In this new edition of Renewable Energy Systems: A Smart Energy Systems Approach to the Choice and Modeling of Fully Decarbonized Societies, globally recognized renewable energy researcher and professor, Henrik Lund, sets forth a straightforward, comprehensive methodology for comparing different energy systems’ abilities to integrate fluctuating and intermittent renewable energy sources and achieve a fully decarbonized society. The book does this by presenting an energy system analysis methodology, providing the results of more than 15 comprehensive energy system analysis studies, examining the large-scale integration of renewable energy into the present system, and presenting concrete design examples derived from a dozen renewable energy systems around the globe. Renewable Energy Systems, Third Edition 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, policy makers, consultants, and graduate students with an interest in planning, modelling, and implementation of renewable energy systems. * Provides an introduction to the technical design of renewable energy systems * Demonstrates how to analyze the feasibility and efficiency of large-scale systems to help implementers avoid costly trial and error * Addresses the socio-political challenge of implementing the shift to renewables * Features a dozen extensive case studies from around the globe that provide real-world templates for new installations
