Renewable Energy Systems: A Smart Energy Systems Approach to the Choice and Modeling of Fully Decarbonized Societies Third Edition includes updates from globally recognized renewable energy researcher and professor, Henrik Lund, who sets forth a comprehensive methodology for comparing different energy systems' abilities to integrate fluctuating and intermittent renewable energy sources to achieve a fully decarbonized society. The book presents an energy system analysis methodology, providing the results of more than 15 comprehensive studies, examining the large-scale integration of renewable energy and presenting concrete design examples derived from a dozen renewable energy systems around the globe. The book also undertakes the socio-political realities governing the implementation of renewable energy systems by introducing a theoretical framework approach aimed at understanding how major technological changes, such as renewable energy, can be implemented at both the national and international levels. This is a valuable resource for researchers, scientists, engineers, project managers, policymakers, consultants, and graduate students with an interest in planning, modelling, and implementation of renewable energy systems.
