Lower the thermostat a few degrees and dress warmly, or use additional blankets to stay comfortable.
Close the fireplace damper when not in use to avoid losing heat through the chimney.
Use dampers on the ductwork to balance the airflow in a home if one room is colder or warmer than another.
Do not use a wood-burning fireplace for supplemental heating, as it pulls hot air out of a home through the chimney to fuel the fire.
Seal windows and external doors with weatherstripping
Avoid washing and drying clothing or running the dishwasher during the coldest parts of the day — typically late night and early morning.
Switch desktop computers and monitors to sleep mode when not in use, and shut off computer monitors when not in use. Do not just turn off electronics like televisions, DVD and Blu-ray players or cable boxes when not in use; unplug them if possible.
