Winter is coming! As temperatures drop and trees change color — and people around the country prepare their homes for the cold weather ahead — the Department of Energy has got you covered with tips for saving energy and keeping cozy all winter long.

• Did you know space heating is the largest energy expense in the average U.S. home? Our Home Heating Infographic has lots of great information about how to save money while still keeping your home warm — such as installing a programmable thermostat, which can help save an estimated 10 percent per year. And our Tips for Cozying up to Winter Weather (Part 1 and Part 2) give even more great advice for preparing. For example, did you know that cleaning out your gutters can lead to energy savings?
