“By contrast,” van der Hoeven said, “where there is a record of policy incoherence, confusing signals or stop-and-go policy cycles, investors end up paying more for their investment, consumers pays more for their energy, and some projects that are needed simply will not go ahead.”
“与之相反,”范德胡芬继续介绍,“有些地方的政策不连贯、不明朗或者时断时续,导致投资者需要为投资付出更高的成本,消费者需要为购买能源付出更高的费用,甚至有一些存在需求的项目最后却难以为继。”
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 so through 2030, according to the IEA. But once solar reaches from 5 percent to 15 percent of electricity 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, which uses the solar to produce steam power, “takes off at this stage thanks to (concentrating solar power) plants’ built-in thermal storage, which allows for generation of electricity when demand peaks in late afternoon and in the evening, thus complementing PV generation.”
