In this activity, students learn about the pros and cons of co-firing woody biomass fuels with coal to produce electricity.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Good tips are included in the lesson.
Worksheets with a wealth of resources are provided.
As coal-burning power plants seek ways to reduce their carbon dioxide emissions, some are evaluating co-firing with woody biomass for the generation of steam heat and/or electricity.
Passed initial science review - expert science review pending.
This is a problem-based authentic assessment.
Students assume the role of various stakeholders and participate in a discussion with classmates who represent officials from a local power plant that is seeking to substitute twenty percent of its coal with woody biomass.
Students evaluate available woody biomass options (forest residue, mill residue, urban wood) and come to a group consensus about which option, if any, is best from economic, environmental, and public health perspectives.
Very engaging and well-designed format.
Activity focused on the standards set by the North Carolina Renewable Energy Portfolio Standard REPS but can be easily adapted to other locations.
Easy-to-use lesson plan.
