The conventional gasoline-electric hybrid came in second, with available vehicles listed at 261,312. Compressed natural gas vehicles were third (3,770) and electric-only autos placed fourth (2,255). Down at the bottom of the EIA's list, with only 26 units made available in 2009, is the hydrogen-fueled vehicle.
The Energy Policy Act of 1992 mandates that the EIA annually collects data on alternative-fueled vehicles made available in the U.S. by automakers and that it estimates the number of alt-fuel vehicles in use in the States. Anyone got guesses for the 2010 and 2011 numbers?
