modelling seasonality in residential water demand the case of tunisia this article proposes to model seasonal patterns of residential water demand using the techniques of seasonal integration and cointegration the methodology is applied to quarterly aggregate time series data for tunisia 1980 2007 applying the same increasing multi step pricing scheme in the whole country first a seasonal cointegration analysis demonstrates the relevance of a pricing policy that increases the size of the lower consumption block in summer second the nonseasonal cointegration analysis reveals a relatively high price elasticity for the highest consumption block therefore we also propose to increase the tariff progressivity to promote water savings this modified pricing scheme will help to achieve goals of environmental protection and social equity

a comparison of innovation policy in the smart grid industry across the pacific china and the usa abstract utilities are increasing their investment in smart grid technologies because of the rising demand for electricity the aging transmission and distribution infrastructure in developed countries and the need for real time visibility of energy supply and demand to optimize service reliability and cost government policies are contributing to this rising investment in the smart grid in many countries around the globe using rothwell and zegveld s innovation policy framework as a starting point this paper compares innovation policy in smart grids across the pacific specifically china and the usa this research describes the policy tools used by both countries and presents results that indicate national preferences for innovation policy that differ in the ways in which they are linked with the state of the power system china has preferred to use supply side policy which focuses on public enterprise scientific and technical development and legal regulation the usa has preferred to use environmental side policy which focuses on scientific and technical development financial political and public enterprise this paper also describes in detail a number of innovation policies being pursued in the smart grid industry in both china and the usa

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

union experience and worker policy legislative behavior in california 1999 2012 unions influence the u s political process in numerous ways although scholarship has examined labor s effects on political office holding less research is available on the relationship between unions and legislator policy choice in this article i use theories of social identification civic engagement and intergenerational transfer of political values to explore the relationship between various definitions of a legislator s prior union experience and his or her roll call voting once in office i employ multilevel mixed effects regressions to analyze 2 427 federal and statewide worker related votes cast by california s legislators from 1999 to 2012 results indicate that higher probabilities of having worked in a unionized occupation or having a family member who belonged to a union are positively associated with voting for union supported issues the relationship is not cumulative however and is moderated by factors both endogenous and exogenous to the legislator

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

environmental pricing of externalities from different sources of electricity generation in chile abstract the rapid increase in electricity demand in chile means a choice must be made between major investments in renewable or non renewable sources for additional production current projects to develop large dams for hydropower in chilean patagonia impose an environmental price by damaging the natural environment on the other hand the increased use of fossil fuels entails an environmental price in terms of air pollution and greenhouse gas emissions contributing to climate change this paper studies the debate on future electricity supply in chile by investigating the preferences of households for a variety of different sources of electricity generation such as fossil fuels large hydropower in chilean patagonia and other renewable energy sources using double bounded dichotomous choice contingent valuation a novel advanced disclosure method and internal consistency test are used to elicit the willingness to pay for less environmentally damaging sources policy results suggest a strong preference for renewable energy sources with higher environmental prices imposed by consumers on electricity generated from fossil fuels than from large dams in chilean patagonia policy results further suggest the possibility of introducing incentives for renewable energy developments that would be supported by consumers through green tariffs or environmental premiums methodological findings suggest that advanced disclosure learning overcomes the problem of internal inconsistency in sb db estimates

a method to select between periodic cointegration and seasonal cointegration the seasonal and the periodic cointegration models are non nested models that can explain complex patterns in univariate seasonal time series this paper proposes a simple model selection method which is based on an application of the usual test procedures for cointegration to the annual series per season

structure behavior and voter turnout in the united states electoral participation in the united states is examined to provide a clearer account of the effect of the registration requirement on individual voting behavior pooling nes data from 1980 1984 and 1988 i first model with traditional and selection bias techniques the full electorate to distinguish among three groups nonregistrants registered nonvoters and voters analyses limited to recent movers then reported to understand more fully the forces associated with the actual decision calculi of registering and voting the influences of many factors commonly accepted as important determinants of voting are disentangled and their effect at each stage is ascertained factors yielding inconsistent effects in previ research or believed to be unimportant such as race gender attitudes toward the candidates and trust government are shown to deserve closer scrutiny by electoral scholars

