Start with the small things
There are a lot of simple things you can do to reduce your energy use, and small things can add up to make a big difference. Small things like replacing incandescent light bulbs with compact fluorescent light bulbs, washing clothes in cold water, and caulking and weather sealing your home can add up to big savings.
Evaluate your home’s energy use
You can audit your home’s energy use by using an on-line home energy calculator. ENERGY STAR’s Home Energy Yardstick 
allows you to enter information specific to your home, and then advises you on home energy improvements that should save you money.
Consider home improvements that you can do yourself

The bulletins can be freely downloaded at their website . Printed copies can be purchased by calling 800-287-0274 (in Maine) or 207-581-3792.
