Copper Demand in the Energy Transition — Electrification, EVs, Renewables & Grid Upgrades

The Electrification Metal

Copper occupies a unique position among all critical minerals in the energy transition. While cobalt, lithium, and rare earths are associated primarily with specific technologies—batteries, magnets, cathodes—copper is required in virtually every component of the electrified economy. Its unmatched electrical conductivity, thermal performance, corrosion resistance, and recyclability make it physically irreplaceable across the entire spectrum of clean energy technologies. No other metal connects so many sectors of the transition: electric vehicles, charging infrastructure, wind turbines, solar panels, battery storage, power grids, transformers, data centres, and the industrial electrification of heating and manufacturing processes.

Global copper mine production in 2023 stood at approximately 22 million tonnes. Total refined copper consumption reached roughly 26 million tonnes, with the gap bridged by secondary (recycled) copper supply. For the past century, copper demand growth has tracked closely with GDP and industrialisation, growing at approximately 2 to 3 percent annually. The energy transition is now superimposing a structural demand acceleration on top of this baseline growth. The International Energy Agency projects that clean energy applications alone will require an additional 5 to 7 million tonnes of annual copper demand by 2035—an increase equivalent to building an entirely new Chile-sized copper industry on top of current production.

The implications for copper-producing regions are profound. The Central African Copperbelt—spanning the DRC and Zambia and connected to global markets via the Lobito Corridor—contains some of the highest-grade copper deposits on Earth. At a time when average global copper ore grades have fallen below 0.6 percent, the Kamoa-Kakula mine in the DRC produces ore grading above 5 percent copper. This geological advantage, combined with expanding infrastructure connectivity, positions the Copperbelt as the most important growth region for copper supply in the world.

Electric Vehicles & Copper

The electric vehicle revolution represents the single largest new source of copper demand growth in the transport sector. Every EV contains substantially more copper than a comparable internal combustion engine (ICE) vehicle, and the magnitude of this difference scales with the tens of millions of EVs projected to be manufactured annually by 2030 and beyond.

Within an EV, copper is distributed across multiple subsystems. The battery pack itself contains approximately 8 kilograms of copper in cell connectors, bus bars, and current collectors. The electric motor—typically a permanent magnet synchronous motor or an induction motor—uses 8 to 12 kilograms of copper in its stator windings. The wiring harness, which carries high-voltage power from the battery to the motor and to auxiliary systems, contains 25 to 40 kilograms of copper. Power electronics (inverter, onboard charger, DC-DC converter) add another 5 to 10 kilograms. The thermal management system, which circulates coolant through the battery and motor, uses copper tubing and heat exchangers.

Global EV sales surpassed 14 million units in 2023 and are projected to exceed 40 million units annually by 2030. At 83 kilograms of copper per BEV, 40 million vehicles would consume approximately 3.3 million tonnes of copper per year—solely for vehicle manufacturing. This represents roughly 15 percent of current total global copper consumption, dedicated to a product category that barely existed a decade ago.

Charging Infrastructure

EV charging stations represent an additional copper demand layer that sits on top of vehicle manufacturing. Every charging station requires copper for cabling, connectors, transformers, switchgear, and grid interconnection. The copper intensity varies dramatically by charger type.

The IEA estimates that the world will need approximately 15 million public charging points by 2030 to support projected EV fleets, plus tens of millions of private home and workplace chargers. When the grid connection infrastructure is included—transformers, feeder cables, and distribution upgrades—the cumulative copper demand from charging networks could reach 200,000 to 500,000 additional tonnes per year by 2030. This demand is incremental to the vehicle manufacturing copper requirement and is frequently underestimated in demand forecasts.

Renewables: Wind, Solar & Storage

Wind Energy

Wind turbines are among the most copper-intensive power generation technologies. An onshore wind turbine requires approximately 3 to 5 tonnes of copper per megawatt of installed capacity, while offshore wind turbines—which include longer submarine power cables and larger generators—require 8 to 15 tonnes per megawatt. Copper is used in the generator windings, power cables within the tower, transformer, switchgear, and the cable connecting the turbine to the grid. For a detailed breakdown of minerals used in wind energy, see our dedicated analysis.

Global wind installations are projected to reach 350 to 400 GW of annual additions by 2030 under IEA net-zero scenarios. At an average of 4 to 5 tonnes of copper per megawatt for onshore and 10 tonnes for offshore, annual wind-related copper demand could reach 1.5 to 2.5 million tonnes—roughly 7 to 10 percent of current global consumption.

