Windenergy I/Windenergy II
The students acquire an advanced knowledge in the field of wind energy applications. Special emphasis is on connecting physical and technical skills with the know-how in the fields of logistics, management, environment, finances, and economy. Practice-oriented examples enable the students to assess and classify real wind energy projects. Special situations such as offshore wind farms and wind farms in non-European foreign countries are included to give the students an insight into the crucial aspects of wind energy also relating to non-trivial realizations as well as to operating wind farm projects.

Solar Energy
„Solar Energy“ conveys knowledge about Photovoltaic and Solar Thermal systems and components. The students learn to dimension and economically evaluate installations, on both a general and detailed level with the help of software. Furthermore, the students will gain insight into the physical and engineering processes for solar energy utilization.
