opportunities and constraints facing local authorities, and what has been achieved to-date under the Act. It also examines how HECA fits into the UK's national energy policy and explains the roles of other institutions across the public, private and voluntary sector in facilitating implementation of the Act. Finally, the paper considers how other countries can learn from the UK's HECA experience and can use the Act as a template to apply the principle of subsidiarity to this area of environmental policy.

Wind energy - environmental impact assessment: the UK experience and the EU perspective

International Nuclear Information System (INIS)

Holmes, S.C.

1997-01-01

Planning systems play a critical role in the deployment of wind turbines. Wind energy developers in the UK are familiar with the plan-led system in which the acceptability of each development is determined by balancing local environmental impact with the benefits of the proposed scheme. This contrasts with the position in much of Northern Europe where development plants have the status of law, and wind farm development may take place only in areas identified in the Local Plan. In much of Southern Europe inconsistent implementation of national law tends to be a feature of planning systems. This paper will compare policies and practices in the planning systems of the UK and mainland Europe, north and south, and examine the consequences for wind energy development. Particular attention will be paid to the role of environmental assessment and to the wide variations between requirements placed on developers in individual member states to fund and prepare environmental statements. Factors which either encourage or hinder wind energy will be highlighted and consideration given to the impact of planning constraints on the European Untion wind market growth rate and its ultimate potential.

New nuclear power in the UK: A strategy for energy security?

International Nuclear Information System (INIS)

Watson, Jim; Scott, Alister

2009-01-01

The aim of this paper is to explore the extent to which the construction of new nuclear power plants in the UK can safeguard or enhance energy security. The paper starts with a discussion of energy security, and breaks it down into four main categories of threat. These include threats due to fossil fuel scarcity and external disruptions, problems due to a lack of investment in infrastructure, threats due to technology or infrastructure failure, and risks due to domestic activism or terrorism. The paper then discusses one of the most common strategies put forward to improve security-the promotion of diversity within energy systems. Following this, the paper assesses the potential for new nuclear investment to ameliorate security threats in each of the four categories introduced earlier in the paper. The paper concludes that whilst nuclear investment can help to mitigate some threats to UK energy security, the government's case for supporting this investment ignores some equally important security issues. As a result, the energy security case for nuclear power has not yet been made.

Renewable energy policy in the UK 1990-2003

International Nuclear Information System (INIS)

Mitchell, Catherine; Connor, Peter

2004-01-01

The UK's renewable energy policy has been characterised by opportunism, cost-limiting caps and continuous adjustments resulting from a lack of clarity of goals. Renewable electricity has had a specific delivery mechanism in place since 1990. The Non-Fossil Fuel Obligation (NFFO) did not deliver deployment; did not create mentors; did not promote diversity; was focussed on electricity and was generally beneficial only to large companies. A new support mechanism, the Renewable Obligation, began in April 2002. This may result in more deployment than the NFFO, but is also beneficial to electricity-generating technologies and large, established companies only. The UK Government published a visionary energy policy in early 2003 placing the UK on a path to cutting carbon dioxide emissions by 60% in 2050. This paper argues that unless the Government 'learns' from it's past results, mistakes and difficulties, clarifies the reasons for supporting renewable energy and then follows through with a focussed policy aimed at delivery, diversity and the creation of mentors, it is likely to be no more successful than the previous 13 years of renewable policy

Detailed oil and gas proposals in UK energy review

International Nuclear Information System (INIS)

2006-01-01

The UK government is proposing a four-pronged attack to try and sustain future oil and gas production from the UK with measures designed to coerce and encourage maximum exploitation of reserves under the Energy Review proposals. Tax is to be looked at again. There will also be a move towards web-based licence awards to speed up the licensing process for oil and gas exploration blocks; an infrastructure task force in the West of Shetlands region is planned, and the Stewardship initiative will be refocused. The 218-page Energy Review policy document says: 'Using regulatory powers if necessary, Government must press for full investment in fields that are already producing. We will immediately refocus the DTI's Stewardship initiative - on maintaining reliability and encouraging nearby exploration and should see results in these areas by the middle of next year.' Turning to the plans for a taskforce, the Energy Review announces: 'We are establishing a Taskforce with Industry to get the right infrastructure (for example pipelines) in place to the west of Shetland so that, with minimal impact to the environment, we can speed up development and exploration in the area. The Taskforce will report by the end of the year.' Also the Department of Trade and Industry will re-examine the UK's licensing regime, as part of a policy for 'Ensuring the development of a dynamic market fit for the future.' On this point, the government says: 'The commercial framework needs to change so that it encourages the industry to be dynamic in the future by facilitating a strong market in assets and rapid access to infrastructure. For example, the DTI is moving to a web-based system of licence assignments that will substantially speed up deal making and reduce costs, especially for smaller firms. We will also continue to build on the work of PILOT to secure the long-term future of the industry in the UK.' And on tax: 'It is vital to ensure that we have the right fiscal approach,' the government

The application of contrast explanation to energy policy research: UK nuclear energy policy 2002–2012

International Nuclear Information System (INIS)

Heffron, Raphael J.

2013-01-01

This paper advances the application of the methodology, contrast explanation, to energy policy research. Research in energy policy is complex and often involves inter-disciplinary work, which traditional economic methodologies fail to capture. Consequently, the more encompassing methodology of contrast explanation is assessed and its use in other social science disciplines explored in brief. It is then applied to an energy policy research topic—in this case, nuclear energy policy research in the UK. Contrast explanation facilitates research into policy and decision-making processes in energy studies and offers an alternative to the traditional economic methods used in energy research. Further, contrast explanation is extended by the addition of contested and uncontested hypotheses analyses. This research focuses on the methods employed to deliver the new nuclear programme of the UK government. In order to achieve a sustainable nuclear energy policy three issues are of major importance: (1) law, policy and development; (2) public administration; and (3) project management. Further, the research identifies that policy in the area remains to be resolved, in particular at an institutional and legal level. However, contrary to the literature, in some areas, the research identifies a change of course as the UK concentrates on delivering a long-term policy for the nuclear energy sector and the overall energy sector. - Highlights: ► Energy policy research is interdisciplinary and needs additional methodological approaches. ► New method of contrast explanation advanced for energy policy research. ► This methodology is based on dialectical learning which examines conflict between sources of data. ► Research example used here is of UK nuclear energy policy. ► Major issues in UK nuclear energy policy are planning law, public administration, and project management

UK energy 1970-2000: facts and fantasies

Lehmann, P.J.; Hough, D.W.

1983-01-01

This paper sets out a central view of future UK energy and contrasts the small changes which are foreseen with the radical developments of the last 10 years. It therefore asks how wrong the central view could be, and sketches out some alternative fantasies of what might happen - extensive conservation and energy surplus; complacency and energy crisis; more work from home and possible decentralization of energy supplies. Finally, it describes some of the applications within the gas industry of long-term views about energy. (author)

UK's energy strategy: how to reconcile low-carbon policy and energy independence

International Nuclear Information System (INIS)

2014-01-01

From a global energy point of view, UK will be confronted with the shutdown of 20% of its electricity production capacity (decommissioning of old coal-fired or nuclear power plants), but also to the collapse of its domestic natural gas production, leading to an increased dependence to raw material imports. The foreseeable consequence is a degradation of UK's balance of trade and security of supply (geopolitical risks)

Energy strategies for the UK

Littlechild, S.C.; Vaidya, K.G.

1982-01-01

This book provides the first comprehensive and integrated model of the UK energy sector which focuses on decision-making and optimisation rather than on forecasting or simulation. It incorporates the production and investment policy of all the major fuels (coal, oil, gas and electricity) over a fifty year horizon and analyses strategy under a variety of different assumptions about costs, demands, technolgy and future decisions. The authors cover the wide spectrum of energy problems and policy, including scenarios of rising il and gas prices, and there are striking calculations of the (low) costs of a non-nuclear plus conservation strategy.

Soft-linking energy systems and GIS models to investigate spatial hydrogen infrastructure development in a low-carbon UK energy system

International Nuclear Information System (INIS)

Strachan, Neil; Hughes, Nick; Balta-Ozkan, Nazmiye; McGeevor, Kate; Joffe, David

2009-01-01

This paper describes an innovative modelling approach focusing on linking spatial (GIS) modelling of hydrogen (H 2 ) supply, demands and infrastructures, anchored within a economy-wide energy systems model (MARKAL). The UK government is legislating a groundbreaking climate change mitigation target for a 60% CO 2 reduction by 2050, and has identified H 2 infrastructures and technologies as potentially playing a major role, notably in the transport sector. An exploratory set of linked GIS-MARKAL model scenarios generate a range of nuanced insights including spatial matching of supply and demand for optimal zero-carbon H 2 deployment, a crucial finding on successive clustering of demand centres to enable economies of scale in H 2 supply and distribution, the competitiveness of imported liquid H 2 and of liquid H 2 distribution, and sectoral competition for coal with carbon sequestration between electricity and H 2 production under economy-wide CO 2 constraints.

Recent trends and future opportunities in UK bioenergy: Maximising biomass penetration in a centralised energy system

International Nuclear Information System (INIS)

Perry, Miles; Rosillo-Calle, Frank

2008-01-01

In the past decade or so, the British government policy support for renewable energy (RE) has been at the core of the rapid growth of bioenergy in the UK rather than genuine market forces. Policy support has been through various instruments which are discussed in this paper, with particular attention given to co-firing and transport fuels. The UK energy sector remains dominated by large fossil fuels power plants and this does not facilitate the introduction of RE. One exception is co-firing which in 2005 generated 2.5 TWh. Another area of considerable potential and interest is the use of biofuels (biodiesel and bioethanol) for transport, although current contribution remains still very small (0.18% of total fuel sales in 2005). In 2005, the UK used 1.4 million tonnes of biomass in co-firing, mostly imported, while considerable potential exists for further expansion should policy incentives continue. It is also generally accepted that the UK will have to rely largely on imports if it is to fulfil its 5% minimum biofuel blends agreed for 2010 and 10% in 2015. Both sectors present excellent opportunities for international bioenergy trade, despite the domestic production potential, as demonstrated in this paper. In addition, the forthcoming introduction of carbon and sustainability reporting should incentivise greater reporting along the supply chain, encouraging trade in the most sustainable biofuels.

UK energy policy – Stuck in ideological limbo?

International Nuclear Information System (INIS)

Keay, Malcolm

2016-01-01

Energy policy in the UK has undergone a paradigm change over recent decades – from the free market stance of the 1990s to the more interventionist measures of the 21st century. However, the two approaches have not been reconciled – even as the Government intervenes, it reaffirms its goal of creating more competitive markets. The contradictions are most apparent with electricity, which has been the main focus of intervention to date, in line with decarbonisation strategy. Investment is dependent on Government support, which changes in response to circumstances, creating uncertainty and undermining the basis of market operation – so leading to the need for more intervention. The future for other sources – natural gas, nuclear power and carbon capture and storage in particular – remains unclear. The Government risks getting the worst of both worlds – without the coordination and direction which could come from a centralised approach or the efficiencies and innovation which might emerge from a more consistent market based policy. Unless a fuller policy statement, expected later this year, can clarify matters, UK energy policy will not be fit for purpose and will fail to meet its key goals, of economic effectiveness, environmental protection and energy security. - Highlights: •UK energy policy has undergone a partial paradigm change. •Electricity has been the main focus of intervention to date, leading to distortions. •The way forward in other sectors is uncertain. •Key energy policy goals are at risk. •The Government needs to develop a clearer strategy.

Energy UK 2011? Give us just a little more time

Energy Technology Data Exchange (ETDEWEB)

Darkwa, K.; O`Callaghan, P.W. [Nottingham Trent University, Nottingham (United Kingdom). Faculty of Environmental Studies

1995-04-01

The article analyses the trends from `published proved` fossil reserves, consumption and lives, both in the UK and globally. Despite fears of global warming, and the 1988 Toronto Protocol, energy consumption rates globally have increased 25% over the past two decades. And although they fluctuate, UK rates have not declined significantly. In the absence of imports UK indigenous fossil fuels will be depleted in 2011. The UK has vast reserves of coal, shale oil and peat, but is currently unable to complete with cheap imported fuel. The authors urge continuous review of the economic, political and social factors. 1 fig., 1 tab.

Evaluating biomass energy strategies for a UK eco-town with an MILP optimization model

Keirstead, James; Samsatli, Nouri; Pantaleo, A. Marco; Shah, Nilay

2012-01-01

Recent years have shown a marked interest in the construction of eco-towns, showcase developments intended to demonstrate the best in ecologically-sensitive and energy-efficient construction. This paper examines one such development in the UK and considers the role of biomass energy systems. We present an integrated resource modelling framework that identifies an optimized low-cost energy supply system including the choice of conversion technologies, fuel sources, and distribution networks. Our analysis shows that strategies based on imported wood chips, rather than locally converted forestry residues, burned in a mix of ICE and ORC combined heat and power facilities offer the most promise. While there are uncertainties surrounding the precise environmental impacts of these solutions, it is clear that such biomass systems can help eco-towns to meet their target of an 80% reduction in greenhouse gas emissions. -- Highlights: ► An optimization model for urban biomass energy system design is presented. ► Tool selects technologies, operating rates, supply infrastructures. ► Five technology scenarios evaluated for a UK eco-town proposal. ► Results show ICE and ORC CHP units, fed by wood chips, promising. ► Results show biomass can help eco-towns achieve 80% GHG emission reductions.

Highlights: • Results of an EES system demonstration project carried out in the UK. • Approaches to the design of trials for EES and observation on their application. • A formalised methodology for analysis of smart grids trials. • Validated models of energy storage. • Capability of EES to connect larger quantities of heat pumps and PV is evaluated. - Abstract: The UK government’s CO 2 emissions targets will require electrification of much of the country’s infrastructure with low carbon technologies such as photovoltaic panels, electric vehicles and heat pumps. The large scale proliferation of these technologies will necessitate major changes to the planning and operation of distribution networks. Distribution network operators are trialling electrical energy storage (EES) across their networks to increase their understanding of the contribution that it can make to enable the expected paradigm shift in generation and consumption of electricity. In order to evaluate a range of applications for EES, including voltage control and power flow management, installations have taken place at various distribution network locations and voltage levels. This article reports on trial design approaches and their application to a UK trial of an EES system to ensure broad applicability of the results. Results from these trials of an EES system, low carbon technologies and trial distribution networks are used to develop validated power system models. These models are used to evaluate, using a formalised methodology, the impact that EES could have on the design and operation of future distribution networks

Behavioural responses to photovoltaic systems in the UK domestic sector

International Nuclear Information System (INIS)

Keirstead, James

2007-01-01

Microgeneration - the generation of electricity and/or heat within the home - has recently become a notable addition to UK energy policy debates. Specifically research has suggested that, as well as providing renewable energy, these technologies might encourage changes in household energy consumption. The research presented here investigates this 'double-dividend' effect using PV households in the UK. It is shown that the installation of PV encouraged households to reduce their overall electricity consumption by approximately 6% and shift demand to times of peak generation. From a household perspective, system performance monitors had the most notable influence on these behavioural responses; however evolving industry arrangements for metering and microgeneration tariffs will be central in determining the future role of consumers. The paper therefore concludes that the full benefits of microgeneration can only be realised if informed households are integrated within supportive industry and government frameworks. (author)

A thousand flowers blooming? An examination of community energy in the UK

International Nuclear Information System (INIS)

Seyfang, Gill; Park, Jung Jin; Smith, Adrian

2013-01-01

Community energy has been proposed as a new policy tool to help achieve the transition to a low-carbon energy system, but the evidence base for this strategy is partial and fragmented. We therefore present new empirical evidence from the first independent UK-wide survey of community energy projects. Our survey investigates the objectives, origins and development of these groups across the UK, their activities and their networking activities as a sector. We also examine the strengths and weaknesses of these groups, along with the opportunities and threats presented by wider socioeconomic and political contexts, in order to improve understanding of the sector's potential and the challenges it faces. We highlight several key issues concerning the further development of the sector. First, this highly diverse sector is not reducible to a single entity; its multiple objectives need joined-up thinking among government departments. Second, its civil society basis is fundamental to its success at engaging local communities, and makes the sector quite distinct from the large energy companies these community groups are aiming to work alongside. There are inherent tensions and vulnerabilities in such a model, and limits to how much these groups can achieve on their own: consistent policy support is essential. - Highlights: • The community-led sustainable energy sector is diverse, and growing in the UK. • Sometimes it is more about the community than the energy. • Joined-up policy thinking is needed to properly measure performance and impact. • There are limits to how much civil society-led groups can achieve on their own. • Consistent policy support is essential to the sector's development

Benchmarking urban energy efficiency in the UK

International Nuclear Information System (INIS)

Keirstead, James

2013-01-01

This study asks what is the ‘best’ way to measure urban energy efficiency. There has been recent interest in identifying efficient cities so that best practices can be shared, a process known as benchmarking. Previous studies have used relatively simple metrics that provide limited insight on the complexity of urban energy efficiency and arguably fail to provide a ‘fair’ measure of urban performance. Using a data set of 198 urban UK local administrative units, three methods are compared: ratio measures, regression residuals, and data envelopment analysis. The results show that each method has its own strengths and weaknesses regarding the ease of interpretation, ability to identify outliers and provide consistent rankings. Efficient areas are diverse but are notably found in low income areas of large conurbations such as London, whereas industrial areas are consistently ranked as inefficient. The results highlight the shortcomings of the underlying production-based energy accounts. Ideally urban energy efficiency benchmarks would be built on consumption-based accounts, but interim recommendations are made regarding the use of efficiency measures that improve upon current practice and facilitate wider conversations about what it means for a specific city to be energy-efficient within an interconnected economy. - Highlights: • Benchmarking is a potentially valuable method for improving urban energy performance. • Three different measures of urban energy efficiency are presented for UK cities. • Most efficient areas are diverse but include low-income areas of large conurbations. • Least efficient areas perform industrial activities of national importance. • Improve current practice with grouped per capita metrics or regression residuals

Energy conservation and carbon emissions reduction are ways of mitigating the damage caused to the environment as a result of greenhouse gas emissions. All activities that consume energy also produce carbon dioxide (CO2), which, in turn, contributes to greenhouse gas emissions. Energy use in buildings accounts for 40-50% of the UK's CO2 emissions, and the residential sector contributes more than half of these emissions.\\ud The Climate Change Act (2008) has committed to reducing the UK's curre...

Reducing carbon emissions through improved household energy efficiency in the UK

International Nuclear Information System (INIS)

Ekins, P.; Hargreaves, C.

2002-01-01

A number of schemes to increase household energy efficiency have operated in the UK over the last 5-10 years. This paper evaluates their effectiveness in terms of reducing household energy use, carbon emissions and fuel poverty. It then draws on the quantitative results of these schemes, and published plans for their continuation, to model an extended and expanded Household Energy Efficiency Scenario to 2020, using an integrated economy-energy-environment model of the UK. The results suggest that while such schemes can play a significant role in reducing carbon emissions from households, much more ambitious schemes than those currently implemented will be necessary to offset the underlying growth in these emissions. Finally, the results are compared with the UK government's own estimates, in its Climate Change Programme, of carbon emission reductions from such schemes to 2010. The paper concludes that the government's estimates are somewhat optimistic, and that it will need substantial new policy measures beyond those already announced if its carbon reduction targets in this area are to be met.

Stuck between a ROC and a hard place? Barriers to the take up of green energy in the UK

International Nuclear Information System (INIS)

Diaz-Rainey, Ivan; Ashton, John K.

2008-01-01

This paper examines the UK mechanisms for ensuring future investment in renewable energy through consumer adoption of green energy tariffs and the Renewable Obligation Certificate (ROC) system. Using a national survey and focus groups the stated willingness by UK customers to pay a premium for renewable or green energy and actual take up of such tariffs is assessed. Substantial differences between willingness to pay for and the adoption of green energy tariffs are reported. This disparity is linked to a range of factors including consumer confusion, lack of supply, complexities of constructing 'green source' tariffs under the ROC system and a lack of customer trust. It is concluded that the re-definition of the green energy market in favour of 'green source' tariffs, greater direct compliance with the Renewable Obligation by addressing supply constraints, and efforts in providing clearer information and choices for consumers via a compulsory green energy accreditation scheme are required if willing consumers' are to contribute to investment in renewable energy

With relation to the petroleum substitution energy in the U.K., the paper states measures taken for the development and introduction and the state of spread. Introduced were the U.K., energy policy described by energy field, petroleum and natural gas, coal, nuclear power, electric power, renewable energy (petroleum substitution energy), and the policy on energy conservation and the recent trend. Further, the paper took up the environmental policy relating to global warming which is an environmental problem in close connection with the energy industry and described the present status of exhaust gas such as acid rain gas and ozonospherial destruction gas, target for reduction of exhaust gas, and the present situation of exhaust gas at power plant. Explained were the positioning of and the measures for the petroleum substitution energy which was incorporated into a part of the energy policy in the U.K., especially the recent trend of obligation to use non-fossil fuel. First, the order of priority of the governmental policies was introduced, and then the NFFO order was described which was to give reliable fund base to the development toward the practical use of petroleum substitution energy. The paper also commented on recent topics on the state of the practical use of petroleum substitution energy. 2 figs., 7 tabs.

The UK international participation is mainly at CERN although some British high energy physicists work at DESY in Germany, the Fermi Laboratory in the USA and, indeed, elsewhere as well. The UK subscription to CERN is 16% of the budget. The present state of high energy physics at CERN is summarized and the building of LEP explained. The Group's recommendations are that the UK's financial contribution to CERN should continue until LEP is built (by the early 1990s) but should then, because of the prevailing financial climate gradually be reduced by 25%.

The case for a new energy research, development and promotion policy for the UK

International Nuclear Information System (INIS)

Jamasb, Tooraj; Nuttall, William J.; Pollitt, Michael

2008-01-01

This paper is a critical assessment of the current balance of efforts towards energy research and development (R and D) and the promotion of low-carbon electricity technologies in the UK. We review the UK's main technological options and their estimated cost ranges in the medium term. We contrast the energy R and D spending with the current and expected future cost of renewable promotion policies and point out the high cost of carbon saving through existing renewable promotion arrangements. We also note that liberalisation of the electricity sector has had significant implications for the landscape of energy R and D in the UK. We argue that there is a need for reappraisal of the soundness and balance of the energy R and D and renewable capacity deployment efforts towards new energy technologies. We suggest that the cost-effectiveness of UK deployment policies needs to be more closely analysed as associated costs are non-trivial and expected to rise. We also make a case for considering increasing the current low level of energy R and D expenditure. Much of energy R and D is a public good and we should consider whether the current organisation of R and D effort is fit for purpose. We argue that it is important to build and maintain the research capability in the UK in order to absorb spillovers of technological progress elsewhere in the world. Against this background, the recent signs that an energy R and D renaissance could be underway are therefore positive and welcome

The role of gas infrastructure in promoting UK energy security

International Nuclear Information System (INIS)

Skea, Jim; Chaudry, Modassar; Wang Xinxin

2012-01-01

This paper considers whether commercially driven investment in gas infrastructure is sufficient to provide security of gas supply or whether strategic investment encouraged by government is desirable. The paper focuses on the UK in the wider EU context. A modelling analysis of the impact of disruptions, lasting from days to months, at the UK's largest piece of gas infrastructure is at the heart of the paper. The disruptions are hypothesised to take place in the mid-2020s, after the current wave of commercial investments in storage and LNG import facilities has worked its way through. The paper also analyses the current role of gas in energy markets, reviews past disruptions to gas supplies, highlights current patterns of commercial investment in gas infrastructure in the UK and assesses the implications of recent EU legislation on security of gas supply. The paper concludes with an analysis of the desirability of strategic investment in gas infrastructure. - Highlights: ► We examine the impact of disruptions to gas supplies on UK energy markets. ► The policy implications of the EU regulation on gas security are discussed. ► We investigate the role of gas infrastructure investment in mitigating gas shocks. ► The policy case for strategic investment in gas storage is assessed.

Factors determining the UK's back-end nuclear fuel cycle strategy and future nuclear systems

International Nuclear Information System (INIS)

Dunn, M.J.; Ainsworth, Z.E.

2002-01-01

Nuclear generating capacity in the UK is static with no units currently under construction. The AGRs and the UK's only PWR, Sizewell B, are operated by British Energy Generation Ltd (BEGL) and British Energy Generation (UK) Ltd (BEG(UK)L), who are subsidiaries of British Energy plc (BE) which was privatised in July 1996. Ownership of the Magnox stations, which were excluded from this privatisation, has now been transferred to BNFL.Government policy on spent fuel management in the UK is that it is for the owners of the spent fuel to decide on the appropriate spent fuel management options, based on their own commercial judgement, subject to meeting the necessary regulatory requirements. The main factors which have predominantly determined UK utility decisions on spent fuel management, to date, have been based on the technical considerations of the spent fuel characteristics, economic attractiveness of the options and at reactor site spent fuel storage capacities. To date, reprocessing has been the dominant form of spent fuel treatment in the UK. Spent fuel storage facilities consist of a mixture of at-reactor stores and large, centralised ponds associated with the reprocessing activities which take place at the Sellafield site. BEGL and BEG(UK)L have contracts for the lifetime arisings of AGR fuel which allow for all AGR spent fuel to be sent to Sellafield for reprocessing or long-term storage. The prompt reprocessing of all Magnox fuel will continue, and spent PWR fuel will continue to be stored at the reactor site in the short to medium term. It is likely that a combination of factors, which are discussed later in this paper, will continue to affect back-end nuclear fuel cycle strategy and future nuclear systems. (author)

The implications of an increasingly decentralised energy system

International Nuclear Information System (INIS)

Wolfe, Philip

2008-01-01

The UK government has signalled that the increasing use of decentralised energy forms part of its plan to achieve the UK's contribution to the EU's sustainable energy targets. Much of the technology for decentralised energy already exists, although it is not widely used in the UK. There will be need for new developments in onsite energy production, and in the delivery, integration and regulatory infrastructure to support it. Other State of Science reviews for this project describe particular energy technologies, but this paper highlights selected developments in thermal technologies and in biological processes which offer the potential for breakthroughs in converting biomass to energy. The effectiveness and deployment of decentralised energy can be enhanced by systems and infrastructure technology, not just for electricity but also in heat and biogas networks. Such systems are expected to be a focus of rapid development over the next two decades. Opportunities exist particularly in active networks, smart metering and intelligent tariff-interactive load management. Substantial regulatory and policy reform will be required to optimise the potential for onsite energy generation and effective two-way interchanges with centralised energy systems. There will be need for a regulatory system for heat networks and appropriate incentives for active networks. The development of an energy services business model in the industry will not progress until the compensation model changes to make it viable. The strength of the drivers for a trend towards decentralised energy, coupled with a wide range of scientific developments, should make this a very dynamic sector and present a host of new opportunities for British technology

Macroeconomic effects of efficiency policies for energy-intensive industries: the case of the UK Climate Change Agreements, 2000-2010

International Nuclear Information System (INIS)

Barker, T.; Foxon, T.

2007-01-01

This paper reports a study modeling the UK Climate Change Agreements (CCAs) and related energy-efficiency policies for energy-intensive industrial sectors. Bottom-up estimates of the effects of these policies are introduced into the energy-demand equations of a top-down dynamic econometric model of the UK economy with fifty industrial sectors, MDM-E3. This allowed estimation of the effects of the reduced energy use for the outputs from the sectors, i.e. the reductions in unit costs of the energy-intensive industries, on the demand for their outputs (both in the UK and in the export markets). The model is solved as a counterfactual 2000-2005 and as a projection 2005-2010 in a series of scenarios to allow estimation of the effects of the policies on inflation and growth, as well as on overall energy demand and CO 2 emissions. The system-wide final energy reductions is estimated to be 4.2 mtoe, or 2.6%, of total final demand for energy by 2010, including a rebound effect of 19%, with negligible effects on inflation and a slight increase in economic growth through improved international competitiveness.

Policy options for sustainable energy use in a general model of the UK economy

International Nuclear Information System (INIS)

Barker, T.; Ekins, P.; Johnstone, N.

1996-01-01

A quantitative general economic model has been developed for options available in greenhouse gas abatement policy concerning energy use. It has been applied in three exercises to explore the effects of energy taxes on the United Kingdom economy. One of these examined the effect of the proposed European Commission carbon/energy tax; the second attempts to set out a policy framework which would enable the UK to reach the IPCC target of 60% reduction in CO 2 emissions by 2040 and explores the economic implications; the third compares the proposal of the UK government to levy VAT on domestic fuel with the EC carbon/energy tax. Additionally, estimates have been made of the secondary benefits of reducing CO 2 emissions. The results present a striking contrast to much of the literature. They include the conclusions that: the EC carbon/energy tax would have negligible macroeconomic effects on the UK economy providing revenues were recycled in such a way as to neutralise inflation; reduction of UK CO 2 emissions by 60% would not necessarily cause great economic disruption; the secondary benefits of reducing CO 2 emissions are of sufficient size to alter radically the benefit cost profile of carbon abatement; equity and efficiency should be regarded as complementary, not competing, objectives in the abatement of CO 2 emissions from the domestic sector.

2015-07-01

This paper give an overview of irradiated fuel transport in the UK. It describes the design of irradiated fuel flask used by EDF Energy; operational experience and good practices learnt from over 50 years of irradiated fuel transport. The AGRs can store approximately 9 months generation of spent fuel, hence the ability to transport irradiated fuel is vital. Movements are by road to the nearest railhead, typically less than 2 miles and then by rail to Sellafield, up to 400 miles, for reprocessing or long term storage. Road and rail vehicles are covered. To date in the UK: over 30,000 Magnox flask journeys and over 15,000 AGR A2 flask journeys have been carried out.

