Geothermal energy is an alternate source of energy. This kind is generated deep within the surface of the earth. Geothermal is a term that comes from two Greek words, geo which means earth and thermos which means heat. Therefore with this power source we are able to generate electricity.
The heat is produced within the earth, far below the surface but it finds its way to the surface and comes out in the form of hot water springs, volcanoes and geysers. Geothermal plants are built for the sole purpose of accessing this heat. There are pipelines that are used to tap the steam from inside the earth. The steam is then used to rotate turbines that generate electricity.
There are various advantages and disadvantages of using this power source. The key advantage is that the process of generating it does not involve the burning of fossil fuels. It is basically a clean process. The power plants themselves are also environmentally friendly.
This type of power resource can not be exhausted because it is constantly being produced deep within the surface of the earth. Therefore the steam will always be more than enough as long as it can be harnessed. It is also quite effective because the costs are relatively low.
The main disadvantage when it comes to geothermal power is that of availability. Although the heat is continuously being generated beneath the surface of the earth, finding the right spot to make use of it on the surface is not simple. When the system is up and running you will find that the costs will be very low since the steam is free. However the start up costs is very high.
To add on to that even though there is no burning of fossil fuels, when tapping the energy there is a chance that you might cause other things to happen. There are methane deposits that are also beneath the surface of the earth. They might be disturbed somehow. If this situation occurs the methane could be released into the atmosphere and add to the greenhouse effect.
One fact that is noteworthy is that the geothermal energy resource is so colossal that it is more than uranium, gas and coal merged together. This type of energy is mostly used in Iceland and the Philippines. If you are one of those individuals who are kin on reducing the emission of harmful gases into the atmosphere, you could actually consider changing to this kind of power source.
