Walmart seems to be taking its renewable energy initiative seriously with the recent announcement that it will install solar panels on up to 60 stores throughout California. Once the projects are complete, over 75% of Walmart stores in the California will sport a solar system and, combined, generate up to 70 million kWh of renewable energy every year.

“California presents a great opportunity for Walmart to make significant progress toward our sustainability goals by installing solar power on more than 130 store rooftops throughout the state,” said Kim Saylors-Laster, Walmart vice president of energy.  “Walmart has reduced energy expenses by more than a million dollars through our solar program, allowing us to pass these savings on to our customers in the form of everyday low prices.”

SolarCity will own, install and maintain the solar power systems, which are anticipated to provide 20 to 30% of each store’s total electric needs. The worldwide superstore aims to eventually be powered 100% by renewable energy.

“Our solar efforts in California have proven to be a great way for Walmart to build our renewable energy program,” said Mack Wyckoff, senior manager of renewable energy at Walmart.  “We are confident that we will continue to grow our solar energy program in the U.S. and around the world because of the initial success we have had in California.”