Solar Energy

Solar photovoltaic systems use copper in cabling, inverters, mounting structures, and balance-of-system components. A typical utility-scale solar installation requires approximately 2 to 5 tonnes of copper per megawatt. While this is lower than wind on a per-megawatt basis, the sheer scale of projected solar deployment—potentially exceeding 500 GW of annual installations by 2030—makes solar a major copper demand driver. See our analysis of minerals for solar energy for the complete mineral profile.

Battery Energy Storage

Grid-scale battery storage systems require copper for DC bus bars, interconnection cabling, inverters, transformers, and climate control. A typical 100 MWh battery storage facility uses 40 to 80 tonnes of copper. With global battery storage deployments projected to exceed 1,000 GWh cumulatively by 2030, storage-related copper demand will grow from a small base to a meaningful demand category. This is in addition to the copper contained in the battery cells themselves.

Grid Modernisation & Transmission

The largest and most frequently overlooked category of energy transition copper demand is power grid infrastructure. Electrification of transport, heating, and industry dramatically increases the volume of electricity that must be generated, transmitted, and distributed. Existing power grids in most major economies were designed for a world of centralised fossil fuel generation and predictable demand patterns. The transition to distributed renewables, bidirectional EV charging, and electrified heating requires a fundamental upgrade of grid infrastructure at every level—from high-voltage transmission lines to local distribution transformers.

Power transformers are particularly copper-intensive. A large power transformer for grid transmission contains 10 to 50 tonnes of copper. Distribution transformers, which step voltage down for delivery to homes and businesses, each contain 50 to 500 kilograms of copper. A single country may have millions of distribution transformers in service, and the age profile of the existing transformer fleet in many developed economies means that a replacement cycle is due regardless of the energy transition. When the need for additional capacity to accommodate EVs, heat pumps, and solar feed-in is layered on top, the transformer-related copper demand becomes enormous.

Submarine and underground power cables represent another growth area. Offshore wind farms require submarine cables to connect to the onshore grid, and these cables use copper or aluminum conductors. High-voltage direct current (HVDC) interconnectors—increasingly used to link renewable energy zones to demand centres across long distances—are among the most copper-intensive infrastructure projects in the world. A single 1,000 km HVDC submarine cable can contain 5,000 to 10,000 tonnes of copper.

The IEA estimates that global investment in electricity grids must reach $600 billion annually by 2030—roughly double the 2022 level—to enable the clean energy transition. A substantial portion of this investment translates directly into copper demand. Grid-related copper consumption is projected to grow by 1 to 3 million tonnes annually by 2035, making grids collectively the single largest energy transition demand category for the red metal.

Data Centres & AI Infrastructure

An emerging and rapidly accelerating source of copper demand is the global data centre buildout, driven by the artificial intelligence revolution and the broader digitalisation of the economy. Data centres are extraordinarily power-intensive facilities that require massive copper wiring for power distribution, cooling systems, and network connectivity.

A hyperscale data centre with 100 MW of power capacity may contain 2,000 to 4,000 tonnes of copper in its power distribution infrastructure, busbars, transformers, generators, uninterruptible power supply systems, and cabling. The power cable connecting a data centre campus to the grid can itself consume hundreds of tonnes of copper. The dedicated substations and grid reinforcements needed to supply data centres with reliable power add further copper demand.

Global data centre power demand is projected to double or triple by 2030, driven primarily by the compute requirements of AI training and inference. Major technology companies—Microsoft, Google, Amazon, Meta—have announced combined data centre investment exceeding $200 billion per year. Each new data centre facility generates copper demand both directly (within the facility) and indirectly (grid upgrades to supply it with power). Goldman Sachs has estimated that data centres alone could add 500,000 to 1,000,000 tonnes of annual copper demand by 2030—a demand category that was essentially nonexistent in copper market forecasts as recently as 2020.

This new demand vector is particularly significant because it arrives simultaneously with EV, renewable, and grid copper demand growth. The data centre buildout and the energy transition are converging on the same constrained copper supply base, amplifying the scale of the projected deficit.

Demand Projections to 2035

The cumulative impact of electrification across transport, power generation, grid infrastructure, and digital infrastructure creates a demand trajectory that the copper mining industry has never previously confronted. Multiple credible forecasters have published projections that converge on a similar conclusion: the world will need substantially more copper than it currently produces, and the gap will widen through the decade.

