Fact #682: July 4, 2011
Federal Alternative Fuel Use

The Federal Government used nearly 9 million gasoline-gallon equivalents of alternative fuel in 2010. The majority of the fuel used (92%) was E-85, a combination of 85% ethanol and 15% gasoline. The Government's use of liquefied petroleum gas (LPG), compressed natural gas (CNG), and liquefied natural gas (LNG) has declined over the last few years. In 2010, electricity use grew due to a large acquisition of electric vehicles for the Federal fleet.
