Energy Saving Tips

Appliances and Electronics:

  • Unplug any unused appliances and electronics to reduce phantom load. To learn more about phantom load, visit
  • Use Advanced Power Strips, a new technology that can help reduce phantom load by turning devices on and off automatically.
  • Use ENERGY STAR® certified appliances.
  • Use ENERGY STAR® certified lighting.
  • Unplug your cell phone chargers when not in use.
  • Unplug your game systems when not in use. Some game systems use as much power as a refrigerator.
  • Use a DVD player for watching videos instead of gaming systems – most DVD players use half the power of the gaming system.


  • Install programmable thermostats.
  • Turn your thermostat down 5-10 degrees at night. You’ll save 5 to 10 percent on your heating bill.
  • Don’t set thermostats higher than you want the temperature of your home to be, it won’t heat your home any faster and will keep your furnace running longer than necessary.
  • Vacuum registers and vents regularly and don’t let furniture or draperies block air flow.
  • Keep curtains and blinds closed at night; this will help keep cold air out. Remember to open them during the day to allow the sun to come in and warm things up again.
  • Add rugs to hard surface floors to keep feet warm.
  • Seal doors and windows in the winter. This is a low cost investment in weatherization that will reduce heating costs by 2 to 3 times that investment.

Hot Water:

  • Install water saving showerheads.
  • Set water heater at 120 degrees.
  • Fix leaky faucets.
  • Take short showers, not baths. A five minute shower uses 7.5 gallons of water and a bathtub uses up to 20 gallons.


  • Use smaller kitchen appliances when possible. Microwaves, toaster ovens, and slow cookers use 75 percent less energy than large electric ovens.
  • Vacuum refrigerator coils two times per year.
  • Don’t leave the refrigerator door open. Every time it’s opened, 30 percent of cooling air can escape.
  • Keep refrigerator at 36-38 degrees and freezer at 0-5 degrees.
  • Keep your refrigerator and freezer full, but don’t overload them so cold air can circulate.
  • Use the self-cleaning feature on the oven just after use to reduce warm-up time.
  • Run dishwasher with only full loads and use the air-dry cycle. If your dishwasher has a booster for a water heater, use it. This will heat water to the manufacturer’s recommendations (140 degrees) while allowing you to set the temperature lower on your water heater.
  • Unplug or get rid of your 2nd refrigerator or freezer. It could be costing you up to $150 per year. NHSaves can help you dispose of your appliance properly. When you purchase a new refrigerator or freezer, make sure it is ENERGY STAR certified.


  • Wash only full loads of clothes.
  • Use hot water for only very dirty loads. Up to 90 percent of the cost of washing clothes comes from heating the water.
  • Clean the lint screen on your dryer after every load.
  • Remove clothes from dryer while still damp and hang them up.
  • Dry one load of clothes immediately after another. This will minimize heat loss and reduce warming up and drying times.


  • Switch to CFL or LED bulbs. Each replacement bulb can save you more than $70 in its lifetime.
  • Buy the right light bulb for the lighting fixture.
  • Clean light fixtures regularly. Dust can block 50 percent of light output.
  • Use a single bulb in a multi-socket fixture – check the max wattage the fixture allows.
  • Turn off lights when not in use.
  • Add an occupancy sensor that will automatically turn on lights when someone enters the room and shut off the lights after people have left.
