As energy security has been an increasingly hot topic in research, a reliable and sound framework for allaying energy security is necessary. In this paper, it establishes a methodological framework based on quantitative and qualitative approaches for measuring and improving energy security from a broad sense. Firstly, it interprets the conceptual framework of energy security composed by seven dimensions, and 28 indicators are designed for its assessment. Then, Fuzzy AHP is used to indicate the importance of the dimensions and indicators, and the hybrid model of GRA-TOPSIS is introduced to evaluate energy security performance. Further, a qualitative root cause analysis is conducted with Why-Why Diagram to identify the possible causes affecting energy security. After that, a case study is conducted to investigate energy security of Henan province in China within the period of 2005–2017. The results indicate that, energy security is no longer a single-dimensional concept, but a synthetic term, and the technological, environmental, social, even political aspects can be improved to enhance energy security. The methodological framework with quantitative and qualitative techniques can help achieve an all-around understanding of energy security.
