Spain holds one of the most diverse natural resource portfolios in Europe, spanning metallic minerals, vast agricultural land, marine fisheries, and some of the continent’s strongest renewable energy assets. While the country has shifted away from fossil fuels in recent years, its mineral wealth, food production, and energy capacity make it a significant player on the global stage.
Metallic and Industrial Minerals
Spain’s geology gives it access to a wide range of metallic minerals, including copper, zinc, lead, gold, silver, tungsten, nickel, and iron. In 2019, Spanish mines produced roughly 122,300 metric tons of copper concentrate (by copper content), 187,900 metric tons of zinc, and nearly 30,000 metric tons of lead concentrate. The country also produced about 13.6 million metric tons of raw steel that year. Some of these outputs have swung dramatically from year to year: mined lead jumped 200% in 2019, and zinc rose 77%, reflecting the cyclical nature of extraction and demand.
Beyond metals, Spain is a global heavyweight in gypsum, the calcium sulfate mineral used in construction plaster, drywall, and cement. With production of 11.5 million tonnes in 2009, Spain ranked third in the world behind China and Iran and led all of Europe. That output came from 118 open-pit quarries scattered across the country, with much of the gypsum exported to the United Kingdom, Nigeria, Venezuela, and the United States. The richest deposits sit in central and eastern Spain, where ancient evaporite formations cover more than 13,500 square kilometers. Additional deposits appear in the Ebro basin and the La Mancha region.
Agricultural Land and Food Production
Spain’s warm, Mediterranean climate and extensive farmland support several world-leading agricultural sectors. The most prominent is olive oil. Spain produces roughly half of the entire global olive crop, making it by far the largest supplier on Earth. Andalusia, in the south, accounts for most of this output, with orderly groves stretching across millions of hectares.
Wine grapes are another pillar. Spain has more vineyard acreage than any other country, with major growing regions including La Rioja, Castilla-La Mancha, and Catalonia. Citrus fruits, especially oranges and lemons grown along the Mediterranean coast in Valencia and Murcia, round out the top tier. Spain is also the world’s largest producer of organic olives and grapes, and the third-largest producer of organic citrus fruits, reflecting a strong push toward sustainable farming practices.
Renewable Energy Resources
Spain’s geography delivers abundant wind and sunshine, and the country has invested heavily in turning those into electricity. In 2024, 56.8% of all electricity generated in Spain came from renewable sources like wind, solar, and hydropower. That marked a 10.3% increase over the previous year and set a national record.
Wind power led the generation mix at 23.2% of total output, followed by solar photovoltaic at 17% and hydroelectric at 13.3%. The country added 7.3 gigawatts of new solar and wind capacity in 2024 alone, the highest single-year increase ever recorded. Solar photovoltaic panels now represent 25.1% of Spain’s total installed generation capacity, making it the single largest technology in the fleet, narrowly ahead of wind at 24.9%. As of the end of 2024, total installed capacity reached 129 gigawatts, with renewables accounting for 66% of that figure.
Hydropower, while smaller than wind and solar, still plays a meaningful role. Spain generated about 29,600 gigawatt-hours from hydroelectric plants in 2021, drawing on a large network of reservoirs and dams built primarily during the mid-20th century. These reservoirs also serve as critical water storage for agriculture and drinking water in a country that regularly faces drought.
Fisheries and Marine Resources
With coastline along both the Atlantic Ocean and the Mediterranean Sea, Spain has long been one of Europe’s fishing powerhouses. In 2021, the Spanish fishing fleet numbered around 8,730 vessels, the third largest in the European Union. The fleet ranges from small coastal boats to large deep-sea trawlers that operate as far away as the Indian Ocean and the waters off West Africa.
By value, the most important catches are tuna, albacore, and needlefish, followed by cod, hake, herring, sardines, and anchovies. Shellfish are equally significant: prawns, shrimp, squid, cuttlefish, and octopus all generate substantial revenue. Spain is also one of Europe’s largest consumers of seafood per capita, so a sizable portion of the catch goes directly to the domestic market.
Fossil Fuels: A Diminishing Role
Spain was never a major fossil fuel producer, and what little it had is now largely gone. The country stopped producing coal entirely in 2019, following a government deal with unions and industry that directed 250 million euros toward affected mining communities. The Just Transition Strategy that accompanied the closures established a framework for retraining workers and attracting new investment to former coal regions, particularly in Asturias, León, and Teruel.
Domestic natural gas and oil extraction have always been minimal. Spain imports the vast majority of its fossil fuels, which has been a key driver behind the aggressive shift toward renewables. Combined-cycle gas plants still contributed 13.6% of electricity generation in 2024, but the trajectory is clearly downward as solar and wind capacity expands.
Lithium and Critical Mineral Deposits
One resource that could reshape Spain’s economic future is lithium, the lightweight metal essential for electric vehicle batteries and energy storage systems. The Extremadura region in western Spain sits atop significant lithium deposits, and the regional government has declared the mineral a resource of “general interest” across its entire territory. Two combined lithium mining and processing projects are currently planned, alongside two battery cell manufacturing plants.
If these projects move forward, Spain could become one of Europe’s few domestic lithium suppliers, reducing the continent’s dependence on imports from Australia, Chile, and China. The timeline remains uncertain, as mining proposals in the region have faced environmental scrutiny and local opposition, but the strategic importance of the deposits keeps them high on national and EU agendas.
