Abstract This chapter delves into Sustainable Development Goal 7 (SDG 7), which seeks to ensure access to affordable, reliable, sustainable, and modern energy for all. The chapter begins by contextualizing SDG 7 within the broader framework of the United Nations’ Sustainable Development Goals, emphasizing the vital role of energy in achieving economic growth, enhancing quality of life, and mitigating environmental impacts. It provides a detailed examination of the current global energy landscape, highlighting significant disparities in energy access and consumption patterns. Despite technological advancements and policy initiatives, numerous barriers continue to impede universal energy access. These challenges are categorized into financial, policy, technological, and socio-cultural barriers. The chapter provides a comprehensive analysis of these impediments, drawing on case studies and empirical evidence to underscore the complexity of achieving SDG 7. The chapter also presents a proposal for integrating renewable energy technologies at the Technical University of Civil Engineering Bucharest. This initiative aims to demonstrate the potential of educational institutions to contribute to the global energy transition. The proposal includes detailed plans for the implementation of solar panels, wind turbines, and biomass systems on campus, as well as the integration of clean energy topics into the curriculum. It highlights the importance of developing skills and competencies in students through hands-on projects and teamwork activities. Experimental results from the renewable energy initiative are presented and analyzed. The findings indicate significant improvements in energy efficiency and student engagement, with positive implications for policy and practice. The discussion interprets these results in the context of global energy challenges, identifying successes, limitations, and lessons learned. The chapter concludes with recommendations for future initiatives and research directions, emphasizing the potential for scaling up renewable energy projects and the critical role of educational institutions in promoting sustainable development.
