How do we organize our future energy supply? This book takes you on a journey through the energy transition and its diverse facets and changes. It paints a picture of the new energy world through well-founded and exciting examples from the energy market, from companies and organizations, and from our daily lives. This creates mosaic-like approaches to implementation. Many different actors are realizing the energy transition through concrete projects. The aim of the book is to foster understanding of the methods and goals of the various actors in the energy transition, to increase acceptance, and perhaps to change one's own way of thinking. The book does not present a solution to the problems of the energy transition; that would be presumptuous. Rather, it contributes to a broader and more comprehensive discussion about the entirety of the energy transition. It is aimed at everyone.
