Biofuels are already being made from all types of sources, from palm oil to sugarcane to switchgrass. Growing our own energy is certainly an appealing proposition. But, how much can we really expect to produce this way? How can we produce biofuels without impacting food crops (see tortilla riots)? In this module you will evaluate the potential contributions of biofuels to our energy mix.
