My understanding is that the true impact of a hybrid or electric vehicle is not how the electricity is generated (hydro vs coal vs nuclear etc...) but in how brutal for the environent the mining for the materials to make the batteries is. I recall reading that each volt would have to replace over a hundred already manufactured vehicles before the environmental impact would be less than continuing to drive those older vehicles.
And then you get into what do you do with the batteries when they are done....there are no proper disposal programs for the materials in those next gen batteries.
Electric cars are a feel good placebo to those that don't fully research the realities in my opinion
