idk where you've been but the standard for AI datacenters buildouts right now is power-plant size turbine operations up to 1GW in size. not 2KVA Honda generators. notably they are single cycle and not combined cycle used in actual plants which requires burning up to 3x the methane for the same power output. none of this is a big secret.
1GW is around 6,000 cars.
There are probably twice that in the community complaining...
Also the stat is from GE Vernova, they make the generators used.
If you really want to argue without having the flex and bend to grasp at straws, just go with the noise argument, it actually is annoying to people nearby.
