Samsung QN65S90DAF

The Samsung QN65S90DAF's certified consumption is 251 kWh per year, which prices out to about $46 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 35% of the median certified television (rank 132 of 180). The same unit costs $33 a year in Nevada but $132 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.
