AI data centers are moving away from cooling towers that evaporate millions of gallons a year. These two briefings explain why hyperscalers are making the shift and show every cooling method, rendered — with what each one costs in water.

Water Is History

Why hyperscalers are eliminating evaporative cooling — the drivers, what Microsoft, AWS, Google, Meta and NVIDIA are doing, six replacement methods, and a Cleveland cost model with a 10-year pro forma.
