Sixteen major employers in the US and two stakeholder groups have joined the Department of Energy’s initiative to expand workplace charging options in the country.

The Workplace Charging Challenge is a collaborative effort to increase the number of US employers offering workplace charging by tenfold in the next five years.

Energy Secretary Steven Chu remarked that the market for energy-efficient and electric vehicles is expanding considerably and allows for cost savings as well as reduction of carbon emissions.

The employers who have joined the initiative include AVL, Bentley Systems, Biogen Idec, Bloomberg LP, The Coca-Cola Company, the City of Sacramento, Dell, Facebook, The Hartford, The Hertz Corporation, National Grid, New York Power Authority, NRG Energy, OSRAM SYLVANIA, Raytheon Company and Southern California Edison.

"These American companies are taking strong steps to make their operations smarter and more fuel-efficient — setting an example for others to follow and helping America lead the global race for a growing industry," added Chu.

The California Center for Sustainable Energy and the Green Parking Council also inked the Ambassador Pledge to support and promote the workplace charging initiative.
