- A good video to include in any unit that addresses how to reduce greenhouse gas emissions. Educator could introduce cost/benefit analysis of ethanol as a fuel as well as social and economic challenges.
About the Science
- This video goes over the pros and cons of using ethanol as an alternative to gasoline.
- Discusses issues such as how converting corn into ethanol requires a lot of energy and reduces stocks of corn that might otherwise be used to feed people and livestock.
- Shows research efforts to use cellulosic biomass and microorganisms to accomplish the conversion from plant matter to fuel in a single step.
- Comments from expert scientist: The combination of the video with the Background Essay is helpful - i.e. the essay goes into a little more depth than the video, which aids in understanding the full reasoning behind using cellulosic biomass to make ethanol.
