Geothermal energy is one of the least exploited renewable energy sources in Spain, despite its enormous potential. While other European countries have firmly committed to this technology, Spain has only just begun to develop its geothermal capabilities. However, the conditions of the Spanish subsoil, especially in regions such as Canary Islands and northern peninsula, make this resource highly viable for power generation, heating and cooling.
In this article we analyze in depth the current situation of geothermal energy in Spain, its development, the opportunities it presents and the challenges it faces. In addition, we will see how this technology can contribute to energy independence and the reduction of CO₂ emissions in the country.
What is geothermal energy?
Geothermal energy It is the process that uses the heat stored inside the Earth to generate electricity or provide heating and cooling for buildings. This heat is stored in underground layers and can be extracted through drilling, which allows it to be used in different applications.
There are three main types of geothermal resources:
- High temperature (over 150 ºC): It is used for the generation of electricity in geothermal power plants.
- Medium and low temperature (between 30 and 150 ºC): Applications in heating, cooling and hot water production.
- Very low temperature (less than 30 ºC): Air conditioning systems using geothermal heat pumps.
Geothermal potential in Spain
Although the use of geothermal energy in Spain is still limited, several studies have shown that the country has enormous potential in this technology. Regions such as Canary Islands, Galicia, Castile and Leon, Andalusia and Catalonia present ideal conditions for their development.
Spain has a variety of geothermal resources, ranging from hot aquifers to areas with volcanic activity in the Canary Islands. However, the main challenge has been the lack of investment and incentives for their development. In this sense, initiatives such as Galicia's commitment to lead production renewable energy are examples of how progress can be made in this area.
Applications of geothermal energy in Spain
In our country, geothermal energy is being used mainly in two areas:
- Electricity generation: Although Spain does not currently have geothermal power plants, the possibility of developing such plants in the future is being explored in the Canary Islands.
- Thermal uses: In the field of air conditioning, geothermal energy is being used in buildings and homes through heat pumps to provide sustainable heating and cooling. This type of system is related to the More efficient heating solutions.
Various projects have shown that geothermal energy can be an alternative efficient and profitable to reduce the consumption of fossil fuels in sectors such as industry, tourism and construction.
In addition, the implementation of geothermal energy can contribute significantly to the GDP growth from renewable energy.
However, in order to carry out these projects, it is essential to have a legal framework that encourages research and development in the geothermal field, as well as better supporting policies.
Taking advantage of the potential of geothermal energy also requires significant investments. Although we are beginning to see progress, we still have a long way to go.
Understanding the benefits of geothermal energy and its applications in Spain is key to its acceptance and expansion. Know the advantages and disadvantages of this energy source can help inform the public and policy makers about its feasibility.
Therefore, effective communication and education about the possibilities of geothermal energy will be essential for its development in Spain.
Benefits of geothermal energy
The use of geothermal energy in Spain has numerous advantages:
- Renewable and clean energy source: It does not produce direct emissions of CO₂ or other pollutants.
- Constant availability: Unlike solar and wind, geothermal energy is not dependent on climatic factors.
- Reduction of energy dependence: Its development would contribute to reducing gas and oil imports.
- Local employment generation: Its implementation would promote the growth of the renewable sector in Spain, which is vital at a time when the sustainable employment it is more necessary than ever.
Challenges for the development of geothermal energy
Despite its potential, geothermal energy in Spain faces certain challenges that have slowed down its development:
- High initial costs: Investment in exploration and drilling is high.
- Lack of incentives and institutional support: More aggressive policies are needed to encourage this technology, something that could be addressed through plans such as those promoted by Brussels.
- Lack of knowledge of the sector: Geothermal energy remains a little-known technology in Spain, which limits its acceptance and development.
Geothermal prospects in Spain
With the push for renewable energy in Europe and the need to reduce dependence on fossil fuels, geothermal energy can play a key role in Spain's energy transition. Pilot projects are currently underway and new infrastructures for its use are expected to be established in the coming years.
The growth of the geothermal sector will not only reduce the environmental impact, but will also generate new employment opportunities and strengthen the country's energy autonomy. A future where geothermal energy is an integral part of our energy matrix is possible if the resources are properly managed. energy goals for 2030.
Spain has great potential to become a benchmark in geothermal energy, but this requires greater investment, support policies and a change of mentality in the way in which energy resources are used.
