> Using the prompt, “How much water is likely to evaporate from data centers in California per year, assuming they are all using mostly evaporative cooling?” several free AI websites provided ranges of estimates, below. These AI also can provide ranges and sources for calculation assumptions.
Data centers with closed loop cooling systems are absolutely built all of the time. Total evaporative cooling has the advantage of being more power efficient (and therefor cheaper) - the only reason they bother with total evap is because the water is being offered plentifully and cheap.
People have no reality of how cheaply priced industrial water is in this country. My parents had a cherry orchard and their annual water bill was $100 an acre per year for as much as they wanted. Which is why the water consumption for data centers is only still a fraction of what we lose to evaporation from inefficient spray irrigation.
