Web: Google uses AI to cut data centre energy use

July 2016 by: From The Web

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.


Mustafa Suleyman, DeepMind’s co-founder, said that the level of complexity and number of variables meant the job of managing data centres was one where an algorithm could outperform a human.


He said: “It’s one of those perfect examples of a setting where humans have a really good intuition they’ve developed over time but the machine learning algorithm has so much more data that describes real-world conditions [five years in this case].
