Learning objectives
At the end of the course, the student:
- (D1) will know the fundamental concepts of energy, entropy and reversibility;
- (D2) will have the instruments to scientifically discuss about ecological transition and circular economy;
- (D3) will be able to judge in some autonomous way on the environmental sustainability of different types of energy technologies;
- (D4) will have the scientific language to express the contents of the course in a clear and linear way both to the specialist and to the non-specialist;
- (D5) will be able to distinguish "myths" from science when speaking about energy and ecological transition.

Teaching methods
The course counts 24 hours of frontal lectures, during which students will learn what energy and ecological transition are from a scientific point of view. The slides used to support the lectures will be uploaded on a weekly basis on the Elly platform. The lectures recordings will be uploaded on the Elly platform and on the class YouTube channel.
Assessment methods and criteria
The exam is an interview (oral exam, 30-40 minutes). The interview is conducted to verify the proper learning of the concepts discussed during the course (see course program). The interview is graded on a 0-30 scale. Honors given in the case of excellent control of the disciplinary vocabulary. The mark is communicated immediately at the end of the interview itself.
