The way your home uses energy changes with the seasons, making the winter a good time for an energy audit.

Check for air leaks

Air leaks are a major cause of energy waste. Check for air leaks by shutting doors and windows on a piece of paper. Try to pull the paper through. If it doesn’t tear, then you may want to consider weather-stripping. Measure the perimeter of windows and doors, then add 10% to determine how much weather-stripping material you need.

If you use your heater frequently then you may want to change filters every month during winter. Clogged filters make your heater work harder and use more energy.

Switch light bulbs.

Switch light bulbs says you can save $75 a year by replacing your home’s 5 most frequently used lights. Use a lighting usage calculator to determine the energy cost of traditional incandescent bulbs versus more energy efficient options like CFL lights. Or, you can even switch to dimmers. The days are a lot shorter now, which means even energy efficient lights are working overtime. Install dimmer switches and you can use less energy to light your home without having to cook dinner in the dark.

Program your thermostat, correctly.

Turning your thermostat down 10 to 15 degrees while you sleep for 8 hours can save 5 – 15 % a year on heating. However, if you live in a mild climate where you don’t necessarily need the thermostat every day, then programming it to go on at certain hours could actually increase your energy usage.

Standby may be convenient but it means appliances and electronics are sucking up valuable energy even when you’re not using them.
