Thought the Prez was just kidding about those alternative fuel initiatives? Think again. Just hours after stating that the US government fleet would be 100 percent alternative fuel, hybrid, or electric vehicles by 2015, Obama has announced the National Clean Fleets Partnership, an initiative of the Department's Clean Cities program. It's a rather unique public-private partnership, and it'll be assisting large companies to "reduce diesel and gasoline use in their fleets by incorporating electric vehicles, alternative fuels, and fuel-saving measures into their operations."
