Why is My Electric Bill Higher Than My
Neighbor’s?
Family Size
There is a direct relationship between the number of people
living in a home and the amount of energy that is used.
That’s especially true if you have teenagers at home. In
addition, if friends and relatives are visiting, you can expect
to use more energy for cooking, baking, laundry and hot
water.
You just answered this question yourself. It’s your electric
bill, and it reflects the amount of electricity consumed by
you and your family in your home or on your farm.
Your neighbor may have a completely different set
of circumstances…different number living at home,
different lifestyle, different size home with a different style
of construction, etc. Your bill may also differ from your
neighbor’s bill due to the varying numbers and types of major
appliances as well as different heating and cooling systems.
Heating and Cooling
Heating and air conditioning uses the largest chunk of your
home’s energy dollar. Conversely, energy conservation
designed to reduce heating or cooling load will have the
greatest impact on your monthly energy bills. Heating and
cooling expense is driven by seasonal weather extremes.
An average home will experience its highest energy bills of
the year during the hottest months of the summer and the
coldest months of the winter. To reduce your heating and
cooling expense follow these simple tips!
To assure that your heating and cooling system is
operating efficiently, have it serviced annually by a
certified technician.
Inside and outside coils should be kept clean and free of
debris.
Return filters should be changed monthly.
Set thermostat at 78 degrees in the summer and 68
degrees in the winter. For each degree higher or lower
you set the thermostat, you save an additional 2% to 3%
on heating or cooling costs.
Install and utilize a programmable thermostat and save
an additional 10%.
Have a HVAC technician check carefully for duct leaks.
Leaks that are found should be sealed with fiberglass
mesh and mastic sealant.
When purchasing a new system, make sure that it is
sized correctly for your home and has the highest
efficiency rating (SEER) that your budget can afford.
Lifestyle Makes a Difference
You have complete control over how you use your
electricity by choosing the conveniences that are necessary
for you to maintain your standard of living.
The way you live and the way you use your electrical
appliances may have a greater impact on your consumption
of electricity than the number of appliances you use. Let’s
examine some of the driving factors that can make your
electric bill seem higher than average.
Home Energy Costs
Get a clear picture of which parts of your home use the
most energy.
The first step in reducing home energy costs is to review
last year’s utility bills. Using the national percentage
averages below, a homeowner who spent $2,500 a year for
home energy would have paid roughly:
$1,400 for heating and cooling
$575 for appliances and lighting
$400 for water heating
$125 for refrigeration
Contact your local Touchstone Energy7 cooperative
representative to review your bills and receive a more
accurate estimate.
Water Heating
Hot water plays an important role in everyone’s life, but
many people require substantial quantities of hot water,
and that results in higher energy use. Ask yourself some of
the following questions…
When I take a bath, do I use hot water sparingly, or is
the tub completely full?
Do I take short showers, or do I stay in the shower
until the hot water gets cold?
Do I repair leaky faucets, or simply let them drip and
waste hot water?
Do I operate washers and dishwashers with a full
load, or just whenever convenient?
Are my hot water pipes insulated?
Try this & save…
Install water flow restrictors and
aerators in sink faucets. This can save
you money by reducing water use.
Reduce the water heater temperature
to 120ºF. This can decrease heat loss
from your tank. Dishwashing may
require higher temperature settings
F. However, many
around 130ºF.
dishwashers now have a
temperature boost
that allows you
to keep the
water heater
temperature
set lower.
It is important to note that hot water usage is the second
largest energy consumer in the household behind heating
and cooling.

Did you know…?
Try this & save…
Tankless water heaters are ideal for applications
where space is at a premium or in small vacation
homes, and can serve quite effectively in point of use
applications. However, their use as the central source
of hot water in a residence should be carefully
considered.
While tankless water heaters offer some modest
energy savings over storage water heaters (possibly
as little as $36/year for electric water heaters), these
minimal gains are at the expense of substantially
higher initial purchase costs, higher installation costs
(upgraded power requirements), higher maintenance
costs, and possible lifestyle changes to accommodate
the limited flow rate output of tankless water heaters.
