Refrigerator
Your refrigerator uses about 1,000 watts of power per hour, costing 10 cents per hour. While you can’t unplug your refrigerator to reduce energy usage, you can take other steps.
Keep foods covered in the refrigerator, as the moisture released by foods makes the compressor have to work harder. If you’re in the market for a new refrigerator, make sure you get one that’s the right size for your family — a full refrigerator uses less energy than one that’s half-empty.
