Apply caulk to seal off leaks in and out of windows. Caulk is cheap and can add up big savings on your energy bill.
2. Close off unused rooms.
Keeping doors closed won’t just prevent cold air from moving into the rest of the house — it will help keep the heat you’ve generated.
3. Change your sheets.

4. Set your ceiling fans to rotate clockwise.
Whether you know it or not, your ceiling fan needs to be changed according to the season. Setting a fan to rotate clockwise in the winter at a lower speed, can drive warm air down towards you.
5. Open or close curtains.
