Biyoetanol, or bioethanol, is a renewable energy source made from organic materials, primarily corn, sugarcane, and other plant materials. It is produced through fermentation, where sugars in these plants are converted into alcohol. Biyoetanol can be used as a fuel for vehicles, either on its own or blended with gasoline, helping to reduce greenhouse gas emissions. This alternative fuel is considered more environmentally friendly than fossil fuels because it can lower carbon dioxide levels in the atmosphere. Additionally, biyoetanol supports agricultural economies by creating demand for crops, promoting sustainable farming practices, and reducing dependence on non-renewable energy sources.
