The cost of datacenters is getting expensive. Therefore I will build them on the Moon. Where I'll also be building my satellites. That I'll be yeeting into Earth's orbit with a giant space catapult. Because I'm all about low cost.

The thing about this story is that there's so much data on market prices, T&D spending, etc. And the "reporting" on it basically ignores the data.
