Geothermal energy

  1. 1. Origin of Geothermal Energy
  2. 2. Different Geothermal Energy Sources
  3. 3. How Direct Use Work Direct Sources function by sending water down a well to be heated by the Earth’s warmth. Then a heat pump is used to take the heat from the underground water to the substance that heats the house. Then after the water it is cooled is injected back into the Earth.
  4. 4. Direct Application of Geothermal Energy
  5. 5. Generation of Electricity Dry Steam Plant Flash Steam Plant Binary Cycle Plant Hot Dry Rocks
  6. 6. Homegrown Energy Geothermal Heat Pumps Low maintenance charge produces 4 times the energy that they consume Can be online 90-100% of the time Less gaseous emissions Good Alternative to Fossil Fuels Electricity generated by geothermal plants saves 83.3 million barrels of fuel each year Direct use of geothermal energy prevents 103.6 million barrels of fuel each year Positive Attributes
  7. 7. Geothermal’s Harmful Effects
  8. 8. CARBON DIOXIDE EMISSIONS per unit of energy produced Comparison of CO2 emissions between conventional energy systems and geothermal plants to generate electricity.
  9. 9. Comparison of harmful emissions between a conventional oil fired central heating system and water/water based heat pumps
  10. 10. Conclusion • As of 2010 geothermal energy is being used in 24 countries. • These countries currently have geothermal power plants with a total capacity of 10.7 GW • But 88% of it is generated in just seven countries: the United States, the Philippines, Indonesia, Mexico, Italy, New Zealand, and Iceland
