• It’s the capability for green energy use, in a very energy-intense application. That possibility is not there with combustion engines.

      We cannot have a green energy economy unless all the usage endpoints consume clean energy rather than hydrocarbons.

        • Anything that already runs on electricity isn’t really part of the discussion then, because there’s no need to change anything at the point of use.

          A better analogy to the car thing might be investing in (or subsidizing) heat pump production over natural gas furnaces.
