1 Major Reason Why Geothermal Energy Power Plants Are Not Replacing Renewables

geothermal energy plant

Geothermal energy power plants generate renewable energy and geothermal energy is a renewable form of power that does not depend on the weather. It’s a practical alternative to fossil fuels and nuclear energy since it can generate continual power no matter what the weather is like as long as there is a constant supply of water. One major reason why geothermal has not replaced other forms of renewable energy could be the cost of construction.

What are geothermal energy power plants?

Let’s cure your curiosity about what geothermal energy power plants are! These innovative plants generate electricity by harnessing the Earth’s natural heat from the mantle. The process involves using an underground water reservoir to heat water, which in turn generates electricity. Although geothermal energy plants have been around for over 50 years, they have not replaced renewable energy sources like solar and wind. However, they offer a stable and consistent energy source, making them an excellent backup for renewable energy systems. Plus, unlike fossil fuels they have an eco-friendly benefit as they do not pollute the environment with chemical emissions.

One of the most significant advantages of geothermal power plants is their ability to provide uninterrupted energy sources to economies worldwide. For instance, countries like Iceland and Norway rely on these plants to provide a non-stop stream of power. With their continuous and reliable energy source, geothermal energy power plants are proving to be an increasingly attractive option for countries looking to reduce their dependence on fossil fuels.

What are the current challenges with geothermal power?

One major reason why geothermal energy power plants have not been replacing renewable energies like solar, wind, and hydropower is that locations, where the Earth’s crust is shallow, are rare. Geothermal energy is generated by the heat from the Earth’s mantle, which is right below the Earth’s crust. To reach close to the mantle, you must first dig through the crust. Since the crust is several kilometers thick in most locations, it is often difficult to find a site for a plant.  Most of the time, an ideal site for a Geothermal powerplant would be in areas with high volcanic activity.

So, it may be time to ask the question; how much is the efficiency of geothermal plants? Geothermal energy is expensive to produce and has low-efficiency rates. It can be expensive to maintain a plant once built. A steady supply of water is required to produce steam, which turns a turbine, and water is generally scarce in geographically ideal sites for geothermal energy power plants. Transporting water to power plants can be expensive and troublesome, which will increase the cost per kilowatt of energy produced.

Do geothermal plants pollute?

To answer the question “Do geothermal plants pollute”, let’s look at how geothermal power is obtained. geothermal energy is derived from the heat of the Earth’s interior. The heat is used to generate electricity and because geothermal energy is clean, renewable and produce no emissions, it has been seen as a potential replacement for traditional forms of power generation. However, because geothermal plants require large amounts of land and are very expensive to build, they have not yet become a widespread source of electricity.

There are several reasons why geothermal energy plants have not replaced renewables in the market. At first, geothermal energy requires a lot of lands, which is in short supply. Second, geothermal plants are very expensive to build; and third, there is no market for geothermal power yet. Geothermal energy is clean, renewable, and has no emissions, but it’s very expensive to build and use.

Can geothermal energy replace other renewable resources?

Geothermal energy power plants have the potential to generate renewable electricity but so far they haven’t been able to fully replace other methods of generating renewable resources.
Here you go with some of the reasons why it isn’t a renewable resource yet

Geothermal energy power plants are not always located near major sources of renewable energy. For example, geothermal power stations in the US are typically located in deserts or high altitude areas where wind and solar resources are scarce. This limits the potential number of geothermal plants that can be built and the amount of renewable energy they can produce.

Geothermal energy is not always available at a reasonable price. Technologies that convert geothermal energy into usable electricity have become more affordable in recent years, but prices remain high compared to other forms of renewable energy. This means that geothermal power stations may still not be cost-effective for large scale projects.

Geothermal energy power plants require a lot of maintenance and have a low capacity to generate electricity over long periods of time. This means that they may only be able to provide small amounts of renewable electricity relative to other forms of renewables such as solar and wind

The widespread availability of geothermal power sources depends on their cost. Because geothermal plants require large amounts of land and are very expensive to build, they have not yet become a widespread source of electricity in the market. However, as the price of geothermal technology continues to drop together with the arrival of new technologies into the market, and more funding is available to research new ways of extracting and using the resource, there will be an increasing demand for geothermal energy. With the right technology and policy support, energy from this new generation of geothermal power plants can become commercially viable.


We are all aware that renewable sources of energy are quickly becoming the go-to choice for energy production. Geothermal energy power plants have a lot of potentials but one major reason why they haven’t taken hold as an alternative to traditional sources is that they are not as cheap.

The other reason is that they are just difficult to locate since the power plant needs to be close to a source of geothermal activity. However, this doesn’t downplay any of the serious advantages geothermal energy power plants offer.

Solar and wind turbines can be stopped by bad weather conditions or other reasons, whereas geothermal energy power plants work even when the sun isn’t shining or the wind isn’t blowing. This means that geothermal energy can provide stable power even in times of emergency as we have seen in many countries that have already adopted this method of power production.
