market based biogas sector development in least developed countries the case of cambodia in many of the least developed countries the energy security conundrum is how to provide affordable safe and clean energy to a low income rural population household level generation of biogas from animal waste for both cooking and lighting while producing high quality organic fertiliser is increasingly proposed as a viable part of the solution for farming households since the early 1990s international development organisations often in cooperation with the national government have attempted to introduce biogas technologies in many least developed countries but most initiatives failed in this landscape of failed biogas development programmes the national biodigester programme nbp cambodia started in 2006 with the aim to establish a permanent market oriented and self financed biogas sector the results show the development of a sustainable domestic biodigester sector a rapid diffusion of biodigesters among poor rural households but still ambivalences on financial independency from external funding and carbon finance the conclusion is that a pure market model for biogas development in the rural area of the least developed countries will not easily work governmental regulation and coordination will remain needed and carbon finance will not easily fully replace oda and governmental financial support

the co evolutionary relationship between energy service companies and the uk energy system implications for a low carbon transition abstract the energy service company esco business model is designed to reward businesses by satisfying consumers energy needs at less cost and with fewer carbon emissions via energy demand management and or sustainable supply measures in contrast the revenue of the incumbent energy utility company euco model is coupled with the sale of units of energy which are predominantly sourced from fossil fuels the latter is currently dominant in the uk this paper addresses two questions first why has the esco model traditionally been confined to niche applications second what role is the esco model likely to play in the transition to a low carbon uk energy system to answer these the paper examines the core characteristics of the esco model relative to the euco model the paper then examines how escos have co evolved with the various dimensions of the energy system i e ecosystems institutions user practices technologies and business models to provide insight into how escos might help to shape the future uk energy system we suggest that institutional and technological changes within the uk energy system could result in a more favourable selection environment for escos consequently enabling the esco model to proliferate at the expense of the euco model

the differential impact of low carbon technologies on climate change mitigation cost under a range of socioeconomic and climate policy scenarios this paper considers the effect of several key parameters of low carbon energy technologies on the cost of abatement a methodology for determining the minimum level of performance required for a parameter to have a statistically significant impact on co2 abatement cost is developed and used to evaluate the impact of eight key parameters of low carbon energy supply technologies on the cost of co2 abatement the capital cost of nuclear technology is found to have the greatest impact of the parameters studied the cost of biomass and ccs technologies also have impacts while their efficiencies have little if any sensitivity analysis of the results with respect to population gdp and co2 emission constraint show that the minimum performance level and impact of nuclear technologies is consistent across the socioeconomic scenarios studied while the other technology parameters show different performance under higher population lower gdp scenarios solar technology was found to have a small impact and then only at very low costs these results indicate that the cost of nuclear is the single most important driver of abatement cost and that trading efficiency for cost may make biomass and ccs technologies more competitive

politicians outside earnings and electoral competition this paper deals with the impact of electoral competition on politicians outside earnings in our framework politicians face a tradeoff between allocating their time to political effort or to an alternative use generating outside earnings the main hypothesis is that the amount of time spent on outside work is negatively related to the degree of electoral competition we test this hypothesis using a new dataset on outside earnings of members of the german federal assembly and find that politicians facing low competition have substantially higher outside earnings

patterns of political action committee contributions to the 1980 campaigns for the united states house of representatives our most robust findings can be summarized as follows u the spatial location of candidates is important in determining the pattern of campaign contributions many pacs and all pac types except agricultural cooperatives contribute in a manner highly consistent with a simple spatial model there is little giving by an individual pac to candidates at opposite ends of the dimension there is no instance of a pac contributing to incumbents located at each end of the dimension and only to challengers of incumbents in the middle or vice versa contributions against incumbents i e to challengers of incumbents are often spatial mirror images of a pac s giving in favor of incumbents though this statement must be tempered by the fact that the large majority of pacs give relatively little money to challengers few pacs give money to both challenger and incumbent in the same race giving in open seat races is if anything even more spatially consistent than in races where an incumbent is running while many individual pacs exhibit patterns of contributions consistent with the ideological dimension the data for 1980 suggest that there was no particular bias toward one end of the spectrum or the other taking all pacs together essentially eliminates the effect of the location variable in the regressions giving in races with an incumbent on the ballot was overall balanced across the dimension there are however ideological distinctions even among groups as broadly defined as the fec categories for the corporate labor and trade membership health groups the incumbent s location on the ideological dimension is an important explanatory variable even when other factors specific to the incumbent are considered of course ideology matters to nonconnected groups too they just tend to balance each other off in positive money though not in negative on average corporate and trade groups favor conservative incumbents and opponents of liberal incumbents labor pacs do the opposite except for labor pacs party is not an important variable in explaining positive contributions once the incumbent s voting record is taken into account for contributions to challengers however party is significant corporate nonconnected and trade pacs gave to opponents of democrats labor pacs did the opposite the expected closeness of the election is always an important variable both positive money and contributions to challengers increase as the probability of a strong challenge increases this suggests that pacs are sensitive to the potential impact of contributions on electoral outcomes although committee assignments have some importance in explaining campaign contributions by pac categories their net effect is never strong except in the case of cooperatives this is almost certainly because of the diversity of interests represented by pacs in every category except coops which are essentially one giant pac of milk producers we would surmise that competitive forces in the house result in most members having a portfolio of committee assignments that provides maximum advantage vis a vis each member s constituency it would therefore be surprising if overall committee assignments by themselves pointed to significant differences in generating campaign resources being chairman or ranking minority member of a committee has no impact on campaign contributions other things equal seniority as measured by number of consecutive years in office has a complicated role for positive contributions seniority has a nonmonotonic effect with contributions being higher for the most junior and most senior members ceteris paribus than for incumbents with average seniority negative contributions however are not significantly related to seniority

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

consumers in the green electricity market in finland abstract green electricity i e electricity produced from environmentally less harmful sources and marketed as such has been available to finnish households since 1998 but the demand for it has remained low in this paper we discuss the barriers identified by consumers to purchasing green electricity and contrast these with the interpretation energy sector actors give to consumer passivity the empirical material consists of thematic interviews energy policy actors often assume that consumers passivity signifies their lack of interest or low environmental consciousness this results partly from the failure to differentiate between the roles of consumer and citizen the interpretation the energy sector actors give to consumer passivity and the role they assign to consumers affect the direction of green electricity policy we argue that consumers need more information on both the environmental impact of different electricity products and in particular about the electricity supply and electricity contracts in a liberalised electricity market if they are to become active in the market

