What is a kWh?
Your electricity usage is measured in kWh. A kWh, or kilowatt-hour, is equivalent a power consumption of 1,000 watts for 1 hour.
How do I know how much my appliance, space heater, etc. will add to my electric bill?
Every electrical device requires a certain amount of power (measured in watts) to operate, and power over a period of time is energy (measured in kWh). Here’s how to calculate energy:
Watts (W) ÷ 1,000 = Kilowatts (kW)
Kilowatts (kW) x Hours of Use = Kilowatt Hours (kWh)
The Department of Energy also has an online calculator that can be used to calculate energy consumption and energy cost of appliances.
An example is an electric space heater, as many of the common models are 1,500 Watt (W) units. Just one 1,500 W space heater running continuously for 30 days can contribute approximately 1,080 kWh, or approximately $115-$120 to an electric bill!
1500 W space heater = 1.5 kWh
1.5 kWh x 24 hours a day = 36 KWh
36 kWh per day x 30 days of use = 1,080 kWh used over 30 days!
What uses the most energy in my home?
If you have electric heating, your electric heating system and water heater are typically the two single largest consumers of electricity in your home. Together, they typically make up approximately 50% of your total energy consumption.
