  1. Geothermal Energy Power From the Earth

  2. Definition & Types • “The energy from heat in the Earth’s crust.” • Visible Features • Volcanoes, Hot Springs, Geysers, &Fumaroles • Four Main Types • Hydrothermal • Geopressured • Hot Dry Rock • Magma • Types Of Geothermal Plants • Dry Steam, Flash, & Binary

  3. Location • World’s Largest Development • “The Geysers” North of San Francisco, California • First Geothermal Plant in the Philippines • Capoocan, Philippines • Largest Geothermal Plant in the World • Cerro Prieto Geothermal Power Station (Mexico) • First Geothermal Plant • Larderello (Italy) • 1/5 Plants that Power 1/3 of Iceland • Reykjavik, Iceland Reykjavik, Iceland

  4. Resource Benefits • Cost Savings  Saves 80% • Less Fossil Fuel Usage • Less Pollution • Job Creation • Free Hot Water Generation

  5. Environmental Consequences • Damages to Natural Geothermal Features • Pollutes Waterways • Air Emissions • Subsidence • Depletes the Resources

  6. Resource Uses • Heat Greenhouses to Grow Vegetables in the Winter • Drying food/wood • Dying wool to extract gold and silver from ore • Geothermal Power Plants can be used as generators • Heat sidewalks and roads to keep from icing. (Netherlands)

  7. Costs • $15,000- $25,000 on Average • Save about $3,000 All Together • Propane Savings: A little over $3,000 • Cost of Operation Savings: $500 • Federal Tax Credit: $7,500 or 30% of the Cost

  8. Applicable Legislation • Clean Air Act • Geothermal Steam Act • Clean Water Act • Noise Control Act • Pollution Prevention Act

  9. Extra Facts • Geothermal means Earth-Heat • About 24 Countries Use Geothermal Power • Geothermal is the Main Energy Source in Iceland • The US has Geothermal Plants in 7 States • Geothermal Energy has Been Used Since Ancient Times • In Hot Water Form
