Preface
This book gives an overview of today’s energy problem in the context of a rising
world population, climate change and the shortage of resources. It figures out
systemic connections between energy, water and the carbon cycle of today’s
economyandsketchesa“natural”futureenergyscenariothatissustainable.Dueto
the complexity of the matter, this short book cannot be a complete compendium.
Theproposedsolutionsandno-goesaremeantasastimulusforfurtherdiscussion.

IwanttothankmydoctoraladviserProf.Dr.KlausSchultzewhointroducedmeto
the Working Group Energy in the German Physics Society. He died while he was
moderating a discussion about future energy concepts in 1999. The biannual
meetings of this working group formed the scientific basis of my knowledge of
energy technology. The lecture series Verantwortung für den Frieden
(Responsibility for Peace)1 (1983–1987) that I organized as a young student in a
workinggrouptogetherwithRangaYogeshwaropenedmyeyestothecomplexity
of social, economic, psychological and political issues, on the one hand, and the
impactofscienceandtechnologyontheotherhand.MyactivityintheSEPA(Solar
Energy Partnership with Africa)2 group based at ZEU (Center for international
Development and Environmental Research) atUniversity of Giessen gave menew
insights into the energy and water problems in Africa. Last but not least, my
activities in the DESERTEC foundation and the DESERTEC University Network
allowed me tothink about global solutionstothe energy problemandmy contacts
with Dii (DESERTEC industrial initiative) helped me to understand the economic
point of view.

biased, but this applies to a certain degree also to scientific books and to govern-
mental reports.
Finally,I must mention Dr. GerhardKnies, with whom I worked on a common
European-North African workshop together long before he invented the name
DESERTEC. He is an uncompromising thinker with visions that he follows with
great enthusiasm.
The main ideas in this book were presented already in conferences in
2014,3 20154 and 2016.5 I want to thank my colleagues Prof. Dr. Gerhard Luther,
Prof. Dr. Volker Metag, Prof. Dr. Christian-Dietrich Schönwiese and
Prof. Dr. Hartwig Spitzer for their help, support and contributions during the
preparation of this book.
