Biofuels: Alternative Energy Supply

Biofuels: Alternative Energy Supply offers a solid overview of the role of biofuels as a vital component in the shift towards sustainable energy. Beginning with a short history of humankind's fuel consumption, the program points out the disadvantages of fossil fuels (which not only create pollution but are also finite resources—both of which lead to various social and political problems) before introducing the five major types of biofuels—biogas, ethanol, butanol, vegetable oils, and biodiesel. Viewers will learn how each is produced (as well as their byproducts and uses), along with relevant vocabulary and chemical formulations (i.e., butanol is C4H10O). While both the advantages and disadvantages of producing and using biofuel are addressed, biofuels are here presented in a generally positive light—as a necessary consideration for a world that is quickly depleting its fossil fuel stores.