financial incentives to mobilise local citizens as investors in low carbon technologies a systematic literature review abstract mobilising greater levels of private finance through local citizen investment in low carbon technologies can help bridge the capital shortfall to meeting climate objectives while also building societal support for the low carbon transition within this context we undertake a systematic review of literature assessing the impact of technology specific economic and financial incentives promoting greater levels of investment in low carbon technologies from local citizen investors both individuals and community groups we focus in particular on the impact of feed in tariffs compared to quota schemes grants tax incentives and soft loans the analysis suggests that local citizen investors do not necessarily act in an economically rational manner in response to these incentives it underscores the importance of understanding the preferences of target demographics the local context as well as the characteristics of the technologies in question and suggests interventions should be considered as part of wider policy packages while identifying challenges to be overcome through instrument design we find that feed in tariffs grants and tax incentives can be successful in mobilising greater levels of investment from local citizen investors but that soft loans tend to be less effective as a stand alone instrument the review identifies areas meriting further exploration in this emerging field of research

seniority and anti competitive restrictions on the legislative common pool tenure s impact on the overall production of legislation and the concentration of political benefits it is well established that geographic areas benefit in terms of the share of government spending they capture from having a legislator with longer tenure holding constant the tenure of other legislators however the implications of this literature for how the total production of legislation changes if all members gained seniority is less clear increased levels and dispersion of seniority within congress generate a cartel like effect whereby legislators restrict the quantity of legislation enacted and increase the average price of each passed bill the analysis provides a natural experiment to gauge the impacts of the emergence of the congressional committee system

institutional design of public agencies and coproduction a study of irrigation associations in taiwan abstract the provision and production of many public goods and services involve the joint effort of government officials and citizen users this paper examines the successful experience of irrigation governance and management in taiwan as a means of understanding how joint efforts can be established and sustained through institutional arrangements several principles for institutional design including a careful definition of the scope of farmers participation complementarity of interests between individuals reduction of asymmetries involved in the use of authority and the existence of domains of autonomy are identified as instrumental to the success in taiwan

modelling electric vehicle usage intentions an empirical study in malaysia in the new global economy carbon emission has become an important worldwide issue one key reason for this is the magnification of the transport sector as millions of gasoline based vehicles are plying on roads producing carbon emission throughout day and night in order to impede these vulnerabilities and promote a more sustainable economy one solution is to switch from gasoline based vehicles to using green technology vehicles there is growing agreement that electrification and the ability to decarbonize this sector seems to be significant as it helps to mitigate the high reliance on fossil fuels and reduce carbon emissions the introduction of electric vehicles has led the automotive industry to a whole new echelon one with zero fuel dependency and increased fuel efficiency while the usage of greener and cleaner vehicles such as electric vehicles is well supported with government policies and programmes it is surprising that little information is divulged about the public acceptance of electric vehicles from the social perspective public acceptance and diffusion of this new green technology is relatively fresh and unknown in malaysia in fact public acceptance can appear as a prevailing obstacle for market diffusion and encumber the development of technology adoption the rationale of this paper is to conduct an exploration to determine the key predictors affecting the usage of electric vehicles acceptance in malaysia malaysia has been referred to here as electric vehicles are just being introduced as one of the initiatives to encourage a low fossil carbon technology within the transportation sector more specifically an empirical study using a survey questionnaire was distributed to 1000 private vehicle drivers in malaysia an electric vehicle usage model was proposed based on a literature review and a multiple regression model the results demonstrated that electric vehicles acceptance in malaysia can be explained as being significantly related to social influences performance attributes financial benefits environmental concerns demographics infrastructure readiness and government interventions in addition the study offers a valuable wealth of information on the public acceptance of automotive players planning to market electric vehicles in malaysia it also offers sensible guidelines for the formulation of marketing strategies that will address the real wants and needs of future electric vehicles users in the meanwhile policy makers should concentrate on the appropriate intervention and policy to encourage the development of electric vehicles as part of the strategy towards a transition to a low carbon society in malaysia

do green tech policies need to pass the consumer test the case of ethanol fuel abstract this paper investigates a question sometimes overlooked by policymakers and regulators namely the need of a robust value proposition for green technologies to successfully enter the market in particular results from consumer choice models are used to develop measures of consumer acceptance of ethanol blends and flex fuel vehicles is studied a fuel vehicle system that has received attention in a variety of federal and state policies the analysis suggests that under projected fuel prices and given the characteristics of the competing vehicle fuel systems consumers are unlikely to substitute ethanol blends for gasoline the analysis also highlights the need for further research in this area

reducing energy demand a review of issues challenges and approaches most commentators expect improved energy efficiency and reduced energy demand to provide the dominant contribution to tackling global climate change but at the global level the correlation between increased wealth and increased energy consumption is very strong and the impact of policies to reduce energy demand is both limited and contested different academic disciplines approach energy demand reduction in different ways emphasising some mechanisms and neglecting others being more or less optimistic about the potential for reducing energy demand and providing insights that are more or less useful for policymakers this article provides an overview of the main issues and challenges associated with energy demand reduction summarises how this challenge is framed by key academic disciplines indicates how these can provide complementary insights for policymakers and argues that a sociotechnical perspective can provide a deeper understanding of the nature of this challenge and the processes through which it can be achieved the article integrates ideas from the natural sciences economics psychology innovation studies and sociology but does not give equal weight to each it argues that reducing energy demand will prove more difficult than is commonly assumed and current approaches will be insufficient to deliver the transformation required

evaluating relative benefits of different types of r d for clean energy technologies clean energy technologies that cost more than fossil fuel technologies require support through research and development r d learning by doing relates historical cost decreases to accumulation of experience a learning investment is the amount of subsidy that is required to reach cost parity between a new technology and a conventional technology we use learning investments to compare the relative impacts of two stylized types of r d we define curve following r d to be r d that lowers costs by producing knowledge that would have otherwise been gained through learning by doing we define curve shifting r d to be r d that lowers costs by producing innovations that would not have occurred through learning by doing we show that if an equal investment in curve following or curve shifting r d would produce the same reduction in cost the curve shifting r d would be more effective at reducing the learning investment needed to make the technology competitive the relative benefit of curve shifting over curve following r d is greater with a high starting cost and low learning rate our analysis suggests that other things equal investments in curve shifting r d have large benefits relative to curve following r d in setting research policy governments should consider the greater benefits of cost reductions brought about by transformational rather than incremental change

