HP is first to roll out a wind-cooled data center in the world, and in the process making it the most efficient data center to date. Located near the North Sea in northeast England, it is fully air cooled with eight 2.1-meter stainless steel and plastic fans which will suck cold air from the outside, running it through a bunch of filters and channeled into the data center via the floors. That isn’t the only green initiative from HP, as they also make use of light colored server racks which are full well capable of reflecting light, hence reducing the need for additional lighting by 40%. Water-wise, the building also harvests rainwater by storing them in tanks, where said rainwater will be then used to humidify the air cycling into the building as and when required.
