One of the cornerstones of the Biden administration’s strategy to achieve net-zero emissions by 2050 is to fully decarbonize U.S. electricity generation by 2035. In 2023, renewables, including solar, wind and hydropower, accounted for about 25 percent of the electricity generated in America.
Closing that gap requires simultaneous progress in multiple areas, including streamlining and speeding interconnection and permitting, expanding transmission capacity, and building a large and skilled workforce. Importantly, it also demands a rapid and large-scale buildout of its domestic manufacturing capacity.
It would be impossible in just two years for the IRA-driven boom in domestic manufacturing to create a resilient supply chain able to fully meet America’s demand for clean energy products. In particular, the critical minerals, components, and manufacturing capacity for both solar and energy storage are concentrated overseas, mostly in China, which accounted for about three-quarters of all global investment in clean energy manufacturing in 2023, according to the International Energy Agency (IEA).
China’s dominance of clean energy manufacturing is well documented. A few data points illustrate the dominance China has across the solar and energy storage value chain:
In 2023, China produced almost 82 percent of the world’s solar modules and is expected to manufacture 80 percent of all modules by 2030.
China also produces over 90 percent of all polysilicon, cells, and wafers. According to the IEA, China’s share of polysilicon production increased from less than 60 percent five years ago to more than 90 percent today.
Similarly, China manufactured nearly 83 percent of all the batteries produced in 2023.
China produces 84 percent of the anode materials, including graphite, along with 63 percent of the cathodes and nearly 70 percent of the electrolytes used in lithium ion batteries.
