The mayor of Sant Cugat said once “the best sensor is the citizen itself” and we could not agree more. That is the reason why this “truth” has become an obligatory reference for all the people who is involved in the Smart Cities revolution. Without citizens, nothing would be possible.
Hence, this fourth edition of SC Actual Smart City is mainly dedicated to explain how to implement all the latest innovations in our lives, so we can improve our life quality. Moreover, we are proud to announce that we have very interesting collaborations in this issue: one is the interview to the director of New and renewable sources of energy, energy efficiency and innovation in European Commission, Marie Donelly and the other one is the interesting article of the professor of Management at the Department of Business Administration at Carlos III University of Madrid, María José Alvárez Gil.
