Who's to say that the power I generate during the day isn't being used to charge my car. The grid is also a pretty useful battery. It really doesn't take that long to charge the car after the commute. In winter, chances are that it's from municipal power, summer it's probably from my solar. Either way I'm offsetting my car use with clean, local power.
