The U.S. Department of Energy recognized 11 companies that have met energy-efficiency goals through the Better Buildings, Better Plants Program. The Energy Department says that manufacturers nationwide spend more than $200 billion a year to power their plants. Through the Better Plants Program, manufacturers commit to improve their energy intensity by 25% over 10 years, or an equally ambitious level for their sector.

The Department says that over the last four years, Better Plants Partners have improved the energy intensity of their operations (a measure of a facility’s energy use per unit of output) by about 2.4% a year, exceeding projected business-as-usual rates for U.S. manufacturers as a whole. The 11 companies that recently met their goal to improve energy intensity include BPM Inc., Celanese International Corp., Holcim (US) Inc., Legrand North America, Lennox International Inc., Patriot Foundry & Castings, Procter & Gamble, Texas Instruments, ThyssenKrupp Elevator, Toyota and Verso Paper Corp.

The Department says that more than 140 companies currently participate in the Better Plants Program, representing more than 2,300 manufacturing facilities and close to 11% of the total U.S. manufacturing energy footprint. Cumulatively, these companies have saved around 320 trillion British Thermal Units of energy, equal to saving nearly $1.7 billion in energy costs.
