That's both a function of technological efficiency (direct heating vs heat pump), and the temperature deltas we need to achieve. Using my Southern Ontario reference point, typical cooling needs are only 10-20 degrees C, while typical heating needs would be closer to 20-30 degrees. As use of heat pumps increase, and average temperatures continue to climb, the balance between heating and cooling costs will shift (this is obviously a very regional phenomenon).
