The book introduces you to the numerous topics of the energy transition with exciting subject matter. At the same time, you will learn about what are probably the most exciting developments in the modern world with the challenges of today; on the one hand with a view to maintaining energy supply security for people, and on the other hand with a view to the many opportunities for future generations. The book explains why the energy transition has not yet become a reality and why the energy transition is now gaining momentum. A book about the energy transition also necessarily deals with structural change and is also a testimony to the huge efforts and challenges that the regions are making and overcoming when the goals are clearly defined and when the regional identity is supported by these goals on an inter-municipal basis. A book about the energy transition is also a testimony to the great efforts and challenges that companies in the energy markets are making and overcoming when established structures are broken up and networked with new or complementary business models, when complementary services are created with the expanded energy products. The success of the energy transition therefore depends crucially on the start and speed of implementation of defined goals, which requires determination and regional identity with the emerging fields of action.
