Machine Drives Neutralizing Industrial Output with Increased Energy Efficiency

EIA Calculates Electric Motors Efficiency by Industry

Daily Fusion, October 21, 2013

Machine drives, which are primarily electric motors, pumps, and fans, account for about half of the manufacturing sector’s delivered electricity use and 8% of the sector’s total fuel consumption. Their wide use across many industries results in a substantial impact of electric motors efficiency on the demand placed on power grids.

EIA’s Annual Energy Outlook 2013 (AEO2013) projects that the continuing increase in the energy efficiency of machine drives offsets an increase in industrial output, resulting in relatively flat levels of electricity consumption by machine drives.