the role of public policy in emerging green power markets an analysis of marketer preferences abstract green power marketing has been heralded by some as a means to create a private market for renewable energy that is driven by customer demand for green products this article challenges the premise sometimes proffered in debates over green markets that profitable sizable credible markets for green products will evolve naturally without supportive public policies relying primarily on surveys and interviews of us green power marketers the article examines the role of specific regulatory and legislative policies in enabling the green market and searches for those policies that are believed by marketers to be the most conducive or detrimental to the expansion of the green market we find that marketers 1 believe that profitable green power markets will only develop if a solid foundation of supportive policies exists 2 believe that establishing overall price competition and encouraging customer switching are the top priorities 3 are somewhat leery of government sponsored or mandated public information programs and 4 oppose three specific renewable energy policies that are frequently advocated by renewable energy enthusiasts but that may have negative impacts on the green marketers profitability the stated preferences of green marketers shed light on ways to foster renewables by means of the green market because the interests of marketers do not coincide perfectly with those of society however this study also recognizes other normative perspectives and highlights policy tensions at the heart of current debates related to green markets by examining these conflicts we identify three key policy questions that should direct future research to what extent should price competition and customer switching be encouraged at the expense of cost shifting what requirements should be imposed to ensure credibility in green products and marketing how should the green power market and broader renewable energy policies interact

renewables portfolio standard a means for trade with electricity from renewable energy sources abstract this paper discusses the main support mechanisms for enhancing the deployment of renewable energies re implemented in different industrialised countries the focus is on the electricity sector where deregulation and liberalisation has led to market opening and introduction of competition in the formerly strongly regulated power market under open market conditions price regulation mechanisms in favour of renewable energies which were used by many governments to support renewables tend to be considered as being inappropriate because they lead to distortions in competition and are difficult to abolish once market participants got used to them therefore the idea of creating a demand for re instead of supporting supply is gradually spreading this paper concentrates on the renewables portfolio standard rps which is a considerably new instrument that is aimed on the demand side and has only recently entered discussion it is based on legislatively mandating a percentage share of electricity generated from renewables and proved with certificates before this new means is discussed in more detail a short overview of the existing supply side mechanism is given to point out the different approach in addition examples of some countries already having some experience with the rps are given to show the present status of implementation derived from these theoretical considerations and practical experiences the paper discusses possible impacts on market participants they depend strongly on the outline of the rps and the organisation of the electricity sector adopted as a conclusion the introduction of an rps cannot alone solve the problem of enhancing the use of re however the advantages are a higher degree of competition among generators or developers of re technology more freedom of choice concerning the options for meeting the requirement and perhaps less government expenditures also experiences with national certificate trading within the rps system could ease the way for international or at least european trading systems like the emissions trading as proposed in the kyoto protocol

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

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

power industry restructuring and eco efficiency changes a new slacks based model in malmquist luenberger index measurement measuring variations in efficiency and its extension eco efficiency during a restructuring period in different industries has always been a point of interest for regulators and policy makers this paper assesses the impacts of restructuring of procurement in the iranian power industry on the performance of power plants we introduce a new slacks based model for malmquist luenberger ml index measurement and apply it to the power plants to calculate the efficiency eco efficiency and technological changes over the 8 year period 2003 2010 of restructuring in the power industry the results reveal that although the restructuring had different effects on the individual power plants the overall growth in the eco efficiency of the sector was mainly due to advances in pure technology we also assess the correlation between efficiency and eco efficiency of the power plants which indicates a close relationship between these two steps thus lending support to the incorporation of environmental factors in efficiency analysis

