Simply put, biofuel is any fuel derived from biomass - that is, any recently living organisms or their metabolic byproducts. It could be oils from plants, manure from cows, wood, etc. It is a renewable energy source, unlike other natural resources such as petroleum or coal. In addition, the carbon in biofuels was recently extracted from atmospheric carbon dioxide by growing plants, so burning it does not result in a net increase of carbon dioxide in the Earth's atmosphere.

The production of biofuels to replace petroleum-based oil and natural gas is in active development. This alternative to the continued use of fossil fuels is exciting because it provides us with easily available fuel that can fit into today's gasoline and diesel engines with minimal or no changes to existing systems.

A couple of advantages of biofuels are:

• Significantly fewer noxious emissions than petroleum-based fuel when burned
• Biodegradable
• Non-toxic
• Renewable
