LG 24BR650B

At the standardized usage ENERGY STAR assumes, the LG 24BR650B consumes 46 kWh a year — about $8.40 at the U.S. average electricity rate ($0.70 a month). Efficiency-wise it's unremarkable in a good way: within 2% of the median certified computer monitor (rank 808 of 1530). The same unit costs $6.00 a year in Nevada but $24 in Hawaii — electricity rates, not the appliance, make the difference.
