market segmentation and willingness to pay for green electricity among urban residents in china the case of jiangsu province the objective of this study is to identify market segments and estimate the residents willingness to pay wtp for green electricity green e in china for the large scale promotion of energy projects from renewable sources that do not rely solely on energy policies based on an analysis of non use values of green e as well as the application of the contingent valuation cv method and payment card pc introduction technology the average wtp ranges from rmb 7 91 yuan month to 10 30 yuan month approximately us 1 15 1 51 month with an exchange rate of 6 83 yuan us yuan us for urban residents in jiangsu province the current work also explores the differences in demographic variables across varying wtp amounts and the different marginal effects of demographic variables at the same level of wtp the findings reveal that there are significant differences in demographic variables such as level of education household income and location of residence across the population segments moreover the finding that some respondents with high income and higher education prefer higher wtp amounts to lower wtp amounts suggests that green e is a luxury product and consequently a veblen effect exists in certain chinese market segments

public preferences for investments in renewable energy production and energy efficiency abstract in this paper we investigate the choices citizens make when asked to express willingness to support a proposed energy policy and are then compelled to allocate the program funds to either renewable energy or energy efficiency in a survey study based on a random sample of residents of the state of maine usa we find that citizens have preferences for specific types of renewable energy but these preferences do not yield significantly different allocation of investment funds between renewable energy and energy efficiency we find that preferences are generally consistent regardless of presentation of options i e limited ordering effects our results also indicate that personal characteristics that are understudied in the energy literature including promotion prevention focus and social fiscal leanings influence both willingness to support energy policies and also their allocation of fund choices but in different ways this suggests the importance of including multiple options in energy policy proposals and that targeted messages regarding the components of such policies is key for optimal communication

diffusion of green power products in switzerland abstract as in many other european countries green electricity is an emerging product in switzerland as well although the market is yet to be liberalised more than 100 of the 1200 swiss electric utilities offer some sort of green electricity product to their customers successful companies like the municipal utilities of the cities of zurich and berne have reached customer response rates of up to 4 while still maintaining cost based pricing i e charging their customers price premiums of 400 700 per kwh while most of the products still rely on mainly photovoltaics some utilities have started to introduce mixed green electricity products also including wind power with a share of 60 in the swiss generation mix hydropower s role in the green electricity mix was also an issue to emerge causing controversial debate while being renewable hydropower is not considered environmentally benign by all the stakeholders and unlike new renewables solar wind biomass there is little room for new hydropower generation facilities in switzerland the green electricity labelling scheme naturemade tackles that issue the labelling organisation has evolved from a process with broad stakeholder involvement which included environmental ngos scientific institutions green electricity providers renewable energy advocates government bodies and consumer organisations the analysis in this paper is based on a diffusion theory framework it identifies and characterises different phases of past and future market development and stresses the importance of eco labelling as a tool to facilitate the transition from niche to mass market finally we also discuss conclusions that can be drawn from the swiss case towards market development and labelling on a european level

a target group specific approach to green power retailing students as consumers of renewable energy an extensive body of literature exists on the obstacles that have to be overcome in green power retailing in this article target group specific marketing is evaluated as a strategy to increase the share of residential customers of green power a sample of students in the city of freiburg germany was interviewed in order to assess their awareness of environmental issues their willingness to change to green power products and to better understand individual hindrances in changing the power supplier the analysis shows that students are highly positive towards green power products but for several reasons difficult to reach in marketing campaigns aspects to be considered in addressing this consumer group include the students particular expectations towards green products their living conditions price sensitivity and their perception of the relative effort involved in changing the power provider

the effects of moral licensing and moral cleansing in contingent valuation and laboratory experiments on the demand to reduce externalities recent field experiments show that peer information can induce people to reduce their production of negative externalities related work in psychology demonstrates that inducing feelings of relative culpability in one domain can induce spillover pro social behavior in another domain we use a contingent valuation and parallel lab experiment to explore patterns of cross domain responses to norm based interventions asymmetric responses between those whose impacts are above or below the norm are found to be robust across decision settings substantial heterogeneity in responses is observed across a number of dimensions not explored in large field experiments raising questions about the universality of peer information effects and the design of such programs

intention of agricultural professionals toward biofuels in iran implications for energy security society and policy abstract this research applies the health beliefs model hbm as a framework for understanding the intentions of agricultural professionals with respect to biofuels we argue that it is essential to understand these intensions as agricultural professionals play critical role as educators gatekeepers and stakeholders in the agricultural domain a face to face survey was undertaken in south western iran using a multi stage stratified random sample of agriculture professionals n 288 the reliability and validity of the instruments were examined and approved structural equation modeling showed that general beliefs regarding fuels and biofuels perceived benefits perceived severity self efficacy and cue to action are significant predictors of professionals willingness to support biofuels these variables can predict nearly 43 variance in professionals willingness the findings yield public policy implications for biofuel use and development support among professionals and provide preliminary support for the hbm as an effective framework for examining intention toward biofuels among agriculture professionals in iran

determining factors of curtailment and purchasing energy related behaviours changing people s behaviour in relation to energy consumption will be one of the most important challenges in the near future we analyzed the determinants behind individuals decisions to adopt curtailment behaviour or to purchase energy saving products using data from 213 university students we explored the influence of personal capabilities and moral norms along with trust in information on energy saving actions provided by different entities on two energy saving behaviours the results of the statistical model emphasise how personal norms and trust in information provided by private companies on the one hand and family and friends on the other strongly influence the adoption of energy saving actions and curtailment behaviours the paper reveals the pivotal role of private companies in developing the market demand for energy saving products by providing credible and scientifically based information on environmental performance the paper also contributes to strengthening the reliability of value belief norm theory and emphasizes the role of trust in information as a contextual factor that influences the adoption of a pro environmental behaviour

consumer demand for green power and energy efficiency abstract this article examines reported willingness to pay for electric utility investments in renewable energy and energy efficiency resources using the results of deliberative polls conducted by electric utilities in texas 1 age education and salary tend to affect reported willingness to pay for utility investments in these resources intensive exposure to information about energy resource issues led to an increase in the number of respondents interested in paying a modest premium to support investments in both renewable energy resources and energy efficiency however average reported premiums actually declined following the polls as very high outlier responses moved to more reasonable values following the polls these results support the contention that informed dialogue about energy alternatives will result in broader interest in providing a modest level of support for these resources

optimal hedging and equilibrium in a dynamic futures market abstract this paper considers an agent maximizing the expected utility of the sum of the terminal value of a fixed portfolio of spot market assets and the terminal value of a margin account on a futures trading position closed form solutions for the optimal hedging strategy are provided in several special cases

preferences for green electricity investment and regulatory incentives abstract this paper develops a theoretical model to investigate how consumers preferences for green electricity affect the incentives of a regulated firm to provide and invest in electricity from green sources optimal incentive regulation implies a trade off between providing an optimal match of consumers with green and brown electricity and efficient incentives to invest in cost reductions we show that a single price cap on green electricity is ineffective as it yields the same expected market outcome as with an unregulated firm price caps on both green and brown electricity are akin to a market share target policy which implements efficient investment but gives an inefficient ex post consumer allocation a single price cap on brown electricity weakly dominates these schemes and gives rise to three different optimal regulation regimes as a function of the underlying technology parameters

