Energy
Guide
Every time you flip a switch, push a button, turn a knob or
set a thermostat, you are making a decision to buy electricity.
Most of these are cost-effective decisions that give you good value.
However, unlike other buying decisions, you usually don’t know the
cost of what you are about to buy with electricity.

Electric Appliance Energy Guide
Energy Requirements
and Operating Costs
This profile has been prepared to help customers compare the energy usage of various
home appliances. Total usage and cost will vary from home to home, depending on factors
such as appliance age, family size and lifestyle.
To represent the varying summer and winter rates and fuel costs an average cost of
15.9 cents per kilowatt-hour was used in these calculations.

Kilowatt Hours and Operating Costs
Appliance energy capacity is rated in watts. Your electric bill is based on the number of watts of electricity you use and the number of hours you use them. Electric usage is measured in kilowatt-hours
(kWh.) To convert to kilowatts divide Watts by 1,000 . One kilowatt used for one hour is one kilowatt-hour.
You can approximate the electrical cost for any electrical appliance in your home as follows:
Appliance
Wattage
Hrs. used
X in one month
X
Cost per kWh
=
Approx.
Monthly Cost
1000
The calculations in this brochure are based upon an average cost of 15.9 cents per Kilowatt hour.
The Excess Fuel Cost Surcharge, which reflects costs incurred by LIPA in purchasing fuel used to generate
electricity and for electric power purchased from other generators, is part of your total electric bill. This
surcharge helps LIPA recover costs not included in the base electric rates. For additional information on
about the Excess Fuel Cost Surcharge, please visit www.lipower.org or call 1-800-490-0025.
Home Lighting
Home lighting is one of the variables in household energy consumption that must be evaluated on
an individual basis. The best way to inventory lighting energy is to survey your home room by room,
adding up the wattage of your lightbulbs and estimating the hours each is on during the month.
If, in your living room or family room there are two lamps, each with a 100 watt bulb, and these
lamps are usually on five hours a day, then this room would use:
Example:
200
5 Hours
30
X
X
Watts
Per Day
Days
1000
or 30 kWh per month for lighting this room.If you were to replace the 100 watt incandescent bulbs with 29
watt efficient fluorescent bulbs you could reduce your usage to 8.7 kWh/month.
