"Datacentres, vast warehouses containing networked servers used for the remote storage and processing of data, as well as by information technology companies to train AI models such as ChatGPT, use water for cooling. SourceMaterial’s analysis identified 38 active datacentres owned by the big three tech firms in parts of the world already facing water scarcity, as well as 24 more under development.
Datacentres’ locations are often industry secrets. But by using local news reports and industry sources Baxtel and Data Center Map, SourceMaterial compiled a map of 632 datacentres – either active or under development – owned by Amazon, Microsoft and Google.
It shows that those companies’ plans involve a 78% increase in the number of datacentres they own worldwide as cloud computing and AI cause a surge in the world’s demand for storage, with construction planned in North America, South America, Europe, Asia, Africa and Australia."
