In this advice, the Council argues that energy from biomass is a finite resource, which needs to be used carefully in order to maximize its greenhouse gas reduction impact.
Based upon a comparison of available scenarios the SRU estimates, that by 2030 no more than 10% of primary energy needs can be met by domestic sources in Germany. This assessment contradicts recent European Commission forecasts.
Those limits to growth apply, if implementation of existing legislation for nature conservation and water protection are to be fully respected and implemented. As regards some of the special impacts of bioenergy, such as grassland conversion, even stricter national and EU safeguards are needed. Since the use of bioenergies for stationary sources, such as combined heat and power generation or coal substitution, may earn in average three times more CO2-reduction than biofuels, clear-cut priorities should be set.
The overambitious national and European biofuel targets should be revised. The expected import boom requires international agreements in order to prevent direct and indirect damage to valuable tropical forests. The SRU believes, that those agreements may be achievable - but not in the short run.
The report also assesses second-generation biofuels, which may not have a significant market penetration before the end of the next decade and therefore should not be considered, when setting targets now. Furthermore, second-generation biofuels may increase productivity compared to first generation biofuels, but they do not convert the hierarchy of preferred biomass use.The report has received considerable press coverage in German media. The full translation of the report is now available. As the Commission is about to formulate some sustainability criteria, global verification and credible enforcement only are still in there very early stages. Even strict criteria therefore will not be sufficient to ensure sustainability in the short run unless the overambitious expansion of subsidized agrofuel demand is slowed down.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
