Coming crisis is water consumption by Data centers

Currently, many data centers use water to remove waste heat from servers. The warmed water is piped to cooling towers, where a separate stream of water is turned to mist and evaporates into the atmosphere. Like sweat evaporating from the body, the process removes heat from the piped water, which returns to chill the installation. But large-scale replenishment of the evaporated water is needed to continue the process. Thus, an increasing amount of water will be needed worldwide to evaporate heat from the growing number of data centers, which themselves are increasing in size as more users put information into the cloud (https://www.sciencedaily.com/releases/2016/08/160831224020.htm).
Our AI usage is consuming a lot of water which billions of people are lackingg fresh water to drink.
use of the chatbot for 10 to 50 queries consumes about two litres of water – mainly for cooling and power generation (https://www.asiafinancial.com/ai-data-centres-using-much-more-water-than-expected).
