This proceedings volume consists of peer-reviewed research papers from the 3^rd International Conference on Smart Grid Energy Systems and Control – SGESC 2025. It brings together cutting-edge research and innovative practices in the field of sustainable and renewable energy. It explores a wide spectrum of topics, including biofuels, bioenergy, thermal energy, and renewable energy systems for power and heat generation. The book delves into solar thermal and photovoltaic technologies, greening fossil fuels, solar desalination, hydrogen and fuel cells, and alternative fuels. The volume also covers waste-to-energy technologies, green energy applications in transportation, and their environmental impacts. The book also addresses energy harvesting from waste, sustainable energy in agriculture and food processing, and the role of green buildings in energy conservation. This volume serves as a valuable resource for researchers, engineers, policymakers, and practitioners working in the fields of renewable energy, environmental science, sustainable development, and smart infrastructure.
