Keystone KSTAD224F
The Keystone KSTAD224F is certified at 278 kWh per year, roughly $52 at the national average — though seasonal use means your real bill lands in a few months, not twelve.

The same unit costs $34 a year in North Dakota but $130 in Hawaii — electricity rates, not the appliance, make the difference.
