Liebherr ICS5100

Running around the clock, the Liebherr ICS5100 uses a certified 300 kWh per year — about $56 at the U.S. average rate, or $4.71 a month, the equivalent of a steady 34-watt draw. That puts it in the most efficient tenth of every certified bottom-freezer refrigerator — 47% less electricity than the median, ranked 14 of 1458. The same unit costs $37 a year in North Dakota but $140 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
