Geothermal power

• Geothermal energy

  Thermal energy generated and stored in the Earth
• Where does geothermal energy originate from

  Original formation of the planet

  Radioactive decay of materials like uranium deep inside the earth
• How do geothermal power stations work

  1. In regions with lots of volcanic activity, the ground is naturally very hot
  2. If cold water is pumped into the ground it will be heated by the hot rocks
  3. The heated water can be used to directly heat our homes
  4. Or we can turn it into steam
  5. The steam can be used to turn a turbine which can drive a generator to produce electricity
• Where can geothermal power stations be used

  In areas with lots of heat under the ground, such as volcanic regions
• 3 advantages of geothermal power

  Its renewable

  It’s cheap once the station is set up

  Can be used to generate electricity of hot water
• 2 disadvantages of geothermal power

  Can only be used in specific locations

  Power stations are expensive to set up initially
