AOC 27E4CV
At the standardized usage ENERGY STAR assumes, the AOC 27E4CV consumes 53 kWh a year — about $9.93 at the U.S. average electricity rate ($0.83 a month). Efficiency-wise it's unremarkable in a good way: within 17% of the median certified computer monitor (rank 940 of 1482). The same unit costs $6.51 a year in North Dakota but $25 in Hawaii — electricity rates, not the appliance, make the difference.
