US physicist Alex Wissner-Gross claims that a typical Google search on a desktop computer produces about 7g CO2. His study claims that only two Google searches on a desktop computer produces 14g of CO2, which is the roughly the equivalent of boiling an electric kettle.
As per this Harvard University academic, Google isn’t any worse than any other data centre operator. If you want to supply really great and fast result, then that’s going to take extra energy to do so. Two search requests on the internet website Google produce “as much carbon dioxide as boiling a kettle”.
Although Google is renowned for returning fast results, it can only do so because it uses several data banks at the same time and these carbon emissions stem from the electricity used by the computer terminal and by the power consumed by the large data centres operated by Google around the world.
However, these figures were disputed by Google in its blog, who say a typical search produced only 0.2g of carbon dioxide
