There is a lot of nonsense talked about this sort of subject:
Data centres use vast amounts of water for cooling. It can be used to absorb heat through methods like evaporation or immersion. The water needed can be significant depending on the system and heat generated.
It is estimated that up to 5 million gallons (approximately 20 million litres) of water is used daily in data centre cooling. By using water in such quantities, data centres are contributing to water shortages and depletion of resources, particularly in countries where water scarcity and drought are prevalent.
Very very few data centres are built in areas of water scarcity and drought. So conflating use of cooling water in, for example, The Netherlands, with water scarcity in African countries, is utter nonsense. Extremely poor logic, and has no relationship with science.
The connection (and there is one) is that data centres use a lot of energy. Energy that, if not produced from renewables, is contributing to climate change.
Hence interest in building data centres in places like Iceland, with its surplus of geothermal energy, or Scotland, with its surplus of wind energy.
