Saving Energy And Money In Y
he major energy users in your home—heating system, air conditioning, electric water heater, refrigerator, dryer, lighting—all contribute to your overall electric utility bill. This brochure offers tips to help you use
them more efficiently, lower your energy use and save
money on your monthly electric bill.
Caution: Some people, including the elderly, infants and
persons with circulatory problems, may require higher
indoor temperatures (above 65 degrees F. at all times)
to avoid health problems. Please seek the advice of your
physician regarding winter and summer thermostat settings in your home.

Your Home
Your Heating System
1. Keep your heating equipment well tuned with periodic
maintenance by a professional service representative.
2. Use kitchen, bath and other ventilating fans sparingly.
You can blow away a houseful of heat in just two to
three hours using ventilating fans. Turn them off
when their job is complete.
3. Set your thermostat at 68 degrees F. during the day
and 60 degrees F. at night. You can save 3 percent on
your heating costs for every degree you reduce the
temperature below 70 degrees F. for the entire heating season. Special Advice to Heat Pump Owners: Heat
pumps need to stay at a constant setting, unless you
have a programmable electronic heat pump thermostat with adaptive recovery. Check with your heating
or air conditioning contractor to determine the type
of thermostat you have.
4. Turn down your thermostat at night or when you’re
away for more than four hours during the day. Do not
turn off your heating system entirely as this may cause
pipes to freeze.
5. If you have a simple open-masonry fireplace, consider
installing a glass screen, a convective grate, a radiant
grate or a fireplace insert. They’ll help cut down on
the loss of warm air through the fireplace chimney.
6. Maintain proper air circulation. Keep heating supply
registers and cold-air return registers clear of draperies
and furniture.
7. Clean or replace the filter in your forced-air heating
system each month. Foam filters can be rinsed with
water, but be sure they are dry before replacing.
Fiberglass filters need to be replaced periodically.
8. Keep draperies and shades open during the day to let
the sunshine in; close them at night.
9. Check the duct work for air leaks about once a year if
you have a forced-air heating system. To do this, feel
around the duct joints for escaping air when the fan is
on. Relatively small leaks can be easily repaired by covering holes or cracks with duct tape. More stubborn
problems may require caulking as well as taping.
10. Dust or vacuum radiator surfaces frequently. Dust and
grime impede the flow of heat.
11. Don’t place lamps or television sets near your thermostat. Heat from these appliances is sensed by the thermostat and could cause your furnace to shut off sooner than is needed for adequate warmth.
12. Dress warmly. The human body gives off heat—
about 390 BTUs per hour for a man, and about 330
BTUs per hour for a woman. Dressing wisely can
help you retain natural heat. Wear closely woven
fabrics, which add at least a half degree in warmth.
Slacks are at least a degree warmer than skirts; a
light, long-sleeved sweater equals almost 2 degrees
in added warmth; a heavy long-sleeved sweater adds
about 3.7 degrees; and two lightweight sweaters
add about 5 degrees in warmth because the air
between them serves as insulation to keep in more
body heat.
Your Cooling System
13. Keep your cooling system well tuned with periodic
maintenance by a professional service representative.
Ask your service representative how the energy efficiency of the system may be increased.
14. When selecting a central air conditioning unit, be sure
to choose one with the proper capacity and highest
15. Choose a central air conditioning unit or room air conditioning unit that uses a minimal amount of electricity to complete its task. High Seasonal Energy Efficiency
Ratios (SEERs)—such as 13.0 SEER and above—correspond with greater efficiency. Energy Efficiency Ratios
(EERs) provide the same guidance for room air conditioning units.
16. Install a whole-house ventilating fan in your attic or in
an upstairs window to help air circulate in your home.
Although not a replacement for a central air conditioning system, a fan is an effective way to stay comfortable on milder days.
17. Set your thermostat at 78 degrees F., a reasonably
comfortable and energy efficient indoor temperature.
18. Don’t set your thermostat at a colder setting than normal when you turn your air conditioner on. It will not
cool faster, but it will cool to a lower temperature
than you need and use more energy.
19. Consider using a ceiling fan with your window air conditioner to spread the cooled air to other rooms. But
be sure the air conditioner is large enough to help
cool the additional space.
20. Don’t place lamps or television sets near your thermostat. Heat from these appliances is sensed by the thermostat and could cause your system to run longer
than necessary.
