HELPFUL WAYS
TO SAVE MONEY
AND ENERGY
SAVING ENERGY AND
MONEY IN YOUR HOME
The major energy users in your home —
heating system, air conditioning, water
heater, refrigerator, dryer, lighting — all
contribute to your overall utility bill.
This brochure offers tips to help you use
them more efficiently, lower your energy
use and save money on your monthly
energy bill.
SEALING AIR LEAKS
I

Insulate your attic floor or top floor ceiling to a
minimum of R-49. R-values indicate the
resistance of an insulation material to heat flow.
The higher the R number, the more effective the
insulating capacity. R-values appear on the
packages of insulation materials.
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.
Insulate heating and cooling ducts in unheated
or uncooled areas.
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.
Test windows and doors for air tightness. Add
weather stripping and caulk where necessary.
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.

WATER HEATING
I
I
I
I
I
I
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.
Purchase the correct size heater. Consider your
family’s hot water needs. If your water heater is
too large, it uses more energy than needed. If it
is too small, you may run out of hot water.
Install your water heater near the kitchen. The
kitchen is where you use the hottest water.
When the water heater is located near the
kitchen, hot water doesn’t have to travel as far
and less heat is lost.
Install a heat loop or in-line trap. If you add a
new water heater to your home, consider
having a heat loop or in-line trap installed.
These mechanisms can be inexpensive to install
and keep hot water from moving into the
piping system when you are not using hot
water. Ask your plumbing contractor for details.
Turn down the water heater temperature dial to
120 degrees F, or to the “warm” setting if you
have a dishwasher. Be sure to check your
manufacturer’s instructions for minimum water
temperature.
Insulate the outside of your electric water heater
with an insulation blanket to reduce heat loss. Also
insulate water pipes with half-inch foam or pipe
tape for insulation wherever pipes are exposed. On
cold water pipes, insulate four to five feet nearest
to the water heater.

Keep your heating equipment well tuned with
periodic maintenance by a professional service
representative.
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.
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.
Clean or replace the filter in your forced-air
heating and cooling systems each month. Foam
filters can be rinsed with water but be sure they
are dry before replacing. Fiberglass filters need
to be replaced periodically.
Keep draperies and shades open during the day to
let the sunshine in; close them at night.
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.
Weatherize your home by weather stripping or
caulking around doors and windows. This will
help keep heat from your system inside the
home.

Adjust the thermostat in small degree changes –
your home won’t heat or cool faster by cranking
it up.
Consider installing a programmable thermostat.
Programmable thermostats can save up to 10%
of heating and cooling costs annually.
When leaving the house for the day, turn down
your heat setting a few degrees. This will save
energy while you are away.
YOUR COOLING SYSTEM
I
I
I
I
I
Be sure the air conditioner is fully charged with
freon so it operates efficiently and keep your
cooling system well tuned with periodic
maintenance by a professional service
representative.
When selecting a central air conditioning unit, be
sure to choose one with the proper capacity and
highest efficiency, don’t oversize it.
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.
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.
Remember to cover and insulate it during the
winter to prevent heat loss.
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.

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.
Keep lamps or television sets away from the
thermostat. Heat from these appliances is
sensed by the thermostat and could cause your
system to run longer than necessary.
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.
Use duct tape to seal the cracks between each
section of an air duct on your central air
conditioning or forced heating system.
Keep lights low or off when not needed. Electric
lights generate heat and add to the load on
your air conditioner.
Plant shade trees strategically around your
home. Properly selected and planted shade trees
can save up to $80 annually on the average
electric bill.
Use window or whole house ventilating fans to
cool your home.
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.
When leaving the house for the day, turn up
your air setting a few degrees. This will save
energy while you are away.

BATHROOM ENERGY SAVERS
I
I
I
I
Take showers rather than baths, but limit both
your showering time and the water flow to save
energy.
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.
Use low flow showerheads in all showers and
faucet aerator in the bathroom sink.
Don’t let water run while shaving or brushing
your teeth. This wastes hot water and the
energy used to heat it.
LAUNDRY

