...which is why I specifically talked about people "whose homes used electrical resistance heating". Many areas do not have gas available by pipe, and having it delivered by truck in liquid form is often expensive. People living in rental units may not be allowed to install a heat pump, and heat pumps have a high up front cost that keeps out many people who aren't blocked by any other restrictions.

Also, even people with other, more efficient, heat sources might have situations where electrical resistance heat makes sense. For example, it may save money at night to turn down a whole house heat pump to a level that would be uncomfortably cold, and use an electrical space heater to just keep your bedroom warmer.
