The Glendora Sam's Club is part of Walmart's commitment to accelerate and broaden its sustainability efforts through solar power.

The Walmart in Caguas, Puerto Rico is one of five Walmart facilities on the island equipped with solar panels. In addtion to Caguas, Walmart added solar to sites in Manati, Baymon and two in Ponce.

Walmart is installing solar power generating systems in several locations in California and Arizona. The majority of these sites will utilize thin film panels as seen on this Mountain View, Calif. store.  

One of Walmart’s broad sustainability goals is to be powered by 100% renewable energy, including the use of solar panels on the Covina, Calif. Walmart.

Walmart’s white roofs help reduce energy use and have a lower heat island effect than a darker roofing color. The skylights are part of the company’s daylight harvesting system, which can save an average of 800,000 kwh of energy annually.

Wind Energy at Palmdale, California Sam's Club

Adjacent to the Milton, Ontario Walmart store, the 20-killowatt wind turbine is expected to generate as much as 50,000 kilowatt hours of electricity per year, enough to power four average size Canadian households. The wind turbine has been designed for low wind speed areas, where wind power has not been previously practical, and can operate in wind speeds as low as 10 kilometres per hour.

Walmart Puerto Rico has added LED parking lot lights to 22 of its stores. The technology is expected to reduce energy by 48% and maintenance costs by more than 70%.
