Weakness Of Geothermal Electricity (All You Need To Know)

Here is all information about the Weakness Of Geothermal Electricity. One of the most favorable energy sources currently is geothermal energy. It is not only a renewable energy source but also widespread and outperforms even specific conventional sources in many ways.

The UK is also considering building the most extended power cable between the UK and Iceland, providing 1.6 million British homes without geothermal heat pumps with more renewable energy. If all necessary funding is raised, the first geothermal power plant for commercial use will also be built in Cornwall, UK.

That shouldn’t be shocking, considering that some nations greatly benefit from geothermal energy. The best-known example is Iceland, which uses wind, hydroelectric, and geothermal energy to generate electricity.

But if you want to save your energy costs, you don’t need a backyard the size of a football field. More and more homes worldwide are purchasing ground-source heat pumps and heating systems to reduce their expenditures.

Weakness Of Geothermal Electricity

The fact that geothermal energy is location-specific is its biggest drawback. Because geothermal plants must be constructed where energy is available, some regions cannot utilize this resource.

What Are The Advantages Of Using Geothermal?

Environmentally Friendly

Compared to conventional fuels like coal and other fossil fuels, geothermal energy is more environmentally benign. Moreover, a geothermal power plant has a small carbon footprint. While geothermal energy does produce some pollution, it is much less than that produced by fossil fuels.


Geothermal energy is a renewable resource that will be available until the sun destroys the Earth in about 5 billion years. Because the Earth’s heated reserves are refilled naturally, it is both renewable and sustainable.

Huge Potential

Over 15 terawatts of energy are currently consumed globally, a small fraction of the total energy that may be obtained from geothermal sources. Although most reservoirs cannot now be used, there is hope that as industrial research and development continue, the number of geothermal resources that can be used will rise. Geothermal power facilities can produce between 0.0035 and 2 terawatts of energy.

Sustainable / Stable

Compared to other forms of renewable energy like solar and wind, geothermal energy offers a consistent stream of energy. This is so that the resource is always available, unlike wind or solar energy.

Heating And Cooling

Water must be over 150°C for turbines to be driven by geothermal energy effectively. Alternately, the differential in temperature between a ground source and the surface might be utilized. A geothermal heat pump can operate as a heat sink/source only two meters below the surface since the ground is more resistant to seasonal heat variations than the air.


As it does not fluctuate as much as energy from other sources, like solar and wind, it is simple to compute the amount of energy produced by this resource. This implies we can predict highly accurately a geothermal plant’s power output.

No Fuel Required

There is no requirement for fuel because geothermal energy is a naturally occurring resource, unlike fossil fuels, which are limited resources that must be mined or otherwise extracted from the Earth.

Rapid Evolution

Geothermal energy is currently the subject of extensive research, meaning new technologies are being developed to enhance the energy process. Many initiatives are being undertaken to advance and expand this sector of the economy. This rapid evolution will mitigate many of the existing drawbacks of geothermal energy.

What Are The Disadvantages Of Geothermal Energy?

The coin always has two sides, therefore let’s look at the disadvantages of geothermal energy:

What Are The Disadvantages Of Geothermal Energy

Environmental Concerns About Greenhouse Emissions

Geothermal energy, unfortunately, also raises a few minor environmental issues, despite its image as an environmentally sound alternative energy source. Greenhouse gases, including carbon dioxide, methane, and ammonia, are produced when geothermal energy is taken from the ground. However, the amount of gas released is far less than it would be with fossil fuels.

Possibility Of Depletion Of Geothermal Sources

Also, although geothermal energy is seen as a sustainable and renewable energy source, some regions would likely cool off, making it impossible to continue harvesting geothermal energy in the future.

The only non-depletable method is directly obtaining geothermal energy from magma, although this technology is currently being developed. The fact that magma will exist for billions of years is the primary factor making this choice worthwhile financially.

High Investment Costs For Geothermal Systems

The hefty initial cost for individual households is another drawback. The cost increases significantly because one must dig into their home and install a complicated system. Yet, the return on such an investment is quite promising, with the ability to recoup the initial investment in 2 to 10 years.

Land Requirements For Geothermal System To Be Installed

In the case of geothermal systems, it is necessary to have a plot of land close to the house in order to build one. Due to this, installing geothermal systems for homes in large cities is only possible if a vertical ground source heat pump is employed.

Is Geothermal Energy Expensive?

Geothermal energy’s “high cost” is seen as one of its drawbacks and should not be reduced. In general, the majority of geothermal resources cannot be utilized profitably, at least not with present technology, subsidies, and energy prices. The cost of geothermal energy varies depending on the built-loop device.

Commercial geothermal technology investments are pricey. Typically, the total installation expenses for a geothermal power plant with a 1 Megawatt (MW) capacity would be between 2.5 and 5 million dollars. The expense is greatly increased by reservoir drilling and exploration.

Geothermal power facilities are also expensive to build and occasionally difficult to locate. For structures or homes that employ geothermal heating and cooling, there are significant upfront investments that do not quickly pay for themselves.

For houses and commercial structures, geothermal cooling, and heating systems are extremely pricey. These devices can be thought of as long-term investments because they are expected to save you money for many years.

Land heat pumps typically have an installed cost of $15,000–$40,000 and a 10–20 year payback period. Costs may become unaffordable if geothermal energy is transported over great distances.
