Smog Casts a Shadow on China's Solar Farms
笼罩太阳能电站上空的雾霾
The wintertime smog in China's northeastern provinces is so severe it blocks more than 20 percent of sunlight from reaching the region's solar panels.
在中国东北部省份的冬季，严重的雾霾可导致其覆盖区域20%的阳光无法到达太阳能板。

China is notorious for its heavy smog. "It's incredibly bad." an atmospheric scientist at Princeton. "The air pollution in eastern China can be so bad you can't clearly see across the street. It can feel like you're walking through a heavy fog that's burning your lungs."
人尽皆知,中国有厚重的雾霾。“那真是太糟糕了。” 在普林斯顿做环境科学研究的专家Denise Mauzerall说。“在中国东部，空气污染糟到你不能看清马路对面。穿行其中，你会感觉好像正在穿过一团能使肺部烧起来的浓雾。”
But smog has other damaging effects too. Mauzerall and her team have found that in winter months the smog in China's northeastern provinces is so severe it blocks more than 20 percent of sunlight from reaching the region's solar panels.
但雾霾还会产生其他破坏性的影响。Mauzerall与她的团队发现，冬季时,在中国东北部省份,严重雾霾的遮挡可导致其覆盖区域20%的阳光无法到达太阳能板。
The findings, based on satellite data and photovoltaic performance models, are in the Proceedings of the National Academy of Sciences. [Xiaoyuan Li et al., Reduction of solar photovoltaic resources dueto air pollution in China]
这项采用了卫星和光伏性能模型数据的研究成果刊登在美国国家科学院的期刊上。
One solution to the problem might be installing even more solar. "There's this virtuous cycle—whereas if you use more solar electricity, you can reduce your use of coal. And that will reduce the air pollution levels, and that will then allow you to generate more solar electricity."
解决这个环境问题的一个方法是安装更多太阳能板。“这是个良性循环——如果太阳能利用得越多，煤的使用就越少。空气污染的等级就会降低，就可以利用太阳能发更多的电。”
China hopes to harvest 10 percent of its electricity from solar by 2030. They'll need 400 gigawatts, or about 10 times what we have installed in the U.S. today. It's an optimistic forecast for solar… and hopefully, for China's air quality, too.
中国政府希望到2030年可以利用太阳能收获全国10%的发电量。他们将需要4千亿瓦特的电量，或建设比美国现在多十倍的太阳能板。这是对太阳能利用的乐观预期……希望对中国空气质量的改善也是如此。
