A kilowatt-hour is the electrical energy consumed in one hour at the constant rate of one kilowatt. The average household in the United States uses about 8,900 kilowatt-hours of electricity each year.. Power is defined as the rate at which work is done or energy is consumed.
On average, a home in the US uses 911 kWh of electricity per month. By taking this number and multiplying it by the cost per kWh of a given month, we can estimate the cost of residential electricity for any state. As an example, each home in Mississippi was mailed an electric bill of $100.21 (11 cents x 911 kWh) on average for March 2017.
