Since the reactor disaster in Fukushima, the topic of the energy transition has become a cross-generational project in the public eye. However, the roots of the energy transition go back much further. But who can truly claim to understand what lies beyond the superficially conducted pro and con debates? The mechanisms of our electricity supply are complex, and populist demands from lobby groups often hinder objective opinion formation. Philip Würfel sheds light on this darkness with his book. He clearly explains the complex interrelationships of the energy industry and conveys the revolutionary restructuring process of electricity supply in Germany, which is also widely discussed abroad. Numerous examples from both private and professional life provide repeated "Aha" moments while reading. The revised and updated edition.
