You know the statistics… according to the U.S. Department of Energy (DOE), electric motors consume more 50 percent of all electrical energy in the United States and more than 85 percent of industrial production electrical energy. Electric motors account for roughly $85 out of every $100 of a manufacturing/process plant's electrical bill.

An article written by John O’Brien titled “How Much Do Electric Motors Really Cost,” and published in the June 2009 issue of Pumps and Systems Magazine breaks down the true cost of an electric motor.  One 200 hp pump motor running 6 days a week for 50 weeks a year, writes O’Brien, will cost more than $70,000 dollars at the end of one year. Interestingly enough, most end-users spend more time negotiating the initial purchase price of a motor than understanding the true cost for operating that motor. According to the DOE, the average life of an electric motor is 20 years. During the life of an electric motor the initial purchase price represents just 1 percent of the total cost of owning and operating it. The largest cost of operating an electric motor is the power cost. DOE estimates the power cost to be more than 90 percent during the electric motor's 20-year life
