Have you heard the news? We're in a clean energy revolution. And where I live in Berkeley, California, it seems like every day I see a new roof with new solar panels going up, electric car in the driveway. Germany sometimes gets half its power from solar, and India is now committed to building 10 times more solar than we have in California, by the year 2022.

你们看新闻了吗？ 我们正在进行 清洁能源革命。 我住在加利福尼亚州伯克利市， 几乎每天我都会看到新的 太阳能板被装在屋顶上， 电动汽车停在车道上。 德国一半的电力 来自于太阳能， 印度计划在2022年完成 的太阳能板数量， 是加州的十倍。
