Geothermal power

• Give 2 disadvantages of Geothermal Power

  1. Can only be used in specific locations
  2. the power stations are expensive to set up initially
• What is geothermal energy?

  The thermal energy generated and stored in the earth
• Where does geothermal energy originate from?

  1. the original formation of the planet
  2. the radioactive decay of materials like uranium deep inside the earth
• Give 3 advantages of geothermal power

  1. Renewable
  2. cheap once the power station is set up
  3. can be used to generate electricity or hot water directly
• Where can geothermal power stations be used?

  1. Areas with lots of heat under the ground such as volcanic regions
• Outline how geothermal power stations work

  1. In regions with naturally hot grounds/lots of volcanic activity
  2. If cold water is pumped down into the ground: it will be heated by hot rocks
  3. can directly use the heated water to our homes/allpw the water to heat up so much to turn into steam
  4. the steam can be used to turn a turbine - can drive a generator to produce electricity
