Solar panels are key to Biden's energy plan. But the global supply chain may rely on forced labor from China

New report alleges parts of China's solar panel supply chain rely on forced Uyghur labor and dirty coal.

But new research suggests that much of that work could rely on the exploitation of the region's Uyghur population and other ethnic and religious minorities, potentially tainting a significant portion of the global supply chain for a renewable energy source critical to combating the climate crisis. The report published Friday — titled "In Broad Daylight: Uyghur Forced Labor and the Solar Supply Chain" — presents evidence of a troubling reality: that components for clean energy may be created with dirty coal and forced labor. An advance copy of the report was shared exclusively with CNN Business.
