Use this guide to create an awareness of your lifestyle and learn what effects it can
have on your energy budget and the environment. Make this your first step to better
energy management.
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.
In this way, you can budget your energy use just like
you budget for groceries and other household items.
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 energy cooperative. We’re here to help!
Lifestyle Makes a Difference
Space Heating & Cooling
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.
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 we operate
dehumidifiers in summer (and, to a lesser degree,
humidifiers in winter), this contributes to our household
energy consumption because they tend to run
continuously. Portable space heaters, air conditioners, and
fans in such places as the garage and basement also
contribute to our energy consumption.
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 38 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.”
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.
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.
2
By taking a look at our “comfort” lifestyles in terms of
maintaining relative humidity and temperature, we 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:
•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 when convenient?

Appliance Use
We have a host of time and labor-saving devices at our
service to aid us in our work whenever we need them. As
you progress through this guide, you may notice how
many more electrical servants you have than you expected.
These appliances work for you around the clock, whenever
you choose to use them. The wise use of appliances can
have a positive effect on your energy consumption.
Ask yourself these questions:
•Do I turn off lights when a room is not in use, or do
I leave them on?
•Does the television entertain the entire family or does
it entertain an empty room?
•Do I use the oven to reheat one dish, or do I use the
microwave?
These are prime considerations that affect the amount
of electricity you use to maintain your lifestyle. All
Americans are part of the residential sector, and energy
management consciousness is likely to start at home.
The effects of a home energy management program can
pay big dividends!
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 the amount of energy used in the
residential sector in the Midwest.

Make a Plan
Vacations & Seasonal 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 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.
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.
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.

Try this & save…
Seal exterior cracks and
holes and ensure tightfitting windows. Small
cracks or holes in the
building exterior (like 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.
Seal off unused areas. Don’t heat or cool these
rooms. Storage areas are a good place to start.
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,
and TVs use some energy for their “instant-on” feature.
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 energy 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.
Also, many vacationers bring home several days or
weeks of dirty laundry. This will give your electric water
heater a workout your first day or two back home.
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 kilowatthours you use.

Record
You can do something about how
you and your family spend energy. A
big, first step is tracking current
energy consumption. Take a few
minutes each day and jot down the
reading on your electric meter. Your
analysis will be more accurate if you take
your readings at the same time each day.
Subtract the previous day’s reading from the
current reading to determine how many
kilowatt-hours were used. Contact your energy
cooperative for a portable meter to measure the
consumption of individual appliances.
You may wish to call an electrician to check wiring
and appliances for grounds, shorts, and other
malfunctions.
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 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 use has increased
substantially from one month to the next for no
apparent reason, you will be able to diagnose an
equipment problem sooner.
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 energy 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. High
bills are almost always traced to other causes.
Check
• Use lower wattage
bulbs and buy
higher efficiency
compact
fluorescents. Place
them in areas where
they are used most
often.
Common Sources of Trouble
Common sources of trouble include
electrical faults in wiring systems that are
usually due to physical damage, moisture
and 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.
• Keep heating and
cooling systems
working more
efficiently by replacing
filters and cleaning
coils.
If no problems are found, your energy
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 that
equipment is using an unusually high amount
of electricity.
•Keep fixtures clean.
However, if all methods fail, contact your electrician or
seek further advice from your energy cooperative.
• Consider using high pressure sodium lightbulbs for
outdoor lighting.
Act
• Use less hot water. Lowering the temperature setting on
the water heater can offer savings.
Do Something About Your Electric Bill
• Fix hot water faucet leaks.
You can do something about your electric bill by acting
on the information presented in this brochure.
• Insulate pipes.
Take a few minutes each day (at the same time) to jot
down the reading on your electric meter.
When your meter records 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 heater or air conditioner use?
Record 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.
•Remove unneeded light
bulbs in areas where
lighting is too bright.
•Turn out lights whenever possible. Reduce or
eliminate unnecessary lighting.
Keep Records
Keep records for a few months each season. Learn how
changes in your activities can affect your energy budget.
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.
• Adjust air conditioning a few degrees warmer in the
evenings.
• During the winter months, lower the thermostat
setting when you retire at night.
Try this & save…
Reduce lighting expenses. Turn off
lights when not in use.
Compact fluorescent lighting is the
most efficient lighting on the market.
These bulbs use 70 percent less energy
and last up to 10 times longer than
incandescent bulbs. Different wattage
sizes are available to fit your lighting needs.

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
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
kWh used
$144.20
1400 kWh
STEP 2
= Average kWh Cost
= $0.103 per kWh
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.
AMPS
HERTZ
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.

MODEL NO. 00000
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
1,000 watts
= 1.5 kWh used
Your cost = 1.5 kWh X $0.103/kWh = $0.1545 or 151/2 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
1,000 watts
= 0.725 kWh or 0.73kWh used
Your cost = 0.73 kWh X $0.103/kWh = $0.075 or 71/2 cents
STEP 4
To find your daily cost for electricity, divide your bill by the number of days in your billing period.
EXAMPLE
$144.40
30 days
= $4.81 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
$4.81
4
= $1.20 per person per day
