Households in Idaho use 5% more electricity than the national average and pay 25% less than average. Cheap power absorbs most of that: the meter turns faster here, but at 12.35¢ each unit costs less than it does nationally. The climate is fairly balanced — 5,800 heating degree days against 700 cooling ones — so neither season dominates the bill.

What this means for heating
Idaho sees around 150 freezing nights a year. Whether a heat pump beats a furnace here depends on the gap between those two prices above — not on the equipment.
