TIL about the real cost of a single search query

I was reading an old tech paper from a university library and it claimed a single Google search uses about as much energy as boiling a kettle for a cup of tea. That fact, from a 2009 study, really made me think about all the invisible energy we use every day. Does anyone know if more recent data backs this up or has the efficiency improved that much?

That study's been pretty thoroughly debunked. Modern data centers are way more efficient than boiling water for every search.

Honestly, "way more efficient" is still a pretty low bar to clear. They're still burning a crazy amount of power overall, just less per task. The scale is what gets you.

People forget the energy cost of building all that efficiency. @the_stella is right about the water comparison, but making those super efficient servers and cooling systems takes a ton of resources. The carbon footprint from manufacturing all the tech isn't in the daily usage stats. It's like saying a new car is efficient but ignoring the factory that built it. That upfront environmental debt matters just as much as the power they pull from the grid later.
