WASHINGTON – Wal-Mart has signed a contract to help power hundreds of its stores using wind energy, one of the largest investments in the field by a U.S. retailer.
The four-year agreement with Duke Energy is expected to provide up to 226 million kilowatt-hours of power each year to about 360 stores and distribution centers in Texas, about 15 percent of the total electricity used. The company said the purchase will result in the reduction of about 139,000 metric tons of carbon dioxide, the equivalent of what 25,000 cars would emit.
The move is the latest step in the company’s three-year-old effort to transform itself into a more sustainable business. Wal-Mart chief executive Lee Scott has vowed that the retailer will eventually be completely supplied by renewable energy. The deal with Duke is expected to be announced Thursday.
“That’s just a huge, huge goal for us to work toward,” said Kim Saylors-Laster, vice president of energy for Wal-Mart. “We’re actually very pleased with our results and excited about the things that we’re learning.”
Nearly two years ago, Wal-Mart began talks with wind power company Tierra Energy, which was based in Austin, Texas, to supply its stores. When Tierra was bought by North Carolina-based Duke last year, the company brought Wal-Mart with them.
“They have a very compelling case for their sustainability and environmental effort,” said David Marks, senior vice president for wind energy at Duke. “They were very focused on trying to make as much of their Texas electricity load be renewable as they can.”
