Sub-Zero ID-24F

Running around the clock, the Sub-Zero ID-24F uses a certified 377 kWh per year — about $69 at the U.S. average rate, or $5.76 a month, the equivalent of a steady 43-watt draw. Even among certified models it's on the thirsty end: 51% more electricity than the median compact freezer, ranked 123 of 134. The same unit costs $49 a year in Nevada but $199 in Hawaii — electricity rates, not the appliance, make the difference.
