Unilever plc (NYSE:UL) and NRG Energy (NYSE:NRG) announced today that they are joining forces to help Unilever's U.S. business go greener than ever before.

While Unilever's U.S. subsidiary already purchases third-party renewable energy credits to cover 100% of its electricity use, this latest NRG Energy partnership will put power production in Unilever's own hands. NRG Energy says it will work with Unilever to identify various on- and off-site alternative energy sources to provide Unilever with "100% clean energy" at its U.S. sites.

"Unilever, through its commitment to clean energy, is demonstrating in a truly meaningful way that it cares about its consumers and their well-being in a manner far beyond that of conventional companies seeking to sell products. They also are demonstrating through actions, rather than just words, what being a leader in the clean energy economy means," said David Crane, president and CEO of NRG Energy, in today's press release.

Kees Kruythoff, president of Unilever North America, echoed similar aspirations. "This transformational partnership with NRG to move all of our U.S. operations to 100 percent renewable energy will make our business more resilient, sustainable, and profitable. It is our hope and expectation that our collaboration with NRG will also inspire a broader acceleration and uptake of renewable energy technologies."

Unilever has 400 brands spanning 14 categories of home, personal care, and food products.

The two corporations expect to reach their goal by 2020 and said they will share updates..
