Biofuels, also known as agrofuel, consist of three forms: solids, liquids, and gases. Some types of biofuels are: vegtable oil, ethanol, and algae fuel. Some solar energy is captured using vegtable oil because plants capture sunlight for their photosynthesis. Ethanol is based off of the crop: corn. Ethanol is an alcohol that can be found in alcoholic beverages. Ethanol is a substitute for gasoline and it can power such things as cars. Algae fuel is farmed algae that is held under certain conditions to later be turned into fuel.
