The Future of Copper Demand: What Power, EV, and Renewables Growth Means for Industrial Buyers

There is a metal at the center of nearly every major infrastructure program underway on earth right now — the power grid being rebuilt to handle surging electricity demand, the electric vehicle fleet being deployed across every major market, the offshore wind arrays going up along coastlines, the data centers being constructed at unprecedented speed to support AI workloads. That metal is copper. And what is becoming increasingly clear, from the IEA to S&P Global to Wood Mackenzie, is that the world is consuming copper on a trajectory that current and foreseeable mining supply cannot match. For industrial buyers who depend on copper bus bar, copper pipe, copper coil, or copper-wound components, this is not a future problem. The structural conditions shaping supply tightness, price volatility, and procurement difficulty in the 2030s are already forming today.

This article examines the demand vectors driving the coming copper surge, the supply constraints that make meeting that demand genuinely difficult, and what procurement teams and engineering organizations should be doing right now in response.

The Scale of What Is Coming

Start with the aggregate numbers, because they are arresting. Global copper demand is projected to rise 50% by 2040, growing from 28 million metric tons today to 42 million, driven by four primary vectors: core economic demand, the energy transition — comprising renewables, EVs, and grid expansion — AI and data centers, and defense modernization.

The energy transition vector alone is the most consequential in absolute terms. Energy transition demand — from electric vehicles, battery storage, renewable power capacity, power transmission and distribution, and electrification in developing economies — commands the largest share of projected demand growth, increasing by more than 7 million metric tons to a total of 15.7 million metric tons by 2040. Demand from just core economic demand and energy transition combined will exceed copper supply by more than 7 million metric tons in 2040.

S&P Global, whose comprehensive January 2026 study Copper in the Age of AI examined the full supply-demand picture through 2040, put the implications plainly:

"Copper is the great enabler of electrification, but the accelerating pace of electrification is an increasing challenge for copper. Economic demand, grid expansion, renewable generation, AI computation, digital industries, electric vehicles and defense are scaling all at once — and supply is not on track to keep pace."

That is the environment industrial buyers are operating in — not a cyclical tightening that resolves itself over a quarter or two, but a structural realignment of the entire copper market.

Demand Vector 1: Power Grid Modernization

The single largest source of incremental copper demand through 2030 is not EVs or solar panels — it is the grid itself. Electrical infrastructure modernization requires copper at every stage: transmission conductors, transformers, switchgear bus bar, distribution hardware, and the substations connecting generation to load.

The IEA expects copper needs from electricity networks to grow from 4.1 million metric tons in 2023 to 6.2 million metric tons by 2035, an increase of 49%. Copper demand for solar panels is expected to rise by 43% and for wind power by 38% over the same period.

The fastest-growing segment within grid-related copper demand is grid battery storage. Grid battery storage is expected to see copper demand surge by 557% to 2035 as the need for energy storage increases. Battery storage systems require copper bus bar for cell interconnections, inverter connections, and AC distribution — exactly the product categories where Maverick Metals operates.

In the United States specifically, the infrastructure situation is acute. What started as a squeeze has gradually morphed into a crisis, driven by years of underinvestment in domestic manufacturing, a sudden surge in post-pandemic construction and electrification, and volatility in copper markets, which pushed lead times for large power and generator step-up transformers beyond historical norms.

Since 2019, Wood Mackenzie estimates that US power and distribution transformers have seen demand surge by 116% and 41%, respectively. Supply deficits for power transformers and distribution transformers hit 30% and 10%, respectively, in 2025. Each of those transformers contains copper windings — and the transformer shortage is, at root, partly a copper supply chain problem.

Globally, grid investment is scaling to address the deficit. Global grid investment reached a record $470 billion for the first time in 2025. The US has the highest levels of grid investment at $115 billion, or a quarter of the worldwide total. Investment in transmission is projected to grow at almost twice the rate of distribution, with a compound annual growth rate of 16% between 2024 and 2027 for transmission versus 9% for distribution.

Every dollar of that investment consumes copper. For buyers of copper bus bar, copper flat bar, and copper for switchgear and switchboard applications, grid investment is not an abstract macroeconomic trend — it is the order backlog at every electrical equipment manufacturer they supply.

