Chinese President Xi Jinping announced at the 2020 Climate Ambition Summit that China plans to have 1,200 GW of combined solar and wind energy capacity by 2030.
China has already made major commitments to transitioning its energy systems towards renewables, especially power generation from solar, wind and hydro sources. However, there are many unknowns about the future of solar energy in China, including its cost, technical feasibility and grid compatibility in the coming decades.
Since the Hu Jintao regime, and highlighted further under Xi Jinping, China has sought to transform its economy through the huge investment in innovative technology. What is unique about solar energy in China is that it was an important export industry in the early 2000s, before it emerged as a critical renewable energy industry.
Most of China's solar power is generated within its western provinces and is transferred to other regions of the country. In 2011, China owned the largest solar power plant in the world at the time, the Huanghe Hydropower Golmud Solar Park, which had a photovoltaic capacity of 200 MW.
As such, critics argue that investments into renewable energy sources such as solar power are means to increase the power of the central state rather than protect the environment. This argument has been complemented by China's expansion of fossil fuel plants in conjunction with solar energy.
Since China is responsible for 80% of the world's polysilicon production, with half of the world's polysilicon produced in Xinjiang, many critics of the forced labor usage have stated that it is difficult for many countries to avoid Chinese made solar power solutions.
