True. For residential heating, heat pumps make for a similar ratio as they make 3-5 units of hear for 1 unit of electric energy, depending on conditions.

The challenge in heating is industrial heat, which is much hotter. Can't do that with heat pumps (yet?)

Process heat would be a good use case for SMR nuclear if the economics turn out to be favourable (a big if, admittedly). Also potential for using green hydrogen (though the economics of that are even more iffy).

Even without those, the continued decrease in solar costs means that there's a decent chance that plain old resistive heating will become viable at some point in the 2040s.
