There are couple of numbers for geothermal energy advantages and disadvantages. Well, please have a read!
Geothermal Energy Advantages
There are many advantages to geothermal energy. Geothermal energy is renewable energy because once water or steam is used, it can be pumped back into the ground
1. Significant Cost Saving
Geothermal energy generally involves low running costs since it saves 80% costs over fossil fuels and no fuel is used to generate the power. Since, no fuel is require so costs for purchasing, transporting and cleaning up plants is quite low.
2. No Pollution
This is one of the main advantage of using geothermal energy since it does not create any pollution and help in creating clean environment. Being the renewable source of energy, geothermal energy has helped in reducing global warming and pollution. Moreover, Geothermal systems does not create any pollution as it releases some gases from deep within the earth which are not very harmful to the environment.
3. Direct Use
Since ancient times, people having been using this source of energy for taking bath, heating homes, preparing food and today this is also used for direct heating of homes and offices. This makes geothermal energy cheaper and affordable. Although the initial investment is quite steep but in the long run with huge cost saving it proves quite useful.
4. Job Creation and Economic Benefits
Government of various countries are investing hugely in creation of geothermal energy which on other hand has created more jobs for the local people.
Though above said advantages prove that geothermal energy has big capability in itself in creating clean and safe environment and also it is an excellent source of cheap, reliable, simple, clean and renewable power but it also suffers from few drawbacks which is why it is not being utilized everywhere to its full capability.
Geothermal Energy Disadvantages
Energy created from geothermal power is safe, clean, simple, reliable and environment friendly as it is extracted from deep within the earths surface. But despite these advantages, geothermal energy is not being used widely. Geothermal energy suffers from its disadvantages as described below.
1. Not Widespread Source of Energy
Since this type of energy is not widely used therefore the unavailability of equipment, staff, infrastructure, training pose hindrance to the installation of geothermal plants across the globe. Not enough skilled manpower and availability of suitable build location pose serious problem in adopting geothermal energy globally.
2. High Installation Costs
To get geothermal energy, requires installation of power plants, to get steam from deep within the earth and this require huge one time investment and require to hire a certified installer and skilled staff needs to be recruited and relocated to plant location. Moreover, electricity towers, stations need to set up to move the power from geothermal plant to consumer.
3. Can Run Out Of Steam
Geothermal sites can run out of steam over a period of time due to drop in temperature or if too much water is injected to cool the rocks and this may result huge loss for the companies which have invested heavily in these plants. Due to this factor, companies have to do extensive initial research before setting up the plant.
4. Suited To Particular Region
It is only suitable for regions which have hot rocks below the earth and can produce steam over a long period of time. For this great research is required which is done by the companies before setting up the plant and this initial cost runs up the bill in setting up the geothermal power plant. Some of these regions are near hilly areas or high up in mountains.
5. May Release Harmful Gases
Geothermal sites may contain some poisonous gases and they can escape deep within the earth, through the holes drilled by the constructors. The geothermal plant must therefore be capable enough to contain these harmful and toxic gases.
Geothermal Energy can not be easily transported. Once the tapped energy is extracted, it can be only used in the surrounding areas. Other sources of energy like wood, coal or oil can be transported to residential areas but this is not a case with geothermal energy. Also, there is a fear of toxic substances getting released into the atmosphere.