capture and ideology in the economic theory of politics the economic theory of regulation long ago put public interest theories of politics to rest these theories have correctly been viewed as normative wishings rather than explanations of real world phenomena they have been replaced by models of political behavior that are consistent with the rest of microeconomics anthony downs 1957 james buchanan and gordon tullock 1965 george stigler 1971 sam peltzman 1976 recently however debate has arisen over whether some version of a public interest theory of regulation will have to be readmitted to our thinking about actions and results in the political arena what is at issue is the empirical importance of the altruistic publicly interested goals of rational actors in determining legislative and regulatory outcomes james kau and paul rubin 1979 kalt 1981 peltzman 1982 this study assesses the nature and significance of publicly interested objectives in a particular instance of economic policymaking u s senate voting on coal strip mining regulations the existence of such objectives is of course no contradiction of the economic view of human behavior kenneth arrow 1972 gary becker 1974 and may well be rooted in genetic biological history becker 1976 jack hirshleifer 1978 generally however individuals altruistic publicly interested goals have been given little attention this reflects the judgment that such goals are so empirically unimportant as to allow the use of occam s razor in positive models or well founded apprehensions that these goals are unusually difficult to identify measure and analyze notwithstanding the latter problem we find that approaches which confine themselves to a view of political actors as narrowly egocentric maximizers explain and predict legislative outcomes poorly the tracking and dissecting of the determinants of voting on coal strip mining policy suggest that the economic theory of politics has been prematurely closed to a broader conception of political behavior

feed in or certificates competition or complementarity combining a static efficiency and a dynamic innovation perspective on the greening of the energy industry abstract european policy on the greening of the energy industry has been characterised by a debate between proponents of two apparent polar opposites feed in tariffs and certificate markets different european countries have chosen both mechanisms and as a consequence the european union has maintained a fairly pluralist position abstaining from stricter harmonisation taking a dynamic innovation perspective on european energy industry we argue that feed in tariffs and certificate markets should not be seen as competing alternatives but rather as complementary regulatory instruments targeting subsequent steps in the product cycle on the way from early technology conceptualisation and development towards competitive positioning in mature energy markets we see both policy instruments as necessary to achieve the extensive transformation towards sustainable development that is judged as important tools in the context of the global climate challenge

factors influencing buying behaviour of green energy consumer green energy has gained significant research attention across the globe due to its ability to reduce environmental damage however for complete acceptance of green energy only government regulations are not enough the willingness to use green energy and contribute to the wellbeing of the environment should spring from within consumers such willingness may be developed by enhancing consumers perceived value of green energy however in order to do so it is necessary to assess existing levels of consumers perceived value towards green energy the present study develops a multidimensional green perceived value scale to measure existing levels of consumers perceived value the scale considers green perceived value as a multidimensional second order construct comprising functional value social value conditional value and emotional value dimensions such an attempt has not been made before which highlights the originality value of the present study the scale can be used to assess consumers perception towards green energy such information would help in formulating strategies that encourage consumers to voluntarily adopt green energy the study also reveals that it is not only the financial aspects that lead consumers to decide on adoption of green energy consumers are also driven by emotional and social considerations thus policy makers could formulate pro green energy programmes and mass messages that appeal to consumers sense of responsibility to voluntarily adopt green energy without having to rely on financial incentives researchers could examine the considered dimensions of the scale further with respect to other constructs related to consumer behaviour

renewable micro generation of heat and electricity review on common and missing socio technical configurations abstract a widespread adoption of distributed generation dg technologies in energy systems can play a key role in creating clean reliable energy and support the targets of emission reduction a transition from current modes of production to a significant deployment of renewable energy technologies can fundamentally affect the structure of the industry and change the way energy is produced transmitted and sold the current paper provides an extended review of the socio technical configurations of micro generation based on journal publications and reports during the 21st century the paper analyses currently existing and missing configurations and discusses technology and policy implications to support proliferation of micro generation technology and local energy production from renewable sources the potential for new configurations can be found particularly in heat producing micro generation with solar heat heat pumps and biomass developing further the operations and maintenance of distributed generation technologies and business models appears an area that calls for further innovation and corresponding innovation policy measures third party service and community driven deployment models can aide the proliferation of distributed generation and further innovation therein justifying the introduction of feed in tariffs to attract such models during their early diffusion

basic concepts for designing renewable electricity support aiming at a full scale transition by 2050 abstract renewable electricity supply is a crucial factor in the realization of a low carbon energy economy the understanding is growing that a full turn over of the electricity sectors by 2050 is an elementary condition for avoiding global average temperature increase beyond 2 c this article adopts such full transition as europe s target when designing renewable energy policy an immediate corollary is that phasing in unprecedented energy efficiency and renewable generation must be paralleled by phasing out non sustainable fossil fuel and nuclear power technologies the double phasing programme assigns novel meaning to nearby target settings for renewable power as share of total power consumption it requires organizing in the medium term eu wide markets for green power a highly demanding task in the present context of poorly functional markets in brown power the eu commission s 2007 2008 proposals of expanding tradable certificates markets were not based on solid analysis of past experiences and future necessities the keystone of sound policies on renewable electricity development is a detailed scientific differentiation and qualification of renewable electricity sources and technologies for measuring the huge diversity in the field we provide but structuring concepts about such qualification because implementation requires extensive research resources support for renewable electricity development is organized via feed in prices or premiums and via quota obligations connected to tradable green certificates green certificates are dependent on physical generated renewable power but separable and no joint products contrary to conventional wisdom we argue their separation in cost analysis but firm linking during trade a few graphs illustrate the importance of assigning qualities to different renewable power sources technologies feed in systems based on an acceptable qualification perform generally better than certificate markets imposing uniform approaches on a very diverse reality for a similar reason uniform and undifferentiated taxation of non sustainable energy sources cannot replace renewable energy support schemes capable of differentiation

motivational factors influencing the homeowners decisions between residential heating systems an empirical analysis for germany heating demand accounts for a large fraction of the overall energy demand of private households in germany a better understanding of the adoption and diffusion of energy efficient and renewables based residential heating systems rhs is of high policy relevance particularly against the background of climate change security of energy supply and increasing energy prices in this paper we explore the multi dimensionality of the homeowners motivation to decide between competing rhs a questionnaire survey n 2440 conducted in 2010 among homeowners who had recently installed a rhs provides the empirical foundation principal component analysis shows that 25 items capturing different adoption motivations can be grouped around six dimensions 1 cost aspects 2 general attitude towards the rhs 3 government grant 4 reactions to external threats i e environmental or energy supply security considerations 5 comfort considerations and 6 influence of peers moreover a cluster analysis with the identified motivational factors as segmentation variables reveals three adopter types 1 the convenience oriented 2 the consequences aware and 3 the multilaterally motivated rhs adopter finally we show that the influence of the motivational factors on the adoption decision also differs by certain characteristics of the homeowner and features of the home

geographies of energy transition space place and the low carbon economy this paper makes a case for examining energy transition as a geographical process involving the reconfiguration of current patterns and scales of economic and social activity the paper draws on a seminar series on the geographies of energy transition security climate governance hosted by the authors between 2009 and 2011 which initiated a dialogue between energy studies and the discipline of human geography focussing on the uk government s policy for a low carbon transition the paper provides a conceptual language with which to describe and assess the geographical implications of a transition towards low carbon energy six concepts are introduced and explained location landscape territoriality spatial differentiation scaling and spatial embeddedness examples illustrate how the geographies of a future low carbon economy are not yet determined and that a range of divergent and contending potential geographical futures are in play more attention to the spaces and places that transition to a low carbon economy will produce can help better understand what living in a low carbon economy will be like it also provides a way to help evaluate the choices and pathways available

