Oh look! Another Jonathan Leake story
Performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea, according to new research.
While millions of people tap into Google without considering the environment, a typical search generates about 7g of CO2 Boiling a kettle generates about 15g. “Google operates huge data centres around the world that consume a great deal of power,” said Alex Wissner-Gross, a Harvard University physicist whose research on the environmental impact of computing is due out soon. “A Google search has a definite environmental impact.”
Recently, though, others have used much higher estimates, claiming that a typical search uses “half the energy as boiling a kettle of water” and produces 7 grams of CO2. We thought it would be helpful to explain why this number is many times too high. Google is fast — a typical search returns results in less than 0.2 seconds. … In terms of greenhouse gases, one Google search is equivalent to about 0.2 grams of CO2.
One problem: the study’s author, Harvard University physicist Alex Wissner-Gross, says he never mentions Google in the study. “For some reason, in their story on the study, the Times had an ax to grind with Google,” Wissner-Gross told TechNewsWorld. “Our work has nothing to do with Google. Our focus was exclusively on the Web overall, and we found that it takes on average about 20 milligrams of CO2 per second to visit a Web site.”
And the example involving tea kettles? “They did that. I have no idea where they got those statistics,” Wissner-Gross said.
There was a “clarification” added to Leake’s story:
A report about online energy consumption (Google and you’ll damage the planet, Jan 11) said that “performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle” or about 7g of CO2 per search. We are happy to make clear that this does not refer to a one-hit Google search taking less than a second, which Google says produces about 0.2g of CO2, a figure we accept. In the article, we were referring to a Google search that may involve several attempts to find the object being sought and that may last for several minutes.
So by a “Google search”, Leake meant 35 Google searches. Simply really. I don’t why Google quibbled with that.
