The New York Times has an audio slideshow that provides a brief overview of geothermal energy. The audio slideshow is the accompaniment to an article about the dangers of drilling deep into the Earth. The slideshow provides an explanation of why the western United States is one of the easier places to access geothermal energy. The slideshow offers good visual aids depicting how geothermal energy is harnessed.
Applications for Education
This audio slideshow could be useful for science teachers to use as an introduction to geothermal energy. The slideshow could also be the beginning of a student brainstorming session in which they list all of the forms of alternative energies with which they are familiar.
