A type of biofuel made of alcohol and produced by fermenting sugars in plants such as corn or sugarcane; it is often blended with gasoline.

Ethanol is the alcohol-based biofuel produced by fermenting sugars from plants such as corn or sugarcane, and it’s commonly blended with gasoline. Yeast converts the sugars into ethanol, which is then refined to fuel-grade form. Because ethanol mixes well with gasoline, it’s used in blends like E10 or higher percentages in some regions, helping reduce reliance on pure fossil fuel.

Biodiesel, by contrast, comes from oils or fats and is used in diesel engines. Biogas is mainly methane produced through anaerobic digestion, not an alcohol. Hydrogen is a clean energy carrier, not a fermentation-derived alcohol. So the description specifically points to ethanol.
