Le site de l’entreprise en dit un peu plus long.

Green Mountain has a unique site, it is a former high security NATO ammunition store now rebuilt into a data center.

The drawing below shows the 6 mountain halls and the 100 m long upwards sloping tunnels leading into the data center buildings inside the mountain.

The high security aspects of the location is of ‘course be fully maintained and the data center is built according to high level standards and in accordance with Uptime Tier III and on most aspects Tier IV level.

Détails sur l’approvisionnement en électricité et sur le refroidissement.

Green Mountain is located adjacent to a deep fjord. At levels below 75 m depth the water temperature is stable at 8°C all year round. Green Mountain has built a dedicated cooling system using gravity effects to bring the cold water from of 100 m to the datacenters cooling station without using any energy.

et dans l’explication du 100% Green, de passage très « écolo » :

Norway is a net exporter of renewable electric power and this is expected to continue for the next 20 – 30 years. The result of this is that the power prices in Norway are significantly lower than those of UK and Continental Europe. It is predicted that this will remain the case for the forseeable future.

Et prochainement, à Rjukan

Green Mountain Data Centre has recently started the building of a second data centre at Rjukan, Norway. Further informatiom about this new development will follow shortly, but here are some headlines:

Rjukan is one of the cornerstones in the Norwegian industrial history. Norsk Hydro built their first large production factory of fertiliser here in 1911, based on the abundant availability of hydro power.

Rjukan also became well known during the second world war, when the German occupants set up production of heavy water (D2O) in the race to establish nuclear capability. The sabotage action that destroyed the factory has been filmed several times (see photo of the Vemork Power Station above). Lately Rjukan has become known because of a new development – their sun mirror. The valley has several months of the year without sunlight due to the spectacular steep mountainsides blocking for the sun. Now they have installed a mirror on the mountainside securing sunlight to the town square during winter.

C’est qu’avec toutes les données qu’on va pouvoir transmettre grâce aux montres qui calculent nos pas, surveillent nos rêves et compte combien de fois on va aux toilettes, ça va en faire des data-centers « verts » en plus !
Je ne vois pas comment un data_center peut être vert, à moins qu’il y ait un récupérateur de chaleur qui redistribuera cette chaleur dans les villes ou villages proches.
Là, dans la montagne même, c’est le permafrost qui va être content de dégeler !