Tang, Yongming

2016-04-01

In this talk we will describe the development and current status of the UK Earth System Model (UKESM). This project is a NERC/Met Office collaboration and has two objectives; to develop and apply a world-leading Earth System Model, and to grow a community of UK Earth System Model scientists. We are building numerical models that include all the key components of the global climate system, and contain the important process interactions between global biogeochemistry, atmospheric chemistry and the physical climate system. UKESM will be used to make key CMIP6 simulations as well as long-time (e.g. millennium) simulations, large ensemble experiments and investigating a range of future carbon emission scenarios.

Nuclear energy. Towards a re-launching in the UK?

2006-01-01

While the country recently started a debate about energy, United Kingdom is questioning about a re-launching of its nuclear energy. Even if UK's history of atomic energy is rather old (first nuclear power plant, Calder Hall, built in 1953), the lack of standardization of british plants, the fear of terrorism, the uncertainties about radioactive wastes, and a series of incidents at the Sellafield reprocessing plant have calmed down the infatuations of the past. This paper makes a brief overview of the energy prospects of a country where nuclear energy is in standby since 10 years. (J.S.)

Regional and local planning implications of energy policy: lessons from the past and issues from the future. [UK; 1967 to 1986

Energy Technology Data Exchange (ETDEWEB)

Roberts, P.W.

1986-01-01

This paper firstly examines the development of UK energy policy from 1967 to 1986; emphasis is placed upon the changing position of the coal industry, this section concludes with a consideration of the most recent energy forecasts. Following a brief examination of the relationships between energy and the regions, the paper looks in some detail at the changing patterns of coal production and employment in the UK regions. This leads to a consideration of the links between coal mining and the planning system: particular emphasis is placed upon the environmental, social and economic impacts of mining. The paper concludes with an examination of some of the key issues which may confront UK coal and the role of the coal industry in the process of regional development. 82 refs.

The UK has a binding obligation to reduce GHG emission by 80% (based on 1990 levels) by 2050. Meeting this target requires extensive decarbonisation of the UK energy system. Different pathways that achieve this target at the lowest system costs are being explored at different levels of policy and decisions on future energy infrastructure. Whilst benefits of decarbonisation are mainly focused on the impacts on climate change, there are other potential environmental and health impacts such as air-quality. In particular, a decrease in fossil fuel use by directly substituting current systems with low-carbon technologies could lead to significant reductions in the concentrations of SO2, NOX, CO and other atmospheric pollutants. So far, the proposed decarbonisation pathways tend to target the electricity sector first, followed by a transition in transport and heating technologies and use. However, the spatial dimension of where short term changes in the energy sector occur in relation to high density population areas is not taken into account when defining the energy transition strategies. This may lead to limited short-term improvements in air quality within urban areas, where use of fossil fuels for heating and transport is the main contribution to overall atmospheric pollutant levels. It is therefore imperative to explore decarbonisation strategies that prioritise transition in sectors of the energy system that produce immediate improvements in air quality in key regions of the UK. This study aims to use a combination of Remote Sensing observations and atmospheric chemistry/transport modelling approaches to estimate and map the impact on NOx of the traditional approach of decarbonising electricity first compared to a slower transition in the electricity sector, but faster change in the transport sector. This is done by generating a set of alternative energy system pathways with a higher share of zero emissions vehicles in 2030 than the energy system optimization model

Cost modelling of electricity producing hot dry rock (HDR) geothermal systems in the UK

International Nuclear Information System (INIS)

Doherty, P.S.

1992-03-01

A detailed and comprehensive cost model for Hot Dry Rock (HDR) electricity producing systems has been developed in this study. The model takes account of the major aspects of the HDR system, parameterized in terms of the main physical and cost parameters of the resource and the utilization system. A doublet configuration is assumed, and the conceptual HDR system which is defined in the study is based upon the UK Department of Energy (DEn) HDR geothermal R and D programme. The model has been used to calculate the costs of HDR electricity for a UK defined base case which represents a consensus view of what might be achieved in Cornwall in the long term. At 14.2 p/kWh (1988 costs) this cost appears to be unacceptably high. A wide-ranging sensitivity study has also been carried out on the main resource, geometrical, and operational parameters of the HDR system centred around the UK base case. The sensitivity study shows the most important parameters to be thermal gradient and depth. (Author)

Strategic energy planning within local authorities in the UK: A study of the city of Leeds

Bale, Catherine S.E.; Foxon, Timothy J.; Hannon, Matthew J.; Gale, William F.

2012-01-01

This paper considers the development of a strategic energy body in a local authority in the UK and looks at the perceived need for, and possible roles of, such a body. Historically, energy provision and management has not usually been a strategic priority for UK local authorities. Yet energy considerations are implicit in key local authority responsibilities such as transport, waste management, planning, and the provision of housing services. In addition, recent UK central government policies support the move to localism and provide incentives for low-carbon energy generation. A study was undertaken to assess the potential (including both the perceived benefits and actual capacity to deliver) for Leeds City Council to develop a strategic body to execute delivery of city-level energy decision-making. We examine the perceived benefits to a range of main stakeholders, using data drawn from interviews with managers responsible for low-carbon and renewable energy projects across the city. Through participant observation we explore the capacity of a local authority to deliver a strategic energy body, and we briefly examine the possible forms of delivery. We conclude with recommendations for national policy that would enable the development of strategic energy bodies across local governments in the UK. - Highlights: ► Strategic energy planning is currently not a priority for UK local authorities. ► We present an empirical study of strategic energy planning in local authorities. ► Results from stakeholder interviews suggest support for a strategic energy body. ► We identify the capacity barriers to implementing a strategic energy body. ► We make recommendations for ways forward and support needed from national policy.

Financial impacts of UK's energy and climate change policies on commercial and industrial businesses

2016-01-01

This study provides a detailed case study assessment of two business sites in the UK, to understand the policy drivers of increases to their energy costs and energy bills, considering all current UK energy and climate change policies. We compare our findings to more generalised, theoretical calculations of the policy cost impact on energy costs and bills – we have found no other studies as comprehensive as ours in terms of policy coverage. We find that for one site the government has over-estimated the likely energy savings due to energy efficiency options. Such differences in estimates should be taken into account when considering the efficacy of climate change policies on future energy savings. The overall impact of energy and climate change policies on costs will be of the order 0.4% of total business costs by 2020. This provides an important metric for the near-term cost of mitigation to meet longer-term climate change goals. - Highlights: •Cumulative impacts of policies on energy prices and bills were studied. •Projected bills for one site are higher than those projected by the UK government. •Results of existing theoretical studies may not be fully representative. •Impact of policies is not considered significant with respect to competitiveness.

UK Local Authority engagement with the Energy Service Company (ESCo) model: Key characteristics, benefits, limitations and considerations

Hannon, Matthew J.; Bolton, Ronan

2015-01-01

This paper explores how some UK Local Authorities (LAs) have opted to engage with the Energy Service Company (ESCo) model in a bid to enhance their influence over local energy system change and help them to deliver on their political ‘public good’ objectives. Three common approaches to LA ESCo model engagement are outlined including the: (1) LA owned ‘arm's-length’ model; (2) private sector owned concession agreement model; and (3) community owned and run model. The LA's decision to establish its own ESCo, or alternatively enter into a partnership with another, predominantly depends on: its willingness to expose itself to risk, the level of strategic control it desires and the resources it has at its disposal. However, the business case is contingent on the extent to which the national policy and regulatory framework facilitates and obligates LAs to play an active energy governance role. Stronger alignment of local and national energy agendas through communication and coordination between different governance actors could help to remove critical barriers to LA ESCo engagement and their wider energy governance activities. - Highlights: • Some UK Local Authorities (LAs) have engaged with Energy Service Company (ESCo). • Driven by a desire to shape local energy system to deliver on their objectives. • LA may establish an ‘arm's length’ ESCo or partner with a private or community ESCo. • Trade-off between strategic control over energy system change and exposure to risk. • LA can bolster ESCo business case but ultimately depends on central government

Implications of sustainability constraints on UK bioenergy development: Assessing optimistic and precautionary approaches with UK MARKAL

McDowall, Will; Anandarajah, Gabrial; Dodds, Paul E.; Tomei, Julia

2012-01-01

Bioenergy is an important renewable energy resource. However, assessments of the future of bioenergy are beset with uncertainty and contested values, suggesting that a precautionary approach to bioenergy resource development may be warranted. This paper uses UK MARKAL to examine the implications of adopting a precautionary approach to bioenergy development in the UK. The paper reports a detailed review of UK bioenergy resources and sustainability constraints, and develops precautionary and optimistic resource scenarios. The paper then examines the implications of these scenarios using the energy systems model MARKAL, finding that a precautionary approach adds to the cost of decarbonisation, but does not significantly alter the optimal technology mix. In particular, biomass and co-firing CCS emerge as optimal technologies across scenarios. The question of UK land availability for bioenergy production is highlighted within the paper. With less land available for bioenergy production, the costs of decarbonisation will rise; whereas if more land is available for bioenergy, then less land is available for either food production or ecosystem conservation. This paper quantifies one side of this trade-off, by estimating the additional costs incurred when UK land availability for bioenergy production is constrained. - Highlights: ► We assess UK bioenergy resources under optimistic and precautionary approaches. ► Using MARKAL, we find that sustainability constraints add to decarbonisation costs. ► Preferred use of bioenergy is similar in optimistic and precautionary cases. ► Best use of bioenergy is heat and power, not transport, if CCS is available. ► The marginal value of additional land availability to the energy system is high.

The role of information and communication technologies (ICTs) in household energy consumption-prospects for the UK

Growing concerns about climate change and energy security have led to a strong focus on energy demand reduction and energy efficiency within United Kingdom (UK) energy policy. At the same time, information and communication technologies (ICTs) have become pervasive in society and this has brought with it new policy options which use them as enabling technologies. One such policy option planned for implementation in the UK is the use of smart meters and real-time displays to encourage people to become more aware of their energy consumption and possibly change their energy-related behaviours. Smart meters and display units by definition link individuals, technologies and society, and their effectiveness is influenced by a range of factors. Ten semi-structured stakeholder interviews with industry, government and academia and a review of literature were conducted in order to identify which factors are most likely to contribute to the effectiveness of implementing smart meters and real-time displays in the UK. Further analysis showed a number of key themes and perspectives on behavioural change, particularly as they relate to household electricity use and the role of smart meters in the UK energy policy, including the role of ICTs in energy demand reduction more generally.

Computer modelling of the UK wind energy resource: UK wind speed data package and user manual

Energy Technology Data Exchange (ETDEWEB)

Burch, S F; Ravenscroft, F

1993-12-31

A software package has been developed for IBM-PC or true compatibles. It is designed to provide easy access to the results of a programme of work to estimate the UK wind energy resource. Mean wind speed maps and quantitative resource estimates were obtained using the NOABL mesoscale (1 km resolution) numerical model for the prediction of wind flow over complex terrain. NOABL was used in conjunction with digitised terrain data and wind data from surface meteorological stations for a ten year period (1975-1984) to provide digital UK maps of mean wind speed at 10m, 25m and 45m above ground level. Also included in the derivation of these maps was the use of the Engineering Science Data Unit (ESDU) method to model the effect on wind speed of the abrupt change in surface roughness that occurs at the coast. With the wind speed software package, the user is able to obtain a display of the modelled wind speed at 10m, 25m and 45m above ground level for any location in the UK. The required co-ordinates are simply supplied by the user, and the package displays the selected wind speed. This user manual summarises the methodology used in the generation of these UK maps and shows computer generated plots of the 25m wind speeds in 200 x 200 km regions covering the whole UK. The uncertainties inherent in the derivation of these maps are also described, and notes given on their practical usage. The present study indicated that 23% of the UK land area had speeds over 6 m/s, with many hill sites having 10m speeds over 10 m/s. It is concluded that these `first order` resource estimates represent a substantial improvement over the presently available `zero order` estimates. (18 figures, 3 tables, 6 references). (author)

Indicative energy technology assessment of UK shale gas extraction

International Nuclear Information System (INIS)

Hammond, Geoffrey P.; O’Grady, Áine

2017-01-01

Highlights: • UK shale gas ‘fracking’ is at a very early stage with an uncertain size of resource. • Shale gas extraction might benefit UK fuel security, as well as jobs and growth. • Potentially harmful environmental ‘side-effects’ must be monitored and regulated. • Gas bills for UK household and industrial consumers are unlikely to fall sharply. • Costs & benefits of shale gas fracking are unevenly distributed between communities. - Abstract: There is at present much interest in unconventional sources of natural gas, especially in shale gas which is obtained by hydraulic fracturing, or ‘fracking’. Boreholes are drilled and then lined with steel tubes so that a mixture of water and sand with small quantities of chemicals – the fracking fluid – can be pumped into them at very high pressure. The sand grains that wedge into the cracks induced in the shale rock by a ‘perforating gun’ then releases gas which returns up the tubes. In the United Kingdom (UK) exploratory drilling is at an early stage, with licences being issued to drill a limited number of test boreholes around the country. However, such activities are already meeting community resistance and controversy. Like all energy technologies it exhibits unwanted ‘side-effects’; these simply differ in their level of severity between the various options. Shale gas may make, for example, a contribution to attaining the UK’s statutory ‘greenhouse gas’ emissions targets, but only if appropriate and robust regulations are enforced. The benefits and disadvantages of shale gas fracking are therefore discussed in order to illustrate a ‘balance sheet’ approach. It is also argued that it is desirable to bring together experts from a range of disciplines in order to carry out energy technology assessments. That should draw on and interact with national and local stakeholders: ‘actors’ both large and small. Community engagement in a genuinely participative process – where the

Energy policy, the energy price fallacy and the role of nuclear energy in the UK

International Nuclear Information System (INIS)

Brookes, L.G.

1978-01-01

The widely held belief that the world energy problem will be solved by rising prices - closing the energy gap by reducing demand and bringing in new, large, previously overcostly energy sources is rejected by the author who feels that high prices are the problem and not the solution. It is argued that supply and demand will be brought into balance at some price, and the objective of energy policy should be to make it as low as possible, by concentrating on the exploitation of large, low-cost energy sources. The role of nuclear energy in this discussion is considered with respect to three specific points: the currently identified reserves of low-cost uranium, if used in fast reactors, represent an energy source greater than all other energy sources put together; nuclear power is the cheapest, safest and cleanest way of producing electricity; and electricity production accounts for a very large part of total primary energy consumption.

Assessing the environmental sustainability of energy recovery from municipal solid waste in the UK.

Jeswani, H K; Azapagic, A

Even though landfilling of waste is the least favourable option in the waste management hierarchy, the majority of municipal solid waste (MSW) in many countries is still landfilled. This represents waste of valuable resources and could lead to higher environmental impacts compared to energy recovered by incineration, even if the landfill gas is recovered. Using life cycle assessment (LCA) as a tool, this paper aims to find out which of the following two options for MSW disposal is more environmentally sustainable: incineration or recovery of biogas from landfills, each producing either electricity or co-generating heat and electricity. The systems are compared on a life cycle basis for two functional units: 'disposal of 1 tonne of MSW' and 'generation of 1 kWh of electricity'. The results indicate that, if both systems are credited for their respective recovered energy and recyclable materials, energy from incineration has much lower impacts than from landfill biogas across all impact categories, except for human toxicity. The impacts of incineration co-generating heat and electricity are negative for nine out of 11 categories as the avoided impacts for the recovered energy and materials are higher than those caused by incineration. By improving the recovery rate of biogas, some impacts of landfilling, such as global warming, depletion of fossil resources, acidification and photochemical smog, would be significantly reduced. However, most impacts of the landfill gas would still be higher than the impacts of incineration, except for global warming and human toxicity. The analysis on the basis of net electricity produced shows that the LCA impacts of electricity from incineration are several times lower in comparison to the impacts of electricity from landfill biogas. Electricity from incineration has significantly lower global warming and several other impacts than electricity from coal and oil but has higher impacts than electricity from natural gas or UK grid.

The impact of EU policies on energy use in and the evolution of the UK built environment

Energy use in buildings is influenced by a variety of factors in complex ways. Historically, in the UK the efficiency of energy use in buildings has not been a major consideration in their design. Now policy concern with climate change is changing this, because buildings have come to be perceived as the locus of energy use with the highest cost-effective energy savings potential. In the UK, the energy efficiency of the building stock is rather low. The paper focuses largely on energy use in the UK's existing building stock and the two main European Union Directives which affect it: the Energy Performance in Buildings Directive and the Energy Services Directive. The Directives are complex, and there are a number of supporting programmes set up by the European Commission to aid their implementation. Even so, they have been implemented in differing ways in different European countries, and implementation remains patchy. The Directives have the potential to be a major influence on the evolution of the UK's built environment, but their effect will depend on the details of the Directives' implementation and enforcement, many of which are not yet clear

Wind energy - current status in the UK

Lindley, D.

1995-01-01

Twenty two windfarms are operational or are under construction in the U.K. They have a total installed capacity of approximately 140 MW and will generate about 360 GWh in a full year and provide the electricity needs of about 250 000 individuals and save the emission of about 400 000 tonnes of CO 2 each year. Developments so far have required an investment of about Pound 140 million provided mostly by banks and large corporate investors. Financing these projects has broken new ground for renewable technologies and established a framework for the financing of windfarms built using future NFFO contracts. Obtaining planning consents for these windfarms has involved thirteen public inquiries, eight of which have been successful. Four of these remain unused and the result of another is awaited. Statutory and other bodies have responded to the rapid deployment of windfarms by issuing guidelines and these together with Public Inquiry documentation now provide invaluable guidance for the industry. The U.K. market is arguably the most 'open' in Europe and Danish Wind Turbine manufacturers have gained over 50 per cent of the total market. A Japanese manufacturer has gained 25 per cent whilst the major U.K. turbine supplier has gained 17 per cent market share. There are still over thirty manufacturers worldwide and signs that a combination of innovation and market pressures are continuing to reduce the costs of wind energy. (author)

The challenge to UK energy policy: An ageing population perspective on energy saving measures and consumption

International Nuclear Information System (INIS)

Hamza, Neveen; Gilroy, Rose

2011-01-01

With a focus on the residential sector, this paper explores the likelihood of the UK government meeting its energy targets. The paper contends that energy policy needs to take into account the interplay of four major factors: an ageing population of increasing diversity; a cultural inclination for older housing much of which is thermally inefficient; levels of fuel poverty; and the inexorable rise of consumer spending on leisure related services and goods. Decisions made by older households (both the poorer and the better off) may be critical to the success of energy policy. Among the better off the changing expectations of the baby boomers, with their predilection for consumption and travel, may have particular impact. The paper concludes that much of the reduction in carbon footprint made by older people's choices in heating and insulation may be offset, not only by increasing domestic thermal comfort, but also potentially by increasing consumables in the home and other consumer lifestyle choices. What could be achieved at best, may be a shift in energy mix. - Research highlights: → An aging society in the UK will not lead to reduction in energy consumption. → Physical ability, housing condition, cultural habits and energy poverty undermine policy. → Rise of home entertainment and consumerism 'Afluenza' increase energy consumption.

Can microgeneration catalyse behaviour change in the domestic energy sector in the UK?

Energy Technology Data Exchange (ETDEWEB)

Bergman, Noam (Univ. of Oxford, Environmental Change Inst., Oxford (United Kingdom))

2009-07-01

Domestic energy use accounts for more than a quarter of CO{sub 2} emissions in the UK. Traditional approaches to energy reduction look at direct emissions savings, and recommend insulation and efficiency as more cost-effective than microgeneration. However, microgeneration has indirect, 'soft' benefits and could play a significant role in emissions reduction. Current uptake of microgeneration in the UK is low, with various barriers economic, technical, cultural, behavioural and institutional both to uptake and to maximising energy and emissions savings once installed. Subsidies and spreading information alone do not guarantee maximising uptake, and even if successful, this is not enough to maximise savings. The industry focuses on maximising sales, with no incentives to ensure best installations and use; householders do not have access to the best information and user behaviour does not maximise energy and emission savings. This is related to a broader state of socio-technical 'lock-in' in domestic energy use there's a lack of connection between personal behaviour and energy consumption, let alone global climate change; energy use in the home is rising faster than energy saving measures are implemented. This suggests that a major cultural-behavioural shift is needed to reduce energy/emissions in the home. Transition theory and strategic niche management provide insights into possible systemic change, and a suitable framework for future policies, such as supporting a variety of radically innovative niches, both technological and social. Microgeneration, properly employed, has the potential to play a part in such a transition, by increasing awareness and energy literacy and empowering people to seriously engage in energy debates as producers, as well as consumers, of energy. This deeper understanding and heightened responsibility are crucial in a shift toward bottom-up emissions-reducing behaviour change and better acceptance of top

The wind energy market in the U.K. and Ireland

1996-12-31

The market for renewable energy projects has been created in England and Wales by measures established by the Electricity Act 1989 which created the Non-Fossil Fuel Obligation (NFFO). Identical market enablement mechanisms now exist for Scotland and Northern Ireland whilst yet another version of the NFFO mechanism has been established in Ireland. As a result, the UK now has 31 operational windfarms with a total rating of 195MW whilst the completion of the first windfarm in Ireland is expected in early 1997. This paper gives details of these mechanisms and the impact they have had on the creation of a renewables market. Current expectations are that additional wind energy capacity of about 900MW will be added in the UK and Ireland by the end of the millennium. This implies a market worth between US$525 million and US$600 million in turbine sales and a total turnkey investment cost of between US$1.2 billion and US$1.5 billion. 6 refs., 8 tabs.

Think globally, act locally? Local climate change and energy policies in Sweden and the UK

International Nuclear Information System (INIS)

Collier, U.; Loefstedt, R.E.

1997-01-01

While climate change is obviously a global environmental problem, there is nevertheless potential for policy initiatives at the local level. Although the competences of local authorities vary between countries, they all have some responsibilities in the crucial areas of energy and transport policy. This paper examines local competences in Sweden and the UK and looks at the responses to the climate change issue by six local authorities, focussing on energy related developments. The points of departure are very different in the two countries. Swedish local authorities are much more independent than UK ones, especially through the ownership of local energy companies. Yet, UK local authorities are relatively active in the climate change domain, at least in terms of drawing up response strategies, which they see as an opportunity for reasserting their role, after a long period of erosion of their powers. Furthermore, there is more scope for action in the UK, as in Sweden many potential measures, especially in the energy efficiency field, have already been taken. However, in both countries climate change is only a relatively marginal area of local environmental policy making and the political will, as well as the financial resources, for more radical measures are often absent.

The future of the UK gas network

Dodds, Paul E.; McDowall, Will

2013-01-01

The UK has an extensive natural gas pipeline network supplying 84% of homes. Previous studies of decarbonisation pathways using the UK MARKAL energy system model have concluded that the low-pressure gas networks should be mostly abandoned by 2050, yet most of the iron pipes near buildings are currently being replaced early for safety reasons. Our study suggests that this programme will not lock-in the use of gas in the long-term. We examine potential future uses of the gas network in the UK energy system using an improved version of UK MARKAL that introduces a number of decarbonisation options for the gas network including bio-methane, hydrogen injection to the natural gas and conversion of the network to deliver hydrogen. We conclude that hydrogen conversion is the only gas decarbonisation option that might enable the gas networks to continue supplying energy to most buildings in the long-term, from a cost-optimal perspective. There is an opportunity for the government to adopt a long-term strategy for the gas distribution networks that either curtails the iron mains replacement programme or alters it to prepare the network for hydrogen conversion; both options could substantially reduce the long-term cost of supplying heat to UK buildings. - Highlights: • We examine the long-term future of the UK gas pipe networks using the UK MARKAL model. • The iron mains replacement programme will not lead to gas infrastructure lock-in. • Bio-methane and hydrogen injection have only a small role in our future scenarios. • The most cost-optimal strategy might be to convert the networks to deliver hydrogen. • Adopting a long-term gas strategy could reduce the cost of providing heat in the UK

Integrated modelling of ecosystem services and energy systems research

2016-04-01

The UK Government is formally committed to reducing carbon emissions and protecting and improving natural capital and the environment. However, actually delivering on these objectives requires an integrated approach to addressing two parallel challenges: de-carbonising future energy system pathways; and safeguarding natural capital to ensure the continued flow of ecosystem services. Although both emphasise benefiting from natural resources, efforts to connect natural capital and energy systems research have been limited, meaning opportunities to improve management of natural resources and meet society's energy needs could be missed. The ecosystem services paradigm provides a consistent conceptual framework that applies in multiple disciplines across the natural and economic sciences, and facilitates collaboration between them. At the forefront of the field, integrated ecosystem service - economy models have guided public- and private-sector decision making at all levels. Models vary in sophistication from simple spreadsheet tools to complex software packages integrating biophysical, GIS and economic models and draw upon many fields, including ecology, hydrology, geography, systems theory, economics and the social sciences. They also differ in their ability to value changes in natural capital and ecosystem services at various spatial and temporal scales. Despite these differences, current models share a common feature: their treatment of energy systems is superficial at best. In contrast, energy systems research has no widely adopted, unifying conceptual framework that organises thinking about key system components and interactions. Instead, the literature is organised around modelling approaches, including life cycle analyses, econometric investigations, linear programming and computable general equilibrium models. However, some consistencies do emerge. First, often contain a linear set of steps, from exploration to resource supply, fuel processing, conversion

Energy and capital: substitutes or complements. Some results for the UK industrial sector

This paper investigates the substitutability or complementarity possibilities between capital, labor, and energy in the UK industrial sector, with particular attention to the capital-energy relationship. It is found, using the translog-cost-function approach, that capital and labor as well as energy and labor are substitutes. However, capital and energy are found to be complements. 11 references, 3 tables.

The future value of electrical energy storage in the UK with generator intermittency

Energy Technology Data Exchange (ETDEWEB)

2004-07-01

The intermittent nature of renewable energy sources increases the need for storage of electric power - the need is greatest in the case of wind power. This study looked at the potential value of power storage as a means of coping with variable power demand which, in the case of wind power, is itself intermittent. The benefits of using storage for part of the reserve needs compared with the reserve in the form of part-loaded conventional forms of generation was a feature of the study. The benefits were assessed in terms of (a) savings in fuel costs associated with balancing the systems; (b) carbon dioxide emissions, and (c) the additional amount of wind energy that can be absorbed. The work was conducted as part of the a UK DTI programme on New and Renewable Energy Sources.

Evaluating the applicability of integrated domestic energy consumption frameworks in the UK

International Nuclear Information System (INIS)

Keirstead, James

2006-01-01

Domestic energy consumption (DEC) has been traditionally understood using disciplinary perspectives, focusing on specific components of the energy consumption system such as technologies or costs. However, early attempts to encourage energy conservation demonstrated that these frameworks often miss important contextual factors such as cultural values and behavioural interactions with technologies. This evidence, combined with the present need for energy policies that can address environmental, social, and economic concerns, suggests that a broader perspective is needed. Integrated frameworks of DEC were first proposed over 20 years ago but very little has been said about the ideas proposed in these papers, whether it be critiquing their form or assessing their impact on theory and practice. This paper attempts to fill this gap by examining the influence of integrated frameworks in academic literature and in UK energy policy. It is argued that a common language could stimulate renewed interest in the integrated perspective and thereby help policy makers meet these diverse goals. To this end, a flexible agent-based framework is proposed to stimulate debate and clarify the role of an integrated approach to domestic energy policy

Described herein are the results of the FY1994 research program for operational studies on a large-scale wind energy conversion system. A total of 8 domestic and foreign cases are studied for wind energy conversion cost, to clarify the causes for higher cost of the Japanese system. The wind power systems studied include Japanese (5 units at Tappi Wind Park, the same type supplied by company M), US (California Wind Farm, 300 units) and UK (Wales Wind Farm, 103 units) systems. The investment costs are 639, 285 and 189 thousand yen/kW for the Japanese, US and UK systems, respectively. It is also revealed that the power plant itself and assembling costs account for a majority (70 to 88%) of the total investment cost. The higher cost of the Japanese system results from a smaller number of units installed, and the power plant cost can be drastically reduced by mass production. Increasing size also reduces cost greatly.

The UK-DALE dataset, domestic appliance-level electricity demand and whole-house demand from five UK homes.

Many countries are rolling out smart electricity meters. These measure a home's total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the 'ground truth' demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

Learning from the experiences of others: the development of energy regulation in UK and Greece

International Nuclear Information System (INIS)

Metcalf, R.; Rose, N.

2002-01-01

In this paper I have described how regulation of the energy sector has developed in two member states of the European Union. I have taken as my examples the UK and Greece. As the first country in the EU to advance to full market liberalisation the UK has already been through many phases of development in the energy sector and the process of regulation has had to adapt to deal with changing circumstances. Greece finds itself at a much earlier stage of development and regulation is a much newer factor in its energy market. It is hoped that by choosing two countries at different stages of developing their energy markets valuable examples can be found for challenges which are now being met in Croatia.(author)

Implications of shale gas exploitation for UK climate change targets under a production-based accounting system.

Turk, J.; Reay, D.; Haszeldine, S.

2017-12-01

The shale gas boom in the USA has seemingly decreased the greenhouse gas intensity of electricity generation in the USA over the last decade. The United Kingdom is supporting its own shale gas industry to increase its own domestic energy supply. The UK's climate change policy is underpinned by defined national carbon budgets periods. The UK has met Carbon Budget 1 (2008 - 2012) and is likely to meet the second and third carbon budgets (2013 - 2022). There is a projected shortcoming in the fourth carbon budget (2023 - 2027). This shortfall may be increased as the UK pursues a domestic shale gas industry. Under the current production-based GHG accounting system, the UK is incentivized to import natural gas rather than produce it domestically. If the projected gas supply were to be met by UK shale gas, we project additional greenhouse gas emissions which would need to be accommodated during Carbon Budget periods 3 - 6. Additionally, natural gas electricity generation will contribute to sustaining grid electricity emissions during the same time period within the traded European Union emissions cap.

