Geothermal energy stands out because it can be used as a baseload resource.This book, unlike others, examines the geology related to geothermal applications.Geology dictates (a) how geothermal resources can be found, (b) the nature of the geothermal resource (such as liquid- or vapor-dominated) and (c) how the resource might be developed ultimately (such as flash or binary geothermal plants).The compilation and distillation of geological elements of geothermal systems into a single reference fills a notable gap.
