In the short run, the US shale-energy revolution has replaced high-polluting coal with cheaper, cleaner natural gas. This has cut about 300 million tons of US emissions – more than all the world’s solar and wind power combined – and at the same time has profited Americans by saving them $100 billion in energy costs.
对比一下更明智的技术解决方案。从短期看，美国页岩能源革命已经用更便宜清洁的天然气取代了高污染煤炭。此举减少了约3亿吨美国二氧化碳排放——超过全世界所有风能及太阳能减排的总和——同时还为美国人节省了能源开支1000亿美元。
