There Are Many Ways You Depend On Electricity

As your electric supplier, we’ve developed this brochure to help you determine your electric usage. We hope this will help you use your electricity as efficiently as possible.

This graph shows how energy is used in an average home with four family members. Your use may vary depending on your lifestyle, the size of your family and the size, age and efficiency of your appliances. The amount used also varies with the weather and the amount of insulation in your home’s walls and ceiling.
Appliances that are manufactured today are typically much more efficient. As appliances age, their efficiency decreases. Knowing the age and life expectancy of your electric appliances can help you understand your electrical use.

Average Life Expectancy In Years

Clothes Washer8-10
Clothes Dryer14
Electric Range12
Electric Water Heater10-12
Heat Pump16


If your appliances are at or nearing the end of their expected life, you may plan ahead. When replacing old appliances pay particular attention to energy efficiency. In most cases, the energy-efficient choice will save you money.

Operating cost per hour can be estimated if you know:

  1. Wattage of the appliance
  2. Cost of electricity (cost per KWh)


To estimate the number of kWh (units of electricity used in one hour) first determine:

  1. The wattage of the appliance from its nameplate
  2. Apply the following formula:


Wattage x 1 (hour) = kWh   (units of electricity used per hour)

To figure operating cost per hour: kWh (units used) x Cost/KWh=Cost/hour

To determine average cost per kWh from your electric bill:


(bill) $69.38    =  $.0925 per KWh
(KWh) 750

  Cost per KWh 9.25¢

Electricity used per hour

1500 x 1(hour) = 1.5 Kwh

 Cost per hour of operation:
1.5 KWh x 9.25¢ per KWh = 13.88 (cents per hour)
