What does it cost?
Using energy wisely pays off in lower
energy bills. But, how much lower?
This guide will help you estimate the
typical monthly costs of operating
various electrical appliances and
equipment around the home. We’ve
also included some “best tips” that’ll
save the most energy.
Figuring your costs
The charts on the following pages provide
you a handy guide to help you calculate
how your home uses electricity and what
it can cost. All you have to do is:
1. Estimate the number of hours
you typically use each appliance
per month.
2. Multiply the number of hours
of use by the hourly cost listed
for each appliance to estimate
the cost per month.
How is electricity priced?
Electricity is priced per
kilowatt-hour used.
The more kilowatt-hours
used, the higher the bill.
A kilowatt is shorthand
for 1,000 watts – “Kilo”
(Greek for 1,000) and
watt. Appliances and
lights are rated by how
many watts they use.
A kilowatt-hour is 1,000
watts used for one hour.
For example, one kilowatt-hour
will run a 100 watt light bulb
for 10 hours.
So, how do you figure what a
specific electric appliance or
equipment will cost to run?
It’s easy.
Here’s the formula based on a
month’s time:
wattage
X hours used per month X cost per kilowatt hour
1,000

Cost estimates are based on $0.10 per kWh. The “Typical Monthly Cost” per month column
should be used for comparative purposes only. Actual use varies from home to home
depending on the number of people in the household, weather and numerous other
factors. Additionally, appliances are available in a wide range of power consumptions.
The sizes and usage calculations are intended only to represent a typical size, and costs
and usage will vary. This information should be used as a general guide.
Savings Tips
• Insulation works. It’s the best way to save
on heating and cooling costs.
• Caulk and weather-strip around windows
and doors, and where plumbing and
electrical conduit enters your home.
• Replace furnace, heat pump and air
conditioner filters regularly.
• Use programmable thermostats to
regulate use of heating systems.
• Make sure fireplace and woodstove
dampers are closed when not in use.

Savings Tips
• Set your water heater thermostat at
120 degrees.
• Clean lint filters after
each load of clothes.
• Fix water faucet leaks. Sixty drops per minute
will waste nearly 200 gallons per month.
• Use the water-saver washing option and energy
saver drying option on your dishwasher.
• Wrap your water heater if it’s old and located
in an unheated space.
• Replace older appliances with energy
efficient models.
• Use warm or cold water instead of hot
for laundry.
• Use low-flow faucet aerators and showerheads.

Saving Tips
• Check to make sure refrigerator and
freezer gaskets seal tightly.
• Use pots and pans
with flat bottoms.
• Use a convection oven, microwave or
smaller electric appliances whenever
possible.
• Next to space heating
and water heating, your
refrigerator could be the
biggest electricity user in
your home. Keep the
refrigerator door shut as
much as possible.
• Defrost freezer compartments before
frost exceeds 1/4 inch.
• Never use the oven to heat your home.

Saving Tips
• Turn off lights when not needed.
• Consider replacing as many incandescent
bulbs with energy saving compact
fluorescent bulbs as possible. Compact
fluorescent bulbs use 75 percent less
electricity as conventional bulbs and
last up to 10 times longer.*
• Light colored interior paints on
walls/ceilings help reduce amount of
lighting required.
• Automatic timers and motion detectors
are a useful way to manage lighting.

Cost estimates are based on $0.10 per kWh. The “Typical Monthly Cost” per month column
should be used for comparative purposes only. Actual use varies from home to home
depending on the number of people in the household, weather and numerous other
