> I'm confused, what non-electrical method of generating cabin heat are EVs using, then? Heat pumps are the fancy way to do it that can be installed in both ICEs and EVs. > the heat in the engine block is a byproduct of the combustion required to move the vehicle. That heat isn't "free", but is paid for by the primary purpose of moving the vehicle. Agreed! It's free in the sense that it's already being generated, but it's still waste because it's generated regardless of need as a result of a suboptimal conversion process. We use it as heat because it's unusable for anything else, but it'd be nicer if it wasn't generated in the first place.