a new unified approach to evaluate economic acceptance towards main green technologies using the meta analysis the aim of this paper is to analyze the main determinants of the economic acceptability of four green technologies gts alternative fuel vehicles energy savings in residential buildings smart meters and renewable electricity using a meta analysis on a sample of 35 selected papers which provided 245 primary data this approach allows detecting relationships across heterogeneous studies avoiding the subjectivity of qualitative surveys we implement a new two step procedure first we compute a measure of the implicit price for a kilogram of co2 avoided pco2 homogenizing the usable information for the gts considered second we conduct a meta regression using the computed pco2 values to estimate the socio economic determinants impact in general our results show a wide degree of acceptability for gts which is stronger among european citizens in particular it emerges that on average the estimated pco2 is positive for the gts considered and additional positive effects exist when respondents are confronted with an explicit reference to quantitative targets in terms of co2 abatement a clear proposal for payment timing and a specific renewable electricity mix these results indicate that information and transparency are crucial to spur gts deployment therefore to support gts market penetration public and private institutional stakeholders have to provide ad hoc information to the end users setting a clear and suitable system of prices to increase the economic value end users place on gts

citizen versus consumer challenges in the uk green power market abstract this paper investigates the potential advantages and disadvantages of green power products as opposed to the traditional fossil fuel levy which was the uk s chosen tax regime as a means of developing renewable energy in the uk willingness to pay for electricity generated from renewables is investigated results indicate that willingness to pay varies with social status and income however results demonstrate that there is a significant minority in full support of some sort of fiscal initiative electricity generated from renewables is a concept supported by the majority however given the stated willingness to pay it is unlikely that any new renewable capacity will result from green tariff schemes in the near term it is concluded that the green citizen must continue to co exist with the green power purchaser if the uk is to make any significant improvement in the contribution of renewable energy to electricity demand the authors would like to acknowledge the support of irene lorenzoni and jane powell of the centre for social and economic research on the global environment university of east anglia leicester energy efficiency advice centre and leicester energy agency

supporting renewable energy on liberalised markets green electricity between additionality and consumer sovereignty abstract the german feed in regulation has been perhaps the most effective promotional policy for green electricity however with the growing momentum of the liberalisation process the current regulation is challenged by structural problems about how to address the demand side price regulation lefts only little room for private green electricity market activities moreover the success of the feed in regulation depends on a strict differentiation of the political segment and the emerging green electricity markets the question therefore is about the role green electricity markets can or should perform in general in order to evaluate green electricity markets the additionality criteria is frequently used implying that markets are only desirable if they lead to additional environmental effects the additionality criteria has two implications first transformed into individual behaviour additionality implies that consumers are assumed to act as pure altruists however there is evidence from empirical studies that green electricity consumers behave more as impure altruists they are not so much interested in the objective environmental impact of their behaviour but more objected to receive a private satisfaction from buying an environmental friendly product whereas theoretical models in the case of pure altruism suggest that private activities crowd out totally when policy becomes active in supporting the public good this crowding out disappears in the case of impure altruism second using end state criteria such as the additionality principle as pre condition and neglecting process criteria such as consumer sovereignty means to prevent establishing competitive market process right at the outset in principle

households willingness to pay for safeguarding security of natural gas supply in electricity generation abstract security of energy supply is a major issue for all eu member states due to europe s increasing dependence on imported fossil fuel sources and the continuous rise in energy demand the latter is of particular importance in electricity sector given the continuously increasing use of gas for electricity generation in order to properly tackle with the problem concerted actions are required by the eu member states in several levels i e legislative political etc nevertheless these actions will come at an additional cost paid by the society either through increased electricity bills or through public financing for energy security investments thus such policies should be justified on the basis of cost benefit analysis towards this direction it may be necessary to take into account non market costs and benefits i e the value that consumers place on interruptions avoided in order to explore households perceptions and willingness to pay for securing gas supply for electricity production an empirical study was conducted by means of the contingent valuation method the results indicate that consumers are willing to pay a premium on their electricity bills in order to internalize the external costs of electricity production in terms of energy security which are caused from imported fuels

willingness to pay lip service applying a neuroscience based method to wtp for green electricity abstract consumers willingness to pay wtp represents a central question for providers of renewable energy most studies on the subject have used contingent valuation and choice experiments however all empirical designs employed to date suffer from serious biases such as strategic behavior we introduce a novel neuroscience based approach to renewable energy related wtp research neuropricing which eliminates some of these biases we tested consumers wtp for two different green electricity products and found wtp for these products to be about 15 above that for a non green electricity tariff our results suggest that neuropricing is indeed able to eliminate strategic behavior moreover this approach allows for wtp studies with much smaller sample sizes than traditional methods require the neuroscience methodology can be used by researchers and marketers alike not only for testing the effects of product attributes on wtp but also for evaluating wtp effects of specific messages in marketing communications thus it may lead to a better understanding of consumer behavior and hence facilitate more successful marketing of renewable energy

