Many new vehicles have been developed such as the electric
vehicles that run on batteries, the hybrid vehicles that run
on both an electric motor and a gasoline engine and the newest
invention the fuel cell vehicle. In addition many gasoline cars
and trucks have ben converted so they can operate on ethanol,
natural gas or other alternative fuels.
Alternative fuels are defined by the Energy
Policy Act of 1992 (EPAct). It includes fuels that can be
used to power vehicles that are not solely based on fossil oil
for their manufacture. Although there are plenty of oil reserves
on the planet at the moment, at the rate we are using them primarily
to power cars and trucks, we will eventually run completely
out of fossil oil and it takes thousands of years to create
more of them.
The fuels defined by the EPAct include ethanol, natural gas,
propane, hydrogen, biodiesel, electricity, methanol, and p-series
fuels. All of these fuels are being used around the world for
a variety of purposes and to power all kinds of vehicles.
Most alternative fuels reduce the amount of pollution in our
atmosphere caused by harmful pollutants from exhaust emissions.
Many of these alternative fuels can be produced from renewable
sources such as grain and other plants.
