Sugarcane ethanol is a type of biofuel produced from the fermentation of sugars found in the stalks of sugarcane. This renewable energy source is primarily used as an alternative to gasoline in vehicles, helping to reduce greenhouse gas emissions and reliance on fossil fuels. The process of making sugarcane ethanol involves harvesting the sugarcane, extracting its juice, and then fermenting that juice with yeast. Countries like Brazil are leaders in sugarcane ethanol production, utilizing vast plantations to create a sustainable energy source that can power cars and contribute to energy security.
