豆腐卤水有望降低太阳能成本

    “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•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。”

    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。（财富中文网）

    “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.”

    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.
