AOC 24E3
At the standardized usage ENERGY STAR assumes, the AOC 24E3 consumes 43 kWh a year — about $8.06 at the U.S. average electricity rate ($0.67 a month). Efficiency-wise it's unremarkable in a good way: within 5% of the median certified computer monitor (rank 638 of 1482). The same unit costs $5.29 a year in North Dakota but $20 in Hawaii — electricity rates, not the appliance, make the difference.
