Educational Goals

The aim of the course is to ensure that the student (1) learns and acquires the reasons underlying the particular characteristics of the renewable energy sources; (2) understands the ways of a proper choice of the devices and of the technical and economic design (albeit preliminary) for the systems of energy conversion and of the production of electricity through the use of renewable energies.

Content

The course presents and discusses the main technologies for the conversion of the so-called "renewable energies": solar energy (direct, biomass, wind), geothermal energy. A brief discussion is also reserved to the forms considered less traditional: ocean waves, sea currents and tides, OTEC plants.
Wide part of the course is devoted to solar power (thermal, photovoltaic and thermal), even with a thorough analysis of the radiation availability at ground level and of the methods for its estimation. We discuss also the peculiarities of geothermal sources and of the systems that allow his exploitation for the production of electricity. The analysis of the use of wind turbines is accompanied also by a description of the methods of the assessment of the availability of the wind energy resource.
Where possible, space is also dedicated to the presentation and discussion of technical and economic analysis of typical conversion systems.

Methods of Provision

Conventional

Teaching Methods

The lectures will be delivered in the classroom using educational material (presentations, lecture notes, fact sheets) made available, from time to time, by the teacher to the students . The lessons will always be accompanied by numerical applications related to concrete cases and during the year we will try to do at least a technical visit.
Where possible, the students will be directly involved in the solution of some significant problems: carrying out appropriate exercises in the classroom, as short lab reports.

Assessment Methods

Learning occurs through the direct involvement of students in the solution of problems and exercises during the lessons. . At the end of the course the student will take an oral examination.
