Biodiesel and ethanol are both biofuels: fuels produced from organic matter. As global warming worsens and our oil supply dwindles, biodiesel and ethanol have both been touted as the fuels of the future. They are purported to be renewable, and clean.
Because these similarities, people frequently confuse ethanol with biodiesel, and vice versa. Ethanol and biodiesel are completely different substances, with completely different properties. For one, ethanol is an alcohol. It is the alcohol found in beer, wine, vodka, etc.
