Ever wonder where all your accumulate search data goes? It gets distributed to one of many of Google data centers. All of which are mostly eco-friendly.
What Google does to cool those servers is also very interesting. Colored pipes run hot and cold water around the facility. Water is sprayed out of small pipes, where it is essentially steam cooled. That cool air is forced down into the server room. The excess condensation is pumped back into the pipes, creating a perpetual water cooling system.
My explanation isn’t the best, but Google would be happy to show you how the whole thing works