For example: taking a shower while washing clothes
could require as much as 6 gallons per minute of hot
water. It’s unlikely that any electric tankless water
heater could supply the heating capacity to meet this
demand.
One way you can eliminate
phantom loads is by plugging
them into a plug strip that is
equipped with its own power
switch. Simply switch the power
strip on and off as you use the
appliance. For appliances that
have remote controls, this method
will disable the unit’s remote
control until you turn the power
strip on.
Appliance Use
The wise use of appliances can have a positive effect on
your energy consumption.
Ask yourself these questions:
Do I turn off lights and ceiling fans when a room is
not in use, or do I leave them on?
Does the television set entertain the entire family, or
does it entertain an empty room?
Do I leave my computer and peripherals on for
extended periods of time when not in use?
These are prime considerations that affect the amount of
electricity you use to maintain your lifestyle.
Phantom Loads
We have a host of time and labor-saving appliances
available to help us do our work whenever we need their
service. Some of these appliances use electricity only when
you turn them on.
But consider this…many appliances are quietly using
energy around the clock, even though you think they are turned
off! The power supplies to your instant-on TVs, computers
and their peripherals, cordless phones, cell phone chargers,
clocks on microwaves and electric ranges, etc., are examples of
“phantom loads” that steadily consume electricity whether you
are using the device or not.
In addition, any appliance that has a cube-shaped
transformer (sometimes called AC adaptors) on the end of
its cord is also creating a phantom load. That’s why these
transformers feel warm even though the device is off.
Another type of phantom load is the oil heater in an airsource heat pump. Even though heat pumps are an energy
efficient means for heating and cooling your home, there
is a steady, subtle draw of electricity to heat the oil fluid
in the sump of the heat pump. Phantom loads add up to a
huge waste of electricity in the U.S. that costs consumers
billions of dollars per year and many billions of kilowatthours. The total phantom load in your home could account
for substantial energy use.
Make a Plan
Vacation Use
When vacation time comes and you’re planning to be gone
for a couple of weeks, your electric bill should decrease
significantly, right? Wrong!
Many people believe that when they leave for vacation,
their electric meter stops until they return. Ask yourself a few
questions before assuming your electric bill should decrease by
any considerable amount during vacation.
First, was your heating or cooling system turned off or
the thermostat set up or down in your absence? If these
preparations are not made before you leave, your heating and
cooling system will work to maintain your thermostat’s preset
temperature even if no one is at home.
Second, was the water heater turned down or off while you
were gone? If the electric water heater is left energized during
vacation, it will continue to operate and maintain the tank
temperature even if you’re not using any hot water. Were the
refrigerator and freezers emptied and turned off? If not, they
will continue to operate to maintain the preset temperatures.
Perhaps you can make arrangements with a neighbor
to keep an eye on your place and adjust the heat and/or air
conditioner and water heater shortly before you return. In
addition, you may wish to unplug all appliances not in use. If a
light is to be left on, it should be connected to a timer.
Also, many vacationers bring home several days or weeks
of laundry. This will give your electric water heater and washer
and dryer a workout your first day or two back home.
Did you know…?
The new big screen TVs
and plasma TVs are
great for watching your
favorite movies or sports
network. But they can use
as much as 850 kilowatthours per year.

Check
Seal exterior cracks and holes like
the ones found around plumbing and
electrical penetrations to the outside
and ensure tight-fitting windows.
Small cracks or holes in the building
exterior (walls, windows, doors,
ceiling and floors) can really
add up to substantial
heating or cooling
losses. Install
weather stripping
and caulking to
stop air leaks.
Other Sources of High Usage
Sometimes you’ll find equipment using electricity that you
thought was turned off. It could be a faulty motor control on
an air conditioner, well pump or pool pump, a leaky hot water
faucet, or lights and equipment simply left on. By comparing
your use with that in the Appliance Energy Use Guide on
pages 6 and 7, you may determine whether that equipment
is using an unusually high amount of electricity.
However, if you can’t find the problem, contact your
electrician or seek proper advice from your electric cooperative.
