Ethanol is a type of alcohol that is commonly used as a fuel additive in vehicles. It is made from plants, such as corn or sugarcane, through a process of fermentation. Ethanol is mixed with gasoline to create a fuel blend that burns more cleanly and reduces harmful emissions. It is used in many cars, especially in areas where cleaner fuels are encouraged. Ethanol can also be used on its own as a fuel in some vehicles designed for it. It is considered an alternative to pure gasoline because it is renewable and produces fewer pollutants.
