DOE’s analyses estimate lifetime savings for electric motors purchased over the 30-year period that begins in the year of compliance with new and amended standards (2016-45) to be 7.0 quadrillion British thermal units (Btu). The annualized energy savings—0.23 quadrillion Btu—is equivalent to 1% of total U.S. industrial primary electricity consumption in 2013.
>” Nearly half of the electricity consumed in the manufacturing sector is used for powering motors, such as for fans, pumps, conveyors, and compressors. About two thirds of this machine-drive consumption occurs in the bulk chemicals, food, petroleum and coal products, primary metals, and paper industries. For more than three decades the efficiency of new motors has been regulated by federal law. Beginning in mid-2016, an updated standard established this year by the U.S. Department of Energy (DOE) for electric motors will once again increase the minimum efficiency of new motors.
The updated electric motor standards apply the standards currently in place to a wider…
