MicroFridge 10.0RMF4R

Running around the clock, the MicroFridge 10.0RMF4R uses a certified 263 kWh per year — about $50 at the U.S. average rate, or $4.13 a month, the equivalent of a steady 30-watt draw. That puts it in the most efficient tenth of every certified top-freezer refrigerator — 28% less electricity than the median, ranked 6 of 674. The same unit costs $32 a year in North Dakota but $123 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
