Switch your lighting.
ENERGY STAR qualified LED bulbs can have last about 25,000 hours or more, 25 times longer than incandescent light bulbs and 2.5 times longer than compact fluorescent light (CFL) bulbs. Commit to replacing the bulbs in your home's five most frequently-used light fixtures for LED bulbs and you can save more than $65-$100 annually in energy costs. Try to get into the habit of switching off the lights when you leave the room as well.
Complete a home energy repair.
Don't put off your home maintenance any longer. Whether its sealing drafts and cold spots or installing a smart thermostat, anything makes a difference in energy savings. Just spending a little on a new HVAC filter will go a long way toward maintaining efficiency and decreasing your energy bills.
Use your fans.
Bathroom exhaust fans can help control the moisture in your home, save energy and keep you comfortable. During the summer, setting your ceiling fan in the counterclockwise direction will allow you to raise your thermostat settings by about 4 degrees with no reduction in comfort.
While you’re dusting your TV, computer, gaming equipment, and other home electronics, take a look at how they’re plugged in. Unplug devices that are not in use or invest in an advanced smart power strip, which automatically cuts electricity to any idle equipment you choose.
