LG LW8022IVSM
The LG LW8022IVSM is certified at 387 kWh per year (based on 750 standardized hours), roughly $73 at the national average — though seasonal use means your real bill lands in a few months, not twelve.

The same unit costs $48 a year in North Dakota but $180 in Hawaii — electricity rates, not the appliance, make the difference.
