DELL U4323QEt
The DELL U4323QEt's certified consumption is 118 kWh per year, which prices out to about $22 at the national average rate — your hours of use scale that directly. It sits near the bottom of the certified table — using 162% more than the median computer monitor (rank 1438 of 1482) — so the state you live in matters more than usual. The same unit costs $15 a year in North Dakota but $55 in Hawaii — electricity rates, not the appliance, make the difference.