can premium tariffs for micro generation and small scale renewable heat help the fuel poor and if so how case studies of innovative finance for community energy schemes in the uk abstract in the uk the introduction of micro generation feed in tariffs fits and a proposed renewable heat incentive rhi for domestic and small scale schemes have re energised the market for investment in domestic scale renewable energy these incentives may provide financial opportunities for those with capital to spend but for the record numbers with low incomes in fuel poverty these benefits may seem out of reach this paper shows that with appropriate financial intermediaries it is possible for renewable energy incentives to be used to alleviate fuel poverty simple financial analysis demonstrates the theoretical potential of fits to help those in fuel poverty two case studies of renewable energy projects in low income areas investigate how the incentives may be used in practice what barriers exist and what success factors are evident the analysis shows that local energy organisations leos are key if the poor are to access benefits from premium tariff schemes low interest finance mechanisms good information sharing and community involvement are found as key success factors

energy saving in swedish households the relative importance of environmental attitudes the objectives for energy saving in the housing sector set by recent swedish energy and climate policies are quite demanding this article uses nation wide swedish survey data from 2004 to 2007 to explore the potential for achieving those targets earlier findings that socio economic characteristics such as age housing type and income are strongly linked to higher propensities to save on heating and hot water usage are confirmed by ordered logistic regression models however general environmental attitudes are also found to play a crucial role when assessing the relative importance of socioeconomic factors and environmental attitudes the effect on energy saving is generally greater for the former than the latter in addition important interaction effects are identified in relative terms the effect of environmental attitudes is clearly stronger among households in apartment blocks than among those in detached housing and stronger among households with higher income than among those with lower income we end by discussing the implications for the selection and targeting of policy measures to tap the energy savings potential in the population

governing community energy feed in tariffs and the development of community wind energy schemes in the united kingdom and germany this paper analyses the development of community energy in the uk by comparing it to germany in relation to decentralisation scales and ownership structures particularly of wind energy varying approaches to energy generation at the community scale provide interesting insights into the impact of policy innovation as well as the capacity of national energy frameworks to foster socially innovative engagement practices beyond the purely technological diffusion of innovations by examining interactions between technological and social innovations with the help of a qualitative analysis opportunities for potential generators not traditionally engaged in energy generation to tap into these innovation systems are analysed this paper suggests that greater commitment to diversification beyond the implementation of policy measures such as the feed in tariff is required to provide communities with the capacity to develop new generation practices in terms of scale and ownership the uk in particular is struggling to protect these new generation practices which allow communities to derive benefits facilitated by specific energy policy measures according to their potential it concludes by indicating areas where niche protection might need to be expanded if community energy is to play a greater role in the uk s ambitious transition to a low carbon economy

differences in perception how the experts look at energy efficiency findings from a finnish survey abstract using energy efficiently is generally considered to be essential for a continuing prosperous future as a result improving efficiency has become a focus of attention and recently a lot of time and effort has been expended to develop new energy efficiency methodologies and technologies considering the amount of focused attention the rate of improvement has not been encouraging human behaviour is an important factor of the energy efficiency challenge and research has revealed several consumer profiles with significantly different perceptions on energy issues in this study the focus is not on consumers but on energy efficiency professionals a number of finnish energy efficiency professionals from both the private and public sectors were surveyed revealing that experts have decidedly different perceptions regarding energy efficiency our analysis of survey results suggests that energy efficiency expertise comes from a variety of educational and professional backgrounds and that instead of working on common ground experts with differing perspectives are endeavouring to make progress in a complex and multifaceted arena focusing on specific areas in which players need to share a common understanding of terminology and where common and clearly stated goals can be established should result in an acceleration of efficiency improvement results

nonconventional renewable energy governance in brazil lessons to learn from the german experience abstract this paper presents a comparative analysis of energy governance regarding nonconventional renewable energy sources ncres in brazil and germany brazil is a world leader in the use of conventional renewable energy sources such as hydro power while germany has been achieving outstanding results in fostering ncres the focus is on two critical issues the legal and regulatory framework and the institutions created to support the ncres market development the comparison shows that despite the very different energy situations and policy drivers valuables lessons can be extracted from the german experience the main lesson for brazil is to think ncres as a strategic opportunity to rely less on fossil fuel and large hydroelectric power plants to decentralize the electric power sector to use the huge solar biomass and wind power potential available in the country and to create a environment friendly ncres industry to this end three critical points were identified 1 the legal and regulatory framework should be improved 2 long term energy planning taking into account social economic and climate issues and 3 the current institutions supporting ncres in brazil should be upgraded and or new ones such as more specific energy agencies should be created

green products an exploratory study on the consumer behaviour in emerging economies of the east abstract the recent years have witnessed a phenomenal change in quantum and pattern of consumption in the developing nations of the east ever increasing consumption is putting a strain on the environment the present work delves into understanding the relationship between environmental concerns and consumer choice behaviour in purchasing green products in the context of india being a large emerging economy in south east asia attempt has been made to examine the influence of consumption values on sustainable consumer behaviour across consumer segments with preferential green choice approach difference multiple linear regression analysis one way analysis of variance and other standard statistical analysis of the data collected through questionnaire survey have been done results indicate that price sensitivity is high regardless of their choice preference social value parameter being the dominant factor influences sustainable consumption behaviour adoption among the green preferential cluster consumption values differ significantly across consumers exhibiting different preference for products with and without green credentials being higher for those with green purchase or consumption experience or notion

business models of heat entrepreneurship in finland abstract this paper presents the business models of small scale heat energy production in finland firstly the development of heat entrepreneurship in the country is presented including the remarkable growth of small and medium size enterprises smes in the last 15 years secondly the concept of business model business architecture of product service flows and earning logics is modified to the framework of wood heat production the business model concept and its sub concepts is applied in a brief review of current heat energy businesses in finland we arrive at a business model of heat entrepreneurships that are public companies utilities public private partnerships private companies and cooperatives energy saving company esco network model of large enterprise and franchising descriptive cases of these models are presented finally the paper concludes with a discussion on the applicability of the business models in different operational environments and geographical contexts

