Cut Energy Usage!

Saving money by cutting energy usage at home is easier than you think, especially with these tips from Illinois Energy and ENERGY STAR®. Following these simple suggestions can save you as much as 10%-25% on your energy bill. 

Turn on Savings

  • Turn off the lights when you're not in the room. Don’t forget to turn off the TV, the computer and the stereo when you're not using them.
  • Keep your windows and doors closed when heating and air conditioning systems are on.
  • In the winter, open the curtains and roll up the blinds on sunny days to help warm the room. In the summer, pull down the shades and close the curtains to keep the sun out, helping to keep the room cooler during the day.
  • Clean your refrigerator coils and make sure the temperature is set correctly. Fresh foods keep at 37°  to 42° F; frozen foods at 0°  to 5° F.
  • Only do full loads in the washer and the dryer. Wash in cold water. Keep the dryer lint trap clean. Line-dry your clothes.
  • Set the water heater temperature to 120° F or lower.
  • Wash only full loads in your dishwasher. Let dishes air-dry.

Easy Fixes That Are Easy on Your Pocketbook

  • Install compact fluorescent light bulbs. ENERGY STAR-qualified CFLs use about 75% less energy, give off less heat and last up to 10 times longer. An ENERGY STAR-qualified CFL can save you about $30 or more in electricity costs over its lifetime.
  • Seal air leaks with weather stripping and caulk.
  • Fix any leaky faucets. They waste water and cost you money.
  • Clean or change your HVAC system air filter once a month.
  • Install an ENERGY STAR-qualified programmable thermostat. With proper use, these can save you about $150 every year in energy costs.

Save More With Smart Investments

  • Stop energy waste. The ducts that move air to and from a forced air furnace, central air conditioner or heat pump are often poorly sealed. Seal and insulate those ducts to improve the efficiency of your heating and cooling system.
  • Make sure your walls and attic have the right amount of insulation.
  • Replace your home's old, leaky windows with new high-performance windows

Save Energy and Money with ENERGY STAR-Rated Appliances

  • Consider replacing your old HVAC equipment with a unit that has earned the ENERGY STAR label. Replacing your old heating and cooling equipment with ENERGY STAR-qualified equipment and sealing your ducts can cut your energy bill by as much as $180.
  • Remember that bigger isn't always better. If your HVAC unit is too big for the size of your home, you may be less comfortable and receive higher energy bills.
  • Purchase a new energy-efficient refrigerator. Models purchased before 1993 use twice as much energy as today's ENERGY STAR-labeled models.
