Standby is a waste of time and energy

04.10.2007
Consumers are repeatedly warned that leaving their electrical devices in standby mode wastes large amounts of energy and makes a significant contribution to carbon dioxide emissions. And therefore regulations are needed, which urge manufactures of electronic devices to cut down standby energy power, right?

Wrong! According to results of a study published today in the International Journal of Environment and Sustainable Development, there is little point in forcing further reduction of standby power. As electrical devices get more and more efficient, the amount of energy saved through stricter regulation becomes ever smaller and efforts would be better placed improving the overall efficiency of devices in operation.

Hendrik Biebeler and colleagues at the Cologne Institute for Economic Research suggests that the European Union directive aimed at reducing the negative environmental impact of technology by attempting to regulate the off switch is at best misguided when it comes to such devices and at worst likely to lead to avoidance by manufacturers in terms of improving the energy efficiency of their products in other ways.

"Our impact assessment demonstrates that the off mode and real standby of a TFT computer monitor and of LCD television sets only have a small potential to reduce energy consumption and carbon dioxide emissions," say the researchers. They point out that regulating the off mode is the most expensive option that saves the least amount of energy when it comes to producing more environmentally friendly electrical devices.

The researchers suggest that regulation of standby energy consumption focuses on only a limited fraction of the total potential to increase energy efficiency by developing devices that are more efficient while in use. More of us are replacing old personal computers that had separate energy-guzzling cathode-ray monitors with TFT monitors and laptops. A TFT monitor uses a third of the energy (25 Watts) of standard cathode ray monitors (75 Watts), but the difference between standby and off mode for a TFT monitor is around one watt.

Gradual phasing out of old energy-intensive components should, the researchers say, be a priority rather than the regulators being concerned with the loss of the small fraction of energy wasted in leaving a device inactive in standby rather than switched off at the mains.

They point out that manufacturers will endeavour to comply with whatever regulations are in place at as low a cost as possible. If the regulations insist on enforced off mode systems, then they will adopt that, but that will save far less energy overall than enforcing greater energy efficiency in device operation.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

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...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

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...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

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...

Im Focus: Self-illuminating pixels for a new display generation

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...
