This paper investigates the willingness to pay of a sample of residents of Bath, England, for a hypothetical program that promotes the production of renewable energy. Using choice experiments, we assess the preferences of respondents for a policy for the promotion of renewable energy that: (i) contributes to the internalization of the external costs caused by fossil fuel technologies; (ii) affects the short-term security of energy supply; (iii) has an impact on the employment in the energy sector; and (iv) leads to an increase in the electricity bill. Responses to the choice questions show that our respondents are in favour of a policy for renewable energy and that they attach a high value to a policy that brings private and public benefits in terms of climate change and energy security benefits. Our results therefore suggest that consumers are willing to pay a higher price for electricity in order to internalize the external costs in terms of energy security, climate change and air pollution caused by the production of electricity.  相似文献

Technology Roadmapping (TRM) is a growing technique widely used for strategy planning and aligning technology with overall business objectives. Technology roadmaps are extensively used in many diverse fields at product, technology, industry, company and national levels. An increasing number of articles published on TRM and technology roadmaps indicate that there is a growing attention for TRM among the researchers from academia, industry and government. In this article, an overview of the application of TRM in renewable energy sector has been provided. After survey of the relevant academic literature and industry roadmaps, we tried to group the roadmaps related to the renewable energy technologies into national, industry/sector and organizational level roadmaps. Research findings indicate that goals and objectives of renewable energy roadmaps are different at these three levels. At national level, roadmaps focus on future energy security, energy dependence, energy policy formulation and environment protection. At industry/sector level, roadmaps are used to identify vision, common needs and evaluate barriers, constraints and risks faced by the industry from technical, political and commercial aspects. Organizational roadmap focuses on evaluation and prioritization of R&D projects to achieve the business goals. Similarly different methods, tools and approaches are used to develop roadmaps at different levels. Various other characteristics of these roadmaps are also discussed and analyzed. Research findings also indicate that greater numbers of roadmaps are developed for those renewable energy technologies undergoing rapid growth. Moreover, most of these roadmaps are developed in the regions where more research, development and deployment activities of renewable energy technologies is taking place.  相似文献

Renewable energy is worldwide seen as a key element necessary to address climate change. However, finding socially acceptable locations for renewable energy facilities and the accompanying infrastructure increasingly often faces fierce opposition. This paper quantifies the landscape externalities of renewable energies employing a choice experiment. In addition, it is investigated how accounting for non-compensatory choice behavior, i.e. attribute cut-offs, affects welfare measures and subsequently policy recommendations. The empirical application is Germany where we conducted a nationwide survey on the development of renewable energies. We first show that cut-off elicitation questions prior to the choice experiment at least partially influence preferences. We further find that most participants state cut-off levels for attributes. Many are, however, at the same time willing to violate the self-imposed thresholds when choosing among the alternatives. To account for this effect, stated cut-offs are incorporated into a mixed logit model following the soft cut-off approach. Model results indicate substantial taste heterogeneity in preferences and in the use of cutoffs. Also, welfare estimates are substantially affected. We conclude that welfare changes from renewable energy development could be strongly underestimated when cut-offs are ignored.  相似文献

This article presents a choice experiment analyzing multifunctional rural development policies targeting conservation and recovery of environmental, social and cultural assets. In choice experiments a base alternative is usually included in order to estimate the welfare change associated to policy proposals. This study is concerned with the much neglected issue of the impact on policy analysis of the definition of a ‘status quo’ alternative either as an objective assessment by experts, or as a self-reported perception by respondents. Convergent validity analysis and prospective policy scenarios show a significant impact of different status quo specifications on individuals' preferences and related welfare measures when complex and unfamiliar biophysical systems are involved in policy analysis and evaluation.  相似文献

In order to reduce future dependence on foreign oil and emissions of CO2, how much would US households be willing to pay annually to support increased energy research and development (R&D) activities designed to replace fossil fuels? Does it matter whether the R&D includes nuclear energy options? We explore these questions using data from a unique set of national telephone and Internet surveys. Using a national advisory referendum format, the contingent valuation method is applied to estimate annual household willingness-to-pay (WTP) for US household support of a national Energy Research and Development Fund (ERDF) for investments in energy sources not reliant on fossil fuels. While accounting for the level of (un)certainty in voting responses, the WTP modeling includes a comparison of both classic maximum likelihood estimation (MLE) and Bayesian analysis. Evidence indicates that MLE and Bayesian analysis achieve similar statistical inference, while the Bayesian analysis provides a narrower confidence interval around estimated WTP.  相似文献

