    The two largest research organizations for renewable energy research in the world, the Fraunhofer Institute for Solar Energy Systems ISE in Germany and the U.S. Department of Energy's National Renewable Energy Laboratory NREL have signed a Memorandum of Understanding (MOU) for close collaboration on hydrogen and fuel cell technologies research. The official launch took place on Monday, October 10th at the “f-cell / World of Energy Solutions” conference in Stuttgart.

    Wind power is an important element to achieve sustainability in energy supply. Within the EU project "Riblet4Wind", a team of seven project partners faced the challenge of making the aerodynamics of wind turbines more efficient. One approach was to reduce air resistance. In aircraft construction, it was shown that the functional coating developed at Fraunhofer IFAM with microscopically small grooves – called riblet paint – reduces air resistance and saves fuel. The scientists took advantage of this know-how and adapted the technology to the rotor blades of a wind turbine. The tests under real conditions yielded promising results.

    Scientists at Fraunhofer IWES in Kassel aim to contribute to further cost reductions in wind energy use. They will present results of an large scale expert survey on future cost reduction potential, a simulation model on the failure characteristics of wind turbines and recommended practices for reliability data including an own seminar at the Wind Europe Summit 2016 in Hamburg, the world's largest wind energy event.

    »Wind energy has become an integral part of the energy supply. A new milestone for the transformation of energy supply systems was reached last year with renewable energy now accounting for 29 percent of the gross energy consumption. That is more than the conventional nuclear and brown coal power plants. With 80 TWh, wind energy’s contribution to the gross German energy generation is now 12.4 percent whilst nuclear energy lies at 13 percent. Energy production with offshore wind energy plants is gathering speed« says Prof Dr Kurt Rohrig, editor of the new »Germany Wind Energy Report 2016«, as he outlines the significance of wind energy.