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

renewables portfolio individual preferences and social values towards res technologies abstract the massive deployment of renewable energy sources represents a high priority for greece in order to comply with the directive 2009 28 ec on the promotion of the use of energy from renewable sources by 2020 in this perspective aegean islands especially lesvos are endowed with a considerable potential of a portfolio of renewables a fact that the entrepreneurial interest has already been targeted however regulatory attempts for a massive penetration of renewables do not take seriously into account preferences and risk perceptions of local communities where the proposed projects are to be installed the aim of this study is to investigate individual preferences and social values towards specific technologies of renewables in lesvos island we apply an open ended contingent valuation survey in order to analyze factors shaping public attitudes towards a portfolio of renewable technologies and estimate the economic welfare willingness to pay of the preferred technologies we argue that such information is relevant for energy policy design and the establishment of effective measures for the promotion of renewable energy sources

liberalising european electricity markets opportunities and risks for a sustainable power sector the process of liberalising european electricity markets encompassing a wide range of restructuring activities has mainly been spurred by the attempt to increase the economic efficiency of the whole sector this process might be used to trigger a development towards a sustainable power sector by increasing the use of renewable energy sources and enhancing energy efficiency on the supply and demand side however by taking a closer look at the current trends of the european electricity markets it becomes obvious that the liberalisation not only implies opportunities but also risks for the creation of a sustainable power sector many of these risks are due to market distortions and imperfections caused by the delay in creating a fully functional single european market thus in the short term the market liberalisation tends to constitute more risks than opportunities without government actions to prevent these risks in the long run though the efficiency gains of the sector and the appearance of new market factors are likely to bring forth the opportunities of liberalisation and actively foster a transformation towards a sustainable electricity sector

exploring the links between community based governance and sustainable energy use quantitative evidence from flanders community based energy organizations have been said to influence their members energy related behavior by activating social norms and by providing trustworthy information about sustainable energy investments and behaviors however little is known yet about members actual energy use and how it differs from that of individuals who do not participate in such projects in particular selection effects are likely to arise i e community based energy projects may attract people that are different from the underlying population in terms of energy use this article empirically addresses the question of the selection into community based energy projects in terms of energy use focusing on the case of renewable energy cooperatives based on quantitative data from an original survey conducted with one renewable energy cooperative in flanders and using probit regression analyses it contrasts a sample of cooperative members with an appropriate comparison group in terms of electricity usage the results show that electricity consumption is positively related with cooperative membership suggesting that high use consumers have greater incentives to join a community based organization which provides assistance and advice on the adoption of green technologies and energy efficiency measures these findings contribute to an understanding of the relationship between community based governance and sustainable energy practices

woodsy the optimal owl environmental campaigns norms and implications for public goods policy norms regarding private provision of a public good e g cutting down on energy use not littering can affect the marginal gains from contributing to a public good and therefore people s decisions about contributing to the public good a model is proposed in which norms of private contributions to a public good can be influenced by public policy and these norms affect people s self image which derives from a comparison of one s own contribution with the norm contribution in this context we examine the conditions under which private contributions to a public good are efficient and the conditions under which policy affecting these norms improves social welfare we find that 1 a benevolent social planner who fails to account for private provision norms will underprovide the public good and 2 public policy that attempts to raise the norm contribution of private provision can increase social welfare if the effect of raising the norm does not have an extreme negative effect either extremely small or extremely large on peoples self image

consumers willingness to pay for green electricity a meta analysis of the literature at present electricity generated from power plants using renewable sources costs more than electricity generated from power plants using conventional fuels consumers bear these expenses directly or indirectly through higher prices for renewable energy or taxes the number of studies published over the last few years focusing on people s preferences for renewables has increased steadily making it more and more difficult to identify key explanatory factors that determine people s willingness to pay wtp for renewables we present results of a meta regression on valuation of consumer preferences for a larger share of renewable energy in their electricity mix our meta regression results reveal a number of important factors that explain the differences in wtp values for renewable energy different valuation methods show widely different values with choice experiments producing the highest estimates our results further indicate that consumers wtp for green electricity differs by source with hydropower being the least valued variables that are often omitted from primary valuation studies are important in explaining differences in values these variables describe individual and household characteristics as well as information on the type of power plant that will be replaced by renewables further the marginal effect of a survey conducted in the us is pronounced we also assess the potential for using the results for out of sample value transfer and find a median error of 21 c 2015 elsevier b v all rights reserved

residential bioenergy heating a study of consumer perceptions of improved woodstoves abstract consumers choices play a key role for the development of biomass heating in the residential sector the city of oslo has granted subsidies to households who change to new improved low emission woodstoves the purpose of this study is to expand the knowledge about users experiences and attitudes to residential biomass heating an adapted model of the theory of planned behavior was used to model households inclination to continue using their woodstoves for heating more than 800 questionnaires were collected from households that recently had invested in an improved woodstove the respondents were satisfied with the new woodstoves the respondents also considered themselves competent to use and maintain the stove and few had problems acquiring fuelwood further analyses showed that the intention to continue to use the new woodstove depends on economic benefits heating performance perceived time and effort to operate the stove environmental effects of heating as well as perceived subjective norm the results imply that when marketing a modern technology for bioenergy heating both public authorities and producers should consider issues related to the users perception of subjective norm such as perceived status of using bioenergy or environmental concerns when designing campaigns to promote the use of woodstoves

