This is true, but it’s shocking how few people have heat pumps, especially in colder climates.
Still, it’s also far less efficient than using a gas furnace (to the point that most people would actually burn more fossil fuels per Joule of heat from a resistive heater than from just burning the gas directly in a furnace).
Of course, if you’re doing something useful with that energy, using the waste heat is an extra benefit. Like using waste heat from a power plant for district heating.
