I don’t think that 1MW is something older datacenters consumed. Unless you are talking about a single rack in a corporate server room.

It is a monthly consumption of a poorly insulated house with air conditioning running 24/7. Or around 1344 W of constant consumption.

Older DCs relied on much less efficient compute and cooling, and the only reason why their power usage could be less is simply much smaller scale.
