Finding alternative energy sources to avoid a climate catastrophe is a major priority for the 21st century.
Hermann-Josef Wagner is a professor for energy systems and energy economy at Ruhr University of Bochum. He has studied the technical and economic issues involving today's energy supply and that of the future.