Act
Seasonal Use
Keep Records
In addition to vacations, take a look at some of the seasonal
uses for electricity that may cause an increase in consumption.
These include crop dryers, air conditioners, portable heaters in
the garage or basement, engine heaters that keep your vehicles
ready to run, holiday lighting, heat tape to keep pipes from
freezing…. the list goes on and on.
Also, don’t forget about hobbies or businesses that operate
out of the home.
Keep records for a few months each season. Learn how
changes in your activities can affect your energy budget.
Use Less Energy
Make changes to how you use your energy. Make easy
changes first. Here are some ideas to get you started.
Set thermostats for energy economy. Make changes
in temperature levels gradually so you and your
family can adjust. It is estimated that 1ºF temperature
change can reduce heating and cooling costs by 2-3%.
By installing a programmable thermostat, changes
such as these require minimal effort.
Keep heating and cooling systems working more
efficiently by replacing filters monthly and having
your system serviced annually.
Turn off lights whenever possible.
Use energy efficient lighting such as T-8 fluorescent
lighting, compact fluorescent lighting and high pressure
sodium lighting to cut lighting costs by up to 75%.
Lower the temperature setting on your water heater
to 120ºF.
Fix hot water faucet leaks.
Reduce phantom loads.
Record
You can do something about how you and your family
use energy. A big, first step is tracking current energy
consumption.
Meter Reading Dates
A factor that enters into higher than normal electric bills is the
number of days between meter readings. Check the number of
days in your billing cycle and the average number of kilowatthours used per day to make accurate comparisons. Many people
often overlook this important consideration.
It’s important to read your meter on the same day of each
month. If you notice that your usage has increased substantially
from one month to the next for no apparent reason, you will be
able to diagnose equipment failure sooner.
Other Things to Consider
Is the Meter Accurate?
The electric meter is often accused of inaccuracy, but it’s
seldom the culprit. Your meter does not lie. When it records
more electricity being used, try to find out why by looking at
your family’s activities during that period…was the weather
warmer or colder than normal? Was it a washday? See what
activities, if any, can be altered to use energy more wisely.
The meter is a finely calibrated, highly accurate device
used to measure power use. Your electric cooperative has
a continuing program to test the accuracy of all its meters
to assure that you are being billed for the exact number of
kilowatt-hours used. All meters are tested on a regular basis.
Historical data bears out the fact that in more than 99% of
the cases, the electric meter is accurate. High bills are almost
always traced to other causes.
Swimming Pool–The filter pump runs continuously in
most cases during the summer months. The horsepower
rating on the motor usually ranges from .5-1.5 and can use
360 to over 1,000 kilowatt-hours per month. Utilize a timer
to reduce the pumps operational time.
Ceiling Fans–Ceiling fans and portable fans can help
make you feel cooler, but they don’t cool the room. Use
them wisely; when you are not in the room, turn them off.
Conversely, most ceiling fans have a reversing switch. This
can be very effective in moving warm air from the ceiling
in the winter and redistributing it throughout the room.

Did you know…?
Location–If you do replace an older major appliance
that is still working, please think twice before putting that
older unit somewhere else like in the garage or basement.
Freezers and refrigerators are designed to be placed in
70ºF-conditioned areas. Putting them outside in a garage
that gets uncomfortably hot in the summer time just causes
the refrigerator or freezer to run more often. In addition,
these places aren’t always the cleanest, so the coils collect
dust, pet hair, etc., quicker than in the house, which affects
their efficiency.
Air Leaks–It’s been estimated that a typical home with
all of its foundation and wall cracks, holes around sink
plumbing and electrical outlets, gas and fireplace flues, and
use of recessed can lighting in ceilings have air leakage
that it is equivalent to leaving a door open year-round.
Take the time to seal all of these openings with caulk or
foam and apply insulated foam gaskets behind outside wall
switches and receptacles. Add sufficient insulation where
needed in attics and walls.