financing investments in renewable energy the impacts of policy design abstract the costs of electric power projects utilizing renewable energy technologies rets are highly sensitive to financing terms consequently as the electricity industry is restructured and new renewables policies are created it is important for policymakers to consider the impacts of renewables policy design on ret financing this paper reviews the power plant financing process for renewable energy projects estimates the impact of financing terms on levelized energy costs and provides insights to policymakers on the important nexus between renewables policy design and financing we review five case studies of renewable energy policies and find that one of the key reasons that ret policies are not more effective is that project development and financing processes are frequently ignored or misunderstood when designing and implementing renewable energy policies the case studies specifically show that policies that do not provide long term stability or that have negative secondary impacts on investment decisions will increase financing costs sometimes dramatically reducing the effectiveness of the program within u s electricity restructuring proceedings new renewable energy policies are being created and restructuring itself is changing the way rets are financed as these new policies are created and implemented it is essential that policymakers acknowledge the financing difficulties faced by renewables developers and pay special attention to the impacts of renewables policy design on financing as shown in this paper a renewables policy that is carefully designed can reduce renewable energy costs dramatically by providing revenue certainty that will in turn reduce financing risk premiums

the renewable portfolio standard design considerations and an implementation survey renewables have social and environmental bene ts compared to conventional electricity sources but are rarely competitive on a strict nancial cost basis this is because conventional sources are sometimes subsidized their full pollution costs are ignored and renewables involve newer higher cost technologies whose relative costs will fall with commercialization governments use several mechanisms to support renewables including direct nancial support grants loans indirect support r d demonstrations reform of nancial costs of conventional sources subsidy removal pollution taxes and the renewable portfolio standard rps the rps requires a minimum share of electricity from renewable energy sources its use is spreading because it maintains an incentive for renewable producers to reduce costs links the regulated market outcome to an environmental target and reduces government involvement although it is too early to evaluate fully its e ectiveness the survey for this study explored implementation issues in three european countries nine us states and australia and found the following the rps target is usually set to have environmental bene ts without causing signi cant price increases cost caps are sometimes used most jurisdictions limit eligibility to gridconnected domestic renewables the rps is usually applied to producers rather than consumers and to energy output not capacity flexibility mechanisms are desired but a challenge to implement administration in the us and australia is by government with delegation to independent utility regulators while in europe it is more the responsibility of government everywhere the rps is applied alongside other mechanisms of renewables support 2001 elsevier science ltd all rights reserved

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

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

renewable energy policy and electricity restructuring a california case study abstract many countries are in the process of deregulating and restructuring their electric power industries although the introduction of retail competition may have negative impacts on the development of renewable energy a number of countries are establishing new programs to support these clean energy technologies in the united states debate has centered on three primary renewables support mechanisms 1 the renewables portfolio standard 2 programs funded by an electricity distribution surcharge and 3 voluntary renewable energy purchases by electricity customers via green power marketing california provides a good case study of the design of renewables support programs within industry restructuring because policymakers considered all three of these options during the state s restructuring proceedings moreover many of the same policy options design issues and political conflicts that have arisen in california are likely to recur in other states and countries some of the most important lessons from the california experience include 1 renewable energy and environmental advocates must clearly articulate the need and rationale for continued support of renewables 2 cost containment and competitive neutrality concerns must be addressed head on 3 combinations of policies are likely to be far more effective than any single renewables policy and 4 the effectiveness of renewable energy policies developed during the restructuring process will be strongly linked to their duration and stability

valuing a wind farm construction a contingent valuation study in greece abstract our analysis is based on data from a double bounded dichotomous choice contingent valuation study implemented to elicit public attitudes towards renewable energy generation and their willingness to pay for the construction of a wind farm in the area of messanagros in the island of rhodes greece results indicate that there are significant positive values deriving from the proposed project respondents report a mean willingness to pay a premium in their bi monthly electric bills of 8 86 for the sole purpose of the construction of the wind farm the estimated economic benefits to the local population are weighed against the investment cost in a cost benefit analysis to inform policy making and implications for eu energy policy are provided

