How many grams of CO2 does the average Google search consume? That was the hot topic of debate over the weekend. The UK's Times Online reported that scientists said a typical Google search consumes about 7g of CO2, which is equivalent to the "amount of carbon dioxide as boiling a kettle for a cup of tea."
But Google downright denies this. They said in a recent blog response named Powering a Google Search that the average query only consumes about 0.2 grams of CO2. Clearly, Google is not agreeing with these scientists, because those numbers are way different.
Google then takes the time to explain how Google is very proactive in green causes and explains how a Google search is very green.
The folks in the forums are not happy about this study, not happy at all. Even before Google's response, member lgn1 said, "Also, I suspect those numbers, 7 grams of CO2 per search are way out to lunch. Without power comsumption numbers from google, that physicist is just urinating in the wind."
