Energy Security and Energy Transition: Towards Sustainable Energy Systems—Second Edition

Dear Colleagues,

As the global energy landscape continues to evolve in response to climate challenges, geopolitical shifts, and growing sustainability imperatives, the balance between energy security and the transition to sustainable energy systems remains a critical issue.

This Special Issue invites original research and reviews that examine how energy security can be maintained or even strengthened while accelerating the shift towards cleaner, more resilient, and equitable energy systems. We aim to bring together diverse perspectives, methodologies, and case studies that illuminate the pathways to a secure and sustainable energy future.

We welcome contributions addressing (but not limited to) the following topics:

• Strategies and policies to enhance energy security during the energy transition;
• Integration of renewable energy sources into existing infrastructure;
• Energy access and equity in the context of sustainability and security;
• Energy efficiency as a tool for strengthening energy resilience;
• Technological innovations, including smart grids, storage, and digital solutions;
• Governance, regulation, and institutional frameworks supporting secure transitions;
• Interlinkages between energy transition, security, and climate mitigation;
• Real-world examples and best practices demonstrating effective approaches.

We look forward to your contributions in relation to this impactful discussion.
