We have always needed useful energy resources that could make our daily lives more comfortable. With technology getting advanced everyday machines are being produced that could give us a hand in our daily chores. To make these work machines work, we need energy sources to provide them the power to operate. We have been using non- renewable energy sources such as fossil fuels to generate electricity, move automobiles, etc. Unfortunately, we failed to realize that these sources wouldn’t last for long, and we would soon require more reliable sources.

With advance research and studies, we came up with renewable energy sources that could work in the same way as fossil fuels work and would be safer to use. They wouldn’t harm the environment much and will in abundance for us to use. Hydropower, solar power, wind energy, and geothermal energy are some sources that work great for our needs.

What is geothermal energy and is it renewable?

Geothermal energy is formed by the molten and heated interiors of the earth, which are positioned at the planet’s core. The molten materials have a very high temperature and can provide a large amount of energy for various purposes.

Like any other renewable source of energy, geothermal energy is extracted from the earth itself through machinery. Geothermal energy is present in the core of the earth in the form of heat and is extracted by us to work as a fuel for various purposes. This heat present inside the earth is not produced by the Sun. It is a renewable source of energy as its almost unlimited amount of heat present in the earth’s core. We would be able to utilize a lot of this source for a long time as the heat present inside the planet would last for a long time to come.

What is the source of geothermal energy and what type of energy is geothermal energy?

Geothermal energy, as has been mentioned above, comes from the inside of the earth. This energy is produced in the earth’s core due to the molten interiors. The heat generated by these molten rocks and fluids provides the needed energy which can be harnessed to pump electricity, etc. The earth’s interior consists of radioactive materials which sometimes go through fission or radioactive decay and create a healing effect on the surroundings. This leads to the creation of some hot spots that give rise to geothermal energy.

Geothermal energy is present in an abundant amount in the earth’s core. Due to this fact, it is a renewable source of energy that can be used in large amounts. This makes sure that it has a bright future and would be used for various purposes for many generations to come.

What is geothermal energy used for?

There are various vital uses of geothermal energy that are not very popular, but one should know about it.

Generation of electricity:

For this process to work, massive turbines and generators are used that connect to pumps and bring out the energy present inside the earth. The heat energy from down below is used to convert water into steam. The purpose of the steam is to move turbines, which ultimately produce high amounts of electricity. This process is environmentally friendly and is not very difficult to execute.

Heat cold buildings:

During extreme winter months, to heat the inner temperature of a house or a building, instead of using a central heating system, geothermal energy is used. Pipelines are connected to the bigger pipelines that are ultimately connected to the hot spots that are made inside the earth’s crust. Due to this, the heat gets transferred to the buildings and brings up the temperature ultimately.

The energy inside the molten earth can be used to power generators and pumps that work on a large scale. The molten core of the planet is a storage of energy that can be used to heat cool buildings if need be.

Daily chores:

Geothermal energy acts as the best replacement for geysers and electrical water heaters. They can be used to heat water at little cost in the long run. This water can be used for daily chores such as bathing, washing, cooking, etc.

What is the cost of geothermal energy?

Considering the amount of money we spend on non-renewable energy sources such as fossil fuels, generating geothermal power doesn’t cost a lot, especially in the long run. An entire power plant has to be built that would have all the required machinery to generate geothermal power. An average power plant costs about $0.01-$0.03 every KWH. This cost can vary according to the type of geysers and the time when it is being produced.

To estimate costs in such cases depends on the time when the energy is generated. For instance, when geothermal energy is in demand, like in winter months, the generation could be costly. In the season of low demand, the production of geothermal energy could be more profitable.

What is good about geothermal energy?

There are various advantages of using geothermal energy instead of going for fossil fuels.

Abundance:

To start with, this type of energy is present in abundance in the earth’s core and is a renewable form of energy. It can be produced anywhere on earth. You just have to build a power plant over any hotspots inside the earth’s crust, and you would be able to extract a lot of energy under a short while.

Promised profits:

With fossil fuels depleting in quantity, people have no option but to switch to renewable energy sources such as geothermal energy. As soon as more methods of generating and using this energy will come up, its requirement would increase and would bring you a lot of profit for sure.

Various uses:

Geothermal energy has several purposes. From industrial applications like electricity generation to heating water for household uses, geothermal energy comes as a handy source of energy.

What is a disadvantage of geothermal energy?

Like any other energy source, renewable or non-renewable, geothermal energy has various geothermal energy pros and cons.

Harmful emissions:

When geothermal energy is generated, the emissions that are produced during the production get mixed with the atmosphere by traveling to the surface and then to the atmosphere. This impacts the environment and sometimes creates problems like being hard to breathe.
