Google uses 900,000 servers to power its efforts in advertising, cloud computing, web-based productivity apps, social networking, and the ever-present Google search.And those servers use 0.01% of the world’s electricity.

Of course, this is just a highly-educated guess made by Stanford professor Jonathan Koomey, as reported by Matthew Humphries of Geek.com.

If that figure sounds huge, consider this — data centres as a whole account for 1.5% of the world’s energy use, and as much as 2.2% when you look solely at the US.

So how can Google keep their electricity use so low by comparison? It uses lots of alternative energy sources like tidal, wind, and solar power whenever it’s practical. Check out the video below, which gives us a tour of a Google data centre (they reappropriate shipping containers, which probably helps cut down costs as well).
