Internal combustion engines are incredibly inefficient, compared even to coal plants.

  They're around 20%. Increasing that to 50-60% (as you need t consider the inefficiencies of batteries, transportation of electricity, not just the efficiency of the motor itself) won't save the planet. It helps, but what we need is fusion or something like that.

    Reducing automotive energy use by a half or two thirds would have an extremely large impact, especially if you consider all of the new autos that will be coming online in India+China. Sure, we still need to switch power generation to cleaner tech as well, but this simplifies the solutions greatly, as power generation will then be concentrated. If we can stop focusing our national attention on trying to secure our oil supplies, we have a better chance at solving the problem as well.
