This book examines the key technologies being deployed in an effort to tap the potential presented by the world's deserts for siting large-scale solar power applications, and surveys the feasibility of such projects given the remoteness and hostility of these environments. Focusing on large scale photovoltaics and concentrating solar thermal power, the book explains how the systems work, projects that are being planned, the required scales, and the technical difficulties they need to overcome to function effectively. It then moves on to examine the economics of such projects (including financing) and the social and environmental effects they may have. The book also considers the future for these systems as well as other, less developed technologies which may have a role to play. With reference throughout to built or planned projects, and written in a clear, jargon-free style, this is a must-read for anyone interested in the development of large scale solar applications.
