Capacity can expand faster than independence from the systems that make that capacity possible.
Observation
Growth is usually visible through what a system gains: more production, more equipment, more connections, more throughput or more usable service. Dependency is visible through what the expanded system continues to require.
The two conditions can develop together. A system may become larger and more capable because specialized suppliers, external infrastructure, imported inputs, shared standards or international capital make expansion possible. If those enabling conditions become more important to continued operation, capacity has increased without producing equivalent independence.
This is not an argument against integration or specialization. Dependence can reflect efficiency, comparative advantage, accumulated expertise and scale economies. Nor does an external input establish dependency merely because it crosses a border. The relevant evidence concerns whether a required function can continue, be replaced or be shifted within the time and scale that the system needs.
Evidence Context
The evidence reviewed for this article covers three connected but distinct areas: AI-focused data centres, electric-vehicle batteries and refined critical minerals. The cases do not represent all forms of economic growth. They were selected because recent evidence measures both capacity expansion and the conditions on which that expansion relies.
Across these cases, the word capacity has different meanings. Data-centre electricity consumption indicates operating activity, not compute performance. Battery deployment measures installed energy capacity in vehicles, while nameplate manufacturing capacity measures the maximum stated output of factories. Refined-mineral supply measures processed material, not mining reserves. These metrics cannot be combined into one capacity total.
Dependency also differs by case. It may concern electricity and grid access, component supply, manufacturing concentration, technical expertise, refined materials or the time required to qualify an alternative. Concentration is evidence about structure. Dependency requires an additional link to operational need and substitution difficulty.
Structural Analysis
Growth Is Not Independence
A capacity increase answers the question of how much more a system can do. It does not answer who controls the inputs, whether alternatives are available, or how quickly a supplier can be replaced.
Installed assets may deepen reliance on an upstream layer if greater utilization requires more of a specialized component or service. A new battery factory can add nameplate manufacturing capacity while relying on imported active materials and external technical knowledge. A data centre can add computing infrastructure while depending on grid connection, transformers, advanced chips and high-bandwidth memory. An expanding mineral market can increase refined supply while concentrating most incremental output in one producing country.
These relationships do not establish vulnerability automatically. Dependency becomes operationally relevant when disruption, switching time, compatibility, qualification requirements, regulation or insufficient alternatives can affect usable capacity.
Access Is Not Control
A buyer may have reliable access to a concentrated supply chain without owning or controlling it. Long-term contracts, inventories, multiple commercial suppliers and established logistics may preserve access. Conversely, nominally diverse suppliers may depend on the same refinery, production technology, grid node or upstream material.
Ownership alone is also insufficient. A domestically owned facility may rely on imported equipment, software, feedstock or specialist maintenance. Foreign investment may expand local capacity without proving external control. The relevant question is which conditions must remain available for the operating function to continue.
Selected Evidence Cases
AI Data Centres: More Operating Activity, More Enabling Requirements
The International Energy Agency reported that global electricity demand from data centres grew by 17% in 2025, while electricity consumption by AI-focused data centres increased by 50%. The IEA also reported that capital expenditure by five large technology companies exceeded USD 400 billion in 2025. These observations show rapid expansion in operating activity and investment, although expenditure is not equivalent to completed capacity. [1]
The same evidence identifies the enabling layers. The IEA reported tighter supply chains for gas turbines, transformers, advanced chips and information-technology components. It also reported that the expanding project pipeline was straining planning and regulatory systems, holding up grid connections and other necessary approvals. A shortage of high-bandwidth memory, a component used in AI chip production, had also developed during the preceding six months. [1]
This supports a bounded conclusion: data-centre activity expanded while access to electricity, grid connections and specialized equipment became increasingly important to further expansion. It does not establish that every operating data centre was dependent on one provider, or that the global AI system had reached a single binding constraint.
