Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Refrigerator category page shows all 4,704 refrigerators ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
