How is biofuel energy made?


Answer: Biofuels come from a biological origin, like plants. Plants take in solar energy from the sun and nutrients from the soil and store it in its leaves, stems, roots, and other organic matter. Biofuel is made by harvesting the organic matter and adding microorganisms capable of braking down the organic material by converting it into a usable fuel much like fossil fuels. This process, called fermentation, involves yeast cultures that are capable of fermenting a specific part organic material like sugars and starches. Currently, most industrial biofuel is in the form of ethanol, or bioethanol,and is fermented from corn. Modern advancement aims at developing new yeast cultures capable of fermenting starches from different organic materials, like plants that can be grown with a smaller environmental impact then corn.
