This book finally creates transparency and orientation in the societal discussion about German energy policy. It offers a concentrated overview of the concept, the current state of implementation, and the costs of the energy transition. Using essential numbers, facts, and arguments, it answers the most important questions in the public debate on the energy transition: Is the energy transition too expensive for individual households? Does the energy transition really undermine the international competitiveness of the economy? Does the energy transition actually cost "incredibly much money" - can we afford it economically? Are the large power lines from north to south really necessary? Is the energy transition still salvageable, or has it already failed? In a concise and informative style, surprising insights and exciting connections are presented.