The case also contains counter-evidence. Electricity used per AI task was falling rapidly, which can reduce the input required for a defined task even as total use rises. Technology companies accounted for around 40% of corporate renewable power-purchase agreements signed in 2025, while some developers pursued on-site generation. These responses can expand optionality, but a contract or proposed generator is not the same as immediately available electricity. [1]
EV Batteries: Deployment Expanded Through a Concentrated Industrial Base
Global EV battery deployment reached 1.2 terawatt-hours in 2025, almost 30% more than in 2024 and more than seven times the 2020 level. Global lithium-ion battery nameplate manufacturing capacity exceeded 4 terawatt-hours at the end of 2025, approximately 30% higher than one year earlier. These are two different measures: deployment records batteries entering use, while nameplate capacity describes factories. [2] [3]
The manufacturing foundation remained concentrated. China accounted for more than 80% of global battery-cell production and more than 80% of global nameplate manufacturing capacity in 2025. Companies headquartered in China, Korea and Japan supplied nearly all battery cells used worldwide. In the European Union, Chinese producers supplied more than half of EV battery deployment in 2025, almost twice their 2023 share. [2] [3]
The observed expansion therefore depended heavily on an industrial base concentrated in a small number of countries and companies. Yet concentration alone does not prove supply insecurity. The evidence becomes stronger where alternatives require long construction, ramp-up and qualification periods. The IEA noted that a battery plant can take more than five years after beginning operations to approach nominal output. It also found that production of lithium iron phosphate cathode materials and precursors remained almost entirely concentrated in China. [3]
Counter-evidence is material. Battery manufacturing capacity grew faster in the European Union and the United States than in China during 2025, at approximately 50% compared with slightly more than 25%. Capacity outside the three largest production regions almost doubled. More than 50 gigawatt-hours of United States battery capacity was reallocated toward lithium iron phosphate production. These changes indicate diversification and adaptation, although new nameplate capacity does not prove equivalent production volume or an independent upstream materials chain. [3]
Technology substitution also matters. Lithium iron phosphate batteries avoid cobalt, reducing exposure to cobalt supply conditions. Sodium-ion batteries offer another possible chemistry pathway that does not rely on lithium. Neither option is functionally identical for every use, so chemistry availability should not be treated as full substitutability. [3]
Critical-Mineral Refining: Supply Growth Became More Concentrated
Demand for key energy minerals continued to grow in 2025 as batteries, electricity grids, wind turbines, solar photovoltaic systems and permanent magnets expanded. The IEA reported that global battery demand grew by more than 35% to exceed 1.5 terawatt-hours, while demand for key energy minerals had grown by close to 10% per year on average in recent years. [4]
Refined supply also increased, but much of its growth came from the existing leading producers. Between 2023 and 2025, Indonesia for nickel and China for most other key energy minerals accounted for more than three-quarters of total refined-supply growth. In manganese, nickel and graphite, almost all incremental supply came from the leading supplier. Excluding rare earths, the average share held by the largest refining country rose from 70% in 2023 to 72% in 2025. [4] [5]
This is direct evidence of capacity growth and increasing concentration occurring together. The dependency interpretation requires more than those shares, however. Refined minerals must be connected to downstream operating needs, and replacement must be difficult within the relevant period.
The IEA documented an observed transmission in 2025. Export controls introduced by China in April on seven heavy rare-earth elements had significant effects across downstream industries, forcing some automakers to reduce utilization rates or temporarily halt operations. This provides direct evidence that concentrated supply became operationally relevant under disruption. [5]
Rare-earth refining provides counter-evidence to a universal concentration trend. New projects in the United States and higher production in Malaysia produced a modest decline in concentration between 2023 and 2025. The change did not eliminate dependence, but it demonstrated that targeted investment and new operating production can alter the structure. [4] [5]
Counter-Evidence
The reviewed evidence does not support a general rule that growth always deepens dependency. It supports a more conditional finding.
- Efficiency gains reduced the electricity required for individual AI tasks, even while aggregate data-centre electricity use increased. [1]
- Battery manufacturing capacity outside China grew faster from a smaller base, creating additional geographic options. [3]
- Battery chemistry changes reduced or removed reliance on particular minerals for some applications. [3]
- New rare-earth refining projects in the United States and increased Malaysian production modestly reduced concentration. [5]
These developments show that capacity can expand through diversification as well as concentration. They also show why announced projects and nameplate capacity must not be counted as usable alternatives until production, upstream inputs, technical performance and scale are demonstrated.
What the Evidence Does Not Establish
The evidence does not establish that globalization is inherently vulnerable, that imports are a strategic weakness, or that domestic ownership produces autonomy. It does not show that every dependency will be disrupted or that present concentration predicts a future crisis.
The evidence also does not establish full independence where diversification has begun. Additional factories may share upstream suppliers. Alternative technologies may involve different performance, infrastructure or cost conditions. A second source may exist but lack spare capacity at the scale required.
Finally, the cases cannot be collapsed into one global dependency measure. Electricity access, battery manufacturing and mineral refining operate through different systems, units and time horizons. Their common feature is structural: growth in the downstream function can occur faster than diversification of the enabling layers.
Closing Observation
The reviewed evidence supports the core line under defined boundaries: capacity can expand faster than independence from the systems that make that capacity possible.
AI data-centre activity expanded while grid access and specialized components became more consequential. EV battery deployment and manufacturing capacity grew while production remained concentrated within a small industrial base. Refined-mineral supply increased while much of the incremental output came from the existing leading suppliers.
None of these conditions makes dependency inherently negative. The strategic meaning depends on whether the required input remains accessible, replaceable and operationally usable within the time and scale the expanded system requires.
Growth should be examined not only by asking how much capacity was created, but also by asking what the expanded capacity requires in order to continue functioning.
Evidence Discipline
Evidence was reviewed through 2026-09-05. Observed 2025 activity, installed or nameplate capacity, reported constraints, announced projects and forecasts are kept separate. Data-centre electricity consumption is not treated as compute capacity. Battery deployment is not treated as manufacturing capacity. Nameplate manufacturing capacity is not treated as operational output. Refined supply is not treated as mineral reserves.
Concentration is not treated as dependency without evidence of operational reliance or substitution difficulty. Dependency is not treated as vulnerability without an observable transmission mechanism. Evidence from selected energy and technology systems is not generalized to all economic growth. Forecasts and conditional statements from sources are not presented as observed outcomes.
