Fisher & Paykel RB36S
Running around the clock, the Fisher & Paykel RB36S uses a certified 150 kWh per year — about $28 at the U.S. average rate, or $2.29 a month, the equivalent of a steady 17-watt draw. That puts it in the most efficient tenth of every certified compact refrigerator — 39% less electricity than the median, ranked 12 of 1645. The same unit costs $20 a year in Nevada but $79 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
