Samsung RF32CG5900

Running around the clock, the Samsung RF32CG5900 uses a certified 781 kWh per year — about $147 at the U.S. average rate, or $12.26 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 1430 of 1458) — so the state you live in matters more than usual. The same unit costs $96 a year in North Dakota but $364 in Hawaii — electricity rates, not the appliance, make the difference.