21. Clean or replace air conditioning filters. Dirty air filters
should be cleaned or replaced every month. Foam filters can be rinsed with water and wrung dry.
Fiberglass filters need to be replaced.
22. No matter what kind of central air conditioning system you have, clean the outside condenser coil once a
year. To clean, turn off the unit and spray the coils
with water at a low pressure. (High water pressure
may bend the fins.) Try to spray from the top of the
unit down and outward.
23. Use duct tape to seal the cracks between each section
of an air duct on your central air conditioning or
forced-heating system.
Other Cooling Tips
24. Keep out the daytime sun with vertical louvers or
awnings on the outside of your windows. Draw any
draperies, blinds and shades.
25. Keep lights low or off when not needed. Electric lights
generate heat and add to the load on your air conditioner.
26. Plant shade trees strategically around your home.
Properly selected and planted shade trees can save up
to $80 annually on the average electric utility bill.
27. Cook and use other heat-generating appliances in the
early morning and late evening hours whenever possible.
28. Use window or whole-house ventilating fans to cool
your home.
29. Use vents and exhaust fans to pull heat and moisture
from the attic, kitchen, bath and laundry directly to
the outside if you don’t have air conditioning.
Sealing Air Leaks
30. Insulate your attic floor or top-floor ceiling to a minimum of R-49 for these spaces. R-values or numbers
indicate the resistance of an insulation material to
heat flow. The higher the R-number, the more effective the insulating capability. R-values appear on the
packages of insulation materials.
31. Don’t insulate over eave vents or on top of recessed
lighting fixtures or other heat producing equipment
on the attic floor. Also, keep insulation at least 3 inches away from the sides of these types of fixtures.
32. Insulate heating and cooling ducts in unheated or
uncooled areas.
33. Don’t let air seep into your home through the attic
access door. Check the door to make sure it is well
insulated and weather stripped—otherwise, you’ll be
wasting fuel to heat or cool the attic.
34. Test your windows and doors for air tightness. Add
weather stripping and caulk where necessary. Its low
cost and can save you 10 percent or more in annual
energy costs.
35. Install storm windows. Combination screen and
storm windows (triple-track glass combination) are
the most convenient because they can be opened
easily when there’s no need to run heating or cooling equipment.
Hot Water Heater
36. Buy a high-efficiency water heater. When you need
a new water heater, purchase a unit with a high
Energy Factor (EF) rating. EF ratings—such as those
of .91 and above—correspond with greater efficiency. The higher the rating, the more efficiently the
unit will operate.
37. Turn down the water heater temperature dial to
120 degrees F. or less, or to the “warm” setting. If
you have a dishwasher, be sure to check your
manufacturer’s instructions for minimum water
38. Insulate the outside of your water heater with an
insulation blanket to reduce heat loss and save $10 to
$20 a year.
Kitchen Energy Savers
39. Use cold water rather than hot to operate your food disposal. Cold water also helps get rid of grease by solidifying it, so it can then be ground up and washed away.
40. Install an aerator in your kitchen sink faucet.
41. Never boil water in an uncovered pan. Water will
come to a boil faster and use less energy in a kettle or
covered pan.
42. Keep range-top burners and reflectors clean. They will
reflect heat better, and you will save energy.
43. Match the size of the pan to the heating element.
More heat will get to the pan, and less will be lost to
the surrounding air.
44. Get in the habit of turning off the elements or surface
units on your electric stove several minutes before
completing the allotted cooking time. The heating element will stay hot long enough to finish the cooking
without wasting electricity.
45. Turn off the oven five to 10 minutes before cooking
time is up and let trapped heat finish the cooking.
46. When using the oven, cook as many foods as you can
at one time.
47. Avoid opening the oven door repeatedly to check food
that is cooking. This allows heat to escape and results in
the use of more energy to complete the cooking of
your food. Instead, watch the clock or use a timer.
48. Use small electric cooking appliances or ovens for
small meals rather than the kitchen range or oven.
They use less energy.
49. Use pressure cookers and microwave ovens if you have
them. They save energy by reducing cooking times.
50. Don’t preheat the oven unless absolutely necessary,
and then for no more than 10 minutes.
51. Avoid using the broiler. It is a big energy user.
52. Thaw frozen foods before cooking. It will save time
and energy.
53. When buying a dishwasher, look for an energy-efficient model with air power and/or overnight dry settings. These features automatically turn off the dishwasher after the rinse cycle. This can save you up to 10
percent of your dishwashing energy costs.