Heffron, Raphael J.; Johnston, Angus; McCauley, Darren; Jenkins, Kirsten

2013-01-01

The ambition of this conference was to deliver a first examination of how policy is delivered in the context of low-carbon energy infrastructure in the UK. The UK has been developing policy in this area since 2002 (Heffron, 2013). Finally, as the decade passed, in November 2012 an Energy Bill was put before the UK Parliament. One of the chief purposes of this Energy Bill is to establish the right environment for new electricity generation infrastructure in the low-carbon sector. There is significant debate on how this will be achieved and, indeed, whether this piece of legislation will actually deliver this outcome. This conference aimed to examine the dynamics of policy delivery. Throughout the day, there was entertaining discussion as a variety of conference presenters provided interesting contributions on how to deliver such policy goals. In total, there were twelve speakers throughout the day representing the UK (University of Oxford, Pinsent Masons Law Firm, University of Stirling, University of Dundee and University of Aberdeen), and also those who provided lessons from abroad from the University of Copenhagen, Central European University, Milieu Ltd., Pillsbury Law Firm (Washington DC, US) and the Conservation Law Foundation (MA, US)

Re-materialising energy use through transparent monitoring systems

Burgess, Jacquelin; Nye, Michael

2008-01-01

This paper reviews the effect of transparent energy monitoring systems on the purchasing, production and energy use behaviour of consumers and producers. Relevant literature is explored on the linkages between feedback, risk and responsibility, knowledge, economic drivers, and sustainable energy consumption. Drawing on international as well as UK-specific experiences, the paper focuses on the prospects for current and future energy monitoring systems to 're-materialise' energy use in economic and environmental terms that are more meaningful, and thus more behaviourally significant, to a substantially wider range of energy users than today's. Appliance labelling, smart metering and carbon footprint analyses are explored as case studies

Governance and legitimacy aspects of the UK biofuel carbon and sustainability reporting system

2011-01-01

Biofuel policy has become highly contentious in Europe. In this paper we discuss the governance and legitimacy aspects of the carbon and sustainability system of the UK Renewable Transport Fuel Obligation (RTFO), both before and after implementation of the Renewable Energy Directive. RTFO certification is of a meta-type, being built upon existing certification and labelling schemes, each of which are more or less contested by NGOs. Despite the RTFO being based on these non-state initiatives, so far the concerns of environment and development NGOs and others have not been given serious expression in regulatory terms. Indeed, biofuel policy development in the UK has arguably been unduly non-responsive to critical opinion, given the limited scientific base on biofuel impacts and the reliance of RTFO sustainability certification on non-state actors and schemes. Drawing on documentary evidence, interviews and three sets of literatures - co-production of regulation; post-normal science; and legitimacy of non-state certification and labelling processes - we suggest that until concerned voices are given a stronger expression in UK and EC biofuel policy development, the policy cannot yet be said to have achieved a wide social mandate. - Research highlights: → Interviews with largely non-commercial actors show a high level of concern about EC/UK biofuel policy. → The scientific uncertainties and complexity of biofuels justify inclusive policy development. → Statutory UK and EC biofuel certification will rely heavily on non-state actors and processes.→ EC/UK biofuel certification can learn from legitimisation processes more usually relevant to non-state initiatives.

The threat of global warming, environmental instability and the possible use of green or carbon taxes on fossil fuels has increased the need for energy efficiency. Energy Conservation is now recognised as one of the easiest and most cost-effective ways of limiting or reducing CO[sub 2] emissions. Large UK companies are now assessing how much CO[sub 2] they dissipate to the environment and reviewing strategies to reduce this either in response to consumer demand or as a corporate policy decision. Computer-based information systems already exist to monitor and report on fluctuations in energy consumption. These are called Monitoring and Targeting (M and T) systems. This paper explains what M and T systems are and how they are being extended to cover reporting on corporate fuel-based CO[sub 2] emissions to help provide an integrated energy and environmental-management information system.

Highlights: • The economic and environmental benefits of smart EVs/HPs are quantified. • This paper implements an advanced stochastic analytical framework. • Operating patterns and potential flexibility of EVs/HPs are sourced from UK trials. • A comprehensive set of case studies across UK future scenarios are carried out. - Abstract: This paper presents an advanced stochastic analytical framework to quantify the benefits of smart electric vehicles (EVs) and heat pumps (HPs) on the carbon emission and the integration cost of renewable energy sources (RES) in the future UK electricity system. The typical operating patterns of EVs/HPs as well as the potential flexibility to perform demand shifting and frequency response are sourced from recent UK trials. A comprehensive range of case studies across several future UK scenarios suggest that smart EVs/HPs could deliver measurable carbon reductions by enabling a more efficient operation of the electricity system, while at the same time making the integration of electrified transport and heating demand significantly less carbon intensive. The second set of case studies establish that smart EVs/HPs have significant potential to support cost-efficient RES integration by reducing: (a) RES balancing cost, (b) cost of required back-up generation capacity, and (c) cost of additional low-carbon capacity required to offset lower fuel efficiency and curtailed RES output while achieving the same emission target. Frequency response provision from EVs/HPs could significantly enhance both the carbon benefit and the RES integration benefit of smart EVs/HPs.

A scoping study: demand side measures on the UK electrical system

NONE

2005-07-01

The study is intended to eventually bring about a number of improvements in the UK electrical system, particularly in regard to Demand Side Management (DSM). Among the benefits envisaged are (a) increased security of supply when the network is under stress; (b) reduction in costs; (c) simpler outage management; (d) carbon saving and (e) increased energy efficiency. So far, these potential benefits have attracted little attention in the residential and small business sectors of the market: suggested reasons for this are listed. Taking into account the experience of other countries, three options are presented for a UK DSM programme: they are (i) customer initiated; (ii) supplier initiated and (iii) distributor initiated. At present, all the suggested options need further study and to aid the development for small customers, five possible initiatives are suggested. This final report (95 pages) includes a detailed description of the research required and a tender process for a customer-initiated programme. The report was prepared by KEMA Limited under contract to the DTI.

Financing the UK's renewable energy boom

International Nuclear Information System (INIS)

Lindley, D.

1996-01-01

The opportunity to invest in and operate renewable energy power projects in the United Kingdom is the result of the financial measures established by the Electricity Act 1989, which created the Non-Fossil Fuel Obligation. In the three different orders specified so far, approximately 1400 MW (declared net capacity) of contracts have been awarded to schemes generating electricity from wind, hydro, landfill gas, sewage gas, waste combustion and other combustion (using forestry wastes and biomass) schemes. The majority of projects that have become operational so far have been financed either on 'balance sheet' or by a combination of non-recourse or limited recourse project loans and investor equity. In order to fulfil the government's goal to have 1500 MW (declared net capacity) of electricity from renewables by 2000 and a total investment of in excess of 1.5 billion pounds will be required. This paper reviews the terms of the Non Fossil Fuel Obligation, gives details of contracts awarded so far, reviews the financing methods used, summarises the project risk and the means of mitigation and provides case histories of several different renewable energy projects financed in the UK.

Negative rebound and disinvestment effects in response to an improvement in energy efficiency in the UK economy

International Nuclear Information System (INIS)

Turner, Karen

2009-01-01

This paper uses a computable general equilibrium (CGE) framework to investigate the conditions under which rebound effects may occur in response to increases in energy efficiency in the UK national economy. Previous work for the UK has suggested that rebound effects will occur even where key elasticities of substitution in production are set close to zero. The research reported in this paper involves carrying out a systematic sensitivity analysis, where relative price sensitivity is gradually introduced into the system, focusing specifically on elasticities of substitution in production and trade parameters, in order to determine conditions under which rebound effects become a likely outcome. The main result is that, while there is positive pressure for rebound effects even where (direct and indirect) demands for energy are very price inelastic, this may be partially or wholly offset by negative income, competitiveness and disinvestment effects, which also occur in response to falling energy prices. The occurrence of disinvestment effects is of particular interest. These occur where falling energy prices reduce profitability in domestic energy supply sectors, leading to a contraction in capital stock in these sectors, which may in turn lead to rebound effects that are smaller in the long run than in the short run, a result that runs contrary to the predictions of previous theoretical work in this area.

Computer modelling of the UK wind energy resource: final overview report

Energy Technology Data Exchange (ETDEWEB)

Burch, S F; Ravenscroft, F

1993-12-31

This report describes the results of a programme of work to estimate the UK wind energy resource. Mean wind speed maps and quantitative resource estimates were obtained using the NOABL mesoscale (1 km resolution) numerical model for the prediction of wind flow over complex terrain. NOABL was used in conjunction with digitised terrain data and wind data from surface meteorological stations for a ten year period (1975-1984) to provide digital UK maps of mean wind speed at 10m, 25m and 45m above ground level. Also included in the derivation of these maps was the use of the Engineering Science Data Unit (ESDU) method to model the effect on wind speed of the abrupt change in surface roughness that occurs at the coast. Existing isovent maps, based on standard meteorological data which take no account of terrain effects, indicate that 10m annual mean wind speeds vary between about 4.5 and 7 m/s over the UK with only a few coastal areas over 6 m/s. The present study indicated that 23% of the UK land area had speeds over 6 m/s, with many hill sites having 10m speeds over 10 m/s. It is concluded that these `first order` resource estimates represent a substantial improvement over the presently available `zero order` estimates. (20 figures, 7 tables, 10 references). (author)

A golden age or a false dawn? Energy efficiency in UK competitive energy markets

International Nuclear Information System (INIS)

Eyre, N.

1998-01-01

Liberalisation of energy markets may affect the prospects for energy efficiency in a variety of ways. Downward pressure on prices will reduce incentives for efficiency and the end of a supply monopoly makes more difficult mandating demand side management programmes. On the other hand, the removal of price controls could end some regulatory disincentives, and liberalisation enables suppliers to market energy efficiency bundled with energy units. The overall effects of liberalisation for energy efficiency are therefore complex. This paper focuses on the effects of liberalisation on those characteristics of energy markets which underpin long-term energy inefficiency. These barriers to energy efficiency have been shown to arise from fundamental features of traditional utility markets - notably centralisation, commoditization and the complexity of demand side investment. The extent to which these will be altered in liberalised markets in the UK is considered. It is concluded that some important market imperfections are not addressed by competition in the supply of energy commodities. However, more fundamental changes may in the longer term encourage more differentiation in supply markets, in which there could be higher priority for energy efficiency. The policy measures which might encourage the process are discussed. (author)

Highlights: • Optimisation of energy storage system with wind power plant for frequency response. • Energy storage option considered could be economically viable. • For a 50 MW wind farm, an energy storage system of 5.3 MW and 3 MW h was found. - Abstract: This paper proposes a methodology for the economic optimisation of the sizing of Energy Storage Systems (ESSs) whilst enhancing the participation of Wind Power Plants (WPP) in network primary frequency control support. The methodology was designed flexibly, so it can be applied to different energy markets and to include different ESS technologies. The methodology includes the formulation and solving of a Linear Programming (LP) problem. The methodology was applied to the particular case of a 50 MW WPP, equipped with a Vanadium Redox Flow battery (VRB) in the UK energy market. Analysis is performed considering real data on the UK regular energy market and the UK frequency response market. Data for wind power generation and energy storage costs are estimated from literature. Results suggest that, under certain assumptions, ESSs can be profitable for the operator of a WPP that is providing frequency response. The ESS provides power reserves such that the WPP can generate close to the maximum energy available. The solution of the optimisation problem establishes that an ESS with a power rating of 5.3 MW and energy capacity of about 3 MW h would be enough to provide such service whilst maximising the incomes for the WPP operator considering the regular and frequency regulation UK markets

The Radiotherapy Dosimetry Audit System In the UK

Thwaites, D.I.

1999-01-01

Two national radiotherapy dosimetry intercomparisons have been earned out in the UK, involving all radiotherapy institutes. The first was concerned with megavoltage photon beams and looked at beam calibration and simple three-field planned distributions in a geometric phantom. The intercomparisons were carried out by an independent intercomparison physicist visiting each department in turn and making measurements with ion chambers, following a fixed protocol. The beam calibration intercomparison was earned out on every 60 C o beam and every MV x-ray beam, whilst the planned comparisons were carried out on one beam only. The plans included effects of wedges, oblique incidence and inhomogeneities. The study was unfunded and took a significant time (1988-1991) to cover the 65 or so centres. It was followed up by a national electron dosimetry intercomparison which was fended (Department of Health) and which ran from 1994-1996. This audited three electron beam energies in each centre (depth dose, beam energy, dose calibration) and also included a follow-up of the original photon beam intercomparison. In general these studies showed good consistency of dosimetry across the UK centres, with mean (measured/locally stated) doses being close to unity and standard deviations of the distributions of values being approx. 1.5 and 1% for photons, 1.8% for electrons for beam calibration and 2.5-3.5% for the planned multi-beam situations. 97-100% of measurements were within the pre-set 3% tolerance for beam calibration and around 90% of the measurements within a pre-set 5% tolerance for planned situations. The studies did highlight some areas where increased on Q A could provide benefits. In particular the photon intercomparison discovered one 60 C o unit mis calibration which led to national recommendations for the implementation of Quality Systems in radiotherapy departments

Tidal energy UK Government R and D programme. Final report

Craig, J.W.; Davies, L.M.; Allington, M.A.

1996-05-01

The United Kingdom Government's research programme into the feasibility of exploiting tidal power for electricity generation in Britain's estuaries is described in this document. The history of the research is included from the Severn Barrage Committee in 1978 to the conclusion of the tidal energy barrages programme in 1994. The programme sought to reduce uncertainty on costs, technical performance and environmental and regional effects, in order to firm up on decisions on whether to construct certain specific barrages. It was concluded that, while technically feasible, tidal power from barrages, was and will continue to be uneconomic compared with other energy sources. Other renewable technologies would receive further research. (UK)

Distributional implications of higher energy prices in the UK

Energy Technology Data Exchange (ETDEWEB)

Common, M

1985-06-01

Results presented are consistent with the claim that higher energy prices are regressive in impact in the UK. However, the size of the impact on the worst affected is not found to be as great as might be expected. It is not at all obvious that the size of impact established is such as to justify the use of terms such as fuel poverty or arguments for the subsidization of fuels purchased by those on low incomes. This is not to say that low income households in the UK have not in the last decade had serious problems with fuel bills. The evidence of, for example, the Supplementary Benefits Commission (1979) makes it obvious that large numbers of households have experienced real problems. However, from the evidence considered here, it is reasonable to suggest that the origin of such problems lies more with the technical characteristics of the consumption act, and with institutional arrangements for payment, in respect of heating and lighting, than with impact of higher fuel prices as such. Gas and electricity consumption is not readily monitored as use occurs, and payment is often by billing well after consumption. Casual observation suggests that the difficulties with fuel bills as reported to welfare agencies are predominantly difficulties with gas and electricity bills. The results also show that of the total impact of higher energy prices on cost of living indices, only 50% arises via the consumption of fuels in the home.

EDF Energy/Nuclear Generation is the owner and operator of 14 Advanced Gas cooled Reactors (AGR) and one Pressurised Water Reactor (PWR), on 8 nuclear stations in the UK. EDF Energy/Nuclear Generation is responsible for all the activities associated with the end of life of its nuclear installations: de-fuelling, decommissioning and waste management. As the first AGR is forecast to cease generation within 10 years, EDF Energy has started planning for the decommissioning. This paper covers: - broad outline of the technical strategy and arrangements for future de-fuelling and decommissioning works on the UK AGR fleet, - high level strategic drivers and alignment with wider UK nuclear policy, - overall programme of preparation and initial works, - technical approaches to be adopted during decommissioning.

Achieving energy efficiency through product policy: the UK experience

International Nuclear Information System (INIS)

Boardman, Brenda

2004-01-01

The focus of this paper is on energy efficiency of domestic equipment. It is contended that, in the UK and--by extension--elsewhere. Government has to take the lead in defining low-energy standards for products. In the absence of policy, manufacturers do not recognize the need for carbon reductions in the equipment they design and consumers are unaware of the variation in energy performance in the product range. At present, neither market pull nor technology push can be relied upon to deliver energy savings. The imposition of a weak minimum standard on domestic fridges and freezers in 1999 will, over the lifetime of the appliances already sold by December 2002, save 1 Mt C of carbon dioxide at nil cost to government or to the manufacturers, and a net benefit to consumers of pound 855 m: a highly cost-effective policy. The difference between energy efficiency and energy conservation is that it takes time for the cumulative benefits of an energy efficiency improvement to result in the maximum effect on energy demand reduction: the benefits of the 1999 energy efficiency standard will accumulate until at least 2020. This period is equivalent to the cycle of stock replacement for that particular object. The final level of energy conservation depends upon the offsetting effects of growth in ownership levels and the size of new equipment purchases

2012-01-01

There is increasing focus on the role small-scale decentralised renewable energy developments could play in helping the UK meet its target of over 15% renewable energy by the year 2020 and alter energy behaviours through active community engagement. Upland areas are considered key areas where such community-based developments could occur due to their natural resources and range of community scales. This study uses GIS-based techniques to develop a methodology that assesses the regional-scale potential for community-based renewable electricity across Cumbria and whether a combination of these developments at the community-scale could make a significant contribution to local electricity consumption. This methodology looks at a range of technologies including hydro-power, wind-power, solar PV and bioenergy. The results suggest there is ample resource available for small communities by combining a mix of localised renewable electricity developments, which is highlighted through energy scenarios for a selected community. Further work will investigate whether this potential can be realised in reality by looking at resource resilience and community-level acceptability. - Highlights: ► A mix of wind, solar, bioenergy and hydro-power options are presented for Cumbria, UK. ► High resolution spatial analysis is conducted focussing on localised developments. ► Locations with sufficient renewable electricity potential were identified. ► Renewable options are explored further through a town case study. ► Scenarios consider different scales, mixes and contributions to local energy demand.

Household energy consumption in the UK: A highly geographically and socio-economically disaggregated model

International Nuclear Information System (INIS)

Druckman, A.; Jackson, T.

2008-01-01

Devising policies for a low carbon society requires a careful understanding of energy consumption in different types of households. In this paper, we explore patterns of UK household energy use and associated carbon emissions at national level and also at high levels of socio-economic and geographical disaggregation. In particular, we examine specific neighbourhoods with contrasting levels of deprivation, and typical 'types' (segments) of UK households based on socio-economic characteristics. Results support the hypothesis that different segments have widely differing patterns of consumption. We show that household energy use and associated carbon emissions are both strongly, but not solely, related to income levels. Other factors, such as the type of dwelling, tenure, household composition and rural/urban location are also extremely important. The methodology described in this paper can be used in various ways to inform policy-making. For example, results can help in targeting energy efficiency measures; trends from time series results will form a useful basis for scenario building; and the methodology may be used to model expected outcomes of possible policy options, such as personal carbon trading or a progressive tax regime on household energy consumption

Micro-hydro power in the UK: The role of communities in an emerging energy resource

Research around micro-hydro power is focused on technical aspects with limited understanding of the social organisation and environmental implications. We examine the ways in which micro-hydro is engaged by people and organisations as a means of contributing to the UK's policy ambition for renewable energy. We bring to the fore the way in which expertise is used and contested. A web based review of micro-hydro schemes in the UK was undertaken and a detailed evaluation of two schemes in the North of England was conducted to determine how expertise and contestation figures in community schemes. Results demonstrate a rapid expansion of micro-hydro in the UK. Ownership/control is highly ‘community based’. Until now research around micro-hydro has been dominated by technical approaches with schemes defined in terms of hardware. We propose a third dimension to Walker and Cass's (2007) classification of renewable energy developments: the environmental dimension. We suggest this dimension of micro-hydro is critical, both in terms of the extent to which resources can be realised but also the ways in which it might attract controversy, in particular around how expertise is used and valued. - Highlights: • Analysis of micro-hydro schemes in the UK demonstrates a recent rapid expansion. • We propose a third dimension to renewable energy developments: the environmental dimension. • The environmental dimension of micro-hydro determines how resources are realised. • Environmental features underpin the controversy which can emerge around schemes. • The ownership of micro-hydro schemes is highly ‘community based’

Uncertainties in key low carbon power generation technologies - Implication for UK decarbonisation targets

International Nuclear Information System (INIS)

Kannan, R.

2009-01-01

The UK government's economy-wide 60% carbon dioxide reduction target by 2050 requires a paradigm shift in the whole energy system. Numerous analytical studies have concluded that the power sector is a critical contributor to a low carbon energy system, and electricity generation has dominated the policy discussion on UK decarbonisation scenarios. However, range of technical, social and market challenges, combined with alternate market investment strategies mean that large scale deployment of key classes of low carbon electricity technologies is fraught with uncertainty. The UK MARKAL energy systems model has been used to investigate these long-term uncertainties in key electricity generation options. A range of power sector specific parametric sensitivities have been performed under a 'what-if' framework to provide a systematic exploration of least-cost energy system configurations under a broad, integrated set of input assumptions. In this paper results of six sensitivities, via restricted investments in key low carbon technologies to reflect their technical and political uncertainties, and an alternate investment strategies from perceived risk and other barriers, have been presented.

Renewable energy will potentially make an important contribution towards the dual aims of meeting carbon emission reduction targets and future energy demand. However, some technologies have considerable potential to impact on the biodiversity of the environments in which they are placed. In this study, an assessment was undertaken of the realistic deployment potential of a range of renewable energy technologies in the UK, considering constraints imposed by biodiversity conservation priorities. We focused on those energy sources that have the potential to make important energy contributions but which might conflict with biodiversity conservation objectives. These included field-scale solar, bioenergy crops, wind energy (both onshore and offshore), wave and tidal stream energy. The spatially-explicit analysis considered the potential opportunity available for each technology, at various levels of ecological risk. The resultant maps highlight the energy resource available, physical and policy constraints to deployment, and ecological sensitivity (based on the distribution of protected areas and sensitive species). If the technologies are restricted to areas which currently appear not to have significant ecological constraints, the total potential energy output from these energy sources was estimated to be in the region of 5,547 TWh/yr. This would be sufficient to meet projected energy demand in the UK, and help to achieve carbon reduction targets. However, we highlight two important caveats. First, further ecological monitoring and surveillance is required to improve understanding of wildlife distributions and therefore potential impacts of utilising these energy sources. This is likely to reduce the total energy available, especially at sea. Second, some of the technologies under investigation are currently not deployed commercially. Consequently this potential energy will only be available if continued effort is put into developing these energy sources

The purpose of this paper is twofold: to determine if the integration of energy efficient technologies in UK supermarkets can determine consumer behaviour, and to establish if such activities can help satisfying the environmental elements of the clients corporate social responsibilities (CSR) in an attempt to create a competitive advantage. A literature review of existing material considered the history and drivers of sustainability, the types of energy efficient technologies and factors concerning CSR and consumer behaviour in relation to the supermarket industry. Interviews with 15 senior store managers were recorded and transcribed. The opinions of the senior store managers were then sought and analysed using qualitative research software NVivo software. Validity of the data was achieved at a later stage through workshops. The results of this paper suggested that there is a definite lack of awareness and knowledge amongst customers regarding energy efficient technologies. From the findings, it was further established that the key driver for retailers who integrate energy efficient technologies is fiscal incentives, although it was suggested some retailers use CSR strategies to report there are environmental achievements it was ultimately found that cost savings were the primary driver. - Highlights: • The effect of sustainability towards consumer behaviour was explored. • Majority of consumers are unaware of energy efficient technologies. • Energy efficient technologies do not determine or create shifts in paradigm in consumer actions. • Stores are driven to integrate energy efficient technologies more by government legislation. • Participants were clear in making the point that their image and reputation was based on trust

On the Defence: UK cultural narratives of mistrust between energy users and providers

Directory of Open Access Journals (Sweden)

Cathy Bailey

2018-03-01

Full Text Available In general, households rely on energy providers to supply essential energy services such as gas and electricity. It seems reasonable to assume that it is mutually beneficial to have a customer and supplier relationship invested in trust. Key findings from the qualitative evaluation findings of a UK Comic Relief-funded energy services and managing money better programme, suggest that the programme’s effectiveness was strongly affected by negative narratives about energy suppliers. Such narratives, rooted in feelings of being labelled a ‘cheat’ or incapable of sorting their own affairs on one side and views of energy providers being exploitative and profit-hungry on the other, engendered a common, oppositional ‘united against them’ culture, built on reciprocal mistrust and disrespect. This analysis is not unique to our research, as nationally, at least and within the last decade, there has been a decline in public trust of energy providers, with a suggestion that profit has come before people. The 3-year evaluation carried out by Northumbria University, UK with the research led by a North East England registered credit union and social landlord, assessed the quality of life impacts of a face-to-face energy advice service. Expert Energy Advisors offered free home visits and gave people aged 50 and over the tools to reduce and manage energy usage, question energy companies about tariff terms and conditions and ensure maximum take up of benefit entitlements. Whilst findings point to positive health and social benefits, including reducing high anxiety about unmanageable bills, being able to question and challenge energy providers ‘high’ bills and tariffs and passing on such skills to others, there remained a ‘taken-for-granted’ mistrust of energy providers. We argue that for public good to come from public health research, we need to understand and appropriately address the roots of such cultural narratives.

There is clear consensus on the value of diversity as applied to energy systems, with the concept being a central reference for governments, industry and civil society organizations. Given its importance in policy debates, we have sought to explore the specification and measurement of diversity. We show that although conceptualisation of diversity has developed over recent years, along with increasingly elegant mathematical representations, the concept is, at core, subjective and irreducibly context specific. Subjectivity derives from determination of boundaries and the placement of objects into categories, the acts that make assessment of diversity possible. We illustrate this point with an empirical analysis of the diversity of renewable energy generation in the UK over the past century. By applying a range of different indices and classifications to this dataset, we demonstrate that the ‘diversity story’ told is different in each case. As such we argue that the analysis of diversity must be produced and consumed critically. Attempts to expand, manage, measure or comment upon the diversity of a system, be it an ecosystem, an organization, an economy, or an energy portfolio, demand rigor, reflexivity and, most importantly, transparency. - Highlights: • We review concepts of diversity and approaches to diversity measurement. • We examine the inherent subjectivity associated with any such measurement. • We illustrate this by applying different diversity indices to the same dataset. • The dataset used is the UK renewable energy portfolio over the past 100 years. • Different measures yield different results telling different ‘diversity stories’

Renewable electricity generation: supporting documentation for the Renewables Advisory Board submission to the 2006 UK energy review

International Nuclear Information System (INIS)

2006-01-01

The Renewables Advisory Board (RAB) is an independent, non-departmental public body, sponsored by the DTI, which brings together representatives of the renewable sector and the unions. Electricity generation from renewable energy sources offers a range of advantages to the UK electricity-generating sector. This document, prepared as supporting documentation for the RAB submission to the 2006 Energy Review, examines the role of renewable energy in improving security of supply, lowering financial risk for energy portfolios, and reducing electricity cost volatility and fuel costs for the UK. Key topics addressed in this report include: resource security; security of supply; price security; and operational security. Also covered are variability patterns, financial costs and benefits of renewable generation. Maintaining the option and flexibility of future renewables development has a real option value, with overseas evidence showing that this can be significant

Energy efficient cooking systems, food-preparation facilities, and human diets

1987-07-01

The opportunities for saving energy, which are available to those working within the final link of the UK food system, i.e. at, or in relation to, the points of consumption are identified. Substantial prospective savings exist, because relatively little attention has, as yet, been given to energy-thrift in food-preparation facilities. Within the food-service industry, cooking systems are characterised by high thermal capacities, excessive external surface temperatures and poorly-designed control systems. Catering staff, who use such appliances, are rarely trained to use energy wisely when preparing foods, and kitchens tend to be designed without sufficient regard to energy-thrift. Similar problems prevail in domestic kitchens. However, manufacturers still provide household appliances, which are unnecessarily energy-profligate. (author).

Fiscal impacts of energy efficiency programmes—The example of solid wall insulation investment in the UK

International Nuclear Information System (INIS)

Rosenow, Jan; Platt, Reg; Demurtas, Andrea

2014-01-01

Programmes supporting the installation of energy efficiency measures typically incur a cost in the form of subsidies as well as lost VAT income due to reduced energy consumption. Those costs are to some extent offset by the tax receipts and other revenue streams generated as a result of the activities promoted under the programme. In this paper we analyse the budgetary effects of energy efficiency programmes focusing on the example of solid wall insulation in the UK. Three distinct subsidy options have been defined and modelled for the purpose of this research including two policies with varying degrees of direct subsidy and a low interest loan scheme. Our analysis shows that a significant amount of the cost of a scheme funding solid wall insulation would be offset by increased revenues and savings. A loan scheme, due to the high leverage, achieves not only budget neutrality but generates additional revenue for the Exchequer. - Highlights: • First assessment of fiscal effects of subsidising energy efficiency technologies in the UK. • Contribution to debate around wider benefits of funding energy efficiency. • Original economic modelling

Energy and greenhouse gas balance of the use of forest residues for bioenergy production in the UK

2011-01-01

Life cycle analysis is used to assess the energy requirements and greenhouse gas (GHG) emissions associated with extracting UK forest harvesting residues for use as a biomass resource. Three forest harvesting residues were examined (whole tree thinnings, roundwood and brash bales), and each have their own energy and emission profile. The whole forest rotation was examined, including original site establishment, forest road construction, biomass harvesting during thinning and final clear-fell events, chipping and transportation. Generally, higher yielding sites give lower GHG emissions per ‘oven dried tonne’ (ODT) forest residues, but GHG emissions ‘per hectare’ are higher as more biomass is extracted. Greater quantities of biomass, however, ultimately mean greater displacement of conventional fuels and therefore greater potential for GHG emission mitigation. Although forest road construction and site establishment are “one off” events they are highly energy-intensive operations associated with high diesel fuel consumption, when placed in context with the full forest rotation, however, their relative contributions to the overall energy requirements and GHG emissions are small. The lower bulk density of wood chips means that transportation energy requirements and GHG emissions are higher compared with roundwood logs and brash bales, suggesting that chipping should occur near the end-user of application. -- Highlights: ► GHGs and fuel consumption assessed for UK clear-fell conifer forest residues. ► Energy use and GHG emissions for forest road construction characterised. ► Lower energy requirements and GHG emissions per ODT for higher yielding sites. ► Transport energy and GHG emissions higher for wood chip than roundwood or brash bales. ► Results useful in predicting GHG mitigation potential from UK commercial conifer forest residues.

