A data centre quietly produces heat every second it is operating. Behind the walls, rows of servers process data continuously, turning large amounts of electricity into computing power and, inevitably, excess heat. That heat has to be removed to keep the equipment within safe operating temperatures, adding significantly to the facility’s energy demand. Green Mountain has approached the problem differently at its Norwegian sites, using the country's naturally cool conditions as part of the cooling infrastructure. At one facility, water drawn from a nearby fjord remains at about 8°C at depth. Instead of making cold mechanically, engineers use this naturally chilled water to carry heat away.
