"Mountain Battery is a must read for energy historians. Telling a deeply transnational story, Marc Landry illustrates how the vision of a hydraulically powered Europe was used both to bring countries together and to advance the ambitions of economic autarchy and militarization." Stephen Gross, New York University "Marc Landry makes a fascinating case for how technology, geopolitics, and imagination combined to make Europe's modern energy landscape by plumbing and wiring the Alps into giant reservoirs of white coal. It is a story about the surprising interdependencies of coal, hydropower, and ultimately, electricity that has urgent implications for the renewable energy transition ahead." James Morton Turner, Wellesley College "Landry's book is an excellent pioneering study. It skillfully combines exemplary and generalizing passages, which also makes it an enjoyable read."Jon Mathiew, Austrian History Yearbook
