Yearly cost by era
- Pre-1993: ~1,500 kWh/yr → $255/yr at $0.17/kWh.
- 1993-2000: ~1,000 kWh/yr → $170/yr.
- 2001-2014: ~600 kWh/yr → $102/yr.
- Modern ENERGY STAR: 350-450 kWh/yr → $60-$77/yr.
The garage-fridge trap
That second fridge in the garage holding two 12-packs and old condiments often costs $150-$300/yr. Unplug it or get rid of it — the savings buy a real beverage cooler in months.
When does replacement pay?
If your old fridge uses 800+ kWh/yr and a replacement costs $900, savings of ~$100/yr give a 9-year simple payback — within typical fridge lifespan. Add a $50-$200 utility rebate and payback drops to 6-7 years.
Tune what you keep
- Fridge at 37-40°F, freezer at 0°F. Colder costs more without preserving food longer.
- Vacuum the condenser coils annually — dirty coils raise consumption 5-15%.
- Replace torn door gaskets — failing seals can double consumption.
- Keep the freezer 75% full (cold mass holds temp better when door opens).
