Geothermal Energy: Harnessing the Power of the Earth
http://www.pbslearningmedia.org/resource/kqedcl11.sci.ess.geothermalenergy/

KQED, Teachers' Domain

This video describes how geothermal heat resources in California have been tapped to supply 850 MW of electricity. Images and animations show how the area known as The Geysers has been developed to capture steam, produced from trapped rainwater and heated by the earth. Major challenges include finding suitable geothermal resources to develop, and ensuring that underground water is replenished.

Video length 7:36 min.

Energy Literacy

Humans transfer and transform energy from the environment into forms useful for human endeavors.
Other materials addressing:
4.1 Humans transfer and transform energy.
Different sources of energy and the different ways energy can be transformed, transported and stored each have different benefits and drawbacks.
Other materials addressing:
4.7 Different sources of energy have different benefits and drawbacks.
Water plays a major role in the storage and transfer of energy in the Earth system.
Other materials addressing:
2.4 Water stores and transfers energy.

Benchmarks for Science Literacy

Energy from the sun (and the wind and water energy derived from it) is available indefinitely. Because the transfer of energy from these resources is weak and variable, systems are needed to collect and concentrate the energy.

Teaching Tips

  • After viewing this video and associated materials, students could explore other areas of the country (or world) that are utilizing or developing geothermal energy sources.

About the Science

  • Video explains how geothermal energy is tapped, converted to steam, transported to generators, and and converted to electricity.
  • Comments from expert scientist: Highlights challenges with drilling, including its high cost. Focuses on geothermal steam power plants, which are rare.
