This specialization aims to introduce mechanical engineering students to a comprehensive and global view of the energy issue in today’s world. The discipline is given a complete coverage, first by studying energy production and conversion techniques (thermal machinery, nuclear energy, renewable energies), then via the analysis of risks related to energy production and means to reduce them (major risks, pollution), and finally by a study of the issues and consequences of energy consumption. This training, which includes all requisite theoretical and technological components, is further completed by laboratory work and factory visits.
