That was intensely interesting. Unfortunately , I think partly because it is so scary. I apologize because what I am about to say has probably been addressed already, but, hybrid cars, and electric cars still need electricity that is generated by coal and oil. Not to mention (though I am not sure this statistic is entirely accurate) the mass production of the batteries in electric engines would need so much nickel, that the production on average of a single electric car would have a more negative impact on the environment than a standard vehicle. Can anyone confirm this?
