How does geothermal water work?
You pump cold water through one, the Earth heats it and you draw hot water through the other end. Operators drilling a geothermal well cover it with a steel tube using the same process and technology used to build an oil well. A section of bare rock is left open at the bottom of the well.
What is the problem with bare rock?
Sometimes these small fractures cause small earthquakes. The problem is when earthquakes get too big.
What are the disadvantages of subsoil?
The main disadvantage, in many cases, is that in the cities the subsoil belongs to the city council and is occupied by other services such as sewage, gas and electricity pipes, etc. Only local exploitation. It cannot be transported as a primary source of heat, it must be consumed in the same place where it comes from.
How to take advantage of the internal energy of rocks?
One of the most used techniques to take advantage of the internal energy of the rocks is constructing wells of about 150 meters through which a fluid circulates. The fluid drops at a low temperature, at the bottom it is heated by a thermodynamic process and rises with the thermal energy acquired to the surface.
What are the disadvantages of geothermal energy?
Another disadvantage associated with the production of geothermal energy is the cost of setting it up. There is a high cost of distribution associated with it as well. This cost becomes high since the site for geothermal energy is quite far away from the main population.

1. Environmental Concerns: Emissions of Greenhouse Gases. There are many advantages of geothermal energy that are widely known around the world. However, not many people are aware of the disadvantages that include environmental concerns as well.
Why is geothermal energy extracted from Earth?
It is entirely known that geothermal energy is extracted from Earth because the Earth’s interior is sweltering. There is a concern that such locations, which are the source of geothermal energy, might cool down in the future. Thus, if this happens, there would be no source of geothermal energy in the future.
How long does it take for geothermal energy to return?
It is an excellent source of power, and the return of investment is possible within ten years. Thus, when discussing the pros and cons of geothermal energy, it is important to consider both factors.

What are the problems with geothermal energy?
A common issue that we have seen in areas that utilize geothermal energy is surface instability.
Why is geothermal energy so expensive?
As mentioned above, geothermal energy is expensive, which is not only due to the initial costs of establishing a plant for harnessing it, but also the cost of infrastructure to support the potential earthquakes that it will cause.
How long has geothermal energy been around?
The use of geothermal energy has been implemented by humans for hundreds of years. We began to learn how to harness and control this renewable energy source during the 1800s when we realized that we could use the steam that naturally came out of the surfaces of the Earth to create energy. Whereas the traditional use of geothermal energy has actually been utilized by humans for thousands of years. The historic use of geothermal energy can most commonly be seen used in hot pools around the globe.
Why is geothermal energy dependent on location?
The reason that geothermal energy is so dependent on location is that it can only be harnessed in regions that have high amounts of geothermal activity, which can only be found in areas where tectonic plates meet . In addition, geothermal energy does not only require that the area has heat beneath the surface but also liquid heat that is capable of being harnessed.
Why do geothermal plants have to be cut off?
This can create a lot of stress for everyday citizens in relation to safety concerns. When these sorts of incidents occur, the operators of the geothermal power plant need to dial back their energy consumption or cut it off completely, which can create a lack of reliability for meeting energy needs.
How much does it cost to install geothermal energy?
It is estimated that it costs up to $4 million to install just a single drill for geothermal harvesting. This initial cost can be intimidating and unrealistic for countries that are highly dependent on fossil fuels as their primary energy source. Most nations that can barely afford to make this transition are faced with the challenge of choosing the health of the environment over the practicality of their current energy platform, which stabilizes their economy.
What are the negative effects of geothermal energy?
Negative effects of energy resources are mostly defined in the way their use affects the environment i.e. does it pollute or not?
How practical is geothermal energy?
It’s versatility makes it a practical option for large and small scale use. Although the efficiencies claimed are very high, the fact is that the thermal efficiency of a geothemal power plant is quite low at 17% to 20%.
How does geothermal energy work?