impacts of a common green certificate market on electricity and co2 emission markets in the nordic countries abstract the purpose of this study is to analyze the effects of introducing a common nordic system for tradable green certificates tgcs on the electricity market and a future market for tradable co 2 emission permits teps in the analysis the energy system model generator markal was used to model the electricity and district heating supply systems in the four nordic countries sweden norway finland and denmark it is shown that the introduction of tgc quotas reduces wholesale electricity and tep prices the impact on the latter is very pronounced retail electricity prices may become lower or higher depending on the tgc quota than if obligations to fulfill tgc quotas were absent the tgc scheme s efficiency in reducing a specific amount of co 2 emissions is also compared to the corresponding efficiency of a tep scheme involving a broader range of technologies furthermore obligations to fulfill tgc quotas affect investment incentives for new non renewable electricity supply this seems especially true for gas fired power plants finally it is indicated that electricity supply based on biomass combustion dominates the tgc scheme at least in the short run

seniority political experience and support for government spending in the us house a culture of spending payne 1991a postulates that there is a culture of spending in the us congress whereby members of congress are socialized to increase their roll call support for more spending as a function of length of service and exposure to the washington culture in this article we develop and test an expanded model of roll call voting on spending matters focusing on two potential sources of socialization effects 1 exposure to the washington culture of spending primarily through seniority and proximity to washington dc and 2 previous political experiences developed before members are elected to congress using data for us house members from the 93rd through the 107th congresses we estimate a series of models in which we explain national taxpayer union scores as a function of seniority previous political experience personal attributes and a range of constituency variables we find strong and consistent seniority and political experience effects with senior members and those with extensive political experience more likely to support greater spending than other members these findings withstand a range of robustness tests

public attitudes toward government spending this study examines the nature sources and consequences of citizens attitudes toward government spending data from the 1984 cps national election study are used to perform a scaling analysis of mass spending preferences across a set of 10 public policies the empirical results indicate that there is a coherent structure underlying citizens attitudes toward social welfare spending in contrast spending preferences for nonwelfare programs are separate and largely unrelated concerns i argue that this distinction is essential for understanding public opinion on government spending and further analyses incorporating the difference between welfare and nonwelfare spending preferences provide important theoretically relevant insights about the relationship between citizens in the mass public and stimuli in the political world

communications on energy household energy conservation abstract this study assesses the influence of attitudinal and socio economic factors on household energy conservation actions a household interview survey in regina saskatchewan found that respondents perceive an energy problem although no association with energy conservation actions was determined two attitudinal and five socio economic variables influence household energy conservation energy and monetary savings are available to households through energy conservation public awareness of household energy conservation through the media can reinforce existing energy conservation actions and encourage new actions

the public private sector cleavage in north america the political behavior and attitudes of public sector employees this article explores the private public sector cleavage in voting and political attitudes in canada and the united states the authors use public choice theory to hypothesize that the interest of

residential mobility and voter turnout we examine the characteristics of a largely ignored low turnout group people who have recently moved we find that neither demographic nor attitudinal attributes explain their lower turnout instead the requirement that citizens must register anew after each change in residence constitutes the key stumbling block in the trip to the polls since nearly one third of the nation moves every two years moving has a large impact on national turnout rates we offer a proposal to reduce the effect of residential mobility on turnout and estimate that turnout would increase by nine percentage points if the impact of moving could be removed the partisan consequences of such a change would be marginal

market failure and energy policy a rationale for selective conservation abstract appropriate activities for the government in the energy sector of the us economy are suggested on the basis of market failures in this sector alleged market failures are explored and specifically targeted remedies proposed where indicated the resulting government policies can be characterized as selectively conservationist designed to induce lower levels of use of particular fuels sometimes in particular industries

