LG OLED77B4PU

At the standardized usage ENERGY STAR assumes, the LG OLED77B4PU consumes 263 kWh a year — about $48 at the U.S. average electricity rate ($4.02 a month). It sits near the bottom of the certified table — using 41% more than the median television (rank 137 of 180) — so the state you live in matters more than usual. The same unit costs $34 a year in Nevada but $139 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.
