America's use of alternative fuels for transportation rose about 13% from 2010 to 2011, according to the latest report from the U.S. Energy Information Administration.
The EIA says vehicle consumption of such fuels which include natural gas, propane, ethanol, hydrogen and electricity reached nearly 516 million gasoline-equivalent gallons (geg).
Natural gas accounted for nearly half the total. Ethanol and propane contributed roughly 25% each. Consumption of electricity in light-duty vehicles jumped to 7.6 million geg from 4.9 million geg in 2010.
The EIA says consumption of traditional fuel was virtually unchanged between 2007 and 2011. The use of replacement fuels such as biodiesel and ethanol grew from about 6 million geg to nearly 10 million geg over the same period.
Federal agencies operated nearly 176,700 alternative-fuel vehicles in 2011, according to EIA's report. The U.S. Postal service, with 44,400 units, represents the largest fleet, followed by the U.S. Army with 28,700 vehicles and the Dept. of Homeland Security with 16,900 units.
