Chances are the Secret Service won't be ditching its signature black SUVs for these things anytime soon, but if all goes according to President Obama's new energy plan, even the Commander in Chief's armed guards will be rolling more eco-friendly in the next three years. In a speech given at Georgetown University Wednesday, the President said he expects all government agencies "to purchase 100 percent alternative fuel, hybrid, or electric vehicles by 2015." Now, that doesn't mean they'll have to get rid of pre-existing gas guzzlers, but any new purchases made after the cutoff date will be expected to comply -- the government's current fleet consists of 660,000 vehicles, 400,000 of which run on gasoline. Among other things, the President also called for increased infrastructure for the production of biofuels made from things like wood chips and switchgrass. So no, Cadillac One probably won't be replaced by a rechargeable egg car, but if Uncle Sam's taking suggestions, we'd be happy to make a recommendation -- Wheego Whip LiFe One does have a nice ring to it. Doesn't it?
