May 7, 2013 | Number of The Day

There are quite a few alternative fuel vehicles in use in the Garden State, since the U.S. Department of Energy estimates that in 2011 there were 29,712 of them on the road in New Jersey — not including gasoline or diesel-fuel hybrids.

The federal DOE only includes vehicles that use an alternative fuel as their major source of energy. So plug-in electrics are considered alternative fuel vehicles, while regular hybrids are not.

The most common types of alternative vehicles in the state are those that rely on E85, or 85 percent Ethanol. Nearly 22,000 E85 vehicles are in use in New Jersey, followed by compressed natural gas (3,885), and liquid petroleum gas (3,109). In 2011, there were 314 vehicles fueled by electricity.

Most of these vehicles are owned by individuals (20,549). State (4,860) and federal (3,573) agencies owned most of the rest.
