The U.S. Department of Energy (DOE ) has proposed a rule that would require federal agencies to cut the amount of petroleum they use in vehicle fleets, while at the same time increasing their use of alternative fuels. 77 Fed. Reg. 14,482 (3/12/12).
Under section 142 of the Energy Independence and Security Act of 2007, the energy secretary was directed to issue regulations that would reduce petroleum consumption and increase alternative fuel consumption in federal fleets. DOE has proposed that by fall 2015 federal agencies reduce annual petroleum consumption in their fleets by 20 percent from 2005 levels. Over the same period, the rule would require federal agencies to increase annual alternative fuel consumption by 10 percent. In addition to hybrid or electric vehicles, the rule would allow the use of vehicles fueled by compressed natural gas, ethanol or other biofuels. DOE will accept comments on the proposed rule until April 11, 2012.
