It makes solving climate change seem deceptively easy. In fact, though wind and solar can generate all a country’s electricity on some days, renewables still account for less than 8% of the world’s total power output." M6 [7 p6 \: f6 C% a. e1 M0 |, r

注意一下高亮的词。作者的逻辑是这样的——; A! k8 d( u9 d, W, y
(可再生能源【风能和太阳能】只能占全球能源产量的8%不到)→发电方面减少碳排放只是减少碳排放这场战斗中的一部分→燃烧天然气取暖和做饭造成的碳排放至少和烧煤发电一样多→但可再生能源用于取暖却几乎没有得到注意9 O( w8 G5 h3 o+ n8 e

以上所说的,归结为一句话:百分之百可再生能源根本不具可行性。
