China is the leading global supplier of clean energy technologies today and a net exporter for many of them. China holds at least 60% of the world’s manufacturing capacity for most mass-manufactured technologies (e.g. solar PV, wind systems and batteries), and 40% of electrolyser manufacturing. Europe is generally a net importer, except for wind turbine components; about one-quarter of electric cars and batteries, and nearly all solar PV modules and fuel cells are imported, mostly from China. For solar PV, China supplies equipment directly to all markets except North America. The United States imports two-thirds of its PV modules, primarily from Southeast Asia, where Chinese companies have been actively investing.
