　　With 137 gigawatts of installed capacity at the end of 2013, PV has dominated the market —adding more capacity since 2010 than the previous four decades — and will continue to do sothrough 2030, according to the IEA. But once solar reaches from 5 percent to 15 percent ofelectricity generation, the picture changes.

　　根据国际能源署的报告，太阳能光伏在2013年年底的装机容量达到137千兆瓦，在能源市场上占据了主导地位——自2010年至今的新增容量甚至超过了之前40年的新增容量——并会将这种增长势头一直延续到2030年。不过，一旦太阳能光伏占到了各类能源总发电量的5%到15%，局面就会发生变化。

　　At that point, PV begins to lose value in wholesale markets while solar thermal electricity, whichuses the solar to produce steam power, “takes off at this stage thanks to (concentrating solarpower) plants’ built-in thermal storage, which allows for generation of electricity when demandpeaks in late afternoon and in the evening, thus complementing PV generation.”

　　到那时，太阳能光伏发电将会开始在批发市场丧失价值，而利用太阳能产生蒸汽动力的太阳能热能发电技术，则会“在这一阶段开始蓬勃发展，这要归功于(聚光太阳能)电厂内部的蓄热器可在属于用电高峰时段的傍晚和夜间进行热能发电，对太阳能光伏发电形成补充。”

　　Across the globe, China is expected to continue to lead the way on PV, followed by the UnitedStates. Solar thermal, meanwhile, has greatest potential in sunny areas meaning it probablybe a “major opportunity” for Africa, India, the Middle East and the United States.

　　展望全球，预计中国将继续在太阳能光伏领域引领风骚，美国则紧随其后。与此同时，太阳能热能发电则在日照充足的地区拥有无限的潜力，这意味着非洲、印度、中东和美国将迎来“重大发展机遇”。
