What is this Book About?.- The Mineral Voracity of Human Beings.- On the Availability of resources on Earth.- The (Thermodynamic) Value of Scarcity.- The Physical Value of Mineral Resources.- Material Limits of Energy Transition.- The Hidden Cost of Technology.- Looking to the Future.

Dr Alicia Valero is Director of the Industrial Ecology Group of the CIRCE Institute and Associate Professor of the Mechanical Engineering Department at the University of Zaragoza. She has had a successful research career in
the topics addressed in this book, related to the exergy evaluation of mineral resource depletion, among others.

Professor Antonio Valero is Chair in Thermal Systems at University of Zaragoza since 1986 and Founder of the Research Centre for Energy Resources and Consumption, (CIRCE). He is full Member of the Club of Rome Intl. and
ASME Fellow. He is a main contributor of thermoeconomics —general theory of exergy saving, diagnosis of complex energy plants —and exergoecology,  applied to evaluate the exergy of resources of the earth, from which Thanatia is derived. He is Winner of the ASME James Harry Potter Gold Medal Award’96, among many other distinctions.

Dr. Guiomar Calvo is Geologist with extensive experience on the subject, providing a necessary counterpoint by combining engineering with geology.

The authors have published numerous scientific articles and books, receiving several international Best Paper awards. They have participated in conferences and talks, for which they have a broad career and an outstanding reputation in their respective fields of study.
