ASUS MB27A
At the standardized usage ENERGY STAR assumes, the ASUS MB27A consumes 52 kWh a year — about $9.78 at the U.S. average electricity rate ($0.81 a month). Efficiency-wise it's unremarkable in a good way: within 15% of the median certified computer monitor (rank 931 of 1482). The same unit costs $6.41 a year in North Dakota but $24 in Hawaii — electricity rates, not the appliance, make the difference.
