Indeed, and you did not address two equally important drawbacks of electric cars: A) Electricity is the most highly "refined" energy resource, and it is a law of physics that "it consumes energy to refine energy". So electricity by nature consumes much more energy than gasoline. B) Electric cars weigh 1,000 lbs. more than a gasoline car of similar capacity since batteries are very heavy. How is it good for the environment to haul around all of that extra weight every mile that you drive. Answer: It isn't.
