Clean Energy Manufacturers

solar · wind · hydrogen

Clean generation equipment is overwhelmingly made in China. Outside thin-film solar and offshore wind, Western makers compete on tariffs and local content, not cost.

Top: China's share of global manufacturing capacity - polysilicon about 95%, wafers about 95%, solar modules about 80% and water electrolyzers about 60%. Bottom: leaders outside China - solar: First Solar, Qcells, T1 Energy and Waaree; wind: Vestas, Siemens Gamesa, GE Vernova and Nordex; hydrogen: Nel, thyssenkrupp nucera, Siemens Energy and Plug Power.

Finding

China makes most of the world's solar equipment and most wind turbines, and is scaling electrolyzers the same way

China holds about 95% of polysilicon and wafer capacity and about 80% of module capacity; LONGi, JinkoSolar, Trina, JA Solar and Tongwei lead every stage. Chinese turbine makers led by Goldwind and Envision supply most new wind capacity worldwide, and Chinese alkaline electrolyzers from LONGi Hydrogen and Peric sell at a fraction of Western prices.

Western manufacturing survives where technology or policy separates it from Chinese supply. First Solar's CdTe thin film uses no polysilicon and is the largest US module maker. Qcells built the first US ingot-to-module chain in Georgia, and T1 Energy took over Trina's Dallas module plant and is building a cell plant in Austin. In wind, Vestas, Siemens Gamesa and GE Vernova hold Europe and the Americas, helped by local-content rules and grid-security reviews of Chinese turbines.

Hydrogen is the least mature of the three. Western electrolyzer makers scaled back in 2025 as projects stalled, while China built the largest green-hydrogen plants with domestic alkaline stacks. Fuel cells have narrowed to niches: forklifts, buses and data center prime power, where Bloom Energy's solid oxide systems have found demand. See Green Hydrogen Electrolyzers.
