Energy is everywhere—yet the vast infrastructural networks that power our daily lives remain largely invisible. Accounting for three-quarters of global greenhouse gas emissions, the energy sector stands at the center of our climate crisis and the transformations needed to address it. This book examines energy supply as a spatial and material phenomenon, exploring the Berlin-Brandenburg capital region through maps, drawings, texts, and photographs. It reveals the hidden geographies connecting energy production and consumption across scales—from household transformations to citywide configurations and regional supply networks. Tracing the flow of fossil and renewable energy carriers through territories, towns, and streets, Power, Flows, and Transformation offers a multi-layered portrait of our energy landscapes past, present, and future. Graphic exploration of the interactions between energy supply and its spatial contexts Numerous maps, plans, and drawings depicting visible and invisible energy systems Holistic perspective on the development of the diverse energy landscapes in Berlin and Brandenburg
