　　In the other solar study, researchers writing in Nature Climate Change this week said concentrating solar power or CSP could supply a large fraction of the power supply in much of the world. The researchers from the Austria-based International Institute for Applied Systems Analysis simulated the construction and operation of CSP systems in four regions around the world taking into account weather, electricity demand and costs. They found that CSP in the Mediterranean region, for example, could provide 70-80% of current electricity demand, at no extra cost compared to gas-fired power plants.

　　《自然气候变化》(Nature Climate Change)杂志本周发表的另一份太阳能研究报告显示，CSP系统可以解决世界大部分地区很大一部分电力供应。来自奥地利国际应用系统分析研究所(International Institute for Applied Systems Analysis)的研究人员模拟了CSP系统在全球四个地区的建设和运营情况，并充分考虑了天气、电力需求和成本等因素。他们发现，CSP系统可以满足地中海地区当前70-80%的电力需求，而且跟燃气电厂相比，它无需支付额外费用。

　　“In order to address climate change we need to greatly expand our use of renewable energy systems,” said IIASA researcher Fabian Wagner, who also worked on the study. “The key question, though, is how much energy renewable systems can actually deliver.”

　　“为了应对气候变化，我们需要加大对可再生能源系统的利用，”这项研究的参与者之一、国际应用系统分析研究所研究员费边o瓦格纳说。“但关键问题是，可再生系统真正能够生产多少能源。”

　　A huge challenge with deploying solar energy on a large scale is that the sun doesn’t shine all the time. That means that energy must be stored in some way. For photovoltaic (PV) cells, which convert sunlight directly to electricity, this is especially difficult to overcome, because electricity is difficult to store.

　　大规模部署太阳能的一个重大挑战是，太阳并不是在所有时间都当空高照。这就意味着，能量必须要通过某种方式存储下来。对于直接将太阳光转换为电能的光伏电池来说，这是特别难以克服的困难，因为电力很难储存。
