Check for duct leaks.
Leaks rob your home of heat in the winter and air conditioning in the summer and are one of the largest energy wasters in the average home.
Chargers, computers, and other electronics that are plugged in will continue to draw energy even if they’re not in use.
Check your fridge’s temperature.
According to the DOE, fresh food compartments should be between 37 to 40 degrees and the freezer at five degrees.
Keep your freezer full.
Solids retain low temperatures better than air. If you don't want to stock up on frozen goods, place half-filled gallon jugs of water in the freezer.
Run a full dishwasher.
Waiting until your dishwasher is full to run it can help you save on water. You can also skip the heat dry cycle to shorten run time.
