Alternative Fuels for Automobiles - Free Information

Alternative Fuels for Automobiles - Free Information

Vehicles that operate primarily on gasoline or diesel have historically accounted for over 99% of cars and passenger truck sales. Now, sales of cars that operate on alternative fuels like ethanol, natural gas, and electricity are growing. Millions of flexible fuel vehicles - vehicles that can run on either E85 (a mixture of about 85% ethanol and 15% gasoline) or gasoline - have been sold in the past decade.

Alternative fuels include gaseous fuels such as hydrogen, natural gas, and propane; alcohols such as ethanol, methanol, and butanol; vegetable and waste-derived oils; and electricity. These fuels may be used in a dedicated system that burns a single fuel, or in a mixed system with other fuels including traditional gasoline or diesel, such as in hybrid-electric or flexible fuel vehicles.

Some vehicles and engines are designed for alternative fuels by the manufacturer. Others are converted to run on an alternative fuel by modifying the engine controls and fueling system from the original configuration.

Many alternative fuels "burn" cleaner than gasoline or diesel so there are fewer tailpipe emissions. The amount of greenhouse gases (GHG) emitted when the fuel is produced depends on the source of the fuel - see GHG Emission for more information . These fuels can also be produced domestically, reducing our dependence on imported petroleum. Click on the tabs below to learn more about each fuel.
