Insegnamenti propedeutici
Basic background in mathematics and physics usually acquired in a 3-year bachelor’s degree in engineering or physics. Basic contents of meteorology will be provided in the first part of the course.

Modalità di insegnamento
The course is mostly based on class lectures. Part of the lectures is dedicated to two practical exercises to apply methods and tools for the assessment of the solar and wind energy potential of a site. A visit to a wind farm is usually organized at the end of the course.

Obiettivi formativi
Intended Learning Outcomes: 1. Knowledge and understanding: The students will learn the basics of atmospheric processes affecting the availability of renewable energy resources to optimize planning, operation and management of renewable energy plants. 2. Applying knowledge and understanding: The students will learn to use meteorological concepts, models and instruments for the assessment of the availability of renewable energy resources (especially solar radiation and wind). 3. Making judgments: The students will be able to identify the most appropriate information source, critically assess the quality of datasets and the uncertainty of the results from the application of meteorological data processing and modeling. 4. Communication skills: The students will learn the basic technical vocabulary and concepts of the discipline. Through the exercises the students will learn how to write a short technical report. 5. Ability to learn: The students will be stimulated to search for proper datasets and other useful information required to assess the availability of renewable energy resources. They will learn to evaluate critically and sort sources of data according to their use.

Modalità d'esame
Students are asked to prepare two written reports on the practical exercises on the assessment of solar and wind energy resources that will be sent to the lecturer before the oral exam for evaluation. The reports will then be discussed during the oral exam. The oral exam also includes questions to assess the knowledge and understanding of the course topics. - Formative assessment: Anonymous tests on the topics covered: during the course, at the end of each module; ILOs assessed: 1, 2, 3. - Summative assessment: 50% oral exam, theory: ILOs assessment: 1, 2, 3, 4; 50% written reports - practical exercises; ILOs assessment: 4, 5.

Criteri di valutazione
Oral exam at the end of the course, with the aim of evaluating the student's ability to reproduce the topics of the course with critical reasoning. Moreover, students are required to prepare two written reports on the practical sessions proposed during the course. The reports are discussed during the oral exam. The final grade is the result of the evaluation of both the oral exam (50%) and the written reports (50%).

Altre informazioni
Connections with other courses This course focuses on the atmospheric factors affecting the availability of renewable energy resources, as well as on the methodologies and techniques for their assessment and forecast. In this regard, the topics covered in this course can be useful for other courses dealing with the infrastructures and plants to exploit renewable energy resources and in particular: “Hydropower and Wind Power Systems”, “Solar Energy and Smart Water Systems” and “Environmental Fluid Mechanics/Hydropower Plants”. Basic knowledge of the factors affecting meteorological fields can also be useful for courses dealing with energy consumption in buildings for space heating/cooling, such as: “Advanced Applications of Building Physics”, “Building HVAC Systems” and “District Energy Systems Design”. Professional applications of the covered topics The knowledge acquired through this course can be applied to the planning and management of renewable energy plants, with particular regard to solar and wind energy plants. Therefore, these competences can be exploited in companies operating plants and in societies providing meteorological and climate services for the energy sector.
