Just this week we launched a datacenter hat runs 100% on renewable energy even in case when diesel engines have to turn on and seeking LEED certification: https://delska.com/about/news-resources/delska-newsroom/dels... - the available energy to the DC is always trumpeted in topic. Yeah, we are kind of proud of technical achievements and efficiency achieved.
But we have the luxury as being slightly nordic, not needing to consume water for cooling. And what is not widespread but taking effect is that datacenters are able to give the heat for useful purposes like heating homes. It needs datacenter to be in city and cooperation for gov agencies, but this is the path that is being taken across countries: https://www.weforum.org/stories/2025/06/sustainable-data-cen...
