Google’s DeepMind division made headlines earlier this year after its AlphaGo AI beat a Go master for the first time. Now the same technology is being used save money on the search giant’s electric bill, while also helping Google to pay for the costly acquisition of DeepMind. Talk about putting your money to work.
After putting DeepMind in charge of some of its data centers, Google saw its energy usage drop by a few percentage points, Bloomberg reports. That may not sound like a lot, but it makes a real difference. The company consumed a whopping 4,402,836 MWh of electricity in 2014, which is about as much as 366,903 U.S. homes use in the same 12 months.
DeepMind used its neural network technology to reorganize Google’s servers and cooling system. The search giant gave its software control over about 120 different variables, and it may manage even more in the future. The AI will reportedly begin asking for new sensors to be installed in specific parts of the data centers so it can monitor the entire system and continue to improve energy efficiency as it learns.