towards a contemporary approach for understanding consumer behaviour in the context of domestic energy use domestic sector energy use is increasing in the uk and currently accounts for 30 of total use policies of liberalised energy markets have allowed greater consumer choice but have not sought to reduce carbon emissions overall sales of energy efficiency products are rising but uk housing stock standards are poor and do not facilitate improved efficiency and further the sales of such products are influenced by their price thus the higher capital costs of products such as boilers and solar systems make them initially unattractive to consumers previous market based research into the adoption of energy efficiency products has often focused on single factors for example demographics this has limited the ability of policy makers to make informed decisions that address a broader range of factors such as individuals cognitive abilities values and attitudes as well as external factors such as social networks marketing and products and services this paper provides a wider critique of the theoretical base related to consumer behaviour product attributes and socio environmental theories that relate to energy use the aim of the paper is to draw together theories relevant to energy use in order to aid policy making in the broader context and to develop the discussion around integrated theories of consumer behaviour

energy paradox and political intervention a stochastic model for the case of electrical equipments abstract this paper develops a model that explains the delay of decisions to adopt profitable energy saving investments this problem is known as the energy paradox the model rationalizes the profitability requirements raised by the irreversibility the uncertainty and the decrease of costs as a result of learning by doing in this context the wait gives investors more visibility and more lower investment costs which gives them an option value the representative agent has an interest to postpone its energy saving decision until future benefits increase and equalize its required option value formally we internalize these explanatory factors in a stochastic model where the updated energy saving benefits follows a geometric brownian motion to affirm the capacity of the model we generate simulation results for two equipments for electrical uses beyond that we extend the model to simulate the effects of energy policy instruments to promote adoption of such equipments simulations prove that the taxation of energy prices is likely to be more effective than the subsidy for energy saving equipments it is also found that the combination of these instruments amplifies the adoption of energy saving equipments and generates very favorable economic and environmental externalities

review of barriers to the dissemination of decentralized renewable energy systems abstract this paper reviews the available literature dealing with the barriers to the dissemination of decentralized renewable energy systems decentralized renewable energy systems may face a range of technical economic institutional socio cultural and environmental barrier to their dissemination in the paper barriers impeding the dissemination of decentralized renewable energy systems have been identified and assessed in addition appropriate remedial measures and corresponding responsibility centers as reported in the literature have also been discussed inappropriateness of technology unavailability of skilled manpower for maintenance unavailability of spare parts high cost lack of access to credit poor purchasing power and other spending priorities unfair energy pricing lack of information or awareness and lack of adequate training on operation and maintenance of decentralized renewable energy systems are found to be the most critical barriers long term conducive policies appropriate regulatory framework financial incentives capital subsidies and soft loans to users technology and skill development internalization of externalities in the cost of energy withdrawal of subsidies presently being given to fossil fuels development of specialized institutions cooperation with international agencies participation of local community and awareness generation have been recommended for increased dissemination of decentralized renewable energy systems

not irrational but habitual the importance of behavioural lock in in energy consumption abstract a substantial body of literature has shown that our behaviour is often guided by habits the existence of habits not fully conscious forms of behaviour is important as it contradicts rational choice theory their presence thus calls for the setting of new instruments as they make it unlikely that consumers be capable of exercising control over their energy consumption in reaction to given incentives this is further increased in the evolutionary perspective where the current carbon based socio technical system constrains and shapes consumers choices through structural forces habits being potentially counterintentional they may explain the efficiency paradox in energy as well as the continued increase of energy consumption despite the rising environmental awareness among the population policies aiming at reducing energy consumption should thus specifically address the performance context of habits for instance targeting new residents has proven to be more effective given that their preceding habits have been disturbed the results of our empirical analysis confirm this idea by showing how a change of context makes people more receptive to a proposed measure our analysis of the role played by habits also suggests that individuals do not consider the need to change existing habits as an obstacle even though this is contradicted implicitly in the answers they provided to open questions this unconsciousness is one of the most delicate features of habits and it should thus be accounted for when designing measures given the other characteristics of habits the joint use of feedbacks and commitment strategies appears promising

purchasing intentions of chinese citizens on new energy vehicles how should one respond to current preferential policy in recent years china s environmental pollution and energy security issues have become increasingly more prominent as a result new energy vehicles nevs have been strongly supported by government s policy privilege but at this stage these preferential policies are facing updates and adjustments to meet the current development of nev industry and consumer demand of purchase this means that an understanding of the nev purchasing behavior in china what the current policy is and how to respond to its adjustment are of theoretical and practical significance for china s nev industry to this end a reliable scale is developed in this study to investigate the situation in seven chinese geographical regions and 22 provinces based on application of an extended theory of planned behavior model to the real situation a structural equation model is used to analyze the factors affecting the nev purchasing intentions of residents the results show that financial benefits infrastructure readiness environmental concerns and policy privileges have a positive impact on purchasing intention however the nev s cruising range does not based on the paper s findings we have discussed whether current subsidies and preferential policies reflect consumers potential purchase demand how to make subsidies more tangibly targeted and thereby present some proposals for manufacturing strategy under the influence of policy and demand of consumers

a public perspective on the adoption of microgeneration technologies in new zealand a multivariate probit approach the growing demand for electricity in new zealand has led to the construction of new hydro dams or power stations that have had environmental social and cultural effects these effects may drive increases in electricity prices as such prices reflect the cost of running existing power stations as well as building new ones this study uses canterbury and central otago as case studies because both regions face similar issues in building new hydro dams and ever increasing electricity prices that will eventually prompt households to buy power at higher prices one way for households to respond to these price changes is to generate their own electricity through microgeneration technologies mgt the objective of this study is to investigate public perception and preferences regarding mgt and to analyze the factors that influence people s decision to adopt such new technologies in new zealand the study uses a multivariate probit approach to examine households willingness to adopt any one mgt system or a combination of the mgt systems our findings provide valuable information for policy makers and marketers who wish to promote effective microgeneration technologies

peak electricity demand and social practice theories reframing the role of change agents in the energy sector abstract demand managers currently draw on a limited range of psychology and economic theories in order to shift and shed peak electricity demand these theories place individual consumers and their attitudes behaviours and choices at the centre of the problem this paper reframes the issue of peak electricity demand using theories of social practices contending that the problem is one of transforming technologically mediated social practices it reflects on how this body of theory repositions and refocuses the roles and practices of professions charged with the responsibility and agency for affecting and managing energy demand the paper identifies three areas where demand managers could refocus their attention i enabling co management relationships with consumers ii working beyond their siloed roles with a broader range of human and non human actors and iii promoting new practice needs and expectations it concludes by critically reflecting on the limited agency attributed to change agents such as demand managers in dominant understandings of change instead the paper proposes the need to identify and establish a new group of change agents who are actively but often unwittingly involved in reconfiguring the elements of problematic peaky practices

the value of social networks in the diffusion of energy efficiency innovations in uk households abstract 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

