A continuous debate is going on regarding the geothermal energy and the pros and cons of harnessing it. It helps greatly to understand the situation in better terms if we get to know exactly what geothermal energy is all about and why it is garnering so much of interest all over the globe.
Geothermal energy and how it has become possible
Though we are aware that below the earth’s surface it is extremely hot but if you know that about 4000 miles beneath the temperatures range above 7000 degrees Fahrenheit you will be truly shocked! Going that deep inside the earth’s surface is extremely dangerous but drilling just about 3 to 4 miles brings you to the hot rock which is not that hot but with only 300 to 400 degrees Fahrenheit and this can be utilized as a constant source of energy for us but this can prove to be really very expensive.
What can be done to circumvent this problem?
To circumvent this problem we have an alternative; in certain places just a few hundred feet beneath the earth’s surface the hot rock combined with underground water source produces hot water streams which turn out to be the most economic source of heat which can be used for various purposes such as heating homes and businesses, run large farms and commercial establishment or provide energy for greenhouses.
Geothermal energy pros and cons
Though geothermal energy offers a lot of benefits it also has a lot of concerns too and that is the reason for this debate on Geothermal Energy Pros And Cons.
When we talk about the main advantage we derive from geothermal energy which is reducing the ill effects on our environment the impact of this alternate source of energy has far more benefits than cons. There are absolutely no emissions with geothermal facilities and these factories also require lesser space that the other gas plants since these facilities do not necessitate underground pipelines to distribute fuel. Therefore geothermal energy can be considered a universal contributor to safer, cleaner and healthier environment.
Reliability and efficiency are the watchwords for geothermal energy; simple system, less problems, no waste disposal and no transport of fuel makes this system one of its kind and apt for the situation we now are in.
The disadvantage of geothermal energy
The overall cost of starting a geothermal power plant is quite substantial and this is one hassle we have to face with this alternate source of energy. But many are of the opinion that this initial cost will soon be compensated since operation costs are extremely low and cost of drilling and maintenance of these plants is surely on the decline.
Difficulty in installing this system in areas that are densely populated is another issue faced by geothermal energy. Since this system requires long pipes and wide spaces for the trenches a lot of space is needed which is absent in the densely populated parts.
Conclusively it can be said that the technology for geothermal energy is constantly improving and geothermal plants are becoming readily available. Once the overall costs are reduced the benefits we can derive from geothermal energy multiply for sure making the pros of geothermal energy override the cons.
