Biofuel: An Alternative Energy Source

Abstract
As the world’s source of fossil fuels diminishes, another source of energy must replace fossil fuels. This paper evaluates biofuel, one alternative form of energy by showing what biofuel is, how it works, its historical use, and benefits and drawbacks it pertains. I hypothesized that biofuel would be an effective alternative energy. My conclusion does not support my claim, but in terms of worldwide usage.

Introduction:
With the world’s source of fossil fuels depleting, we need to find an alternative energy source. Biofuel is one considerable option. Although biofuel has not been used widespread, it has been used quite extensively in several countries. Such countries include Sri

History Biofuel usage has started since the 1800’s. Around this time, vegetable oils were used to purify glycerin used in soap production. ((n.d), 2003) Ethyl and methyl were by products of this process. They replaced many common oils as sources of complex fatty acids, which have biofuels as by product. Ethanol and methanol came from these two esters, and went into use. Methanol is currently preferred over ethanol because it can better be mixed with biodiesel, a currently used car fuel, than can ethanol. However, it is a bit more toxic than ethanol. Ethanol, which is harvested from corn and soybeans, is more widely in the Midwest. Around the late 1800’s, Rudolf Diesel demonstrated the first biodiesel made from peanut oil. Biodiesel is an alternative to petroleum and gases used in engines. In 1908, Henry Ford designed his automobiles to run on biodiesel, thinking it would be a major success. Biodiesel did quite well in sales until the industrial period of the United States in the 1930’s.
