Granted, but let's say you replace our entire automotive fleet with electric cars. How much capacity would we need for that? You have to have size the electric power grid to satisfy the peak consumption, whenever that occurs. Since 90% of the transportation is done during daylight hours, and the range for electric vehicles is still comparatively low, what pressure do you think we would put on the grid by the reality of having to supply power to cars during the day? Then the whole notion of being able to pull power from cars into the grid during peak demand hours somewhat flies in the face of reality. How is it you're going to pull power from all of these cars when they are most needed? The most opportune time to pull power from them is at night when we don't need it.
