Summit FFBF179SSIM

Running around the clock, the Summit FFBF179SSIM uses a certified 537 kWh per year — about $101 at the U.S. average rate, or $8.43 a month, the equivalent of a steady 61-watt draw. Efficiency-wise it's unremarkable in a good way: within 4% of the median certified bottom-freezer refrigerator (rank 558 of 1458). The same unit costs $66 a year in North Dakota but $250 in Hawaii — electricity rates, not the appliance, make the difference.
