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.

Beyond the limits of conventional electronics: stable organic molecular nanowires
24.05.2018 | Tokyo Institute of Technology
The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
