Electric everything won't happen on schedule
The transition to a net-zero economy is a race against the physical limits of mining and the grid, not a question of capital or technology.
The push toward “electric everything” once looked like a straightforward solution to climate goals and energy security. Cars, trucks, home heating, industrial processes, and now entire digital economies are shifting to electricity at a speed few forecasters anticipated even five years ago. Solar panels and wind turbines have delivered cost reductions and capacity additions, yet the full picture emerging from 2025 and early 2026 data reveals a more complex reality: the materials and infrastructure required to deliver reliable power at this scale are bumping into some of the tightest supply constraints the energy sector has seen in decades.
Global electricity demand is entering what the International Energy Agency aptly calls the “Age of Electricity.” Under today’s stated policies, consumption is on track to rise by roughly 40 percent between now and 2035, with even higher growth in ambitious climate scenarios. Electric vehicle sales continue their upward march, heat pumps are displacing gas boilers in many countries, and industrial electrification is gaining momentum. Layer on top the explosive growth of data centers, many of them dedicated to training and running artificial intelligence models, and the numbers become striking. In the United States, the Energy Information Administration now projects the strongest four-year period of electricity demand growth since 2000, with large computing centers responsible for most of the upward revision. Globally, data-center electricity use is expected to more than double in some forecasts, adding hundreds of terawatt-hours annually.
Every electric vehicle uses roughly four times as much copper as a conventional car. With millions of new EVs entering the market each year, this intensity multiplier is rapidly scaling global copper requirements. Every kilometer of new high-voltage transmission line requires substantial copper and aluminum. Every transformer, switchgear unit, and charging station adds to the sum. Renewables themselves, while lighter on fuel, are material-intensive when scaled to replace baseload generation. The result is a surge in demand for a handful of critical minerals that the mining industry has never been asked to deliver at this speed and volume before.
Copper stands out as the clearest example of this emerging bottleneck. Global refined copper demand stood at about 27 million metric tons in 2024. Projections see it climbing to 42 million metric tons by 2040, representing a 50 percent increase driven by grids, electric vehicles, renewables, and data-center infrastructure. Yet primary mine supply, currently around 23 million metric tons, is forecast to peak near 27 million tons around 2030 before sliding back toward 22 million tons as existing deposits deplete and ore grades decline. Without a wave of new mines and processing capacity, analysts point to potential shortfalls approaching 10 million tons annually by 2040. The International Energy Agency’s Global Critical Minerals Outlook 2025 is even more direct: under current project pipelines, copper supply could lag demand by as much as 30 percent by 2035. Declining ore grades, rising capital costs, lengthy permitting processes (often 15–20 years from discovery to production), and concentrated refining capacity (with one country dominating much of the processing) all compound the challenge.
Lithium has a similar story, with a somewhat different timeline. Demand nearly tripled between 2020 and 2024, reaching 205 kilotons of lithium content, and is projected to triple again by 2035 under stated policies. Electric vehicles account for the vast majority of that growth. Near-term supply looks adequate thanks to rapid expansions in Australia, Chile, and Argentina, but the IEA warns that markets could slip into deficit by the early 2030s unless dozens of additional projects come online on schedule. Nickel, cobalt, graphite, and rare earth elements face their own pressures, though lithium-ion battery chemistry shifts toward LFP (lithium iron phosphate) have eased some cobalt and nickel demand in the passenger-vehicle segment. Still, heavy-duty trucks, stationary storage, and wind-turbine magnets keep overall requirements climbing.
High prices, however, are the ultimate engine of creativity and innovation. Copper prices have already surged past $13,000 per tonne, briefly exceeding $14,000 in early 2026, as markets begin pricing in the emerging deficits. As copper and lithium enter these “crunch” years, the era of material substitution is beginning in earnest. We are seeing a shift where aluminum (despite being less conductive) is increasingly displacing copper in high-voltage transmission lines and even some EV motor windings due to its lower cost and abundance. Also the rise of sodium-ion technology offers a “safety valve” for stationary storage, bypassing the lithium-nickel-cobalt squeeze entirely by using common salt. These shifts won’t eliminate the shortage, but they redefine it. The transition is moving away from a desperate scramble for a few “magic” minerals and toward a more flexible, diversified material palette that favors whichever atom is available and affordable.
Grids add another layer of complexity. Transmission and distribution networks are the circulatory system of the electric economy, yet investment has lagged generation additions for years. Connection queues in the United States alone exceed 1,400 gigawatts of proposed generation and nearly 900 gigawatts of storage. Transformer lead times have stretched to two or three years in many markets, driving sharp price increases. China’s aggressive grid build-out has absorbed enormous quantities of copper in recent years, tightening global markets further. When supply fails to keep pace, the consequences are visible: rising curtailment of renewables, negative wholesale prices during surpluses, and even blackouts during extreme cases when heat waves or calm periods coincide with peak demand. Events in Chile and the Iberian Peninsula in 2025 served as stark reminders that modern economies cannot tolerate prolonged power interruptions.
None of this diminishes the genuine progress underway. Battery prices continue to fall, solar and wind installations set new records annually, and electric-vehicle adoption is reshaping oil markets. Recycling is scaling up and could cover a meaningful share of future needs, reaching potentially 25 percent or more of copper demand by 2040 if collection systems improve. New mining projects in the Americas, Australia, and parts of Africa are advancing, supported by policy incentives in the United States, European Union, and elsewhere. Technological innovations, from more efficient motors to sodium-ion batteries and advanced conductors, offer pathways to reduce intensity. Demand response, smart charging, and vehicle-to-grid systems can help smooth peaks without requiring proportional increases in generation or materials.
The question is timing. Mine development still averages 15–20 years from exploration to first production. Permitting reform, streamlined environmental reviews that maintain high standards, and international cooperation on responsible sourcing will determine whether supply can catch up before costs spike or ambitions are scaled back. Diversifying refining capacity beyond current concentrations and boosting recycling infrastructure are equally urgent. In parallel, maintaining a role for firm low-carbon sources such as nuclear and geothermal can reduce pressure on variable renewables and their associated storage and grid requirements.
Independent research consistently shows that the energy transition is no longer constrained primarily by technology or even capital in the broadest sense. The binding constraints are increasingly physical: the speed at which we can extract, process, and deliver the metals that turn electrons into useful work. Electric everything brings enormous promise (lower emissions, greater energy security, and new economic opportunities), but it will only deliver if we treat the material foundations of that future with the same seriousness we have applied to deployment of solar panels and batteries. The next decade will test whether policymakers, investors, and industry can align on the practical steps needed to close the gap. The lights, the motors, the servers, and ultimately the climate goals all depend on getting this right.
