Insulate outlets and light switches

Outlets and light switches in the walls that separate your home from the outdoors are often overlooked sources of heating or cooling loss. Insulating these areas using foam gaskets - little, inexpensive foam pads made to fill the gap behind the switch cover - can help reduce drafts.

You can save up to $10 per year when you insulate five outlets.
