New Energy-Efficiency Standards for Electric Motors, Coolers, Freezers
The Energy Department on May 9 announced two new energy-efficiency standards for electric motors and walk-in coolers and freezers. These standards combined will help reduce harmful carbon pollution by up to 158 million metric tons—equivalent to the annual electricity use of more than 21 million homes—and save businesses $26 billion on utility bills through 2030.
Electric motors are used extensively in a variety of applications, such as industrial machines, conveyor belts, and escalators. Last year, approximately 5 million electric motors were shipped in the United States. A standard 30-horsepower electric motor consumes approximately 62,000 kilowatt-hours per year. The new standard will save consumers nearly $16 billion and prevent the emissions of 96 million metric tons of carbon dioxide through 2030.
In addition, the Energy Department issued a final efficiency standard for walk-in coolers and freezers, such as the milk display at the supermarket. This standard will help cut energy bills by about $10 billion and reduce carbon dioxide emissions by 62 million metric tons through 2030. The efficiency standards established today will update the 2010 standards for electric motors and the 2009 standards for walk-in coolers and freezers. These standards incorporate feedback from industry, consumer, and environmental advocacy groups, and other stakeholders and will go into effect three years after publication in the Federal Register for walk-in coolers and freezers and two years after publication in the Federal Register for electric motors.
