The truth about data center water usage

The truth about data center water usage8 oct44 min

Of all the concerns surrounding the AI boom, data center water usage tops the list. Opponents claim that massive hyperscaler facilities threaten local drinking supplies and drain aquifers. Proponents say data centers use a negligible amount of water, at least compared to agriculture or conventional power generation sources. 

So who actually has it right?

In this episode, Shayle sits down with Tim Shedd, founder of Ebullient Insights and an expert in data center thermal management. They unpack the history and evolution of data center cooling and consider how high-density chip racks have developers ditching air cooling in favor of single-phase direct-to-chip liquid cooling. The two also discuss:

- Why modern GPU racks (drawing 220 kW to 500 kW+) have rendered traditional air cooling obsolete

- The distinctions between single-phase direct-to-chip, two-phase cooling, and immersion cooling methods

- How collecting heat at higher temperatures inside a server allows data centers to reject heat outside with far less energy and water inputs

- How developers can better communicate with the public about data centers’ water usage and foster local trust amidst rapid buildouts.
