Samsung RF32CG5900

Running around the clock, the Samsung RF32CG5900 uses a certified 781 kWh per year — about $143 at the U.S. average rate, or $11.94 a month, the equivalent of a steady 89-watt draw. It sits near the bottom of the certified table — using 39% more than the median bottom-freezer refrigerator (rank 1449 of 1478) — so the state you live in matters more than usual. The same unit costs $102 a year in Nevada but $412 in Hawaii — electricity rates, not the appliance, make the difference.
