Samsung QN65QN90DAF

The Samsung QN65QN90DAF's certified consumption is 266 kWh per year, which prices out to about $49 at the national average rate — your hours of use scale that directly. It sits near the bottom of the certified table — using 43% more than the median television (rank 139 of 180) — so the state you live in matters more than usual. The same unit costs $35 a year in Nevada but $140 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.