Modelling Socio-Environmental Sensitivities: How Public Responses to Low Carbon Energy Technologies Could Shape the UK Energy System

Full Text Available Low carbon energy technologies are not deployed in a social vacuum; there are a variety of complex ways in which people understand and engage with these technologies and the changing energy system overall. However, the role of the public’s socio-environmental sensitivities to low carbon energy technologies and their responses to energy deployments does not receive much serious attention in planning decarbonisation pathways to 2050. Resistance to certain resources and technologies based on particular socio-environmental sensitivities would alter the portfolio of options available which could shape how the energy system achieves decarbonisation (the decarbonisation pathway as well as affecting the cost and achievability of decarbonisation. Thus, this paper presents a series of three modelled scenarios which illustrate the way that a variety of socio-environmental sensitivities could impact the development of the energy system and the decarbonisation pathway. The scenarios represent risk aversion (DREAD which avoids deployment of potentially unsafe large-scale technology, local protectionism (NIMBY that constrains systems to their existing spatial footprint, and environmental awareness (ECO where protection of natural resources is paramount. Very different solutions for all three sets of constraints are identified; some seem slightly implausible (DREAD and all show increased cost (especially in ECO.

What role for microgeneration in a shift to a low carbon domestic energy sector in the UK?

Domestic energy use accounts for more than a quarter of CO2 emissions in the UK. Traditional approaches to energy reduction look at direct emissions savings, and recommend insulation and efficiency as more cost-effective than microgeneration. However, microgeneration has indirect, 'soft' benefits and could play a significant role in emissions reduction. Current uptake of microgeneration in the UK is low, with various barriers-economic, technical, cultural, behavioural and institutional-both to uptake and to maximising energy and emissions savings once installed. Subsidies and spreading information alone do not guarantee maximising uptake, and even if successful, this is not enough to maximise savings. The industry focuses on maximising sales, with no incentives to ensure best installations and use; householders do not have access to the best information, and user behaviour does not maximise energy and emission savings. This is related to a broader state of socio-technical 'lock-in' in domestic energy use; there's a lack of connection between personal behaviour and energy consumption, let alone global climate change. This suggests that a major cultural-behavioural shift is needed to reduce energy/emissions in the home. Transition theory and strategic niche management provide insights into possible systemic change and a suitable framework for future policies, such as supporting a variety of radically innovative niches, both technological and social. Microgeneration, properly employed, has the potential to play a part in such a transition by increasing awareness and energy literacy and empowering people to seriously engage in energy debates as producers, as well as consumers, of energy. This deeper understanding and heightened responsibility are crucial in a shift toward bottom-up emission-reducing behaviour change and better acceptance of top-down energy-saving policy measures, as part of a new domestic energy paradigm. The implications for

Nutrition security describes the adequacy of the food supply to meet not only energy but also macronutrient and micronutrient requirements for the population. The aim of this study was to develop a method to assess trends in national nutrition security and the contribution of imports to nutrition security, using the UK as a case study. Food supply data from FAO food balance sheets and national food composition tables were used to estimate the nutrient content of domestically produced food, imported food and exported food. Nutrition security was defined as the total nutrient supply (domestic production, minus exports, plus imports) to meet population-level nutrient requirements. The results showed that the UK was nutrition secure over the period 1961-2011 for energy, macronutrients and key micronutrients, with the exception of total carbohydrates and fibre, which may be due to the loss of fibre incurred by processing cereals into refined products. The supply of protein exceeded population requirements and could be met with domestic production alone. Even excluding all meat there was sufficient protein for population requirements. The supply of total fat, saturated fat and sugar considerably exceeded the current dietary recommendation. As regards nutrition security in 2010, the UK was reliant on imported foods to meet energy, fibre, total carbohydrate, iron, zinc and vitamin A requirements. This analysis demonstrates the importance of including nutrients other than energy to determine the adequacy of the food supply. The methodology also provides an alternative perspective on food security and self-sufficiency by assessing the dependency on imports to meet population level nutritional requirements.

What lessons have been learned in reforming the Renewables Obligation? An analysis of internal and external failures in UK renewable energy policy

2011-01-01

Despite operating a delivery programme for RES-E since 1990, UK targets and policy goals have not been achieved. In response, the Government reformed the RO. This article re-examines UK renewable energy policy by analysing the internal and external failures of the various mechanisms to determine if Government has learnt from previous experience in reforming the RO. Government did not learn from their own actions during the NFFO/RO transition, evidenced by high-levels of similarity in internal/external failures. The reformed-RO is expected to significantly increase deployment, has provided a 'renewables package' by comprehensively addressing both internal/external failures but major internal failures (price/financial risk) still remain, resulting in contiguous failures over two decades and two mechanism changes (NFFO, RO, RO/reformed-RO). Success will again be heavily dependent on a select few technologies and new/untested measures to combat external failures. Mechanism-extension to 2037 is probably the single most important factor underlying potential deployment increases. However, introducing a FIT-like system via the sheer number of 'bolt-on' reforms to counter policy failures indicates loss of direction and clarity. Overall, although Government appears to have learnt some of its lessons from the past two-decades, significant doubt remains whether renewable energy policy objectives will be met via the latest mechanism change. - Research highlights: → Review of UK renewable energy policy learning behaviour via the 2009 Renewable Obligation reform. → Applies key lessons and analysis of NFFO/RO, RO reform and possible FIT schemes. → Finds UK Government has learnt some lessons from the past but some failures remain contiguous over two decades. → In contrast to previous changes, 2009 reform provided a comprehensive reform package. → Significant doubt remains whether objectives will be met via latest mechanism change.

Assessment of Land and Water Resource Implications of the UK 2050 Carbon Plan

Konadu, D. D.; Sobral Mourao, Z.; Skelton, S.; Lupton, R.

2015-12-01

The UK Carbon Plan presents four low-carbon energy system pathways that achieves 80% GHG emission targets by 2050, stipulated in the UK Climate Change Act (2008). However, some of the energy technologies prescribed under these pathways are land and water intensive; but would the increase demand for land and water under these pathways lead to increased competition and stress on agricultural land, and water resources in the UK? To answer the above question, this study uses an integrated modelling approach, ForeseerTM, which characterises the interdependencies and evaluates the land and water requirement for the pathways, based on scenarios of power plant location, and the energy crop yield projections. The outcome is compared with sustainable limits of resource appropriation to assess potential stresses and competition for water and land by other sectors of the economy. The results show the Carbon Plan pathways have low overall impacts on UK water resources, but agricultural land use and food production could be significantly impacted. The impact on agricultural land use is shown to be mainly driven by projections for transport decarbonisation via indigenously sourced biofuels. On the other hand, the impact on water resources is mainly associated with increased inland thermal electricity generation capacity, which would compete with other industrial and public water demands. The results highlight the need for a critical appraisal of UK's long term low-carbon energy system planning, in particular bioenergy sourcing strategy, and the siting of thermal power generation in order to avert potential resource stress and competition.

Spanos, Ioannis; Duckers, Les; Holmes, Kenneth L.

2007-01-01

Current energy trends in UK housing are reviewed and then assessed by introducing the 'CARB financial analysis' methodology. CARB is an acronym for 'Carbon Abatement', as it evaluates the potential carbon-dioxide reduction from different technologies; 'Relative', as all the technologies examined are dependant on various primary sources; and 'Balance', as the cost of surplus CO 2 is quantified. According to conventional financial analysis, most of the technologies examined have the potential to provide positive returns on the investments especially for those with an environmentally conscious agenda. Further reduction of up to 30% of most installed alternative energy systems cost is required to compete with an investment in, e.g., a UK pension scheme. Using the 'CARB financial analysis' the cost of reducing CO 2 has been quantified, and compared with the potential cost of climate change impact. Conventional installed solar technologies are not financially attractive both with a pay back period calculations and 'CARB financial analysis' under current market costs and governmental subsidy regimes. Heat recovery technologies could be sensible investments, both in financial and environmental terms under particular assumptions; especially if the investment budget is small. The use of cogeneration technologies provides a financial advantage in the attempt to minimise the cost of climate change impact, as pay back period of such investment could be less than 7 yr, and the cost of CO 2 saved could be two to seven times less than the global damage cost of carbon emissions.

Micro-generators have the potential to reduce carbon emissions and enhance energy security by providing heat or electricity either from renewable sources, or via the more efficient use of fossil fuels. Such potential is often, however, unquantified or unclear, and hence a thermodynamic and related carbon analysis of micro-generators for UK household energy supply has been performed. Where pertinent, the thermodynamic concept of exergy is employed alongside that of energy. Analysis begins with a description of the established methods of energy supply to, and use within, typical UK households. On these foundations a grid-tied micro-wind turbine, a grid-tied solar photovoltaic array, and a solar hot-water system are analysed. Annual outputs are estimated and contextualised against the demands of representative households. The annual energy-resource and carbon savings provided by the micro-generators are determined on the basis that they (partially) displace the established supply systems. Savings are then compared with the energy-resource and carbon-emission 'debts' of the micro-generators, to assess the latter's net performance. Given appropriate installations, all three micro-generators are found to provide significant net energy and carbon benefits, confirming that all three technologies can provide net reductions in both carbon emissions and dependence on conventional energy resources.

Community Energy Companies in the UK: A Potential Model for Sustainable Development in “Local” Energy?

Directory of Open Access Journals (Sweden)

Séverine Saintier

2017-07-01

Full Text Available The rise of renewable energy sources (RES comes with a shift in attention from government and market energy governance to local community initiatives and self-regulation. Although this shift is generally welcome at domestic and EU level, the regulatory dimension, at both levels, is nevertheless not adapted to this multi-actor market since prosumers are not empowered and energy justice is far from achieved. The rise, in the UK, of Community Interest Companies (consumers and local actors’ collectives in the energy sector provides an interesting perspective as it allows a whole system’s view. Research was conducted with six energy community organizations in the South West of England in order to evaluate their role and identity and assess whether this exemplar of “the rise of a social sphere in regulation” could be used as a model for a more sustainable social approach to the governance of economic relations. Findings illustrate that such organizations undoubtedly play an important role in the renewable energy sector and they also help to alleviate some aspects of “energy injustice”. Yet, the failure to recognize, in terms of energy policy, at domestic and EU level, the importance of such actors undermines their role. The need to embed and support such organizations in policy is necessary if one is to succeed to put justice at the core of the changing energy landscape.

Energy-efficient cooking systems, food-preparation facilities, and human diets

Energy Technology Data Exchange (ETDEWEB)

Newborough, M.

1987-01-01

This thesis aims at identifying the opportunities for saving energy, which are available to those working within the final link of the UK food system (i.e., at, or in relation to, the points of consumption). Substantial prospective savings exist, because relatively little attention has, as yet, been given to energy-thrift in food-preparation facilities. Within the food-service industry, cooking systems are characterized by high thermal capacities, excessive external surface temperatures and poorly-designed control systems. Catering staff, who use such appliances, are rarely trained to use energy wisely when preparing foods, and kitchens (and their associated dining facilities) tend to be designed without sufficient regard to energy-thrift. Similar problems prevail in domestic kitchens, but to a lesser extent because the cooks there usually pay (or contribute towards) the fuel bills. However, manufacturers still provide household appliances, which are unnecessarily energy-profligate. Furthermore most people have insufficient knowledge of the nutritional suitabilities and the primary-energy costs of their diets. Thus a major educational need exists, which must be satisfied if industrialized food systems are to become more energy efficient.

Highlights: • We study three open cycle Th–U-fuelled nuclear energy systems. • Comparison of these systems is made to a reference U-fuelled EPR. • Fuel cycle modelling is performed with UK NNL code “ORION”. • U-fuelled system is economically favourable and needs least separative work per kWh. • Th–U-fuelled systems offer negligible waste and proliferation resistance advantages. - Abstract: In this study, we have sought to determine the advantages, disadvantages, and viability of open cycle thorium–uranium-fuelled (Th–U-fuelled) nuclear energy systems. This has been done by assessing three such systems, each of which requires uranium enriched to ∼20% 235 U, in comparison to a reference uranium-fuelled (U-fuelled) system over various performance indicators, spanning material flows, waste composition, economics, and proliferation resistance. The values of these indicators were determined using the UK National Nuclear Laboratory’s fuel cycle modelling code ORION. This code required the results of lattice-physics calculations to model the neutronics of each nuclear energy system, and these were obtained using various nuclear reactor physics codes and burn-up routines. In summary, all three Th–U-fuelled nuclear energy systems required more separative work capacity than the equivalent benchmark U-fuelled system, with larger levelised fuel cycle costs and larger levelised cost of electricity. Although a reduction of ∼6% in the required uranium ore per kWh was seen for one of the Th–U-fuelled systems compared to the reference U-fuelled system, the other two Th–U-fuelled systems required more uranium ore per kWh than the reference. Negligible advantages and disadvantages were observed for the amount and the properties of the spent nuclear fuel (SNF) generated by the systems considered. Two of the Th–U-fuelled systems showed some benefit in terms of proliferation resistance of the SNF generated. Overall, it appears that there is little

2007-07-01

In October 2006 the UK government published a new Local Government White Paper. This policy statement set the framework for the role of local government in the coming years.The White Paper is one stage in the latest wave of local government reform in the UK. This reform has aimed to refocus attention away from delivery of specific services and towards community leadership, particularly with reference to sustainable development. Climate change is given some emphasis within the White Paper, and should become one of the indicators against which local government performance is measured.This paper examines energy action in local authorities in the past few years, in a situation where most, but not all, were still strongly focused on service delivery. By contrasting this with the results achieved in authorities that have taken a community leadership role, the paper examines the potential of the White Paper. It addresses the following questions: does local government have the capacity to deliver increased local action on climate change? Does the UK policy framework support and encourage development and deployment of this capacity? And do the national and regional bodies that provide support for local authorities need to change the services they offer in light of recent policy developments?.

DOES ENERGY CONSUMPTION VOLATILITY AFFECT REAL GDP VOLATILITY? AN EMPIRICAL ANALYSIS FOR THE UK

Directory of Open Access Journals (Sweden)

Abdul Rashid

2013-10-01

Full Text Available This paper empirically examines the relation between energy consumption volatility and unpredictable variations in real gross domestic product (GDP in the UK. Estimating the Markov switching ARCH model we find a significant regime switching in the behavior of both energy consumption and GDP volatility. The results from the Markov regime-switching model show that the variability of energy consumption has a significant role to play in determining the behavior of GDP volatilities. Moreover, the results suggest that the impacts of unpredictable variations in energy consumption on GDP volatility are asymmetric, depending on the intensity of volatility. In particular, we find that while there is no significant contemporaneous relationship between energy consumption volatility and GDP volatility in the first (low-volatility regime, GDP volatility is significantly positively related to the volatility of energy utilization in the second (high-volatility regime.

Developing a sustainable energy strategy for a water utility. Part I: A review of the UK legislative framework.

Increasing political effort to improve water quality across the UK and Europe has led to water and sewerage companies investing heavily in high-tech wastewater treatment plants capable of producing high quality effluents. Consequently, amounts of bought-in electricity used for wastewater treatment has and will continue to increase significantly over coming years, while greater provision of enhanced sewage treatment also produces greater volumes of sewage sludge requiring treatment and disposal. Over the same period, tougher controls on the quality of biosolids applied to agricultural land have also been introduced, while there has been an international attempt to reduce the use of fossil-fuel derived power sources because of concerns over global warming. The latter has brought about the introduction of financial instruments, such as the Climate Change Levy, to curb energy use, promote energy efficiency and encourage the development of renewable energy technologies. These factors are set to drive-up the costs of providing adequate sewage treatment services, while at the same time, a tough regulatory line taken to control profits on regional monopolies held by the UK water companies will significantly reduce their revenues over the period 2000-05. The result is that, financially, UK water and sewerage companies face their most challenging period since privatisation in 1989. This paper briefly outlines the current regulations relating to water quality and energy use that will affect water company operations over coming years.

UK experience of planning the nuclear contribution to the UK power programme

Catchpole, S.; Jenkin, F.P.

1977-01-01

The paper outlines U.K. experience in planning nuclear programmes. It examines the factors which have determined the size of such programmes together with those factors which have influenced their implementation. The paper also discusses the role which the utility has played in the deployment of nuclear power in the U.K. At present, nuclear energy can only be utilised on a large scale via the electricity route and the forecasting of electricity demand is therefore a key element in determining the size of the nuclear programme. Other important issues which affect the nuclear contribution are: national fuel policies, discontinuities in price and availability of imported fossil fuels, plant capital costs, fuel price relativities, plant siting, rate of introduction of new nuclear systems, manufacturer's capability, public attitudes towards nuclear power and financing. These issues are dealt with in some detail including their relative importance in the U.K. The paper also discusses the contribution of the various nuclear bodies in the U.K. in securing the implementation of the nuclear programmes. From the inception of nuclear power in the U.K., it has been recognised that a major utility has a central role to play not only in commercial operation but also in the procurement of plant and materials. As explained in the paper this ''informed buyer'' approach, which is being increasingly adopted by other major utilities, calls for an organisation and technical infrastructure far more complex than is the case for fossil plants. The requirements of safety, which is unambiguously the responsibility of the utility, and of high availability of plant operation demand a rigorous approach to design, quality assurance, project management, construction and operation. To this must be added sound research and development and staff training facilities. The paper explains how experience in these vital areas has been built up

Turning lights into flights: Estimating direct and indirect rebound effects for UK households

International Nuclear Information System (INIS)

Chitnis, Mona; Sorrell, Steve; Druckman, Angela; Firth, Steven K.; Jackson, Tim

2013-01-01

Energy efficiency improvements by households lead to rebound effects that offset the potential energy and emissions savings. Direct rebound effects result from increased demand for cheaper energy services, while indirect rebound effects result from increased demand for other goods and services that also require energy to provide. Research to date has focused upon the former, but both are important for climate change. This study estimates the combined direct and indirect rebound effects from seven measures that improve the energy efficiency of UK dwellings. The methodology is based upon estimates of the income elasticity and greenhouse gas (GHG) intensity of 16 categories of household goods and services, and allows for the embodied emissions of the energy efficiency measures themselves, as well as the capital cost of the measures. Rebound effects are measured in GHG terms and relate to the adoption of these measures by an average UK household. The study finds that the rebound effects from these measures are typically in the range 5–15% and arise mostly from indirect effects. This is largely because expenditure on gas and electricity is more GHG-intensive than expenditure on other goods and services. However, the anticipated shift towards a low carbon electricity system in the UK may lead to much larger rebound effects. - Highlights: ► We estimate the direct and indirect rebound effects from energy efficiency improvements by UK households. ► We allow for the capital cost of the improvement, together with the emissions embodied in the relevant equipment. ► We find rebound effects to be relatively modest, in the range 5–15%. ► The anticipated shift towards a low carbon electricity system will lead to larger rebound effects

The UK transport carbon model: An integrated life cycle approach to explore low carbon futures

2012-01-01

Current debate focuses on the need for the transport sector to contribute to more ambitious carbon emission reduction targets. In the UK, various macro-economic and energy system wide, top-down models are used to explore the potential for energy demand and carbon emissions reduction in the transport sector. These models can lack the bottom-up, sectoral detail needed to simulate the effects of integrated demand and supply-side policy strategies to reduce emissions. Bridging the gap between short-term forecasting and long-term scenario “models”, this paper introduces a newly developed strategic transport, energy, emissions and environmental impacts model, the UK Transport Carbon Model (UKTCM). The UKTCM covers the range of transport–energy–environment issues from socio-economic and policy influences on energy demand reduction through to life cycle carbon emissions and external costs. The model is demonstrated in this paper by presenting the results of three single policies and one policy package scenario. Limitations of the model are also discussed. Developed under the auspices of the UK Energy Research Centre (UKERC) the UKTCM can be used to develop transport policy scenarios that explore the full range of technological, fiscal, regulatory and behavioural change policy interventions to meet UK climate change and energy security goals. - Research highlights: ►New strategic transport, energy, emissions and environmental impacts model. ►Tool to develop and analyse full consequences of multiple scenarios of transport policy packages. ►Novel approach to modelling demand for new vehicles by market and technology. ►Model available for use by research community via http://www.ukerc.ac.uk/support/tiki-index.php?page=UK+Transport+Carbon+Model.

From laggard to leader: Explaining offshore wind developments in the UK

Kern, Florian; Smith, Adrian; Shaw, Chris; Raven, Rob; Verhees, Bram

2014-01-01

Offshore wind technology has recently undergone rapid deployment in the UK. And yet, up until recently, the UK was considered a laggard in terms of deploying renewable energy. How can this burst of offshore wind activity be explained? An economic analysis would seek signs for newfound competitiveness for offshore wind in energy markets. A policy analysis would highlight renewable energy policy developments and assess their contribution to economic prospects of offshore wind. However, neither perspective sheds sufficient light on the advocacy of the actors involved in the development and deployment of the technology. Without an account of technology politics it is hard to explain continuing policy support despite rising costs. By analysing the actor networks and narratives underpinning policy support for offshore wind, we explain how a fairly effective protective space was constructed through the enroling of key political and economic interests. - Highlights: • UK is world leader in offshore wind deployment. • Article explains boom in deployment by looking at the politics of renewable energy policy. • Offshore wind is supported by a variety of actors with aligned political and economic interests. • Analysis highlights the importance of a system builder

Perspectives of nuclear power in the UK - the view of a utility

International Nuclear Information System (INIS)

Golby, P.

2007-01-01

Nuclear energy is back on the agenda in UK due to the discussion about climate change and security of supply. First, the UK has to face up to the challenges of reducing its greenhouse gas emissions. The UK Government has adopted a clear leadership position on climate change internationally. Second, UK is facing some fundamental questions about the future security of the energy supplies. The decline of UKs' gas reserves in the North Sea is bringing to an end the years in which the UK could afford to be relatively relaxed energy and energy policy almost took care of itself. We are expecting the next major milestone with the UK Government due to publish an 'Energy Withe Paper'. Alongside that document they are also due to launch a new consultation on nuclear power and whether it should have a role in the UK market. For investment in nuclear to be a credible economic option for investors a number of issues will need to be addressed by the UK Government. These issues include the public and political acceptance, the management of the waste by the Government, and an efficient regulatory and licensing framework for new plants. Two words should be addressed to the UK Government at the moment - urgency and partnership. Urgency - because we desperately need to see progress on energy policy over the next 12 months. It is 5 minutes to midnight and the clock is ticking. Partnership - because investors are ready to make the necessary investments but we need in the UK the long-term policy framework that will underpin and support the scale of the investment we need to see.

The effect of fossil energy and other environmental taxes on profit incentives for change in an open economy: Evidence from the UK

International Nuclear Information System (INIS)

Webster, Allan; Ayatakshi, Sukanya

2013-01-01

This paper argues that the underlying supply and demand analysis of fossil energy and other environmental taxes needs further elaboration when a country (a) introduces national fossil energy or environmental taxes and (b) is open to international trade at given world prices. We provide evidence that such conditions are plausible for many sectors in the UK. A key implication is that the short run effects of such taxes should not be felt in final good prices, since these are determined in world markets, but in terms of underlying profitability. These changes in underlying profits provide two key incentives for producers—to change to more environmentally friendly production techniques and to switch resources to production of less environmentally harmful goods. Using input—output techniques we provide evidence for the UK to show how existing fossil energy and other “green” taxes have affected underlying profitability. The evidence shows quite strong profit incentives to shift resources from a small number of energy intensive industries to others. - Highlights: • Energy taxes affect profits more than prices for sectors trading at world prices. • This study suggests that many sectors in the UK satisfy these conditions. • Our evidence suggests that few sectors are strongly affected by energy taxes. • Energy taxes have a strong effect relative to other possible environmental taxes

Hybrid PV and solar-thermal systems for domestic heat and power provision in the UK: Techno-economic considerations

Herrando, María; Markides, Christos N.

2016-01-01

Highlights: • Renewable heat and power generation in UK homes with PVT systems studied. • PVT/w generation: 2.3 MW_e h/yr (51% of demand) and 1.0 MW_t_h h/yr (36% hot water). • Optimised PVT/w system has 9–11 year payback periods (PV-only: 6.8 years). • Same system allows 16.0-t CO_2 reduction and 14-t primary fossil-fuel saving. • With a ∼2:1 support (£/W_e h:£/W_t_h h), PVT and PV have similar payback periods. - Abstract: A techno-economic analysis is undertaken to assess hybrid PV/solar-thermal (PVT) systems for distributed electricity and hot-water provision in a typical house in London, UK. In earlier work (Herrando et al., 2014), a system model based on a PVT collector with water as the cooling medium (PVT/w) was used to estimate average year-long system performance. The results showed that for low solar irradiance levels and low ambient temperatures, such as those associated with the UK climate, a higher coverage of total household energy demands and higher CO_2 emission savings can be achieved by the complete coverage of the solar collector with PV and a relatively low collector cooling flow-rate. Such a PVT/w system demonstrated an annual electricity generation of 2.3 MW h, or a 51% coverage of the household’s electrical demand (compared to an equivalent PV-only value of 49%), plus a significant annual water heating potential of to 1.0 MW h, or a 36% coverage of the hot-water demand. In addition, this system allowed for a reduction in CO_2 emissions amounting to 16.0 tonnes over a life-time of 20 years due to the reduction in electrical power drawn from the grid and gas taken from the mains for water heating, and a 14-tonne corresponding displacement of primary fossil-fuel consumption. Both the emissions and fossil-fuel consumption reductions are significantly larger (by 36% and 18%, respectively) than those achieved by an equivalent PV-only system with the same peak rating/installed capacity. The present paper proceeds further, by

Nuclear power and the UK

International Nuclear Information System (INIS)

Murphy, St.

2009-01-01

This series of slides describes the policy of the UK government concerning nuclear power. In January 2008 the UK Government published the White Paper on the Future of Nuclear Power. The White Paper concluded that new nuclear power stations should have a role to play in this country's future energy mix. The role of the Government is neither to build nuclear power plants nor to finance them. The White Paper set out the facilitative actions the Government planned to take to reduce regulatory and planning risks associated with investing in new nuclear power stations. The White Paper followed a lengthy period of consultation where the UK Government sought a wide variety of views from stakeholders and the public across the country on the future of nuclear power. In total energy companies will need to invest in around 30-35 GW of new electricity generating capacity over the next two decades. This is equivalent to about one-third of our existing capacity. The first plants are expected to enter into service by 2018 or sooner. The Office for Nuclear Development (OND) has been created to facilitate new nuclear investment in the UK while the Nuclear Development Forum (NDF) has been established to lock in momentum to secure the long-term future of nuclear power generation in the UK.

Greenhalgh, Christine; Azapagic, Adisa

2009-01-01

There has been resurgence in interest in new nuclear power stations over the last couple of years. The UK Government has taken steps to encourage the private sector to build new stations in the UK, a change in its previous neutral stance toward nuclear power. This paper examines the change in government policy asking what drivers have led to this decision and what barriers were preventing new nuclear power in the past and what barriers are still faced by both government and industry. Three main drivers are discussed: security of energy supply; diminishing energy generation capacity; and climate change. The paper also examines other key factors that play a part in facilitating a shift in government policy, namely economics, public perception and waste management policy. Barriers are identified through examination of public perception, and policy. The changes to the planning system are also discussed. The paper concludes by comparing drivers and barriers for other technologies and contrasting the UK experience with that of other countries.

Levelised costs of Wave and Tidal energy in the UK: Cost competitiveness and the importance of 'banded' Renewables Obligation Certificates

Allan, Grant; Gilmartin, Michelle; McGregor, Peter; Swales, Kim

2011-01-01

In this paper, publicly available cost data are used to calculate the private levelised costs of two marine energy technologies for UK electricity generation: Wave and Tidal Stream power. These estimates are compared to those for ten other electricity generation technologies whose costs were identified by the UK Government (). Under plausible assumptions for costs and performance, point estimates of the levelised costs of Wave and Tidal Stream generation are Pounds 190 and Pounds 81/MWh, respectively. Sensitivity analysis shows how these relative private levelised costs calculations are affected by variation in key parameters, specifically the assumed capital costs, fuel costs and the discount rate. We also consider the impact of the introduction of technology-differentiated financial support for renewable energy on the cost competitiveness of Wave and Tidal Stream power. Further, we compare the impact of the current UK government support level to the more generous degree of assistance for marine technologies that is proposed by the Scottish government. - Research highlights: → Levelised costs of electricity generation from wave and tidal stream in UK calculated. → Comparison to ten renewable and non-renewable technologies demonstrated. → Sensitivity of levelised costs to key assumptions is demonstrated. → Technology-specific financial support revealed to be insufficient at current costs.

Directory of Open Access Journals (Sweden)

Mark Dowson

2014-10-01

Full Text Available There is an opportunity to improve the efficiency of passive Trombe walls and active solar air collectors by replacing their conventional glass covers with lightweight polycarbonate panels filled with nanoporous aerogel insulation. This study investigates the thermal performance, energy savings, and financial payback period of passive Aerogel Trombe walls applied to the existing UK housing stock. Using parametric modeling, a series of design guidance tables have been generated, providing estimates of the energy savings and overheating risk associated with applying areas of Trombe wall to four different house types across the UK built to six notional construction standards. Calculated energy savings range from 183 kWh/m2/year for an 8 m2 system retrofitted to a solid walled detached house to 62 kWh/m2/year for a 32 m2 system retrofitted to a super insulated flat. Predicted energy savings from Trombe walls up to 24 m2 are found to exceed the energy savings from external insulation across all house types and constructions. Small areas of Trombe wall can provide a useful energy contribution without creating a significant overheating risk. If larger areas are to be installed, then detailed calculations would be recommended to assess and mitigate potential overheating issues.

