100 Manufacturing Plants Earned ENERGY STAR Certification In 2018

Automotive, baking, cement, corn refining, food processing, glass manufacturing, pharmaceutical manufacturing, and petroleum refining plants qualified, 15 of them for the first time.

Superior energy performance earned 100 manufacturing plants ENERGY STAR certification in 2018, according to the U.S. Environmental Protection Agency (EPA). Together, these plants reduced their energy bills by more than $400 million, saved more than 70 trillion British thermal units (TBtu) of energy, and achieved broad emissions reductions, including 4.5 million metric tons of greenhouse gas emissions. The energy savings are enough to meet the annual energy needs of nearly 440,000 American households.

Since 2006, the ENERGY STAR Industrial Program has annually certified manufacturing plants for performing within the top 25 percent of energy performance in their industries nationwide. More than 200 plants have achieved this distinction since 2006.

EPA’s ENERGY STAR industrial program provides industry-specific energy benchmarking tools and other resources for 19 different types of manufacturing plants, enabling plants to compare energy performance to others in the same industry and establish meaningful energy performance benchmarks and goals. Only plants in the top 25 percent of energy performance nationwide can earn the ENERGY STAR. Plants from the automotive, baking, cement, corn refining, food processing, glass manufacturing, pharmaceutical manufacturing, and petroleum refining sectors are among those that qualified in 2018.
