Two Google searches equals one pot of tea

A physicist at Harvard University who researches the environmental impact of computing, has equated the environmental impact of running two searches using Google and bringing a kettle of water to boil. About 200 million Google searches are performed every day. Dr Wissner-Gross's study claims that two Google searches on a desktop computer produces 14g of CO2, which is the roughly the equivalent of boiling an electric kettle. So how many kettles of water have you boiled today?