do contingent valuation estimates pass a scope test a meta analysis abstract this paper considers the scope test proposed to judge the internal consistency of contingent valuation estimates the test is shown to be quite sensitive to the maintained hypotheses required to derive fairly precise expectations for the properties of wtp functions and therefore a different approach may be needed in gauging the reliability of cv this paper describes an approach that relies on a weight of the evidence criterion and uses meta analysis to develop a systematic appraisal of what the economic values of changes in amenity resources are the approach is illustrated for the case of estimating people s willingness to pay for improving or maintaining visibility at the national parks

environmental damage evaluation in a willingness to accept scenario a latent class approach based on familiarity in this paper we report on the results of the application of a latent class model that was designed to identify and characterize unobserved preference heterogeneity in the context of a willingness to accept wta framework involving negative environmental externalities stemming from the expansion of the port of valencia we investigated the hypothesis that respondents with greater familiarity with the targeted good and any related environmental damage would demand more compensation that is they would have a significantly higher wta based on respondents familiarity with the port of valencia and their pre existing knowledge about the negative consequences of its potential expansion three clusters based on six indicators are identified results show that contrary to what might be expected familiarity with a public good does not in all cases have a significant effect on stated wta

does environmental concern change the tragedy of the commons factors affecting energy saving behaviors and electricity usage electricity consumption produces private goods such as heat for homes but fossil fuel consumption impacts the public goods of clean air and water while self interests can increase usage social interests such as global climate change can impact an individual s attitude toward energy consumption this paper examines the tragedy of the commons using household data and compares the impact of self and social interests in predicting electricity consumption using both stated and observed behavioral data the results show that self interests have a greater impact on energy saving behaviors and electricity use we extend the analysis to control for an individual s environmental concern and perceived behavioral impact finding similar results and supporting the notion that the tragedy of the commons occurs regardless of a person s perception or environmental concern these findings may explain why pro environmental attitudes do not necessarily lead to pro environmental behaviors and it contributes to our understanding of the motivating factors for energy savings and electricity use by examining both stated and observed behaviors policies aimed at electricity reduction may have a greater impact if they focus on private interests such as pricing rebates subsidies and taxes rather than social interests alone

minimizing cvar and var for a portfolio of derivatives value at risk var and conditional value at risk cvar are the most frequently used risk measures in current risk management practice as an alternative to var cvar is attractive since it is a coherent risk measure we analyze the problem of computing the optimal var and cvar portfolios in particular we illustrate that var and cvar minimization problems for derivatives portfolios are typically ill posed for example the var and cvar minimizations based on delta gamma approximations of the derivative values typically have an infinite number of solutions in this paper we focus on the portfolio selection problem which yields a portfolio of the minimum cvar with a specified rate of return we propose to include cost as an additional preference criterion for the cvar optimiza tion problem we demonstrate that with the addition of a proportional cost it is possible to compute an optimal cvar derivative investment portfolio with significantly fewer instru ments and comparable cvar and var a computational method based on a smoothing technique is proposed to solve a simulation based cvar optimization problem efficiently comparison is made with the linear programming approach for solving the simulation based cvar optimization problem

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

wind farm externalities and public preferences for community consultation in ireland a discrete choice experiments approach abstract in ireland the deployment of onshore wind turbines has become progressively more difficult in some areas because of the potential negative externalities associated with their operation using a discrete choice experiment dce we employ a willingness to accept framework to estimate the external effects of wind turbines on local residents with the inclusion of community consultation and to quantify the compensation required to permit wind farms to be built in ireland our findings reveal that the majority of respondents are willing to make monetary tradeoffs to allow for wind power initiatives and we find that respondents require less compensation if provision is made for a community representative and setback distance is increased

does education increase pro environmental behavior evidence from europe abstract it is often observed that individuals with higher education levels tend to be more environmentally friendly yet the causal evidence is lacking because there may well be omitted variables that cause individuals to attain more education and also cause individuals to be environmentally conscious we implement a regression discontinuity design to estimate the increase in educational attainment due to changes in compulsory education laws in 20th century europe this allows us to overcome the identification problem of endogenous educational attainment using two waves of eurobarometer surveys we find a positive local average treatment effect for 7 of the 8 pro environmental behaviors an analysis of related questions on the survey supports the notion that education causes individuals to be more concerned with social welfare and to accordingly behave in a more environmentally friendly manner

wind farms where and how to place them a choice experiment approach to measure consumer preferences for characteristics of wind farm establishments in sweden this paper explores preferences among the general public in sweden for attributes related to the establishment of wind power farms the method applied is a choice experiment where people are asked to choose between two hypothetical wind farms characterized by different attributes five attributes are included in the experiment i type of landscape ii type of ownership iii the degree of local participation in the planning process iv the choice to transfer revenue to the society in a pre specified way and v a monetary cost in terms of an additional electricity certificate fee the data are analyzed with multinomial logit random parameter logit and latent class models the results indicate that consumers in sweden are more likely to accept the higher renewable electricity certificate fee if a wind power farms in areas used for recreational purposes are substantially avoided b the establishment is anchored by whole or partial ownership in the local community and c the locals are involved in the planning and implementation process our policy simulation exercise shows that respondents are willing to pay a higher electricity fee corresponding to about 0 6 euro cents per kwh to avoid wind farms located in the mountainous area and private ownership

norms and economic motivation in the swedish green electricity market abstract the purpose of this paper is to provide an econometric analysis of the most important determinants of swedish households choice to pay a price premium for green electricity we draw on recent developments in the literature on integrating norm motivated behavior into neoclassical consumer theory and assume that individuals have a preference for keeping a self image as a morally responsible person consumer behavior in the green market place will then be heavily determined by how purchases of different goods affect this self image the analysis is based on postal survey responses from 655 swedish households which are analyzed within a binary choice econometric framework the results indicate that the impact of choosing green on the household budget largely influences the choice between green and brown electricity as does the degree of perceived personal responsibility for the issue and the felt ability to affect the outcome in a positive way we find limited support for the notion that perceptions about others behavior in general affect individual moral norms and ultimately expressed behavior but this is also complemented by the influence of explicit social influence the difficulty in observing others purchases makes it however difficult to distinguish between social and moral norms in the case of green electricity

warm glow from green power evidence from australian electricity consumers abstract green electricity products are increasingly made available to consumers in many countries in order to address a number of environmental and social concerns most of the literature on this green electricity market focuses on consumers characteristics and product attributes that could affect participation however the contribution of this environmental consumerism to the overall environmental good does not depend on participation alone the real impact relies on market participation for green consumers the proportion of green consumers combined with the level of green consumption intensity the commitment levels or proportion of consumption that is green we design an online interface that closely mimics the real market decision environment for electricity consumers in western australia and use an error component model to analyze consumers choice of green electricity products and their commitment levels we show that product attributes have limited impact on the choice of green products however there is still great potential for better participation by improving the design of green electricity programs when green products are selected most respondents select the minimum commitment possible and this is insensitive to the premium being charged on green power suggesting that we are largely observing a buy in warm glow for carbon mitigation

