Frequently Asked Questions
How much electricity does a refrigerator use?
A modern full-size refrigerator (18–25 cu ft) uses 300–800 kWh per year, with an average around 450–500 kWh/year for newer ENERGY STAR models. Older fridges (pre-2000) can use 1,200–2,000 kWh/year — up to 4× more than modern units. The EnergyGuide label on your fridge shows the estimated annual kWh.
Where do I find my fridge's kWh rating?
Look for the yellow EnergyGuide label on the interior or exterior of the fridge. It shows an estimated kWh/year figure. You can also find it on the manufacturer's website by searching the model number. Alternatively, use a Kill A Watt meter to measure actual consumption over 24 hours, then multiply by 365.
Does the temperature setting affect electricity use?
Yes. The FDA recommends 35–38°F for the fridge and 0°F for the freezer. Setting 5°F colder than needed increases energy use by about 25%. Keeping your fridge between 35–38°F (not 32°F) saves energy without food safety risk. Each degree colder than optimal adds roughly 5% to running cost.
Is it worth replacing an old refrigerator?
Often yes. A 1990s fridge might cost $180–$250/year to run vs. $50–$70 for a new ENERGY STAR model — a $150/year saving. At that rate, a $600 new fridge pays for itself in 4 years, then saves for 15+ more years. Check whether your utility offers a rebate for recycling the old appliance (many pay $50–$150).
How does fridge size affect electricity use?
Counterintuitively, larger fridges aren't always less efficient per cubic foot. A 20 cu ft ENERGY STAR fridge might use 400 kWh/year; a 25 cu ft model 500 kWh/year. Side-by-side models with ice makers use more (600–800 kWh) than top-freezer models. French door models vary widely by brand.
