Countries racing to secure supplies of critical minerals for renewable energy technologies risk inflating prices and slowing the global clean energy transition, researchers warn. Uncoordinated stockpiling by governments and corporations seeking to guarantee access to materials like lithium, cobalt, and rare earth elements could create artificial scarcity and drive up costs for battery production, solar panels, and wind turbines.
The concern reflects a fundamental tension in the energy transition. Shifting away from fossil fuels requires vast quantities of minerals essential for storing and generating renewable energy. A single electric vehicle battery requires roughly 30 kilograms of lithium. A single wind turbine needs between 200 and 600 kilograms of rare earth elements. As demand accelerates, countries without domestic mineral reserves compete aggressively for access, creating a zero-sum dynamic that destabilizes markets.
Researchers caution that this competitive scramble lacks coordination across nations and sectors. When multiple countries hoard supplies independently, they drive prices higher than market fundamentals justify, making clean energy technologies more expensive for consumers and utilities. Higher transition costs risk delaying decarbonization timelines and widening inequality between wealthy nations that can afford price spikes and developing countries that cannot.
The issue extends beyond price to geopolitical concentration. China controls roughly 70 percent of global rare earth element processing and major shares of lithium and cobalt refining. Stockpiling by other nations attempts to reduce this dependency, but without transparent international frameworks, the strategy backfires through redundant purchasing that wastes capital.
A more efficient approach requires coordinated investment in extraction capacity, processing infrastructure, and recycling systems across multiple countries. Such coordination would stabilize supply chains and keep mineral costs predictable. International agreements on strategic reserves, similar to those governing oil stockpiles, could replace chaotic individual hoarding.