the united kingdom demand for renewable electricity in a liberalised market abstract this paper analyses how the liberalisation of the uk electricity market in 1998 may encourage demand for renewable electricity through pricing and informational incentives the analysis argues that prices and beliefs will be crucial for influencing customers willingness to pay for environmental costs associated with electricity generation as well as their decision to not just buy the cheapest electricity in 1998 when uk electricity markets are liberated a small price differential between renewable and standard electricity certainly less than 20 and clear credible and captivating information about the external costs of electricity generation could create a considerable demand for renewable electricity but because renewable generating capacity will initially be small and slow to adjust to incentives initially high demand may drive up prices discouraging customers from wanting to buy renewable electricity low demand on the other hand will not provide the incentives to invest new capacity which probably means that renewable technology will not be able to reduce its unit costs of electricity generation and compete in a liberalised market without continued financial support to avoid either scenario this paper recommends that government should extend the non fossil fuel obligation nffo to promote investment in renewable technology provide tax incentives to minimise the price differential between renewable and standard electricity encouarge non governmental organisations to develop schemes for providing customers with clear consistent and reliable information about sources of renewable electricity and stagger the introduction of electricity liberalisation while the analysis is of a speculative nature such policies may create incentives for markets to reduce environmental damage associated with electricity generation

using contingent valuation to explore willingness to pay for renewable energy a comparison of collective and voluntary payment vehicles abstract this study uses a split sample dichotomous choice contingent valuation survey of 1574 u s residents to explore willingness to pay wtp for renewable energy under collective and voluntary payment vehicles and under government and private provision of the good we also evaluate the impact of participation expectations on stated wtp we find some evidence that when confronted with a collective payment mechanism respondents state a somewhat higher wtp than when voluntary payment mechanisms are used similarly private provision of the good elicits a somewhat higher wtp than does government provision we also find that contingent valuation responses are strongly correlated with expectations for the wtp of others our results shed light on strategic response behavior and the incentive compatibility of different cv designs and offer practical insight into u s household preferences for how to support renewable energy

feeding and fueling china in the 21st century abstract this paper addresses the questions to what extent will china become a significant net importer of food and fuel in the foreseeable future and what will be the impact of that import demand growth on international markets it first summarizes what standard trade and development economics and the experiences of other asian economies suggest we should expect of china and then examines china s experience to date before turning to some forecasts for the next decade or so our review suggests that before long china will become a significant net importer of both food and fuels especially petroleum contrary to chinese fears however becoming more interdependent with the rest of the world need not be threatening and it may even offer more supply security for china in the long run

electricity restructuring greenhouse gas emissions efficiency and employment reallocation abstract this paper focuses on demonstrating the feedback relationships between greenhouse gas emissions efficiency in the electricity sector and employment reallocation with a consideration of the effects of electricity restructuring and socio demographic factors we postulate the construction information manufacturing utilities and mining sectors as a group of emissions efficiency related industries and identify the mutual relationships the emissions efficiency positively influences the job shares of these industries except mining whereas increased employment in these industries has a negative effect on the emissions efficiency electricity restructuring has a positive effect on overall employment however it does not have a statistically significant effect on the emissions efficiency additionally population aging and educational attainment have positive effects on the emissions efficiency and a higher proportion of rental households has a negative influence on it increases in renewable energy and nuclear energy generation have elastic effects on enhancing emissions efficiency

can renewable energy be financed with higher electricity prices evidence from a spanish region abstract in this paper we estimate the willingness to pay for mix of renewable sources of electric power by means of a discrete choice experiment survey conducted in spain in 2010 two main categories of power supply attributes are explored source of renewable power wind solar and biomass and the origin of such power the findings suggest that most consumers are not willing to pay a premium for increases in the shares of renewable in their electricity mix for two of the three renewable sources considered wind and biomass an increase of the renewable mix would require a discount instead we record positive willing to pay for increases in the share of both solar power and locally generated power however preferences for types of renewable solar and wind are found to be heterogeneous by classifying respondents in two groups according to the implied importance of the share of renewable sources in their power mix we identify a market segment consisting of 20 of respondents that could promote renewable energy in the absence of subsidies this is because such a segment shows willingness to pay higher than the current feed in tariffs

what are retail investors risk return preferences towards renewable energy projects a choice experiment in germany citizens own nearly half the renewable energy generation capacity in germany and have been important drivers of the country s energy transition in contrast to citizens important role in financing renewable energies the energy policy and economics literature has traditionally focused on other investors such as incumbent energy firms to close this gap this paper reports on a large scale survey of 1 990 german retail investors conducting a choice experiment with the subset of 1 041 respondents who expressed an interest in investing in community renewable energy projects we present a unique dataset allowing for new insights in risk return expectations of retail investors we find that apart from return on investment respondents are particularly sensitive to the minimum holding period and the issuer of community renewable energy investment offerings a minimum holding period of 10 years implies a risk premium of 2 76 points a subsequent segmentation analysis shows that two groups of potential community renewable energy investors with different risk return expectations can be identified local patriots and yield investors in contrast to professional investors a majority of retail investors use simple decision rules such as calculating payback time or relying on their gut feeling when making investments

environmental awareness consumption and labor supply empirical evidence from household survey data abstract what is the effect of environmental awareness on the households consumption of polluting goods and labor supply decisions we answer this question using household survey data from the united states and measuring environmental awareness with the decision to make environmental donations we find that environmental awareness has a negative and economically significant effect on labor supply the respective impact on the consumption of polluting goods is also negative but less robust in terms of statistical significance our results highlight the importance of understanding the foundations of household behavior related to environmental quality indeed environmentally aware households are willing to tradeoff work hours with improved environmental quality and less so to change their consumption habits

growth in china s grain production 1978 1997 a disaggregate analysis abstract this paper analyzes china s grain production during 1978 97 using disaggregate approach to explore disparities in growth patterns of respective crops the study reveals that during this period almost all the increased output can be attributed to the growth of rice wheat and corn the contribution of other crops as a whole was almost negligible the disparities in growth patterns were partly the result of crop adjustments induced by changes in food demand and dominated by substitutions of high yield crops for low yield crops in this process the adoption of new technologies played an important role varying opportunity costs of grain production in different areas also affected growth patterns of respective crops the trend in china s grain production in the past two decades suggests that the adherence to grain self sufficiency has become not only increasingly costly but also unnecessary

