Leasing car batteries to the power company
Most people, on average, drive their cars only an hour or two a day. The rest of the time, those pricey vehicles sit parked on the street or in some garage. But if those cars had a big bank of batteries – typical of today’s gasoline hybrids or soon-to-hit-the-road plug-in hybrids – they could be earning their owners money while sitting parked. Maybe $5 to $10 a day, just by serving as a back-up energy-storage system for the electric-utility grid.
