Summit FFBF179SSIM

Running around the clock, the Summit FFBF179SSIM uses a certified 537 kWh per year — about $98 at the U.S. average rate, or $8.21 a month, the equivalent of a steady 61-watt draw. Efficiency-wise it's unremarkable in a good way: within 5% of the median certified bottom-freezer refrigerator (rank 563 of 1478). The same unit costs $70 a year in Nevada but $283 in Hawaii — electricity rates, not the appliance, make the difference.
