A new Oakland Institute analysis challenges the widely held claim that a dramatic expansion of mining is an unavoidable cost of replacing fossil fuels. Drawing on International Energy Agency (IEA) data, the Oakland Institute calculated that wind, solar, renewable-power networks, grid batteries and electric vehicles accounted for only 26% of combined 2024 demand for copper, lithium, nickel, cobalt, graphite and magnet rare earths. The remaining 74% was attributed to construction, conventional transport, industrial machinery, defense, electronics and other uses. The calculation reflects consumption in 2024 and cannot establish which industries will drive future demand.

The metals in question long predate the energy transition. Copper has been a staple of wiring, plumbing and heavy industry for more than a century, nickel is primarily consumed as an alloying input for stainless steel, and rare earths are used in permanent magnets found in everything from consumer electronics to precision-guided munitions — a breadth of end uses that helps explain why demand persists even when clean-energy policy weakens.

According to Oakland's breakdown, uses outside renewable power and electric vehicles accounted for 83% of nickel demand, 79% of magnet rare-earth demand, 71% of copper demand, and 68% of both cobalt and graphite demand in 2024. Construction alone consumed 30% of global copper, while stainless-steel production took roughly two-thirds of global nickel.

The IEA's Net Zero by 2050 roadmap (report) projects that the number of battery-electric, plug-in hybrid and fuel-cell cars and vans worldwide will rise from 11 million in 2020 to almost 2 billion in 2050. Using the IEA's mineral-demand data, Oakland calculates that EVs would consume 15.7 million metric tons of copper, lithium, nickel, cobalt, graphite and magnet rare earths in 2050 — 23% of the projected 68.2-million-ton combined total.

A team including researchers from the University of California, Davis, modeled four pathways to zero-emissions personal transportation in the United States, separately varying battery size, warranty periods and recycling rates (study). The study found that combining lower vehicle ownership, smaller batteries and best-case recycling could cut annual lithium demand in 2050 by as much as 92% compared with the most lithium-intensive combination.

The UC Davis model also found that smaller EV batteries alone could reduce annual lithium demand for U.S. light-duty vehicles by as much as 42% in 2050, even if car dependence continued unchanged. The IEA estimates that rightsizing EV batteries, adopting alternative chemistries and expanding recycling could together reduce global lithium demand by 25% in 2030 under its net-zero scenario — a saving roughly equal to current global lithium production.

Under the IEA's net-zero scenario, recycled supplies could reduce primary copper and cobalt requirements by 30% in 2040 and primary lithium and nickel requirements by 15%. Without increased recycling and reuse, the mining investment required to meet projected demand would be one-third higher.

Oakland's 74% figure describes mineral consumption in 2024, and the IEA expects clean-energy technologies to account for much of the growth thereafter (Global Critical Minerals Outlook 2024). Under the IEA's Net Zero Emissions Scenario, mineral demand from clean-energy technologies nearly triples between 2023 and 2030. Under the less demanding Announced Pledges Scenario, anticipated mine supply from existing projects, projects under construction and projects judged highly likely to proceed would meet 70% of copper demand and 50% of lithium demand in 2035 — a gap that forms the stated rationale for new mine development.

Meanwhile, U.S. policy is pushing mineral production for reasons that have little to do with climate. At the February 2026 Critical Minerals Ministerial (transcript), U.S. officials identified missile-defense systems, artificial intelligence, advanced manufacturing and economic security as reasons to increase mineral output. Vice President JD Vance proposed a preferential trading bloc using price floors and adjustable tariffs, while other administration officials promoted federal loans, equity investments and mineral stockpiles. Neither renewable energy nor decarbonization appeared in the opening remarks.

The administration's reduced emphasis on clean-energy deployment has not diminished its mineral agenda. "That priority for the Trump administration doesn't change at all," Tom Moerenhout, adjunct associate professor at Columbia University's School of International and Public Affairs, told the Associated Press. Defense procurement, artificial intelligence, manufacturing and competition with China give Washington separate reasons to finance additional production.

In January, the U.S. International Development Finance Corporation closed a $600-million investment in a $1.8-billion consortium established to finance critical-mineral projects (press release). The DFC also reported that Congo's state-owned mining company had sold and begun shipping approximately 100,000 tons of copper committed to the United States, with another 50,000 tons planned for Saudi Arabia and the UAE.

Extraction, however, faces geographic and political complications. Much of the mining encouraged by these policies would take place near communities with recognized rights over the land. A Nature Sustainability study mapped 5,097 current and prospective projects containing energy-transition minerals and found that 54% were on or within 10 kilometers of Indigenous peoples' land, while 33% were on or within 10 kilometers of peasant land (study).

The advertised need for hundreds of new mines is therefore not simply the material cost of replacing fossil fuels. It includes minerals for weapons, data centers, construction and conventional industry, as well as the cost of expanding the global fleet of battery-electric, plug-in hybrid and fuel-cell cars and vans from 11 million in 2020 to almost 2 billion in 2050. Smaller batteries, fewer cars and higher recycling rates would reduce the amount of new ore required. UNCTAD says 250 new copper, lithium, nickel and cobalt mines are needed to meet emissions targets (statement), yet Oakland's analysis (report) finds that most current demand for those metals comes from industries outside renewable power and electric vehicles.
