We can meet all of our electricity needs with wind and solar. But what about when the wind isn't blowing and the sun isn't shining? Coal, nuclear and natural gas make up 88% of the U.S. electricity mix. There are several answers to the myth that intermittent energy sources like wind and solar can't replace these dirty energy sources. One of the most exciting is flywheel energy storage, now being pioneered on a commercial scale in New York and soon Pennsylvania. Check it out...
