The energy you use is critical for the comfort, convenience and safety of your family, but you still have to pay for it. Fortunately, there are a variety of simple, low-cost measures you can take to optimize your energy dollars while still maintaining your comfortable lifestyle.

1. Focus on lighting.

Replace conventional incandescent bulbs with ENERGY STAR®-certified LEDs. These bulbs are at least 75% more efficient and last much longer.

2. Adjust the thermostat

Raise or lower temperatures (depending on the season) at night and when you're away from home. Wi-Fi-enabled smart thermostats provide advanced features, such as remote control and self-programming.

3. Plug smarter

Many electronic devices continue to use power when they're turned off or not in use. Unplug battery chargers and any other devices when it's convenient. Plug devices into an advanced power strip. They automatically shut off devices when they're not in use.

4. Use window treatments

Close window treatments on south-facing windows in summer to keep out solar heat during the day. In the winter, open curtains or drapes during the day to let in the warmth of the sun; close them at night to retain heat.

5. Seal air leaks

Do you have old, broken caulk around the outside of your windows or gaps around exterior doors? Seal those leaks by caulking windows and placing weatherstripping around the inside of door frames. See Air Sealing Your Home from the U.S. Department of Energy for more information.
