Background

  • Alternative transportation is defined as a mode of transportation that does not require the use of conventional petroleum-based fuel sources, such as gasoline or diesel. Mass transit vehicles that do not use petroleum-based fuel, such as some trolley cars and buses, are considered alternative forms of transportation. No-emission forms of transportation, such as walking or bicycling, are also classified as forms of alternative transportation.
  • Other forms of alternative transportation include railroads, bus lines, subways, trolleys, and group commuter travel vans that are powered by alternative, nonpolluting fuels.
  • Alternative motor vehicles, agricultural equipment, airplanes, trains, and ships have modified engines that use alternative fuels, which are specifically manufactured to reduce the emissions typically found with the burning of traditional diesel or gasoline. These lowered emission fuels include electricity, biodiesel, compressed fossil natural gas (a combustible mixture of hydrocarbon gases, consisting of mostly methane), liquefied fossil natural gas, alcohol-based fuels, and hydrogen.
  • The purpose of using alternative transportation is to decrease the numbers of vehicles that use polluting forms of fuel, such as petroleum-based fuel sources, and their resulting emissions. The use of alternative forms of transportation decreases the dependence on crude oil as a fuel source. Gasoline is refined from crude oil. Domestic oil production has been declining since the 1970s, while imported oil to the United States has increased 67%.
