Iceland is known for producing aluminum, seafood, and geothermal energy on a scale that far outweighs its tiny population of roughly 380,000 people. The country has turned its volcanic geology, cold ocean waters, and cheap renewable power into a surprisingly diverse set of exports and innovations, from smelted metals to groundbreaking genetic research.
Aluminum and Metal Smelting
Iceland’s single largest manufacturing export is aluminum. In 2021, the country produced roughly 730,000 metric tons of primary aluminum, and exports of aluminum and aluminum products totaled about $2.24 billion. That made aluminum responsible for around 33% of Iceland’s total exported goods by value.
Iceland doesn’t mine the raw material (bauxite) domestically. Instead, it imports bauxite and processes it using the country’s abundant geothermal and hydroelectric power. Smelting aluminum is extraordinarily energy-intensive, so Iceland’s cheap, renewable electricity gives it a major cost advantage. Three large smelters operated by international companies handle most of the output, making Iceland one of the world’s top aluminum producers per capita by a wide margin.
Seafood and Marine Products
Fishing has been central to Iceland’s economy for centuries, and it remains a major force. In 2023, fishery exports were valued at $2.9 billion, up from $2.2 billion a decade earlier. Cod is the single biggest exported species, accounting for about 20% of total export volumes. Fishmeal and fish oil together represent roughly 23% of export volumes, though they bring in a smaller share of revenue (around 12% of value) because they sell at lower prices per ton than whole or processed fish.
Beyond cod, Iceland exports significant quantities of haddock, pollock, redfish, and herring. The country manages its fisheries through a strict quota system designed to prevent overfishing, which has helped maintain stock levels even as global fish populations have declined elsewhere. Icelandic seafood reaches markets across Europe, North America, and Asia.
Geothermal and Renewable Energy
Nearly 100% of Iceland’s electricity comes from renewable sources, split between hydropower and geothermal energy. The country sits on the Mid-Atlantic Ridge, giving it access to volcanic heat just below the surface. Geothermal plants generate electricity and pipe hot water directly into homes for heating, which is why Icelanders pay some of the lowest energy bills in Europe.
This cheap, clean energy is the foundation for Iceland’s aluminum industry and its growing role in data center hosting. Tech companies have built server farms in Iceland to take advantage of naturally cool air for cooling systems and renewable power for operations. The energy surplus also supports Iceland’s position in an emerging field: carbon capture technology. The Orca facility near Reykjavik uses direct air capture to pull CO₂ from the atmosphere and inject it into basalt rock underground, where it mineralizes permanently. The plant eliminates about 4,000 tons of CO₂ per year, a small amount (equivalent to taking roughly 800 cars off the road) but a working proof of concept that has attracted global attention.
Genetic and Medical Research
Iceland produces something less tangible but globally significant: genetic data. The country’s small, relatively homogeneous population and detailed genealogical records going back centuries make it an ideal laboratory for studying the genetics of disease. The Reykjavik-based company deCODE Genetics has sequenced the genomes of a large portion of Iceland’s population and linked that data to health records.
This work has produced concrete medical findings. Researchers identified mutations in the BRCA2 gene that appear in about 0.4% of Icelanders but are negligible in most other populations, deepening understanding of inherited breast cancer risk. Studies using the Icelandic dataset found a strong link between certain genetic variants in a gene called ABCA7 and Alzheimer’s disease. That gene plays a role in how the brain clears away dead cells and harmful substances. Other research connected a specific gene to atrial fibrillation, one of the most common heart rhythm disorders in Iceland. These findings have informed medical research worldwide and helped pave the way for large-scale genomic studies in other countries.
Wool and Knitwear
Icelandic sheep have been bred in isolation for over a thousand years, producing a distinctive dual-coated wool: a coarse, water-resistant outer layer and a soft, insulating inner layer. This wool is the basis for the lopapeysa, the iconic Icelandic sweater with its circular yoke pattern, which has become both a cultural symbol and a tourist commodity. Iceland’s wool exports are relatively modest in dollar terms (projected around $3.5 million by 2026), but the knitwear tradition punches above its weight in cultural visibility. Hand-knitted sweaters remain a staple souvenir, and Icelandic wool yarn is exported to knitters worldwide.
Bottled Water
Iceland also exports its naturally filtered glacial and spring water. Brands market the water’s purity, which comes from filtration through layers of volcanic lava rock. The United States is the largest destination, absorbing nearly 58% of Iceland’s mineral water exports in 2023, followed by Canada and the United Kingdom. Total export value is small, under $2 million annually, but the products have carved out a recognizable niche in the premium bottled water market.
Music, Film, and Creative Industries
Iceland has produced a disproportionate number of internationally recognized musicians relative to its population. Björk, Sigur Rós, and Of Monsters and Men all emerged from Reykjavik’s small but active music scene. The country’s dramatic landscapes have also made it a popular filming location, with productions including major scenes from Game of Thrones, Interstellar, and several Marvel films using Icelandic glaciers, lava fields, and black sand beaches as backdrops. The Icelandic government offers film production rebates that have helped grow this sector into a meaningful source of revenue and international visibility.
Tourism itself became one of Iceland’s biggest “products” after the 2008 financial crisis, when a devalued currency made the country affordable for foreign visitors. Annual tourist arrivals grew from around 500,000 in 2010 to over 2 million before the pandemic, generating billions in revenue and reshaping the economy in the process.
