How Much Electricity Do You Use?
What is a Kilowatt Hour (kWh)? The term kilowatt hour is simply
an easy way to say 1,000 watts of power used for one hour. One
kilowatt hour is a 100-watt light bulb on for ten hours.
KEEPING TRACK OF YOUR ENERGY USAGE
Keep track of your electricity conservation efforts by reading your electric
meter. It’s easy, and by comparing daily or weekly readings you can identify
habits that result in saving electricity and money.
Electric meters have a digital display and show the total, or cumulative,
energy consumption in kWh. They operate much like the odometer on a car.
You compare beginning and ending readings to find out your energy use
over a given period of time (one day, one week, one month).
Another way to keep track is to borrow a Kill A Watt meter,
either from Emerald PUD or from your local library. This
monitor (picture at left) measures the actual electrical
consumption of various electrical devices and appliances. It
can display projected costs by hour, day, week, month, or year.
The knowledge you gain from the Kill A Watt can save you
money and help you conserve electricity.
HOME ENERGY USE CHART
The chart on the reverse side shows the typical monthly residential electrical usage and costs for
various appliances and equipment found in your home. Use the chart to figure the kilowatt hours and
monthly cost for each appliance you use. Add them up to get a total for the month. The operating costs
shown are calculated using a weighted average rate of Emerald PUD’s current Tier 1 residential rate of
6.96¢ per kWh and Tier 2 residential rate of 7.96¢ per kWh.
This chart can help you understand how your electrical usage adds
up. You can see which appliances use the most energy. Typically,
home heating is the largest user of energy in your home. Water
heating is the second largest user.
Remember, these are only estimates. Many factors such as your
family size, lifestyle, weather, the size of your home, and how well
your home is weatherized, can affect usage.
Appliance Use Cost Calculator
April 2017
Costs shown below are based on the average usage for residential
customers (1,300 kWh per month) and calculated using both the
Tier 1 residential rate of $0.0696/kWh and Tier 2 residential rate of
$0.0796/kWh and national average appliance usage.

COST EQUATION
Divide the watts of an
appliance by 1000 to
get kilowatts (kW), the
electricity your appliance
uses. Multiply kW by hours
used per day, then by 30
days, then by the weighted
average residential rate of
$.075/kWh, to arrive at the
monthly cost.
