What is Geothermal Energy?

Geothermal Energy is the energy that is acquired from the natural heat of the earth's mantle. The thermal energy then can be used in many different manners, such as to heat or cool a building, or to power a generator to produce electricity.

How does Geothermal Energy Work?

  1. Heated water is harnessed from the Earth using a heat pump.
  2. Steam is later created by the heated water.
  3. The steam is used to power electrical generators, producing electricity.
  4. The water is later cooled.
  5. The water returns into Earth to replenish water supply.

How does Geothermal heating system work?

  1. Cool Water is sent down the pipe from the heat pump
  2. The water is heated and travels back upwards
  3. The heat is collected and distributed throughout the household
  4. The water is cooled and sent back down the pipe
  5. The same process can be reversed to produce cool air rather than warm air

Advantages of Geothermal Energy

  • Renewable energy source
  • Does not cause pollution
  • Very minimal energy and cost efficient when in operation
  • Does not require much space

Disadvantages of Geothermal Energy

  • You cannot set it up anywhere; location must be suitable, however many hotspots are available in Canada
  • Costly and can be hazardous to install and set up: however when set up, it becomes very cost efficient in the long run.
  • May release harmful gases, but very unlikely
  • May run out of steam to power the geothermal power station