Place the washer close to the water heater also.
Water loses heat as it flows through pipes.
When the washer is located near the water
heater, hot water doesn’t have to travel as far to
reach the washer, and less heat is lost. Insulating
the pipes between the water heater and washer
helps retain heat.
Wash clothes in warm or cold water. Rinse in
cold water.
Fill washers and clothes dryers but do not
overload them.
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.
Save energy by using a clothesline. Doing so can
make clothes seem fresher and dryer than those
emerging from a dryer.
Place a dry towel in the dryer with each load of
wet clothes to absorb dampness and reduce
drying time.
7
I
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. If
possible, iron a large load of clothes at a time.
KITCHEN ENERGY SAVERS
I
I
I
I
I
I
I
I
I
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.
Install an aerator in your kitchen sink faucet.
Boil water in a kettle or covered pan as the
water will come to a boil faster and use less
energy.
Keep range-top burners and reflectors clean.
They will reflect heat better and you will save
energy.
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.
Turn off the oven five to 10 minutes before
cooking time is up and let trapped heat finish
the cooking and 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.
Don’t preheat the oven unless absolutely
necessary and then for no more than 10 minutes.
Use pressure cookers and microwave ovens if
you have them. They save energy by reducing
cookIng times.
Avoid using the broiler. It is a big energy user.

Clean or replace air filters. Replace filters on
exhaust hoods, humidifiers, vacuums, etc.
Clogged filters impair performance and cause
the units to run longer and use more energy.
DISHWASHING
I
I
I
When buying a dishwasher, look for an energyefficient model with air power and/or overnight
dry setting. These features automatically turn off
the dishwasher after the rinse cycle. This can
save you up to 10 percent of your dishwashing
energy costs.
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.
Clean the filter. If your dishwasher has a filter
screen, clean it regularly. A clean appliance runs
more efficiently.
REFRIGERATOR/FREEZER
I
I
I
Set the refrigerator thermostat at 38 degrees F
for fresh food compartments and 5 degrees F
for freezer compartment. A small thermometer
placed in the refrigerator or freezer will help you
set it correctly. 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.
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 one quarter of an inch.
Vacuum refrigerator coils at least every three
months. The dirt buildup makes the refrigerator
use more energy to keep contents cool.
9
I
I
I
If possible, don’t place your refrigerator or
freezer in direct sunlight or near the stove. Heat
will cause the unit to use more energy to stay
cold.
Make sure your refrigerator door seals 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.
If you keep a second refrigerator in your garage
or basement, keep empty space filled with
gallon water jugs. The extra storage helps to
maintain the temperature inside.
HOME OFFICE AND ELECTRONICS TIPS
I
I
I
I
I
Select energy-efficient office equipment and
turn off machines when they are not in use to
result in significant energy savings.
Use an ENERGY STAR-labeled computer which
can save 30%-65% more energy than
computers without this designation, depending
on usage.
Spend large portions of time in low-power
mode to not only save energy but to help
equipment run cooler and last longer.
Put your laptop AC adapter on a power strip
that can be turned off (or will turn off
automatically) to maximize savings; the
transformer in the AC adapter draws power
continuously, even when the laptop is not
plugged into the adapter.
Use the power management settings on
computers and monitors for significant savings.
It is a common misperception that screen savers
reduce a monitor’s energy use. Use automatic
switching to sleep mode or simply turn it off.

Consider buying a laptop for your next
computer upgrade; laptops use much less
energy than desktop computers.
Use Smart Power Strips to save energy and be
able to shut down multiple items quickly.
Reduce vampire loads by using a Smart Power
Strip. Vampire loads are all of those chargers
that are plugged in but not charging anything at
the moment. Chargers use energy when not
being used, so unplug them until needed, put
computers to sleep and learn how to activate
the power management features on your
computer.
Purchase a good selection of high-quality
rechargeable batteries and a charging unit.
You’ll save money in the long run and keep
hazardous materials out of our environment.
Use rechargeable batteries for products like
cordless phones and digital cameras. Studies
have shown they are more cost effective than
disposable batteries.
Unplug battery chargers when the batteries are
fully charged or the chargers are not in use.
LIGHTING
I
I
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.
Halogen bulbs are another energy efficient
choice for indoor and outdoor lighting. They use
about 25 percent less energy than traditional
incandescent bulbs 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.

Purchase holiday light strings that feature LEDs
or light-emitting diodes. LED lights use 90
percent less energy than standard incandescent
bulbs.
Turn off lights in any room not being used, even
if your absence will only be momentary.
When changing bulbs, use the lowest wattage
possible or convenient. In many cases a lower
wattage bulb can be substituted for the one
currently being used.
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.
Consider installing solid-state dimmers. They
make it easy to save energy by reducing the
lighting intensity in a room.
Use one large bulb instead of several small ones
in areas where bright light is needed.
Turn on outdoor lights only when needed and
install lights with motion detectors so they come
on only when needed.
Use timers, motion detectors, heat sensors or
photocell controls for light fixtures when
possible.
Removing one light bulb from your garage door
opener is a creative energy saving tip.
