Mike Gallagher, former U.S. representative of Wisconsin's 8th Congressional District, expressed concerns about the United States' reliance on China-made batteries, solar panels, and related hardware. He suggested that this dependence could lead to hidden vulnerabilities in critical infrastructure. Gallagher made these remarks on X.

"Add in that China dominates the market for batteries, solar panels, and associated hardware like inverters," said Gallagher, Former U.S representative. "we are literally embedding potential backdoors into our critical infrastructure. on behalf of the CCP's soldiers and spies."

According to the International Energy Agency (IEA), China controls over 80% of the global manufacturing capacity across all key stages of the solar photovoltaic supply chain, including polysilicon, wafers, cells, and modules. The IEA executive summary indicates that this concentration has led most countries to rely on Chinese suppliers for solar panels and components such as inverters. The report highlights that these dependencies impact the structure and resilience of national energy systems where such hardware is used.

HRone, referencing data from BloombergNEF, reports that Chinese companies made significant investments in global clean technology manufacturing in 2024, especially in sectors like batteries and solar panels. According to BloombergNEF, China's share of the battery manufacturing market remains substantial, with companies like CATL expanding their presence both domestically and internationally. This trend results in a higher proportion of clean technology components being produced by Chinese firms for export worldwide.

The Financial Times notes that CATL and other Chinese battery manufacturers have been expanding their international operations with government support. This expansion is influencing the global battery supply chain's composition, particularly for electric vehicles and energy storage projects. The article also mentions discussions among officials and industry experts regarding the strategic implications of market concentration in the battery sector.

Gallagher is a distinguished fellow at the Hudson Institute and serves as head of defense at Palantir Technologies. He represented Wisconsin’s Eighth District in the U.S. House of Representatives from 2017 to 2024, where he chaired the Select Committee on Strategic Competition with the Chinese Communist Party and played a leading role in cybersecurity and national security policy. Before his time in Congress, Dr. Gallagher served as a Marine Corps intelligence officer and received multiple awards for his bipartisan leadership on national security issues.
