Teaching Materials
Positives
- Diagrams and animations are used to help explain the concept in a clear way.
- The video is optimistic about geothermal energy and how it could help reduce our reliance on fossil fuels.
Prerequisites
- Students should be familiar with the terms renewable energy and clean energy.
Differentiation & Implementation
- This video can be used in a science class when learning about Earth's interior and could be combined with this map of energy resources in the U.S. to investigate where it is possible to use this and other types of energy.
- In a physical science course, students can further research the mechanics used in the geothermal plants to convert heat energy to electricity.
- Other resources about geothermal energy include this NowThis Earth video, this video about geothermal energy in Iceland, and this TED video.
- Other resources about renewable sources in general include this e-book and this video about technology solutions.
This resource introduces the common methods of harnessing geothermal energy. For instance, the dry steam, flash steam, and binary cycle methods are efficient and renewable technologies that can contribute to the renewable energy portfolio globally if given appropriate attention for improvement and scalability. The methods are scientifically proven, and this resource is recommended for teaching.
