With a growing reliance on fossil fuels, sources are depleting quickly and greenhouse gas emissions are skyrocketing. In order to lower consumption, alternative sources must be found. Alternative fuels are defined as vehicular fuels that are not entirely obtained from petroleum. This website will focus on the following four alternative fuels and their many factors.
Biodiesel is a liquid fuel that is used to fuel compression-ignition engines. It is composed of mono-alkyl esters of long chain fatty acids. It can be domestically produced from vegetable oils, animal fats, or waste trap grease and is a much cleaner alternative to petroleum because it is nontoxic and biodegradable. |
While many believe the use of alcohol based fuel is a new concept, it has actually been used in the automotive industry since the 19th century. Ethanol is a clear colorless liquid and is a renewable fuel produced from components known as biomass. More than 95% of the U.S’s gasoline contains an ethanol blend. |
