This is so empty there isnt even a point to it being posted. MS isnt the only one making datacenters, no datacenter will reduce their power or water consumption, because they havent worked on that in a long time. Including nVidia hardware. nVidia has NEVER reduced power consumption, only increased it.
So, there is no valid information to back any of this hyperbole and BS up.
Even if they say, "sure we will WORK on it", doesnt mean it will happen in a timeframe to help consumers and citizens. Even if MS makes their platforms more efficient, the whole point of datacenters is to host applications that they dont control. So a promise from MS is as pointless as the Microslop they are giving everyone.
