Cost over its typical lifespan

Shopping for a new one
The Thermador T23IR900SP is already efficient for its category at $53/year. If you're shopping and comparing options, this is roughly what a well-chosen new refrigerator costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have

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.
