Samsung QN98QN90FAF

At the standardized usage ENERGY STAR assumes, the Samsung QN98QN90FAF consumes 357 kWh a year — about $66 at the U.S. average electricity rate ($5.46 a month). Even among certified models it's on the thirsty end: 92% more electricity than the median television, ranked 170 of 180. The same unit costs $47 a year in Nevada but $188 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (180 models), so rankings shift more with each data refresh.
