Geothermal energy is the type of energy that belongs to thermal energy. The energy of heat and other distinct physical concepts is known as thermal energy. Thermal energy is also known as the energy that determines the temperature of matter.

Heat energy gets derived from the surface of the Earth. It gets stored within the Earth. There are lots of advantages and disadvantages of geothermal energy. Almost 26 countries use geothermal electricity generation. On the other hand, 70 countries use geothermal heating. There are various examples of geothermal energy like hot springs, lava, fumaroles. However, geothermal power is widely in use in most businesses and homes.

Let’s get dwell on some of the pros and cons of geothermal energy.

Advantages And Disadvantages Of Geothermal Energy

Advantages Of Geothermal Energy

Here we are going to discuss some advantages of geothermal energy. Being a natural and renewable source of energy it is very reliable. Geothermal energy doesn’t require fuel to extract it from the core as well as emit greenhouse gases.

1) Its a renewable source of energy

Types of geothermal energy like Hot springs, fumaroles get produced from the surface of the Earth. They get replenished naturally. It makes energy sustainable and renewable. Also, the amount of heat-generating from the Earth’s surface is enormous. Heat energy gets produced frequently from the Earth’s core. Hence, there is less chance of geothermal energy going on shortage in the future.

2) Environmental friendly

Geothermal energy is friendlier to the environment than other fossil fuels like coal, natural gas, petroleum, etc. The carbon production or footprint generated through geothermal energy is minimal. It doesn’t cause harm to the environment. When the heat gets pumped up to the Earth’s surface, it has zero defeatist effects on the environment.

Geothermal energy is convenient to use as its production causes less noise to the environment. The energy keeps your home comfortable as the entire system is underground. It is the best source of heating and cooling effect that you will get into your house.

3) It is one of the stable sources of energy

Since the energy generated from the Earth’s crust is in abundance, it is less likely to have insufficiency. Also, the geothermal plant produces emissions that don’t require constant backup. Therefore, according to the sources, it has minimal effect on the air quality. Unlike solar and wind energy, geothermal energies don’t need to get conserved and trapped continuously.

4) Geothermal energy helps to enhance employment

The establishment of geothermal energy projects in rural areas has broadened employment opportunities. It has helped to increase the creation of new jobs. According to the sources, the initiation of the plan in 2012, based on the New Power Complex in Imperial Valley, United States, has helped about 323 workers to get employment. More than 57 jobs got created in the field of maintenance, engineering, administration, and operations.

5) It reduces your utility bills

Installing a geothermal energy system allows you to have higher comfort at your house at a low cost. However, the initial installation of the system may be costly but, if you look at the bigger picture, it has lots of advantages. When the geothermal energy system gets fully installed and operated, you will see the utility bills get reduced by 50%.

Most of the businesses take the loan for system installation, and later the savings from utility bills can be enough for loan repayment. Geothermal energy requires a minimal amount of electricity for the generation of heat. It only generated four units of energy per unit of electricity required to drive the system.

6) No fuel required

During the production or generation of geothermal energy, it requires no fuel. It doesn’t require mining and transportation-related processes. It also signifies that it doesn’t emit gas and fumes that pollute the environment.

7) Innovation in Technology

Since people have been talking about green energy these days, geothermal energy has taken all the eyes currently. People are exploring more geothermal energy. New innovative technologies are getting introduced that will help in the efficient generation of geothermal energy.

8) Free production of hot water

Hot water produced as a form of geothermal energy is in use by everyone near the place. It also used to consider as bathing water since Paleolithic times and from ancient Roman times. However, these days’ people use hot springs for the production of electricity. According to the data of 2019, there is 13900 Megawatts production of geothermal power.

Disadvantages Of Geothermal Energy

As we know good and bad co-exist with each other, we are going to have a look at some disadvantages of geothermal energy. It has some criteria before the production or construction of the plant. The natural source of nature will depend on nature, we are not able to extract geothermal energy if the earth’s temperature cools down.

1) It can get built at specific sites only

For a giant geothermal plant minimum of 100 degrees, Celsius temperature is necessary. The temperature of reservoirs should be similar to that. It is easier to say but, geothermal plants aren’t suitable everywhere. These reservoirs are usually found in specific locations only like, near hot spots or tectonic place boundaries. Therefore, the majority of U.S geothermal power plants are in California.

2) Chances of earthquakes

While constructing a geothermal power plant needs a lot of deep drilling within its surface, which creates hot steams and water trapped in rock formations. Doing so will cause instability underground that can lead to earthquakes. It also causes slow land subsidence shortly as the reservoir gets depleted.

3) Depletion of the sources

There is a high possibility of the depletion of geothermal sources in the future. As we know, it is one of the types of renewable and stable sources of energy. There is a higher probability of sources like hot springs getting cooled down, impossibility to harvest geothermal energy.

Environmentalists are working on a non-depletable option for the generation of geothermal energy. One possible option is to source geothermal energy directly from the magma. There are still lots of improvements required to form this technology and implement it properly. The presence of magma will be for many years in the future. It has become one of the crucial alternatives to conserve and produce geothermal energy.

4) Greenhouse emission

After knowing the fact about geothermal energy is eco-friendly. We also need to consider about possibilities of the emission of greenhouse gases during the production of geothermal energy.

The extraction from the grounds can release a small number of greenhouse gases like carbon dioxide, hydrogen sulfide, ammonia, and methane. However, the amount of greenhouse gases released while producing geothermal energy is far lesser than fossil fuels.

Hence, there are some advantages and disadvantages regarding geothermal energy. It is the only renewable resource that can be of great use for the production of large amounts of heat. But during the process of production or extraction, there might be some complications and emission of greenhouse gases that might affect the environment as well as the earth’s core during deep underground drilling.
