Your Unique
Energy Needs
As the cost of energy goes up, more and more people are
concerned about their rising utility bills. Consumers are
looking for ways to control their energy use and reduce
their impact on the environment. The best way to do this
is to first be aware of how much energy you use each
month and how it is being used in your home. This involves
learning how to read your meter, keeping track of energy
use and using your meter as a tool to locate problems.
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.
In this way, you can budget your energy use just like you
budget for groceries and other household items.
Space Heating & Cooling
Take a few moments now to work through this guide. Then,
if you still have questions about electrical use and costs,
call the professionals at your local electric cooperative.
We’re here to help!
Lifestyle Makes a Difference
You have complete control over how you use your electricity by
choosing the ingredients that are necessary for you to maintain
your standard of living.
The way you live and the way you use your electrical appliances
have a greater impact on your consumption of electricity than the
number of appliances you have.
For example, about nine percent of the energy used in the average
American home is for water heating. Hot water plays a very
important role in everyone’s lifestyle, but many lifestyles require
substantial quantities of hot water, which results in high energy use.
Let’s look at some of these “lifestyle considerations” that can
make your electric bill seem higher than “normal.”
From a comfort standpoint, most of us prefer to be relatively cool in
summer and warm in winter. Others prefer temperature extremes.
Humidity plays an important part in our year-round comfort, too.
If you operate dehumidifiers in summer (and, to a lesser degree,
humidifiers in winter), this contributes to household energy
consumption because they tend to run often. Portable space
heaters, air conditioners and fans in such places as the garage and
basement also contribute to our energy consumption.
By taking a look at your “comfort” lifestyle in terms of maintaining
relative humidity and temperature, you can use energy wisely in
many ways. These range from adding insulation, weather-stripping
and caulking, to turning down the heat and turning off the air
conditioning in unused rooms.
Water Heating
Hot water plays a very important role in everyone’s lifestyle, but
many people require substantial quantities of hot water and that
results in higher energy use.
Ask yourself some of the following questions:
Family Size
• When I take a bath, do I use hot water sparingly, or is the tub
completely full?
There is a direct relationship between the number of people
living in a home and the amount of energy that is used. That’s
• 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
when convenient?
Try this & save. . .
Install water flow restrictors and aerators in sink faucets.
This can save you money by reducing water use. Reduce the
hot water temperature to 120°F. This can decrease heat loss
from your tank. Dishwashers may require higher temperature
settings. Many now have a temperature boost that allows you
to keep the water heater temperature set lower.

sector and energy management consciousness is likely to start at home.
Why is my electric bill higher than
my neighbor’s?
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.
Your neighbor may have a completely different set of
circumstances—different number of people living in the home,
different lifestyle, different size home, different equipment and
methods, etc. These and many other factors, make a comparison
with your neighbor less meaningful.

The effects of a home energy management program can pay big

People in the Upper Midwest have relatively good lifestyles and we
tend to use more energy than the national average. This applies
to all forms of energy, not just electricity. The pie chart shows how
electricity is used in U.S. homes.

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 will decrease by any
considerable amount during vacation.
First, did you turn the water heater down or off while you were
away? 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.
Did you empty the refrigerator and freezers and turn them off? If not,
they will continue to operate to maintain the preset temperatures.
Take a look at other electrical appliances that keep running while
you are on vacation—clocks, fans and power ventilators, heating
and air conditioning equipment, lights, computers, chargers,
docking stations and TVs use some energy for their “instant-on”
features. Most of these can be unplugged during vacation time to
save energy while they are not needed.
Vacations & Seasonal Use
When vacation time comes and you plan to be gone for a couple of
weeks, your electric bill should decrease significantly, right? Wrong!
Try this & save. . .
Lower the thermostat during cool months and turn it up for air
conditioning, especially when the building is not occupied.
You can use a programmable thermostat to automatically adjust
temperatures to accommodate weekly schedules.

Make Arrangements
Perhaps you can make arrangements with a neighbor to keep an
eye on your place and adjust the heat, water and/or air conditioner
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. If you intend
to be gone for an extended period of time, contact your electric
cooperative and make arrangements so your electric service will
remain uninterrupted.
Read your meter upon leaving and again when you return. This
will let you determine the number of kilowatt hours used
while you were gone.
Many vacationers bring home several days or weeks of
dirty laundry when they return. This will give your electric
appliances a workout your first day or two back home.
Remember These
In addition to vacation, take a look at some of the
seasonal uses for electricity that may cause an increase
in consumption. This includes air conditioners, portable
heaters in the garage or basement, engine heaters to
keep your vehicles ready to run, heat tape to keep pipes
from freezing…the list goes on and on.
Let’s not overlook hobbies or businesses that operate
from home.
They also have an effect
on the number of kilowatt

