This video resource from Paul Anderson of Bozeman Science provides a comprehensive introduction to renewable energy and focuses on six technologies: biomass, hydroelectric, solar, geothermal wind, and hydrogen. The speaker frames the whole discussion with the idea that energy needs to be renewable and sustainable, highlighting issues with burning wood biomass and the myriad environmental disruptions often caused by hydroelectric generation. After a brief introduction featuring an excellent flow chart, the resource details the six renewable technologies, comparing each based on energy returned over energy invested. This simple economic ratio provides a good indication of the viability of each technology. Teachers may find it helpful to discuss with students what other considerations are consequential aside from economics. The video closes with a return to the flowchart, this time with some spaces left blank so that teachers can pause the video at 8:40 and get students to fill in the blanks. This video features clear narration and is recommended for teaching.
