For more than a century, the global economy has been shaped by one basic reality: whoever could reliably access oil could influence energy, industry and geopolitics.
The clean-energy era is changing that equation.
Solar panels, wind turbines, batteries, electric vehicles and electricity networks are reducing our dependence on fossil fuels. But they are increasing our dependence on something else: critical minerals.
Lithium | Copper | Nickel | Cobalt | Graphite | Rare earth elements | Gallium | Germanium | Tellurium.
These materials are not fuels. We do not burn them to produce energy. But they are essential ingredients in many of the technologies needed to electrify the economy.
That creates a new strategic challenge. The question is no longer simply whether the world has enough clean-energy technology. It is whether we can build supply chains capable of delivering the materials behind that technology reliably, sustainably and affordably.
This is why critical minerals are increasingly being discussed as the “new oil” of the energy transition. The comparison is not perfect, but the underlying idea is useful: resource security is becoming supply-chain security. And that has major implications for companies far beyond the mining industry.
The clean-energy transition is also a materials transition
When we talk about decarbonisation, we often focus on electricity generation: more solar, more wind, more batteries and more electric vehicles.
But every transition has a physical foundation. A solar panel needs materials such as silicon, aluminium, silver and other specialised inputs. Wind turbines can require large quantities of steel, copper and, depending on the design, rare earth elements. Batteries rely on materials including lithium, graphite, nickel and cobalt.
This means that moving away from fossil fuels does not mean moving away from natural resources. It means changing which resources matter.
Research published in iScience in 2025 estimated that annual demand for critical minerals associated with low-carbon energy deployment could increase from about 4.7 million tonnes in 2022 to around 30 million tonnes by 2030, roughly a six-fold increase. The study also found that different clean-energy technologies can create very different mineral requirements, meaning the choice of technology itself can affect future supply constraints. [1]
Another 2025 study in Nature Communications similarly found that critical-mineral constraints could materially affect the scale and composition of future solar and wind deployment under climate-focused scenarios. [2]
In other words, the energy transition is not just an energy transition, it is a materials transition.
Why this becomes a supply-chain problem
At first glance, critical minerals look like a mining issue. But mining is only one part of the story.
A mineral extracted from the ground still needs to be processed, refined, converted into usable material, transported, manufactured into components, assembled into finished products and ultimately delivered to customers.
A disruption at almost any point can affect the entire chain. This is what makes critical minerals particularly important from a supply-chain perspective.
Consider cobalt. A 2025 study examining the global cobalt supply chain found that disruptions can propagate through interconnected upstream and downstream stages, creating cascading risks rather than isolated problems. [3]
That is familiar territory for supply-chain professionals. A shortage of one component does not always stay a shortage of one component. It can create production delays, price increases, inventory pressure and knock-on effects across multiple industries.
Critical minerals can amplify those effects because the supply base for some materials is geographically concentrated, while demand is increasingly global.
That creates a classic resilience challenge: What happens when a material that appears small in the total cost of a product becomes impossible to replace at short notice?
The biggest risk may not be scarcity; it may be concentration
“Do we have enough minerals?” is an important question.
But it is not the only one. A more useful question for supply-chain leaders is:
How concentrated is the supply?
A mineral can exist in large quantities in the Earth's crust and still be strategically vulnerable if extraction, processing or refining capacity is concentrated in a small number of countries or companies.
This distinction matters because supply-chain resilience depends not just on geological abundance, but on the ability to access, process and move material when conditions change.
Geopolitical tensions, export controls, trade restrictions, environmental regulation, infrastructure failures and sudden changes in demand can all affect availability.
Recent research on critical minerals increasingly treats resource security as a combination of geological, economic, technological and geopolitical factors rather than as a simple question of how much material exists underground. [3][4]
For businesses, this changes how supplier risk should be assessed. A supplier with a low unit price may not actually be a low-risk supplier. A geographically concentrated supply chain may be efficient in stable conditions but much more fragile when the operating environment changes. That is the central tension between efficiency and resilience.
The uncomfortable trade-off: resilience can make supply chains more expensive
For decades, supply-chain management has often focused on efficiency.
Consolidate suppliers. Reduce inventory. Standardise components. Buy at scale. Optimise transportation. These approaches can work extremely well when supply is predictable.
But resilience introduces a different question: What are we willing to pay to reduce the consequences of disruption?
For critical minerals, resilience may mean maintaining alternative suppliers, investing in additional processing capacity, redesigning products to use less scarce materials, increasing inventory buffers or developing recycling systems.
All of those choices can carry costs. This does not mean companies should abandon efficient global supply chains. In fact, recent research suggests the opposite.
