How much does a search on Google cost in carbon dioxide? * You get two different answers. One from US physicist Alex Wissner-Gross. He says it takes about as much carbon dioxide to do two Google searches as it does to boil up a cup of tea using an electric kettle. That's about 7g CO2. * Google will beg to differ. Those two searches, according to the giant search engine, will only burn up 0.2g of carbon dioxide. By their accounts, you would need to muster up several more searches to fry up as much kettle as Alex Wissner-Gross proposes.