sustainability assessment of renewable energy projects for off grid rural electrification the pangan an island case in the philippines abstract renewable energy systems ress have been promoted for rural electrification as an answer to the growing energy needs of communities while simultaneously satisfying environmental and resource scarcity problems these off grid systems however have several challenges in the perspective of sustainability due to the technically and financially weak recipients and users of the projects there is still however less detailed understanding how the technical and economic aspects of the projects can properly match the social aspects to promote sustainability this paper aimed to further understand the challenges and social impacts of rural electrification projects using res through a case study of a centralized off grid solar plant in the philippines the study used multiple correspondence analysis mca to identify essential user attributes which explain the users electricity consumption behaviors the community cooperative had difficulties maintaining the facility in the long term due to financial and capacity related challenges a holistic approach dealing with the technical economic and social aspects in developing res projects promote sustainability

the mediating role of social workers in the implementation of regional policies targeting energy poverty abstract this paper aims to provide a socio political reflection of the role played by social workers in regional policies and of the real needs of households affected by energy poverty the paper also examines the impact of technical specialised training on the ability of social workers to prevent and mitigate conditions of household energy poverty in europe the adoption of a research action participation methodological framework and a training research approach has permitted the opinions of social workers to be collected through surveys and their central role in implementing regional policies to be highlighted the conclusions obtained have made possible the construction of a self diagnosis and data collection tool which increases the ability of social workers to mediate and implement urgent mitigation measures for energy poverty finally regional policies which aim to mitigate household energy poverty are examined from the professional perspective of social workers

domestic micro generation economic regulatory and policy issues for the uk abstract micro generation in individual homes has been the subject of increasing policy and industry attention in recent years whilst it has been estimated that micro generation could meet 30 40 of uk electricity demand by 2050 deployment to date has been slow in its micro generation strategy the uk government has started to outline how deployment could be increased various technical economic behavioural and institutional changes are needed to establish a uk market for micro generation this article discusses how different deployment models for domestic micro generation might attract investments in these technologies it considers not only investments by individual households but also by energy companies starting from an economic analysis of payback times for three different technologies micro chp micro wind and solar pv it identifies policy and regulatory recommendations it argues for technology specific support policies in the short term it also suggests that a level playing field for micro generation technologies as a result of fiscal and market reforms could considerably increase the attractiveness of micro generation technologies

household preferences for cooking fuels and inter fuel substitutions unlocking the modern fuels in the nepalese household different cooking fuels are associated with various economic and environmental challenges such as increased economic costs indoor air pollution deforestation and deterioration of public health in this study we assess the impact of various socioeconomic factors in a household s cooking fuel choice and motive for making a transition toward cleaner fuels this study uses household level cross sectional data 2011 and pooled data 1996 2004 and 2011 from the nepal living standard survey we use multinomial and binomial logit models for the empirical analysis the results suggest that along with household income other social and ecological factors play a critical role in inter fuel switching decisions we find that transferring property rights of government owned forests to the communities encourages households to move towards cleaner cooking fuels we also find that household head s education distance to the firewood sources energy access status and household income are significant factors influencing the households fuel choice decisions the policy implication is that increasing information spillover involving local communities in forest management and expanding alternative socioeconomic opportunities such as jobs and modern fuels in the remote regions play a vital role in encouraging the households to move towards cleaner energy sources

consumer attitudes towards domestic solar power systems the success of the uk policy to reduce carbon emissions is partly dependent on the ability to persuade householders to become more energy efficient and to encourage installation of domestic solar systems solar power is an innovation in the uk but the current policy of stimulating the market with grants is not resulting in widespread adoption this case study using householders in central england investigates householder attitudes towards characteristics of solar systems and identifies some of the barriers to adoption the study utilises diffusion of innovations theory to identify attitudes towards system attributes and isolates the characteristics that are preventing a pragmatic early majority from adopting the technology a group of early adopters and a group of assumed early majority adopters of solar power were surveyed and the results show that overall although the early majority demonstrate a positive perception of the environmental characteristics of solar power its financial economic and aesthetic characteristics are limiting adoption differences exist between the two groups showing support for the concept of a chasm between adopter categories after moore crossing the chasm marketing and selling high tech products to mainstream customers second ed harper perennial new york however if consumers cannot identify the relative advantage of solar power over their current sources of power which is supplied readily and cheaply through a mains system it is unlikely that adoption will follow recommendations concerning the marketing and development of solar products are identified

institutional influences on business model choice by new ventures in the microgenerated energy industry abstract business model choice plays an important source of competitive advantage for new ventures in the microgeneration sector yet existing literature focuses on strategic management of internal resources as the constraints in this choice process in the energy sector external factors may be at least as influential in shaping these business models this paper examines the roles of politico institutional and socio institutional dynamics in the choice of business models for microgeneration ventures business models have traditionally been viewed as constructions of the internal values strategies and resources of organizations but this perspective overlooks the role that external forces have on these models particularly in more highly institutionalized contexts like microgeneration when these factors are introduced into the existing framework for business model choice the business model based less on firm decision making and more about variables that exist within national innovation systems and political structure local socio technological conditions and cognitive abilities of the entrepreneur and corresponding stakeholders

an energy pricing scheme for the diffusion of decentralized renewable technology investment in developing countries the purpose of this paper is to investigate price support for market penetration of renewable energy in developing nations through a decentralized supply process we integrate the new decentralized energy support renewable premium tariff to analyze impacts of tariff incentives on the diffusion of renewable technology in senegal based on photovoltaic and wind technologies and an assessment of renewable energy resources in senegal an optimization technique is combined with a cash flow analysis to investigate investment decisions in renewable energy sector our findings indicate that this support mechanism could strengthen the sustainable deployment of renewable energy in remote areas of senegal although different payoffs emerged profits associated with a renewable premium tariff are the highest among the set of existing payoffs moreover in analyzing impacts of price incentives on social welfare we show that price tariffing schemes must be strategically scrutinized in order to minimize welfare loss associated with price incentives finally we argue that a sustainable promotion of incentive mechanisms supporting deployment of renewable technology in developing nations should be carried out under reliable institutional structures the additional advantage of the proposed methodology is its ability to integrate different stakeholders producers investors and consumers in the planning process

energy poor or fuel poor what are the differences abstract energy poverty and fuel poverty are descriptors of problems of households energy consumption they are both distinct problems and have been addressed by many researchers organizations and governments cross use of the terms of energy poverty and fuel poverty in published papers is common as an accurate descriptor is the presupposition of research and policy development especially for those who just started to pay attention to this issue this paper compares the definitions research priorities status quo and problems of these two concepts and summarizes the relationship between them the paper suggests that only when the research targets are households who are living in a cold climate and have difficulty in getting access to electricity or modern cooking facilities and in supplying indoor heating with appropriate cost the concepts of energy poverty and fuel poverty have the chance to be broadened and mutually integrated

