Google's data centers are greener than ever

Google has revealed that its data centers are twice as energy efficient as a typical enterprise data center thanks to more than a decade worth of work spent on improving their energy usage and cooling. In addition to being the world's largest corporate purchaser of renewable energy, the search giant has also taken action on climate change by minimizing the amount of energy it uses in the first place. In a blog post detailing Google's work on making its data centers more energy efficient, the head of engineering at Google Cloud, Urs Hölzle pointed to a new paper in Science which validates the company's efforts. The study found that efficiency improvements have kept energy usage almost flat across the world's data centers, even as demand for cloud computing is at an all time high.
