Copper, Carbon, and the Material Limits of the Energy Transition

Following my earlier note on copper demand and AI-driven electricity growth: https://substack.com/@meanmatch/note/c-173051895 and on commodities on the verge of a new supercycle: https://meanmatch.beehiiv.com/p/commodities-on-the-verge-of-a-new-supercycle

While copper demand is accelerating, the broader materials challenge of the energy transition is even more staggering in scope.

According to new research from the Geological Survey of Finland, phasing out fossil fuels globally would require over six billion tonnes of metals just to build a single generation of renewable infrastructure - wind, solar, batteries, and electric vehicles. That means replicating, within two decades, what humanity used to mine over millennia. Over the last 5,000 years we have extracted roughly 700 million tonnes of copper. Meeting the needs of the energy transition will require mining the same volume again by 2046.

And copper is not alone.

The study finds that even if every known mine operated at full capacity, global reserves and resources of copper, lithium, nickel, cobalt, graphite, and vanadium would still be insufficient to build one complete, fossil-free system. Recycling cannot fill the gap: the total amount of metal mined between 1990 and 2023 would cover only a fraction of what is needed for the first generation of renewable technologies.

If we relied on current extraction rates, it would take nearly 10,000 years to mine the lithium required for just one round of global electrification. The scale of what must be built is immense.

Replacing all fossil-fuel energy would require roughly 800,000 new power plants - including more than 1.3 million wind turbines and over 37 billion solar panels.

Wind and solar would need to generate almost 49,000 TWh of additional electricity annually, with massive battery banks acting as buffers to manage intermittency.

But the studies agree: even this model faces hard physical limits. The metals needed for such vast stationary storage, especially lithium, copper, and nickel, simply do not exist in sufficient, accessible quantities.

Battery technology, as currently envisioned, cannot scale to support a fully renewable grid.

The S&P Global report underscores the same conclusion from a different angle. It projects that global copper demand will double from 25 to 50 million tonnes per year by 2035, driven by electric vehicles, renewables, and grid expansion. Even under its most optimistic “High Ambition Scenario,” supply will fail to keep up, resulting in a deficit of 1.6 to 9.9 million tonnes per year through the 2030s.

By 2035, half of all copper demand will come from clean energy applications, while traditional uses in construction, manufacturing, and electronics continue to grow.
This means a record-high total demand of more than 53 million tonnes annually by 2050, sustained for decades.

The report warns that such shortages could become a systemic risk to the global economy - a “21st-century scramble for copper” reminiscent of the oil crises of the 20th century, but amplified by the higher geographic concentration of copper reserves and refining.

China currently dominates every stage of the copper value chain: it controls 42% of global refining capacity, 47% of smelting, and 54% of copper consumption, making it the epicenter of the copper economy. The United States, by contrast, could import up to two-thirds of its refined copper by 2035, even under accelerated mining and recycling scenarios. Adding to the challenge are long project timelines and permitting hurdles.

Developing a new large-scale mine typically takes 15 to 20 years, requiring billions of dollars in capital and stable regulatory frameworks - conditions that are not easily replicated at scale.

Copper ore quality is also declining: average grades have fallen from 5–10% a century ago to below 1% today, meaning ever more rock must be processed for every tonne of metal - increasing energy demand, water use, and waste output.

In short, the energy transition is colliding with the physical, geological, and geopolitical limits of the material world.

Even assuming record-high recycling and utilization rates, the supply gap remains too wide to close within the next two decades.

The path forward demands technological breakthroughs in extraction and substitution, faster permitting, and circular supply chains that turn today’s waste into tomorrow’s resource. Without these, the transition to clean energy risks being constrained not by carbon, but by copper.

For investors and policymakers alike, the copper gap is a signal: the transition to net zero will require rethinking resource governance, mining finance, and recycling economics on an unprecedented level. Energy security in the 21st century may depend less on hydrocarbons and more on the metals that move electrons.
