My friend Arun Kottoli reviews Electric cars both technically and ecologically. I think it is a brilliant analysis by someone who has been a user of an Electric car for sometime.
I think the ecological issues have to be addressed by reducing consumption and not shifting from one energy source to another. Shifting from petrol or diesel to electricity is just doing that. It may give us a ‘feel good’ factor for sometime, but ultimately we are still consuming non-renewable resources. Only solution is Reduce, Reduce, Reduce.
