One K, ten K, two hundred K years, pretty soon we'll be talking about real geological time.
In terms of me and my foreseeable progeny’s lifetimes we might as well be talking mega-years!
Nuclear power is
BAD!
Greenhouse gasses and other chemical pollutions are necessarily self limiting because if they get bad enough to effect civilization, then the polluting civilization will necessarily cut back on production. Our current "green obsession" is a case in point. Air pollution in the US is significantly better than it was thirty years ago. Not good enough yet, but better.
With nuclear power, if it gets bad enough to effect civilization, it’s too late!
But to remain on topic, in order to determine if electric vehicles are good for the environment it is necessary to know the average efficiencies of all of the power generating, power distribution and power consuming processes involved. All that information is available but frankly I am not interested enough to dig it up.
I suspect, however, that in the final analysis electric cars are good for the environment, but not as good as the tree huggers would have us believe.