Computer modelling of the UK wind energy resource. Phase 2. Application of the methodology

This report presents the results of the second phase of a programme to estimate the UK wind energy resource. The overall objective of the programme is to provide quantitative resource estimates using a mesoscale (resolution about 1km) numerical model for the prediction of wind flow over complex terrain, in conjunction with digitised terrain data and wind data from surface meteorological stations. A network of suitable meteorological stations has been established and long term wind data obtained. Digitised terrain data for the whole UK were obtained, and wind flow modelling using the NOABL computer program has been performed. Maps of extractable wind power have been derived for various assumptions about wind turbine characteristics. Validation of the methodology indicates that the results are internally consistent, and in good agreement with available comparison data. Existing isovent maps, based on standard meteorological data which take no account of terrain effects, indicate that 10m annual mean wind speeds vary between about 4.5 and 7 m/s over the UK with only a few coastal areas over 6 m/s. The present study indicates that 28% of the UK land area had speeds over 6 m/s, with many hill sites having 10m speeds over 10 m/s. It is concluded that these `first order` resource estimates represent a substantial improvement over the presently available `zero order` estimates. The results will be useful for broad resource studies and initial site screening. Detailed resource evaluation for local sites will require more detailed local modelling or ideally long term field measurements. (12 figures, 14 tables, 21 references). (Author)

Towards a synthesised network approach: An analysis of UK nuclear and renewable (wave) energy programme 1939-1985

International Nuclear Information System (INIS)

Watt, R.N.

1998-05-01

This thesis is concerned with two broad areas of interest: network interpretations of policy processes and alternative sources of energy. All three network interpretations examined (policy networks, actor networks and advocacy coalitions) stress different variables when examining policy processes. Equally, each can be criticised for over-emphasising their chosen variable. However, I shall argue that these flaws do not constitute grounds for dismissing any of these approaches. Several authors have suggested that we combine the merits of these network approaches but so far this has not been attempted. A central aim of this thesis is to develop a synthesis of the merits of each network approach which I argue offers a more robust means of interpreting policy processes. These ideas are then applied to an examination of the relationship between the UK civil nuclear programme (1939-1985) and the UK wave energy programme (1974-1985). Existing literature argues that the nuclear establishment used its considerable influence to undermine the wave energy programme. With the aid of a synthesised network approach, I argue that the nuclear conspiracy narrative is an over-simplification of this particular policy process. (author)

Energy recovery from municipal solid waste plays a key role in sustainable waste management and energy security. However, there are numerous technologies that vary in suitability for different economic and social climates. This study sets out to develop and apply a multi-criteria decision making methodology that can be used to evaluate the trade-offs between the benefits, opportunities, costs and risks of alternative energy from waste technologies in both developed and developing countries. The technologies considered are mass burn incineration, refuse derived fuel incineration, gasification, anaerobic digestion and landfill gas recovery. By incorporating qualitative and quantitative assessments, a preference ranking of the alternative technologies is produced. The effect of variations in decision criteria weightings are analysed in a sensitivity analysis. The methodology is applied principally to compare and assess energy recovery from waste options in the UK and India. These two countries have been selected as they could both benefit from further development of their waste-to-energy strategies, but have different technical and socio-economic challenges to consider. It is concluded that gasification is the preferred technology for the UK, whereas anaerobic digestion is the preferred technology for India. We believe that the presented methodology will be of particular value for waste-to-energy decision-makers in both developed and developing countries. Copyright © 2015 Elsevier Ltd.

The Importance of Heating System Transient Response in Domestic Energy Labelling

Directory of Open Access Journals (Sweden)

George Bennett

2016-08-01

Full Text Available European National Calculation Methods (NCM, such as the UK Standard Assessment Procedure (SAP, are used to make standardised and simplified assessments of building energy performance. These NCMs contain simplifications to aid ease of use and comparability of resulting Energy Performance Certificates (EPC. By comparing SAP with a modern, dynamic modelling system, this study quantifies internal temperatures and thereby heating energy consumption. Results show that for the considered test house SAP results correspond closely to a dynamic model using an idealistic heating system, with perfect control and instant responsiveness. However, the introduction of a dynamic, physically realistic gas fired boiler and water based heating system to the model results in a consistent increase in internal temperature (0.5 °C and energy demand (by ca. 1000 kWh/a. Variation of further parameters within the dynamic model, controls and heat source size, are presented and compared to SAP results and assumptions. The inclusion of more realistic dynamics in building energy modelling for NCMs may provide a better basis for effective decision making with respect to a wide range of heating systems.

To achieve the CO{sub 2} reductions deemed necessary to limit the impact of adverse climate change will require real changes in the way we both use and supply energy. Although explicit international and national frameworks are necessary to facilitate reduction strategies, regional implementation and local initiatives are increasingly seen as having an important role to play, both in meeting national CO{sub 2} reduction targets and improving the local environment. This paper deals with supply side of the energy equation for Greater Manchester in the U.K., examining the potential for 'regional' energy supply options to contribute to a reduction in carbon intensity. By assessing actual and latent regional opportunities, the potential for achieving a more sustainable energy supply system is evaluated. (Author)

The effects of changes in the UK energy demand and environmental legislation on atmospheric pollution by carbon dioxide

Blakemore, F.B.; Davies, C.; Isaac, J.G.

1998-01-01

It has been demonstrated that the combustion of fossil fuel accounts for 97% of the carbon dioxide generated in the UK. The demand for primary energy over the 1970-1994 period has only marginally increased, however the demand for natural gas, which has a significantly lower carbon content per unit of energy than other fuels, accounts largely for the lowering of carbon dioxide emissions. The enactment UK/EU Environmental Legislation coupled with World Agreements accounts for a significant lowering of carbon dioxide emissions over this period. Future predictions suggest that a further downturn in carbon dioxide emissions will take place over the 1990-2000 period, followed by a pronounced increase over the 2000-2020 period. The expansion of the use of CCGT and/or the introduction of the IGCC and the SUPC in the power generating sector provides an opportunity for a further reduction in carbon dioxide emissions. (author)

Overall we believe the project has been successful in its aim to increase the volume of biomass heating enquiries and enable greater use of the industry 'knowledge base'. Throughout the duration of the project a number of new biomass heating systems have been installed, including Shenstone Lodge School, Boughton Pumping Station and Elvendon Priory. In addition, an efficient system of information exchange has been established for customers and industry. British BioGen believe that the benefits of this system will be a crucial factor in achieving bioenergy industry targets of 2MWt for domestic heating, 2MWt for industrial and commercial heating and 2MWt for CHP by the end of 2001. The remainder of this summary offers highlights of the activities undertaken within the project, outlines the conclusions of the project and makes brief recommendations for further actions to assist the further deployment of biomass heating in the UK.

Blair`s cabinet of the UK, as soon as it was formed, started a review of all policies of the past Conservative government, including the area of energy and environment. The Labour Party has already underlined its commitment to promoting petroleum substituting, i.e., renewable energy. The government made clear that the unique British NFFO Scheme to promote sources of renewable energy would continue and in November, 1997 published the policy guide for the fifth round of NFFO bidding. The British energy market is generally considered to be the most liberalized for free competition in Europe and even the retail market for households is going to be completely open for competition in electricity and gas supply by 1998. As to the regulation of the green house gas exhaust, the Labour Party has put forward a target to cut 20% of the exhaust level of 1990 by the year 2010. The government is now preparing measures for its implementation. At present, the EU is debating the draft of the landfill directive. In the UK, the construction of waste incineration and power generating plants with modern technology is now being promoted. 27 tabs.

2002-07-01

The document makes a case for the development of a design of wood chip stoker-burner more suited to the UK than those currently imported from Sweden and Finland. The differences would centre on market conditions, performance and cost-effectiveness and the devices would be manufactured or part-manufactured in the UK. Econergy Limited was contracted by the DTI as part of its Sustainable Energy Programmes to design and construct an operational prototype stoker-burner rated at 120 kWth. A test rig was built to: (i) study modified burner heads and (ii) develop control hardware and a control strategy. Both (i) and (ii) are described. Tests brought about an increase in performance of the burner head and its wet wood performance. It was considered that further improvements are achievable and six areas for future study were suggested.

Climate change, energy security, and risk-debating nuclear new build in Finland, France and the UK

2011-01-01

Concerns about climate change and energy security have been major arguments used to justify the recent return of nuclear power as a serious electricity generation option in various parts of the world. This article examines the recent public discussion in Finland, France, and the UK - three countries currently in the process of constructing or planning new nuclear power stations. To place the public discussion on nuclear power within the relationship between policy discourses and contexts, the article addresses three interrelated themes: the justifications and discursive strategies employed by nuclear advocates and critics, the similarities and differences in debates between the three countries, and the interaction between the country-specific state orientations and the argumentation concerning nuclear power. Drawing from documentary analysis and semi-structured interviews, the article identifies and analyses key discursive strategies and their use in the context of the respective state orientations: 'technology-and-industry-know-best' in Finland, 'government-knows-best' in France, and 'markets-know-best' in the UK. The nuclear debates illustrate subtle ongoing transformations in these orientations, notably in the ways in which the relations between markets, the state, and civil society are portrayed in the nuclear debates. - Highlights: → Focus on argumentation on new nuclear power in Finland, France, and the UK. → Nuclear power is justified by climate change, energy security, and independence. → The credibility of discursive strategies varies across countries. → Country-specific state orientations shape the success of discursive strategies. → Discursive strategies contain normative claims about state-society relations.

Modeling and analysis of renewable energy obligations and technology bandings in the UK electricity market

International Nuclear Information System (INIS)

Gürkan, Gül; Langestraat, Romeo

2014-01-01

In the UK electricity market, generators are obliged to produce part of their electricity with renewable energy resources in accordance with the Renewable Obligation Order. Since 2009 technology banding has been added, meaning that different technologies are rewarded with a different number of certificates. We analyze these two different renewable obligation policies in a mathematical representation of an electricity market with random availabilities of renewable generation outputs and random electricity demand. We also present another, alternative, banding policy. We provide revenue adequate pricing schemes for the three obligation policies. We carry out a simulation study via sampling. A key finding is that the UK banding policy cannot guarantee that the original obligation target is met, hence potentially resulting in more pollution. Our alternative provides a way to make sure that the target is met while supporting less established technologies, but it comes with a significantly higher consumer price. Furthermore, as an undesirable side effect, we observe that a cost reduction in a technology with a high banding (namely offshore wind) leads to more CO 2 emissions under the UK banding policy and to higher consumer prices under the alternative banding policy. - Highlights: • We model and analyze three renewable obligation policies in a mathematical framework. • We provide revenue adequate pricing schemes for the three policies. • We carry out a simulation study via sampling. • The UK policy cannot guarantee that the original obligation target is met. • Cost reductions can lead to more pollution or higher prices under banding policies

Full Text Available This paper investigates whether, and if so, how procedural fairness affects performance evaluation system satisfaction in a UK Police Force. Employing a survey method with samples of detective inspectors and detective chief inspectors with significant managerial responsibilities in a UK Police Force, this study finds that procedural fairness affects performance evaluation system satisfaction. Further analysis reveals that the effect of procedural fairness on performance evaluation system satisfaction is mediated by trust. This study provides empirical evidence on how procedural fairness affects performance evaluation system satisfaction. The results of this study may benefit the designer of performance evaluation systems in police organizations.

Passive House and Low Energy Buildings: Barriers and Opportunities for Future Development within UK Practice

Directory of Open Access Journals (Sweden)

Adrian Pitts

2017-02-01

Full Text Available This paper describes research carried out to understand better the current and future emphases emerging from practice for the design and development of “Passive House” and low energy buildings. The paper initially discusses the extant position, particularly with regards to the UK and considers how regulation and assessment systems have changed in recent years, as well as projecting ideas forward taking account of contemporary political situations. Relevant previous research into Passive House and low energy design and construction is then reviewed. The need for greater understanding of professionals and their communication/collaboration with clients were identified as important factors impacting development. Those involved in the design and construction practice therefore have key roles in the process of enhancing energy efficiency. Five industry/practice based professional organizations were interviewed in-depth to gain insights into their experience of current low energy design, and to extrapolate the outcomes to future scenarios. The method employed used a structured interview technique with key question areas to lead the discussion. The anonymized responses discussed are grouped around key themes. Evidence suggests there has been a move towards the adoption of voluntary high level standards because of potential limitations with mandatory regulations and because of perceived additional benefits of higher quality design. This change is now more than previously, being driven by informed clients, design professionals, and the industry, with regulation taking a secondary role. New opportunities and barriers are becoming evident and these require further consideration.

Estimating the CO2 mitigation potential of horizontal Ground Source Heat Pumps in the UK

By 2020, the UK will need to generate 15% of its energy from renewables to meet our contribution to the EU renewable energy target. Heating and cooling systems of buildings account for 30%-50% of the global energy consumption; thus, alternative low-carbon technologies such as horizontal Ground Couple Heat Pumps (GCHPs) can contribute to the reduction of anthropogenic CO2 emissions. Horizontal GCHPs currently represent a small fraction of the total energy generation in the UK. However, the fact that semi-detached and detached dwellings represent approximately 40% of the total housing stocks in the UK could make the widespread implementation of this technology particularly attractive in the UK and so could significantly increase its renewable energy generation potential. Using a simulation model, we analysed the dynamic interactions between the environment, the horizontal GCHP heat exchanger and typical UK dwellings, as well as their combined effect on heat pump performance and CO2 mitigation potential. For this purpose, a land surface model (JULES, Joint UK Land Environment Simulator), which calculates coupled soil heat and water fluxes, was combined with a heat extraction model. The analyses took into account the spatio-temporal variability of soil properties (thermal and hydraulic) and meteorological variables, as well as different horizontal GCHP configurations and a variety of building loads and heat demands. Sensitivity tests were performed for four sites in the UK with different climate and soil properties. Our results show that an installation depth of 1.0m would give us higher heat extractions rates, however it would be preferable to install the pipes slightly deeper to avoid the seasonal influence of variable meteorological conditions. A value of 1.5m for the spacing between coils (S) for a slinky configuration type is recommended to avoid thermal disturbances between neighbouring coils. We also found that for larger values of the spacing between the coils

In October 2006 the UK government published a new Local Government White Paper. This policy statement set the framework for the role of local government in the coming years.The White Paper is one stage in the latest wave of local government reform in the UK. This reform has aimed to refocus attention away from delivery of specific services and towards community leadership, particularly with reference to sustainable development. Climate change is given some emphasis within the White Paper, and should become one of the indicators against which local government performance is measured.This paper examines energy action in local authorities in the past few years, in a situation where most, but not all, were still strongly focused on service delivery. By contrasting this with the results achieved in authorities that have taken a community leadership role, the paper examines the potential of the White Paper. It addresses the following questions: does local government have the capacity to deliver increased local action on climate change? Does the UK policy framework support and encourage development and deployment of this capacity? And do the national and regional bodies that provide support for local authorities need to change the services they offer in light of recent policy developments?.

The value of social networks in the diffusion of energy-efficiency innovations in UK households

International Nuclear Information System (INIS)

McMichael, Megan; Shipworth, David

2013-01-01

The UK Government has policy goals for increasing energy efficiency in existing homes. However, there are doubts that standard technology and behavioural innovations will be adopted widely enough in time to achieve the targets. Diffusion of innovation theory states that the communication of information on innovations through a social system encourages adoption. Social capital theory states that interpersonal communication is a key means of gaining resources, such as information on energy-efficiency innovations, for attaining certain goals. Case study research of three British communities was conducted in 2009 in order to understand the influence of social capital on information diffusion regarding the adoption of household energy-efficiency measures. The findings show that while standard campaigns may account for two-thirds of information-seeking behaviour, they may not be addressing up to one-third of information-seekers who would prefer to speak to people they know. Findings also indicate that seeking information amongst personal contacts is often associated with adoption of energy-efficiency innovations, increasing the likelihood of adoption by up to four times, but that there are important differences between types of innovations and communities. Tailoring campaigns to communities' communication channels is therefore imperative. These findings have important implications for informing community-based energy-efficiency programmes. - Highlights: ► Case study research suggests social capital is important for home energy innovations. ► One-third of respondents indicated a preference for speaking to people they know. ► Those who sought information were up to four times more likely to adopt innovations. ► Results varied by innovation and by each community case study. ► Tailoring campaigns to communities' communication channels is imperative.

To investigate the sugar, energy and caffeine content of sugar-sweetened drinks marketed and consumed as energy drinks available in the UK. We carried out a cross-sectional survey in 2015 and 2017 of energy drinks available in the main UK retailers. The sugar (sugars g/100 mL), energy (kcal/100 mL), caffeine (mg/100 mL) and serving size were collected from product packaging and nutrition information panels of energy drinks available in the nine main UK grocery retailers, three health and beauty retailers and one convenience store. The number of formulations (per 100 mL) and number of products (per serving) have fallen (from 75 to 49 and from 90 to 59) between 2015 and 2017, respectively. Energy drinks surveyed showed a 10% reduction in sugar, from 10.6 to 9.5 g/100 mL (P=0.011) and a 6% reduction in energy content (P=0.005) per 100 mL between 2015 and 2017. The average caffeine content of energy drinks, with a warning label, has remained high at 31.5±0.9 in 2015 and 31.3±1.0 mg/100 mL in 2017. Despite there being reductions, sugar, energy and caffeine content remain at concerning levels in 2017. To reduce the harmful impact of energy drinks, further reduction in sugar and a reduction in caffeine by reformulation are urgently needed. Other measures such as ban on the sale of energy drinks to children and smaller product sizes should also be explored, while warning labels should be kept. A reduction in sugar, energy and caffeine content and overall energy drinks consumption could be beneficial in reducing sugar, energy and caffeine intake of consumers of energy drinks. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Altering existing buildings in the UK

International Nuclear Information System (INIS)

Roberts, Simon

2008-01-01

The profiles of both existing housing and existing public and commercial buildings show that many have very poor thermal efficiency. The UK housing stock is replaced at a low rate of about 1% a year, so to cut energy use it is essential to address the challenges of existing buildings. This will involve reducing energy demand through passive measures such as retrofitted insulation, replacement of windows and proper airtightness, while ensuring adequate ventilation. Active measures include upgrading improved boilers and adding locally produced energy from wind, biomass, solar power and other sources. The introduction of Display Energy Certificates will increase energy awareness but there will also need to be a programme of increased demolition for the worst-performing homes. In addition, buildings will need to be adapted to cope with worse weather, higher temperatures and increased flood risk as climate change takes effect. Overheating, rather than excessive cold, is set to become a growing problem for householders and employees in existing UK buildings

Transition pathways for a UK low carbon electricity future

Foxon, Timothy J.

2013-01-01

Achieving long-term targets for greenhouse gas emissions reductions, such as the UK's legally-binding target of reducing its emissions by 80% by 2050, will require a transition in systems for meeting and shaping energy service demands, involving radical substitution to low-carbon supply technologies and improvements in end-use energy efficiency. This paper describes the development and high-level analysis of a set of transition pathways to a UK low carbon electricity system, explaining key features of the core pathways developed and the distinctiveness and value of the approach. The pathways use an ‘action space’ concept to explore the dynamic interactions between choices made by actors, which are influenced by the competing governance ‘framings’ or ‘logics’ that different actors pursue. The paper sets out three core transition pathways – Market Rules, Central Co-ordination and Thousand Flowers, in which market, government and civil society logics respectively dominate. It summarises the key technological and institutional changes in these pathways, and the roles of actors in bringing these about. This leads to an identification of the key risks to the realisation of each of the pathways, and of the challenges for individuals, businesses, social movements and policy-makers in taking action to bring them about and sustain them. - Highlights: ► Development of a set of transition pathways to a UK low carbon electricity system. ► Action space to explore the dynamic interactions between choices made by actors. ► Three core pathways in which market, government and civil society logics dominate. ► Key technological and institutional changes, and the roles of actors in pathways. ► Challenges for different actors in realising pathways.

Although economic, environmental, and health impacts and regulatory contexts have been compared cross-nationally, public perceptions and their antecedents have not. We conducted similar online panel surveys of national samples of UK and US residents simultaneously in September 2014 to compare public perceptions and beliefs affecting such perceptions. The US sample was more likely to associate positive impacts with development (i.e. production of clean energy, cheap energy, and advancing national energy security). The UK sample was more likely to associate negative impacts (i.e. water contamination, higher carbon emissions, and earthquakes). Multivariate analyses reveal divergence cross-nationally in the relationship between beliefs about impacts and support/opposition—especially for beliefs about energy security. People who associated shale gas development with increased energy security in the UK were over three times more likely to support development than people in the US with this same belief. We conclude with implications for policy and communication, discussing communication approaches that could be successful cross-nationally and policy foci to which the UK might need to afford more attention in its continually evolving regulatory environment.

In recent years there has being growing global interest in the generation of electricity from renewable resources. Amongst these, marine energy resource is now being considered to form a significant part of the energy mix, with plans for the implementation of several marine renewable energy schemes such as barrages and tidal stream turbines around the UK in the near future. Although marine energy presents a great potential for future electricity generation, there are major concerns over its potential impacts, particularly barrages, on the hydro-environment. Previous studies have shown that a barrage could significantly alter the hydrodynamic regime and tidal flow characteristics of an estuary, with changes to sediment transport (Kadiri et al., 2012). However, changes to nutrients have been overlooked to date. Hence, considerable uncertainty remains as to how a barrage would affect the trophic status of an estuary. This is particularly important because eutrophication can lead to algal toxin production and increased mortality of aquatic invertebrates and fish populations. Therefore, this study examines the impacts of the two different modes of operation of a barrage (i.e. ebb generation and flood-ebb generation) on the eutrophication potential of the Severn Estuary using a simplified model developed by the UK's Comprehensive Studies Task Team (CSTT). The model uses a set of equations and site-specific input data to predict equilibrium dissolved nutrient concentrations, phytoplankton biomass, light-controlled phytoplankton growth rate and primary production which are compared against CSTT set standards for assessing the eutrophic status of estuaries and coastal waters. The estuary volume and tidal flushing time under the two operating modes were estimated using a hydrodynamic model and field surveys were conducted to obtain dissolved nitrate and phosphate concentrations which served as input data. The predicted equilibrium dissolved nitrate and phosphate

Modelling farmer uptake of perennial energy crops in the UK

The UK Biomass Strategy suggests that to reach the technical potential of perennial energy crops such as short rotation coppice (SRC) willow and miscanthus by 2020 requires 350,000 hectares of land. This represents a more than 20-fold increase on the current 15,546 hectares. Previous research has identified several barriers to adoption, including concerns over security of income from contracts. In addition, farmers perceive returns from these crops to be lower than for conventional crops. This paper uses a farm-level linear programming model to investigate theoretical uptake of energy crops at different gross margins under the assumption of a profit-maximising decision maker, and in the absence of known barriers to adoption. The findings suggest that while SRC willow, at current prices, remains less competitive, returns to miscanthus should have encouraged adoption on a wider scale than at present. This highlights the importance of the barriers to adoption. Recently announced contracts for miscanthus appear to offer a significant premium to farmers in order to encourage them to grow the crops. This raises the question of whether a more cost-effective approach would be for government to provide guarantees addressing farmers concerns including security of income from the contracts. Such an approach should encourage adoption at lower gross margins. (author)

2017-07-01

Full Text Available We propose a hypothesis that fuels will continue to be critical elements of future energy systems. The reasons behind this are explored, such as the immense benefits conferred by fuels from their low cost of storage, transport, and handling, and especially in the management of the seasonal swing in heating demand for a country with a summer and winter season such as the UK. Empirical time-series data from Great Britain are used to examine the seasonal nature of the demand for liquid fuels, natural gas, and electricity, with the aid of a daily Shared Axis Energy Diagram. The logic of the continued need of fuels is examined, and the advantages and disadvantages of synthetic fuels are considered in comparison to fossil fuels.

Effects of changes in the UK energy demand and environmental legislation on atmospheric pollution by sulphur dioxide

Blakemore, F.B.; Davies, C.; Isaac, J.G.

1999-01-01

Ninety-nine percent of the sulphur dioxide generated over the period 1970 to 1994 arose from the combustion of fossil fuels in the energy sector. The annual mass emission of sulphur dioxide has fallen by 58% over this period, due to the reductions in outputs from coal and petroleum fired plants. The influence of natural-gas power generation has played an important part in this reduction. Four major pieces of environmental legislation have been enacted to control sulphur-dioxide emissions: the Control of Pollution Act 1974, and three EEC Directives are discussed. The UK emissions in 1994 were 49% below the 1980 baseline and 9% ahead of the 1998 EU target level. The protocol on the reduction of sulphur-dioxide emissions, adopted in 1985, required a cut in the total SO 2 emissions of 30% by 1993, based on 1980 levels. The UK achieved a reduction of 37% by the end of 1993. Sulphur-dioxide emissions are predicted to fall according to the six scenarios in Energy paper 65 as a reference case. The predicted decline is in line with the UNECE targets set for 2010. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam. All rights reserved.)

Co-provision in sustainable energy systems: the case of micro-generation

International Nuclear Information System (INIS)

Watson, Jim

2004-01-01

Electricity generation by individual households (known as micro-generation) is attracting an increasing amount of interest within government, industry and the research community. This paper focuses on the potential for micro-generation to contribute to a more active role for household energy consumers in the development and operation of the energy system. The paper applies the concept of energy service co-provision to aid an understanding of this more active role. It considers a number of alternative models for micro-generation investment that imply different kinds of co-provision by consumers and energy companies. The analysis focuses in particular on the economics of these models in the UK, the associated barriers to micro-generation investment, and the scope for overcoming these barriers through changes in fiscal rules. Having conducted this economic analysis, the paper concludes with a brief discussion of the wider implications of these models for consumer behaviour. In particular, it considers the impact of IT and control systems that might be employed to facilitate energy service co-provision that includes micro-generation

Willingness to pay for renewable energy: implications for UK green tariff offerings

Batley, S.L.; Fleming, P.D.; Urwin, P.

2000-01-01

Although financial support for renewable electricity sources has existed via the non-fossil fuel obligation since 1990, the UK 'green power' market is still in its infancy. This paper looks at attitudes to tariffs for 'green power' in light of the proposed phase-out of the non-fossil fuel obligation. The hypothesis tested was the consumer's willingness to pay for electricity generated from renewable energy sources and to see if this was related to income and attitude. Data for analysis were taken from replies to a questionnaire sent to an energy-aware subpopulation of Leicester which were analysed by a variety of statistical tests. Results of multiple regression analysis indicated that whether someone was willing to pay more was significantly correlated with attitude, experience (whether they had visited an environmental centre) and the purchasing power placed on GBP 5.00. This finding has implications for the methods by which support for green tariffs can be increased. Education and raising people's awareness through experience should be able to change attitudes and so increase their willingness to pay. (author)

Solid oxide fuel cell systems for residential micro-combined heat and power in the UK: Key economic drivers

Science.gov (United States)

Hawkes, Adam; Leach, Matthew

The ability of combined heat and power (CHP) to meet residential heat and power demands efficiently offers potentially significant financial and environmental advantages over centralised power generation and heat-provision through natural-gas fired boilers. A solid oxide fuel cell (SOFC) can operate at high overall efficiencies (heat and power) of 80-90%, offering an improvement over centralised generation, which is often unable to utilise waste heat. This paper applies an equivalent annual cost (EAC) minimisation model to a residential solid oxide fuel cell CHP system to determine what the driving factors are behind investment in this technology. We explore the performance of a hypothetical SOFC system—representing expectations of near to medium term technology development—under present UK market conditions. We find that households with small to average energy demands do not benefit from installation of a SOFC micro-CHP system, but larger energy demands do benefit under these conditions. However, this result is sensitive to a number of factors including stack capital cost, energy import and export prices, and plant lifetime. The results for small and average dwellings are shown to reverse under an observed change in energy import prices, an increase in electricity export price, a decrease in stack capital costs, or an improvement in stack lifetime.

NONE

2003-02-01

The Royal Commission on Environmental Pollution's Twenty Second Report 'Energy - the Changing Climate' was presented to Parliament in June 2000. The report advocates a transformation in the use of energy in the UK to counter climate change. As a contribution to global efforts to prevent excessive climate change, the Royal Commission recommends that the UK should plan to reduce carbon dioxide emissions by some 60% from current levels by about 2050. The Report explores what this will mean for industry and households and highlights how Government policies need to change. This document provides the Government's formal response to the Twenty Second Report. The response summarises the action being taken and proposed, and it relates to the Royal Commission's recommendations. Its structure is thematic, rather than being a point-by-point response. This allows the action to be described coherently, but maintains the link with the recommendations.

An initial analysis of options for a UK feed-in tariff for photovoltaic energy, from an array owner's viewpoint

International Nuclear Information System (INIS)

Plater, Steve

2009-01-01

The UK government has announced the introduction from April 2010 of a feed-in tariff (FIT) for renewable energy, and initiated a consultation on its design. This paper compares three possible variants of a UK FIT for rooftop photovoltaic (PV) arrays, on the basis of calculated income and array cost payback time, and for three locations (north, central and southern England) and various levels of household electricity consumption. This modelling is based on an FIT rate equivalent to Germany's. It concludes that an FIT which paid only for PV electricity surplus to on-site needs, and exported to the grid, would mean a simple payback time too long to make array purchase appealing. Preferable would be either export to the grid of all PV electricity for FIT payment; or a lower FIT rate for electricity used on-site, plus full FIT for any surplus exported. The latter would involve significantly lower costs in feed-in tariff payments. Finally, the effect of the UK government's illustrative FIT rate for consultation is examined for the same locations and annual consumption levels.

