About the Science
- NREL scientists introduce and review the problems of biomass energy and how they are working to solve those problems.
- A video about the principles of converting biomass to liquid transportation fuels.
- The video is somewhat dated, making references to President Bush's 2006 State of the Union Address. Government policy with regards to biofuels is now different from what it was when this video was made.
- Comments from expert scientist: This video presents NREL scientists's effort to made ethanol from cellulose and hemicellulose. These are the fibrous material that are abundant in nature and make up the bulk of most plant matter.
- The goal is generating Bio-fuels to address the energy crisis.
About the Pedagogy
- The video is embedded in NREL's Learning about Renewable Energy - Biofuels page. It is one page in their Learning sequence.
- There is mention of how current research is working on ending the "fuel vs. feed" debate, which raises the question of whether food crop biomass should go toward feeding people or making biofuels.
