Abstract: The “14th Five-year Plan” period will be another major historical transition period for China's energy development.“Clean, low-carbon, safe and efficient” will be the distinctive theme of energy development and transformation. Governments and departments at all levels will increase the priority of energy system transformation. Various types of funds flowing into the energy transition field will increase significantly. Smart energy industry will become an important economic growth point and support the transformation of the energy system. The scale and proportion of non-fossil energy will increase substantially, the demand for fossil energy is expected to approach its peak, industrial energy consumption will begin to decline gradually, and the electrification will reach a higher level. It is estimated that by 2025, the total national energy demand will be close to 5.5 billion tons of coal equivalent, and the energy consumption per unit of GDP will drop by 16%~17%. The tremendous development of renewable energy, cross-province and cross-regional power trading, and international energy construction cooperation will support the formation of a new development pattern, which will be jointly promoted by domestic-oriented circulation, as well as domestic and international mutual circulation.
