In my speech I would like to compare Intra and Extraeuropean options for an energy supply with wind power. I will give a short inside in the wind energy potentials and point out the change of the temporal behaviour if different catchment areas are used. Thereby we strive the topics of backup and storage needs and the subject of grid capacities. After this I consider wind energy as major source of power production. And last but not least I am going to reflect about a possible combination of climate protection and development aid.
