According to Peter van Doren, a senior fellow at the Cato Institute and editor of Regulation:
Three megawatt hours of electricity would be required for an electric car to travel 12,000 miles a year. But to get the three megawatt hours of electricity to the consumer requires the use of much more generation energy because of losses in transmission and other generator inefficiencies. Thus 11 megawatt hours of generation would be required to get the four megawatt hours to the car. This works out to the equivalent of 38 miles per gallon. This is the same efficiency offered by advanced gasoline, diesel and hybrid engines. And you don’t need to pay $33,000, the suggested manufacturer's retail price of the Leaf, to get them.
The lower marginal costs of electric car operation are offset by the much higher fixed costs of batteries relative to an internal combustion engine of equivalent output.
Yes, the marginal costs of plug-in electric cars are lower than conventional gasoline powered cars: three cents a mile if electricity costs 15 cents per kilowatt hour. Gasoline would have to cost 90 cents per gallon and be used at the rate of 30 miles per gallon to provide equivalent marginal costs. At $3 per gallon and 30 miles per gallon, the marginal costs of conventional cars (10 cents per mile) are more than triple the electric car marginal costs.
But the lower marginal costs of electric car operation are offset by the much higher fixed costs of batteries relative to an internal combustion engine of equivalent output. So for electric cars to be cost competitive, battery costs would have to be much lower (probably about a third of their current costs) or gasoline prices would have to be much higher (above $5 a gallon).
And there would not be carbon-emission advantages from electric cars unless all the new electricity used for cars were renewable. With natural gas-fired generation, the cost of carbon emission reduction from electric cars would be well over $100 per ton, much higher than any carbon tax recommended by economists. Thus, the electric car is not a cost effective answer to all our problems and would not exist without government tax subsidies.

IMO the electric car only serves the Green Agenda. We are living in an Idiocracy.
