Google used DeepMind AI to cut its power bill

The company sees more savings ahead, too. The AI now knows where there are gaps in its coverage, and it may tell Google to install more sensors to improve its effectiveness. Software can only do so much to lower the tech giant's power consumption. However, it's a relatively small investment that can pay big dividends, and not just for Google's bottom line -- combined with investments in renewable energy, it could do a lot to help the environment. The results also underscore the sheer flexibility of DeepMind.
