  1. Fuel for diesel engines made from renewable organic raw materials, as opposed to fossil hydrocarbons.

    Biodiesel is an increasingly popular alternative fuel because it's made by refining oil. Thinner than vegetable oil, biodiesel can power diesel engines without further conversion.

    Biodiesel is a technologically feasible alternative to petrodiesel, but nowadays biodiesel costs 1.5 to 3 times more than fossil diesel in developed countries.
