• Geothermal Heat Pump


  •Provide heat for buildings

  •Use heat coming from close to the Earth's surface
• Geothermal Power Plant


  •Generate steam to make electricity

  •Use heat from deep inside the Earth
• Process of Geothermal-Heat-Pump

  1. Ground source heat pump uses fluid to absorb heat from the ground
  2. Using electricity, the pump compresses the fluid and releases it at a higher temperature
  3. Heat is sent to radiators or under floor heating. The remainder is stored in a tank.
  4. Stored hot water can be used for showers,baths and taps
• Geothermal Power Plant

  1. Wells are drilled deep into the earth to pump steam or hot water to the surface.
  2. When the water reaches the surface, the drop in pressure causes the water to turn into steam.
  3. The steam spins a turbine, which is connected to a generator that produces electricity.
  4. Cooling tower cools the stearn which it condenses back to water.
  5. The cooled water is pumped back into the earth to begin the process again.
• Pros of Geothermal energy


  •Environment friendly •Renewable and sustainable •Creates more jobs •Cheaper
• Cons of Geothermal energy


  •Restricted location •Could trigger earthquakes
