Monogram ZIW241NBW

Running around the clock, the Monogram ZIW241NBW uses a certified 118 kWh per year — about $22 at the U.S. average rate, or $1.85 a month, the equivalent of a steady 13-watt draw. That puts it in the most efficient tenth of every certified cooler refrigerator — 33% less electricity than the median, ranked 4 of 48. The same unit costs $15 a year in North Dakota but $55 in Hawaii — electricity rates, not the appliance, make the difference.