managing risk in multi asset class multimarket central counterparties the core approach abstract multi asset class multimarket central counterparties ccps are becoming less uncommon as a result of merges between specialized single asset class single market ccps and market demands for greater capital efficiency yet traditional ccp risk management models often lack the necessary sophistication to estimate potential losses relative to the closeout process of a defaulter s portfolio in a multi asset class multimarket environment as a result multi asset class multimarket ccps usually rely on a simplified silo approach for risk calculation which not only fails to deliver efficiency but may also increase systemic risk the core closeout risk evaluation approach on the other hand provides conceptual and mathematical tools necessary for robust and efficient central counterparty risk evaluation in multi asset class and multimarket environments acknowledging the portfolio dynamics involved in the closeout process as well as important real life market frictions

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

how should china feed itself since the publication of brown s book enormous interest in the issue has been generated among policymakers and scholars around the world this surge in interest coincided with the sharp rises in world food prices in the year to june 1996 following on from harvest shortfalls in several grain producing regions around the world with the slowing of grain output growth since the mid 1980s chinese policymakers have been particularly concerned about food security brown s dire prediction has aggravated their concern

too poor to be green consumers a field experiment on revealed preferences for firewood in rural guatemala the paper reports on a field experiment that investigates whether households in guatemala are willing to surrender a small material gain in order to buy legal rather than illegal firewood given the ineffectiveness of command and control policies to curb the problem of illegal logging in guatemala the experiment assesses the potential viability of market oriented solutions local consumers in developing countries are generally believed to be too poor to pay a premium for green ethical products therefore little information has been gathered on willingness to pay wtp for such products and its determinants in non affluent consumer markets while our experiment on firewood consumption in central guatemala only implies a weak and indirect test of wtp for green products the results indicate that it is premature if not unwarranted to assume that the poor are not ready to make pro ethical choices in the marketplace moreover we find that information on the legal procedures for firewood extraction significantly affects consumer choice between legal and illegal firewood

are french consumers ready to pay a premium for eco labeled seafood products a contingent valuation estimation with heterogeneous anchoring could the future french eco label for fresh seafood products find its place in the french market this study employs a contingent valuation method to estimate french consumers willingness to pay wtp for eco labeled fresh seafood products we exploit original data from a survey carried out in 2010 where 626 participants responded to a double bounded dichotomous choice model through an ascending or descending bid system controlling for shift and anchoring effects in random effect probit models we significantly improve estimation of wtp and its determinants for the three species studied monkfish lobster sole in particular when using heterogeneous anchoring we show that wtp is positively correlated to respondents income and also to their environmental concern to living alone to living far from the coast and to trusting ngos or public institutions more than producer organizations to implement an eco label we also show that the mean price premiums do not differ between species finally on average the maximum premium consumers accepted to pay is approximately 10 of the product price

heterogeneous preferences and the individual change to alternative electricity contracts abstract based on data from a large scale computer based survey among more than 3700 citizens in germany this paper empirically disentangles the determinants of the general change of electricity contracts and the specific change from any green or non green to current green electricity contracts within the last ten years our econometric analysis reveals a strong relevance of behavioral factors and individual values and norms for example patience which was measured by an incentivized experiment included in the survey has a significantly positive effect on both general switches to alternative electricity contracts and specific switches to green electricity contracts furthermore trust and less robust social preferences also measured by an incentivized experiment have additional significantly positive effects on the specific change to green electricity contracts our estimation results also imply an important role of political identification i e an ecological policy orientation is strongly significantly positively correlated with the change to green electricity contracts furthermore several household specific factors like relocation decisions as well as socio demographic and socio economic variables like household income are also relevant the empirical analysis thus provides new explanation patterns for the phenomenon that relatively few households regularly change their electricity contracts and specifically switch to green electricity contracts although they have high stated preferences for such changes our insights suggest several directions for policy and electricity suppliers to increase these switching rates for example the high importance of trust for the change to green electricity contracts suggests transparency initiatives of electricity suppliers to decrease concerns against renewable energies

one without the other behavioural and incentive policies for household waste management this paper provides a review of economic studies that analyses the use of multiple policies to cope with waste management problems we discuss the factors that influence selective sorting behaviour and the most appropriate policies for their promotion based on the works analysed our survey shows the original features of waste as an environmental problem requiring regulation the traditional approach in which decisions respond to rational behaviour particularly cost savings has some limits although not all public policies seem justified we argue that there might be a need for specific policies to promote recycling preferably based on the provision of information to consumers or on behavioural instruments indeed personal factors specific to each individual such as emotions and the influence of social interaction should be taken into account in the development of public policies we review the literature related to different rationales and identify some avenues for future research

a review of international green power markets recent experience trends and market drivers green power marketing the act of differentially selling electricity generated wholly or in part from renewable sources has emerged in more than a dozen countries around the world almost two million customers worldwide buy green power today this paper reviews green power marketing activity in australia canada japan the us and in a number of countries in europe to gain an understanding of consumer demand for electricity generated from renewable sources it also examines key factors that influence market penetration of green power products such as product designs pricing incentives marketing strategies policies and product certification 2002 elsevier science ltd all rights reserved

stuck between a roc and a hard place barriers to the take up of green energy in the uk abstract 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

keep it local and fish friendly social acceptance of hydropower projects in switzerland hydropower is the largest source of renewable electricity in the world but despite being a mature and clean energy technology it has also been the subject of ecological and social conflict literature suggests that the social acceptance of renewable energy can be increased by respecting procedural justice fair participatory planning processes and distributional justice fairly allocating costs and benefits however empirical evidence about how justice considerations are related to the expansion of hydropower is scarce pre existing studies being mostly qualitative in nature we contribute to filling the gap in the current literature by describing in this paper how choice experiments with 1004 swiss residents were undertaken to explore the influence of procedural and distributional justice on acceptance relative to other attributes of hydropower projects we find that while considerations about justice do play a role in decisions to accept respondents in switzerland care most about ecological impacts and secondly about local ownership