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

the performance of periodic autoregressive models in forecasting seasonal u k consumption the parameters of a periodic model are allowed to vary according to the time at which observations are made periodic autoregressive models are fitted to the quarterly values of seasonally unadjusted real nondurable consumers expenditure for the united kingdom and its components the periodic model offers no improvement over conventional specifications if the aggregate is modeled directly on the other hand periodic models generally perform well for the components which contain additional seasonal information the choice between a periodic or nonperiodic specification is also shown to have an important influence on the resulting dynamic properties

the voting behavior of bureaucrats some empirical evidence this paper has examined the voting behavior of bureaucrats and the consequences for elections the economic theory of the rational voter predicts that bureaucrats would have more to gain by voting than the general public the cost of voting is lower for public employees than for those who work in the private sector as a consequence theory predicts that bureaucrats would participate in elections at a greater rate than other individuals as a test of the validity of the economic theory of voting an empirical analysis of national elections from 1964 to 1978 was presented the evidence is drawn from household survey data published by the u s bureau of the census the data permit a direct observation of voting participation rates of public and private employees the empirical results indicate that bureaucrats consistently participate in elections at significantly greater rates than non bureaucrats as the public sector expands and voter participation rates remain low bureaucrats will exert disproportionate influence on election outcomes

how powerful are public bureaucrats as voters empirical evidence is collected and discussed regarding the influence of public bureaucrats on government sector outcome in their capacity as consumer voters it is necessary to isolate the specific effect of working in the public sector compared to other occupations on voting participation and on the probability to support an increase in the public budget for a balanced evaluation of public bureaucrats power other forms of their influencing the government sector outcome need to be taken into account

measuring the efficiency of grid companies in china a bootstrapping non parametric meta frontier approach abstract the unbundling policy reform of power industry has become a worldwide trend since 1980s there are quite many studies focusing on the efficiency changes of transmission and distribution sectors in european and latin american countries while few reports on china s issues have been found this paper employs a nonparametric frontier estimation combined with meta frontier and bootstrapping method to measure the productive efficiency and changes in the decomposition index for china s 31 grid companies from 2004 to 2013 in addition it further employs tobit regression model to analyze the influences of relevant policies and heterogeneity factors such as natural conditions and economic development the results indicate that the grouping approach extends the application of non parametric data envelopment analysis which may decrease the assumption of homogeneity for the decision making units and provide better efficiency estimates by increasing the credibility of the evaluation results overall productive efficiency increased during the whole study period with technology progress the main contributor to this improvement efficiency trends fluctuated with changes in economic development and power supply situation and the economics and customer density had positive effects on productive efficiency while the influence of clean power proportion is negative

renewable electricity as a differentiated good the case of the republic of korea this paper examines the willingness for korean consumers to pay a premium for renewable electricity under a differentiated good framework by applying the contingent valuation method korean consumers have been required to pay for their use of renewable electricity as of 2012 first we find that korean consumers recognise renewable electricity as a differentiated good from traditional electricity generated from fossil fuels or nuclear energy the mean willingness to pay to use renewable electricity is usd 1 26 per month second we confirm the existence of perfect substitution relationships among variant renewable technologies which suggests that korean consumers do not perceive them as differentiated goods one reason for this perception is that korean consumers are more inclined to favour economic feasibility over sustainability or the availability of the resource stock when choosing between renewable technology types in sum we can say that korean consumers recognise renewable electricity as a differentiated good but that they do not differentiate between variant renewable technologies thus the imposition of the cost of renewable electricity on consumers in the form of increased electricity charges would be acceptable to consumers as long as any price rise properly reflects their preferences

imports as a major complication liberalisation of the green electricity market in the netherlands abstract liberalisation of the green electricity market in the netherlands has proceeded in a context of relatively generous fiscal incentives and in line with the position that demand is the limiting factor to dutch green electricity production the main result was a massive rise of imports partly covered by renewable energy credits and partly virtual in nature whereas the domestic expansion of green electricity production remained limited this shows the importance of a supply side focus in designing policies aimed at the expansion of domestic green electricity production in the context of a common market with different incentives in place

