Biofuel
From Conservapedia
Biofuel (pronounced bye-oh-FYOOL) is fuel made up of biological raw materials, such as wood or ethanol. This type of fuel is considered to be more friendly to the environment.[1]. The main type of biofuel available in America is corn-based ethanol. This is added to gasoline as an anti-knock compound, it replaces previously used compounds like tetramethyl lead and MTBE.
Some biotechnology companies are pursuing techniques to produce gasoline from algae[2].
