LG LT18S1200
Running around the clock, the LG LT18S1200 uses a certified 440 kWh per year — about $83 at the U.S. average rate, or $6.90 a month, the equivalent of a steady 50-watt draw. Even among certified models it's on the thirsty end: 21% more electricity than the median top-freezer refrigerator, ranked 570 of 674. The same unit costs $54 a year in North Dakota but $205 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
