. According to analysis by the Guardian, two-thirds of planned datacentres in the US are in drought-stricken areas. The larger centres need up to 5m gallons of water a day for cooling, equivalent to the average usage of 50,000 people. It is unclear what the plan is and whose needs will take priority between AI, agriculture and everyone else.
“People are reporting bill spikes,” [Erin]Brockovich says, reading an email from someone who says their monthly water bill went from $22 (£17) to more than $350 (£265). The threat of these centres is about more than money – it feels existential. “How will the water use disrupt the balance of nature? People are asking: “What will happen to us?”
Can somebody explain to me like i’m three, why people always seem to focus on the water they use and not the absolutely out of whack power consumption of these buildings?
Correct me if i’m wrong, but water is never really “lost” whereas power is still a finite and polluting resource so long we still have to burn op liquified or gassified dinosaurs to keep up with demand.
Not a data center expert, but I believe that they use evaporative cooling towers for heat dissipation. If so, the water is in fact lost to the atmosphere.
Water isn’t lost per say, but overusing a water source will deplete it, altering the environment around with no way of knowing how severe the effects will be.
Also, the rejected water can be contaminated (especially with the US relaxing the environment laws)
Energy use is also an issue, but the impact is a lot less severe than water use.
I’m also a lot more concerned about energy use than water. Golf courses use 30x more water than data centers. Residential lawns, arguably the most useless crop in the world, use 9 billion gallons of water every day. Orders of magnitude more water goes into growing corn for livestock feed and biofuels.
The immediate issue is how much electricity AI consumes and where that electricity comes from, as that has the larger impact on public health and the environment. xAI relies on gas turbines that violate environmental rules and pollute the surrounding communities. The surge in demand for electricity is driving the cost higher, further increasing the cost of living for a lot of families.
The ELI3 you requested: All the hubub around water is diverting attention away from bigger issues, which the makes the AI companies and the rich people happy.
That said, I don’t think the water issue should be dismissed either, especially since the water demand is projected to increase fourfold by 2028. They’re both legitimate concerns. I just think energy generation is the one with the greater consequences and should be getting more of the attention.
