You're confusing MW with MWh. Older DCs did indeed consume on the order of 1MW of continuous power, like the one at [0]. The 2012-dated DC at [1] has a redundant 22kW power feed per 42U rack, so that's ~500W per RU - which for most pre-AI servers was plenty.
With hyperscalers it of course went a bit beyond that due to the sheer number of racks, but 100MW would've been considered huge.
Port- or Client-isolation on Ethernet switches and Wi-Fi access points respectively. Often seen in corporate environments and (properly configured) guest networks.
This did not end well for freedom in Russia (see Moscow underground face recognition tech targeting dissidents). This will not end well for democracy in Europe.
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.