ghg reduction potential of changes in consumption patterns and higher quality levels evidence from swiss household consumption survey abstract an effective consumer oriented climate policy requires knowing the ghg reduction potential of sustainable consumption the aim of this study is to draw lessons from differences in consumption between households with high and low ghg emissions we evaluate a survey of 14 500 households and use a method that allows measuring changes in price level of consumption comparing the 10 of households with the highest ghg emissions per capita with the lowest 10 controlling for differences in expenditure level and household structure we find a range 5 17 tons of co2 equivalent per capita and year the observed differences stem mainly from heating electricity use car use and travel by aircraft consumption patterns with low ghg emissions are characterized by less spending on mobility but more on leisure and quality oriented consumption leading to higher prices per unit further characteristics are a higher share of organic food low meat consumption and fewer detached single family houses our findings imply that a significant reduction in ghg emissions would be possible by adopting real world consumption patterns observable in society the twin challenge is to shift consumption towards more climate friendly patterns and to prevent any trend towards high emitting consumption patterns

the economics of distributed energy generation a literature review the uk electricity system is likely to face dramatic technical and institutional changes in the near future current uk energy policy focuses on the need for a clean affordable and secure energy supply decentralisation of the electricity system is recognised as one means of achieving efficient and renewable energy provision as well as addressing concerns over ageing electricity infrastructure and capacity constraints in this paper we provide a critical literature review of the economics of increased penetration of distributed energy generation we find that there exists a large volume of research considering the financial viability of individual distributed generation technologies and we are necessarily selective in our review of these studies given the wide variety of technologies that the definition of distributed generation encompasses however there are few studies that focus on the pure economics of individual or groups of distributed energy generators and even fewer still based on the economy wide aspects of distributed generation in view of this gap in the literature we provide suggestions for future research which are likely to be necessary in order adequately to inform public policy on distributed generation and its role in the future of uk energy supply

u s energy research and development declining investment increasing need and the feasibility of expansion investment in energy research and development in the u s is declining despite calls for an enhancement of the nation s capacity for innovation to address environmental geopolitical and macroeconomic concerns we examine investments in research and development in the energy sector and observe broad based declines in funding since the mid 1990s the large reductions in investment by the private sector should be a particular area of concern for policy makers multiple measures of patenting activity reveal widespread declines in innovative activity that are correlated with research and development r d investment notably in the environmentally significant wind and solar areas trends in venture capital investment and fuel cell innovation are two promising cases that run counter to the overall trends in the sector we draw on prior work on the optimal level of energy r d to identify a range of values which would be adequate to address energy related concerns comparing simple scenarios based on this range to past public r d programs and industry investment data indicates that a five to ten fold increase in energy r d investment is both warranted and feasible

analysis of consumer choice for low carbon technologies by using neural networks abstract through a modelling based contribution this paper critically reviews and explores the impact of low carbon heat policies to induce technological policy development the paper interrogates an irish government funded sustainable energy financed scheme the greener homes scheme launched in 2006 and aimed at the deployment of low carbon technology in the residential sector this paper analyses 31 560 technology installations supported under this scheme and it utilises artificial neural network modelling as a method of better analysing and understanding the effects relationships and dependencies that influence consumer decision making and responses to new technological policies it is responding to a perceived limited understanding of the variables that influence a wider adoption of low carbon technologies and the opportunities and potential that could result in a wider appreciation of the broader impact of market barriers it builds up on the artificial neural networks modelling work explores its application in pattern recognition and interprets its influence in predicting customer behaviour the paper provides an enhanced understanding of the various factors that influence consumer selection of one low carbon technology over another evaluation of the results revealed that the developed artificial neural network model generic 7 6 4 neurons layered architecture is the most appropriate tool and suitable network in predicting indices based on certain social conditions on the choice of certain low carbon technologies

sustainability guided promotion of renewable electricity generation in recent years the threat of global climate change high fuel import dependence and rapidly rising electricity demand levels have intensified the quest for more sustainable energy systems this in turn has increased the need for policy makers to promote electricity generation from renewable energy sources guaranteed prices coupled with a buy back obligation for electricity fed into the grid is a popular renewables promotion instrument especially in europe more recently driven mainly by electricity market liberalisation efforts quota targets for the share of renewables in combination with tradable green certificates tgc have received considerable attention tgc offer a greater theoretical potential for economic efficiency gains due to price competition and the greater flexibility assigned to the obliged parties while guaranteed prices and tgc schemes support the operation of renewable energy technology systems bidding schemes for renewable energy generation capacity are used to raise economic efficiency on the plant construction side all of these policy instruments suffer from the shortcoming that they do not explicitly account for the often widely varying environmental social and economic impacts of the technologies concerned in this paper we propose a methodology for the design of renewable energy policy instruments that is based on integrated assessment in particular we argue that using participatory multicriteria evaluation as part of the design of renewable energy promotion policies would make it possible 1 to differentiate the level of promotion in a systematic and transparent manner according to their socio ecological economic impact and 2 to explicitly account for the preferences of stakeholders a further problem of existing tgc and bidding schemes is that diversity of supply could be severely diminished if few low cost technologies were allowed to dominate the renewable energy market to ensure a certain diversity of technologies our scheme suggests the use of different technology bands for technologies that are relatively homogeneous with respect to their maturity

the distribution of honoraria income in the u s congress who gets rents in legislatures and why the major conclusion to be drawn from this analysis is that low cost suppliers of political favors receive the highest honoraria incomes there is no evidence that being a lawyer acquiring a large number of committee assignments receiving high ratings by labor unions representing a safe district or introducing numerous legislative bills increases one s honoraria income in any significant way the wider dispersal of power reduces the effects of seniority and membership on the finance committee in determining institutional power in the senate hence these variables are only significantly related to honoraria income in the house the smaller the number of suppliers in the senate relative to the house means that senators obtain higher prices for their services as a result business groups are more willing to pay extra a price premium to assure that no shirking occurs

an affinity to commons model of public support for environmental energy policy abstract as atmospheric co 2 continues to rise above 450 ppm policymakers struggle with uncertainty concerning predictors of citizen support for environmental energy policies eeps and preferences for their design topics which have received limited attention in empirical literature we present an original model of policy support based on citizens affinity to commons pathways by which individuals enjoy natural public goods that in turn shape preferences between alternative policy mechanisms we evaluate this model using a survey of southern california electricity customers with results indicating the model s utility in predicting public support of eep stronger community ties are associated with preferences for pull type subsidies whereas stronger connections to natural commons are linked to support for both pull and push type sanctions findings have implications for coalition building as advocates may engender support for green energy policy by framing sanctions as protecting natural commons and framing subsidies either in this same way and or as producing benefits for communities

the patchy spread of renewables a socio territorial perspective on the energy transition process abstract in the energy transition process the district heating networks and the wind power facilities play a key role these two technologies can contribute to establish models of co provision involving new social actors in the energy field despite that the socio organizational change appears patchy in italy these options are dominated by large utilities and the few forms of energy co production are to be found in specific contexts the influence of socio territorial features on the energy transition seem relevant this paper aims analysing energy transition while focusing on the institutional relational and territorial dimensions to unfold how energy innovations take place within territorial contexts in this respect energy transition is investigated considering both the district heating and the wind power in italy the analysis suggests that the transition is influenced by the way in which territorial context is destabilized by the perturbations of energy landscape