Demand Vector 2: Electric Vehicles

The EV transition is the most visible copper demand driver, and the numbers underpinning it are stark. A battery electric vehicle contains roughly 83 kilograms of copper, compared to 23 kilograms in a conventional internal combustion engine vehicle. Hybrid electric vehicles require 40 kg, plug-in hybrids 60 kg. Battery-powered electric buses require between 224 and 369 kilograms depending on battery size.

Copper has applications throughout EVs, including wiring looms, winding wire for motors, energy storage — including foil and bus bars in batteries — and power cables. As a result of its naturally high conductivity, copper is the ideal material for the high-speed data wires needed in vision systems and sensors.

The copper-intensive components in an EV are exactly those where substitution with aluminum or other materials is most difficult: motor windings, battery cell interconnect bus bars, inverter connections, and charging infrastructure cabling. A fully electric vehicle can use up to a mile of copper wiring. An aluminum cable needs to have a cross-sectional area double the size of any copper equivalent to conduct the same amount of electricity — making copper the superior choice wherever space and thermal performance are constrained.

It is true that copper intensity per vehicle has declined over the past decade as manufacturers optimize designs. In 2015, each EV used about 99 kg of copper, but by 2030, that number is expected to fall to around 62 kg as wiring harness and bus bar designs become more efficient. But this reduction in per-vehicle copper content is being overwhelmed by the sheer growth in vehicle volumes. In 2015, the global EV sector needed about 56,000 tonnes of copper, and by 2030, that demand is expected to reach over 2.5 million tonnes — a 44-fold increase driven by the explosive growth in EV production.

Beyond the vehicles themselves, the charging infrastructure buildout is a massive independent copper demand driver. The number of EV charging ports is predicted to grow from 3.2 million in 2021 to 152.3 million in 2040, resulting in an additional 978,000 tonnes of copper needed for charging infrastructure in 2040. Each fast-charging station connects to the grid through copper-wound transformers, copper bus bar distribution panels, and copper feeder cables. The charging infrastructure buildout is, in copper terms, a sub-grid construction program being executed in parallel with the main grid modernization effort.

Demand Vector 3: Renewable Energy Generation

Renewable energy generation requires substantially more copper per unit of power capacity than the fossil fuel generation it replaces. While conventional power requires approximately 1 tonne of copper per installed megawatt, renewable technologies such as wind and solar require four to six times more copper per installed megawatt. This is because copper is spread over much larger land areas, with power and grounding cables running far to connect components that are widely dispersed.

The copper intensity differences between generation types are significant and application-specific. A three-megawatt wind turbine can contain up to 4.7 tons of copper, with 53% coming from cable and wiring, 24% from turbine and power generation components, 4% from transformers, and 19% from turbine transformers. Onshore wind farms use approximately 7,766 lbs. of copper per MW. Offshore wind installation uses 21,068 lbs. of copper per MW — the cabling of the offshore wind farms accounts for the bulk of that figure.

The offshore wind sector deserves particular attention. Offshore wind accounts for nearly 40% of copper demand from wind despite accounting for only 20% of total wind capacity additions — a reflection of the far greater cabling requirements of submarine interconnection. As the global offshore wind pipeline grows rapidly — driven by European and Asian government programs — the copper implications are disproportionate to the installed capacity numbers.

For solar PV, the copper requirement is concentrated in the inverter connections, DC combiners, and the grounding and collection infrastructure rather than in the panels themselves. A utility-scale solar installation contains approximately 5.5 tons of copper per megawatt of installed capacity, with the collection system and inverter bus bars accounting for the largest shares. The IEA reports that renewable energy infrastructure, including solar and wind power, needs 2.5 to 7 times more copper than fossil fuel-based technologies, depending on whether wind installations are onshore or offshore.

The cumulative effect of the renewable energy buildout on copper demand is substantial. Power grid modernization and renewable generation facilities together will need an additional 7.2 million tonnes of copper by 2030, with grid infrastructure alone accounting for 4.7 million tonnes and renewable generation facilities an additional 2.5 million tonnes.

