The Elephant In The Server Room: The Overlooked Energy Cost Of Mainstream Compute
HPE, Wednesday, April 22nd, 2026
Mainstream compute uses way more electricity than AI - So why aren't we talking about it?
If you only followed the headlines, you'd think AI is about to single-handedly crash the power grid with its ravenous energy appetite. However, scrutinizing the numbers actually reveals a surprising reality: the lion's share of the current and near-term future data center energy use isn't from AI at all. It's from everything else; the so-called 'mainstream IT' found in corporate IT estates, colocation data centers, and cloud servers. It turns out that, while AI may be growing quickly, it's mainstream compute that is predicted to be IT's biggest data center energy hog.
