不考虑燃烧化石燃料对全球气候的有害影响（1,2），其他能源在未来将变得更加重要，因为按照目前的消费速度(4)，化石燃料可能在22世纪初(3)耗尽。这意味着人类迟早会严重依赖可再生能源。在这里，我们模拟了相对于典型浓度路径2.6情景（RCP2.6；参考文献5）的背景气候，理想的可再生能源大规模应用对全球和区域气候的影响。我们发现，与没有太阳能电池板的气候相比，太阳能电池板单独通过将入射的太阳能转化为电能来诱导区域降温。将这些电能转化为热能，主要是在城市地区，增加了区域和全球的温度，从而补偿了冷却效应。然而，这些过程所涉及的后果是调节全球大气环流，导致区域降水的变化。
Regardless of the harmful effects of burning fossil fuels on global climate(1,2), other energy sources will become more important in the future because fossil fuels could run out by the early twenty-second century(3) given the present rate of consumption(4). This implies that sooner or later humanity will rely heavily on renewable energy sources. Here we model the effects of an idealized large-scale application of renewable energy on global and regional climate relative to a background climate of the representative concentration pathway 2.6 scenario (RCP2.6; ref. 5). We find that solar panels alone induce regional cooling by converting incoming solar energy to electricity in comparison to the climate without solar panels. The conversion of this electricity to heat, primarily in urban areas, increases regional and global temperatures which compensate the cooling effect. However, there are consequences involved with these processes that modulate the global atmospheric circulation, resulting in changes in regional precipitation.
