No one is sure just how many Americans live off the national public-utilities grid - relying on generators or alternate energy sources such as solar, wind and geothermal.
没人知道究竟有多少美国人靠国家公共事业的网络生活—依靠发电机或替代能源，如太阳能、风能和地热能。
Using regulatory mandates has also been a popular way, at the state level, to nudge electricity generators towards getting more of their power from alternative energy sources such as wind and solar.
借助法规要求同样也是通行的做法，在各州，通过诸如风能和太阳能之类的可再生能源，推动发电机来获得更多的能量。
Over time, wind turbines and solar panels may become the dominant generators of power. The nuclear industry is also set for a major expansion.
在不久的将来，风涡轮机、太阳能电池板将成为主要的发电机，核工业也在快速扩张，还在继续运营的碳燃料发电厂将受到严格的碳排放限制。
