The Climate Energy Nexus: Understanding the Relationship between Energy Production Systems and Climate Trends offers fundamental material on energy and climate systems, progressing to establishing advanced and integrated energy-climate models. Making informed energy planning decisions requires a better understanding of how climate trends, extreme events, and public policy could impact energy production performance, cost, and emissions. This book introduces readers to the development of integrated climate-energy models for multi-scale planning and assessment. Describing the motivation and key challenges in the climate-energy modeling community this reference looks at the fundamentals of climate and energy systems before integrating them into a cohesive analysis framework. Presenting various energy production optimization case studies spanning across urban and national scales; annual to multi-decade long timescales; and various economic and environmental considerations. Practitioners and students interested in climate and energy systems will gain a foundational platform from which to develop informed assessments of future energy use.
