Windmills are made in China.

The claim 'Windmills are made in China' can be interpreted as stating that wind turbines (often colloquially called windmills) are manufactured in China. This is largely accurate. China hosts a large number of wind turbine manufacturers, over 40 active companies, and dominates the global market with approximately 60% market share in wind turbine manufacturing.en.wind-turbine-models.comen.wind-turbine-models.comWind turbines manufacturers from China

Chinese companies such as Goldwind, Envision, Mingyang, and Dongfang Electric Corporation produce some of the world's largest and most advanced turbines, including record-breaking offshore models. Additionally, China leads the world in installed wind power capacity and continues rapid expansion of wind energy infrastructure.reuters.comreuters.comExplainer: China's dominance in wind turbine manufacturing

However, it is important to note that while many turbines and components are made in China, wind turbines are also manufactured in other countries including Europe and the US. Furthermore, some components may be sourced internationally or assembled elsewhere. Thus, the claim is mostly true but simplified; it does not capture the full complexity of global supply chains and manufacturing distribution.

The evidence overwhelmingly supports that China is a major manufacturing hub for wind turbines today.
