中国新能源和可再生能源发展状况 总被引:30,自引:5,他引:30
1中国政府重视可再生能源的开发利用中国大规模开发新能源和可再生能源始于20世纪70年代。经过两次世界能源危机的警示,针对我国经济发展出现的能源供应紧张,特别是农村能源短缺(半数农民每年缺柴3~6个月)、热效率低下(只有9%)和大气污染、生态恶化等问题,国务院提出了“因地制宜、多能互补、综合利用、讲求效益”的十六字方针,有力地推动了可再生能源的开发利用工作。1992年联合国环境与发展大会后,中国政府率先制定了《中国21世纪议程》,提出积极开发利用太阳能、风能、生物质能和地热能等可再生能源,保护环境,坚持走可持续发展的道路。1… 相似文献

新能源和可再生能源的分类 总被引:6,自引:0,他引:6
新能源和可再生能源的概念和含义,是1981年联合国在内罗华召开的新能源和可再生能源会议上确定的,它不同于常规化石能源,可以持续发展,几乎是用之不竭,对环境无多大损害,有利于生态良性循环。目前,联合国开发计划署(UNDP)将新能源和可再生能源分为3类:(1)大中型水电;(2)新可再生能源,包括小水电、太阳能、风能、现代生物质能、地热、海洋能;(3)传统生物质能。在我国,新能源和可再生能源是指除常规化石能源和大中型水力发电、核裂变发电之外的生物质能、太阳能、风能、小水电、地热能以及海洋能等。这些能源,资源丰富,可以再生,清洁干净,是… 相似文献

The Inter-Islamic Network on Renewable Energy Sourced was established in 1986 to foster cooperative efforts to promote renewable energy technologies among the member otates of the Organization of the Islamic Conference (OIC). Few OIC countries have the resources to establish and maintain a full programme of training, information, exchange, research and development in renewable energy, but collectively their level of accomplishment can be substanial. 相似文献

This study aims to assess the state of the art of practices and technologies of energy saving and renewable energy sources in hotels. This will contribute to determining the potential of efficient and sustainable energy technologies integration. Hotel managers were interviewed face to face and information sessions were provided. Special energy and environmental awareness campaigns, sectoral tourism programs for climate change mitigation and adaptation, supportive policies and hotel energy investments and renovation programs are some recommendations elicited from the results of this study. 相似文献

For several years recently, the price of oil has fluctuated due to the weak US dollar and financial risks. In particular, the WTI crude oil price reached $147 per barrel in July of 2008, which is the highest price thus far. An awareness of an impending crisis and concern over climate change are driving an increase in R&D for alternative energy sources instead of fossil‐based energy. However, the researches based on traditional method show negative options about the economic value of new and renewable energy. This paper evaluates the value of new and renewable energy through a real option method which considers the uncertainty associated with fossil energy and the uncertainty of the success of R&D. The evaluating model assumes that the fossil energy price follows a geometric mean reverting process and that the probability of success with R&D on renewal forms of energy follows a binomial probability model. The model considers four options: the option to continue R&D, the option to delay R&D, the option to deploy R&D, and the option to abandon R&D. Finally, the value of Korean R&D on renewal forms of energy is analyzed by the model. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

This paper approaches one of the main problems of rural electrification: the choice of the most appropriate technology for each case. The main objective of this project is to apply Geographical Information Systems (GIS) to divide the research zone into areas in that are more appropriate for either conventional or renewable technologies. The approaches for choosing among the different technologies are usually technical and economic; these may be jointly considered by the leveling electric cost (LEC). Determination of the LEC is a complex task that requires knowledge of the capacity factor. This paper shows the conclusions of the technical and economic parameter analysis involved in the determination of the LEC for each technology. This analysis has allowed us to carry out proposals of improvement in the methodology of the GIS of rural electrification. The resulting GIS has been verified in the municipality of Lorca (Murcia, Spain). 相似文献
