This is the result of a Fraunhofer IWES study commisioned by the Offshore Wind Energy Foundation. The IWES research team around Dr. Kurt Rohrig has analysed three scenarios. In one of them, a focal point was set on offshore wind energy, whereas in the other ones priorities where onshore wind energy or photovoltaics.

If offshore wind energy is gradually extended from today’s 3 Gigawatts (GW) of installed and currently under construction power up to 54 GW in 2050, total costs for the power system are reduced by 900 Million Euro compared to rapid expansion of onshore wind energy, and even by 6.1 billion Euro compared with a photovoltaics-scenario.
As much as 92 % of this cost advantage account for so-called flexibility costs. When electricity generation varies very much, the costs of compensation by storage, back-up power plants and derating of unusable power are higher. Offshore, howewer, the wind is blowing so constantly that at 340 days of the year electricity can be generated. In addition, the power level can be predicted more accurately than onshore.
Therefore, offshore wind turbines can provide ten times more balancing capacity in order to smooth power supply than onshore systems, and costs are only one quarter. Furthermore, considerable cost savings could be achieved by a North Sea offshore grid for Belgium, Denmark, Germany, the UK, the Netherlands, and Norway that facilitates electricity trade.Expert contact:

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
