6.10 Geothermal Energy

Describe the use of geothermal energy in power generation.

• Geothermal energy is obtained by using the heat stored in the Earth’s interior to heat up water, which is brought back to the surface as steam. The steam is used to drive an electric generator.
• Enduring understanding ENG-3: Humans use energy from a variety of sources, resulting in positive and negative consequences.

Describe the effects of the use of geothermal energy in power generation on the environment.

• The cost of accessing geothermal energy can be prohibitively expensive, as is not easily accessible in many parts of the world. In addition, it can cause the release of hydrogen sulfide.
• Enduring understanding ENG-3: Humans use energy from a variety of sources, resulting in positive and negative consequences.
