You probably want year round low humidity and relatively low temperatures following the seasonal curves. Oregon's High Desert (https://en.wikipedia.org/wiki/High_Desert_(Oregon) https://en.wikipedia.org/wiki/High_Desert_(Oregon)) is a good one. Apple and Facebook have data centers in Prineville, OR. Google has a GCP data center in The Dalles. Amazon has at least one in Port of Morrow and one in Port of Umatilla. In fact they can be all lined up on a 236 mile stretch. https://goo.gl/maps/inGGCCk2qBb8Bg5z5 https://goo.gl/maps/inGGCCk2qBb8Bg5z5 Back in 2011 Facebook published about the efficiency of Prineville data center, mentioning 100% outside air direct evaporative cooling https://engineering.fb.com/core-data/designing-a-very-efficient-data-center/ https://engineering.fb.com/core-data/designing-a-very-effici... and efficiency of water use https://www.opencompute.org/blog/water-efficiency-at-facebooks-prineville-data-center https://www.opencompute.org/blog/water-efficiency-at-faceboo... ...Now in 2019 we have data centers in various locations across the world but efficiency goals are no different if not more ambitious. So something more flexible was developed and now in production. https://engineering.fb.com/data-center-engineering/statepoint-liquid-cooling/ https://engineering.fb.com/data-center-engineering/statepoin... IIRC it doesn't mean we high deserts aren't special anymore. They still are.
