Google uses AI to save on electricity from data centres - BBC News

Its artificial intelligence division, DeepMind, has cut Google's data centres' energy consumption by 15%, using a machine-learning algorithm. Data centres run the equipment that processes the data consumed by internet users, and it takes a lot of energy to keep their servers cool. Some of the newer ones are now being built in colder climates. But some estimates suggest they are now responsible for 2% of global greenhouse-gas emissions. "Being able to put a dent in that benefits the world in general," said DeepMind co-founder Mustafa Suleyman.
