ot: Battery technology doesn't come into play as far as energy used. It takes x amount of energy to move the vehicle and it doesn't matter where it comes from (gasoline, hydrogen, battery). As I think about your comment it becomes apparent that battery technology will actually make the grid recharging situation worse. By allowing vehicles to go farther on a charge, people will tend to drive their vehicles farther each day. More average miles per day means more average electricity needed per day, regardless of how often any given user recharges. That's more total energy that has to be taken off the grid and put into the batteries each night. Pure plug ins are not a practical long term solution, even if the batteries can be made to go 1000 miles on a charge. OTOH a plug in with an additional onboard charging system (PEM comes to mind) could be fabulously successful.
