The aim of the course is to provide students with the criteria for a quantitative assessment of the application of different technologies for the exploitation of renewable energy, in the industrial and civil fields. D1 - Knowledge and understanding The student, at the end of the course, will have to know the basic principles of operation of systems for the exploitation of renewable energy. D2 - Ability to apply knowledge and understanding The student must be able to carry out a preliminary quantitative assessment of the application of different technologies for the exploitation of renewable energy, to evaluate the possible contribution of renewable energy to the demand of production and residential sites, to calculate the indices of investment in technologies renewable. D3 - Autonomy of judgment The student must be able to evaluate the characteristics, advantages and drowbacks of the main technologies for the exploitation of renewable energies. D4 - Communication skills The student must be able to properly describe the various phases of the assessment regarding the application of different technologies for the exploitation of renewable energy, highlighting the physical basis of the assessment and the economic and environmental benefits of the intervention. D5 - Learning skills The student must be able to interpret and use the learned technologies and methodologies in the industrial and civil fields, also with reference to concrete cases other than those directly addressed in the course.
