The global energy crisis, exacerbated by the pandemic and Russia's invasion of Ukraine, has significantly impacted energy management, with natural gas and electricity prices reaching record highs. This has led to increased inflation, poverty, and economic slowdowns, but also accelerated the adoption of renewable energy sources. The crisis has highlighted the importance of energy efficiency (EE) and renewable energy investments. The paper reviews literature on EE, focusing on individual consumers and industries, and examines the complex relationship between energy awareness, consumption patterns, and EE. It emphasizes the role of industries in contributing to energy-saving efforts and the active role of consumers in the energy market. The study uses a systematic literature review method, analyzing publications from Scopus and Web of Science databases, to evaluate the impact of the global energy crisis on EE. The findings underscore the need for a comprehensive approach that integrates energy-saving criteria into product development and corporate social responsibility. The paper also discusses the concept of EE, its importance in industry and households, and the policy instruments used to improve EE, while addressing the barriers and limitations of these policies. Finally, it explores the concept of energy awareness and its role in promoting sustainable energy management and EE.The global energy crisis, exacerbated by the pandemic and Russia's invasion of Ukraine, has significantly impacted energy management, with natural gas and electricity prices reaching record highs.
