Solar generation cannot be cut off by geopolitics once installed, unlike oil and gas, which contributes to energy security.

As of 2022 over 40% of global polysilicon manufacturing capacity is in Xinjiang in China, which raises concerns about human rights violations (Xinjiang internment camps).

According to the International Solar Energy Society China's dominance of manufacturing is not a problem, both because they estimate solar manufacturing cannot grow to more than 400b USD per year, and because if Chinese supply was cut off other countries would have years to create their own industry.
