Countries racing to secure supplies of critical minerals for renewable energy infrastructure risk inflating prices and slowing the clean energy transition, researchers have warned. The uncoordinated approach to stockpiling minerals like lithium, cobalt, and rare earths threatens to undermine global climate goals by making batteries, solar panels, and wind turbines more expensive.
Demand for these minerals will surge dramatically over the coming decades. Lithium consumption alone must increase roughly tenfold by 2040 to meet net-zero targets, according to International Energy Agency projections. Cobalt and nickel requirements will similarly spike as electric vehicle adoption accelerates worldwide.
The problem lies in how nations are responding. Rather than establishing shared supply chains or coordinated procurement strategies, countries are pursuing competing stockpiles. This fragmented approach drives up prices as buyers bid against each other for limited supplies. Higher mineral costs directly translate to increased expenses for battery production, which represents the largest cost component in electric vehicles.
The minerals themselves remain geographically concentrated. The Democratic Republic of Congo controls over 70 percent of global cobalt reserves. China dominates processing of rare earth elements. Indonesia and Australia hold major lithium deposits. This concentration creates supply chain vulnerabilities that stockpiling alone cannot solve.
Researchers argue that international cooperation offers a better path forward. Coordinated investment in mining capacity, processing infrastructure, and recycling programs would increase supply more efficiently than competitive hoarding. Developing robust secondary markets for recovered minerals from end-of-life batteries could reduce dependence on new extraction by 25 percent by 2040, studies show.
The cost implications are substantial. Uncoordinated stockpiling could add $50 billion annually to clean energy infrastructure costs by 2030, according to energy transition analyses. This burden falls hardest on developing nations already struggling to finance decarbonization.
