Renewable energy represents a game changer for interstate energy relations. The abundant and intermittent nature of sources, possibilities for decentral generation and use of rare earth materials, and generally electric nature of distribution make renewable energy systems very different from those of fossil fuels. What do these geographic and technical characteristics imply for infrastructure topology and operations, business models, and energy markets? What are the consequences for strategic realities and policy considerations of producer, consumer, and transit countries and energy-related patterns of cooperation and conflict between them? Who are the likely winners and losers? The Geopolitics of Renewables is the first in-depth exploration of the implications for interstate energy relations of a transition towards renewable energy. Fifteen international scholars combine insights from several disciplines - international relations, geopolitics, energy security, renewable energy technology, economics, sustainability transitions, and energy policy - to establish a comprehensive overview and understanding of the emerging energy game.
