Skyrocketing prices of natural gas and coal are a new feature of the current global energy crisis，which implies a change in the source of energy security risks: climate change and energy transition are replacing geopolitics as a more important and lasting factor affecting energy security, although the latter is still an important factor affecting energy security. This paper analyzes the shift in the theory "logic" of energy security to adapt to new changes in energy security risks, that is, from energy supply security to energy system resilience, and analyzes the potential safety hazards in China’s energy system based on the logic of energy system resilience. A new idea of China’s energy security strategy under the new logic is proposed.
