Renewable Energy

Harnessing Solar Power

We're using the power of the sun and installing solar panels to lower our energy costs. Efforts like these are not only good for the environment, but they also keep prices low for customers.

Generating power naturally

Walmart has more than 180 renewable energy projects in operation or development around the world, generating enough energy to power 78,000 American homes annually. Here are a few ways we’re working to become powered by 100% renewable energy.

Producing our own renewable energy

Walmart is a leader in testing and scaling renewable energy projects in our stores, including solar, micro-wind on our parking lots, biodiesel generators and fuel cells. These locally generated power sources have the potential to meet up to 60% of a store’s energy needs. Examples include:

  • 150 solar installations in seven countries, delivering 71 million kilowatt hours of energy annually to our stores, clubs and distribution centers – enough to take 9,600 vehicles off the road for a year. In California alone, 75% of our facilities will use some form of renewable energy by the end of 2012.
  • 26 fuel cell installations in the U.S., delivering 65 million kilowatt hours of electricity annually.
  • We are testing onsite micro-wind, large-scale wind, solar water heating, as well as solar thermal in various markets, including Canada, Chile, China, Mexico and the U.S. 

Purchasing green energy to power our stores

We’ve changed the way we buy power by going directly to the source. Through long-term power purchase agreements (PPA), we’re supporting renewable energy developers and, ultimately, driving down the cost of clean energy for everyone. We have five off-site utility wind projects, including:

  • 348 stores in Mexico supplied by wind power via Eléctrica del Valle de Mexico. This provides 17% of Walmart Mexico’s energy needs and has reduced carbon emissions by an estimated 137,240 tons annually.
  • 350 stores in Texas receive up to 15% of their electricity needs from Duke Energy’s wind farm in Notrees, Texas.
  • 14 stores in Northern Ireland are supplied by wind power.

Improving the grid

We’re committed to working with stakeholders to make the grid as renewable as possible, as fast as possible. In three markets, for example, we’ve participated in green power purchase programs, resulting in more than 500 million hours of renewable energy annually.
