That's a little concerning that its only 65 million. For comparison there are almost 300 million cars in the U.S., so this would be just a 20% adoption rate we are capable of. The reason why I am concerned is not for lack of power, its that I know for a fact the red states in this country will favor making up the slack with fossil fuel based power, because that's significantly faster and cheaper to construct than the best alternative, nuclear power. Even in california nuclear power can hardly catch a break, diablo canyon is limping along, they've already closed san onofre, and I don't think any new power plant is in the pipeline currently.
