The International Energy Agency says China "has an outsize impact on solar and wind supply chains."
China accounted for about 70% of global solar-panel shipments in 2019.
China also has a significant share of global wind-turbine manufacturing and shipments. Six of the world's top 10 wind-turbine manufacturers in 2020 were Chinese-owned, according to global trade platform BizVibe. The largest manufacturer, Denmark-based Vestas, holds 16% of the world wind-turbine market. General Electric, the only U.S.-based supplier in the top 10, ranks 4th.
