Dr. Maegaard is Director of the Nordic Folkecenter for Renewable Energy, an institute for the development and implementation of renewable energies located in Denmark. The center has, under his leadership, provided transfer of renewable energy technology to many countries. Dr. Maegaard was appointed the first president of the World Wind Energy Institute, first president of the World Wind Energy Association, and has served as a Renewable Energy Adviser to the President of Mali. For over three decades, Dr. Maegaard has been a director, organizer, and speaker at numerous international seminars, workshops and conferences. He has authored numerous reports, books, and articles in Danish, English, German and Japanese on renewables and sustainable development. Professor Emeritus at the Department of People and Technology, and a professor of physics at the Institute of Mathematics and Physics, both at Roskilde University, Denmark. He is also an independent consultant at Novator Advanced Technology Consulting. Bent Sorensen's research is cross-disciplinary and has resulted in nearly a thousand scientific articles and some 40 books, including foundation work in economic theory (the scenario method, life-cycle analysis) and in energy research (renewable energy resources, technology and applications). Dr. Sorensen is one of the world's leading specialists in renewable energy. He has five decades of experience in researching the field, and has published hundreds of monographs, articles in scientific journals, technical reports, and conference contributions. He has received several awards and has been knighted by Her Majesty Queen Margrethe of Denmark. He has worked at universities in Japan, France, Denmark, Australia and the United States (Berkeley and Yale), has been a consultant to governments and international organizations, a lead author in the IPCC climate assessment recipient of several international prizes and honors.
