LG LF21C6200

Running around the clock, the LG LF21C6200 uses a certified 574 kWh per year — about $108 at the U.S. average rate, or $9.01 a month, the equivalent of a steady 66-watt draw. Efficiency-wise it's unremarkable in a good way: within 2% of the median certified bottom-freezer refrigerator (rank 788 of 1458). The same unit costs $71 a year in North Dakota but $268 in Hawaii — electricity rates, not the appliance, make the difference.
