Statistics show that from 2005 to 2019, 66.3% of China''s total energy consumption came from highly polluting coal. Coal is cheap, but it has a well-known drawback that its carbon emission intensity is the highest.

China's structure change in energy consumption. Among China's solar capacity at the end of 2017, stationary solar capacity was 100 GW, while distributive solar capacity was only 30 GW . It is controversial to the original policy target of the Chinese central government.
Thus, the amount of solar radiation reaching the ground is relatively small. Furthermore, there is more land in the north, and the overall climate is dry, leading to strong solar radiation in general. Fig. 3. Spatial distribution of annual I g in China.
It is great merit to alleviate the geographic imbalance in China's energy endowment. According to the prediction of IEA, Fig. 2 shows that by 2040, the installed capacity of solar photovoltaics is expected to exceed wind, accounting for 22% of China's total electricity capacities. It indicates the great potential of China's solar power market.
