EU Clean-Tech Manufacturing Dependency

01 / Clean Energy Component Manufacturing

Solar at 95%, batteries at 87%. EU policy mandates the transition; EU industry does not manufacture it.

The European energy transition depends on components that European industry largely does not manufacture. Solar panels and batteries — the two technologies at the centre of EU climate policy — are overwhelmingly imported from China. Europe ceded solar manufacturing to China between 2010 and 2020, drawn by lower costs and accelerated by a WTO dispute that ended EU anti-dumping tariffs. Batteries followed the same path. The US Inflation Reduction Act (2022) accelerated the shift further by pulling clean-tech investment to America with direct production subsidies. The EU's Net Zero Industry Act (2024) sets domestic manufacturing targets — 40% of annual deployment needs made in EU by 2030 — but the gap between those targets and current capacity is measured in hundreds of billions of euros and years of lead time. Wind turbines are the exception: EU manufacturers supply ~75% of domestically installed capacity, though financial pressure on all four major producers threatens that position.

Solar PV

Solar panels · rooftop + utility — Europe produced ~25% of global solar panels in 2010. By 2025, China controls ~85% through sustained state investment, vertically integrated supply chains from polysilicon to finished modules, and panel prices that fell ~90% over 15 years. EU anti-dumping tariffs existed from 2013 to 2018 but failed to sustain domestic manufacturers; once lifted, the remaining EU producers largely exited. Much of the SE Asia share represents Chinese-owned factories in Vietnam and Malaysia operating to circumvent trade measures.

Battery cells

EVs · grid storage — Korean manufacturers — LG Energy Solution, Samsung SDI, SK On — remain significant EU suppliers, and EU gigafactories (Northvolt in Sweden, ACC in France, others) are scaling from a near-zero base. China's CATL, the world's largest cell manufacturer, is building plants in Hungary and Germany. This improves supply proximity but raises questions about strategic ownership of critical infrastructure. EU domestic cell production remains under 10% of demand.

Inverters

Solar · battery · grid conversion — Inverters convert DC output from solar panels and batteries to AC for grid connection — a component in every solar installation and grid-scale storage system. Chinese manufacturers Huawei and Sungrow have captured roughly 60% of the EU solar inverter market through aggressive pricing. EU manufacturers SMA Solar (Germany) and Fronius (Austria) retain a shrinking share. Inverter market concentration closely tracks solar panel dependency.

Heat pumps

Building heating · cooling — EU manufacturers — Bosch, Vaillant, Viessmann, Daikin Europe, Atlantic Group — retain meaningful domestic market share, but Chinese brands (Midea, Gree, Haier) have rapidly gained ground with lower-cost units. Chinese import share grew from under 15% to roughly 40% within five years. EU heat pump installation targets under REPowerEU assume continued manufacturing capacity that is under structural cost pressure from Asian competition.

Wind turbines

Onshore + offshore wind — Wind is the EU's clean-tech manufacturing success story: Vestas, Siemens Gamesa, Nordex, and Enercon together supply ~75% of EU-installed turbines domestically. The threat is financial rather than geographic — all four major manufacturers posted significant losses in 2022–23 due to input cost inflation and power purchase agreements priced before the energy shock. Long-term supply capacity requires margins that the current market structure does not reliably deliver.
