Advantages and disadvantages of geothermal energy
The Earth is composed of many layers; the closer you get to the core, the hotter it’ll be, since it can reach the astonishing temperature of 6000° C (about 10800° F). In other words, planet Earth is full of heat, and this is heat is called Geothermal Energy. This kind of energy serves nowadays for many purposes, and it is an environment friendly alternative to fossil fuel. It is used for a wide variety of things, from de-icing roads to industrial processes, but how does geothermal energy work?
It depends. Geothermal energy can be obtained both through geothermal power plants, or geothermal heat pumps: geothermal power plants take the energy obtained from underground heat (that’s directed through pipes in the form of hot steam) and convert it to electricity with the help of turbines, while geothermal heat pumps extracts that heat that’s absorbed by pipes buried underground to then redirect it to a building, bringing the heat indoors.
To consider the many geothermal energy pros and cons residential as well as industrial we need to factor ROI ( return on investments ) to see the costs associated.
Then, it can be given many usages, but its utilization presents, as many other technologies, advantages and disadvantages.
Advantages of geothermal energy :
Disadvantages of geothermal energy:
- It is a renewable source of energy.
- It doesn’t cause significant pollution; therefore, it is environment friendly.
- It could meet the base load energy demand
- It is available everywhere
- It doesn’t depend on weather conditions, unlike other renewable sources of energy
- Maintenance costs of geothermal energy power plants are rather low, in comparison to others.
- Also, it occupies very little space on land, since they can be built partially underground, which makes it an even more environment friendly option.
Pros & cons are looked at here. This article is looking at commercial plants for distribution to the homes.
- Geothermal power plants installation costs are very high
- There’s no guarantee the amount of energy produced will cover the expenses of capital expenditure and operation costs.
- Very few places have the potential for geothermal installations.
- Geothermal power is only sustainable if the reservoirs are properly managed.
