Energy security is constrained by internal and external factors such as the increasingly complex international situation, insufficient domestic reserve resources, and the difficulty of replacing traditional energy systems with new energy sources. With the support of policies, energy security should focus on energy security, efficient and clean use of traditional energy sources, and accelerated development of new energy sources. [2–5]. The policy should focus on energy security, efficient and clean use of traditional energy sources, and accelerated development of new energy sources [2–5].
