It doesn’t take much time or money to reap the benefits of a more energy-efficient home. Here are seven ways you can save energy with little effort and less money:
1. Caulk and weather-strip around windows and doors, where even the tiniest gaps or cracks can let your heated or air-conditioned air outside and the outdoor air in. Using materials you can pick up at a hardware or home store, you can plug these energy-wasting leaks and save up to 20 percent on heating and cooling bills. An extra benefit: Your home will feel more comfortable because it will be less drafty and the air will be conditioned more evenly.
2. Turn off lights, fans and the TV when you leave the room, and unplug everything you can before you leave the house for an extended time like a weekend away. Turning off your electric devices saves energy, and unplugging them—even if they were already turned off—saves even more because it prevents them from using “standby power.”
3. Check your attic insulation. You might have plenty up there, but if it’s sagging away from the surfaces it’s supposed to touch, it’s not doing you any good. A properly insulated attic can save you up to 20 percent on heating and cooling bills.
4. Wash your clothes in cold water; they’ll get just as clean as if you use warm water. Also, select the “energy saver” and “no heated dry” options on your dishwasher.
5. Change any remaining incandescent light bulbs in table lamps or overhead light fixtures to compact fluorescent bulbs. CFLs use at least 30 percent less energy than traditional bulbs.
6. Install a programmable thermostat and tell it to turn the temperature down a few degrees in the winter and up a bit in the summer in the morning after everyone leaves the house for the day. You could save 10 percent on heating and cooling bills.
7. When it’s time to replace an appliance, buy a new one with the Energy Star label. Savings: up to 30 percent on the electricity it takes to run the appliance.
