Simple Steps To Reduce Your Energy Use and Costs

  • Weatherization

    How-to videos
    • Apply a window weatherization kit
    • Change your furnace filter
    • Seal your attic access door
    • Seal attic bypass leaks
    • Insulate the rim joist
    • Weatherize safely

    Save with this simple reminder

    Air leaks are the biggest energy wasters in the home. The good news is it doesn’t cost much to seal them. Caulk, weather strip, and/or insulate around:

    • Entrance doors.
    • Electrical outlets and switch plates on exterior walls.
    • Bathroom and kitchen exhaust fans.
    • Exterior hose connections, such as dryer exhausts.
    • The areas where ductwork, electrical wiring, or plumbing extends through floors, ceilings, or exterior walls.
    • Warm-air registers and water-heater and furnace flues.
    • New and replacement windows. Replace cracked caulk on existing windows.

  • Heating/Cooling

    Save with these simple tips

    • Have your heating and cooling systems serviced every year for peak operational efficiency and safety.
    • Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer. You save 3 percent on the day’s heating or cooling costs by setting your thermostat back one degree (higher for cooling, lower for heating) for that 24-hour period. Maintain those settings and you save 3 percent all season!
    • Clean or replace heating and cooling filters once a month or as needed. If your filter is in a cardboard frame, it needs to be replaced monthly during the heating season. If your system doubles as a central air-conditioning system, also clean or replace the filter monthly while the cooling system is in use.
    • Clean air registers, baseboard heaters, and radiators as needed.
    • Make sure air returns and registers are not blocked by furniture, carpeting, or drapes.
    • Bleed trapped air from hot-water radiators once or twice a season. If in doubt about how to perform this task, call a professional.
    • Use kitchen, bath, and other ventilating fans wisely, turning fans off as soon as they have done the job.
    • Depending on where they are used, a ventilating fan will complete 8 to 15 air changes per hour (ACH) and if left running when not needed, it will cause your HVAC system to run more often.
    • During the heating season, keep the draperies and blinds on your south-facing windows open during the day to allow sunlight and heat to enter your home.
    • Close drapes at night to help reduce heat loss.
    • During the cooling season, keep the window coverings closed during the day to prevent the sun from heating your home.
    • Close off unoccupied rooms.

  • Water Heating

    Save with these simple tips

    • Install low-flow showerheads and faucet aerators that will help you use less water.
    • Insulate long runs of hot-water supply pipes, especially sections that pass through unheated spaces.
    • Repair or replace leaky faucets. The drips add up fast and represent dollars going down the drain.
      Fact: A hot water faucet that leaks one drop per second wastes more than 2,300 gallons of hot water per year, which could cost as much as $36. The replacement washers needed to repair a leaky faucet cost only a few cents.
    • Lower the water heater thermostat to 120° F. or talk to your plumber about raising the temperature and install a cold-water mixing valve to the line. A properly installed mixing valve on an 80-gallon water heater increases usable hot water to 120 gallons and adjusts the temperature to a lower (safe) level as it leaves the tank.

  • Lighting

    Save with these simple tips

    • Use task lighting to illuminate work and leisure activities. This lets you reduce your overall room lighting levels.
    • Use energy-efficient compact fluorescent bulbs—especially in fixtures that operate more than two hours a day. They cost more initially but use 75 percent less electricity and last about ten times longer than incandescent bulbs.
    • Open shades and blinds to take advantage of natural light.
    • Select bulbs carefully. Look for the highest lumens at the lowest wattage. Wattage is the power needed to make a bulb work. Lumens measure brightness.
    • Keep light fixtures clean to gain the most illumination.

  • Kitchen

    Save with these simple tips

    Food storage

    • Think before you open the fridge. Try not to "window shop" with the door open or you'll lose your cool air causing the motor to run more often.
    • Test the tightness of the door seal on refrigerators and freezers. If the seal doesn't tightly hold a dollar bill when the door is closed, it's probably time to adjust or replace the gasket.
    • Replace old refrigerators. The best modern models use less than half the energy than models manufactured between 1993 and 2000.
    • For greatest efficiency set refrigerator temperatures at 40º F. and freezers at 0º F.


    • Use small appliances such as crockpots, electric frying pans, toaster ovens, and microwave ovens to save energy when cooking.
    • Use your oven instead of your cook top to cut cooking costs. Surface units heat continuously, but an insulated oven normally heats one-third of the time it's in use.
    • Don't peek. Cooking temperatures can drop as much as 50º every time the oven door is opened, causing the oven to reheat.
    • Use the oven's self-cleaning cycle only for big cleaning jobs. Start the cycle while the oven is still hot from baking.

  • Laundry

    Save with these simple tips

    • Wash with cold water whenever possible.
    • Wash and dry full loads to maximize efficiency.
    • Don't overload your dryer. Overloaded dryers will need to run longer and use more energy, cause clothes to wrinkle so they may need to be ironed, and cause clothes to wear out more quickly.
    • Use front-load washing machines for maximum efficiency. They use less than half the water and electricity of standard top loaders and require much less soap.
    • Always adjust the water level to fit load size. Overloaded washers don't clean clothes as effectively so they may need to be rewashed.
    • Clean the lint filter after each drying cycle to maintain dryer efficiency.
