I think focusing on the grid (and future of the grid) should be the priority as EV’s powered by coal aren’t really any better. ——————— Often stated, but wrong: (Poland runs mainly on coal) --- End quote --- So are you arguing we should just replace all fuel with coal powered EVs as one study suggests it might be better? I’m no environmental activist be that sounds like a pretty bad idea to me :P --- End quote --- I presume EVs are better, not because they run from coal, but because they are fuel agnostic (i.e. nuclear, solar, wind, hydro, waste veggie oil, timber, hydrogen, natural gas, mice running in wheels, whatever). --- End quote --- EV efficiency reduces component count not to mention regen. No transmission, There's a reason diesel electric locomotives and heavy equipment exist. --- End quote --- Traditional diesel electric locomotives do NOT have batteries to capture regen energy, thus energy efficiency is no different to any other ICE. i.e. braking is converted into heat. |

Well, stone age. Do we realize that most of electricity generated worldwide comes from burning fossil fuels, coal being one of the most popuiar? It's barely less stone age than burning wood. |
