Science geothermal energy

• The oldest geothermal technology takes steam out of fractures in the groun and uses it to directly drive a turbine and they are the simplest design

  Dry steam power plant
• Extremelt hot water is rapidlt depressurized or flashed into steam it is then used to drive the turbine


  Flash steam power plant
• The hot water is passed by a secondary fluid with a much lower boiling point than water,the isobutane boils at a lower temperature and its ateam runs the turbine

  Binary cycle power plants
• Considerably safer than most other energy sources,it does not produce greenhouse gases,used for heating and cooling purposes

  Geothermal energy
• Advantages of geothermal energy

  Good for environment

  Renewable energy

  Have high efficiency

  there is no maintinance

  Unlimited supply
• The extraction of geothermal energy causes green house emmisions

  Disadvantages
• Geothermal energy is a reliable slurce of renewable energy

  Advantages
• Hot water is pumped from deep underground through a well under high preassure

  1
• Hot water is pumped from deep underground through a well under high preassure
• When the water reches the surface rhe pressure is dropped,which causes thw water to turn into steam
• The steam spins a turbine,which is connectex to a generator that produces electricity

• The steam cools off in a cooling tower and condenses back to water


  4
• The steam cools off in a cooling tower and condenses back to water
• The cooled water is pumped back into the earth to begin the process again
