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.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
