农村居民能源消费涉及能源安全、环境效应、新农村建设等多个方面,从发展趋势来看,在未来相当长的时期内,秸秆、薪柴等传统生物质能仍是我国农村居民的主要生活能源.本文在分析了我国农村居民可再生能源生活消费现状的基础上,测算了1998 -2007年农村居民可再生能源生活消费的碳排放,评估了农村居民可再生能源生活消费的环境效应.得出结论:在我国农村居民能源生活消费的过程中,碳排放的主体是秸秆和薪柴等生物质能的传统利用,其次是商品性能源的使用.在未来的发展过程中,农村居民能源消费必须依靠农村丰富的可再生资源,优化物质循环过程,变生物质能的传统利用为清洁利用,减少温室气体排放,实现改善农村环境,减缓和适应气候变化的总体发展目标.  相似文献

Despite the often mentioned environmental benefits associated with transition from fossil fuels to renewable energy sources, their use for electricity production has non-negligible negative environmental impacts. The most commonly mentioned in surveys concern different types of landscape impacts, impacts on the fauna and flora, and noise. These impacts differ by size and location of plants, and by source of energy, rendering the policy decision complex. In addition, there are other welfare issues to take into consideration, as positive and negative environmental impacts are not evenly distributed among population groups. This paper proposes to compare the welfare impacts of renewable energy sources controlling for the type of renewable as well as the specific environmental impact by source. To this end, two discrete-choice experiments are designed and applied to a national sample of the Portuguese population. In one case, only individual negative impacts of renewables are used, and in another case, the negative impacts interact with a specific source. Results show the robustness of discrete-choice experiments as a method to estimate the welfare change induced by the impacts of renewable energy sources. Overall, respondents are willing to pay to reduce the environmental impacts, thus making compensation for local impacts feasible. Moreover, the estimations reveal that respondents are significantly sensitive to the detrimental environmental effects of specific renewable energy sources, being willing to pay more to use these sources of energy relative to others.  相似文献

A core question in energy economics may be stated as follows: Is the cost–benefit analysis being correctly applied when we encourage investments in renewables, as an alternative to the traditional energy sources? The relationship between energy consumption and economic growth has been extensively treated within economics literature. Yet, literature on the nexus between specific energy sources and GDP is almost inexistent. In this article, we intend to explore the relationship between a certain type of renewable generation technology (solar PV) and GDP. The present and above all the planned energy mix might differ widely from one country to another. Thus, the analysis by source of energy generation becomes a helpful instrument for policy-making. Using a fixed effects panel data methodology and a sample of eighteen EU countries, we find that a 1 % increase in solar PV installed capacity and in electricity production from renewable sources has a positive impact on GDP of 0.0248 and 0.0061 %, respectively. We also conclude that a 1 % growth on greenhouse gas emissions positively affects GDP by 0.3106 %. Further evidence reveals that, in terms of country-specific analysis, Germany, France, Italy and the UK have the most significant estimations for fixed effects. In fact, Germany is a solar PV technology producer, France has a very active nuclear sector, with little pressure for both renewables development and CO2 reductions, Italy had in this period a strong governmental support to this sector, and the UK has a strong connection between the solar PV and the industry sectors.  相似文献

Currently, the progress of science and technology has become a key factor in promoting economic development. And the backwardness of science and technology at the grassroots level has undoubtedly restricted the process of China's construction of socialist new countryside. Taking socio-economy and the development of science and technology in Jiaxing as a breakthrough point, and based on the related data of Jiaxing during 1998-2004, this paper analyzes thoroughly the interactive relationship between socio-economy and the development of science and technology. This paper strives to summarize the development track and model of the grassroots work of science and technology so as to provide local governments with references and grounds for drawing up policies for the local work of science and technology.  相似文献

Due to local scarcity of fossil fuel reserves, deployment of renewable energy has been on the Japanese government energy policy agenda for decades. While a significant amount of government budget was being allocated to renewables Research and Development, in contrast very little attention was paid to public support for renewable energy deployment. Against this background, in 2003, the Japanese government enacted legislation based on the renewable portfolio standard (RPS) scheme, which requires electricity retailers to supply a certain amount of electricity from renewable sources to grid consumers. The RPS legislation had been expected to ensure market efficiency, as well as bringing a steady increase in renewable capacity. Later, in 2009, the feed-in tariff (FIT) scheme was introduced to let electricity utilities purchase electricity generated from renewable energy sources with regulated prices. This paper aims to use the choice of renewable policy as a case-study to understand barriers for policy transfer and innovation, mainly through comparative studies between RPS and FIT in Japan. The result of this study shows that, in Japan, most policy-makers face the ‘lock-in’ of existing technology, which frustrates the deployment of renewable energy. For this reason, there is reluctance to allow experimentation that could promote a shift to other energy sources. In order to achieve the rapid change towards green industry, innovation policy needs to be implemented through effective and efficient methods, such as a carbon tax for fossil fuels; enlargement of renewable energy deployment to sources such as wind, geothermal and solar; and conducting further studies toward public preference and willingness to pay for the new clean energy sources.  相似文献

The 1870–1914 globalization period had profound impacts on the international division of labour, with coal-endowed countries specializing in the production of energy-intensive manufacturing goods and others in the production of agricultural goods. This study analyses the environmental consequences of this specialization, by quantifying the flows of energy and hidden energy embodied in the bilateral trade between the UK, the industrial workshop of the world, and Denmark, a coal-poor country with an agricultural economy. We show that the transformations that occurred in Danish agriculture to meet the growing demand for breakfast foods in the UK required significant quantities of feed and coal. Denmark was a net importer of energy throughout the period and a net importer of hidden energy in 1870. However, by the end of this wave of globalization, Denmark had become a significant net exporter of hidden energy to the UK. This was due both to an increase in its land productivity and to the import of coal, grain and fertilizers from abroad.
