To the credit of Linus Strom who discovered this article, I figured it would be interesting to mention. Each Google search emits 0.2 grams of CO2, not considering the user's computer. That is equivalent to 1kj of energy or the amount of energy your body burns in ten seconds.
The next time you are doing a little research on the web, think of each search processed by Google's data centres.
Just remember how curious we all were when we were kids. We know a lot more than we think, rely heavily on instinct and make assumptions. Write them down on a paper and organize them using the techniques we have learned in this class.
Blog fail... for whatever reason I can not post the link but I'm sure you can find if you searched "Google Carbon Footprint" on Google. hehe
