The "coal-based" Chinese energy structure will usher in a turning point in 2030.
"Although this is a forecast, it is likely to be achieved." Du Xiangxi said that the energy structure that coal will empty will be replaced by renewable energy such as hydro, nuclear, wind, and solar energy, and coal will also be overwhelmed by energy. "Abdicated as "important basic energy."
At the forum on the same day, Du Xiangxi also stated that nuclear power will play an important role in the future energy structure. By 2020, the installed nuclear power capacity will reach 70 million KW, and the power generation capacity will account for 7% of the national power structure.
Although the government has stated on many occasions that China will “substantially increase†the proportion of nuclear power, its plan for rejuvenating new energy still “has not come out for a long timeâ€. If the proportion mentioned by Du Xiangxie is finally realized, it means that China’s nuclear power will increase its target (4%) by 75%, which is “a substantial increaseâ€.

Coal will be relegated from "overwhelming energy" to "important basic energy"
On the morning of October 30th, Vice President of the Chinese Academy of Engineering Du Xiangyu expressed at the 2009 China Energy Enterprise High-Level Forum that China will usher in peak coal consumption by 2030. After that, China’s coal consumption will decline year by year, and by 2050, it will currently account for China’s primary energy. 70% of coal consumption will drop to about 40%.
