Walmart Makes Major Commitment to Renewable Wind Power

Power purchase equivalent to annual usage of more than 20,000 average American homes

BENTONVILLE, Ark., Nov. 20, 2008 – Today Wal-Mart Stores, Inc. (NYSE:WMT), announced its first substantial purchase of wind energy in the U.S. The wind power will supply up to 15 percent of the retailer’s total energy load in approximately 360 Texas stores and other facilities.

The renewable energy will come from a Duke Energy wind farm under construction in Notrees, Texas, and is expected to begin producing electricity for Walmart by April of 2009.

“We’re purchasing renewable power at traditional energy rates,” said Kim Saylors-Laster, vice president of energy for Walmart. “The wind power purchase will result in a significant decrease of greenhouse gas emissions and aligns perfectly with Walmart’s long-term goal of being supplied by 100 percent renewable energy.”

The project will provide roughly 226 million kilowatt-hours (kWh) of renewable power each year or the energy equivalent of washing 108 million loads of laundry -- enough for every household in Austin, Texas to do laundry for a year. By purchasing this amount of clean, renewable energy, Walmart will avoid producing more than 139,000 metric tons of carbon dioxide (CO2) emissions per year. This is equal to taking approximately 25,000 cars off the road or eliminating the CO2 produced by 18,000 homes annually.

“Walmart's action shows that low-carbon technology is increasingly competitive and long-term sustainability is a winning business strategy,” said Andrew Aulisi, director of the markets & enterprise program at the World Resources Institute. “Walmart's smart and innovative approach should be used more widely.”

The wind purchase is another example of Walmart’s ongoing commitment to become a more sustainable company and serves as a complement to its solar project announced last year. In May 2007, Walmart announced it would equip up to 22 locations in Hawaii and California with solar panels. Walmart estimates the solar power systems are helping reduce greenhouse gas emissions by 6,500-10,000 metric tons per year.

By integrating wind power into its electricity load, Walmart is building on its diversified energy portfolio and creating more opportunities for advancements in clean energy through research and innovations. This power purchase in the deregulated market territory in Texas is expected to support the creation of green jobs at the West Texas facility. Walmart will use the results of its wind power purchase to explore additional ways to achieve its goal of being supplied by 100 percent renewable energy.
