Hybrids use two or more power systems, such as a gasoline engine and an electric drive motor, to provide more efficient propulsion. Learn more about hybrids and what distinguishes them from other vehicles in Green Car’s section on hybrids.
Electric cars use one or more electric drive motors, powered by batteries, for zero-emission motoring. Electric cars are recharged by plugging into the grid.
Ethanol is an alcohol-based alternative fuel made from biomass. As a popular alternative fuel, ethanol is typically used in the form of E85 to power flex fuel cars outfitted specifically to run on this blend of 85% ethanol and 15% gasoline.
Hydrogen cars are among the cleanest cars on the road, emitting oxygen and water vapor only. Hydrogen is the cleanest burning of all liquid and gaseous alternative fuels.
Natural gas is a clean-burning alternative fossil fuel that can easily power internal combustion engine vehicles. The domestic abundance of natural gas makes it a highly attractive alternative fuel option.
Plug in hybrids get high MPG, cover many miles on battery power alone, and include a gasoline engine to provide greater range as needed. Plug in hybrids are mostly recharged from the grid, but some plug-in hybrid models can generate electricity when using
As a leading alternative fuel, biodiesel can be made from various sources including soybeans and biomass. Biodiesel can be used in most diesel powered cars without modification.
Air powered cars are relatively new to the green car scene. Compressed air is currently being explored as a viable 'alternative fuel' to efficiently power car engines with little or no environmental impact.