UsingEnergy-EfficientHeatingandCooling
Systems–If you have heating and cooling units that are
more than 15 years old, consider replacing them with
energy-efficient units. Great strides have been made in
improving the energy efficiency of heating and cooling
equipment. If you use evaporative cooling systems (swamp
coolers), follow the manufacturer’s recommendations
regarding maintenance items such as pads, water changes,
etc. Do not operate them simultaneously with refrigerated
air conditioning systems and remember to close windows
and doors when switching to refrigerated-type systems.
Also cover the evaporative coolers when not in use to
eliminate air leaks through them. Talk with your electric
cooperative about what is available.
Shut the door–Every time the entry doors are opened
during heating and cooling seasons, unconditioned air from
the outside enters the home, which has to be heated or
cooled. Try to reduce these door openings to a minimum.
Water pumps are occasionally the cause of
unexpected high energy use. Common failures
that cause a pump to gobble energy include water
leaks, defective pressure tanks and defective
pressure switches. Water leaks and defective
pressure tanks can cause your pump to start and
stop more often than necessary. Defective pressure
switches may cause the pump to run continually. If
water for pumping continues to be available to a
pump experiencing these problems, it can run for
a long time before failing. When pumps are in the
well (submersible) or located away from the home,
the owner may be unaware there is a problem.
Check your pump’s run time. A water pump should
run for a short time (normally less than 30 seconds)
to reach its pre-selected pressure, shut off, and
not run again until enough water is used to reduce
pressure.
Weather–Many of the appliances/equipment we use
in our lifestyles are directly tied to the weather. As the
seasons change – causing the temperature to turn cooler or
warmer–it usually has a direct effect on our air conditioning
and heating use.
HotTubs–Although there is nothing more soothing
than sinking into a hot tub after a long day, these energy
wasters are nothing more than a huge water heater with an
open face. Many times, owners don’t even take the time
to cover them up when not in use. Hot tubs can use $25 to
$50 of energy per month or more.
Closing Off Vents–Perhaps you have unused rooms
where you shut off the vent damper thinking you will
save electricity by not heating or cooling that room. What
you have really done is created an “unbalanced pressure”
situation which will result in less efficient operation due
to short cycling of the furnace or heat pump and blower.
In the case of a gas furnace, this situation could introduce
carbon monoxide into the home through back drafts.
Rather than closing off vents, consider adjusting the
thermostat temperature up in summer and down in winter.
SpaceHeaters–Most space heaters are 1500-watt units
that are used to “warm up” a room such as a bathroom or
used temporarily while you work in an unheated garage. A
typical space heater used just two hours per day can account
for 90 kilowatt-hours of electricity in a month’s time.
Replacing Major Appliances
Age–Sometimes it is hard to justify replacing a major
appliance for efficiency reasons until the unit dies. When
replacing major appliances, look for the Energy Star label
(www.eere.energy.gov).
Try this & save…
To reduce your lighting costs
use compact fluorescents
wherever possible as they
are the most efficient lighting
on the market. They use 70%
less energy, produce only
about 10% of the heat, and
last 10 times longer than
incandescent bulbs. Install
motion sensor light switches.
They automatically shut off
lights when not in use.

How to Estimate Energy Use & Cost
The wattage of appliances (equipment) and the amount of operating time can vary greatly. The following
information will show how to determine where the energy dollars are going in your home.
STEP 1
Look on your utility bill and find the cost per kWh that is charged in your area. If you cannot locate a bill, rate
information can be found by logging onto your cooperative’s Web site or by giving them a call.
STEP 2
EXAMPLE OF SERIAL PLATE
Since the wattage of an appliance (equipment) determines the electrical
usage per hour, the second step is to determine the wattage.
The wattage of an appliance is found on the serial plate. But it is
possible that the electrical requirements will be expressed in volts and
amperes, rather than watts. If so, multiply volts times amperes to obtain
the wattage; e.g. 120 volts x 12.1 amperes = 1,452 watts.

STEP 3
Use the formula shown below to estimate usage and cost.
Watts (Divided By) 1000 = KW
KW x Rate $ per KWh = Operational Cost per Hour
To determine monthly cost
Operational Cost per Hour X # hours operated per day X # days in the month = $
To determine yearly cost:
Operational Cost per Hour X # hours operated per day X 365 days in a year = $
