Samsung QN85QN90FAF

At the standardized usage ENERGY STAR assumes, the Samsung QN85QN90FAF consumes 345 kWh a year — about $63 at the U.S. average electricity rate ($5.27 a month). It sits near the bottom of the certified table — using 85% more than the median television (rank 167 of 180) — so the state you live in matters more than usual. The same unit costs $45 a year in Nevada but $182 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.
