Samsung RS27T5561
Running around the clock, the Samsung RS27T5561 uses a certified 691 kWh per year — about $127 at the U.S. average rate, or $10.56 a month, the equivalent of a steady 79-watt draw. Efficiency-wise it's unremarkable in a good way: within 8% of the median certified side-by-side refrigerator (rank 86 of 119). The same unit costs $91 a year in Nevada but $364 in Hawaii — electricity rates, not the appliance, make the difference.
