Critical Raw Materials: The Race for Strategic Minerals
Electric vehicle batteries, wind turbine magnets, smart grid components: these green technologies all rely on a handful of critical minerals. As governments increase their climate commitments, a rarely asked question arises: who controls the resources essential for this transformation? The answer reveals a new geopolitical map, where lithium, cobalt, and rare earths become pawns in a global strategic game.
Exploding Demand
The energy transition is causing an unprecedented surge in global demand for strategic metals. According to projections from the International Renewable Energy Agency (IRENA), the need for critical minerals could more than triple by 2050 to meet international climate goals. For certain materials like lithium, graphite, or cobalt, this increase far exceeds current production levels.
This surge is due to the material intensity of low-carbon technologies. An electric car requires six times more minerals than a conventional internal combustion vehicle. An offshore wind turbine demands nine times more mineral resources than a gas-fired power plant of equivalent capacity. Smart grids, essential for integrating renewable energies, multiply the need for copper and rare earths.
Global trade in raw and semi-processed minerals surpassed $2.5 trillion in 2023, now representing over 10% of international trade. This dynamic profoundly transforms economic balances and reveals structural bottlenecks: the timeframes for establishing new mines range from five years for lithium to over seventeen years for copper, creating a critical gap between supply and demand.
Worrying Geographical Concentration
The extraction and refining of strategic minerals show a geographical concentration unparalleled in recent industrial history. China controls approximately 60% of global rare earth extraction and over 80% of their refining. This dominance extends to many links in the value chains: cobalt processing, graphite production, and battery component manufacturing.
- Cobalt: Primarily sourced from the Democratic Republic of Congo, where extraction conditions raise serious social and environmental concerns.
- Lithium: Concentrated in the triangle formed by Australia, Chile, and Argentina, which together account for nearly three-quarters of global production.
- Rare Earths: China dominates with 60% of extraction and over 80% of refining.

This concentration creates strategic vulnerabilities for importing countries. Europe imports 98% of its rare earths, 93% of its lithium, and 97% of its cobalt. The United States depends on external sources for over 80% of its critical mineral needs, a situation that concerns national security officials.
Geopolitical Tensions Intensify
This dependence clashes with an increasingly fragmented international environment. The number of trade barriers affecting critical minerals has sharply increased in recent years, according to analyses by the French Treasury. Producing countries seek to enhance the value of their resources by imposing export restrictions or demanding local processing.
China regularly uses its dominant position as a diplomatic lever. In 2010, it drastically cut rare earth exports during a dispute with Japan. More recently, Beijing introduced export controls on gallium and germanium, essential for semiconductors and military technologies.
This instrumentalization is pushing Western powers to rethink their strategies. The United States, the European Union, and Japan are multiplying initiatives to reduce their dependence:
- Massive investments in new mines in North America, Europe, and Africa
- Bilateral cooperation agreements to secure supplies (Mineral Security Partnership)
- Research programs on recycling and substitute materials
These dynamics fuel tensions that go beyond simple commercial logic. Access to strategic minerals is becoming an issue of technological sovereignty and national security, comparable to the control of oil resources in the 20th century.
Reshaping Value Chains
Facing supply risks, diversification strategies are multiplying. In 2023, the European Union adopted the Critical Raw Materials Act, which sets ambitious targets: extract 10% of its critical mineral needs within its territory, process 40%, and not depend on a single third country for more than 65% of each mineral.
The United States launched the Inflation Reduction Act, which ties electric vehicle subsidies to strict criteria on the origin of batteries and the minerals they contain. This approach explicitly aims to exclude China from American value chains while encouraging partnerships with allied countries.
Recycling emerges as a promising but still insufficient avenue. Currently, less than 1% of lithium and 30% of cobalt are recycled globally. Recycling technologies are advancing, but the available waste volumes will remain limited until the first equipment reaches end-of-life, around 2030 for first-generation batteries.
Mining projects also face major obstacles: social acceptability, environmental regulations, and the length of authorization procedures. In Europe, opening a new mine takes an average of twelve to sixteen years, compared to five years in Australia. This time lag complicates ambitions for mineral sovereignty.

A New Geoeconomy Under Construction
The energy transition is reshaping trade alliances and international power dynamics. Countries rich in critical minerals are realizing their negotiating power and seeking to maximize the added value captured within their territory. Chile, the world's largest copper producer, has nationalized part of its lithium industry. Indonesia has banned the export of raw nickel, forcing industrialists to invest locally in refining.
This dynamic transforms previously peripheral regions into major geopolitical players. Africa, which holds 40% of the world's cobalt reserves and significant shares of manganese and graphite, attracts Chinese, American, and European investments. Competition for access to these resources fuels tensions, particularly in the Democratic Republic of Congo, where mining issues intertwine with armed conflicts.
The oceans are becoming a new front. The deep seabed of the Clarion-Clipperton Zone in the Pacific contains millions of tons of polymetallic nodules rich in cobalt, nickel, and manganese. Several companies are preparing extraction operations, despite regulatory uncertainties and environmental concerns.
This geoeconomic recomposition is accompanied by increased price volatility. Lithium prices multiplied by eight between 2020 and 2022, before falling by 80% in 2023 due to Chinese overproduction and slowing demand. These brutal fluctuations complicate industrial planning and weaken the profitability of mining projects.
Major Environmental and Social Challenges
The extraction of critical minerals raises increasingly pressing ethical and environmental questions. Congolese cobalt mines employ tens of thousands of artisanal miners, including children, in dangerous conditions. Lithium extraction consumes enormous quantities of water in already arid regions of South America, threatening ecosystems and local communities.
Rare earth refining generates radioactive waste and significant chemical pollution. China long accepted these environmental costs, contributing to its dominance in the sector. The stricter standards applied in Western countries make their projects less competitive, creating a dilemma between sovereignty and environmental protection.
International organizations and NGOs advocate for responsible supply chains. Initiatives like the Initiative for Responsible Mining Assurance or the Responsible Minerals Initiative attempt to establish transparency and traceability standards. But their effectiveness remains limited given the complexity of supply networks and the economic interests at stake.
Paradoxically, the energy transition risks reproducing the extractivist patterns it claims to overcome. Replacing dependence on fossil fuels with dependence on critical minerals only solves part of the problem if extraction conditions remain socially and environmentally unacceptable.
Towards Material Sobriety?
Faced with these multiple challenges, some experts advocate for a complementary approach: reducing mineral needs rather than simply seeking to increase supply. This material sobriety would involve several levers: optimizing designs to reduce material quantities, extending equipment lifespan, and developing a circular economy.
Technological innovations could also alleviate pressure on certain minerals. Sodium-ion batteries, which require neither lithium nor cobalt, are rapidly advancing in China. Research is focusing on rare-earth-free permanent magnets for electric motors. But these alternatives often remain less efficient or more costly in the short term.
The issue of critical minerals reveals the intrinsic contradictions of the energy transition as currently conceived: how to massively decarbonize without exacerbating other ecological and social crises? This tension requires rethinking not only technologies but also consumption patterns and growth objectives that underpin transition scenarios.
The coming years will determine whether humanity can navigate these constraints. The stakes extend far beyond the simple question of raw material supply: they touch upon the very viability of an energy transformation that aims to be both rapid, just, and sustainable.
