Electric cars: Highly charged motoring

The Economist is skeptical about the environmental benefits of electric cars, and in particular their environmental efficiency Highly charged motoring. I of course agree with the notion of a carbon tax, and the gas tax is a weak version of that. The question is then at what rate, which is where the argument should be.

Too bad they don't mention A Better Place, which at least has the potential to solve the charging time issue the article complains about.
