1. Need a new refrigerator? You could save $100 a year on your energy bill by replacing an older model with a new, Energy Star-qualified appliance. You could save $200 a year if your old refrigerator is from the1970s, Energy Star says.
2. Insulating your attic and the walls, and floors adjacent to an unheated garage or basement, can make a dent in your heating and cooling bills.
3. Unplug the TV. Electronics like TVs, speakers, gaming consoles, computers and even phone charges continue to use energy, even when they’re turned off. Unplug them before you go to bed.
4. Dim the lights. Dimmer switches control how much light you use. A switch with a timer can turn lights on and off at set times. A light fixture with a motion sensor will turn itself off when a room is empty. All of that adds up to energy savings.
5. Switch to LED lights. They use 90 percent less energy than incandescent light bulbs. Come on! It’s time!
