Solar tariffs 太阳能关税 Sunspots 太阳黑子 American tariffs on Chinese solar panels aredangerous and pointless 美国针对中国太阳能电池板的关税是危险且无意义的 SOLAR energy is at a delicate,maybe historic, moment. 太阳能正处于一个微妙的、抑或是意义重大的关头。 The cost of the glassy photovoltaic panels that generate most solar electricityby freeingelectrons from a semi conducting material such as siliconis plummeting. 透亮的光伏电池板花费正大幅下降，它们通过从半导体材料中释放出电子而生产了大多数的太阳能电力。 In the past four years their average cost has fallen by more than 75%. 过去四年当中它们的平均花费跌去了75%以上。 At less than $1 per watt of generating capacity, solar is now the cheapest power source insome sunny places, especially those, like India, that lack fossil-fuelled alternatives. 每发1瓦特电量只需不到1美元，太阳能现在是一些光照充足地区最廉价的能源，尤其是在那些缺少化石燃料替代物的地方，比如印度。 This is starting to look like a revolution. |
