Since 2008, the Global Center of Excellence (COE) at Kyoto University, Japan, has been engaged in a program called “Energy Science in the Age of Global Warming—Toward a CO₂ Zero-Emission Energy System.” Its aim is to establish an international education and research platform to foster educators, researchers, and policy makers who can develop technologies and propose policies for establishing a CO₂ zero-emission society no longer dependent on fossil fuels. It is well known that the energy problem cannot simply be labeled a technological one, as it is also deeply involved with social and economic issues. The establishment of a “low-carbon ... Read moreenergy science” as an interdisciplinary field integrating social sciences with natural sciences is necessary. The Global COE is setting out a zero-emission technology roadmap and is promoting socioeconomic studies of energy, studies of new technologies for renewable energies, and research for advanced nuclear energy. It has also established the Global COE Unit for Energy Science Education to support young researchers as they apply their skills and knowledge and a broad international perspective to respond to issues of energy and the environment in our societies. Comprising the proceedings of the Second International Symposium of the Global COE Program, this book follows on the earlier volume Zero-Carbon Energy Kyoto 2009, published in March 2010.