the influences of financial and non financial factors on energy saving behaviour a field experiment in japan abstract this study examines the influences of financial and non financial factors on electricity conservation behaviour a random sample of 236 japanese households participated in the field experiment and the participants were offered two interventions such as monetary rewards depending on their reduction in electricity consumption and comparative feedback the average saving rates of the i reward intervention group 5 9 and the ii reward with comparative feedback group 8 2 are statistically larger than those of the iii control group 1 7 our study demonstrates the following first our econometric analysis confirmed a significant response by households to financial incentives but a more inconclusive response to the treatment that provided non financial additional information second we found a positive influence of treatment externalities across time and households on energy saving third there is a heterogeneous treatment effect in the reward intervention group with the households having a high new ecological paradigm nep score being more likely to respond to the reward programme and save electricity than those that do not finally and most interestingly differences in responses to the questionnaire before and after the experiment suggest that the participants had underestimated the marginal costs of saving electricity before they actually started to do so

applying threshold models to donations to a green electricity fund this study applies a threshold model proposed by granovetter 1978 to analyze the diffusion process of donating behavior for renewable energy we first use a stated preference survey to estimate the determinants of a decision to support the donation scheme under various predicted participation rates using the estimated coefficients we simulate how herd behavior spreads and the participation rate reaches the equilibrium the participation rate at the equilibrium is estimated as 37 88 when the suggested donation is 500 yen while it is 17 76 when the suggested amount is 1000 yen the influence of environmentalism and altruism is also examined and we find that these motivations increase the participation rate by 31 51 on average

consumer preferences for electricity tariffs does proximity matter abstract the introduction of renewable energy sources fosters the transformation to an energy system with distributed generation this alters the relation between consumers and power generation sites as generation and consumption spatially converge it allows for new configurations within the energy sector and provides opportunities for marketing regional energy we empirically investigate consumer preferences for electricity generation in proximity to end users focusing on the proximity of generation and providers and present representative data for germany in a discrete choice experiment a sample of 780 consumer households and 173 adopters of a renewable energy system prosumers chose from a range of different electricity tariffs we estimate the willingness to pay for the following attributes shares of regional generation power providers and electricity mixes we find evidence in favor of regional production but in spite of positive attitudes towards local generation from renewable sources willingness to pay is not responsive to higher shares of regional generation in addition a preference for regional providers exists the results show that renewable energy mixes are preferred particularly a solar and hydro mix adopters state slightly more distinct preferences as compared to consumer households thus we find there is potential for business models offering regionally generated electricity

trade policy biotechnology and grain self sufficiency in china abstract over the past 20 years the growth of china s agricultural economy has been extraordinary however it seems unlikely that china will maintain self sufficiency in grains by 2005 without substantial intervention we develop a cge model to assess the options available to chinese policy makers we compare the welfare effects of import tariffs and domestic support and explore the potential of biotechnology as a means to achieve self sufficiency through improvements in agricultural productivity our results indicate that the price interventions that would be required to maintain china s desired self sufficiency ratios are considerable and are unlikely to be compatible with wto accession the productivity improvements required are also significant and likely beyond the current potential of biotechnology

risk management strategies via minimax portfolio optimization recent extreme economic developments nearing a worst case scenario motivate further examination of minimax linear programming approaches for portfolio optimization risk measured as the worst case return is employed and a portfolio from maximizing returns subject to a risk threshold is constructed minimax model properties are developed and parametric analysis of the risk threshold connects this model to expected value along a continuum revealing an efficient frontier segmenting investors by risk preference divergence of minimax model results from expected value is quantified and a set of possible prior distributions expressing a degree of knightian uncertainty corresponding to risk preference determined the minimax model will maximize return with respect to one of these prior distributions providing valuable insight regarding an investor s risk attitude and decision behavior linear programming models for financial firms to assist individual investors to hedge against losses by buying insurance and a model for designing variable annuities are proposed

determinants of demand for green products an application to eco label demand for fish in europe abstract in this paper we confront the theoretical motivations of the consumption of eco friendly products and the factors influencing the european perceptions regarding the fact that fish caught using an environmentally friendly technique may carry a special label we take advantage of the recent integration of non economic elements in the microeconomic analysis of consumers behavior in order to highlight the factors leading to their demand for green products thanks to an original european survey on seafood product carried out on more than 5000 consumers we test the influence of intrinsic motivation information localization and socio economic factors on the demand for an eco label for fish our results show a significant connection between the desire for eco labeling and seafood features especially the freshness of the fish the geographical origin of the fish and the wild vs farmed origin of the fish moreover we prove the major role played by the fish price we also demonstrate that the ecological issue regarding fisheries is highly connected to consumer information intrinsic motivation and socio economic status the typical green fish consumer is a young woman well educated well informed on the state of marine resources and not very trusting of the regulation of the fisheries consumers who are aware of the importance of marine resource preservation have the same profile

consumer price and promotion expectations an experimental study the authors report results from a controlled experiment designed to investigate the impact of a brand s price promotion frequency and the depth of promotional price discounts on the price consumers

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 structure of motivation for contingent values a case study of lake water quality improvement abstract critics of the contingent valuation cv method have argued that individuals apply noneconomic motives in responding to cv questions implying that elicited values are not valid measures of the economic benefit of environmental improvement this study examines the role of such motives by using measures of attitude and motive strength to interpret willingness to pay wtp values for a set of nested environmental goods with potential use and nonuse benefits motivational structure is found to be more complex than suggested by the simple distinction between valid economic theoretic and noneconomic motives social motivations possibly associated with the benefit of contributing to a public good rather than the benefits of the good itself are potentially relevant to the wtp decision but do not give rise to separable values the strength of perceived personal responsibility for provision of the good is significantly associated with wtp but also with the theoretically desirable property of enhanced scope sensitivity wtp is not found to be associated with the extent to which the individual feels under some general moral obligation to contribute to good causes motives arising from ethical concerns for the environment and altruism are also potentially relevant to wtp but are closely related to underlying motives associated with existence and personal use values respectively it is suggested that the cv debate should be informed by further empirical investigation of the extent to which motives for wtp can be treated as separable

price volatility and residential electricity decisions experimental evidence on the convergence of energy generating source abstract the recent trend in most developed countries has been toward greater reliance on renewable or green energy sources this paper investigates how price volatility in residential electricity rates impacts consumers preferences for green power using a choice based experiment we present respondents with choice scenarios that feature two electric utility plans i a conventional plan where electricity is generated from either coal or natural gas and ii a green plan where electricity is generated renewably from either wind or solar we then systematically vary the monthly price volatility of each plan across choice scenarios our results suggest that price volatility in monthly rates significantly impacts respondents plan choices and specifically their decision to adopt the green power plan in particular increased volatility in the green power plan reduces the likelihood of respondents choosing the green plan while increased volatility in the conventional plan increases the likelihood of respondents choosing the green plan moreover the documented effects of price volatility are robust across different price premiums for the green power plan

