“Renewable electricity will become the cheapest source of energy throughout Europe“, says the lead author of the report Prof. Dr. Olav Hohmeyer. The calculated costs are significantly lower than the pessimistic assumptions of the draft EU Energy Road Map 2050, which has been leaked to the media recently.
The SRU launches the scenario results for each of the 36 countries in the European and Northern Africa region together with the English version of its special report „Pathways towards a 100% renewable electricity system“. The scenarios assume a cost-optimized mix of renewable energy sources and a high level of national self-sufficiency. Wind power is for most European countries the cheapest technology, in the Mediterranean region high shares of solar power can also be expected. A completely renewable electricity system, that guarantees security of supply at every moment throughout the year, is achievable at system costs of 65 €/Mwh including the cost for grid expansion and storage. In countries with comparatively greater renewable potentials costs can even be lower. The pump storage potential in Norway is sufficient to function as the “green battery” of Europe.
A leaked draft of the Energy Roadmap 2050 of the European Commission has been recently discussed in the press. The European Commission compared different low carbon scenarios. It concluded that to achieve its climate targets until 2050 a share of renewable energy in the electricity mix between 59 – 86 % by 2050 is necessary, which implies that in any case renewables would become the most important source. However, the scenario with the highest renewables shares appears as the most expensive one. The Commission results are at a level considerably above the calculations for a 100% renewables based scenario calulated by DLR (German Aerospace Center) on the basis of the ReMix-Model for the SRU.* „The European Commission systematically underestimates the low cost potential of renewable energies for a truly sustainable power system”, comments Prof. Dr. Hohmeyer at today’s presentation of the results in the House of Commons in London. „The cost pessimism of the European Commission is scientifically not well grounded.” Exaggerated cost estimates may undermine political acceptance for further expansion of renewable energy in the EU.
In his special report, the SRU emphasizes that a supportive European framework is pivotal for a national energy transition towards renewable energies. The SRU recommends that the EU formulates ambitious binding targets for renewable energy for the year 2030 and that the future European electricity grid systematically has to match the needs of growing shares of renewable sources in the electricity mix. However, the SRU considers the harmonization of support schemes not appropriate, as the conditions in member states are too different.
* The European Commission has calculated overall cost including tax at a level of 199 €/ MWh, the SRU estimated a level without tax at 65 €/MWh. The figures are not directly comparable – but the orders of magnitude diverge significantly.

The Council is made up of seven university professors from a range of different environment-related disciplines. This ensures an encompassing and independent evaluation from a natural scientific and technical as well as from an economic, legal and political science perspective.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
