The global, regional, and local energy landscape has changed dramatically in the twenty-first century. Many factors have affected what we know about energy: a consensus among scientists on climate change and related support for renewable energy, evolving energy and resource extraction technologies, growing resource demand in the developing world, new regional and global energy governance actors, new major fossil fuel discoveries on land and underwater in states that have previously been under-resourced, rising interest in corporate social responsibility in energy companies, and the need for energy justice. The Oxford Handbook of Energy Politics synthesizes the diverse literature on these topics to provide a foundational resource for teaching and research on critical energy issues in international relations and comparative politics. Through chapters authored by both scholars and practitioners, the Handbook further develops the energy politics scholarship and community, and generates sophisticated new work that will benefit all who work on energy issues.
