Did you notice I suggested a dependence on solar energy.
On the basis that electric cars be powered by solar do you suggest there is higher environmental damage. Solar to charge the batteries.
Well yes actually. Solar panels are made of Silicon, steel, aluminium and glass. All those materials require high temperature foundries that use vast amounts of power to produce. Ive seen research that shows (depending on the scource of power, mostly coal if from China) that the carbon footprint of manufacturing solar panels can have an enviromental payback time in the order of 15 years, about the same as the usefull lifetime of a solar panel. This is improving all the time with panel efficiency BTW, but as it stands, the enviromental impact of solar panel manufacture/lifetime output use has no enviromental damage advantage over fossil fuel. Are you suprised?.