assessment of korean customers willingness to pay with rps abstract to increase the use of renewable energy the korean government will introduce the renewable portfolio standard rps in 2012 the rps places responsibility for extra renewable energy costs on the consumers and allows price competition among different renewable sources accordingly this study analyzes through the contingent valuation cv the willingness of korean households to pay more for electricity generated by wind photovoltaic pv and hydropower our empirical results show that although the willingness to pay or wtp was highest for wind power and lowest for hydropower the differences in wtp among the renewable sources were statistically insignificant this suggests that korean consumers prefer a renewable portfolio that minimizes power supply costs the average wtp for all three energy types was krw 1562 7 usd 1 350 per month per household which was approximately 3 7 of the average monthly electricity bill in 2010 this amount represents only 58 2 of what the korean government allocated in its budget to the new and renewable energy dissemination program in 2010 thus our results imply that the promotion of the new and renewable energy dissemination program may be difficult only with the wtp for electricity generated from renewable sources specifically the mean wtp will not support the set aside dissemination capacity for pv after 2014

supplier choice and wtp for electricity attributes in an emerging market the role of perceived past experience environmental concern and energy saving behavior abstract this study analyzes customers preferences and their willingness to pay wtp for certain service attributes in an electricity supplier choice context specifically a stated preference choice experiment is conducted in the canary islands residential market where limited competition exists preferences for different electricity suppliers and three level of service attributes are investigated namely supply reliability share of renewable energies and availability of a complementary energy audit service the results might be interpreted as an indication of different aspects new firms need to consider if they plan to enter in the market there is an opportunity for new companies to establish in the market though evidence of brand loyalty to the current company and or significant switching costs are also found especially in the case of older people regarding the estimated wtp several results should be highlighted first customers who have experienced more serious outages in the past tend to show a higher wtp to reduce the outage frequency second highly educated respondents those who state a great concern for the greenhouse gases ghg emissions and those who carry out energy saving actions in their homes exhibit a larger wtp for renewable energies this empirical evidence provides useful information for authorities responsible for energy policy design

seasonal cointegration in macroeconomic systems case studies for small and large european countries abstract six variable vector autoregressive systems consisting of macroeconomic series are investigated parallel data series for four european countries are used austria germany federal republic finland and the united kingdom all data series are not seasonally adjusted the aim of the paper is to show that most of the series are better modeled using stochastic seasonality and seasonal unit roots models than simple deterministic models of seasonal structures as a second step seasonal cointegration in the systems is studied it is shown that all four economies display seasonal cointegration as well as usual cointegration

beyond technology push and demand pull lessons from california s solar policy abstract the scale of the technological transformation required to reduce greenhouse gas emissions to safe levels while minimizing economic impacts necessitates an emphasis on designing climate policy to foster or at least not impede environmental innovation there is only a weak empirical base for policy makers to stand on regarding the comparative innovation effects of various climate policy options however empirical scholarship in environmental innovation is hindered by the complexity of both the innovation process and the interactions between the dual market failures of pollution and innovation that are in play and it appears that the field would benefit from the structure provided by a common lexicon this paper focuses on the issues related to policy categorization in this field these issues have received little attention in the literature despite their importance to making insights gained from empirical studies generalizable the paper reviews the origins strengths and weaknesses of the dominant policy typology of technology push versus demand pull instruments its primary contribution however is to assemble a comprehensive chronology of solar policy in california and its impacts on innovation where known and then use this as a basis for building a new policy categorization that takes advantage of the intuitive resonance of the dominant typology while encompassing the broader range of policy instruments that are employed in practice in order to stimulate environmental innovation the most noteworthy aspect of the new categorization is that it introduces a third category of environmental innovation policy instrument that focuses on improving the interface between technology suppliers and users this reflects developments in the economics of innovation literature as well as considerable evidence in the domain of distributed solar energy technologies that opportunism by some of the actors that work at this interface can be a barrier to innovation

california shows the future of electricity production in the single market in california pressure from industrial and commercial ratepayers has initiated liberalization in electricity production this us experience is important because the plausibility arguments against liberalization may reappear in the european debate on the single market

