Research Hotspots and Trend Analysis of Energy Security Based on Citespace Knowledge Graph

Energy security is related to national economic development and social stability, and it is one of the significant and urgent problems faced by all countries in the world. This paper takes 36583 articles on energy security from 2013 to 2023 in the Web of Science database as the data set, using the CiteSpace Knowledge graph method to systematically analyze the status quo, research hotspots, and evolution trends of world energy security research. The results show that research hotspots are concentrated in six primary areas: energy governance, energy and climate change, renewable energy security, energy models, energy efficiency, and energy technology. The cross-research between artificial intelligence, communication technologies, and the field of energy security is one of the future research hotspots. Cross-disciplinary integration is an essential feature of research in energy security in recent years, which can provide reference for subsequent research.