willingness to pay for green power in an unreliable electricity sector part 1 the case of the lebanese residential sector abstract a willingness to pay wtp analysis for renewable based electricity is undertaken for the lebanese residential sector a survey of 600 samples was conducted based on a stratified random sampling method in which energy use and expenditures socioeconomic and demographic characteristics were collected four scenarios for wtp for green power were designed to best reflect the possibilities of integrating renewable energy re sources in lebanon s unreliable electricity sector 1 local system covering partial electricity needs 2 local system covering entire electricity needs 3 utility provided green power covering partial electricity needs and 4 utility provided green power covering entire electricity needs the results based on a tobit model highlight the importance of re options that displace completely the diesel generator sets i e options 2 and 4 other parameters such as ownership of the home age perception of trust in government institutions and awareness of re were also found significant in influencing wtp

environmental labelling of electricity delivery contracts in sweden abstract competition in the electricity market allows customers to choose between suppliers as a consequence customers may demand electricity from specified sources of energy in sweden the swedish society for nature conservation ssnc operates a system of environmental labelling of electricity delivery contracts since 1996 labelling is available for suppliers offering electricity from renewable sources of energy with some additional criteria companies may acquire a licence to use the label by showing ability to deliver such electricity and by agreeing to be audited the system is private independent it is operating on the bases of credibility earned by the ssnc during 90 years as an environmental organisation and 10 years as operator of environmental labelling of consumer products the system is market oriented compatible with wto and eu market principles and independent of governmental environmental restrictions subsidy or quota systems it is relying on voluntary agreements the results are desirable if only a few by electricity under labelled contracts as well as if every customer do so the market is growing a majority of the suppliers have a license and may offer labelled contracts in the year 2000 7 of all electricity sold to final consumers was sold under labelled contracts

the devil is in the details household electricity saving behavior and the role of information abstract the purpose of this paper is to analyze swedish households willingness to increase their daily efforts to save electricity the analysis builds on a broad theoretical framework which embraces both economic and norm based motivations in explaining household behavior the paper pays particular attention to the role of information about the availability of different behavioral changes that can be undertaken at the household level the empirical results are based on a postal survey that was sent out to 1200 swedish households and the econometric analysis is carried out within a so called ordered probit framework our results indicate that costs environmental attitudes and social interactions are all important determinants of electricity saving activities within swedish households we tested the hypothesis that information about available savings measures that is presented in a more concrete and specific way is more likely to affect stated behavior than is more general information and the data collected support this notion the paper ends by discussing some implications of these results for the design of future informative policy measures in the energy efficiency field

investment preferences for wood based energy initiatives in the us abstract the forest sector is poised to become a major supplier of wood based energy in the us prospects for growth in energy demand and higher prices can create opportunities for private investments in renewable energy industries a conjoint analysis examined individuals willingness to invest in wood based energies following a random utility model the study design included three investment attributes annual returns on investment type of investment and location of investment three ordinal models that also included demographic and attitudinal characteristics indicate that wood based energy is less preferred among potential investors compared to the stock market and solar wind renewable energy investments expected returns and location of energy investments within the us are also major drivers of investment preferences favorable attitudes towards forestry and wood based energy could enhance prospects for a greater number of potential investors

social acceptance of renewable energy sources a review of contingent valuation applications abstract this paper presents a literature review addressing the public acceptance of renewable energy as a replacement for fossil fuels in electricity production this review was motivated by the global tendency for a substitution of conventional fuels by renewable energy sources res during the global financial crisis it studies research on the preferences and attitudes of local communities towards investments in renewable energy projects and their perception of the use of new energy technologies in their daily lives through various case studies worldwide an effort is made to identify the parameters that influence consumers energy behaviour together with their interest or lack thereof in the environmental impact of using fossil fuels to produce energy and their willingness to reduce it applications of contingent valuation are examined which are employed to analyse public attitudes towards the use of res for electricity production willingness to pay is observed to be correlated to socioeconomic characteristics including education interest in environmental issues and knowledge of res finally the profile of a typical green energy consumer and appropriate policy paths for the penetration of res into the energy market are outlined

valuing climate protection through willingness to pay for biomass ethanol abstract this study uses a multi part split sample contingent valuation method cvm and fair share fs survey to better understand the public s valuation of mitigating global climate change through its willingness to pay for biomass or cellulosic ethanol in addition to a basic cvm question a related scenario was developed that asked half of the survey respondents to state their fair share cost to lessen a potential food shortage in the next decade also through the expanded use of cellulosic ethanol three alternative biomass feedstocks were assessed farming residues forestry residues and paper mill wastes and municipal solid wastes overall a slightly larger proportion of respondents were wtp extra for cellulosic ethanol in the basic cvm scenario than in the fs scenario though no significant differences were found in the wtp for the different feedstocks bid curve lognormal regression results for the two models were similar supporting the idea that asking a fs rather than a conventional wtp question may be justifiable in some circumstances such as in cases of a national emergency

whatever the customer wants the customer gets exploring the gap between consumer preferences and default electricity products in germany abstract in liberalized electricity markets residential customers can choose their preferred provider and select among a variety of different electricity products including green power options successful product design and marketing strategies for green electricity may provide electricity providers with a competitive advantage while at the same time contributing to energy policy objectives this requires however a thorough understanding of customer preferences we investigate the relative importance of different product attributes in creating customer value and find that price and electricity mix are the two most important attributes the german electricity customers we surveyed in 2009 expressed an implicit willingness to pay a premium of about 16 for electricity from renewable sources we conclude that consumers are willing to pay a significant price premium for an upgrade from the current default electricity mix in germany to a more environmentally friendly default electricity mix and discuss implications for marketing strategy and energy policy our findings are based on a dataset of 4968 experimental choices made by 414 german residential consumers collected in a stated preference survey

diffusion of renewable heating technologies in households experiences from the norwegian household subsidy programme abstract a sample of 896 norwegian households participating in a subsidy programme was surveyed in order to evaluate the success of the programme the programme subsidised investments in new heating technologies including heat pumps and pellet stoves the success of the programme was measured by the degree of overall satisfaction with the investment by the sampled households theories on diffusion of innovations and planned behaviour motivate the empirical modelling of the investment satisfaction the economic return on the investment varied substantially both within and between the two heating technologies with heat pumps outperforming pellet stoves in this respect still the economic return showed no explanatory power toward the investment satisfaction of the household among the economic variables only the electricity price had any influence on investment satisfaction technical quality indoor climate and heat comfort and the availability of the supplier of the heating equipment were the most important explanatory variables

