Use a heavy-duty, clear plastic sheet on a frame or tape clear plastic film to the inside of your window frames during the cold winter months. Make sure the plastic is sealed tightly to the frame to help reduce drafts.
Install tight-fitting, insulating drapes or shades on windows that still feel drafty.
Seasonal LED lights use up to 90 percent less electricity and last up to 10 times longer than traditional incandescent holiday lights. The same LED string could still be in use 40 Christmases from now.
LED holiday lights have other advantages, too:
Safer: LEDs are much cooler than incandescent lights, reducing the risk of fire or burnt fingers.
Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.
Easier to Install: Up to 25 strings of LEDs can be connected end-to-end without overloading a wall socket.
Use fans and ventilation strategies to cool your home
Use a fan. Ceiling fans can provide the equivalent of four degrees of cooling comfort.
Turn off ceiling fans when you leave the room. Remember that fans cool people — not rooms — by creating a wind chill effect.
When you shower or take a bath, use the bathroom fan to remove the heat and humidity from your home. Your laundry room might also benefit from spot ventilation. Make sure bathroom and kitchen fans are vented to the outside (not just to the attic).
On hot days, avoid using the oven. Cook on the stove, use a microwave, or grill outside.
Install efficient LED lighting that is much cooler than incandescent lighting. Only about 10–15 percent of the electricity that incandescent bulbs consume results in light — the rest is turned into heat.
Wash only full loads of dishes and clothes. Consider air drying both dishes and clothing.
