Europe's China Green Tech Reliance a Security Risk

A New Geopolitical Dependency

Europe’s accelerated push for renewable energy has created a critical dependency on Chinese green technology, sparking urgent warnings about new national security vulnerabilities. A recent report submitted to the UK government highlights the risk of exchanging reliance on Russian fossil fuels for a strategic dependence on Beijing’s manufacturing prowess.

This shift comes as nations seek energy independence following recent global energy shocks, particularly the market volatility caused by the war in Ukraine. However, this race toward sustainability is building a new supply chain dominated by a single state actor.

The Scale of Chinese Dominance

China's control over the green technology sector is immense. The country manufactures approximately 90% of the world's solar panels and around 80% of both wind turbines and battery cells, which are fundamental components for the energy transition.

This market power is not limited to finished products. Beijing also controls a significant portion of the global supply of vital raw materials and the processing capacity required to turn them into components for renewables, creating multiple potential choke points in the supply chain.

Analysts warn that European authorities are at risk of “sleepwalking” into a major security problem. The concentration of manufacturing and resource control in China presents a level of dependency that rivals previous exposure to singular fossil fuel suppliers.

National Security and Economic Risks

The security concerns outlined in the report are twofold. First is the possibility that Beijing could restrict exports of technology or raw materials as a form of geopolitical leverage, effectively holding Europe's climate goals and energy infrastructure hostage.

Second, and more direct, is the threat of disruptive attacks. With Chinese technology deeply embedded in Europe's critical energy grids, there is a risk of backdoors or malware that could be used to disable power systems during a diplomatic crisis or conflict.
