In response to the rapid expansion that characterizes the renewable energy sector, the course aims to provide a general overview of the main energy sources and some of the technologies, both commercial and under development, that can be employed for their correct use. In the first part of the course the structure of the national energy system and the incentive schemes for the production of energy from renewable sources will be analysed. Synergies and contrasts between Energy, Environment and Development will be evaluated. In the second part of the course, the basic knowledge related to the principles of operation and the performance of wind farms, hydroelectric, solar, biomass and geothermal plants will be provided.

The course includes 48 hours of theoretical lessons and 12 hours of plant design in the computer lab. During the practical exercises the theoretical principles studied in class will be developed with numerical application examples. Technical visits are scheduled to the renewable energy production plants. A practical application about innovative green energy resources will be developed within a team-project (max 4 students) during the course period.
