Chinese suppliers control about 90% of the US energy storage market, raising concerns about over-dependence on a strategic rival.

The energy storage market (batteries/battery storage) is a key factor for the development of solar and wind energy. The 90% concentration of supply from Chinese suppliers is directly linked to the US renewable energy supply chain, affecting costs, deployment speed, and strategic independence in clean energy technology. This concerns the clean industry (XLI - sustainable industry) because energy storage is a core component of renewable energy infrastructure.
