Follow these simple steps to find out exactly how much your appliances cost to run:
Devices on standby can consume 5-10% of your home's energy. Unplug chargers, TVs, and gaming consoles when not in use.
LED bulbs use up to 80% less energy than incandescent bulbs and last 25 times longer. Replace your most-used bulbs first.
Set your thermostat to 68°F in winter and 78°F in summer. Each degree can save 3-5% on heating and cooling costs.
Energy Star certified appliances use 10-50% less energy than standard models. Look for the label when replacing old units.
Nearly 90% of a washing machine's energy use goes to heating water. Switch to cold water washes and save on every load.
Smart power strips cut power to devices that enter standby mode. One click turns off your entire entertainment center.
