Energy Security in Security Studies: A Systematic Review of Twenty Years of Literature

Abstract

Energy security has clear relationships with national security – historically, semantically, and practically. This exploratory study offers a quantitative and qualitative content analysis of 43 academic articles focused on energy issues, published in five international security studies journals – International Security, Security Dialogue, Security Studies, Contemporary Security Policy and Survival – from 2001 to 2020. The study identifies the main energy themes covered in the articles and the authors’ demographics. The paper concludes that the coverage of energy issues has been quite sporadic and largely underexplored in security studies. The essence of the debates over energy issues has not changed much since the energy crises of the 1970s – it remains predominately state- and Western-centric with a primary focus on oil and nuclear power. The crude oil price surge because of supply disruptions from the Middle East is still viewed as a main threat to energy security. Similarly, international armed conflicts, domestic instability and nuclear proliferation are prioritised among the most critical outcomes of energy insecurity. The primary public policy responses to threats to energy security still focus on foreign policy, diversification of suppliers and energy sources, domestic energy efficiency and strategic energy stockpiles.
