The move toward a cleaner, more sustainable energy model brings with it numerous challenges that are not always obvious at first glance. The push for renewable energy, such as solar and wind, and the increasing digitalization of society are triggering unprecedented demand for minerals and metals.While the main objective is to reduce the carbon footprint and protect the climate, This process also puts considerable pressure on the subsoil and the natural resources beneath our feet.
In this context, Intensive mineral extraction is consolidating itself as one of the main protagonists of the energy paradigm shift.In fact, international organizations predict that up to 3.000 billion tons of minerals and metals will be needed to support the transition to clean energy sources alone, destined for renewable energy generation and storage infrastructure. This represents a significant environmental cost, because although the reduction in surface emissions is significant, intensive mining entails ecosystem and social impacts that should not go unnoticed.
The impact of renewables on mineral demand
The technological development of solar panels, wind turbines and batteries is making Materials such as copper, lithium, silver, aluminum and so-called rare earths are increasingly in demand.For example, manufacturing a 5MW wind turbine requires more than a thousand tons of concrete and large quantities of steel, copper, and aluminum. Photovoltaic infrastructure, for its part, requires around 7% of all the silver consumed globally.
The trend is clear: Spain plans to double its installed capacity in both wind and solar energy by 2030., which translates into the need to add thousands of wind turbines and solar panels to the national landscape. This growth also implies a proportional increase in the extraction, transportation and processing of raw materials.
In addition, the electrification of mobility and the expansion of the electric battery require huge quantities of lithium, graphite and other strategic mineralsDemand for lithium is expected to increase more than 40-fold by 2040, and for graphite by 25-fold, according to estimates from various international organizations. Population growth and rising consumerism are driving a projected 170% increase in mineral and rock consumption over the coming decades.
The resurgence of mining and the role of Spain
To meet this demand, The mining sector is experiencing a new boom and reorientationIn Spain alone, there are currently more than 2.600 active mines extracting a wide variety of minerals and raw materials. In recent years, national plans have been implemented to modernize mining legislation, increase controls over resource traceability, and promote recycling and material recovery, all with a focus on ensuring more efficient and sustainable exploitation.
The country stands out as a producer of key minerals such as strontium, sepiolite, gypsum, copper, and ornamental rocks, ranking among the leading producers in Europe and the world in the extraction of certain materials. Furthermore, The European Commission considers some national deposits to be strategic, which is why several projects have been candidates for EU aid with the aim of strengthening European mining autonomy in the face of dependence on imports from third countries.
Among the main challenges is the fact that even with high recycling rates, The amount of minerals needed to sustain the energy transition exceeds the reusability of materials currently in use.This is accelerating new exploration in mines previously considered depleted or of little interest, as minerals that were previously secondary have become indispensable for the manufacture of clean technologies and advanced electronic devices.
Social and labor implications of the mining boom
Mining not only represents an economic opportunity, but also has a direct impact on employment and the local economy. The sector employs more than 30.000 workers in Spain, with a wide distribution between quarries, industrial mines, and metal mining operations. The sector's turnover exceeded €3.500 billion last year, consolidating the strategic importance of mining in the current energy context.
In addition to direct employment, The reactivation of old mines and the search for new deposits can boost the economy of traditionally mining regions., although there are also voices concerned about the possible environmental and social impacts of intensive extractive activity. The challenge is to move toward a balance between meeting the demand for minerals and protecting the environment, promoting innovation, the restoration of degraded areas, and transparency in the sector.
As decarbonization and electrification shape the direction of the economy, pressure on mineral resources increases, raising questions about long-term sustainability. Legislation, circular economy and international cooperation will be key to facing these challenges and taking advantage of the opportunities offered by the energy transition.
The current situation invites us to reflect on the complexity of the green transition: As the goal of cleaner energy is pursued, intensive mineral extraction is becoming a fundamental pillar, bringing with it new ecological and economic challenges. Sustainable resource management, innovation in materials, and strengthening strategic autonomy will be crucial to ensuring that the renewable energy model avoids repeating past mistakes and achieves long-term consolidation.
