As data centers grow ever-larger, their consumption of energy also grows, leading to criticism that the information economy is contributing to global warming. Renewable energy is already being used to produce clean water and power subways. Now a Norwegian company plans to use renewable energy to keep your data cool. Kolos is currently raising funds to build the world’s largest green data center, located above the Arctic Circle in northern Norway. The center will draw on hydro-power and wind for 100 percent of its power needs, allowing Kolos to reduce energy costs and offer very competitive prices for data storage. “It’s quite literally the lowest power cost in Europe – and 100 percent of the power is renewable on one of the most stable grids in the world,” Kolos’ co-chief executive Mark Robinson recently told the BBC.
