Tenttien ajankohdat ja uusintamahdollisuudet

Test for Parts I, II and III will be scheduled between 28.10 and 7.11.2025
1 test re-take is possible according to the schedule for the Energy and Environment education unit

Pedagogiset toimintatavat ja kestävä kehitys

The educational process aims at understanding Wind Turbines functionality, and what impact have parameters, type of equipment or control strategy on the size and performance of the systems.
Calculation exercises and simulation projects help the students to think for themselves and understand theory better.
The class is multi-cultural, with a relevant proportion of exchange students, which make lectures like an exchange.
