When you’re shopping for new appliances, always look for the
ENERGY STAR label. Homes with ENERGY STAR® appliances can
save more than $300 a year in operating costs, about 25%
of average annual costs. Working together we can make a
difference.

How much do your appliances cost to operate?
The cost to operate these products varies widely but averages
about $20 per month. To save energy:
Some appliances cost little to operate. Some cost a lot. The graph
on the next page gives typical monthly costs. It helps to determine
which appliances deserve energy-saving efforts.
• Use a cover
• Buy a large heater to heat the water quickly
• Turn on the heater before use
• Turn off the heater when weather permits
Use this brochure to make energy decisions. Compare operating
costs of a microwave and the oven or a whole house fan and
central air conditioner. Make informed appliance choices.
Considerations:
• Location - indoors or out?

The energy prices in this brochure are not a prediction of future
costs/ rates. This range of gas and electric rates is provided to
cover possible fluctuations in energy prices mainly due to volatility
of natural gas costs. Natural gas is traded on a national commodity
exchange and its costs are affected by supply and demand.

Estimated monthly costs for big energy users
Big energy users cost the most to operate. Use these appliances
wisely to lower monthly bills.
Find the average amount of electricity used each month in the
kWh/month column. It’s based on average-size appliances and
average monthly use.
3
Many big energy users are controlled by a thermostat. They turn
on and off automatically. Energy use is estimated with an average
amount of “on” time.

Big energy users
Cost per hour for medium to small energy users
The cost per hour of operation is given for appliances that use
med­ium to small amounts of energy.
Find the column that is closest to the electric or gas rate you pay.
Use this column to find the hourly cost of operation. Multiply the
cost per hour by the number of hours per month the appliance is
used. This is the monthly cost.
Figuring operating costs
Have an appliance that’s not listed? Calculate the operating cost
or borrow a portable energy meter from the library.
Gas appliances
Divide the Btu rating by 100,000. This is the number of therms
used in one hour of operation. Multiply by the rate per therm
(see page 3, Get your utility rate) and by the number of hours
the appliance is used.
Cost of operation =
Btus
100,000
x rate/therm x hours used
For example: A gas clothes dryer uses 20,000 Btus per hour.
Estimate that it runs one hour per load. How much does it cost
to dry one load?

*Typical well pump for single-family residence runs about one to two

Find the wattage of the appliance. It may be stamped on the back or
bottom. Divide the wattage by 1,000 to get the kilowatts used per
hour. Multiply this by the rate per kilowatt-hour (see page 3, Get
your utility rate) and by the number of hours the appliance is used.
Cost of operation = Wattage x rate/kWh x hours used
1,000
Some appliances cycle on and off automatically, using energy only
when they are on. To figure their energy use, estimate the amount
of time they use energy.
For example: The dehumidifier uses 620 watts. Estimate that it runs
10 hours a day. How much does it cost to run the dehumidifier
per day?
620
Cost of operation =
x $.14 x 10 = $0.87
1,000
Some appliances list only amperage and volts. They may be
stamped on the back or bottom. If it plugs into a standard outlet,
it’s a 120 volt appliance. Use amperage multiplied by volts to figure
the operating cost.
Cost of operation = Amperage x volts x rate/kWh x hours used
1,000
Caution: Using this formula usually overestimates operating costs.
Portable Energy Meter
For the most accurate electric appliance operating cost, borrow
a portable energy meter. Accurate and easy to use, this tool has
helped hundreds of individuals save energy and make appliance
decisions. It may be reserved for checkout through all public
libraries in the South Central Library System.

Find the wattage of the appliance. It may be stamped on the back or
bottom. Divide the wattage by 1,000 to get the kilowatts used per
hour. Multiply this by the rate per kilowatt-hour (see page 3, Get
your utility rate) and by the number of hours the appliance is used.
Cost of operation = Wattage x rate/kWh x hours used
1,000
Some appliances cycle on and off automatically, using energy only
when they are on. To figure their energy use, estimate the amount
of time they use energy.
For example: The dehumidifier uses 620 watts. Estimate that it runs
10 hours a day. How much does it cost to run the dehumidifier
per day?
620
Cost of operation =
x $.14 x 10 = $0.87
1,000
Some appliances list only amperage and volts. They may be
stamped on the back or bottom. If it plugs into a standard outlet,
it’s a 120 volt appliance. Use amperage multiplied by volts to figure
the operating cost.
Cost of operation = Amperage x volts x rate/kWh x hours used
1,000
Caution: Using this formula usually overestimates operating costs.
Portable Energy Meter
For the most accurate electric appliance operating cost, borrow
a portable energy meter. Accurate and easy to use, this tool has
helped hundreds of individuals save energy and make appliance
decisions. It may be reserved for checkout through all public
libraries in the South Central Library System.

Many big energy users are controlled by a thermostat. They turn
on and off automatically. Energy use is estimated with an average
amount of “on” time.

Cost per hour for medium to small energy users
The cost per hour of operation is given for appliances that use
med­ium to small amounts of energy.
Find the column that is closest to the electric or gas rate you pay.
Use this column to find the hourly cost of operation. Multiply the
cost per hour by the number of hours per month the appliance is
used. This is the monthly cost.
Figuring operating costs
Have an appliance that’s not listed? Calculate the operating cost
or borrow a portable energy meter from the library.
Gas appliances
Divide the Btu rating by 100,000. This is the number of therms
used in one hour of operation. Multiply by the rate per therm
(see page 3, Get your utility rate) and by the number of hours
the appliance is used.
Cost of operation =
Btus
100,000
x rate/therm x hours used
For example: A gas clothes dryer uses 20,000 Btus per hour.
Estimate that it runs one hour per load. How much does it cost
to dry one load?
Cost of operation = 20,000
