Abstract

The experiences of numerous lectures about the present situation of the global energy supply and the possible future developments are presented in the form of 10 statements. Although the physics of the atmosphere, climate history and climate change are relatively easy to present, it becomes very difficult or even emotional, if the far-reaching economic curtailments and the proposed laws to limit the emissions are discussed. The subject of an efficient and constructive global energy policy is strongly controversial even within the scientific community and the best pathways into a peaceful emission-free global energy future are passionately disputed. In general, the technical and financial dimensions of the proposed global change to renewable energies turn out to be hardly conceivable. Most frequently, the spirit of the presentation, for instance optimistic, pessimistic or even cynical, creates a stronger impression on the audience than the bare facts beyond comprehension.
