In a growing trend among retailers looking to cut costs, organic supermarket chain Whole Foods and retail giant Wal-Mart announced plans this week to add solar panels to a number of their stores.Whole Foods officials said the panels will generate about 30 percent of the power needed to run the stores. Wal-Mart has been toying around with alternative energies since it unveiled its solar-powered store in Dallas, Texas. The retailer will now expand the program to include up to 20 stores in California.