impact of cheaper oil on economic system and climate change a swot analysis abstract the drop in crude oil price by nearly half since june 2014 has created new opportunities as well as challenges this study employs the swot method to analyze the impact of cheaper oil on the global economic system and carbon emissions exploring the climatic opportunities and identifying the challenges of lower oil prices in addition it contends that falling oil prices boost economic growth but produce more carbon pollutants thereby accelerating global warming however cheaper oil has provided a window of opportunity to remove fossil fuel subsidies a major development that years of climate shaming has failed to achieve furthermore we argue that social factors are a critical often overlooked threat for the removal of fossil fuel subsidies with declining oil prices exerting downward pressure on gas and coal the removal of subsidies and carbon tax can be introduced without raising the energy prices four policy recommendations are proposed for the removal of fossil fuel subsidies to limit global warming as well as to meet the challenge and opportunity of cheaper oil removal of fossil fuel subsidies should be quickly implemented because this window of opportunity of cheaper oil will not last forever

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

a seasonal model of consumption in this paper the authors present strong empirical evidence that the long run income elasticity of u k nondurable consumers expenditure and its short run rate of adjustment both vary across seasons such variability in the behavior of consumers is consistent with the hypotheses that consumers have seasonal preferences and that they exhibit seasonally varying degrees of habit persistence the tests are based on a modified form of the error correction methodology that allows for seasonally varying slope coefficients simulations for the dynamic responses of the authors model illustrate the important policy implications of these results coauthors are r c bladen hovell a p l chui denise r osborn and j p smith copyright 1989 by royal economic society

willingness to pay for green electricity in korea a contingent valuation study abstract green electricity is energy that is generated from renewable energy sources such as solar power wind power small scale hydroelectric power tidal power and biomass power these sources mostly do not produce pollutants and are considered environmentally friendly however considering the current state of technology they are more costly government should take visible actions to compensate for the increased production costs this paper attempts to apply a contingent valuation cv method to obtain at least a preliminary evaluation of the benefits that ensue from the introduction of the policy that raises the percentage of green electricity consumption from 0 2 of the total electricity supply to 7 by 2011 overall the cv survey was successful in eliciting the willingness to pay wtp for green electricity considering that the cv method operated within respondents abilities to answer and the wtp estimates were statistically significant the monthly mean wtp estimates from parametric and non parametric methods were krw 1681 usd 1 8 and krw 2072 usd 2 2 respectively the estimates of the annual benefits to relevant residents amounted to krw 150 5 billion usd 157 5 million and krw 185 6 billion usd 194 2 million respectively

are government employees more likely to vote an analysis of turnout in the 1996 u s national election in this paper we develop and test a model of voter turnoutthat permits us to differentiate turnout rates for governmentemployees and other citizens controlling for the effects of awide range of other variables relating to turnout using 1996anes data we find that there is a significant difference inturnout rates for bureaucrats and nonbureaucrats both insimple bivariate analyses and in a full multivariate model the magnitude and significance of the coefficient forgovernment employment even in the face of controls suggeststhere is something about government employment per sethat has an effect on turnout

cost effects of international trade in meeting eu renewable electricity targets abstract the european market for renewable electricity received a major stimulus from the adoption of the directive on the promotion of renewable electricity the directive specifies the indicative targets for electricity supply from renewable energy sources res e to be reached in european union eu member states in the year 2010 it also requires member states to certify the origin of their renewable electricity production this article presents a first eu wide quantitative evaluation of the effects of meeting the targets using an eu wide system for tradable green certificates tgc we calculate the equilibrium price of green certificates and identify which countries are likely to export or import certificates cost advantages of participating in such an eu wide trading scheme are determined for each of the member states moreover we identify which choice of technologies results in meeting targets at least costs results are obtained from a model that quantifies the effects of achieving the res e targets in the eu with and without trade the article provides a brief insight in this model as well as the methodology that was used to specify cost potential curves for renewable electricity in each of the 15 eu member states model calculations show that within the eu wide tgc system the total production costs of the last option needed to satisfy the overall eu res e target equals 9 2 eurocent kwh assuming that the production price of electricity on the european power market would equal 3 eurocent kwh in the year 2010 the indicative green certificate price equals 6 2 eurocent kwh we conclude that implementation of an eu wide tgc system is a cost efficient way of stimulating renewable electricity supply

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

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
