In the last years cloud computing has become more and more popular. This increase in popularity of cloud services results in higher resource demands on the providers end. More resources mean more energy consumption and thus higher electricity bills. Google consumed 2.68 million megawatt hours of electricity in 2011. In 2016 google said it had proved it could cut total energy use at its data centers by 15% by deploying machine learning from DeepMind, the British AI company it bought in 2014 for about £400m.
