Alternative fuel

Alternative fuel is any method of powering an engine that do not involve petroleum (oil). Some alternative fuels are electricity, hithane, hydrogen, natural gas, and wood. The need for the development of Alternative fuel sources, has been growing because of concerns that the reserves of oil are finite and will one day run out completly. See Oil depletion. The relative difficulty in obtaining oil which is a major cause of conflict, especialy in areas like the Middle East, has caused the price of oil to slowly rise. See Oil_price_increases_of_2004_and_2005. Growing concerns about the effects of polution from car exhausts and the Greenhouse effect have increased interest in Alternative Fuels, as well. See Future energy development for a general discussion.
