Did you know that the habitation of Paleo-Indians near hot springs more than 10,000 years ago was the earliest human use of geothermal resources in North America? Warmth and cleanliness were provided by the springs, while healing was provided by their minerals. Although geothermal energy was used mostly for health back at the time, now it serves a range of purposes.

In this article, we will talk about what geothermal energy is, what advantages and disadvantages it has, and its importance.
Geothermal energy can be defined as thermal energy occurring from the energy captured throughout the Earth's formation and from the radioactive decay of materials about 5 billion years ago. However, since the rate of energy emerging from the Sun is 5000 times faster than the rate of heat flow through Earth's crust, Earth's surface temperature is determined by energy from the Sun rather than heat flowing from its core.
Geothermal energy is considered to be a renewable resource since its source is the nearly limitless quantity of heat generated by the Earth's core. Also, it is a sustainable energy source because even if geothermal areas rely on a hot water reservoir, the volume of water extracted can be reinjected.
The three main geologic formations: hydrothermal vents, geopressured, hot and dry rock, and magma enable geothermal energy extraction. Locations in which geothermal energy is available are distributed in areas with geologic instability that frequently undergo active volcanoes and tectonic movements.
Geothermal energy sources have many benefits which makes them a popular energy source where it is available. Geothermal energy is renewable, meaning that it is naturally replenishable on a human time scale. Geothermal energy is sustainable, meaning that it meets the needs of current generations of humans without impinging upon the ability of future generations to meet their needs. Geothermal energy also doesn't cause a huge amount of pollution or produce much carbon in its production, making it an environmentally friendly energy source.
Some of the uses of geothermal energy are listed below:

Where does geothermal energy originate?
From the energy captured throughout the Earth's formation and from the radioactive decay of materials about 5 billion years ago.
Why is geothermal energy considered a renewable energy resource?
Because its source is the nearly limitless quantity of heat generated by the Earth's core.
Which geologic formations enable geothermal energy extraction?
Hydrothermal phenomena, geopressured, hot and dry rock, and magma.
