Advantages and Disadvantages of Geothermal Energy

In this article I will discuss all the “Advantages and Disadvantages of Geothermal Energy” in detail. Firstly, I will explain what geothermal energy is. How does it work?

The geothermal energy source is a sustainable and renewable source of energy that is largely untapped.

It may be able to provide cooling, heating, and electricity needs of the future as a resource that is environmentally friendly.

Geothermal energy is advantageous in many ways, but there are also some challenges facing its full exploitation.

Geothermal Energy:

Earth’s subsurface releases heat through geothermal energy.

It can also be excavated from the hot molten rock, magma of the Earth, which is beneath the crust of the Earth.

In order to generate electricity from geothermal energy, wells have to be dug about a mile deep into underground reservoirs, which contain streams of hot water that are used to operate turbines connected to electricity generators.

Geothermal power plants come in three varieties: flash power plants, dry steam power plants, and binary power plants.

A major advantage of geothermal energy is its ability to provide long-term energy.

Additionally, it is a renewable energy resource that is locally available, making it superior to many conventional energy sources in several ways.

Advantages and Disadvantages of Geothermal Energy

I will now discuss the advantages and disadvantages of geothermal energy.

As an introduction to geothermal energy, let’s discuss its advantages.

1. Advantages of Geothermal Energy:

I. Environmentally Friendly:

Coal and other fossil fuels are not as environmentally friendly as geothermal energy.

As an added benefit, geothermal plants emit small amounts of carbon dioxide.

Geothermal energy produces very little pollution in comparison to fossil fuels, though it is still less than fossil fuels.

II. Renewable:

In about 5 billion years, our planet will be destroyed by the sun by using geothermal energy.

As the Earth’s hot reservoirs are replenished naturally, the planet has a sustainable and renewable natural energy supply.

III. Huge Potential:

Around the world, energy consumption is at 15 terawatts, which is way more than the total energy that can be tapped from geothermal energy.

 While most geothermal reservoirs currently cannot be used by humans, there is a possibility that the number of exploitable geothermal resources will increase with ongoing research and development in this industry.

The world’s geothermal energy plants are estimated to be capable of producing between 0.0035 terawatts and 2 terawatts of power.

IV. Sustainable / Stable:

Comparatively to other renewable energies such as wind and solar, geothermal energy offers a sustainable alternative.

As opposed to solar or wind power, these resources are always available to tap into.

V. Heating and Cooling:

Water temperatures over 150°C are needed for proper geothermal energy production to drive turbines. Meanwhile, the ground source is going to be compared to the surface source based on the difference of temperature.

During the changing seasons, the ground is much more resistant than air to heat changes. This means that a 2-meter-under-ground geothermal heat pump will act as a source or sink of heat.

VI. Reliable:

Since geothermal energy does not fluctuate like various other energy sources such as wind or solar, it can easily be calculated.

Thus, we can predict the output of a geothermal system with a high degree of accuracy.

VII. No Fuel Needed:

Unlike fossil fuels, which are finite and must be mined or extracted from the earth, geothermal energy is a resource that naturally occurs and does not require fuel.

VIII. Rapid Evolution:

At the moment, geothermal energy sources are undergoing extensive exploration, implying that new technologies are being developed to improve the energy process.

 This sector of the industry has an enormous number of projects in development.

Geothermal energy’s cons are going to be mitigated by this exponential growth.

2. Disadvantages of Geothermal Energy

We will now discuss the disadvantages of geothermal energy.

I. Location Restricted:

One of the greatest disadvantages of geothermal energy is its location-specificity.

 As it is not possible to exploit geothermal energy in some areas, geothermal plants cannot be set up there.

Those living in areas with easy access to geothermal energy, such as Iceland, would not have a problem with this.

II. Environmental Side Effects:

While geothermal energy does not often release greenhouse gases into the atmosphere, the minerals under the Earth’s surface can release some of these gases into the atmosphere.

There is an increase in these gases near geothermal plants, despite natural releases of these gases into the atmosphere. The gas emissions associated with solar are still much lower than those associated with fossil fuels.

III. Earthquakes:

Earthquakes can also be triggered by geothermal energy. Due to the disruption of the soil structure caused by digging, this is the case.

Enhanced geothermal plants have exacerbated the issue because they force water into Earth’s crust in an effort to open fissures that can then be exploited for energy.

In contrast, since most geothermal power plants are far from the centers of population, their impacts are relatively minor.

IV. High Costs:

One megawatt of geothermal energy costs between $2-5 million, making it a highly expensive resource to tap into.

Although the upfront costs are high, they can be recouped over time as part of a long-term investment.

V. Sustainability:

Geothermal energy is sustainable only if fluid is pumped back into underground reservoirs faster than it was depleted.

As a result, geothermal energy must be properly managed in order to remain sustainable.

Geothermal energy advantages must be evaluated and weighed against any disadvantages in order to mitigate any potential issues.

Conclusion of advantages and disadvantages of geothermal energy:

One of the cleanest and most renewable energy sources on the planet is geothermal energy.

There are fewer greenhouse gases and toxic chemical products produced, so it is a more efficient way to produce power.

There is great potential in geothermal energy, and its applications are expected to grow in the coming decades.

The drawbacks of geothermal energy include its limited use in small areas. However, this may be resolved by building smaller geothermal plants close to each other in close proximity to the same source of geothermal energy.

In spite of the fact that geothermal energy systems are typically expensive to place, they can technically be placed anywhere in the world, making them an attractive renewable energy source.

Due to its weather independence, geothermal heating and cooling can provide power 24 hours a day, making it an extremely reliable renewable energy source.

In the future, geothermal energy will likely become an even more popular topic to study and incorporate into environmental courses as geothermal energy grows in popularity.
