This course will address energy systems and policy, focusing on opportunities and constraints for sustainable energy transitions. The course introduces energy systems, including how energy is used in society, decarbonization pathways for energy, and the social and political challenges of transitioning to zero carbon and resilient energy systems. Drawing on real-world case studies, students will learn about energy sources, end uses, technologies, institutions, politics, policy tools and the social and ecological impacts of energy. Students will learn integrated and interdisciplinary approaches to energy systems analysis and gain skills in imagining and planning sustainable energy futures.
