Historically, what counted as energy security hinged almost entirely on whether a nation could reliably obtain oil and gas supplies. Supply vulnerabilities tied to a narrow base of energy producers — concentrated in the Middle East and parts of Eastern Europe — were laid bare repeatedly by armed conflicts, disruptions to shipping lanes, and broader geopolitical friction, prompting administrations to seek out more diversified sourcing arrangements.

Debate is growing over whether the global push away from fossil fuels is simply trading one form of concentrated control for another.

Prior to the military offensive launched against Ukraine, gas shipments from Russia accounted for roughly 45 per cent of all natural gas brought into the European Union from abroad. With the onset of armed conflict, European nations moved to diversify their supply chains by pursuing energy and commodity options beyond their existing partnerships. Tensions over energy supply resurfaced across the Middle East, where unrest drew renewed attention to how heavily global fuel networks depend on a handful of chokepoint transport corridors.

Shifting away from conventional energy sources could limit a country's vulnerability to the supply bottlenecks that have historically disrupted those markets. Production and deployment of the tools powering that shift remain heavily concentrated in a handful of markets, with China holding an outsized share across broad stretches of the clean-energy supply chain.

Trade data place China among the top exporters of renewable energy equipment and clean-power technology at present. Shipments of green-energy products posted a 51 per cent year-on-year rise in July 2026, with new-energy vehicle exports recording a near-doubling at 90 per cent above the prior-year figure. The breadth of that expansion reflects how extensively China now underpins the flow of technology to other economies.

Across the full sweep of clean-energy manufacturing — from raw materials to finished components — that nation holds a presence at nearly every link in the chain. Solar panel manufacturing and lithium-ion battery production are two industries where a single country holds a commanding share — near 85 per cent and 80 per cent of worldwide output, respectively. Roughly 73 per cent of all electric vehicles manufactured globally during 2025 rolled off assembly lines located within China's borders.

Mineral processing and refining — covering the raw materials that go into batteries, wind turbines, and electric motors — represents another area where its market position carries considerable weight, according to available data. That contribution extends beyond finished goods to mineral processing, industrial know-how, and the manufacture of machinery and components. Pressure at any one point in that network of connected dependencies can ripple outward, affecting the broader renewable-power sector.

According to IEA projections, a 30-day halt in battery supply-chain shipments from China would drain roughly $17 billion from electric-vehicle assembly operations elsewhere in the world, with European manufacturers absorbing more than half of that shortfall. New controls on rare earth exports have put renewed attention on how concentrated the sourcing of materials across global supply networks has grown.

Two distinct stages of the rare earth supply chain — extraction of the raw materials and subsequent production of the permanent magnets built from them, both feeding into a broad array of advanced technologies — sit largely under Chinese control, with that country accounting for around 60 per cent of global mining output and close to 90 per cent of magnet manufacturing. Without ready substitutes on hand, producers face the prospect of their supply chains breaking down if a key input becomes unavailable.

Where oil reserves owe their existence to geological accident, the foothold that China has established in this sector traces back to deliberate choices around capital deployment, manufacturing capability, and state-directed industrial strategy. Competing firms technically hold the option to develop their own alternatives, though building replacement capacity takes both time and effort that cannot easily be compressed.

IEA data attributes more than two-fifths of the battery-price gap between Chinese and European producers to streamlined production processes and factory automation rather than raw-material or labour differences. Attention within that conversation has shifted toward the question of diversification.

Ventures pairing MP Materials with partners in Saudi Arabia and the United States point toward a broader geographic spread in rare-earth processing capacity. Moving away from fossil fuels without trading one form of external dependency for another stands as the defining policy puzzle of the energy shift.
