能源安全是国家安全体系的重要组成部分，受全球地缘政治、新型冠状病毒肺炎疫情蔓延的影响，我国能源安全面临严峻挑战。综合高效利用国内能源资源、控制和减少油气进口规模、保障能源安全，仍是我国高质量、可持续发展亟待研究的课题。本文梳理了能源安全概念的演变历程、国外代表性的能源安全战略，从“发展可持续、供应有保障、科技有支撑、经济可承受、体制有保障” 5 个维度研究界定了能源革命条件下我国能源安全的新内涵；在此基础上研判了我国能源安全面临的形势并提出相应战略构想。研究表明，稳定传统能源生产，保障进口油气供给安全，实施多能互补、提升可再生能源消费比重，提高能源科技水平、加快能源科技创新合作，完善能源发展体制机制，是我国能源发展的必要举措。最后从顶层设计与规划、天然气与可再生能源融合发展、新能源科技创新研发、能源对外合作深化等角度提出了对策建议。

Energy security is important for the security system of a country. Affected by global geopolitics and the COVID-19 pandemic, China’s energy security is currently facing severe challenges. Reducing the import scale of oil and gas based on the comprehensive and efficient utilization of domestic energy to ensure energy security remains a topic that requires research for promoting China’s high-quality and sustainable development. This study first reviews the evolution of the energy security concept and summarizes the energy security strategies of typical countries. Then the energy security in China is defined from five dimensions: sustainable development, guaranteed supply, scientific support, economic affordability, and guaranteed system. Moreover, the situation faced by China’s energy security is studied and corresponding strategies are proposed. We propose that China should make efforts to stabilize the production of traditional energies, ensure the supply of imported oil and gas, promote renewable energy consumption to complement the current energy mix, encourage cooperative innovation of energy science and technology, and improve the energy development mechanism. Furthermore, we propose several policy suggestions to ensure China’s energy security from the aspects of top-level plan, integrated development of gas and renewable energies, scientific innovation of renewable energies, and international cooperation.
