creates greenhouse gases too. as a rough comparison, research suggests a five—minute internet search uses around as much energy as boiling a kettle for a cup of tea. internet search is a really good example because an internet search relies on all the infrastructure, the part that's unseen. and the figures are contested. there is some uncertainty around them. but somewhere there's a machine that's doing all the analysis of the data and all the indexing, which allows the search to be then done rapidly. there's machinery under the surface doing that on your behalf, and each of that has a carbon cost. many in the industry say an online search is nowhere near as bad as boiling a kettle. but what's not disputed is our huge internet usage creates significant greenhouse gases. take our love of viral videos.
