Biofuels are fuels produced from living organisms such as plants or microalgae. Examples of biofuels include:
- Bioethanol – An alcohol made from the fermentation of starch-rich and sugar-rich crops such as corn or sugarcane.
- Biodiesel – Produced using transesterification of oils and fats and is not too dissimilar to conventional diesel.
- Biofuel gasoline – A relatively new discovery, UK scientists have developed a gasoline fuel from Escherichia coli thats transforms glucose into biofuel.
