LG OLED77B4PU
At the standardized usage ENERGY STAR assumes, the LG OLED77B4PU consumes 263 kWh a year — about $50 at the U.S. average electricity rate ($4.13 a month). Efficiency-wise it's unremarkable in a good way: within 40% of the median certified television (rank 129 of 172). The same unit costs $32 a year in North Dakota but $123 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (172 models), so rankings shift more with each data refresh.
