Google has 12 data centers all over the planet, 6 of which in North America. Recent estimations predict that Google has more than 900,000 servers in all its data centers around the world. Google indexed more than 50 billion pages on all of those servers. This means that If each web page were a piece of A4 paper, a print version of Google’s indexed websites would be more than 1 kilometers high, slightly taller than El Capitan, the iconic granite monolith in Yosemite National Park in California —Now, that’s a book that’s longer than Lord Of The Rings.
Google’s data centers use around 260 million watts of power which accounts for 0.01% of global energy. This power is enough to consistently power 200,000 average homes. Google tries to rely on renewable energy sources to power a number of its global data centers, and in the US the company has even begun generating renewable energy – by selling excess supply back into the grid.
