China Dominates Global Clean Energy Supply Chains
Concentrated production capacity in China leaves international electric vehicle output vulnerable to potential export halts.

Is it a risk for countries to rely heavily on one nation for energy supply chains?
China maintains a dominant share of global clean-energy supply chains, including 97% of anode active materials and 95% of photovoltaic wafer capacity. An IEA assessment indicates that a one-month disruption in Chinese battery exports would cause a $17 billion decline in electric-car production outside the country.
Why it matters
Global manufacturing relies heavily on concentrated capacity in China, creating significant bottlenecks for the electric vehicle and solar sectors. This dependence leaves international markets highly susceptible to supply chain shocks, particularly as demand continues to outpace non-Chinese production capabilities.
China holds an 80% share of the lithium-ion battery supply chain and an 85% share across the solar photovoltaic market. Factories outside China currently struggle to cover even one-quarter of demand at critical stages of these supply chains.
The players
International Energy Agency
This intergovernmental organization provides analysis and policy recommendations to ensure global energy security.
The details
Nearly two-thirds of the projected $17 billion in electric-vehicle production losses would impact the European Union. The assessment confirms that even where final assembly exists elsewhere, local plants lack the necessary inputs to maintain operations during a Chinese export interruption.
Timeline
The International Energy Agency published the assessment on March 26, 2026.
Data for the assessment reflects 2024 benchmarks.
Supply-chain security is expected to remain constrained through the end of the decade.
Roadmap
This concentration of manufacturing power presents a major hurdle for the global transition to sustainable transport as nations aim to scale up electric vehicle fleets. It signals that Western automakers must significantly accelerate domestic input production to remain competitive against Chinese-dominated supply chains.
Consumers could face significant vehicle delivery delays and rising prices if global supply chains remain reliant on a single source for battery materials. These structural bottlenecks effectively limit the manufacturing capacity available to meet international demand for new electric models.
The takeaway
The heavy concentration of battery production in China highlights a critical vulnerability for the global automotive sector that will not easily be resolved this decade. Stakeholders should expect supply chain security and the localization of battery manufacturing to become central themes in future trade and energy policy discussions.
