If we want to be intellectually honest, heat pumps today can reach 300% to 400% efficiency or even higher, meaning they’re putting out three to four times as much energy in the form of heat as they’re using in electricity. Mining Bitcoin is not a cave enterprise anymore :)

1 electricity w = 3 heat watts with heat pumps if I read correctly.

Heat pumps aren’t effective below -27C or so. Lots of colder places can use miner heat.

For really places it is common to pump heat from the ground instead of air. That way air temperature is not a problem.

Miner waste heat is still a valuable resource but not a primary output.
