Geothermal: Taming the Fireball.

This video is one of a series of videos from the Switch Energy project. It describes three types of geothermal sources -- rare ones in which high temperatures are naturally concentrated near the surface, deep wells that require fracturing the rock and then circulating water to bring heat to the surface, and low temperature sources that use constant temperatures just below the surface to heat or cool a building. The latter two are more widely available but cost-prohibitive today.

Teaching Tips

Consider using the Switch Energy website [link http://www.switchenergyproject.com/about/the-project] to have students do a research project on the pros and cons of different types of energy sources. Then, as a class they can create an energy portfolio.

The webpage contains links to both excerpts and complete versions of the various interviews undertaken in this project. Students could explore how the excerpts relate to the complete interview to determine whether the excerpts do reflect the opinions of the interviewees.
