Google's DeepMind A.I. Just About Cut Its Power Bill in Half

The company's cutting-edge A.I. is using its virtual brains to cut electricity costs at Google data centers. And like it did at Go, DeepMind excels at this game -- it figured out how to reduce cooling bills by 40 percent. Beating a world class Go player was one kind of achievement for A.I., but this development could wind up making that seem trivial. Google's fed massive amounts of information on its data centers' energy consumption habits into an "ensemble of deep neural networks," hoping that the smart-machine could make some efficiency updates. Engineers have long toiled to reduce consumption in data centers, which are (necessarily) notorious energy sucks, mostly because Google cares about reducing its impact.
