As they have conveniently "forgotten" the cost of the electricity to charge the car while it's parked, even that figure is wrong. Not only will you save no money on
energy, you will
also lose the upfront money on the cost of the car
and the money to replace the batteries in a few years. Oh, and I wonder how much wear and tear the weight of the batteries will cause on tires and suspension...
Ah, but the important thing is that it makes the greenies feel good, not that it actually saves anything.
