Are you making a resolution to go on a diet in January? Open a savings account? Join a gym?

Here’s a resolution you might be able to keep in 2016: Do one thing a month that will make your home more energy efficient. Here are 12 easy ideas:

January:
Get in the habit of turning down your thermostat by about 10 degrees before your family turns in for the night or leaves in the morning. You can save as much as 1 percent a year in energy bills for every degree you lower the heat for eight consecutive hours.

February:
Pull your refrigerator away from the wall and vacuum or dust its condenser and coils. Clean coils prevent your fridge’s working parts from heating up.

March:
Get an annual inspection of your air-conditioning system. It can keep your central A/C running efficiently all summer.

April:
Hire a licensed electrician to inspect your home’s electrical wiring system—not every year, but at least once a decade.

May:
Wash your windows, inside and out, and open the drapes. The sun can’t warm and brighten your rooms if it can’t find its way through grimy windows.

June:
Trim your hedges. Overgrown shrubs and trees can shade your windows too much and keep the sunlight from warming your home come winter.

July:
Grill your dinner outside and serve fresh salads. Giving your stovetop and oven a rest gives your A/C a break on hot days.

August:
Run your clothes washer, dryer and dishwasher after dark. That keeps heat and humidity out of the air and saves on energy costs.

September:
Get the heating and air conditioning tech back to your house for a heating inspection. A tune-up can save you as much as 5 percent on your heating bill.

October:
Close off your masonry fireplace, and resolve not to use it anymore. Every time you use it, it sends your home’s heated air up the chimney.

November:
Seal air leaks around windows, doors and other openings with caulk and weather-stripping.

December:
Replace your old holiday lights with LED fixtures, which will last years longer and use far less energy.
