Save a bundle of energy


  • Turning off lights not in use is the cheapest and most effective way to save.
  • Replace old light bulbs with ENERGY STAR® qualified LED’s. They last up to 10 times longer and use up to 90 percent less energy compared to incandescent bulbs. Earn instant markdowns with our lighting discount program.
  • Use light timers to manage energy use for extended periods of time. Install motion-sensor lights for porches, patios and outside areas.
  • Replace your home’s five most-frequently used light fixtures with models bearing the ENERGY STAR mark. You’ll save $70 on average per year in energy costs.

Heating & Cooling

  • ENERGY STAR smart thermostats can save you up to $145 a year on heating and cooling costs.
  • In summer, set your thermostat to 78 degrees or higher and 85 degrees or higher when you leave home for four-plus hours. During winter, set it no higher than 68 degrees when home and 60 degrees when away or sleeping.
  • Change your heating and cooling system’s filter every 30 days and schedule a qualified contractor to perform an annual check-up.
  • Portable and ceiling fans are an efficient alternative to air conditioning. On the other end of the spectrum, avoid using energy-hogging portable electric heaters.
  • Using window coverings during the day will keep your home cooler, especially where direct sunlight comes in.
  • Set your water heater’s temperature to no greater than 120 degrees.

Appliances & Devices

  • Vacuum under and behind your freezer and refrigerator to maintain their efficiency.
  • When possible, unplug electronics and small appliances when not in use. 
  • Run dishwashers only when they are full and let dishes air dry.

Air Sealing

  • Weatherstrip doors and windows and reduce the amount of air loss from your home. Be sure to pick the right type for your project.
  • Caulk is a good choice for sealing up gaps, holes and cracks around doors, windows, walls and vents. There are a few types but silicone is the most versatile and lasts the longest.
  • Ensure that your attic’s insulation is rated at least R30. Exterior walls in your home should be insulated to R11.
  • Depending on the age, construction and location of your home, consider insulating basement walls, crawl spaces, pipes and ducts that run through unheated areas.
