Despite years of successful experience, dozens of studies, and increasing utility support for clean energy, urban myth holds that electricity from renewable energy is unreliable. Yet over 75,000 megawatts (MW) of wind and solar power have been integrated, reliably, into the nation’s electric grid to date. That’s enough electricity to supply 17.9 million homes. And, as a new NRDC fact sheet published today illustrates, the electric grid can handle much higher levels of zero-carbon wind and solar power, far more than what’s necessary to achieve the relatively modest carbon emission reductions in the U.S. Environmental Protection Agency’s plan to limit pollution from existing power plants. But first, a little background on how our nation’s electric system works. Grid basics The nation’s high-power transmission system is made up of three largely separate grids: one on either side of the Continental Divide (roughly) and the third in Texas. The two largest […]
