Right - in fact, from my knowledge, heat pumps only see use over direct electrical heating because they are effectively more than 100% efficient. They move more heat energy from outside to inside than they use in the transmission.

The breakdown between gas and electric heating isn’t necessarily a matter of how efficiently the energy is used once it gets to the home, it’s how expensive it is to get it there in the first place. In a lot, if not a majority, of places, it’s much cheaper to get gas piped in than it would be to pay for the same amount of heating via direct electric resistance. Heat pumps change the equation because they can make electric heating in places that don’t get outrageously cold economically competitive with gas.

I will note, while I find my namesake’s story interesting, I do quibble on the benefits of bombardment by multiple-reentry thermonuclear warheads.

Yeah like, I can understand a hesitation around being directly involved in a war effort, but mate once you’ve opened your system up to the military you’re kinda already there.
