美国光伏发电现状

Introduction of Photovoltaics in USA

光伏发电在世界目前的电力市场上发展很快,但光伏电池仅占全球电力生产的0．1%左右。在所有可再生能源中,太阳能也只占1%左右。美国的全部光伏发电设施尚不足60MW。2002年秋季,加州参议院通过了1078法案,要求加州的三大电力公司在每年的电力采购中,将可再生能源零售电量每年增加1%,最终到2017年达到20%。目前美国有14个州制定了再生能源投资组合标准(RPS),规定在电力发展中,可再生能源必须占一定的比例。

PV projects are today＇s fastest-growing electrical power generating market segment, but PV cells still account for only around 0.1% of worldwide electricity production. When considered in the context of all renewable generation sources, solar thermal is maybe one percentage point. The entire PV market in the U.S. was less than 60 MW. Caiifornia Senate Bill 1078, passed in the fail of 2002, requires the state＇s three investor-owned utilities to increase their procurement of electricity generated from renewable sources annuaily by 1% of retail sales until the target of 20% is reached by 2017. Fourteen states now in the U.S. have rules, known as renewable portfolio standards （RPSs）, requiring that a certain percentage of the state＇s electricity comes from renewable energy sources.