dissemination of solar photovoltaics a study on the government programme to promote solar lantern in india abstract the study examines the reasons for the limited dissemination of solar lanterns in india it uses diffusion of innovation framework to examine the dissemination process the impact of the characteristics of solar lantern on dissemination and also the communication within the community about the product are examined to understand the influence of the characteristics of solar lantern on dissemination and the information source used by adopters a survey of 188 users across 15 locations is carried out the study shows that the benefits promoted by the government programme for disseminating solar lantern are not the reasons for purchase in most cases the results suggest that the emphasis on subsidy by the support programme shifts the focus to the cost of the solar lantern than its benefits contrary to expectation there is no significant difference in the profile of early and late adopters the subsidy for solar lanterns and the targets set for government officials are the possible influence on the observed profile for adopter categories the early majority who can afford the solar lantern and take up the innovation on its merits are expected to disseminate the innovation the programme on the contrary not only fails to identify and promote to the early adopters but focus on the disadvantaged groups there are therefore no champions for the innovation and an absence of word of mouth communication the information source is restricted to government agencies while the potential user looks for evaluative information on the product from existing users the application of diffusion of innovation framework to understand the dissemination process of solar lantern suggests reworking the support programmes designed to promote solar lanterns the lessons can be extended to programmes designed for dissemination of other solar photovoltaic products

structural dynamics of innovation networks funded by the european union in the context of systemic innovation of the renewable energy sector innovation in the renewable energy re sector relies on the concept of systemic innovation which requires interaction between two innovation aspects technology exploration and market exploitation the european union eu has introduced political instruments for systemic re innovation by integrating resources from different thematic and geographic areas however using these instruments to establish an ecosystem for systemic innovation remains unexplored this study develops a framework for evaluating the systemic innovation performance of networks through a time series analysis of network structural properties overall eu funded innovation networks have not evolved in a systemic direction first the network exhibits densely connected local clusters for technology exploration and market exploitation of re innovation which are disconnected from each other over time the gap between the two phases has weakened with increasing connectivity but the local clusters supporting either explorative or exploitative activities have diminished the existing networking linkages among organizations are considered ineffective because their positions in the network tend to display a mismatch with their innovation patterns this research presents policy suggestions for optimizing the exploration and exploitation activities in the eu s funding program and their complementarities to establish a systemic innovation environment in the re sector

co provision in sustainable energy systems the case of micro generation 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

the deployment of decentralised energy systems as part of the housing growth programme in the uk abstract 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

energy equity and the future of the fuel poor abstract a warm and adequately lit home is considered a basic need together with access to energy consuming appliances ranging from a fridge to a tv an underlying tenet of sustainable energy is that such basic needs should be affordably met yet low incomes energy inefficient housing and appliances and high energy costs mean that roughly 10 per cent of uk households many of them elderly or with young children fail to attain this basic standard these households which would need to spend more than 10 per cent of their income to attain adequate energy services are officially defined as fuel poor their cold poorly equipped homes lead to chronic cold related health conditions exacerbate social isolation and may undermine educational achievement in addition rural areas have a disproportionately high incidence of fuel poverty this review examines the current distribution of energy consumption its social impacts and the opportunities to address fuel poverty through improvements to the housing stock it will then consider potential future developments

explaining legislators positions on outside income limits voting on honoraria ceilings in the u s senate 1981 1983 this article examines roll call voting by members of the u s senate on three proposals to limit members outside income in the 1980s i find that several factors influenced legislators votes on outside income limits legislation oill first financial self interest was an important constraint on members willingness to support oill members who earned more honoraria were less likely to vote yes but this opposition was neutralized when limits were attached to the compensating mechanism of a pay raise senators from poorer states were generally more likely to support honoraria limits alone but less likely to support limits linked to a pay raise suggesting a responsiveness to constituent interests in both cases finally when oill was linked to a pay raise electoral considerations became prominent in legislators vote decisions with electorally vulnerable members less likely to vote yes

a simple test of the thesis that committee jurisdictions shape corporate pac contributions the results presented in the previous section tend to confirm the hypothesis that committee assignments shape the pattern of corporate pac contributions this note corroborates existing research on corporate pacs at a significantly lower level of aggregation than the samples on which existing research has been conducted further because a nonparametric test was used rather than the more standard regressional analysis these results should increase our confidence that the essential institutions of government affect and engender responses by economic agents

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

the negative impacts of the global economic downturn on funding decentralised energy in the uk abstract 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

utilities business models for renewable energy a review abstract the transformation of today s electric power sector to a more sustainable energy production based on renewable energies will change the structure of the industry consequently utilities as the major stakeholders in this transformation will face new challenges in their way of doing business they will have to adapt their business models to remain competitive in the new energy landscape the present review of business model literature shows that two basic choices exist utility side business models and customer side business models the two approaches follow a very different logic of value creation while the former is based on a small number of large projects the latter is based on a large number of small projects the article reveals that blueprints for utility side business models are available whereas customer side business models are in an early stage of development applying the business model framework as an analytical tool it is found that existing utility side business models comprise a series of advantages for utilities in terms of revenue potential and risk avoidance this study provides new insights about why utilities will favor utility side business models over customer side business models and why they also should engage in customer side business models in their quest for more sustainable future business models

green electricity policies in the netherlands an analysis of policy decisions over the last decades fundamental changes can be observed in both market conditions and the national policy framework for green electricity in the netherlands the dutch government has regularly intervened in markets demonstrating fundamental shifts in policy and approach this study aims to analyse the developments in renewable energy policy making in the netherlands it assesses changes in the choice of policy instruments and target groups the role of stakeholders and offers explanations behind policy successes and failures dutch green electricity policy over the last decade can be characterised roughly by three phases in the early 1990s the government negotiated voluntary agreements with the energy distribution sector on targets for green electricity sales which were never met in the second half of the 1990s a regulatory energy tax was introduced from which customers of green electricity were exempt this led to a substantial increase in demand which was largely met by green electricity imports and did not lead to additional domestic renewable energy capacity finally a change in policy has taken place recently 2003 shifting the focus from promotion of demand to the promotion of supply through a system of regulated feed in tariffs despite the renewable energy policies growth of the renewable energy market in the netherlands has been small and targets have not been fully met the dutch government has not yet succeeded in substantially reducing market uncertainties and in building confidence among market parties because the policies have not been stable and policy objectives have frequently been partly ambiguous in addition the influence of stakeholders in renewable energy policy making has been small which has the early acceptance and implementation of alternative policies
