清洁能源行动简介

近年来，随着我国石油、天然气和水能开发量的增加，煤炭在能源构成中的比例有所减少，但其主要地位仍未改变，化石燃料的使用与消耗，是构成环境污染的主要来源，目前我国许多城市的空气质量状况较差，严重威胁着城市的发展和人类的健康。据全国３２２个城市空气质量监测统计结果，大气中TSP、SO２和NOx含量超过国家环境空气质量二级标准的城市有２３３个，占统计城市的７２．４％；超过三级标准的１４０个，占统计城市的４３．５％。李岚清副总理批示“从长远来看，石油资源总是越用越少，价格长远攀升的趋势是难以避免的。因此，我们…     

清洁能源和能源的高效清洁利用

前言何谓“清洁能源”?我们认为“清洁能源”应该是指在开采、运输、存储和使用过程中不会或很少向周围环境释放出有害物质的能源。因此,清洁能源是与环境保护关系密切的一种界定能量资源的概念。同时,“清洁”与否也是一种相对的概念。

Grandfathering and coal plant emissions: the cost of cleaning up the Clean Air Act

The Clean Air Act imposes much stricter emission limits on new coal-burning power plants than on older ones — a practice that has no obvious theoretical justification. Elimination of “grandfather rules”, i.e., applying new plant standards to the US electric industry as a whole, would eliminate 40% of nationwide SO₂ emissions and 15% of NO_X emissions, while raising average retail electricity rates by only 4%. Under this scenario, 94% or more of existing coal plants would remain economically competitive with new gas-fired power plants. Policy options for elimination of grandfathering include: an explicit requirement that each existing plant meet new-plant standards; a “cap and trade” system of emission allowances similar to the current SO₂ trading system; and a generation performance standard, an interesting new variant on emissions trading which incorporates a more equitable and flexible allocation of allowances.

Analysis of the Clean Development Mechanism Considering the Environmental Co-benefits of Reducing Air Pollutants in China

An electricity generation planning model of the six major Chinese power grids was developed based on the General Algebraic Modeling System to evaluate and analyze the CDM （clean development mechanism）, including consideration of the environmental co-benefits of reductions in air pollutants （SO~, NO~ and particulate matter） achieved by advanced electricity generation technologies incorporating CCS （carbon capture and storage）. An objective function was developed that included revenue from sales of electric power, total system cost, the cost of CO2 transport and storage, and emissions reduction co-benefits for SOx, NO~, and particulate matter. The objective function was minimized using an optimization model. We also developed a method for evaluating and analyzing the potential for transferring advanced power generation technologies into the Chinese power system through the CDM. We found that： （1） thermal power generation is predominant in the Chinese electricity system and will remain so for a long time; （2） advanced thermal plants are being installed as a result of the CDM, which contribute to decreasing emissions of CO2 and other air pollutants; and （3） CCS projects have significant potential to reduce substantial and sustained CO2 emissions from the Chinese power and industrial sectors.     

Clean Energy Foundation

Established in 1994, the Clean Energy Foundation was set up to help realise and implement projects prepared and developed by an international alternative energy group based at the Hacettepe University Physics Engineering Department, Ankara, Turkey. The New and Clean Energy Group was struggling to advance research and developments at the time so the Turkish Scientific and Technical Research Council (TUBITAK) approached the issue positively and decided that an autonomous organisation was needed to deal with renewable energy application issues in Turkey. As a consequence of this idea the Clean Energy Foundation (CEF) was established as an NGO with 14 individual and 4 organisational members. Professor Demir Inan, President, CEF, Turkey reports on the NGO's activities to date.
