作为能源相对匮乏的国家,德国将发展可再生能源作为其能源战略的一个重要组成部分。德国政府认为,发展可再生能源对保证能源多样性、减少环境污染以及把握技术革新先机都至关重要。德国2004年8月生效的新《可再生能源法》对2000年出台的类似法律进行了修订和补充,保证20年内为可再生能源电力给予一定的补偿。新法规明确提出,到2020年使可再生能源发电量占总发电量的20%。德国2004年还新出台了市场刺激措施,用优惠贷款及补贴等方式扶持可再生能源进入市场。德国联邦政府曾从长远出发,制定了促进可再生能源开发的《未来投资计划》,迄今已投入… 相似文献

Brownfields that are reused for the generation of renewable energy are called brightfields. This rapidly emerging idea advocates the combination sustainable site reuse and the generation of electricity from renewables. While programmes like the RE-Powering America's Land Initiative herald its benefits, academia knows but little of its barriers and challenges. This study aims to examine the technical/environmental, regulator/financial/institutional, and social barriers to this type of development, along with measures that may address them. The barriers and measures were predominately identified via a qualitative and quantitative survey sent to brightfield developers (experts), along with a review of case studies and the emerging brightfield literature. The study found that environmental/technical barriers only differ from ‘conventional’ renewable energy projects (e.g. on Greenfields) in the event of site contamination. The latter then is what makes brightfields unique and is the source for a myriad of challenges concerning risk and liability, which cause financial problems and investment hesitance. However, evidence conjectures that there is less contextual public opposition to brightfields compared to conventional renewable energy. 相似文献

我国农村可再生能源发展面临生态文明建设、能源安全趋紧、大气污染严重等新的形势变化。作为农业大省,河北省近年来农村可再生能源发展与管理成绩显著,为改善农民生活、保护生态环境、增加能源供应、促进经济社会发展等做出了积极贡献。但新形势下,其农村可再生能源管理也暴露出了思想认识不足、部分法规政策滞后、缺乏宏观科学规划、资金筹措机制单一、后续监督管理不够等问题,需要从加强宣传教育、提高认识水平,完善规章制度、形成法律体系,制定科学规划、明确目标计划,拓宽融资渠道、稳定资金支持、完善服务体系、加强后续管理等方面完善管理与政策,以推进其健康持续发展。 相似文献

This article presents an empirically based model, WiCTS ( Wi thdrawal and C onsumption for T hermoelectric S ystems), to estimate regional water withdrawals and consumption implied by any electricity generation portfolio. WiTCS uses water use rates, developed at the substate level, to predict water use by scaling the rates with predicted energy generation. The capability of WiCTS is demonstrated by assessing the impact of renewable electricity generation scenarios on water use in the United States (U.S.) through 2050. The energy generation scenarios are taken from the Renewable Energy Futures Study performed by the U.S. National Renewable Energy Laboratory of the U.S. Department of Energy. Results indicate reductions in water use are achieved under these renewable energy scenarios. The analysis further explores the impact of two modifications to the modeling framework. The first modification presumes geothermal and concentrated solar power generation technologies employ water‐intensive cooling systems vs. cooling technology that requires no water. The second modification presumes all water‐intensive cooling technologies use closed cycle cooling (as opposed to once‐through cooling) technologies by 2050. Results based on one of the renewable generation scenarios indicate water use increases by over 20% under the first modification, and water consumption increases by approximately 40% while water withdrawals decrease by over 85% under the second modification. 相似文献

Renewable and hybrid energy systems (HESs) are expanding due to environmental concerns of climate change, air pollution, and depleting fossil fuels. Moreover, HESs can be cost effective in comparison with conventional power plants. This article reviews current methods for designing optimal HESs. The survey shows these systems are often developed on a medium scale in remote areas and stand-alone, but there is a global growing interest for larger scale deployments that are grid connected. Examples of HESs are PV–wind–battery and PV–diesel–battery. PV and wind energy sources are the most widely adopted. Diesel and batteries are often used but hydrogen is increasing as a clean energy carrier. The design of an efficient HES is challenging because HES models are nonlinear, non-convex, and composed of mixed-type variables that cannot be solved by traditional optimization methods. Alternatively, two types of approaches are typically used for designing optimal HESs: simulation-based optimization and metaheuristic optimization methods. Simulation-based optimization methods are limited in view of human intervention that makes them tedious, time consuming, and error prone. Metaheuristics are more efficient because they can handle automatically a range of complexities. In particular, multi-objective optimization (MOO) metaheuristics are the most appropriate for optimal HES because HES models involve multiple objectives at the same time such as cost, performance, supply/demand management, grid limitations, and so forth. This article shows that the energy research community has not fully utilized state-of-the-art MOO metaheuristics. More recent MOO metaheuristics could be used such as robust optimization and interactive optimization. 相似文献