The impact of VAT introduction on UK residential energy demand: an investigation using the cointegration approach

International Nuclear Information System (INIS)

Fouquet, Roger

1995-01-01

Over a two-year period, which started in April 1994, the real price of energy to UK households was expected to rise by 17.5% as a result of value-added tax (VAT) introduction. The regressive nature of the tax forced the government to limit VAT on residential fuel to 8%. Using a cointegration approach, to take account of the non-stationarity fuel consumption time series, this paper estimates real energy and fuel specific price and income elasticities for the period 1974:1-1994:1. They suggest that natural gas has a positive real energy price elasticity indicating that, as real price of energy rises, households scrap inefficient heaters and invest in more efficient ones, principally natural gas. These estimates enable projections to be made of the impact of the introduction of VAT and imply a rise in natural gas consumption as a result of the additional VAT, although at the expense of other less efficient fuels.

Murphy, Gavin Bruce; Counsell, John; Allison, John; Brindley, Joseph

2013-01-01

The drive towards low carbon constructions has seen buildings increasingly utilise many different energy systems simultaneously to control the human comfort of the indoor environment; such as ventilation with heat recovery, various heating solutions and applications of renewable energy. This paper describes a dynamic modelling and simulation method (IDEAS – Inverse Dynamics based Energy Assessment and Simulation) for analysing the energy utilisation of a building and its complex servicing systems. The IDEAS case study presented in this paper is based upon small perturbation theory and can be used for the analysis of the performance of complex energy systems and also for the design of smart control systems. This paper presents a process of how any dynamic model can be calibrated against a more empirical based data model, in this case the UK Government's SAP (Standard Assessment Procedure). The research targets of this work are building simulation experts for analysing the energy use of a building and also control engineers to assist in the design of smart control systems for dwellings. The calibration process presented is transferable and has applications for simulation experts to assist in calibrating any dynamic building simulation method with an empirical based method. - Highlights: • Presentation of an energy systems analysis method for assessing the energy utilisation of buildings and their complex servicing systems. • An inverse dynamics based controller design method is detailed. • Method of how a dynamic model can be calibrated with an empirical based model

A Review of Past Reactor Progress in the UK, April 1975

Smith, R.D.

1975-01-01

The fast reactor project in the UK is continuing at approximately the same scale of effort as last year, with great attention being paid to overcoming the difficulties being met in raising PFR to full power. Organisational arrangements for nuclear power in the UK during the year have been dominated by two interlinked issues, firstly the choice of thermal reactor system for the next stage of the British nuclear power programme, and secondly the consolidation of the British nuclear design and construction industry. On the former, widespread discussion on the merits of alternative thermal systems culminated in the announcement by the Secretary of State for Energy on 10 July 1974 that the British electricity boards would adopt the SGHWR for their next nuclear power station orders. The initial ordering programme was set at 4000 KW(E) over the next four years, with the prospect of extending the programme in the later 1970s given satisfactory initial experience of construction. Consent has now been given by the Department of Energy to the CEGB for an SGHWR station at Sizewell in Suffolk (adjacent to an existing Magnox station) and to the SSEB for one at Torness Point in East Lothian

2009-07-01

Full Text Available Abstract Background This work explores the potential contribution of bioenergy technologies to 60% and 80% carbon reductions in the UK energy system by 2050, by outlining the potential for accelerated technological development of bioenergy chains. The investigation was based on insights from MARKAL modelling, detailed literature reviews and expert consultations. Due to the number and complexity of bioenergy pathways and technologies in the model, three chains and two underpinning technologies were selected for detailed investigation: (1 lignocellulosic hydrolysis for the production of bioethanol, (2 gasification technologies for heat and power, (3 fast pyrolysis of biomass for bio-oil production, (4 biotechnological advances for second generation bioenergy crops, and (5 the development of agro-machinery for growing and harvesting bioenergy crops. Detailed literature searches and expert consultations (looking inter alia at research and development needs and economic projections led to the development of an 'accelerated' dataset of modelling parameters for each of the selected bioenergy pathways, which were included in five different scenario runs with UK-MARKAL (MED. The results of the 'accelerated runs' were compared with a low-carbon (LC-Core scenario, which assesses the cheapest way to decarbonise the energy sector. Results Bioenergy was deployed in larger quantities in the bioenergy accelerated technological development scenario compared with the LC-Core scenario. In the electricity sector, solid biomass was highly utilised for energy crop gasification, displacing some deployment of wind power, and nuclear and marine to a lesser extent. Solid biomass was also deployed for heat in the residential sector from 2040 in much higher quantities in the bioenergy accelerated technological development scenario compared with LC-Core. Although lignocellulosic ethanol increased, overall ethanol decreased in the transport sector in the bioenergy

Financing nuclear power in the U.K

1979-01-01

In the United Kingdom the Central Electricity Generating Board (CEGB) are responsible for bulk supplies of electricity to the 12 Area Boards responsible for retailing in England and Wales. As such, the Board are responsible for over 90% of total generation in the UK and are therefore the body principally concerned with the financing of nuclear power growth. The author first looks at the problem of financing nuclear power from the point of view of the CEGB. Thereafter the situation in the UK is dealt with more generally and in that section reference is also made to the total call on the UK's resources involved in financing energy growth in general and nuclear power in particular.

Out-of-home meals have been characterised as delivering excessively large portions that can lead to high energy intake. Regular consumption is linked to weight gain and diet related diseases. Consumption of out-of-home meals is associated with socio-demographic and anthropometric factors, but the relationship between habitual consumption of such meals and mean daily energy intake has not been studied in both adults and children in the UK. We analysed adult and child data from waves 1-4 of the UK National Diet and Nutrition Survey using generalized linear modelling. We investigated whether individuals who report a higher habitual consumption of meals out in a restaurant or café, or takeaway meals at home had a higher mean daily energy intake, as estimated by a four-day food diary, whilst adjusting for key socio-demographic and anthropometric variables. Adults who ate meals out at least weekly had a higher mean daily energy intake consuming 75-104 kcal more per day than those who ate these meals rarely. The equivalent figures for takeaway meals at home were 63-87 kcal. There was no association between energy intake and frequency of consumption of meals out in children. Children who ate takeaway meals at home at least weekly consumed 55-168 kcal more per day than those who ate these meals rarely. Additionally, in children, there was an interaction with socio-economic position, where greater frequency of consumption of takeaway meals was associated with higher mean daily energy intake in those from less affluent households than those from more affluent households. Higher habitual consumption of out-of-home meals is associated with greater mean daily energy intake in the UK. More frequent takeaway meal consumption in adults and children is associated with greater daily energy intake and this effect is greater in children from less affluent households.

An Optimisation Study on Integrating and Incentivising Thermal Energy Storage (TES in a Dwelling Energy System

Directory of Open Access Journals (Sweden)

2018-04-01

Full Text Available In spite of the benefits from thermal energy storage (TES integration in dwellings, the penetration rate in Europe is 5%. Effective fiscal policies are necessary to accelerate deployment. However, there is currently no direct support for TES in buildings compared to support for electricity storage. This could be due to lack of evidence to support incentivisation. In this study, a novel systematic framework is developed to provide a case in support of TES incentivisation. The model determines the costs, CO2 emissions, dispatch strategy and sizes of technologies, and TES for a domestic user under policy neutral and policy intensive scenarios. The model is applied to different building types in the UK. The model is applied to a case study for a detached dwelling in the UK (floor area of 122 m2, where heat demand is satisfied by a boiler and electricity imported from the grid. Results show that under a policy neutral scenario, integrating a micro-Combined Heat and Power (CHP reduces the primary energy demand by 11%, CO2 emissions by 21%, but with a 16 year payback. Additional benefits from TES integration can pay for the investment within the first 9 years, reducing to 3.5–6 years when the CO2 levy is accounted for. Under a policy intensive scenario (for example considering the Feed in Tariff (FIT, primary energy demand and CO2 emissions reduce by 17 and 33% respectively with a 5 year payback. In this case, the additional benefits for TES integration can pay for the investment in TES within the first 2 years. The framework developed is a useful tool is determining the role TES in decarbonising domestic energy systems.

Energy in transition

A plentiful, benign supply of energy is essential for a high standard of living. The current temporary oil surplus will soon be exhausted. Because of air pollution and the possible climatic changes which may be caused by increasing carbon dioxide in the atmosphere, fossil fuel combustion should be reduced. Oil and coal extraction also damage the environment. Fission nuclear energy has problems, fusion research lacks research funds. Renewable energy systems have not shown much promise for large-scale use. New energy systems must be developed and implemented. A system with fusion as the primary source and hydrogen (from the electrolysis of water) as the storage and distribution medium, is suggested as a potential system. (U.K.)

2011-01-01

Life cycle assessment (LCA) of slow pyrolysis biochar systems (PBS) in the UK for small, medium and large scale process chains and ten feedstocks was performed, assessing carbon abatement and electricity production. Pyrolysis biochar systems appear to offer greater carbon abatement than other bioenergy systems. Carbon abatement of 0.7-1.3 t CO 2 equivalent per oven dry tonne of feedstock processed was found. In terms of delivered energy, medium to large scale PBS abates 1.4-1.9 t CO 2 e/MWh, which compares to average carbon emissions of 0.05-0.30 t CO 2 e/MWh for other bioenergy systems. The largest contribution to PBS carbon abatement is from the feedstock carbon stabilised in biochar (40-50%), followed by the less certain indirect effects of biochar in the soil (25-40%)-mainly due to increase in soil organic carbon levels. Change in soil organic carbon levels was found to be a key sensitivity. Electricity production off-setting emissions from fossil fuels accounted for 10-25% of carbon abatement. The LCA suggests that provided 43% of the carbon in the biochar remains stable, PBS will out-perform direct combustion of biomass at 33% efficiency in terms of carbon abatement, even if there is no beneficial effect upon soil organic carbon levels from biochar application. - Research highlights: → Biochar systems offer greater carbon abatement than combustion or gasification. → Carbon abatement of 0.7-1.4t CO 2 e/dry tonne of feedstock processed was found. → Change in soil organic carbon stocks induced by biochar is the key sensitivity. → Biochar systems produce less electricity then combustion or gasification.

The urban-rural planning inspector system of China is hierarchical supervision over local governments from the Central Government in respect of town and country development. The comparative analysis on planning inspection system of the UK may provide experience in seeking solutions to the problems occurring in the system of China. The planning inspector system of China can be improved in six aspects such as establishing the legal status, setting up the planning inspection agency, completing the personnel management system, enhancing the legal binding force, building the internal and external supervision channel, supplementing the relieve function, and establishing the coordination mechanism of various internal supervisions.

Although penetration of wind generation may displace a significant amount of energy produced by large conventional plant, there are issues associated with the extent to which wind generation will be able to replace the capacity and flexibility of conventional generating plant. This is important since wind power is variable, so it will be necessary to retain a significant proportion of conventional plant to ensure security of supply especially under conditions of high demand and low wind. Hence, the capacity value of wind generation will be limited as it will not be possible to displace conventional generation capacity on a ''megawatt for megawatt'' basis. Wind power is variable and not easy to predict, hence various forms of additional reserves will be needed to maintain the balance between supply and demand at all times. Additionally, if the majority of wind generation plant is located in Scotland and the North of England, reinforcement of the transmission network will be needed to accommodate the increases in the north-south flow of electricity. In this paper an assessment of the costs and benefits of wind generation on the UK electricity system is carried out, assuming different levels of wind power capacity. Overall, it is concluded that the system will be able to accommodate significant increases in wind power generation with relatively small increases in overall costs of supply, about 5% of the current domestic electricity price in case of 20% energy produced by wind power.

Knowles, Michael

1998-01-01

In order to meet the United Kingdom's targets for carbon dioxide emissions reduction, agreed at the Kyoto Summit, the UK Government is promoting the use of combined heat and power (CHP) plants. Such schemes need to offer over 70% efficiency, have on-site or nearby heat uses, and allow flexibility for the export of electricity where this is appropriate. Electricity trading arrangements will need to be re-organised in line with similar commodities, in order to facilitate and promote the growth of CHP and renewable energy schemes. Financial incentives and regulation of electricity prices will also contribute to the promotion of CHP schemes, ultimately leading to reduced CO 2 pollution as a result of the growth in the UK's CHP capacity.

Nuclear prospects in the UK

Hawley, Robert

1993-01-01

During the late 1980s and early 1990s the UK government decided to privatise the UK electricity supply industry. In order to introduce competition into the generation side of the business it was decided that the large generating boards - the Central Electricity Generating Board (CEGB) and in Scotland, the South of Scotland Electricity Board and North of Scotland Hydro Board, - should be split up into smaller companies. In England and Wales two companies were proposed. The larger company National Power would include the nuclear generating business in England and Wales, the smaller company, Power Gen would use fossil generation only. Scotland was also to have two companies, Scottish Power - including Scotland's nuclear stations - and Scottish Hydro. But these were troubled times for the UK nuclear industry. A lot of misinformation was being issued by its opponents, in particular about decommissioning and fuel reprocessing costs. Looking back I can see there were reasons for that. Both National Power and Scottish Power wanted to be absolutely certain that they got the best possible deal and that every imaginable, and unimaginable, cost that may ever arise would be taken care of. This attitude resulted in the estimate of huge liabilities and 'unprecedented guarantees' that the then Secretary of State for Energy in the UK, could not accept

The impact of uncertainties on the UK's medium-term climate change targets

International Nuclear Information System (INIS)

Watson, Jim; Gross, Rob; Ketsopoulou, Ioanna; Winskel, Mark

2015-01-01

The UK is committed to ambitious medium- and long-term climate change targets, including a commitment to an 80% reduction in emissions from 1990 levels by 2050. Whilst emissions have fallen significantly since 1990, further reductions will be increasingly difficult to achieve. The government has agreed carbon budgets to the late 2020s that are consistent with the long-term 80% target. However, increasing energy prices since the mid-2000s and the 2008 financial crisis have led to cracks in the political consensus in support of these budgets and targets. This paper carries out an assessment of the feasibility of the UK's agreed low carbon pathway over the medium term, with a particular focus on the fourth carbon budget (2023–27). It analyses the uncertainties associated with the specific changes that may be necessary to comply with this carbon budget – including measures to decarbonise electricity, heat and transport. This analysis focuses on ‘instrumental’ uncertainties associated with specific areas of the energy system (e.g. the decarbonisation of heat in households) and ‘systemic’ uncertainties that tend to have more pervasive implications for the energy system as a whole (e.g. uncertainties associated with public attitudes). A framework is developed that sets out and analyses the key uncertainties under those two broad categories, in terms of their complexity and their potential impact on the fourth carbon budget. Through the application of this framework the paper also considers strategies to mitigate or manage these uncertainties, and which actors could help develop and implement these strategies. - Highlights: • Many uncertainties remain about the achievability of UK emissions reduction targets. • This paper assesses uncertainties that could have the greatest impact on compliance with the 4th carbon budget (2023–2027). • The paper also suggests strategies that could help to manage or mitigate these uncertainties.

Regional distribution of photovoltaic deployment in the UK and its determinants: A spatial econometric approach

2015-01-01

Photovoltaic (PV) panels offer significant potential for contributing to the UK's energy policy goals relating to decarbonisation of the energy system, security of supply and affordability. The substantive drop in the cost of panels since 2007, coupled with the introduction of the Feed-in Tariff (FiT) Scheme in 2010, has resulted in a rapid increase in installation of PV panels in the UK, from 26.5MWp in 2009 to over 5GW by the end of 2014. Yet there has been no comprehensive analysis of the determinants of PV deployment in the UK. This paper addresses this gap by employing spatial econometrics methods to a recently available data set at a fine geographical detail. Following a traditional regression analysis, a general to specific approach has been adopted where spatial variations in the relationships have been examined utilising the spatial Durbin model using the cross-sectional data relating to the UK NUTS level 3 data. Empirical results indicate that demand for electricity, population density, pollution levels, education level of households and housing types are among the factors that affect PV uptake in a region. Moreover Lagrange Multiplier test results indicate that the spatial Durbin model may be properly applied to describe the PV uptake relationship in the UK as there are significant regional spillover effects. - Highlights: • Spatial econometrics models applied to UK PV installation for the first time • Significant regional spillover effects are apparent. • Smaller households in highly polluted, less dense areas are the early adopters. • Strong substitution effect as high electricity spending induces PV installations. • Solar irradiation data are found to be significant.

This paper investigates the potential advantages and disadvantages of green power products, as opposed to the traditional fossil fuel levy (which was the UK's chosen tax regime), as a means of developing renewable energy in the UK. Willingness to pay for electricity generated from renewables is investigated. Results indicate that willingness to pay varies with social status and income. However results demonstrate that there is a significant minority in full support of some sort of fiscal initiative. Electricity generated from renewables is a concept supported by the majority. However, given the stated willingness to pay it is unlikely that any new renewable capacity will result from green tariff schemes in the near term. It is concluded that the green citizen must continue to co-exist with the green power purchaser if the UK is to make any significant improvement in the contribution of renewable energy to electricity demand.

Achieving growth within the UK's Domestic Energy Efficiency Retrofitting Services sector, practitioner experiences and strategies moving forward

International Nuclear Information System (INIS)

Gooding, Luke; Gul, Mehreen S.

2017-01-01

The adoption of the UK Green Deal policy provided an unprecedented change within the policy arena of domestic retrofit. Government financial support present within previous policy regimes was reduced and private industry was enlisted to provide finance, delivery mechanisms and management schemes for national domestic low carbon retrofit. Consequently, the Energy Efficiency Retrofit Services (EERS) sector needed to grow capacity and deliver retrofit at a larger scale. This research focuses on assessing the present EERS sector industry and its strategy to increase retrofit activity. This paper provides findings from on the ground interviews with UK EERS sector practitioners with relation to their experience of working with the Green Deal, and also their suggested strategies progressing forward now the Green Deal is no longer operational. Key findings suggest that UK EERS sector practitioners were unprepared to professionally deal with the expectation of the Green Deal, in terms of business administration and also dealing with the policy itself. Moving forward an emphasis is suggested which focused on training, to enable an increase in EERS sector capabilities, and to also enable an improvement of the quality and variety of work completed. Additionally, findings detail the requirement for enhanced communication between clients and policy administrators, to increase clarity in policy implementation and stakeholder expectation. - Highlights: • Assessment of Green Deal from supply chain perspective. • Highlighting of strategies utilised by retrofit practitioners to implement policy. • Indication of possible routes forward for domestic retrofit policy.

Incorporating technology buying behaviour into UK-based long term domestic stock energy models to provide improved policy analysis

International Nuclear Information System (INIS)

Lee, Timothy; Yao, Runming

2013-01-01

The UK has a target for an 80% reduction in CO 2 emissions by 2050 from a 1990 base. Domestic energy use accounts for around 30% of total emissions. This paper presents a comprehensive review of existing models and modelling techniques and indicates how they might be improved by considering individual buying behaviour. Macro (top-down) and micro (bottom-up) models have been reviewed and analysed. It is found that bottom-up models can project technology diffusion due to their higher resolution. The weakness of existing bottom-up models at capturing individual green technology buying behaviour has been identified. Consequently, Markov chains, neural networks and agent-based modelling are proposed as possible methods to incorporate buying behaviour within a domestic energy forecast model. Among the three methods, agent-based models are found to be the most promising, although a successful agent approach requires large amounts of input data. A prototype agent-based model has been developed and tested, which demonstrates the feasibility of an agent approach. This model shows that an agent-based approach is promising as a means to predict the effectiveness of various policy measures. - Highlights: ► Long term energy models are reviewed with a focus on UK domestic stock models. ► Existing models are found weak in modelling green technology buying behaviour. ► Agent models, Markov chains and neural networks are considered as solutions. ► Agent-based modelling (ABM) is found to be the most promising approach. ► A prototype ABM is developed and testing indicates a lot of potential.

The role of built environment energy efficiency in a sustainable UK energy economy

Clarke, Joseph A.; Johnstone, Cameron M.; Kelly, Nicolas J.; Strachan, Paul A.; Tuohy, Paul

2008-01-01

Energy efficiency in the built environment can make significant contributions to a sustainable energy economy. In order to achieve this, greater public awareness of the importance of energy efficiency is required. In the short term, new efficient domestic appliances, building technologies, legislation quantifying building plant performance, and improved building regulations to include installed plant will be required. Continuing these improvements in the longer term is likely to see the adoption of small-scale renewable technologies embedded in the building fabric. Internet-based energy services could deliver low-cost building energy management and control to the mass market enabling plant to be operated and maintained at optimum performance levels and energy savings quantified. There are many technology options for improved energy performance of the building fabric and energy systems and it is not yet clear which will prove to be the most economic. Therefore, flexibility is needed in legislation and energy-efficiency initiatives

Investment barriers and incentives for marine renewable energy in the UK: An analysis of investor preferences

International Nuclear Information System (INIS)

Leete, Simeon; Xu, Jingjing; Wheeler, David

2013-01-01

Deployment of marine renewable energy (MRE) in the UK is desirable in order to address climate change, meet mandatory EU renewable energy targets and provide significant economic development opportunities, including new export markets. Public funding constraints in the UK mean that substantial investment is required from the private sector to commercialize the industry. By focussing on investor attitudes and behaviours towards wave and tidal technologies, this paper reveals significant observations from the investment community with serious implications for the future of the MRE industry. Through a series of in-depth interviews with individuals from the investment community, device developers and industry support, the research seeks to identify common barriers and incentives to investment. The paper demonstrates that although investors' attitudes are generally aligned, they do appear to have changed over time. Of the participants that had previously invested in early stage MRE device development, none were likely to do so again. It is concluded that this is a function of investors' greater understanding of the scale, and unpredictability of the costs, and the length of time required to develop these technologies. This presents a significant policy challenge for all actors interested in the commercialization of wave and tidal technologies. - Highlights: • Performed a series of in-depth interviews with senior finance and industry actors. • Examined investor attitudes and policy preferences that may encourage investment. • VC investors are currently disinclined to invest in early stage device development. • Policy instability, level of capital and revenue support are key investment barriers. • Commercialization requires strategic government and industrial partner investment

Energy infrastructure: hydrogen energy system

Energy Technology Data Exchange (ETDEWEB)

Veziroglu, T N

1979-02-01

In a hydrogen system, hydrogen is not a primary source of energy, but an intermediary, an energy carrier between the primary energy sources and the user. The new unconventional energy sources, such as nuclear breeder reactors, fusion reactors, direct solar radiation, wind energy, ocean thermal energy, and geothermal energy have their shortcomings. These shortcomings of the new sources point out to the need for an intermediary energy system to form the link between the primary energy sources and the user. In such a system, the intermediary energy form must be transportable and storable; economical to produce; and if possible renewable and pollution-free. The above prerequisites are best met by hydrogen. Hydrogen is plentiful in the form of water. It is the cheapest synthetic fuel to manufacture per unit of energy stored in it. It is the least polluting of all of the fuels, and is the lightest and recyclable. In the proposed system, hydrogen would be produced in large plants located away from the consumption centers at the sites where primary new energy sources and water are available. Hydrogen would then be transported to energy consumption centers where it would be used in every application where fossil fuels are being used today. Once such a system is established, it will never be necessary to change to any other energy system.

A UK perspective on recycling

International Nuclear Information System (INIS)

Williams, T.

1991-01-01

The United Kingdom, through the recycling of depleted uranium from Magnox reactors into Advanced Gas-cooled Reactor (AGR) fuel, has already recycled significant quantities of reprocessed material in reactors owned by Nuclear Electric plc and Scottish Nuclear Limited. This AGR fuel has been satisfactorily irradiated and discharged over a decade or more, and will be reprocessed in the new Thermal Oxide Reprocessing Plant (THORP), currently under construction in the UK. British Nuclear Fuels plc (BNFL) and the UK Atomic Energy Authority (UKAEA) have also been exploiting the potential of plutonium recycled in mixed oxide (MOX) fuel, which they have been making since 1963. All of the UK nuclear companies are committed to further recycling of Magnox depleted uranium during the 1990s, and it is anticipated that oxide recycling will also become firmly established during the next decade. British Nuclear Fuels and Urenco Ltd, as the providers of fuel cycle services, are developing an infrastructure to close the fuel cycle for oxide nuclear fuel, using both the uranium and plutonium arising from reprocessing.

The UK electricity market and the wind industry - a perspective of 1998 proposals

International Nuclear Information System (INIS)

Batley, S.L.; Twidell, J.W.; Gibbons, C.

1997-01-01

After April 1st 1998, the Public Electricity Supplier monopoly ( in England, Wales and Scotland) over their local franchise market will cease and all customers, regardless of size, will be able to choose their supplier. These changes will have a major impact on the UK wind energy industry. An increased number of Second Tier Suppliers will compete with existing market players for electricity purchase from generators and sale of electricity to consumers. Market changes should improve possibilities for wind generators to obtain a Second Tier Supplier licence and serve the domestic, small demand, market. There may also be market opportunities to sell to specialist 'green' suppliers. The post 1998 changes are of importance to the European Union 'Guarantee of Result' project, which aims to promote small scale wind systems through guaranteed quality and performance of systems. For the Guarantee of Results to be utilised in the UK, all markets for the generated electricity from a wind system must be considered and evaluated. (Author)

Highlights: • 66 elements, including “critical strategic elements” were determined in UK EfW APC residues. • Metal pollutants (Zn, Pb, As, Cd, Cu, Mo, Sb, Sn, Se, Ag and In) are enriched in APC residues. • Metal pollutants were widely associated with fine deposits of highly soluble CaCl{sub x}OH{sub 2−x}. • Specific metal (Zn, Pb, Cu)-bearing minerals were also detected in APC residues. - Abstract: Air pollution control (APC) residues from energy-from-waste (EfW) are alkaline (corrosive) and contain high concentrations of metals, such as zinc and lead, and soluble salts, such as chlorides and sulphates. The EPA 3050B-extractable concentrations of 66 elements, including critical elements of strategic importance for advanced electronics and energy technologies, were determined in eight APC residues from six UK EfW facilities. The concentrations of Ag (6–15 mg/kg) and In (1–13 mg/kg), as well as potential pollutants, especially Zn (0.26–0.73 wt.%), Pb (0.05–0.2 wt.%), As, Cd, Cu, Mo, Sb, Sn and Se were found to be enriched in all APC residues compared to average crustal abundances. Results from a combination of scanning electron microscopy with energy dispersive X-ray spectroscopy and also powder X-ray diffraction, thermal analysis and Fourier transform infrared spectroscopy give an exceptionally full understanding of the mineralogy of these residues, which is discussed in the context of other results in the literature. The present work has shown that the bulk of the crystalline phases present in the investigated APC residues include Ca-based phases, such as CaCl{sub x}OH{sub 2−x}, CaCO{sub 3}, Ca(OH){sub 2}, CaSO{sub 4}, and CaO, as well as soluble salts, such as NaCl and KCl. Poorly-crystalline aragonite was identified by FTIR. Sulphur appears to have complex redox speciation, presenting as both anhydrite and hannebachite in some UK EfW APC residues. Hazardous elements (Zn and Pb) were widely associated with soluble Ca- and Cl-bearing phases

Demand reduction in the UK - with a focus on the non-domestic sector

International Nuclear Information System (INIS)

Toke, D.

2007-01-01

A demand reduction strategy is considered in the context of the UK and in the light of the UK Government's 2006 Energy Review. This paper discusses how a mechanism - a Demand Reduction Obligation (DRO) - can be established to achieve radical energy demand reduction targets in electricity and gas use in the industrial, commercial and public administration sectors. A DRO would require energy suppliers to invest in energy-saving measures so as to reduce energy demand in these sectors. The investment for this activity would be funded by energy suppliers who would increase prices in order to cover the cost of achieving the carbon reductions. Public opinion surveys suggest that a large proportion of the public would prefer to support demand reduction measures compared to other energy options. It may be practical to deliver carbon emission reductions equivalent to around 30% of emissions from the UK electricity sector over a 15-year period through a broad-based demand reduction strategy. Demand reduction is considered in the context of an assessment of costs and resources available from other low carbon options including renewable energy and nuclear power. [Author

Strategies for enhancing environmental management are a key focus for the government in the UK. Using a manufacturing company from the construction sector as a case study, this paper evaluates selected interventionist techniques, including environmental teams, awareness raising and staff training to improve environmental performance. The study employed a range of methods including questionnaire surveys and audits of energy consumption and generation of waste to examine the outcomes of the selected techniques. The results suggest that initially environmental management was not a focus for either the employees or the company. However, as a result of employing the techniques, the company was able to reduce energy consumption, increase recycling rates and achieve costs savings in excess of £132,000.

The economic benefit of short-term forecasting for wind energy in the UK electricity market

Barthelmie, R.J.; Murray, F.; Pryor, S.C.

2008-01-01

In the UK market, the total price of renewable electricity is made up of the Renewables Obligation Certificate and the price achieved for the electricity. Accurate forecasting improves the price if electricity is traded via the power exchange. In order to understand the size of wind farm for which short-term forecasting becomes economically viable, we develop a model for wind energy. Simulations were carried out for 2003 electricity prices for different forecast accuracies and strategies. The results indicate that it is possible to increase the price obtained by around pound 5/MWh which is about 14% of the electricity price in 2003 and about 6% of the total price. We show that the economic benefit of using short-term forecasting is also dependant on the accuracy and cost of purchasing the forecast. As the amount of wind energy requiring integration into the grid increases, short-term forecasting becomes more important to both wind farm owners and the transmission/distribution operators.

Promoting nuclear energy: market price or regulated tariffs? - 5042

International Nuclear Information System (INIS)

Percebois, J.