A 2026 study of global solar photovoltaic supply chains found that international supply networks can generate substantial net energy benefits, while extreme tariff barriers could reduce those benefits by suppressing PV deployment. The study highlights an important point: globalisation itself is not necessarily the enemy of sustainability; poorly designed trade barriers can create new inefficiencies and environmental costs. [5]
The challenge, therefore, is not simply to “localise everything.” It is to build supply chains that combine global efficiency with strategic resilience.
Recycling could become the hidden reserve of the energy transition
There is another way to reduce dependence on primary mineral supply:
Stop treating used products as waste. Start treating them as resources.
This is where the circular economy becomes strategically important. Battery recycling is a particularly strong example.
A 2025 Nature Communications study found that industrial-scale lithium-ion battery recycling can reduce environmental impacts by at least 58% compared with conventional mining-based supply chains. The researchers also found that the electricity used during recycling is an important determinant of its environmental footprint. [6]
Another 2025 study modelled the future of battery recycling and found that high collection rates could play a significant role in reducing material scarcity. The authors estimated that a collection rate of at least 84% would be needed in their scenario to stabilise material supply by 2060. [7]
This is an important shift in thinking. Recycling is often discussed as an environmental responsibility.
For critical minerals, it is also becoming a supply-security strategy. The same logic applies beyond batteries. Solar panels, electronics, industrial equipment and other clean-energy infrastructure contain valuable materials that could eventually re-enter supply chains.
A 2024 perspective in ChemSusChem argues for moving from the concept of “critical raw materials” toward “circular raw materials”, combining material reduction, substitution, recovery and recycling with product design that makes circularity easier. [8]
The future supply chain may therefore have two sources: the mine and the material already in circulation.
But sustainability cannot stop at carbon
There is another reason the “new oil” comparison needs to be handled carefully.
Critical minerals are not automatically sustainable simply because they enable clean technologies.
Mining and processing can have environmental impacts. Water use, land disturbance, energy consumption and waste are real considerations.
There are social issues too. A 2024 Nature Communications study examining materials used in green-energy technologies found significant variation in social impacts across materials. It identified cobalt, lithium, silicon and zinc among the materials associated with higher social risks in the indicators examined. [9]
That creates a broader challenge for supply-chain managers. A supply chain cannot credibly call itself sustainable if it simply shifts environmental and social impacts upstream while focusing only on the emissions of the final product.
The clean-energy supply chain therefore needs to be assessed across three dimensions at once: environmental performance, supply resilience and social responsibility.
That is harder than optimising for cost alone. But it is also much closer to the reality companies now face.
So what should companies actually do?
The answer is not to predict the next crisis perfectly. No company can do that.
The better approach is to design supply chains that are less dependent on any single point of failure. That starts with visibility.
Companies need to understand where critical minerals enter their products and how far upstream those dependencies extend. A Tier 1 supplier may look diversified while several of its suppliers depend on the same processor, refinery or geographic region.
Second, companies should distinguish between price risk and availability risk. A material can be inexpensive today and still represent a major strategic exposure if there are few substitutes and limited alternative sources.
Third, resilience should be designed into product specifications. If engineers can achieve the same performance using less of a scarce material, or use a more widely available alternative, that can reduce supply-chain exposure before procurement even begins.
Fourth, recycling needs to be treated as part of supply strategy rather than as an end-of-life activity. That means designing products for recovery, building collection systems and establishing relationships with recyclers before large volumes of products reach retirement.
Finally, companies should measure resilience alongside sustainability. The traditional procurement dashboard might track cost, quality and delivery.
The next-generation dashboard may also need to ask:
Where are our critical-material dependencies?
How concentrated are they?
What can we substitute?
What can we recover?
And how quickly could we respond to a major disruption?
The real lesson: the clean-energy supply chain is being redesigned
The biggest mistake would be to interpret the rise of critical minerals as evidence that the clean-energy transition is fundamentally flawed.
The more useful interpretation is that the transition is exposing a new class of supply-chain challenges that must be actively managed.
Fossil-fuel supply chains were shaped around extraction, transportation, refining and combustion.
Clean-energy supply chains are shaped increasingly around minerals, advanced materials, manufacturing capacity, electricity infrastructure, technology choices and circular flows.
That is a very different system. And it requires a different mindset.
The winners in this environment will not necessarily be the companies that simply secure the cheapest materials.
They will be the companies that understand the full material lifecycle: where materials come from, how concentrated the supply is, how they are processed, what alternatives exist, how products can be redesigned, and how materials can eventually be recovered and put back into circulation.
That is what makes critical minerals so important. They are not just another category of raw material.
They sit at the intersection of energy security, industrial strategy, sustainability and supply-chain resilience. So, are critical minerals really the “new oil”? Not exactly.
But the comparison highlights an important lesson from the last century:
When a resource becomes essential to the functioning of the economy, the supply chain behind that resource becomes a strategic asset. The clean-energy era is now proving that lesson all over again.
