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...
Frictionless future for energy

STEPHENTOWN, N.Y. -- The technology contained in a new, first-of-its-kind 20-megawatt flywheel energy storage facility has the potential to make renewable sources of power such as wind and solar even more viable in the coming decades.
Located on seven acres within a couple of miles of the Massachusetts state line, the 3.5 acre storage facility consumes no fuel and creates no emissions by using flywheels housed in nearly frictionless containers. Using kinetic energy, the flywheels absorb or inject electricity to relieve the grid of excess electricity or to pump up power in the grid during high-usage times.
