The program will repay its investment costs of €1.9 million in about four and a half years. At the same time, the location now emits one fourth less carbon dioxide - a reduction of more than 2,700 tonnes.
This is the amount of CO2 that would be produced by approximately 18 million kilometers of automobile driving. Siemens Healthcare employs 1,100 people in Kemnath. The ultramodern manufacturing site there produces components for magnetic resonance imaging, CT scanning, and radiography, among other applications.
Since 2006 Siemens has been identifying energy-saving potential at its own facilities and adopting efficiency measures to tap into that potential. More than 100 of the company's 300 plants have already undergone the Siemens Energy Health Check. As a result, electricity consumption at the production facilities declined by 11 percent on average between 2006 and 2010. At the same time, their efficiency with regard to primary energy and district heating increased by almost one fourth.
The savings in Kemnath were due to four steps. Instead of the old gas boilers, biomass boilers that use wood chips as fuel are now supplying the necessary heat. An extra gas boiler is used to manage peak loads. Electricity is supplied by a natural gas cogeneration unit that simultaneously produces heat. The new heating technology was responsible for over 60 percent of the cost savings. In addition, fans and pumps for the air conditioning systems were made adjustable with the help of frequency converters.
Now carbon dioxide sensors measure the air quality, and the ventilation system is adjusted as needed. Savings also result from the use of the latest generation of energy-saving fluorescent lamps, which are automatically dimmed on the basis of input from daylight sensors and motion detectors. Finally, all the buildings are now connected to a completely renovated, efficient central cooling system.
Siemens is one of the world's leading suppliers of green technologies, and the company brings this expertise to bear at its own business locations too. Environmentally friendly and energy-efficient products and solutions are part of the Siemens Environmental Portfolio, with which the company generated about €30 billion in sales in business year 2011.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
