According to the educational objectives of the Master Degree, the specific educational objectives of the course are to give specialized skills in the field of energy conversion systems based on the use of renewable energy sources.

The main learning outcomes of the Renewable Energy Technologies course are as follows:

Knowledge and understanding
• Achieve the basic knowledge about the structure of the national energy system and about the grants for energy production from renewable sources.
• Achieve the basic knowledge about the main characteristics of wind, solar radiation, hydraulic resources and chemical-physical properties of biomass.
• Achieve the basic knowledge on the fundamentals of wind farms, hydroelectric, solar and biomass power plants.
• Achieve the basic knowledge on the system configurations and performance provided by wind farms, hydroelectric, solar and biomass power plants.
• Achieve the basic knowledge on the environmental impact produced by renewable power plants.

Applying Knowledge and understanding
• Achieve the ability to analyze the results of experimental data of wind speed, hydraulic resources and solar radiation for the purpose of evaluating the energy potential of a site.
• Achieve the ability to perform the preliminary design of a solar thermal plant, a photovoltaic system and a concentrating solar plant according to the user requirements.
• Achieve the ability to perform an economic preliminary evaluation for a power generation plant using renewable sources.

Making judgements
• Achieve the ability to find technical and cost data from the equipment suppliers in order to perform a comparative assessment (qualitative and quantitative) between different energy conversion systems based on renewable sources.

Communication skills
• Achieve the ability to sketch the scheme of a renewable energy power plant and to describe the corresponding operation procedures.
• Achieve the ability to write a technical report about the design process of a renewable power plant.

Learning skills
• Achieve the ability to integrate the knowledge with that of the other courses in order to achieve a general learning in the field of energy conversion systems. The course will also allow to consolidate the skills required by PhD or other master courses as well as for the professional training.


A profitable study of the renewable energy technologies course requires a suitable knowledge of math (algebra, derivative and simple integrals), thermodynamics, and the basics of fluid machines and energy conversion systems. Fundamentals of fluidodynamics, chemistry and electrical engineering is also useful.
There are no formal prerequisites with other courses.

Teaching Methods

The course has a total duration of 60 hours, 40 hours of lectures and 20 hours of practical exercises. Lectures will be held in classrooms and could also be integrated with online teaching resources. The discussion of plant schemes and figures will be done with the use of Power Point presentations. The practical exercises are solved in the classroom by the teacher and concern the design and the performance evaluation of the different renewable energy systems. For each topic, the teacher will assign to the students a specific homework which includes practical problems about the different renewable energy technologies, which represents the basis for the oral discussion during the final examination.

Verification of learning

The final examination is based on an oral examination.
The oral examination consists of a discussion of the exercises carried out by the student and submitted to the teacher. The discussion concerns also on the characteristics and performance of the different renewable energy technologies.

The final mark depend on the marks of the homework (30%) and oral examination (70%).

For the evaluation of the homework the following criteria are applied: a) suitability of the solution process, b) suitability of assumptions, c) Correctness of calculations, d) Effectiveness of ghaphics and discussion of results.

The mark of the oral examination test is reported on a 30 basis. The rank of 18/30 is assigned for an elementary level of knowledge/ability while the rank of 30/30 is assigned for an excellent level of knowledge/ability.
The following criteria are applied for the evaluation of the oral examination: a) Correctness and completeness of answers, b) Analysis of the problem, c) language skills , d) Effectiveness of presentation. Criteria a) and b) are strictly required to pass the examination.
