Energy efficiency in manufacturing plants recognized by EPA

Feb. 29, 2016

Collectively, 70 manufacturing plants across the country cut energy bills by a total of $476 million last year.

Collectively, 70 manufacturing plants across the country cut energy bills by a total of $476 million last year. They also reduced greenhouse gas emissions by more than 5 million metric tons, which is the equivalent of the average annual energy use of more than 450,500 households. Last week the U.S. Environmental Protection Agency (EPA) announced the names of these plants, which received its Energy Star certification for energy efficiency.

"Energy Star certified manufacturing plants are driving the kinds of efficiencies and innovations that keep our country strong," said EPA Administrator Gina McCarthy. "They’re proving every day that businesses can save on energy, cut down on bills, and reduce harmful greenhouse gas emissions all at the same time."

Energy Star certifies plants that reach the top 25 percent of energy performance for their industries nationwide according to independent verification. Since the certification began in 2006, 148 plants have saved over 618 trillion British thermal units (TBtu) in energy, which is the equivalent of preventing more than 41 million metric tons of carbon dioxide equivalent emissions and saving enough energy to provide the total yearly energy needs of approximately 3.5 million American households.

The most recent recipients include plants from the the automotive, cement manufacturing, corn refining, food processing, glass manufacturing, pharmaceutical manufacturing, and petroleum refining industries. Nine plants earned certification for the first time.
