Prof. Dr.-Ing. Dr. h.c.mult Friedrich-Wilhelm is the retired president of the Federal Institute of Geosciences and Natural Resources, BGR, the Federal German Geological Survey, and the Lower Saxony State Geological Survey. He also served as president of the Academy of Geosciences and Geotechnology and was Visiting Professor at LE STUDIUM, the Loire Valley Institute of Advanced Studies, Orléans/France (Chair "Sustainable Management of Natural Resources"). Before joining the BGR he explored for non-ferrous and precious metal deposits in Europe, North and South America, Australia and SE-Asia for Metallgesellschaft AG, the largest German non-ferrous mining company. His last position was Director of Exploration in Australia, a task interrupted for three years while working for the German Ministry of Economics in the natural resources division. Wellmer also taught raw materials policy and economic geology at the Technical University Berlin. He was awarded honorary doctorates of the Technical Universities of Clausthal and Freiberg/Saxony, the two top German natural resources universities, and the Georg-Agricola-Denkmünze (medal), the highest award of the German mining industry.
Dr. Peter Buchholz  As an economic geologist, Peter Buchholz has been with the Federal Institute for Geosciences and Natural Resources (BGR) since 2005, and since 2012 he is heading the German Mineral Resources Agency (DERA) at the BGR. The main focus of DERA's work is to provide market intelligence to assess potential price and supply risks in raw material markets as well as to develop mitigation strategies for the German industry to diversify supply sources. Before his time at the BGR he worked in the fields of ore deposit research, exploration and commodity trading. In 1995 he completed his PhD on Archaean gold deposits at the RWTH Aachen. Subsequently, he worked as assistant professor at the TU Bergakademie Freiberg, and from 1998 to 2002 asdirector of the M.Sc. Programme in Exploration Geology at the University of Zimbabwe, after which he joined a commodity trading company. His research and entrepreneurial work has been awarded nationally and internationally.
Prof. Dr. (PhD ZA) Jens Gutzmer is the founding director of the Helmholtz Institute Freiberg for Resource Technology. He is professor of economic geology and petrology at the TU Bergakademie Freiberg, Germany and a visiting professor at the University of Johannesburg, South Africa. Born and raised in Lower Saxony, Germany, Jens Gutzmer received his Diplom in Mineralogy from the Technical University of Clausthal-Zellerfeld (Germany) in 1993, followed by a PhD in Geology from the Rand Afrikaans University (South Africa) in 1996. In 2005 he was appointed Full Professor of Geology at the University of Johannesburg, followed by a South African Research Chair in Geometallurgy in January 2008. He defines himself as an economic geologist with a keen interest in geometallurgy and metallogenetic processes during early evolution of the Earth System.
Dr. Christian Hagelüken is Director of EU Government Affairs at Umicore, with a focus on raw materials related topics. Between 2003 and 2011 he was head of Business Development in Umicore's Precious Metals Refining business unit. Previously he had held various management positions in the precious metals department of Degussa AG. Christian has over 25 years' experience in (precious) metals recycling and sustainable metals management and has made numerous contributions to professional books, journals and conferences. He represents Umicore in related policy initiatives, associations, expert groups and scientific panels, among others the UNEP Resource Panel, the European Innovation Partnership on Raw Materials, the German acatech working group on resources for energy applications, and the German National Platform for Electromobility.

Grundlagen.- Rohstoffversorgung und Einflüsse der Weltwirtschaft.- Aktuelle Rohstoffsituation - ein Überblick.- Entwicklung des Rohstoffbedarfs des Energiesystems.-

This is the first book that analyses the future raw materials supply from the demand side of a society that chiefly relies on renewable energies, which is of great significance for us all. It addresses primary and secondary resources and substitution, not only from technical but also socioeconomic and ethical points of view.
The "Energiewende" (Energy Transition) will change our consumption of natural resources significantly. When in future our energy requirements will be covered mostly by wind, solar power and biomass, we will need less coal, oil and natural gas. However, the consumption of minerals, especially metallic resources, will increase to build wind generators, solar panels or energy storage facilities. Besides e.g. copper, nickel or cobalt, rare earth elements and other high-tech elements will be increasingly used. With regard to primary metals, Germany is 100 % import dependent; only secondary material is produced within Germany. Though sufficient geological primary resources exist worldwide, their availability on the market is crucial. The future supply of the market is dependent on the development of prices, the transparency of the market and the question of social and ethical standards in the raw materials industry, as well as the social license to operate, which especially applies to mining. The book offers a valuable resource for everyone interested in the future raw material supply of our way of life, which will involve more and more renewable energies.
