How does Geothermal Energy Work?
- Heated water is harnessed from the Earth using a heat pump.
- Steam is later created by the heated water.
- The steam is used to power electrical generators, producing electricity.
- The water is later cooled.
- The water returns into Earth to replenish water supply.
How does Geothermal heating system work?
- Cool Water is sent down the pipe from the heat pump
- The water is heated and travels back upwards
- The heat is collected and distributed throughout the household
- The water is cooled and sent back down the pipe
- 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
