Samsung QN77S95FAF

At the standardized usage ENERGY STAR assumes, the Samsung QN77S95FAF consumes 314 kWh a year — about $59 at the U.S. average electricity rate ($4.93 a month). It sits near the bottom of the certified table — using 67% more than the median television (rank 152 of 172) — so the state you live in matters more than usual.

Note the certified pool here is small (172 models), so rankings shift more with each data refresh.
