Most scientists and experts believe that geothermal energy is one of the most beneficial energy sources in the world. It is not only a renewable source of energy, but it is also present in most places, which makes it outperform the traditional sources in many ways. One of the best examples of using geothermal energy is a nordic country –  Iceland. The country has 100 percent sustainable electricity which uses hydro, wind, and mostly – geothermal energy. So, why are countries around the world increasingly investing in geothermal energy? It is because of the numerous advantages it provides. In this article, you will be able to read about the benefits of this renewable energy. Let’s take a closer look:

1. It is Eco-friendly

When compared to fossil fuels, this type of energy plant does not involve combustion. This means that there is a major reduction in greenhouse gases, as well as emissions that are all harmful to our environment. Geothermal energy will also allow you to save a lot of money of up to 80 percent in savings.

2. It is a Reliable Source of Renewable Energy

Not only does geothermal energy have various advantages over traditional energy sources, but it is also more beneficial then wind, solar, and biomass energy sources. It is a constant source of energy which means that it does not depend on any other factor such as the wind or sun, and it is available 365 days a year. There were various studies conducted on the availability factor of energy sources (that studied how constant and reliable a specific energy source is), and geothermal energy has always been ranked on top. These studies support the fact that geothermal energy is an independent, reliable source of energy.

3. The Geothermal Systems are Quite Efficient

One of the most interesting things about this source of energy is that it uses 25%-50% less electricity than traditional systems for cooling or heating. Also, according to the expert team from, since these systems usually have a flexible design, they can easily be implemented in different situations and they require less space for the equipment to be installed.

4. There is Little to No System Maintenance

Since these systems only have several moving parts located in a facility, the life cycle of a geothermal heat pump system is extremely high. The heat pump pipes have a life span of 25 to 50 years, while the pump can easily least over 20 years.

5. Great for Both Heating and Cooling

In order to generate electricity with geothermal energy, the water temperature needs to be above 150ºC which is 300ºF. However, there is a different way of generating electricity is to use the small temperature difference between the ground source and surface. The earth is more resistant to changes in temperatures than air, hence, the ground can act as a heat source with the implementation of a geothermal heat pump.


As you can see, geothermal energy is not only a stable, reliable source of energy, but it is also environmentally friendly, less expensive, and more efficient.