The application of attribute-based choice questions is well established in the marketing literature, but there are unique aspects of the design that warrant investigation to assess their validity for economic welfare estimation. Three design issues are investigated in this paper: (1) the placement of the monetary stimulus (policy cost to respondents) in the sequence of attributes, (2) the number of policy alternatives respondents are asked to consider in choice questions (two versus three), and (3) the inclusion, versus exclusion, of a status-quo alternative in choice questions. The data used to implement these investigations are from a survey designed to estimate the value Maine residents place on a farmland conservation easement program. Tests of convergent validity indicate that the placement of the monetary stimulus, first versus last in the list of attributes, did not affect estimates of preference parameters, significant differences between questions with three versus two alternatives did occur, and the inclusion/exclusion of a status-quo alternative did not affect preference parameters.  相似文献

This paper compares two methods for determining policy priorities for reform of Scottish agricultural support. Multifunctional agriculture attempts to establish a new balance between traditional commodity support and payment for the production of non-market goods and services that are increasingly demanded by the public. Supplying non-market goods presents particular problems for optimal policy design, not least the elicitation of consumer demand for those goods. From public focus groups, a range of attributes was derived as central to the Scottish public’s preferences for future agri-environmental reform. This information was then combined in two separate survey methods using the Analytical Hierarchy Process (AHP) and choice experiments (CE). Both applications suggest that the public has defined preferences and a willingness to pay (using general income taxation) to affect changes beyond the status quo, and that policy payments should be targeted towards both environmental and social benefits. The divergent preference orderings derived from the alternative methods can be considered in the light of previous methodological debates on question framing, bounded rationality and respondent uncertainty. We speculate about the validity of alternative methodologies for informing particular policy questions.  相似文献

The production of energy from renewable sources is much more intensive in minerals than that from fossil resources. The scarcity of certain minerals limits the potential for substituting renewable energy for scarce fossil resources. However, minerals can be recycled, while fossil resources cannot. We develop an intertemporal model to study the dynamics of the optimal energy mix in the presence of mineral intensive renewable energy and fossil energy. We analyze energy production when both mineral and fossil resources are scarce, but minerals are recyclable. We show that the greater the recycling rate of minerals, the more the energy mix should rely on renewable energy, and the sooner should investment in renewable capacity take place. We confirm these results even in the presence of other better known factors that affect the optimal schedule of resource use: expected productivity growth in the renewable sector, imperfect substitution between the two sources of energy, convex extraction costs for mineral resources and pollution from the use of fossil resources.  相似文献

Livestock form key components of the livelihood strategies of many of the world's poorest people. However, despite the potential to alleviate poverty and improve food security through livestock development interventions, the lack of smallholders' participation in the planning and design of breeding programs has often been a major cause of the failure of such programs. Particularly in developing countries where livestock production is still mostly subsistence-oriented and livestock fulfil manifold functions a considerable number of livestock breeding programs have failed. The development of adequate tools to characterise these functions, bearing in mind that these are expressed only rarely in properly functioning markets, is therefore important.This paper seeks to advance the application of such methodologies to the smallholder pig sector in Vietnam. A choice experiment was applied across 140 households involved in pig breeding in order to assess farmers' preferences and the trade-offs for a list of adaptive and productive traits. These included growth, reproduction, disease resistance, feed requirements and appearance.The findings indicate that smallholders highly value both adaptive and performance traits, particularly in resource-driven (i.e. subsistence) production systems. Performance traits were more highly valued in the demand-driven (i.e. market-oriented) systems. These findings have implications for breeding program breed choice and breeding objectives.  相似文献

Science and technology for renewable and sustainable energy are indispensable for our future society and economics. To meet the goal of sustainable energy development, there is a growing body of research efforts world wide. The planner of energy research has to grasp the broader coverage of scientific and technological research, and make decisions on effective investment in promising and emerging technologies especially under circumstances of limited resources. In this paper, we track emerging research domains in energy research by using citation network analysis. Our analysis confirms that the fuel cell and solar cell are rapidly growing domains in energy research. We further investigate the detailed structure of these two domains by clustering publications in these domains. Each citation cluster has characteristic research topics, and there is a variety of growth trends among the clusters. By using citation network analysis, we can track emerging research domains among a pile of publications efficiently and effectively.  相似文献

