What Is Geothermal Energy?
Geo means ‘earth’ and thermal means ‘heat’. Geothermal energy is thermal energy that is generated and stored on earth. Thermal energy determines the temperature of matter. Geothermal energy is created from the formation of the planet and after the radioactive decay of matter.
Geothermal energy is sustainable, cost-effective, and environment friendly, but it has been isolated near areas of tectonic plates.
Geothermal pipes are buried 4 feet deep in the earth. The pipe pumps a liquid to absorb the heat and bring it indoors. The heat exchanger carries heat from the liquid and uses it to warm the house.
Moreover, this geothermal energy can be used to cool our houses in the summers as well. It works reverse of the heating system and makes our home cool in summers.
There are many pros and cons of using geothermal energy, swipe up to know about them!

Pros of Geothermal Energy
- Geothermal energy is renewable
- Environment-friendly energy
- It requires no fuel
- A good option for homeowners
- An evolving technology
1. Geothermal Energy Is Renewable
As long as the earth is in existence, there will be a continuous source of energy to harness. It makes geothermal a renewable energy with solar and wind. It will remain in existence since the sun swallows us in the upcoming 5 billion years.
Hot reservoirs extract the geothermal energy from the earth naturally. In this way, geothermal energy is not only sustainable but renewable as well.
2. Environment-friendly Energy
Geothermal energy is a good source of green energy. It means that the effective rate of it on the environment is minimal. Its production does not create harmful substances or pollution.
Their carbon footprints are tiny and less as compare to fossil fuel productions. For the earth’s long term energy solution, geothermal energy’s advancement will be sound a candidate for global warming.
3. It Requires No Fuel
Whenever we heard of power plants, the first thing that clicks our minds is a huge amount of fuel. Just like solar energy and wind energy, geothermal energy is prepared through natural processes.
It is not produced, but experts harness it and convert it to electricity. The worries of mining also fade away, which causes heavy pollution in the environment.
4. A Good Option for Homeowners
As the change in climate occurred, there was an increase in demand for the geothermal heater and cooler for homes. As geothermal energy is renewable, it proves to be the topmost priority for many homeowners.
It seems an expensive step when you go for it, but in a year saves on cooling and heating costs. We pay heavy bills of gas and electricity, and that too fluctuates with the season. In this case, geothermal energy is undoubtedly a wise choice.

5. An Evolving Technology
As the advancement in technology, geothermal energy is in the frontline for exploration. New technologies improve the production process, which makes it the first choice for many people. It is predicted that as the years pass by, the demand will be high for geothermal energy in houses and other places.
Cons of Geothermal Energy
It is essential to keep in mind that technological advancements are never 100% in our favour. They also create challenges that are stated below.
- Side effects for the environment
- Cause of earthquakes
- Sustainability issues
- High investment cost
- The requirement of land for the geothermal installation system
1. Side Effects for the Environment
The production of geothermal energy does not release greenhouse gases, but many issues underneath the earth are ignored. During the digging of earth, some gases are released, which becomes part of the atmosphere.
This happens without the interference of humans. Somehow this issue is hit huge, but still, it is considered to be a con for our surroundings and environment.
2. Cause of Earthquakes
You might be surprised by reading this, but yes, geothermal energy has been notorious for earthquakes. Whenever workers are digging the earth, it is the high chance that earth structure may be altered, resulting in earthquakes.
This activity shifts the tectonic plates, and it causes earthquakes. However, they are not too dangerous, but natural disasters usually come with life-threatening incidents.
3. Sustainability Issues
Geothermal energy is produced by taking extremely hot water from the reservoir of earth. These reservoirs are reloaded when it goes way down due to rainwater. If we use the reservoir too fast, then it will stop the supply. It means geothermal is to be managed effectively; otherwise, it will show sustainability issues.
4. High Investment Cost
It seems friendly when you start using the geothermal energy system, but it is to be kept in mind that it requires high investment cost. Building a commercial power plant is itself pricey; on the other hand, drilling requires heavy machinery, which is a hefty price tag.
The production of geothermal energy is struggling to compete with advanced production, a method that is the other reason behind high investment cost.
5. The Requirement of Land for the Geothermal Installation System
The most significant disadvantage of geothermal is the specific requirement of land. One cannot merely choose by himself where to dig in, but it requires a particular area on earth.
There are a few zones or places on earth where geothermal power plants can be settled down. These are far away from towns and cities which can never be a good option for mass production.
Geothermal energy is, no doubt an excellent source for making life more comfortable. It reliable, eco-friendly, and has a strong impact. It has always been very clean and green. But as it has been a good option for house-owners, there are several disadvantages as well.
High investment is no doubt an issue, but with that, one must know that these advancements are the part of life and we cannot survive without these great inventions and methods such as geothermal energy.
