It's not only about the energy required to run the car (where the owner has influence), but also the kind of energy used to built it. Especially the battery (where the owner or potential buyer has no influence on).

Stoppingdown has a point, and I think this is a valid discussion. The total ecological footprint of current (!) electric cars is something to question. I don't have enough expertise to prove either side right or wrong, but personally I am very sceptic the Tesla way (or generally the electric car way) is the solution of all problems, at least not with the current infrastructure.
