All Google searches use up 260 MW

Even countries like Sri Lanka have 300 MW energy plants. The power generated by Bhutan’s Tala dam is more than 1000 MW. Looks like the data centers are more efficient than we thought.

I’ve had little time for people who criticize energy use of web search. Earlier writing was without too much data, because data was not available. Here are the data.

Every time a person runs a Google search, watches a YouTube video or sends a message through Gmail, the company’s data centers full of computers use electricity. Those data centers around the world continuously draw almost 260 million watts — about a quarter of the output of a nuclear power plant.

Up to now, the company has kept statistics about its energy use secret. Industry analysts speculate it was because the information was embarrassing and would also give competitors a clue to how Google runs its operations.

While the electricity figures may seem large, the company asserts that the world is a greener place because people use less energy as a result of the billions of operations carried out in Google data centers. Google says people should consider things like the amount of gasoline saved when someone conducts a Google search rather than, say, drives to the library. “They look big in the small context,” Urs Hoelzle, Google’s senior vice president for technical infrastructure, said in an interview.
