How parked cars could power the future

Imagine running a parking meter backwards and actually being paid to park your car. Along those lines, electric vehicles might one day make money for their owners by providing electrical storage for the nation’s power grid.

With this new idea, Vehicle to Grid (V2G), parked electric vehicles would feed electricity back into the grid on an as-needed basis. While this would require a smart grid as well as smart EVs, imagine the results on, say, a 110 degree day in Phoenix when the grid could pull power out of 150,000 parked electric vehicles rather than generating all of it. V2G also decreases the number of backup generators needed by the grid.