54. Scrape dishes and rinse with cold water from the
faucet before loading them into the dishwasher. Avoid
using the dishwasher's pre-rinse cycle.
55. Be sure your dishwasher is full but not overloaded
when you turn it on.
56. Don’t use the “rinse-hold” on your machine for just a
few soiled dishes. It uses three to seven gallons of hot
water each time you use it.
57. Don’t keep your refrigerator or freezer too cold.
Recommended temperatures: 38 degrees F. to 40
degrees F. for fresh food compartments of the refrigerator; 5 degrees F. for the freezer compartment.
Separate freezers for long-term storage should be
kept at zero degrees F. Open the refrigerator or freezer door only when necessary, and don’t hold it open
any longer than necessary.
58. Regularly defrost manual-defrost refrigerators and
freezers. Frost buildup increases the amount of energy
needed to keep the refrigerator at its proper temperature. Never allow frost to build up more than onequarter of an inch.
59. If possible, don’t place your refrigerator or freezer in
direct sunlight or near the stove.
60. Make sure your refrigerator door seals are airtight. Test
them by closing the door on a piece of paper or dollar
bill so it is half in and half out of the refrigerator. If
you can pull the paper or dollar out easily, the hinge
may need adjusting or the seal may need replacing.
61. Wash clothes in warm or cold water, rinse in cold.
62. Fill washers and clothes dryers but do not overload
63. Keep your clothes dryer’s lint screen clean and its outside exhaust free of obstructions. Clean the lint screen
after each load of laundry, and check the exhaust regularly. A lint screen in need of cleaning and a clogged
exhaust can lengthen drying time and increase the
amount of energy used.
64. Save energy by using the old-fashioned clothesline.
Doing so can make clothes seem fresher and dryer
than those emerging from a dryer.
65. Remove from the dryer and hang clothes that will
need ironing while they are still damp.
66. Save energy needed for ironing by hanging clothes in
the bathroom while you’re bathing or showering. By
doing so, you can steam some wrinkles out and cut
down on ironing time.
67. Avoid piecemeal ironing. If possible, iron a large load
of clothes at a time.
Bathroom Energy Savers
68. Take showers rather than tub baths, but limit both
your showering time and the water flow if you want
to save energy.
69. Install a water-flow controller in the pipe at the showerhead. This saves a considerable amount of hot water
and the energy used to produce it.
70. Install an aerator in the bathroom sink.
71. Don’t let water run while shaving. This wastes hot
water and the energy used to heat it.
72. Repair leaky faucets immediately.
Indoor Lighting
73. Use compact fluorescent bulbs. They produce about
three to four times as much light per watt as incandescent bulbs. While compact fluorescents are initially
more expensive, they last up to 10 times longer.
Compact fluorescent bulbs work best in the kitchen,
bathroom or a work area. Deluxe white fluorescent
bulbs produce the most pleasing light.
74. Halogen bulbs are another energy-efficient choice for
indoor and outdoor lighting. They use about 25 percent less energy than traditional incandescents, and
produce an intense white light, making them ideal for
spot, flood and security lighting. Halogen torchieres,
however, can pose a fire hazard due to the high temperatures produced by these bulbs.
75. Turn off lights in any room not being used, even if
your absence will only be momentary.
76. When using incandescent bulbs, use the lowest wattage
possible or convenient. In many cases, a lower wattage
bulb can be substituted for the one currently being used.
77. Light-zone your home and save electricity. Concentrate
lighting in reading and work areas, and where it’s
needed for safety, such as in stairwells. Reduce lighting
in other areas, but avoid very sharp contrasts.
78. Consider installing solid-state dimmers. They make it
easy to reduce lighting intensity in a room, saving energy. Most will not work with fluorescent bulbs however.
79. Use one large bulb instead of several small ones in
areas where bright light is needed.
80. Socket extenders and special adapters let you use
compact fluorescent bulbs in your table lamps.
81. When choosing a new lamp, buy three-way lamps.
They make it easy to keep lighting levels low when
intense light is not necessary, and that saves electricity.
Use the high switch only for reading or other activities
that require brighter light.
82. “Long life” bulbs emit less light than a standard incandescent bulb of the same wattage. Use them only
where the long-life feature may be advantageous,
such as hard to-reach places.
Outdoor Lighting
83. Turn on outdoor lights only when needed.
84. Use timers, motion detectors, heat sensors or photocell
controls for light fixtures when possible.
