**Duh. No one ever claimed that an electric car was completely benign. 
It is, however, significantly cleaner than an equivalent petrol or 
Diesel car, even when powered by coal-fired power. That said, Tesla have 
promised to obtain all their electricity from renewable sources for 
their free charging stations. And, as I stated, for many city dwellers, 
any electric vehicle will emit significantly less CO2 (via a coal-fired 
power station) under day to day use. For long distance driving, the 
benefits will be less obvious.

**Cites please.
