No man can ever create the abundant bounty of energy supplies that the universe gives us. While the main external source of energy for our planet is the Sun, the internal sources are the rotational energy of the Earth and the Geothermal Energy from the radioactive isotopes.
What is Geothermal Energy?
Geothermal Energy has its name because it is obtained from the Geo or the Earth. It is produced from the hot rocks that exist at Earth’s core where the temperature is close to 7200 degrees Fahrenheit. It is produced due to the fission of radioactive materials in the Earth’s core. There are obviously, both advantages and disadvantages of Geothermal Energy, but it is yet to be decided whether its pros are more or its cons.
What are Advantages and Disadvantages Of Geothermal Energy
What are the advantages of Geothermal Energy?
1. Friends with the Environment
There are certain polluting aspects to Geothermal Energy but the carbon footprint of a geothermal power plant is minimal, which amounts to one eighth of the carbon di-oxide emissions of a coal power plant.
2. Renewable And Stable
Geothermal Energy is a renewable source of energy as its reservoirs are naturally replenished which may last billions of years. It is also a stable source of energy because its power outputs can be accurately predicted and are not subject to fluctuations like the solar energy or wind energy.
3. Abundance And Accessibility
The sites of Geothermal Energy are found in abundance across the Earth’s surface and are mostly easily accessible too.
Geothermal Energy has massive energy production potential. The upper estimates show a potential of two terawatts (TW).
It requires no footprint on land because the mining sources of a geothermal power plant are underground and even small households can benefit from the heating and cooling of a geothermal plant.
What are the disadvantages of Geothermal Energy?
1. Greenhouse Gases Emissions
There is a potential of emissions of Sulphur dioxide and silica as the results of Geothermal Energy production. Also, the reservoirs of a Geothermal Power plant contain heavy metals like mercury, arsenic, boron etc.
2. Land Stability Affected
The production of Geothermal Energy can trigger Earthquakes. In January 1997 in Switzerland, there was an earthquake due to this of 3.4 magnitudes on the Richter Scale.
There is a high up-front cost for electricity and heating and cooling systems, plus distribution costs. The estimate for 1MW Geothermal Power plant is 2-7 million dollars.
4. Location Specific
The locations for geothermal plants are hard to come by and mostly situated far from population centers.
5. Not a 100% Sustainable
Geothermal Energy is only renewable if the reservoirs are properly managed.
Discussing the advantages and disadvantages of Geothermal Energy, the bottom line is that it is eco-friendly, sustainable and reliable but the heavy costs upfront stops us from reaching the full potential of Geothermal Energy.
