Wal-Mart Unveils High-Efficiency Supercenter
Not one to ever stay out of the news for one reason or another, Wal-Mart this week unveiled what it calls its most energy-efficient U.S. store yet: the HE.5 prototype.
The store, located in Las Vegas, is said to use up to 45 percent less energy than your basic Supercenter. It’s also designed specifically for the Southwest’s typical climate conditions.
