Special Issue Information

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.

This paper addresses the very important and topical issue of the effective and efficient implementation of green and energy transition processes, taking into account social aspects and energy security. Due to climate change and the geopolitical situation, these processes are currently priorities for most countries and regions of the world. The opportunity to achieve success in their implementation lies in the implementation of the Open Innovation concept in a new model developed and presented in this paper. Its essence is an identified group of stakeholders in the processes under study (science, business, state, society, environment) and their specific positions, roles, and relationships. It was also important to analyze the mechanisms of cooperation and interaction between stakeholders, defining key forms and directions, as well as ways of harmonizing them, leading to synergy in innovation processes. A significant stage of the work was also the development of a RACI role and responsibility matrix, which enabled the precise assignment of functions to individual stakeholders in the developed model. Key challenges, barriers (technological, regulatory, organizational, and social), and factors conducive to the coordination of cooperation and interests of the identified stakeholder groups were also identified. To deepen knowledge and better understand the dynamics of this cooperation, a matrix was also developed to assess priorities and their impact on the energy sector within the open innovation model. This tool enables the identification of diverse perspectives in relation to key criteria such as energy security, innovation, social participation, and sustainable development. In addition, a set of indicators (in five key categories of the innovation ecosystem) was developed to enable multidimensional measurement of the effectiveness, efficiency, and scalability of the open innovation model in the energy sector. They also allow for the study of the impact of these factors on the sustainable development, security, and resilience of energy systems. The developed and presented concept of a model of cooperation between stakeholders using the Open Innovation model in the energy industry is universal in nature and can also be used in other sectors. Its application offers broad opportunities to support the management of transformation processes, taking into account the innovative solutions that are necessary for the success of these processes.

In the current geopolitical context, sustainable energy development has become one of the pillars of global economic growth. This issue is well recognized in the European Union, which has undertaken a number of measures to achieve sustainable development goals. For these measures to be effective, it is essential to conduct a reliable, multi-variant diagnosis of the state of energy development in the EU-27 countries. This paper addresses this highly topical and important issue. It presents a new proprietary method—the Entropy–Evolutionary Evaluation of Sustainability (E3)—based on a multidimensional approach to researching and evaluating the state of sustainable energy development in the EU-27 countries between 2014 and 2023. Through the integration of 19 indicators representing the adopted dimensions of the study (energy, economic, environmental, and social), the method enabled both a static assessment and a dynamic analysis of energy transition processes across space and time. To determine the weights of the indicators for each dimension of sustainable energy development, the CRITIC, Entropy, and equal weight methods, along with the Laplace criterion, were applied. The Analytic Hierarchy Process method was used to establish the weights of the dimensions themselves. An important component of the approach was the inclusion of scenario studies, which made it possible to assess sustainable energy development under five variants: baseline, level, equilibrium, transformational, and neutral. These scenarios were based on different weight values assigned to three factors: the level of energy development (L), its stability (S), and the trajectory of change (T~). The results, expressed in the form of a total index value and dimensional indices, reveal significant diversity among the EU-27 countries in terms of sustainable energy development. Sweden, Finland, Denmark, Latvia, and Austria achieved the best results, while Cyprus, Malta, Ireland, and Luxembourg—countries heavily dependent on energy imports, with limited diversification of their energy mix and high energy costs—performed the worst. The developed method and the results obtained should serve as a valuable source of knowledge to support decision-making and the formulation of strategies concerning the pace and direction of actions related to the energy transition.
