Where this number comes from
Nothing here is estimated from a nameplate wattage; the 278 kWh/yr is ENERGY STAR's own certified figure for this model. The full Dehumidifier category page shows all 546 dehumidifiers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
