According to Jonathan Koomey, a guy who would study such things, Google uses 0.01 percent of the world’s energy. Which is… umm… good! It’s good!
Well, it’s a relatively low estimate for a company that uses 900,000 servers. When compared to data centers as a whole, which use 1.5% of the world’s energy and 2.2% of the U.S.’ energy, Google comes across looking like quite the good guy (which is probably just what they want you to think!).
Google’s energy use remains low because of its investments in alternative energies like tidal, wind and solar power, which they use whenever appropriate.