The Emerging Demand Vectors: AI, Data Centers, and Defense

Two vectors that were not in the copper demand picture five years ago are now becoming significant in their own right, and procurement teams should not underestimate their compounding effect on available supply.

AI and data centers represent a key new demand vector, given data centers' electricity intensity, their direct copper use in power distribution, and the rapid growth of the industry. S&P Global expects total installed data center capacity to reach approximately 550 gigawatts by 2040 — more than five times 2022 levels. Each megawatt of data center capacity requires between 27 and 33 tonnes of copper for power distribution infrastructure, including bus bar systems, transformers, and the dense power distribution units that feed compute racks.

AI data centers alone could potentially consume 250–550 thousand tonnes of copper annually by 2030, representing 1–2% of global demand. That figure, while seemingly modest as a percentage of total consumption, represents new demand entering a market that is already structurally undersupplied.

Defense modernization is the other emerging vector. Global defense spending could double to $6 trillion by 2040 amid increased international tensions and the emergence of new threats. AI and data center demand combined with defense demand are each expected to roughly triple by 2040, representing a combined 4 million metric tons of additional copper demand.

Why Supply Cannot Keep Up

On the other side of this demand equation sits a mining industry that is, structurally, not positioned to respond fast enough. The constraints are geological, capital-related, and regulatory — and they compound one another.

Copper ore grades have declined 40% since 1991. Mine development timelines now average 17 years from discovery to production. Only 14 new copper deposits have been discovered in the past decade, compared to 225 in the previous 23 years. The discovery pipeline that would theoretically feed production in the 2040s is essentially empty.

The IEA's Global Critical Minerals Outlook 2025 found that expected mined supply from announced projects falls short of projected demand in 2035, with an implied deficit of 30% for copper under current policy settings. Without significant new investment, primary mined supply could increase from 23 million metric tons in 2025 to a peak of 27 million in 2030, then decline to 22 million by 2040.

Supply chain concentration adds a geopolitical dimension to the structural constraint. China controls 45% of global copper refining capacity and is projected to increase its share to 50% by 2040. The top three mining countries account for 46% of production, creating potential supply chain vulnerabilities as geopolitical tensions persist.

The consequence is a projected supply deficit of significant and growing magnitude. The looming deficit is forecast to reach 10 million metric tons — equivalent to almost one-third of current global demand — by 2040, in the absence of a meaningful expansion of supply. The IEA estimates that the industry needs between $500 billion and $800 billion of investment by 2040 to keep pace with demand under various scenarios.

What This Means for Copper Prices

Structural supply deficits of this scale translate into a sustained higher-price environment, with volatility amplified by the fact that copper has increasingly become a financial instrument as well as an industrial commodity.

For decades, the price of copper was a reliable barometer of global industrial health — an economic indicator so trusted it earned the nickname "Dr. Copper." That reality is gone. The current landscape is defined by a profound and structural shift: unprecedented, non-negotiable demand growth colliding with an inelastic, geologically constrained supply, amplified by the pressures of global financial markets. The volume of "paper copper" — futures contracts, options, and ETFs — often dwarfs the volume of physical copper being consumed.

Copper prices witnessed an exceptional rally through 2025, reaching a record high of over USD 12,000/MT, rising more than 30–35% over the year — the strongest annual increase since 2009. Unlike previous price spikes driven by cyclical recovery or speculative positioning, the 2025 rally was underpinned by structural demand strength and tightening physical fundamentals.

Analysts expect copper prices to average around $10,500 per ton in 2026, with upside potential if mine or smelter issues persist. Forecasts from major banks cluster in the $10,000–$11,000 range for the next two years. In all scenarios, prices are expected to remain elevated compared with historical averages.

The transformer sector has already absorbed these cost increases directly. Copper and grain-oriented silicon steel together account for over 50% of a power transformer's material cost. Since 2020, copper prices have risen by over 70%, while electrical steel prices nearly doubled. As a result, the global transformer industry still faces a 2–3 year manufacturing backlog, meaning price pressure is unlikely to ease before 2027.

What Industrial Buyers Should Do Now

For procurement teams and engineering organizations that depend on copper — whether for bus bar, switchgear components, transformer windings, coil, or pipe — the macroeconomic picture above translates into a specific set of operational imperatives.

