Advantages Of Geothermal Energy
Here we shall discuss the advantages of geothermal energy regarding geothermal energy plants (power stations.)
We can generate geothermal energy by drilling deep holes into the earths crust pumping cold water through one end and then by the time it rises back to the surface the water can be hundreds of degrees Celsius which we then use as steam to drive a turbine which drives a generator creating power. Geothermal energy is one of the best natural energies around.
So the first advantage of using geothermal heat to power a power station is that, unlike most power stations, a geothermal system does not create any pollution. It may once in a while release some gases from deep down inside the earth, that may be slightly harmful, but these can be contained quite easily.
The cost of the land to build a geothermal power plant on, is usually less expensive than if you were planning to construct an; oil, gas, coal, or nuclear power plant. The main reason for this is land space, as geothermal plants take up very little room, so you don't need to purchase a larger area of land. Another factor that comes into this is that because geothermal energy is very clean, you may receive tax cuts, and/or no environmental bills or quotas to comply with the countries carbon emission scheme (if they have one).
No fuel is used to generate the power, which in return, means the running costs for the plants are very low as there are no costs for purchasing, transporting, or cleaning up of fuels you may consider purchasing to generate the power.
The overall financial aspect of these plants is outstanding, you only need to provide power to the water pumps, which can be generated by the power plant itself anyway.
So if geothermal power stations are able to provide an excellent source of clean, cheap, simple, renewable power, why isn't every power plant in the world using geothermal energy? Well to go with the advantages are some very decisive disadvantages of geothermal energy.
