1). Cut down on energy leaks.
- Shut off the light behind you.
- Unplug electronics that aren’t being used (e.g., cell phone chargers, small appliances, or power strips that provide power for many devices).
Note: TVs, DVD players, digital photo frames, and other appliances use more energy than you realize. Unplugging an appliance is best because certain appliances use energy even if they are turned off. Consult with roommates or coworkers before unplugging a shared appliance.
2). Close blinds, storm windows, or shades during the day.
- The sun can heat up a room very quickly.
- Keeping the sun from shining into windows will cut down on cooling costs.
Note: Many stores sell thermal insulated curtains designed to protect against the heat.
3). Use air conditioning efficiently.
Note: The smaller the difference between the outdoor and indoor temperatures, the smaller your bill. Do not place appliances that give off heat, such as lamps or TVs, near an air conditioner’s thermostat.
4). Use fans instead of air conditioning.
- Circulation is important to using less air conditioning during the summer.
- Cool down the house early in the morning by placing a box fan in the window and opening up another window at the opposite end of the house, in addition to turning on ceiling fans. Box fans help cool air come inside.
Note: Most central air conditioners will also have internal fans to help circulate the air in your house while reducing the need to use the air conditioner. Turn the fan on “auto.” Using fans at night will help a natural breeze cool down your house. This will work if the temperature drops at night. Turn a fan directly towards yourself or guests.
5). Avoid heat build-up in your home.
- Use heavy appliances (e.g., washer, dryer, air conditioning, computers) in the early morning or late night.
- On hot days, avoid using the oven; cook on the stove, use a microwave, or grill outside.
- Wash only full loads of dishes and/or clothes. Consider air drying both dishes and/or clothing.
- Take short showers instead of baths.
Note: Minimize activities that generate a lot of heat, such as running a computer, burning open flames, running a dishwasher, and using hot device such as curling irons or hair dryers. Wait until after 6 p.m. to cook, do laundry, or wash dishes on days the temperature is more than 90 degrees.