eliciting public preference for nuclear energy against the backdrop of global warming one of the most important issues related to sustainability is to reduce the use of fossil fuels due to the reduction in greenhouse gases ghg emission nuclear power results in low carbon emissions and is thus important to mitigating the adverse effects of global warming and climate change however the downside of nuclear power cannot be overlooked and consequently nuclear power is a controversial issue in many countries around the world thus an important question concerns how people should support nuclear power do the climate and energy security benefits of nuclear power outweigh its risks and costs therefore we use a modified double bounded contingent valuation model to explore the attitudes and the willingness to pay wtp of a country in order to demonstrate its implications for policy we confirm that supporters and opponents of nuclear power are balanced both in terms of their numbers and in terms of their wtp the policy implication is that people do not support any dramatic increase or reduction in nuclear power and that nuclear power should still be an important means of generating electricity in taiwan the current share of nuclear power in electricity generation of 20 should be maintained in the near future

determinants of green electricity tariff uptake in the uk a number of countries offer domestic consumers the option of buying their electricity supply through a green tariff whereby the supplier typically guarantees that all or part of the supply has been generated using renewable energy sources previous studies that have sought to identify variables predicting why consumers choose to purchase a green tariff have utilized surveys specifically about the topic this study builds on previous work by reviewing the uk market using data from the understanding society survey a general survey of households which should be free from framing or focalism concerns in addition this data includes variables that to the authors knowledge have not been tested through other work results find that individuals in the highest income quartile those with higher qualifications those supporting the green political party and those exhibiting strong environmental behaviour were all more likely to have purchased green tariffs significant to a lesser degree were strong environmental attitudes and those households with some form of renewable energy technology installed

determinants of the price premium for green energy evidence from an oecd cross section using data from a survey of households in 11 oecd countries this paper investigates the determinants of preferences for a completely green residential electricity system three important questions are addressed i how much are households willing to pay to use only renewable energy ii does willingness to pay wtp vary significantly across household groups and countries and iii what drives the decision to enter the hypothetical market for green energy and given entry what drives the level of wtp the analysis here differs from previous studies on green energy in two ways first data and analyses are comparable across countries and second a comprehensive attempt is made to understand 0 wtp and to accommodate using a censored quantile regression cqr framework unobserved heterogeneity the survey data indicate a low wtp at 11 12 of current electric bill this study also addresses a key question how important is income for understanding wtp relative to more attitudinal determinants the effect of income overall appears ambiguous with tobit like models indicating that income is not significant while the cqr indicates that income exerts a significant effect near the center of the distribution of wtp across all frameworks used a key determinant of wtp appears to be environmental attitudes particularly membership in an environmental organization

information bias in contingent valuation effects of personal relevance quality of information and motivational orientation abstract a laboratory experiment examined the potential for information bias in contingent valuation cv consistent with the view that information about a public or private good can function as a persuasive communication willingness to pay wtp was found to increase with the quality of arguments used to describe the good especially under conditions of high personal relevance under low personal relevance wtp for a public but not for a private good was higher when an altruistic as opposed to an individualistic orientation was activated it is concluded that the nature of the information provided in cv surveys can profoundly affect wtp estimates and that subtle contextual cues can seriously bias these estimates under conditions of low personal relevance

what makes people seal the green power deal customer segmentation based on choice experiment in germany abstract consumers have the power to contribute to creating a more sustainable future by subscribing to green electricity tariffs in order to reach consumers beyond the eco niche identifying the drivers that positively influence the adoption of green electricity is of fundamental importance this paper examines various factors that help to explain the extent to which green electricity subscribers differ from those that display strong preferences towards green electricity but have not yet walked the talk by making use of a latent class segmentation analysis based on choice based conjoint data this paper identifies three groups of potential green electricity adopters with varying degrees of preference for renewable energy findings indicate that socio demographic factors play a marginal role in explaining the differences between green electricity subscribers and potential adopters with the exception that actual adopters tend to be better educated analysis of psychographic and behavioral features reveals that adopters tend to perceive consumer effectiveness to be higher place more trust in science tend to estimate lower prices for green electricity tariffs are willing to pay significantly more for other eco friendly products and are more likely to have recently changed their electricity contract than non adopters policy recommendations associated with these findings are provided

should we stop meating like this reducing meat consumption through substitution high levels of meat consumption are increasingly being criticised for ethical environmental and social reasons plant based meat substitutes have been identified as healthy sources of protein that in comparison to meat offer a number of social environmental and health benefits and may play a role in reducing meat consumption however there has been a lack of research on the role they can play in the policy agenda and how specific meat substitute attributes can influence consumers to replace partially replace meat in their diets in this paper we examine consumers preferences for attributes of meat and meat substitute products and develop consumer segments based on these preferences the results of a choice experiment with 247 uk consumers using food labels and mince ground meat illustrate that the type of mince fat content country of origin and price are major factors that influence choice carbon footprint method of production and brand play a secondary role in determining consumers choices of meat meat substitutes latent class analysis is used to identify six consumer segments price conscious healthy eaters taste driven green organic and vegetarian consumers which have different socio demographic characteristics and meat consumption patterns future interventions and policies aimed at reducing meat consumption including labelling provision of more information financial incentives educational campaigns and new product development will be more effective if they are holistic and target specific consumer segments instead of focus on the average consumer

green power voluntary purchases price elasticity and policy analysis abstract green power schemes offer electricity from renewable energy sources to customers for a higher price than ordinary electricity this study examines the demand characteristics of green power in australia and policies which could increase its sales a sample of 250 pooled time series and cross sectional observations was used to estimate a statistically significant elasticity of demand for green power with respect to price of 0 96 with a 95 confidence interval of 68 the wide variation in market penetration between jurisdictions and between countries for green power and the low awareness of green power found by surveys indicate that green power sales could be increased by appropriate marketing and government policies the most cost effective means to increase sales was found to be advertising campaigns although only one australian example was found in the state of victoria in 2005 it was also found that full tax deductibility of the green power premium to residential customers exemption from the goods and services tax and a tax rebate for green power are all probably less cost effective for promoting sales than direct government purchase of green power in terms of cost per unit of increased sales
