Heating takes considerably more energy than cooling. Especially since most heating is done with natural gas, if homes were heated with a heat pump it would already 2-4x more efficient. Then if you look at the temperature delta between outside and room temp, the cold climates have a much larger difference. Taking 100 degree air down to 75 takes less energy than bring 20 degree air up to 65.
