Biofuels and Fossil Fuels

Biofuels are a potential environmentally friendly substitute for fossil fuels this where there strengths lies. The two most remarkable first generation biofuels are bioethanol and biodiesel. Other 1st generation biofuels comprises butanol, alcohol and biogas. The 2nd generation of biofuels make use of innovative technology like gasification and liquefaction technique to change biomass into biofuel. Bio-fuels are a potentially more environmentally friendly substitute for fossil fuels and this is naturally where their strengths lie. The latest focus on so called third generation biofuels focuses on algae. Bioethanol is an alcohol-based fuel made through the fermentation of crops such as barley, wheat, corn or sugar cane. It is the most commonly used biofuel worldwide. Fossil fuel is made by natural process, formed from dead organisms. Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas. Other mostly used derivatives include kerosene and propane. During the process of combustion, pollutants such as carbon dioxide and nitrous oxide are emitted and enter the atmosphere. These contaminants are called greenhouse gases.
