1. Thermostat.
In most homes, the largest portion of the energy bill goes toward heating and cooling. Setting back your thermostat by 7 to 10 degrees for eight hours a day can save you up to 10 percent a year on heating and cooling. Try turning your thermostat down some when no one is home, bumping the temperature back up when you return. If you’re used to a warmer house, it may mean throwing on a sweater or pair of slippers. Keep in mind this tactic is not as effective for some homes with radiant heat systems.
