Spend Smart, Save Smart Tips

Ten Tips for Cutting Energy Costs

  • Fix air leaks around windows, doors, and electrical outlets. Use foam inserts, weather stripping, and caulk.
  • Install storm windows and doors, or put up plastic sheeting to reduce heat loss.
  • Turn the thermostat down at night or while no one is home. You can reduce your heating bill by as much as five percent.
  • Insulate attics, exterior walls, under floors, heat ducts and hot water pipes.
  • Replace incandescent light bulbs with compact florescent light bulbs (CFL) or wherever possible. By replacing just five, you can save about $60 per year.
  • Turn off lights when no one is in the room.
  • Take shorter showers.
  • Install an Energy Star qualified programmable thermostat – set to lower the heat when you’re gone and while sleeping.
  • Close fireplace damper when not in use to prevent cold air from entering the house.
  • Unplug DVD players, battery chargers, TVs and computers when not in use. They use energy constantly.
