Everybody complains about high energy prices. And yet its so easy to save electricity – simply by switching off electrical appliances completely, rather than leaving them idling in standby mode. The Fraunhofer Institute for Systems and Innovation Research ISI has been investigating possible ways of raising consumers awareness of the energy they waste by leaving appliances switched on.
In a single year, the electrical equipment in German households and offices consumed an estimated 18 billion kilowatt-hours of power while switched to standby mode. That corresponds to almost the entire output of all the wind turbines producing electricity in Germany. Many consumer electronics devices take over 50 percent of their total power consumption in standby mode. “A set-top box for receiving digital TV, which will soon be an essential item in almost every household, consumes about eight watts in standby mode, day in, day out,“ remarks Barbara Schlomann of the ISI.
That doesnt sound much, but when you add it up over a whole year, it comes to somewhere around 54 kilowatt-hours. Multiply that by the approximately 60 million TVs in Germany, and you arrive at a figure of over three billion kilowatt-hours. Little is likely to change between 2004, the year that was studied, and 2015 with respect to the huge waste of power due to appliances running on standby.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
