Reply to comment by NickDanger3di in Oregon city drops fight to keep Google water use private by ChocolateTsar

You have no idea what you're talking about. The water is being used for evaporative cooling, and what isn't used is recycled. Other methods for cooling might use less water but would use orders of magnitude more energy - in which case this article would be people complaining about Google's electricity footprint instead of water footprint.

For reals. The “best” solution to this problem is choosing the ideal location, and designing the hardware to withstand more extreme temperature/humidity limits.

The Dalles is pretty dry from what I understand, so they use the water to humidify AND cool the air. Building in a location where the outside air conditions are suitable for the servers year round is the best solution from a water usage standpoint.

However there are other challenges with that… such as the availability of usable energy, availability of a work force to build the data centers. If we located all data centers in these “ideal” regions, we would have latency issues for people further away, along with reliability issues caused by a high concentration of assets in a given location.

The google data center next door to me uses chillers for cooling and saves water as a result. As mentioned above, the trade off here is they use a significant amount of electricity, which may or may not be the more environmentally friendly solution depending on the source of their energy.

I’m not saying they can’t do better, but minimizing environmental impact is a huge priority for modern data center design, and they are constantly evaluating designs, and improving upon them for this reason.