Extend Your Planning Horizon

The era of 30- or 60-day copper procurement is over for any buyer with significant volume. Navigating this environment requires moving beyond simple purchasing and embracing a holistic strategy that integrates design, sourcing, and financial hedging. Blanket purchase orders against negotiated allocations, held by a qualified supplier, are the instrument that protects you from both spot price volatility and supply availability risk.

Treat Supplier Qualification as a Strategic Activity

In a structurally tight market, the difference between a copper supplier who can reliably deliver on a production schedule and one who cannot is a difference measured in project delays and schedule compression downstream. Qualification criteria should include certified supply chain documentation, direct mill relationships, and a demonstrated track record of on-time delivery through periods of market tightness. A DFARS-registered, ISO 9001-certified, AS9100D supplier — the credentials Maverick Metals carries — provides a baseline of supply chain hygiene that matters increasingly in a tighter market.

Lock in Prices on Forward Volume

Proactive hedging is critical. By employing a mix of futures, options, swaps, and smart contract terms, procurement teams can lock in most of their costs and avoid budget-busting surprises — providing price predictability and protecting margins. Even if your organization does not trade commodity futures directly, a supplier who can offer fixed-price commitments on forward volume delivers equivalent protection at the product level.

Rationalize Your Copper Specifications

In a tight supply environment, non-standard dimensions, non-stocked grades, and low-volume custom cuts become increasingly difficult to source quickly. Rationalizing your cut list to standard grades (C110 for the majority of bus bar applications, C101 where furnace brazing is involved) and standard dimensions reduces lead time exposure and improves your negotiating position on volume.

Build Recycled Copper Into Your Supply Strategy

Enhancing critical minerals recycling offers substantial financial and sustainability benefits, reducing mining investment needs by around 30% through 2040. Recycled energy transition minerals incur on average 80% less greenhouse gas emissions than primary materials produced from mining. For applications where recycled copper can be certified to the same purity and conductivity standards as primary material — with appropriate MTRs — it is worth developing supplier relationships that can access this secondary supply stream.

Integrate Copper Cost Scenarios Into Capital Project Planning

For manufacturers, utilities, and governments, the lesson is clear: plan for a world where copper is expensive, strategic, and volatile. Budgeting models should allow for price swings of $1,000 per ton or more, while procurement teams should align hedging instruments with actual delivery points to minimize basis risk between exchanges. Capital projects specified at one copper price point and procured at another will consistently underperform budget unless the planning process explicitly models price ranges and includes contingency accordingly.

The Fundamental Reality for Industrial Buyers

Copper is not a commodity in the way it was even ten years ago. It has become a critical mineral — formally designated as such by the United States, the European Union, Japan, India, Canada, and China — because its physical properties make it the irreplaceable conductor of the electrified economy being built around us. Copper plays a pivotal role in the shift toward clean, carbon-free energy. Power grids and electric vehicles heavily depend on copper for efficient electricity transmission.

The demand vectors driving this designation are not theoretical. They are the transformer orders backed up 128 weeks at major manufacturers. They are the 20 million EV charging points projected by 2030. They are the offshore wind cables being planned along coastlines from the North Sea to the Gulf of Mexico. They are the hyperscale data centers consuming copper bus bar at rates that would have been unimaginable five years ago.

The supply constraints are equally real. A 17-year average timeline from mine discovery to production means that the copper deficit of 2040 is already structurally locked in based on the discovery pipeline — or lack thereof — of the past decade.

"The supply gap threatens to constrain technological advancement and economic growth as copper becomes increasingly essential for AI data centers, electric vehicles, renewable energy infrastructure, and defense systems." — S&P Global

For industrial buyers, the practical implication of all of this is not to panic, but to professionalize. Copper procurement that was managed reactively when the metal was abundant and cheap must now be managed proactively, with longer time horizons, stronger supplier relationships, tighter specifications, and a serious price risk management framework. The organizations that develop these capabilities now, before the full weight of the 2030s demand surge hits the market, will have a meaningful competitive advantage over those who treat copper as an afterthought until the supply chain forces them to pay attention.
