Electric car benefits? Just Myths

It is time to stop our green worship of the electric car. It costs us a fortune, cuts little CO2 and surprisingly kills almost twice the number of people compared with regular gasoline cars.
Electric cars' global-warming benefits are small. It is advertised as a zero-emissions car, but in reality it only shifts emissions to electricity production, with most coming from fossil fuels. As green venture capitalist Vinod Khosla likes to point out, "Electric cars are coal-powered cars."
The most popular electric car, a Nissan Leaf, over a 90,000-mile lifetime will emit 31 metric tons of CO2, based on emissions from its production, its electricity consumption at average U.S. fuel mix and its ultimate scrapping. A comparable diesel Mercedes CDI A160 over a similar lifetime will emit 3 tons more across its production, diesel consumption and ultimate scrapping.
The results are similar for the top-line Tesla car, emitting about 44 tons, about 5 tons less than a similar Audi A7 Quattro.
Subsidies vs. savings
Yes, in both cases the electric car is better, but only by a tiny bit. Avoiding 3 tons of CO2 would cost less than $27 on Europe's emissions trading market. The annual benefit is about the cost of a cup of coffee. Yet U.S. taxpayers spend up to $7,500 in tax breaks for less than $27 of climate benefits. That's a bad deal.
The other main benefit from electric cars was supposed to be lower air pollution. Yes, it might be powered by coal, but unlike the regular car, coal emissions are far away from the city centers where more people live and where damage from air pollution hits hardest.
However, new research in Proceedings of the National Academy of Sciences found that while gasoline cars pollute closer to home, coal-fired power pollutes a lot more.