Because of its negative effects, the scheme for aiding renewable energies presently in force in Europe is likely to penalise investments in nuclear energy. The F.I.T. system is a costly mechanism and a source of perverse effects as a switching of the merit order curve on the spot electricity market (with sometimes negative prices). Restoring an equity and 'equal opportunity' for nuclear energy in Europe needs to implement a 'Contract for Differences' scheme for nuclear energy, like the model now gaining favour in the U.K. The contract for differences signed between EDF and the UK government means that if the wholesale price that EDF secures for Hinckley's power falls below the index-linked preset value, the difference will be covered by payments from the UK government. It appears that nuclear power has weakened in Europe by the system of guaranteed purchase prices for renewable energies. Moreover this system is costly. New fairer rules must be implemented in the market. Either the market is left on its own to send the signals to all investors (including renewable energies), or a minimum of regulation is introduced in order to limit the costly surges of under and over capacity. But in the latter case it is necessary to treat all the energy sources in an equal way and guarantee the nuclear industry that it will also recover its fixed costs over the long term)

2016-10-21

Since the 'Francis Report', UK regulation focusing on patient safety has significantly changed. Healthcare workers are increasingly involved in NHS England patient safety initiatives aimed at improving reporting and learning from patient safety incidents (PSIs). Unfortunately, dentistry remains 'isolated' from these main events and continues to have a poor record for reporting and learning from PSIs and other events, thus limiting improvement of patient safety in dentistry. The reasons for this situation are complex.This paper provides a review of the complexities of the existing systems and procedures in relation to patient safety in dentistry. It highlights the conflicting advice which is available and which further complicates an overly burdensome process. Recommendations are made to address these problems with systems and procedures supporting patient safety development in dentistry.

2011-01-01

The total annual CO 2 emissions associated with the energy consumption of the major retail food outlets in the UK amount to around 4.0 MtCO 2 . The energy consumption and emissions from supermarkets varies widely and can depend on many factors such as the type and size of the store, business and merchandising practices and refrigeration and environmental control systems used. This paper provides energy consumption data of a sample of 2570 retail food stores from a number of major retail food chains in the UK. The sample covers all major store categories from convenience stores to hypermarkets and includes approximately 30% of the total number of stores in the UK having a net sales area more than 280 m 2 . The data show a wide variability of energy intensity even within stores of the same retail chain. A power law can be used to describe the variation of the average electrical energy intensity of the stores in the sample with sales area. If the electrical intensity of the stores above the average is reduced to the average by energy conservation measures, annual energy savings of the order of 10% or 840 GWh can be achieved representing 355,000 tonnes annual reduction in CO 2 emissions. The paper also discusses the major energy consuming processes in retail food stores and identifies opportunities for energy savings. - Research highlights: → Energy consumption by supermarkets in the UK is significant and a wide variability exists between stores of similar size. → Energy conservation measures to reduce energy consumption of individual stores to the average can produce a0% energy savings. → Significant opportunities for energy savings exist from the integration of HVAC and refrigeration equipment.

Why and how to subsidise energy R+D: Lessons from the collapse and recovery of electricity innovation in the UK

International Nuclear Information System (INIS)

Jamasb, Tooraj; Pollitt, Michael G.

2015-01-01

The UK electricity sector liberalisation was a pioneer in the worldwide reform trend and its reform model and outcomes have been the subject of many studies. However, lesser known are the effects of privatisation, market based reforms, and incentive regulation of networks on research and development as well as patenting activities in the sector. This paper updates our previous studies of this subject and discusses the recent developments in the innovative activities in the UK electricity sector. We find that, in recent years, the initial absence of support policies and the subsequent decline in innovation efforts in the aftermath of the reform has resulted in efforts towards forming an energy technology and innovation policy. Although we already observe some positive outcomes from these efforts, we discuss whether the balance of the innovation efforts are calibrated appropriately and whether the institutional framework can be further improved to promote long term progress. -- Highlights: •We discuss the impact of electricity market reforms on innovation in the UK. •We show that both R+D expenditure and innovation output have recovered sharply. •We discuss some of the new institutional arrangements which have support this. •We conclude that new ways of supporting R+D are needed

Full Text Available SHOT (Serious Hazards of Transfusion scheme is the UK’s National confidential haemovigilance system, and was set up in 1996. It is an independent, confidential, professionally led haemovigilance scheme. Initially the reporting was voluntary but now required by several professional bodies. SHOT publishes annual reports with recommendations and circulates to all relevant organizations including the 4 UK Blood services, Departments of Health in England, Wales, Scotland and Northern Ireland, all relevant professional bodies and reporting hospitals. Over the 17 years of reporting, the evidence gathered has prompted changes in transfusion practice from the selection and management of donors to changes in hospital practice, better education and training. Acute transfusion reactions and transfusion-associated circulatory overload carry the highest risk for morbidity and death. Greatest risk to patients remain errors in the process at the point of blood sampling, in the laboratory and at bedside administration. SHOT’s objectives are to use findings to improve standards of hospital transfusion practice, to educate users on transfusion hazards and prevention, to aid production of clinical guidelines in blood transfusion and to inform national policy on transfusion safety. MHRA is the UK competent authority to which serious adverse reactions and events have to be reported annually. Overall the most common adverse incidents are caused by errors, resulting in the transfusion of an incorrect component or one that does not meet the specific requirements of the patient (e.g. not irradiated or not appropriately antigen matched. TACO (transfusion associated circulatory overload accounts for most deaths and major morbidity reported to SHOT but is overall underreported. Transfusions are not always given appropriately. This may be due to wrong haemoglobin results, failure to assess patients appropriately, or avoidable use of emergency O RhD negative units because

To estimate the annual cost of treating pressure ulcers in the UK. Costs were derived from a bottom-up methodology, based on the daily resources required to deliver protocols of care reflecting good clinical practice. Health and social care system in the UK. Patients developing a pressure ulcer. A bottom-up costing approach is used to estimate treatment cost per episode of care and per patient for ulcers of different grades and level of complications. Also, total treatment cost to the health and social care system in the UK. The cost of treating a pressure ulcer varies from pound 1,064 (Grade 1) to pound 10,551 (Grade 4). Costs increase with ulcer grade because the time to heal is longer and because the incidence of complications is higher in more severe cases. The total cost in the UK is pound 1.4- pound 2.1 billion annually (4% of total NHS expenditure). Most of this cost is nurse time. Pressure ulcers represent a very significant cost burden in the UK. Without concerted effort this cost is likely to increase in the future as the population ages. To the extent that pressure ulcers are avoidable, pressure damage may be indicative of clinical negligence and there is evidence that litigation could soon become a significant threat to healthcare providers in the UK, as it is in the USA.

Up to the present the production, transmission and distribution of energy has been considered mostly as a fragmented problem; at best only subsystems have been considered. Today the scale of energy utilization is increasing rapidly, and correspondingly, the reliance of societies on energy. Such strong quantitative increases influence the qualitative nature of energy utilization in most of its aspects. Resources, reserves, reliability and environment are among the key words that may characterize the change in the nature of the energy utilization problem. Energy can no longer be considered an isolated technical and economical problem, rather it is embedded in the ecosphere and the society-technology complex. Restraints and boundary conditions have to be taken into account with the same degree of attention as in traditional technical problems, for example a steam turbine. This results in a strong degree of interweaving. Further, the purpose of providing energy becomes more visible, that is, to make survival possible in a civilized and highly populated world on a finite globe. Because of such interweaving and finiteness it is felt that energy should be considered as a system and therefore the term 'energy systems' is used. The production of energy is only one component of such a system; the handling of energy and the embedding of energy into the global and social complex in terms of ecology, economy, risks and resources are of similar importance. he systems approach to the energy problem needs more explanation.

Comparison of the organization and management of government funded energy efficiency research and development in the United States and the United Kingdom reveals a number of common features as well as as some important differences. The UK pattern is one of centralized agenda-setting and competition in which rival research contractors bid for small, pre-determined, ``bite-sized`` pieces of work. By contrast, the US approach involves complex negotiations between federal energy and environmental policy agencies and semi-entrepreneurial national laboratories. How do these differing research environments influence the knowledge we have of energy efficiency? How do these organizational features affect the shaping of research agendas, the definition of research problems and the management and dissemination of resulting expertise? More specifically, what consequences do these arrangements have for the conduct of needed social science studies within this conventionally technical field? In exploring these questions, the paper identifies a variety of ways in which opportunities for inter-disciplinarity are inadvertently structured by the mechanics of research management. (Author)

Public values for energy futures: Framing, indeterminacy and policy making

International Nuclear Information System (INIS)

Butler, C.; Demski, C.; Parkhill, K.; Pidgeon, N.; Spence, A.

2015-01-01

In the UK there are strong policy imperatives to transition toward low carbon energy systems but how and in what ways such transitional processes might be realised remains highly uncertain. One key area of uncertainty pertains to public attitudes and acceptability. Though there is wide-ranging research relevant to public acceptability, very little work has unpacked the multiple questions concerning how policy-makers can grapple with and mitigate related uncertainties in efforts to enact energy systems change. In this paper, public acceptability is identified as an indeterminate form of uncertainty that presents particular challenges for policy making. We build on our existing research into public values for energy system change to explore how the outcomes of the project can be applied in thinking through the uncertainties associated with public acceptability. Notably, we illustrate how the public values identified through our research bring into view alternative and quite different problem and solution framings to those currently evident within UK policy. We argue that engagement with a wide range of different framings can offer a basis for better understanding and anticipating public responses to energy system change, ultimately aiding in managing the complex set of uncertainties associated with public acceptability. - Highlights: • We argue that public acceptability represents an indeterminate form of uncertainty. • This means alternative approaches to decision-making are required. • We introduce a public value set for energy system change. • We use this as a basis for interrogating current UK policy approaches to transitions. • Incorporating public values in policy can help tackle uncertainty about acceptability.

Fuel poverty and energy efficiency obligations – A critical assessment of the supplier obligation in the UK

International Nuclear Information System (INIS)

Rosenow, Jan; Platt, Reg; Flanagan, Brooke

2013-01-01

Energy efficiency obligations (or white certificates) are increasingly used to reduce carbon emissions. While the energy efficiency obligations were originally intended as carbon reduction and not fuel poverty policies, due to recognition of the potential for regressive outcomes they often include provisions for vulnerable and low-income customers. Intuitively, reducing carbon emissions and alleviating fuel poverty seem to be two sides of the same coin. There are, however, considerable tensions between the two when addressed through energy efficiency obligations, particularly arising from the potentially regressive impacts of rising energy prices resulting from such obligations, but also the complexity of targeting fuel poor households and the implications for deliverability. Despite those tensions, the UK government decided to use energy efficiency obligations, the supplier obligation, as the main policy for reducing fuel poverty. In light of the proposals, this paper provides an analysis of the main tensions between carbon reduction and fuel poverty alleviation within energy efficiency obligations, outlines the fuel poverty provisions of the British Supplier Obligation, assesses its rules for identifying the fuel poor, and provides a critical analysis of the planned policy changes. Based on this analysis, alternative approaches to targeting fuel poverty within future supplier obligations are proposed. - Highlights: • First comprehensive analysis of energy savings obligations and fuel poverty. • Systematic comparison of targeting efficiency of fuel poverty programmes. • Critical analysis of fuel poverty provisions in British supplier obligations. • Proposal of a new approach to targeting fuel poverty within energy savings obligations

The negative impacts of the global economic downturn on funding decentralised energy in the UK

International Nuclear Information System (INIS)

Finney, Karen N.; Sharifi, Vida N.; Swithenbank, Jim

2012-01-01

Over the years, a number of governmental policies have been developed in the UK that offer grants for the installation of distributed energy technologies or financial rewards per unit of electricity/heat generated from renewable and sustainable sources. The current economic climate however has meant that budget cuts have affected almost all government departments; consequently such policies have been adversely impacted. The alterations/modifications to many schemes have resulted in either a reduction in the funding available through these, changes to the eligibility of certain technologies or scales of generation or policy cancellations. The programmes affected include the Feed-In Tariff Scheme, Renewable Heat Incentive and Low Carbon Buildings Programme, among others. The adjustments for these are detailed herein, followed by the impacts these have had on the deployment rates of decentralised energy, especially microgeneration. Since costs are often one of the most significant factors constraining deployment of these technologies, reductions in funding opportunities have made these less financially-viable. Whilst there are still applications for funding under the available schemes, there has been considerably reduced levels of requests for financial support, thus future deployment rates will most likely be negatively affected. The prospects of these technologies in this context are then considered. - Highlights: ► Costs are often a significant barrier limiting distributed energy deployment. ► The economic downturn has reduced funding for policies aiding distributed energy. ► Installing decentralised energy technologies is now less financially-viable. ► This is now starting to negatively affect uptake rates of microgeneration.

An Interdisciplinary Approach to Developing Renewable Energy Mixes at the Community Scale

Science.gov (United States)

Gormally, Alexandra M.; Whyatt, James D.; Timmis, Roger J.; Pooley, Colin G.

2013-04-01

Renewable energy has risen on the global political agenda due to concerns over climate change and energy security. The European Union (EU) currently has a target of 20% renewable energy by the year 2020 and there is increasing focus on the ways in which these targets can be achieved. Here we focus on the UK context which could be considered to be lagging behind other EU countries in terms of targets and implementation. The UK has a lower overall target of 15% renewable energy by 2020 and in 2011 reached only 3.8 % (DUKES, 2012), one of the lowest progressions compared to other EU Member States (European Commission, 2012). The reticence of the UK to reach such targets could in part be due to their dependence on their current energy mix and a highly centralised electricity grid system, which does not lend itself easily to the adoption of renewable technologies. Additionally, increasing levels of demand and the need to raise energy awareness are key concerns in terms of achieving energy security in the UK. There is also growing concern from the public about increasing fuel and energy bills. One possible solution to some of these problems could be through the adoption of small-scale distributed renewable schemes implemented at the community-scale with local ownership or involvement, for example, through energy co-operatives. The notion of the energy co-operative is well understood elsewhere in Europe but unfamiliar to many UK residents due to its centralised approach to energy provision. There are many benefits associated with engaging in distributed renewable energy systems. In addition to financial benefits, participation may raise energy awareness and can lead to positive responses towards renewable technologies. Here we briefly explore how a mix of small-scale renewables, including wind, hydro-power and solar PV, have been implemented and managed by a small island community in the Scottish Hebrides to achieve over 90% of their electricity needs from renewable

Sampling of fish, water, sediments and plants was carried out in freshwater systems in Cumbria (UK) to study the effects of Chernobyl fallout. Radionuclide concentrations were determined by gamma spectrometry and potassium and calcium ion concentrations in water were measured using atomic absorption spectrometry. The results contained in this report cover the period May 1986-March 1988. Caesium-134 and -137 were readily detected in all materials but ruthenium-103 and -106 were also found in a few samples. Trends in caesium concentrations in fish are difficult to establish because of the wide variation between fish of the same species. (author)

The system to which new energy technology and energy saving technology were introduced was constructed for case studies of urban areas including core cities and the peripheral areas, and the quantitative analysis was conducted on environmental effects, etc. In the energy supply system model, the following element technologies were all considered: cogeneration system, sewage water heat, river water heat, the photovoltaic power generation, energy storage/heat storage/cold heat storage, adsorption type refrigerator, etc. Also considered were power interchange between clusters, system power buying/power selling, heat interchange or no heat interchange, etc. As a result, it was found that when constructing the energy system which synthetically takes into account thermoelectric ratios, rates of simultaneous loads, ratios of daytime/nighttime in the energy supply and demand in the urban area, the energy saving effect multiplicatively increases, and the energy system using cogeneration and unused energy such as refuse and sewage in the urban area and river water brings an energy saving effect of 32% especially in the concentrated cluster. 83 figs., 45 tabs.

MNCs in Denmark and the UK

Multinational companies (MNCs) have more opportunities than ever to forum shop and choose between different market systems - including different industrial relations (IR) systems. When an MNC choose to engage in a certain country, it also becomes an actor in the country's labor market system. MNCs...... are often quite large companies, and hence they can become significant players, potentially affecting the existing balances between the social partners. The question is whether MNCs adapt to the host country's labor market system (host country effect) - or if they seek in various ways to change the host...... to determine the employment relations. Quite the opposite to the UK, where trade unions are weak and where collective bargaining is far less widespread. Further analyses show that MNCs originating from liberal market economies (especially the US) acts differently in the two countries; in the UK they tend...

Energy saving synergies in national energy systems

Thellufsen, Jakob Zinck; Lund, Henrik

2015-01-01

In the transition towards a 100% renewable energy system, energy savings are essential. The possibility of energy savings through conservation or efficiency increases can be identified in, for instance, the heating and electricity sectors, in industry, and in transport. Several studies point...... to various optimal levels of savings in the different sectors of the energy system. However, these studies do not investigate the idea of energy savings being system dependent. This paper argues that such system dependency is critical to understand, as it does not make sense to analyse an energy saving...... without taking into account the actual benefit of the saving in relation to the energy system. The study therefore identifies a need to understand how saving methods may interact with each other and the system in which they are conducted. By using energy system analysis to do hourly simulation...

Potential for biogas on farms in the UK (1990 update)

International Nuclear Information System (INIS)

Mosey, F.E.

1991-01-01

In a previous report, the potential for generating renewable energy as biogas on farms in the UK using a new generation of 'package plant' anaerobic digestion units was investigated. It was concluded that the digestion technology was rugged and reliable but rather expensive for general farm use. An update report is presented to determine whether anaerobic digester design concepts, increasing environmental constraints on farm waste disposal and the Electricity Industry's Non-Fossil Fuel Obligation has modified these conclusions.

The share of wind generation in the Irish and British electricity markets is set to increase by 2020 due to renewable energy (RE) targets. The United Kingdom (UK) and Ireland have set ambitious targets which require 30% and 40% of electricity demand to come from RE, mainly wind, by 2020, respectively. Ireland has sufficient indigenous onshore wind energy resources to exceed the RE target, while the UK faces uncertainty in achieving its target. A possible solution for the UK is to import RE directly from large scale onshore and offshore wind energy projects in Ireland; this possibility has recently been explored by both governments but is currently on hold. Thus, the aim of this paper is to estimate the effects of large scale wind energy in the Irish and British electricity markets in terms of wholesale system marginal prices, total generation costs and CO_2 emissions. The results indicate when the large scale Irish-based wind energy projects are connected directly to the UK there is a decrease of 0.6% and 2% in the Irish and British wholesale system marginal prices under the UK National Grid slow progression scenario, respectively. - Highlights: • Modelling the Irish and British electricity markets. • Investigating the impacts of large scale wind energy within the markets. • Results indicate a reduction in wholesale system marginal prices in both markets. • Decrease in total generation costs and CO_2 emissions in both markets.

A review of the impacts of wind farms on birds in the UK

International Nuclear Information System (INIS)

1996-01-01

The number of wind farm developments in the UK has grown rapidly in recent years. While, on a global scale, the benefits of utilising renewable energy resources are generally accepted, wind energy developments may cause local impacts to the ecological environment. In some cases, these may potentially be of significance in nature conservation terms. A major focus of the concern over such impacts has related to the extent to which wind farms affect bird life. This report reviews the present state of knowledge of this issue, drawing upon studies conducted in both the UK and elsewhere. The potential types of impact are discussed and the variables which determine the scale of such impacts are described. Recommendations are made with regard to future monitoring programmes in the UK.

System's flips in climate-related energy (CRE) systems

2014-05-01

Several modern environmental questions invite to explore the complex relationships between natural phenomena and human behaviour at a range of space and time scales. This usually involves a number of cause-effect (causal) relationships, linking actions and events. In lay terms, 'effect' can be defined as 'what happened' and 'cause', 'why something happened.' In a changing world or merely moving from one scale to another, shifts in perspective are expected, bringing some phenomena into the foreground and putting others to the background. Systems can thus flip from one set of causal structures to another in response to environmental perturbations and human innovations or behaviors, for instance, as space-time signatures are modified. The identification of these flips helps in better understanding and predicting how societies and stakeholders react to a shift in perspective. In this study, our motivation is to investigate possible consequences of the shift to a low carbon economy in terms of socio-technico systems' flips. The focus is on the regional production of Climate-Related Energy (CRE) (hydro-, wind- and solar-power). We search for information on historic shifts that may help defining the forcing conditions of abrupt changes and extreme situations. We identify and present a series of examples in which we try to distinguish the various tipping points, thresholds, breakpoints and regime shifts that are characteristic of complex systems in the CRE production domain. We expect that with these examples our comprehension of the question will be enriched, providing us the elements needed to better validate modeling attempts, to predict and manage flips of complex CRE production systems. The work presented is part of the FP7 project COMPLEX (Knowledge based climate mitigation systems for a low carbon economy; http://www.complex.ac.uk/).

This article focuses on the slow progress towards the new and strong drive for renewables promised in the UK Labour Party's manifesto, and the tentative proposal for 10% contribution of renewables by the year 2020. Onshore wind power and the planning system, key roles for offshore wind and biomass energy, growth in wave and solar power projects, increased funding for renewable energy research and development, the cost of delivering the 10% contribution of renewables, embedded power generation, and exemptions from the climate levy are discussed. The form that the stimulation of the market for renewable energy sources will take after the Non-Fossil-Fuel Obligation (NFFO) lapses, and the possibility of further NFFO orders are considered. (UK)

The relationship between gross national product and energy use is studied for a number of countries and for the United States is particular. The relationship between income inequalities and energy use is also examined. The similarity between income inequality in an economic system and temperature differences in a thermodynamic system is noted. An economic chain analysis is used to derive income inequality distributions for a less-developed country and for a very-developed country. Finally the role of expensive but domestic-origin energy is examined. (U.K.)

National renewable energy policy and local opposition in the UK: the failed development of a biomass electricity plant

International Nuclear Information System (INIS)

Upreti, B.R.; Horst, Dan van der

2004-01-01

Biomass energy developments in the UK are supported by central government but face considerable opposition from the public. The purpose of this study is to explore the causes and consequences of public opposition to biomass energy development in North Wiltshire where Ambient Energy Ltd. proposed the development of a 5 MWe wood gasification plant near the town of Cricklade. The case study was conducted through in-depth interviews, content analysis, person to person questionnaire survey, focus group discussion and participatory appraisal methods. Though biomass energy plants in general have fewer environmental impacts than plants which use fossil fuel, there could still be local impacts which give rise to concerns and local opposition to the development. The opposition could be partially explained by the fact that the general public is relatively unfamiliar with biomass energy. Public acceptance or rejection was mainly based on the public trust or mistrust. The case study demonstrates two distinctly rigid characteristics among the key stakeholders of biomass energy development. These are the 'not-in-my-back-yard' attitude from the public and the 'there-is-no-alternative' attitude of the developers. These rigid stances were widely contributing to the failure of the project to gain planning permission. The environmental justification of biomass energy at the national level is not always sufficient to convince the local residents. Winning public support to promote biomass energy requires an alternative approach of planning and action through interactive communication, public participation and collective learning among all the stakeholders

As UK inches towards Chinese reactor project, China sets sights on new world markets

Shepherd, John

2017-01-01

Early in January, as many of us in Europe were getting back into the routine of returning to work following the festive period, a new chapter in the history of nuclear energy was already starting to be written in the UK. The UK government asked the country's nuclear regulators, the Office for Nuclear Regulation (ONR) and the Environment Agency, to start a generic design assessment (GDA) of what is now known as the 'UK HPR1000 reactor' - which is set to be the first deployment of Chinese reactor technology outside China. If the UK HPR1000 is eventually built in the UK, which would be at a designated site adjacent to the country's former Bradwell nuclear power plant in Essex, on the eastern coast, the project will not only be a first for the use of Chinese nuclear technology in any other country, it will ironically make UK ties with France stronger - at a time when the UK is preparing to break away from the European Union.

Energy savings potential from energy-conserving irrigation systems

1982-11-01

This report systematically compares, within a consistent framework, the technical and economic characteristics of energy-conserving irrigation systems with those of conventional irrigation systems and to determine total energy savings. Levelized annual costs of owning and operating both energy-conserving and conventional irrigation systems have been developed and compared for all 17 states to account for the differences in energy costs and irrigation conditions in each state. Market penetration of energy-conserving systems is assessed for those systems having lower levelized annual costs than conventional systems performing the same function. Annual energy savings were computed by matching the energy savings per system with an assumed maximum market penetration of 100 percent in those markets where the levelized annual costs of energy-conserving systems are lower than the levelized annual costs of conventional systems.

Blank book on energy: priority to renewable energies and energy savings

2003-01-01

The British minister of industry and trade has presented a blank book on energy. This report has in view to curb the emission of greenhouse gases by 60 % before 2050 and to double the contribution of renewable energies by 2020 with an intermediate objective of 10 % in 2010. Today this contribution reaches 3 %. New nuclear power plants are not expected to be built. This report recalls that the United-Kingdom (UK) imports half the coal it needs and states that by 2006 UK will become a net gas importing country and by 2010 a net oil importing country. The solution promoted by the report is to rely on diverse energy sources and on diverse supplying countries. (A.C.)

Carbon and environmental footprinting of low carbon UK electricity futures to 2050

2012-01-01

Electricity generation contributes a large proportion of the total greenhouse gas emissions in the United Kingdom (UK), due to the predominant use of fossil fuel (coal and natural gas) combustion for this purpose. A range of future UK energy scenarios has been employed to determine their resulting environmental and carbon footprints. Methodologies have been established to calculate these footprints for the UK electricity supply industry on both a historic timescale and in accordance with the three selected scenarios. The latter scenarios, developed by the UK SUPERGEN Consortium on ‘Highly Distributed Power Systems’ (HDPS), were characterised as ‘Business As Usual’ (BAU), ‘Low Carbon’ (LC) and ‘Deep Green’ (DG) futures, and yielded possible electricity demands out to 2050. It was found that the environmental footprint of the current power network is 41 million (M) global hectares (gha). If future trends follow a ‘Business As Usual’ scenario, then this footprint is observed to fall to about 25 Mgha in 2050. The LC scenario implies an extensive penetration of micro-generators in the home to satisfy heat and power demands. However, these energy requirements are minimised by way of improved insulation of the building fabric and other demand reduction measures. In contrast, the DG scenario presupposes a network where centralised renewable energy technologies – mainly large-scale onshore and offshore wind turbines - have an important role in the power generation. However, both the LC and DG scenarios were found to lead to footprints of less than 4 Mgha by 2050. These latter two scenarios were found to give rise to quite similar trajectories over the period 2010–2050. They are therefore more likely to reflect an effective transition pathway in terms of meeting the 2050 UK CO 2 reduction targets associated with decarbonisation of its power network. However, this appears unlikely to be achieved by 2030–2040 as advocated by the UK Government

21st century's energy: hydrogen energy system

International Nuclear Information System (INIS)

Veziroglu, T. N.

2007-01-01

Fossil fuels (i.e., petroleum, natural gas and coal), which meet most of the world's energy demand today, are being depleted fast. Also, their combustion products are causing the global problems, such as the greenhouse effect, ozone layer depletion, acid rains and pollution, which are posing great danger for our environment and eventually for the life in our planet. Many engineers and scientists agree that the solution to these global problems would be to replace the existing fossil fuel system by the Hydrogen Energy System. Hydrogen is a very efficient and clean fuel. Its combustion will produce no greenhouse gases, no ozone layer depleting chemicals, little or no acid rain ingredients and pollution. Hydrogen, produced from renewable energy (e.g., solar) sources, would result in a permanent energy system, which we would never have to change. However, there are other energy systems proposed for the post-petroleum era, such as a synthetic fossil fuel system. In this system, synthetic gasoline and synthetic natural gas will be produced using abundant deposits of coal. In a way, this will ensure the continuation of the present fossil fuel system. The two possible energy systems for the post-fossil fuel era (i.e., the solar hydrogen energy system and the synthetic fossil fuel system) are compared with the present fossil fuel system by taking into consideration production costs, environmental damages and utilization efficiencies. The results indicate that the solar hydrogen energy system is the best energy system to ascertain a sustainable future, and it should replace the fossil fuel system before the end of the 21st Century

Working while incapable to work? Changing concepts of permitted work in the UK disability benefit system

Directory of Open Access Journals (Sweden)

Jackie Gulland

2017-11-01

Full Text Available This article focusses on the borderland between "work" and "not work" in UK disability benefit systems. People who claim disability benefits often have to prove that they are "incapable of work" in order to qualify. The idea of incapacity for work requires an understanding of the meaning of the term "work," a concept which has a common sense simplicity but which is much more difficult to define in practice. UK disability benefit systems have developed the notion of "permitted work" to allow people to do small amounts of paid work while retaining entitlement to benefit. This concept of "permitted work" has its roots in the early twentieth century when claimants were sometimes entitled to disability benefits if any work that they did was considered to be sufficiently trivial to not count as "work." Policy on this changed over time, with particular developments after the Second World War, as rehabilitation and therapy became the key focus of permitted work rules. Current developments in UK social security policy treat almost everyone as a potential worker, changing the way in which permitted work operates. This article uses archive material on appeals against refusals of benefit, policy documents and case law to consider the social meanings of these moving boundaries of permitted work. Disability benefits are not value neutral: they are measures of social control which divide benefit claimants into those who are required to participate in the labour market and those who are exempted from this requirement.

