Manufacturers in the US have racked up an estimated $2.4 billion (£1.6bn) in energy savings in the last five years.
They spend more than $200 billion (£131bn) every year to power their plants, according to the US Department of Energy.
Under its ‘Better Plants Programme’, manufacturers and water and wastewater treatment companies set a goal to boost energy efficiency and reduce energy intensity by 25% over a 10-year period across all their US operations.
Around 160 industrial organisations representing more than 2,400 facilities have joined the programme.
They consume around 11.4% of the US manufacturing sector’s total energy use – equivalent to the state of Tennessee’s annual energy consumption.
Energy Secretary Ernest Moniz said: “When companies save energy, they also save money and reduce harmful carbon pollution. This is especially true in the manufacturing sector where energy costs are often a significant contributor to total operating costs.
“Manufacturers participating in the Better Plants programme, including our new partners in the water and wastewater treatment sector, are leading the way in showing how energy efficiency is a smart business strategy as well as a smart conservation strategy that will help to protect our environment for future generations.”
