Liebherr C7620

Running around the clock, the Liebherr C7620 uses a certified 305 kWh per year — about $57 at the U.S. average rate, or $4.79 a month, the equivalent of a steady 35-watt draw. Only a handful of certified bottom-freezer refrigerators do better: it ranks 19 of 1458 and undercuts the median by 46%. The same unit costs $38 a year in North Dakota but $142 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
