Geothermal energy

"This program explains the dynamics involved in using geothermal resources, explores the prerequisite structure below the earth's surface which allows them to be tapped and examines methods for turning them into useable energy."@en
"The earth's interior provides a great deal of heat, which can be captured for man's use. Students will explore the prerequisite structure below the earth's surface that allows geothermal sources to be tapped, examine several different methods for translating geothermal reserves into usable energy, and visit locations in England, France, and Italy, where the process is being used."
"Describes the various sources of geothermal energy, such as ground water heated by volcanic rock, geothermal wells of dry steam and dry heat mining. Shows how geothermal energy is used for heat and generation of electricity."@en
