In recent years, the level of energy efficiency in our country has been rising continuously, the energy and electricity consumption per unit of GDP have shown a downward trend. However, the two are not of the same frequency. The energy consumption has shown a continuous downward trend, while the electricity consumption has shown a downward trend of fluctuation, and the energy efficiency level of each province varies greatly. Firstly, the important policies and regulations of promoting energy efficiency in our country are sorted, the development of energy consumption and power consumption per unit of GDP in China and its provinces is analyzed , and the influencing factors of energy and power consumption per unit of GDP trend from different dimensions are analyzed. Then, the trend of several main factors affecting energy efficiency is analyzed, and the energy efficiency during the 14th five-year plan period is forecasted. The energy and power consumption per unit of GDP is expected to show a decline. Finally, some suggestions are put forward to increase the energy efficiency, such as promoting the electric-centered integrated energy system.
