Google uses AI to cut data centre energy use by 15%

Google says it has cut its vast data centres' energy use by 15% by applying artificial intelligence to manage them more efficiently than humans. The servers that power billions of web searches, streamed films and social media accounts are estimated to account for around 2% of global greenhouse gas emissions. Google is believed to have one of the biggest fleets of them in the world. On Wednesday, Google said it had proved it could cut total energy use at its data centres by 15% by deploying machine learning from Deepmind, the British AI company it bought in 2014 for around 400m. Such centres require significant energy for cooling, as well as constant adjustments to air temperature, pressure and humidity, to run as efficiently as possible.
