2. Institut für Elektrische Energietechnik Prof. Dr.-Ing. habil. Ingo Stadler Wind parks in Germany All technologies for a change to a sustainable energy supply already exist! How to integrate all the wind (and solar) energy into our grids? What to do when there is no wind? What to do when there is too much wind? Source: ISET What are the questions to answer?