This paper examines the role of simplified heuristics in the formation of preferences for public goods. Political scientists have suggested that voters use simplified heuristics based on the positions of familiar parties to infer how a proposed policy will affect them and to cast a vote in line with their interests and values. Here, we use a two-stage field-survey experiment to investigate how knowledge of party positions affects policy choices. We followed standard procedures in developing an attribute-based choice experiment on alternative land-use policies in Switzerland. In contrast to the usual formulation, however, the hypothetical costs of the proposed policies were formulated as a percentage change in taxes. The benefit of this formulation relative to the usual absolute money amounts is that the credibility of the (hypothetical) costs for respondents does not depend on respondent income. Furthermore, the formulation allowed us to solicit party positions on the proposed policies. Six out of eight contacted parties provided their positions. We then conducted a split-sample mail survey where we included a table of the party positions with a subsample of the questionnaires. We report six main experimental results. (1) The response rate of the survey was unaffected by the party positions. (2) The proportion of no-choice answers was decreased by forty percent relative to the control. (3) The party information significantly affected the choices directly and in interaction with respondents' general attitudes towards public spending for nature and landscape conservation and thus affected the way how individuals mapped from general attitudes to preferences for specific policies. (4) The information interacted with educational level in only eight out of forty choice sets, suggesting that even the more educated relied on simplified heuristics. (5) Respondents who knew the party positions were more sensitive to the tax attribute. (6) For respondents with medium and higher tax bills, the resulting willingness-to-pay estimates were decreased by a factor of two to ten relative to the control. These findings suggest that the party information helped the respondents to articulate more consistent preferences than in the treatment without the party information.  相似文献

This work presents a novel gray-based cost efficiency (GCE) model that integrates the gray forecasting model into a two-factor cost efficiency curve model for renewable energy (RE) technologies and identifies the optimal forecasting model for power generation cost of RE technologies. The analytical framework of proposed GCE model improves short-term prediction of power generation cost, and can be applied during the early developmental stages for RE technologies. Empirical analysis is based on wind power data for Taiwan. Time lag of knowledge stock was simulated to represent the actual relationship between R&D expenditures and cost reductions in power generation by knowledge stock. Analytical results demonstrate the GCE model is a useful tool to quantify the influences of cost reductions in power generation. The implications of analytical results are that institutional policy instruments play an important role in RE technologies achieving cost reductions and market adoption. The proposed GCE model can be applied to all high-technology cases, and particularly to RE technologies. The study concludes by outlining the limitations of the proposed GCE model and directions for further research.  相似文献

This paper presents an exploratory evaluation of the market case for green energy. These energy sources are widely considered to have less of an ecological impact than conventional energy sources. The case for green energy is viewed from the multiple perspectives TOP (technical, organizational, personal) framework. The green energy technologies will need to meet certain technical, organizational and personal criteria and resolve key issues in order to address the barriers to market adoption. The multiple perspectives approach facilitates the evaluation of green-energy alternatives as potential new products which would enable organizations and individuals to meet both economic and green criteria that impact customer value creation. Given the present trends of increasing energy use and requirements to minimize environmental impact, green energy adoption may become a key element of strategies to ensure long-term economic growth.  相似文献

The major challenge for filling the financing gaps of green energy is lower rate of return of green projects comparing to fossil fuels. Electricity tariffs are often regulated by governments; It has to be kept in low price to serve for every households as a necessary goods. Sources of revenue from green energy comes only from user charges. Hence it is not so much attractive for private investors. The paper is proposing a model for utilization of the tax revenue spillover of green energy supply by returning the portion of it to green energy projects in order to increase their rate of return. In addition, the paper is proposing a social community based funding scheme for smaller scale green projects (e.g. solar and wind). The paper theoretically and empirically shows that utilizing spillover effect in form of tax return for funding green energy projects will increase the rate of return and make them feasible and interesting for the private investors.  相似文献
