  1. Geothermal Kristi Hall Rosa Money SanQuanetta Tarbert

  2. History • Ancient Romans used hot springs to heat baths and homes. • Similar uses are still found in Iceland, Turkey, and Japan. • It’s greatest potential lies in the generations of electricity. • It was first used to produce electric power in Italy in 1904.

  3. What Is Geothermal? • Pertaining to the internal heat of the earth.

  4. How It Is Obtained? • Engineers have learned how to pump this water up, turn it into steam, and use it to heat buildings or turn a turbine to produce electricity. • When the steam is turned back into water and sent back down into the earth we have source of renewable energy. • Most geothermal resources are in regions of active volcanism. • Hot springs, geysers, pools of boiling mud fumaroles are the most easily exploited sources.

  5. Positive Aspects • Energy can be extracted w/o burning a fossil fuels. (clean) • Geothermal energy is available 24hrs. a day. • It is also homegrown, reducing our dependence on foreign oil.

  6. Negative Aspects • Large scale operations quickly use up available geothermal energy. • The heat use is replaced very slowly. • Excessive use of the resource depletes it. • It can be tapped in a few places.
