Harvard physicist Alex Wissner-Gross thinks computers could be greener. He’s been researching how much energy they use, and his results are, well, a little surprising. He’s found that undertaking two Google searches produces 14 grams of CO2, about the same amount produced by boiling an electric kettle.

He says the carbon emissions come not only from the computer itself, but from the data centers that produce the information for that search, several data banks at once, he claims.