Meter Tracking
These days most electric meters
are recorded through an automated
system. You still have the ability
to track your energy use at the
meter to your home, or online if
this is available at your co-op. If
you notice a substantial increase
from one month to the next for no
apparent reason, you will be able
to diagnose an equipment problem
sooner.
Fluctuation in the number of days
between meter readings may
create a higher than typical electric bill. People often overlook
this important consideration. Check the number of days in your
billing cycle to make accurate comparisons.
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 colder or
warmer than normal? 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 electric 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 percent of the cases,
the electric meter is accurate. Higher bills are nearly always
traced to other causes.
Check
Common Sources of Trouble
Common sources of trouble include electrical faults in wiring
systems that are usually due to physical damage, moisture, dirt or
improper connections.
Sometimes you’ll find equipment using electricity that you thought
was turned off. It could be a thermostat, well pump, baseboard
electric heat or basement and attic lights.
• Adjust air
conditioning
a few degrees
warmer in the
evenings.
• During the winter
months, lower
the thermostat
setting when you
retire at night.
If no problems are found, your electric cooperative
has test meters available to record the electrical
consumption of items plugged into them. By
comparing your recorded use with that of our
list for home appliances and equipment, you can
determine whether your own equipment is using
an unusually high amount of electricity.
• Select higher
efficiency lighting
options like compact
fluorescents (CFLs)
or LEDs. Place them
in areas where you
use lighting most
often.
However, if all methods fail, contact your
electrician or seek further advice from your electric cooperative.
• Keep heating and cooling systems working more efficiently by
replacing filters and cleaning coils.
Act
• Remove unneeded light bulbs in areas where lighting is too
bright.
Do Something About Your Electric Bill
You can do something about your electric bill by acting on the
information presented in this brochure.
Take a few moments each day (at the same time) to jot down the
reading on your electric meter.
Monitor your daily meter readings for one month to get a better
idea of your energy use patterns. Note the activities that increase
your energy use.
Keep Records
Keep records for a few months each season. Learn how changes in
your activities can affect your energy budget.
• Turn out lights whenever possible. Reduce or eliminate
unnecessary lighting.
• Keep fixtures clean.
• Use less hot water. Lowering the temperature setting on the
water heater can offer savings.
• Fix hot water faucet leaks.
• Insulate pipes.
When your electric bill indicates more electricity use than normal,
try to find out why by looking at your family’s activities during
that billing period. For instance, was there above average air
conditioning or
heating used?
Use Less
Change your habits. Start with easy changes.
• Set thermostats for energy economy. Make changes in
temperature levels gradually so you and your family can adjust.

How to Estimate Energy Use and Cost
The wattage of appliances (equipment) and the amount of operating time can vary greatly. The following
information will show you how to determine where the energy dollars are going in your home.
STEP 1
$ amount of electric bill = Average kWh Cost
kWh used
Since the cost of electricity is determined by the
number of kilowatt hours (kWh) used during a billing
period, the first step is to determine your average cost
per kilowatt hour.
EXAMPLE
$154
1400 kWh
= $0.11 per kWh
Check with your local electric cooperative for current rate.
STEP 2
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 by amperes to obtain wattage; e.g. 120
volts x 12.1 amperes = 1,452 watts.
Example of Serial Plate
MICROWAVE OVEN
AMPS
12.1
HERTZ
60
FORM NO. 000000
CODE
0
VOLTS 120
WATTS 1452
MODEL NO. 00000
SERIAL NO. 0000
STEP 3
Use the formulas shown in the following examples to estimate usage and cost.
A light uses 100 watts and is left on 15 hours. How many kWhs are used and what does it cost?
100 watts x 15 hours x
1 kW
= 1.5 kWh used
1,000 watts
Your cost = 1.5 kWh X $0.11/kWh = $0.165 or 16 1/2 cents
A microwave oven uses 1,450 watts and is used for 30 minutes. How many kWhs are used and what does it cost?
1,450 watts x 0.5 hours x
1 kW
= 0.725 kWh or 0.73kWh used
1,000 watts
Your cost = 0.73 kWh X $0.11 = $0.083 or 8 cents
STEP 4
To find your daily cost for electricity, divide your bill by the number of days in your billing period.
EXAMPLE
$154
30 days
= $5.13 which is your daily cost
To find the daily cost for electricity per person in your family, divide the daily cost by the number in your family.
EXAMPLE
8
$5.13
4
= $1.28 per person per day
