According to Treehugger, Wal-Mart stores is backing the design and production of a Hybrid Peterbilt Semi-Tractor.
According to Peterbilt:
The heavy duty hybrid electric Model 386, configured for on-highway use, is being developed in conjunction with Eaton and Wal-Mart Stores, Inc. It is currently in the testing and evaluation phase and is expected to be available in 2010. Wal-Mart, which operates the nation’s second largest private fleet, is supporting development by helping validate the concept and refine the final design.
During third-party testing, the Eaton Hybrid Power System has routinely achieved a 5-7 percent fuel savings versus comparable, non-hybrid models.
I also read recently that Wal-Mart is changing the lighting in their store coolers to LED lights vs. incandescent or CFLs to save a bunch of money on bulb replacements and energy costs.
