It is not so bad once a) the transformation to solar and other renewable energy has been achieved (not so soon i guess
)
or b) energy sector is switched to nuclear energy (probably not done due to the greens, at least until they begin to hunger or freeze).
As soon as energy for industry and private households is being produced by nuclear power even the electric heating of houses would be possible and not too expensive. Like they do it in France.
And do not say electrical heating is not ecological feasible, after all all the greens want to switch all to electric cars. I guess the energy for all that just comes out of the wall plugs, nothing to worry about.
But then there is new tech like fusion, geothermal energy and so on..
for privates ..
