Item Focus point: Geography - A Sea of Mirrors but where? : Will the Solar Energy Partnership between Europe and Africa contribute to an aggravation of regional disparities in Africa?(2008) Schüssler, FrankIn view of the current discussion about the threat of climate change and the increasing scarcity of fossil fuels, many groups, including politicians, entrepreneurs, journalists, and our inter-disciplinary working group arelooking to Africa for a future energy supply. At first glance, the potential for new energy forms from the long forgotten continent seems gigantic. There is a huge potential for wind farms, along the thinly settled coastalregions of western Morocco and the adjacent Republic of Sahara (occupied by Morocco), as well as Mauritania.The wind blows evenly and throughout the year as a result of the North East Trade Winds. Initially, the promise of solar thermal power facilities in North Africa seems particularly compelling especially as the energy potentialis 2-4 times greater than in central Europe. However, a careful evaluation of possible locations from an economic, ecological, and social perspective is of importance.Item Focus point: Solar Energy Partnership with Africa : An Inter-disciplinary Research Project(2008) Düren, Michael; Speitkamp, WinfriedIn the summer of 2007 an inter-disciplinary working group was formed at the Justus-Liebig-University to sound out the opportunities and challenges of an energy partnership with Africa. In a series of interdisciplinary lecturesand at a conference in June 2008 this subject was further explored. Additional conferences and workshops, as well as research projects on certain aspects of the subject will follow. Physicists, chemists, geographers, historians,political scientists, economists, and jurists are currently participating. In the following articles several of the participating researchers present questions and possible solutions from their disciplinary perspectives.Item Focus points: Physics - The Future of our Energy Supply : A Scientific Overview(2008) Düren, MichaelWho really wants to sit in the dark, freeze in the winter, and forego modern methods of transportation? Light, heat, refrigeration, machines, and transportation are just a few of the central engineering achievements of oursociety. All of them are only possible because of the constant availability of something that we call energy. In this article, the subject of our society s energy supply will be explored from the scientific point of view in a clearand simply structured way. This examination will lead to a little known and only superficially abstruse idea: Importing electricity from the deserts of Africa.Item Focus pont: Physics - Solar Thermal Power : The Science and Technology of Solar Thermal Power in Africa(2008) Schäfer, DanielEnergy is the most important of resources and the foundation of all human endeavours. The ubiquity and extensive availability of affordable energy provides the basis for the wealth of the technologically developedworld. The energy problem that the world is facing at the beginning of the 21st century is a complex Issue comprised of three facets: availability, economic efficiency and sustainability. How we respond to this problem willdetermine the shape of tomorrow. Paradoxically, that energy source with the greatest sustainable potential is also the least used: our sun. Solar thermal power stations could provide a possible renewable and environmentallysustainable energy source of tomorrow. These scientific, technical and instrumental fundamentals will be addressed in this article.
