Learning Goals
The objective is that the student acquires competences in the area of wind power in order to know the fundamentals of wind energy conversion, the main technologies of conversion and types of wind power plants. Particularly, the student must acquire competences on the assessment of wind energy resource, selection of technologies and wind turbines, determination of energy production and economic analysis of wind energy systems.

Teaching Methods
- Theoretical classes
- Practical classes for resolution of problems proposed in the classes
- Laboratorial work of aerodynamics in a wind blade and flow visualization
Students will be assessed by:
N1 - resolution of a set of problems
N2 - one main report
N3 - exam
The final mark is calculated by:
0,3XN1+0,4XN2+0,3XN3