These incremental demands sit on top of baseline copper consumption of approximately 22 to 24 million tonnes per year from traditional applications (construction, industrial equipment, consumer electronics). Total global copper demand under a strong electrification scenario could reach 35 to 40 million tonnes per year by 2035—an increase of 50 to 75 percent from current levels over a period of just 12 years.

S&P Global published a landmark study projecting that total copper demand would need to double from approximately 25 million tonnes in 2022 to 50 million tonnes by 2035 under a net-zero pathway. Even the most conservative scenarios, which assume slower EV adoption and less aggressive grid investment, project demand growth of 25 to 30 percent by 2035. There is no plausible energy transition scenario in which copper demand does not increase dramatically.

Supply Response & Deficit Outlook

The copper mining industry faces structural constraints that make it exceptionally difficult to match the pace of demand growth. Developing a major new copper mine takes 10 to 15 years from initial exploration to first production. The pipeline of mines currently under construction or in advanced development will add perhaps 2 to 3 million tonnes of annual capacity by 2030—far short of the projected demand increase.

Several factors compound the supply challenge. Average ore grades at existing mines are declining—the global average has fallen from over 1.5 percent copper in the 1990s to below 0.6 percent today. Lower grades mean more rock must be mined and processed to produce each tonne of copper, increasing costs, energy consumption, water usage, and environmental impact. Permitting timelines for new mines have lengthened in most jurisdictions due to stricter environmental regulation, indigenous rights considerations, and community opposition. Water scarcity is becoming a binding constraint in Chile and Peru, two of the world's largest producers. Labour disputes, resource nationalism, and political instability affect supply reliability in several key producing countries.

The result is a widely forecast supply deficit. Most copper market analysts project deficits emerging between 2025 and 2027, widening through the decade. The scale of the projected deficit varies by forecaster and scenario, but estimates range from 2 to 8 million tonnes per year by 2035. A deficit of this magnitude would be unprecedented in the history of the copper market and would imply sustained high prices, intensified competition for supply, and potential bottlenecks for the energy transition itself.

Recycling provides a partial offset. Secondary copper from recycled electrical cable, electronics, and industrial scrap currently supplies approximately 4 million tonnes per year, or roughly 16 percent of total refined supply. Improved collection rates and more efficient recycling technology could increase secondary supply, but even aggressive recycling scenarios add only 1 to 2 million tonnes of incremental annual supply by 2035—meaningful but insufficient to close the projected deficit.

Lobito Corridor Implications

The Lobito Corridor's strategic importance is directly proportional to the scale of the global copper supply deficit. As the gap between demand and available supply widens, the minerals produced in the DRC-Zambia Copperbelt become increasingly essential—and the infrastructure that moves those minerals to market becomes increasingly valuable.

The DRC is the world's fastest-growing major copper producer. Kamoa-Kakula, operated by Ivanhoe Mines, is ramping toward a production target of over 600,000 tonnes of copper annually at full build-out, which would make it one of the largest copper mines in the world. Tenke Fungurume, Deziwa, and multiple development-stage projects add further production potential. Total DRC copper output could exceed 3 million tonnes annually within a decade, up from approximately 2.5 million tonnes in 2023.

Zambia has set a national target of 3 million tonnes of annual copper production, a tripling from current output. Mines including Kansanshi, Sentinel, and the KoBold-backed Mingomba discovery are central to this ambition. Combined DRC-Zambian copper production growth of 3 to 5 million additional tonnes per year would represent the single largest incremental supply response available to the global market.

Without the Lobito Corridor, this Copperbelt production growth is constrained by logistics bottlenecks. The existing southbound export route through South Africa's ports is long, congested, and expensive. The Dar es Salaam route through Tanzania faces its own capacity limitations. The Lobito Corridor—linking Copperbelt mines to the port of Lobito on Angola's Atlantic coast—provides a shorter, faster, and more direct route to European and North American markets. It is not an exaggeration to state that the corridor's completion and capacity expansion are preconditions for the Copperbelt to fulfil its potential as the supply response to the global copper deficit.

The convergence of accelerating demand, constrained supply, and critical infrastructure development makes copper from the Lobito Corridor not merely a commercial commodity but a strategic input to the energy transition itself. The US DFC, the EU's Global Gateway, and private investors backing the corridor are, in effect, investing in the physical infrastructure that determines whether the world's copper supply can keep pace with the demands of electrification.
