Done right, it actually would.
Powering those centres would require building ton of new power generation, and in the case of a risk of running out of power, non critical infrastructure - like a datacenter - can be disconnected from the grid to redirect that power to the uses that actually matter. Like here in Finland, if we are risking blackouts for homes during winter for example, they will cut power to factories and stuff like that first in an effort to prevent it. It’s part of the contracts for commercial electricity connections, and they have to just accept that.
The bigger the section of non-critical infra you have, the more capacity you can free up in an emergency.
In Texas, though? Not very optimistic it would ever work that way.




If you want actually pretty good smart home stuff, and for cheap, go to IKEA. By default they require nothing but being paired to a button/dial/motion sensor that works entirely on a local mesh network (Zigbee, or more recently Matter over Thread) between the devices. You can buy a hub, which again by default is local only - to control the lights using your phone you need to be connected to your own wifi. And if you really want to control them from somewhere else (or use Siri/Google Assistant etc), you have to specifically enable that functionality.
And because they use matter, they work with most of the other matter stuff, and vice versa - I have a bunch of Aqara temp/humidity sensors connected to mine. And you don’t even need an IKEA hub, any Matter hub will work, and there are quite a few of them including stuff like the Google Home Speaker, a 3rd gen Apple TV, and the Apple Home Pod.
Main downside? IKEA electronics aren’t exactly the most reliable things around.
