  1. Geothermal Power

  2. What is Geothermal Energy? • Geothermal Energy is heat that comes from within the earth. • The heat in the center of the earth is continuously flowing outward.

  3. Geothermal Energy in the US • Alaska • Utah • Nevada • California • Idaho • New Mexico • Hawaii From above clockwise: California(1), Hawaii(4) & Alaska(2)

  4. How is Geothermal Energy Recovered • Magma carries heat from the center of the earth. • Heat is transferred to underground reservoirs in three forms • Dry Steam • Wet steam • Hot water • Reservoirs close to the surface can be drilled into.

  5. Uses of Geothermal Power • In ancient times the hot mineral springs have been used for bathing, cooking and heating. • They also felt that mineral rich waters was a natural way to heal.

  6. What will it heat? • Electrical • Replaces coal • Reduces pollution • Saves non-renewable resources

  7. What can bring it to Michigan? • It already exists in Michigan • Many people can get it in their home • Niles Michigan

  8. Likeliness of becoming mainstream -vast potential supply (renewable) -22 countries, 1% -U.S.A, 38% -The Geysers: 26 plants, 1.3 million Heat withdrawn 80X faster -research: hot-dry rock zones Cost $$$ U.S Geothermal Energy Association: 5% of needs

  9. Advantages vs. Non-renewable • Cleaner • Helps conserve non-renewable sources • Easy on the Land • Reliable • Saves money • Helps developing countries grow

  10. Pros and Cons (challenges)
