虽然化石燃料——煤炭、石油、天然气——仍占世界能源供应的大约85%，但比以往任何时候都更清楚的是，未来属于可再生能源，如风能和太阳能。

While fossil fuels—coal, oil, gas—still generate roughly 85 percent of the world's energy supply, it's clearer than ever that future belongs to renewable sources such as wind and solar.

再生能源是间歇性的，比如风能、太阳能：没有常刮的风，也不会总是阳光灿烂。

Renewable sources of energy such as wind and solar power are intermittent. The wind doesn't always blow; the sun doesn't always shine.

他说，等得越久——即越晚使用如风能或太阳能之类的可再生资源替代化学燃料，遏制全球变暖的代价就越高。

He said costs of containing global warming, by switching from fossil fuels toward renewable energies such as wind or solar power, would rise the longer the world waited.
