The one point that I think worries me that the author makes is about how much the electric car revolution will really cost in terms of raw materials and lifetime CO2 and environmental issues. Is there anything accurate on the actual pollution cost vs a say a VWs (irony intended) lifetime emissions; it seems incredibly hard to calculate!
