Energy Conservation - Large Appliances
Make Your Refrigerator Purr: Gently brush away dirt and dust from the exposed coils at the back of your refrigerator, and make sure it has breathing room. Also, check the seals on the doors to make sure they are tight. If you can put a dollar bill in the door and pull it out after it is closed, you probably need new seals. If your fridge is more than ten years old, it may pay to get a new one.
Cost: Free to clean; new seals vary.
Clothes Line or Rack:Investing a few dollars in a clothes line or clothes-drying rack can cut your utility bill by as much as 20%. Check with your homeowners' association before installing. And remember, the lint that you collect from your dryer after every cycle used to be in your clothes! A clothes line or drying rack will keep your clothes more intact and help them last longer.
Cost: Less than $15
Cost: $500 or more
Cost $500 to $1500
Energy Star Central Heat Pump: A heat pump can trim the amount of electricity you use for heating as much as 30% to 40%. If you use electricity to heat your home, consider installing an energy-efficient heat pump system. Heat pumps are the most efficient form of electric heating in moderate climates, providing three times more heating than the equivalent amount of energy they consume in electricity by collecting heat from the air, water, or ground outside your home and concentrating it for use inside. Heat pumps do double-duty as a central air-conditioner. They can also cool your home by collecting the heat inside your house and effectively pumping it outside.
Cost: $100 to $500
Cost: $300 to $700
Energy Efficient Central Air Conditioner: Qualifying Central air conditioners must be listed by the Air-Conditioning and Refrigeration Institute (ARI) and must have an ARI reference number obtained from the licensed contractor who installs the unit.
