I don't defend the electric car. In fac, I've always said that electric cars offer absolutely no benefit to the enviroment and have 'cons' like lack of power and autonomy.
And it's not only that cars need an electrcal source (which can come from a coal burning plant) but you have to store all that energy in batteries and when you're doing that you're immediately implying the use of materias such as Nikel, Cadmium, Lithium and Mercury which are among the most dangerous substances in the face of the planet.
However, electricity isn't the only other alternative. There's also hydrogen which burns clean but it still has a long way to go on the development.
Of course the further development of the combustion engines, in particular of the diesel engine, and hybrid technologies help in taking a step forward on enviromental issues.
