what is geothermal
What Is Geothermal?
  • Pertaining to the internal heat of the earth.
how it is obtained
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.
positive aspects
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.
negative aspects
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.
