In Brazil, the Chinese social media giant TikTok is said to be the latest company planning a supercomputer warehouse that will use vast amounts of water and energy

There is no transparency on water consumption by datacentres under construction in these cities. Companies do not publish this information voluntarily, and the government refuses to release technical documentation for licensing, citing industrial secrecy.

The large amounts of water used by datacentres keep computers and machines cool, preventing them from overheating.
