On Thursday we had a busy school day. The day started with a lecture about "Sun as an energy source", and the lecturer came from Leiden University. After the lecture we went to class rooms with our groups and did some exercises that were related to sun energy.

After the lunch break we had another lecture and its theme was "Energy from wind". The lecturer came from Eindhoven University. The lecture was quite hard to understand and that is why it was hard to concentrate also to listening. After this lecture we had to so some data-processing; we had gathered data during the whole week and now it was time to process gathered information.
