China is currently facing from "high-carbon to low-carbon, low-carbon to carbon-free" two-legged parallel enormous pressure. The reason is that my country has not yet completed the primary energy transformation from high-carbon energy to low-carbon energy. At present, 60% of energy consumption is still coal, while other major countries in the world have completed the transformation from high-carbon to low-carbon. Therefore, at this stage, the transformation goal of other countries is to further increase the proportion of renewable energy and realize the transition from low-carbon to carbon-free, while my country must realize the transition from high-carbon to low-carbon, and at the same time realize the transition from low-carbon to carbon-free.

In this regard, it is necessary to control the total energy consumption, strictly control coal consumption through energy efficiency improvement, and optimize the energy structure. The ideal energy structure is non-fossil energy accounts for 50%, natural gas accounts for 20%-25%, oil and gas accounts for 35%, and coal only accounts for 10%-15%. As far as China's current energy structure is concerned, there is no doubt that there is a huge gap.

Under the huge pressure of my country's low-carbon energy transformation, my country's current energy structure optimization is still facing multiple challenges such as coal rebound, slow development of clean energy, and imperfect policy mechanisms.

The limited sustainable development capacity of clean energy is also one of the challenges for China to realize the optimization of energy structure. At present, many bottlenecks in my country's low-carbon energy development are not in technology, but in the system itself. At present, my country's energy investment return mechanism and benefit-sharing mechanism have problems, and reforms must be deepened at this stage.

In order to realize energy transformation and reduce the number of hours of coal power utilization, it is necessary to solve the problems of how to share the transformation cost, whether the transformation measures are in place, local financial sources and whether there are sufficient funds for the transformation training of young workers. In this regard, the formulation and implementation of China's energy policy should be considered in the framework of energy transition, and should be in line with the logic, direction and requirements of energy transition.
