Geothermal

• Geothermal power


  Thermal energy generated and stored in the earth's crust
• Geothermal energy


  • Heat energy originated from the initial formation of our planet
  • Heat energy originated from the ongoing radioactive decay of materials like uranium deep inside the earth
• Using geothermal energy for heating

  1. Pump water down into the ground

  2. Allow water to warm up

  3. Pump water back up to the surface to heat homes
• Using geothermal energy to generate electricity

  1. Leave water underground until it heats up to steam

  2. Steam rises and turns turbines

  3. Turbines drive generators to produce electricity
• Geothermal power plants


  • Can only be used in certain areas such as volcanic regions where hot rocks lie near the surface
  • Can be quite expensive to build
• Geothermal energy


  • Damages the environment very slightly when installing the plant
  • Doesn't produce any pollutants like carbon dioxide when running
  • Is a renewable resource
  • Is reliable over long periods
