Sg.hu – Green server centers can come

In the future, there may be installations that sequester more carbon dioxide than they emit.

Although data centers are becoming more environmentally friendly, their consumption is still increasing. Consumption in European computer centers alone has increased from 56 TWh / a to 87 TWh / a in the last ten years, an increase of 55%. Scientists have predicted that this value will increase to 98 TWh / a by 2030.

Wilfried Ritter, 29, is a managing director of a company called Windcloud, which opened its computer center last August. The building in Enge-Sande, Schleswig-Holstein, Germany, is home to thirty server cabinets. The center will consume 790,000 kilowatt hours of electricity per year, but thanks to its design, it will sequester more carbon dioxide than it emits. If the solution works, it could be a major step forward in the area and allow these facilities to be truly green.


By Ritter developed solution is powered by 100 percent green electricity provided by wind turbines operating in the North Sea. The other special feature is the system developed with Novagreen, which builds on microalgae. At the top of the structure are optimal conditions for growing algae, which are later used for cosmetic, medicinal or food purposes.

Windcloud cools its server rooms with fresh air and also operates two facilities for growing microalgae. One is placed vertically while the other is a 10 x 6 meter pool. Microalgae are collected once a week. In this case, the water is pumped off and the microalgae are passed through a filter and finally dried. The heat from the server rooms is used for the latter purpose. Microalgae photosynthesize, utilize water, air, and carbon dioxide, and then produce air.


Ritter also acknowledged that the method has yet to prove and would use fuel cells for a larger facility, while computers would be cooled with water rather than air and the entire building would be built in a more innovative way.

Significant sums could also be saved in the field of energy-saving supercomputers with two important changes to the name of Volker Lindenstruth. The first step is to replace the processors with video cards. This transition may allow for a reduction in consumption of at least 50 percent. The second main thing is cooling: Lindenstruth circulates simple tap water in the system, which then leads back to the rivers. Applying water cooling to all server centers could save € 15 billion and 21 million tonnes of CO2 per year. All of this is important simply because, according to calculations, sending an email emits one gram of carbon dioxide, an hour of video streaming is equivalent to an hour of driving, while billions of likes and searches could fly multiple times across the Atlantic. ocean.
