**Abstract:** The use of renewable energies and energy saving and e fficiency are needs of global society and universities. Universities have a large responsibility and social impact, as they are an example and engine of social change. Universities, in the European context, must be at the forefront of sustainability progress, seeking to be at the same level, and preferably higher than the rest of society, seeking the goal of 20% in renewable energy for 2020 and, in the longer term, greater energy e fficiency based on a diverse use of renewable energy and studying the feasibility of other energy processes (cogeneration, trigeneration, etc.). The application of renewable energies and efficiency allow universities to make significant savings in their costs and contribute to sustainable development and the fight against climate change. Actions on these aspects in addition to the objective of saving should seek to promote research and form an example for the university community. This Special Issue aims to advance the contribution of energy saving and the use of renewable energies in order to achieve more sustainable universities.