The macro-economic rebound effect and the UK economy

Barker, Terry; Ekins, Paul; Foxon, Tim

2007-01-01

This paper examines the macroeconomic rebound effect for the UK economy arising from energy efficiency policies 2000-2010 using the macroeconomic model, MDM-E3. The literature distinguishes between three types of rebound effect: direct, indirect and economy-wide. The macroeconomic rebound effect considered here is the combination of the indirect and economy-wide effects. Policies for the domestic, business, commercial and public, and transport sectors of the economy are analysed for 2000-2010. Overall, the policies lead to a saving of about 8% of the energy, which would otherwise have been used and a reduction in CO 2 emissions of 10% (or 14 mtC) by 2010. There are also favourable macroeconomic effects: lower inflation and higher growth. We find that the macroeconomic rebound effect arising from UK energy efficiency policies for the period 2000-2010 is around 11% by 2010, averaged across sectors of the economy. When this is added to the (assumed) direct rebound effect of around 15%, this gives a total rebound effect of around 26% arising from these policies. Thus, the findings of the study support the argument that energy efficiency improvements for both consumers and producers, stimulated by policy incentives, will lead to significant reductions in energy demand and hence in greenhouse gas emissions

Domestic heat pumps in the UK. User behaviour, satisfaction and performance

Consumer adoption of microgeneration technologies is part of the UK strategy to reduce carbon emissions from buildings. Domestic heat pumps are viewed as a potentially important carbon saving technology, given the ongoing decarbonisation of the electricity supply system. To address the lack of independent evaluation of heat pump performance, the Energy Saving Trust undertook the UK's first large-scale heat pump field trial, which monitored 83 systems in real installations. As part of the trial, the Open University studied the consumers' experience of using a domestic heat pump. An in-depth user survey investigated the characteristics, behaviour, and satisfactions of private householders and social housing residents using ground source and air source heat pumps for space and/or water heating, and examined the influence of user-related factors on measured heat pump system efficiency. The surveys found that most users were satisfied with the reliability, heating, hot water, warmth and comfort provided by their system. Analysis of user characteristics showed that higher system efficiencies were associated with greater user understanding of their heat pump system, and more continuous heat pump operation, although larger samples are needed for robust statistical confirmation. The analysis also found that the more efficient systems in the sample were more frequently located in the private dwellings than at the social housing sites and this difference was significant. This is explained by the interaction between differences in the systems, dwellings and users at the private and social housing sites. The implications for heat pump research, practice and policy are discussed.

Patient choice and mobility in the UK health system: internal and external markets.

Science.gov (United States)

Dusheiko, Mark

2014-01-01

The National Health Service (NHS) has been the body of the health care system in the United Kingdom (UK) for over 60 years and has sought to provide the population with a high quality service free of user charges for most services. The information age has seen the NHS rapidly transformed from a socialist, centrally planned and publicly provided system to a more market based system orientated towards patients as consumers. The forces of globalization have provided patients in the UK with greater choice in their health care provision, with NHS treatment now offered from any public or approved private provider and the possibility of treatment anywhere in the European Economic Area (EEA) or possibly further. The financial crisis, a large government deficit and austerity public spending policies have imposed a tight budget constraint on the NHS at a time of increasing demand for health care and population pressure. Hence, further rationing of care could imply that patients are incentivised to seek private treatment outside the constraints of the NHS, where the possibility of much greater choice exists in an increasingly globally competitive health care market. This chapter examines the evidence on the response of patients to the possibilities of increased choice and mobility within the internal NHS and external overseas health care markets. It also considers the relationships between patient mobility, health care provision and health policy. Patients are more mobile and willing to travel further to obtain better care outcomes and value for money, but are exposed to greater risk.

Its methodological novelty is the incorporation of a process-oriented modelling approach based on a comprehensive technology database for the industry sector in a national energy system model for the UK (UKTM), allowing quantification of the role of both decarbonisation of upstream energy vectors and of mitigation options in the industrial sub-categories. This enhanced model is then applied in a comparative policy scenario analysis that explores various target dimensions on emission mitigation, renewable energy and energy efficiency at both a national and European level. The results show that ambitious emission cuts in the industry sector of up to 77% until 2050 compared to 2010 can be achieved. Moreover, with a reduction in industrial energy demand of up to 31% between 2010 and 2050, the sector is essential for achieving the overall efficiency commitments. The industry sector also makes a moderate contribution to the expansion of renewable energies mostly through the use of biomass for low-temperature heating services. However, additional sub-targets on renewable sources and energy efficiency need to be assessed critically, as they can significantly distort the cost-efficiency of the long-term mitigation pathway.

Energy. The rude awakening

Energy Technology Data Exchange (ETDEWEB)

Bailey, R

1977-01-01

This book places UK and world energy problems in perspective. The evolution of UK energy problems are described and it is emphasized that North Sea oil will bring only temporary relief. By the end of the century the UK will probably be importing oil once more. The importance of using this period of economic grace to restructure the economy is stressed. Only in this way will the country be able to face being an oil importer again. Energy forecasts and possible policies to the end of the century are discussed, and the roles of the four main fuels (coal, gas, oil and nuclear energy) are analysed. The social and environmental problems arising from the exploitation of coal and oil reserves, and the further development of nuclear power are considered. An assessment is made of energy prospects for the next century.

Integrated Life Cycle Energy and Greenhouse Gas Analysis of Exterior Wall Systems for Residential Buildings

Directory of Open Access Journals (Sweden)

Reza Broun

2014-11-01

Full Text Available This paper investigates the breakdown of primary energy use and greenhouse gas (GHG emissions of two common types of exterior walls in the U.K.: insulated concrete form (ICF and cavity walls. A comprehensive assessment was conducted to evaluate the environmental performance of each exterior wall system over 50 years of service life in Edinburgh and Bristol. The results indicate that for both wall systems, use phase is the major contributor to the overall environmental impacts, mainly due to associated electricity consumption. For the ICF wall system in Edinburgh, 91% of GHG emissions were attributed to the use phase, with 7.8% in the pre-use and 1.2% in end-of-life phases. For the same system in Bristol, emissions were 89%, 9% and 2%, respectively. A similar trend was observed for cavity wall systems in both locations. It was concluded that in each scenario, the ICF wall system performed better when compared to the cavity wall system. The results of the sensitivity analysis clearly show that the uncertainties relevant to the change of the thickness of the wall are quite tolerable: variable up to 5%, as far as energy and greenhouse emissions are concerned.

Consultations to formulate a UK perspective for planning of the Sixth Framework Nuclear (Fission) Energy Programme. Policy issues

International Nuclear Information System (INIS)

Dutton, L.; Moscrop, R.; Smedley, C.

2000-01-01

This report provides advice to the DETR and the Health and Safety Executive on the policy aspects of the Sixth European Framework Programme (FP6) for research and technological development. This advice is based on a consultation within the UK and other Member States and covers the areas of reactor safety, decommissioning and radioactive waste management. It is concluded that there is general support for FP6 across the UK nuclear industry. The specific benefits are seen to be improvements in the competitiveness of the UK nuclear industry through research on plant life extension, improvements to the safety of existing plants and research on radioactive waste management. The broad structure of FP5 does not appear to require fundamental change for FP6 to meet the requirements of the UK, with funding staying at roughly the same level. There is agreement on the need to improve on programme organisation and management to ensure better quality of output and value for money. There is also scope for improving the organisation of UK participation to maximise the UK benefit. Further work has been undertaken under a parallel phase of this project to identify the technical requirements for FP6. (author)

The UK homeowner-retrofitter as an innovator in a socio-technical system

International Nuclear Information System (INIS)

Galvin, Ray; Sunikka-Blank, Minna

2014-01-01

Policy on domestic thermal retrofits is usually designed as a top-down enterprise, setting standards and inducing homeowners to retrofit accordingly. Its underlying assumption is that correct retrofit technology is developed by experts and comes down through supply chains to households, who apply it as designed to their properties. However, this model is challenged by the insight from socio-technical systems studies (STST) that technology and society mutually form and influence each other at every level of society. Using this conceptual framework, this study investigated whether innovations are happening among retrofitting households, and what support these have for diffusion upwards into supply chains and outwards to other households. Qualitative data was gathered through semi-structured interviews among homeowner-retrofitters plus building professionals and citizens' initiatives which support these, in Cambridge, UK. Local innovation was found in the development of new retrofit technology and novel reconfiguring of existing solutions. Much of this was triggered by clashes between standard retrofit solutions and heritage or aesthetic values, economic necessity, or building professionals' lack of knowledge or experience. The findings suggest that instead of treating homeowners as passive recipients, UK thermal retrofit policy should broaden to identify useful innovations developed by homeowners and support them where appropriate. - Highlights: • Technology and innovations for thermal retrofitting are usually seen as top-down. • A socio-technical systems approach reveals a more active role of homeowners. • Interviews show them as innovators, inventors and teachers of retrofit technique. • Policy needs to identify, assess and disseminate appropriate innovations

The UK has over several years developed a philosophy for the prevention, mitigation and extinguishment of sodium fires. The systems which were developed for PFR have been continuously revised and modified and from these considerations systems were proposed for CDFR. The latest phases of this development are described with reference to the CDFR plant. The current analytical and experimental work on fires, aerosols and sodium concrete reactions is also discussed. The UK are developing codes to analyse the effects of a sodium fire in a building and to model aerosol behaviour following a fire. Experimental work on small scale fires, aerosol behaviour, filtration devices and sodium concrete reaction is being carried out on a laboratory scale. Techniques for aerosol measurement and characterisation have also been developed and used both In the laboratory and large scale tests. Larger scale tests of sodium fire extinguishment techniques have also been performed. Currently a programme of tests (SOFA) of large scale fires in the open to investigate the chemical and physical changes in the aerosol and its dispersion in the atmosphere are just beginning. The UK studies are intended to both assist in the development of prevention and mitigation systems for design base and beyond design base accidents in any building which contains sodium (or sodium potassium alloy) and also to provide methods for assessing the risks from such accidents.

Bradley, Peter; Coke, Alexia; Leach, Matthew

2016-01-01

Whilst tariff-based approaches to load-shifting are common in the residential sector, incentive-based approaches are rare. This is so, even though providing customers incentives to shape their power consumption patterns has substantial potential. This paper presents findings from an exploratory UK pilot study that trials financial payments and detailed energy feedback to incentivise load-shifting of residential electricity consumption. An intervention study was implemented measuring actual energy use by individual households as well as conducting surveys and interviews. From the trials it was found that the approaches resulted in reductions in peak time energy use. Evidence from the study found that the incentives-based approaches were able to overcome some of the barriers to response experienced in Time-of-Use studies, though less good on others. Interestingly, the height of the barriers varied by the electricity-using practice and the incentivising approach applied. The height of the barriers also varied by participant. The study concludes by identifying that broad participation in demand response is likely to require a suite of incentivising approaches that appeal to different people, a key policy finding of interest to international agencies, government, public and private sector entities. - Highlights: • Novel study of financial incentive approaches for shifting residential energy. • First academic paper comprehensively identifying barriers to time of use tariffs. • First study reporting barriers to financial incentive approaches for demand response. • Incentive study design can be applied by government and energy companies.

Resilience improvements to UK nuclear power plants

International Nuclear Information System (INIS)

Pepper, Kevin

2015-01-01

Following the events at Fukushima, the Office for Nuclear Regulation (ONR), the UK nuclear safety regulator, undertook a series of reviews into the resilience of UK nuclear power plants to severe events. These reviews highlighted a number of areas in relation to electrical infrastructure where it considered licensees should review their arrangements, considering both onsite and offsite infrastructure as well as the ability to recover following a complete loss of site infrastructure. In response, UK licensees have been exploring four parallel approaches to improving the resilience for each of their sites. Firstly, through modifications on-site such as enhancements to the installed diesel generators and related systems. Secondly through improvements to the resilience of essential instrumentation to Station Black Out events. Thirdly, through the provision of off-site backup equipment that can be deployed to any site following a severe event. Finally, the provision of event qualified connection points on site to enable timely restoration of long term essential electrical supplies and cooling to key systems. This last item gives a central focus to the issues of switchboard availability and the resilience of the whole network to large potentially common cause internal and external hazards. This paper will discuss the electrically related findings of the ONR reviews, explore the reasoning behind those decisions, and describe the approaches being taken by UK licensees. (authors)

Energy Production System Management - Renewable energy power supply integration with Building Automation System

International Nuclear Information System (INIS)

Figueiredo, Joao; Martins, Joao

2010-01-01

Intelligent buildings, historically and technologically, refers to the integration of four distinctive systems: Building Automation Systems (BAS), Telecommunication Systems, Office Automation Systems and Computer Building Management Systems. The increasing sophisticated BAS has become the 'heart and soul' of modern intelligent buildings. Integrating energy supply and demand elements - often known as Demand-Side Management (DSM) - has became an important energy efficiency policy concept. Nowadays, European countries have diversified their power supplies, reducing the dependence on OPEC, and developing a broader mix of energy sources maximizing the use of renewable energy domestic sources. In this way it makes sense to include a fifth system into the intelligent building group: Energy Production System Management (EPSM). This paper presents a Building Automation System where the Demand-Side Management is fully integrated with the building's Energy Production System, which incorporates a complete set of renewable energy production and storage systems.

Domestic UK retrofit challenge: Barriers, incentives and current performance leading into the Green Deal

Dowson, Mark; Poole, Adam; Harrison, David; Susman, Gideon

2012-01-01

This paper reviews the thermal performance of the existing UK housing stock, the main fabric efficiency incentive schemes and the barriers to obtaining deep energy and CO 2 savings throughout the stock. The UK faces a major challenge to improve the thermal performance of its existing housing stock. Millions of dwellings possess ‘hard-to-treat’ solid walls and have glazing which is not cost effective to improve. A range of fabric efficiency incentive schemes exist, but many do not target the full range of private and social housing. From now on, the Green Deal will be the UK's key energy efficiency policy. However, the scheme is forecasted to have low consumer appeal and low incentives for investors. Moreover, calculated Green Deal loan repayments will be reliant upon estimated energy savings, yet it is claimed that retrofit measures may only be half as effective as anticipated due to a lack of monitoring, poor quality installation and the increased use of heating following refurbishment. Looking to Germany, there has been success through the Passivhaus standard, but the UK currently lacks appropriate skills and cost effective components to replicate this approach. In addition, the embodied energy in retrofit products and materials threatens to counter operational savings. - Highlights: ► CERT, CESP, Decent homes and Warm Front have not targeted the full extent of private and social homes. ► There is a risk that Green Deal will fail due to low consumer appeal and low incentives for investors. ► Up to half of the predicted energy savings from whole house retrofits may not be achieved in practice. ► Passivhaus is identified as best practice for retrofit, yet there is a lack of skills and components. ► Embodied energy in materials and components must be better understood to achieve life cycle savings.

The treatment of climate science in Integrated Assessment Modelling: integration of climate step function response in an energy system integrated assessment model.

Dessens, Olivier

2016-04-01

Integrated Assessment Models (IAMs) are used as crucial inputs to policy-making on climate change. These models simulate aspect of the economy and climate system to deliver future projections and to explore the impact of mitigation and adaptation policies. The IAMs' climate representation is extremely important as it can have great influence on future political action. The step-function-response is a simple climate model recently developed by the UK Met Office and is an alternate method of estimating the climate response to an emission trajectory directly from global climate model step simulations. Good et al., (2013) have formulated a method of reconstructing general circulation models (GCMs) climate response to emission trajectories through an idealized experiment. This method is called the "step-response approach" after and is based on an idealized abrupt CO2 step experiment results. TIAM-UCL is a technology-rich model that belongs to the family of, partial-equilibrium, bottom-up models, developed at University College London to represent a wide spectrum of energy systems in 16 regions of the globe (Anandarajah et al. 2011). The model uses optimisation functions to obtain cost-efficient solutions, in meeting an exogenously defined set of energy-service demands, given certain technological and environmental constraints. Furthermore, it employs linear programming techniques making the step function representation of the climate change response adapted to the model mathematical formulation. For the first time, we have introduced the "step-response approach" method developed at the UK Met Office in an IAM, the TIAM-UCL energy system, and we investigate the main consequences of this modification on the results of the model in term of climate and energy system responses. The main advantage of this approach (apart from the low computational cost it entails) is that its results are directly traceable to the GCM involved and closely connected to well-known methods of

As UK inches towards Chinese reactor project, China sets sights on new world markets

Shepherd, John [nuclear 24, St George' s Redditch (United Kingdom)

2017-02-15

Early in January, as many of us in Europe were getting back into the routine of returning to work following the festive period, a new chapter in the history of nuclear energy was already starting to be written in the UK. The UK government asked the country's nuclear regulators, the Office for Nuclear Regulation (ONR) and the Environment Agency, to start a generic design assessment (GDA) of what is now known as the 'UK HPR1000 reactor' - which is set to be the first deployment of Chinese reactor technology outside China. If the UK HPR1000 is eventually built in the UK, which would be at a designated site adjacent to the country's former Bradwell nuclear power plant in Essex, on the eastern coast, the project will not only be a first for the use of Chinese nuclear technology in any other country, it will ironically make UK ties with France stronger - at a time when the UK is preparing to break away from the European Union.

The structure of energy efficiency investment in the UK households and its average monetary and environmental savings

International Nuclear Information System (INIS)

Tovar, Miguel A.

2012-01-01

Socioeconomic and behavioural variables that influence the household’s adoption of energy efficiency measures such as cavity and loft insulation and upgrades to the boiler are identified, contrary to previous literature. By extending Brechling and Smith’s (1994) and Hassett and Metcalf's (1995) models, it is shown that the application of the Energy Act 2011, which contains provisions on the Green Deal, the new Energy Company Obligation (ECO) and the private rented sector, needs to follow a tailored strategy to reach the low adoption households identified by my model. Moreover, for the current adopters of the analysed measures, average monetary and environmental adoption benefits are estimated based on Parti and Parti’s (1980) demand model. These estimates are smaller than their expected values showing an important energy efficiency gap in the sector. Particularly low cost measures can bring important savings that can help to meet the ''pay as you save'' rule (i.e., the Golden rule) of the new regulation. My model also shows that a poor state of dwelling repair can reduce the adoption benefits increasing the need of subsidies that will be financed through consumer’s energy bills. However, this can increase the number of households in fuel poverty. - Highlights: ► Analysis of socioeconomic and behavioural factors that can affect the Green Deal uptake. ► The Energy Company Obligation (ECO) needs to follow a tailored strategy. ► Average adoption benefits of cavity and loft insulation and upgrades to the boiler are estimated. ► There is an important energy efficiency gap in the UK domestic sector. ► A poor state of dwelling repair could bring financial pressure to the ECO program.

Raising the temperature of the UK heat pump market: Learning lessons from Finland

International Nuclear Information System (INIS)

Hannon, Matthew J.

2015-01-01

Heat pumps play a central role in decarbonising the UK's buildings sector as part of the Committee on Climate Change's (CCC) updated abatement scenario for meeting the UK's fourth carbon budget. However, the UK has one of the least developed heat pump markets in Europe and renewable heat output from heat pumps will need to increase by a factor of 50 over the next 15 years to be in line with the scenario. Therefore, this paper explores what lessons the UK might learn from Finland to achieve this aim considering that its current level of heat pump penetration is comparable with that outlined in the CCC scenario for 2030. Despite the two countries’ characteristic differences we argue they share sufficient similarities for the UK to usefully draw some policy-based lessons from Finland including: stimulating new-build construction and renovation of existing stock; incorporating renewable heat solutions in building energy performance standards; and bringing the cost of heat pumps in-line with gas fired heating via a combination of subsidies, taxes and energy RD&D. Finally, preliminary efforts to grow the heat pump market could usefully focus on properties unconnected to the gas-grid, considering these are typically heated by relatively expensive oil or electric heating technologies. -- Highlights: •Heat pumps are expected to play a key role in meeting the UK's 4th carbon budget. •Today, heat pump deployment per capita in the UK is one of the lowest in Europe. •Finland offers some policy lessons given its high level of heat pump deployment. •Policies: raising build rates, building standards and heat pump cost-effectiveness. •Deployment efforts should focus on buildings not heated by relatively low-cost gas

The Nuclear Installations Inspectorate (NII) of the UK's Health and Safety Executive (HSE) has completed a review of their Safety Assessment Principles (SAPs) for Nuclear Installations recently. During the period of the SAPs review in 2004-2005 the designers of future UK naval reactor plant were optioneering the control and protection systems that might be implemented. Because there was insufficient regulatory guidance available in the naval sector to support this activity the Defence Nuclear Safety Regulator (DNSR) invited the NII to collaborate with the production of a guidance document that provides clarity of regulatory expectations for the production of safety cases for computer based safety systems. A key part of producing regulatory expectations was identifying the relevant extant standards and sector guidance that reflect good practice. The three principal sources of such good practice were: IAEA Safety Guide NS-G-1.1 (Software for Computer Based Systems Important to Safety in Nuclear Power Plants), European Commission consensus document (Common Position of European Nuclear Regulators for the Licensing of Safety Critical Software for Nuclear Reactors) and IEC nuclear sector standards such as IEC60880. A common understanding has been achieved between the NII and DNSR and regulatory guidance developed which will be used by both NII and DNSR in the assessment of computer-based safety systems and in the further development of more detailed joint technical assessment guidance for both regulatory organisations.

Allen, C; Francis, G; Martin, J; Boyce, M

2017-12-01

The aim was to review the use of The Over-volunteering Prevention System (TOPS) since the HRA began hosting it in 2013, and the Medicines and Healthcare products Regulatory Agency (MHRA) experience of monitoring its use by UK clinical research units. The HRA searched the TOPS database for the number, type and location of units and the number of entries. The MHRA inspectors reviewed their findings from routine inspections. Twenty-two additional UK units registered to use TOPS during 2013-2016, making a total of 84 units since TOPS was established in 2002. Use of TOPS is now a condition of research ethics committee approval of a phase 1 study and fulfils MHRA accreditation requirements for preventing over-volunteering. The total number of entries by all active units during 2013-2016 was 89,335, of which 84% were UK citizens and 16% non-UK citizens. The total number of entries during 2002-2016 was 249,612. Only 15 of 24,531 subjects (1/1600) and 18 of 18,745 subjects (1/1040) entered in 2015 and 2016, respectively, were deemed potential over-volunteers. The findings continue to support the concept that TOPS not only helps to prevent over-volunteering, but also deters subjects from trying to do so. Regulation of TOPS by the HRA and MHRA has enhanced its effectiveness, benefited all users and helped to improve the safety of volunteers who participate in non-therapeutic trials in the UK. The UK is still the only country with a national database to prevent over-volunteering that has published data on its widespread use and effectiveness.

A conceptual framework for exploring transitions to decarbonised energy systems in the United Kingdom

International Nuclear Information System (INIS)

Shackley, Simon; Green, Ken

2007-01-01

Drawing upon 'transitions theory' and a typology which produces five types of transitions, we describe and analyse the changes that have taken place in the United Kingdom's energy system over the past several decades in terms of three of these transition pathways, namely reproduction (e.g. incremental improvements in energy efficiency), transformation (e.g. more directed efforts towards energy efficiency gains, e.g., through voluntary and compulsory standards-setting processes) and substitution (e.g. the shift from coal to natural gas). Looking into the future, and drawing upon a programme of UK-based research which covered a wide range of potential new supply technologies and changes on the demand side, we identify the key drivers of change, including economic and commercial, technological, policy and regulatory imperatives. This analysis opens up the prospect for two further transition pathways to become manifest. These are: de-alignment/re-alignment (e.g. shift from conventional coal to coal technologies with carbon dioxide capture and storage) and re-configuration (e.g. integrating renewables within buildings and the possible emergence of the 'hydrogen economy'). We conclude with a discussion of the opportunities for policy learning and experimentation consistent with transitions theory to facilitate the deployment of more sustainable energy systems

Energy efficiency in U.K. shopping centres

Science.gov (United States)

Mangiarotti, Michela

Energy efficiency in shopping centres means providing comfortable internal environment and services to the occupants with minimum energy use in a cost-effective and environmentally sensitive manner. This research considers the interaction of three factors affecting the energy efficiency of shopping centres: i) performance of the building fabric and services ii) management of the building in terms of operation, control, maintenance and replacement of the building fabric and services, and company's energy policy iii) occupants' expectation for comfort and awareness of energy efficiency. The aim of the investigation is to determine the role of the above factors in the energy consumption and carbon emissions of shopping centres and the scope for reducing this energy usage by changing one or all the three factors. The study also attempts to prioritize the changes in the above factors that are more cost-effective at reducing that energy consumption and identify the benefits and main economic and legal drivers for energy efficiency in shopping centres. To achieve these targets, three case studies have been analysed. Using energy data from bills, the performance of the selected case studies has been assessed to establish trends and current energy consumption and carbon emissions of shopping centres and their related causes. A regression analysis has attempted to break down the energy consumption of the landlords' area by end-use to identify the main sources of energy usage and consequently introduce cost-effective measures for saving energy. A monitoring and occupants' survey in both landlords' and tenants' areas have been carried out at the same time to compare the objective data of the environmental conditions with the subjective impressions of shoppers and shopkeepers. In particular, the monitoring aimed at assessing the internal environment to identify possible causes of discomfort and opportunities for introducing energy saving measures. The survey looked at

The criticisms made by Sweet in his article 'Nuclear Power Costs in the UK' (Energy Policy; 6:107 (1978)) that assessments of nuclear power costs have been based on incorrect methods and assumptions are here answered. The particular points in the original analysis considered are; inflation, forecasts, load factors, generating costs, R and D costs, and benefits from a nuclear programme. It is stated that the published literature shows that nuclear power costs have for a long time been critically compared with the cost of alternatives, using well tried systems-analysis techniques and that the charge that 'mistaken' techniques have been employed is simply not sustained by the evidence. In reply Sweet objects that although his estimates have been criticised yet neither a direct rebuttal nor any alternative figures have been offered and significantly, his estimate that the official figures understate the true costs of nuclear power was not challenged. Particular aspects of the argument considered are; escalation of nuclear building costs, coal and nuclear generating costs, recovering R and D costs, and the 100 GW programme. (U.K.)

In 2003, the government in the United Kingdom tried to expand the amount of electricity generated from renewable sources. In addition to its longstanding target that 10 per cent of electricity should be supplied by renewables by 2010, the government's current goal is to achieve a target of 20 per cent by 2020. A number of policies and initiatives are now in place to help increase the present renewable electricity level of 3 per cent. These include the Renewables Obligation; the formulation of new approaches to electricity network regulation; modifications to the wholesale electricity market; and working to reduce barriers to renewables within the planning system. The impact of the 2010 targets on the UK's electricity system was assessed with a specific focus on regional approaches to renewable energy. A summary was presented of regional renewable energy assessments conducted in England and the devolved administrations in Scotland, Wales and Northern Ireland. The impact of regional targets on the national electricity transmission system were examined, as well approaches to implementation by newly established government bodies. A brief analysis of the geographical spread of renewable energy generation was presented. The South East of England was used as a case study to illustrate some the challenges faced by institutions. It was concluded that many barriers are still in place to renewable energy deployment, particularly within land-use planning, electricity market rules, and electricity market regulations. 25 refs., 3 tabs.

Objective To report on the career intentions, three years after qualification, of 12 national cohorts of UK-trained doctors who qualified between 1974 and 2012, and, specifically, to compare recent UK medical graduates' intentions to work in medicine in the UK with earlier graduates. Design Questionnaire surveys of cohorts of UK medical graduates defined by year of graduation. Setting UK. Participants 30,272 UK medical graduates. Main outcome measures Stated level of intention to pursue a long-term career in medicine in the UK. Results The response rate was 62% (30,272/48,927). We examined responses to the question ' Apart from temporary visits abroad, do you intend to practise medicine in the United Kingdom for the foreseeable future?' Of doctors from UK homes, 90% had specified that they would 'definitely or probably' practise medicine in the UK in the surveys of 1977-1986, 81% in 1996-2011 and 64% in 2015. Those who said that they would probably or definitely not practise medicine in the UK comprised 5% in 1977-1986, 8% in 1996-2011 and 15% in 2015. Most who were not definite about a future career in UK medicine indicated that they would wish to practise medicine outside the UK rather than to leave medicine. Conclusions The wish to remain in UK medical practice in the 2015 survey was unprecedentedly low in this unique series of 40 years of surveys.

Carbon capture and storage (CCS) is needed for meeting legally binding greenhouse gas emissions targets in the UK (ECCC 2016). Energy systems models have been key to identifying the importance of CCS but they tend to impose few constraints on the availability and use of geologic CO2 storage reservoirs. Our aim is to develop simple models that use dynamic representations of limits on CO2 storage resources. This will allow for a first order representation of the storage reservoir for use in systems models with CCS. We use the ECLIPSE reservoir simulator and a model of the Southern North Sea Bunter Sandstone saline aquifer. We analyse reservoir performance sensitivities to scenarios of varying CO2 injection demand for a future UK low carbon energy market. With 12 injection sites, we compare the impact of injecting at a constant 2MtCO2/year per site and varying this rate by a factor of 1.8 and 0.2 cyclically every 5 and 2.5 years over 50 years of injection. The results show a maximum difference in average reservoir pressure of 3% amongst each case and a similar variation in plume migration extent. This suggests that simplified models can maintain accuracy by using average rates of injection over similar time periods. Meanwhile, by initiating injection at rates limited by pressurization at the wellhead we find that injectivity steadily increases. As a result, dynamic capacity increases. We find that instead of injecting into sites on a need basis, we can strategically inject the CO2 into 6 of the deepest sites increasing injectivity for the first 15 years by 13%. Our results show injectivity as highly dependent on reservoir heterogeneity near the injection site. Injecting 1MTCO2/year into a shallow, low permeability and porosity site instead of into a deep injection site with high permeability and porosity reduces injectivity in the first 5 years by 52%.

Two energy visions, aimed at predicting future energy demand and consumption, are contrasted to explore the likely future blend of energy resources utilized. In the ''sustained growth'' model both supply and demand grow, reaching 150 GJ yr -1 per capita by 2060. In the ''dematerialisation'' model lower energy input technologies allow an energy use per capita of 90 GJ yr -1 by the same year. Fossil fuel use peaks at different times and renewable energy sources penetrate the market more thoroughly leading to a more diverse and robust world energy system. (UK)

Full Text Available This article examines the tension between the democratic right of public participation on specific environmental issues, guaranteed by European Law, and the degree to which it is being challenged in the UK as a consequence of recent approaches to energy infrastructure planning. Recent trends in UK government policy frameworks seem both to threaten effective public participation and challenge EU planning strategy, in particular those outlined in the Aarhus convention. The research outlined in this study involves an assessment of the changing context of planning and energy policy, in addition to recent changes in legislation formulation in the UK. The research findings, derived from an extensive interview process of elite stakeholders engaged in policy and legislation formulation in the UK and the EU provide a new categorisation system of stakeholders in energy policy that can be utilised in future research. The article concludes with a second order analysis of the interviewee data and provides solutions to increase public participation in the planning of energy infrastructure that emerge from the different perspectives.
