They’re rapidly being converted into generators to meet A.I.’s insatiable demand for electricity. Environmentalists call it a step backward.

Wow this can’t be efficient. Jet engines are primarily designed to produce thrust. But looks like Musk got special permission from the state to pollute more, so all’s good!
It is. Jet engines are very efficient. But they also have to run high to reach that efficiency. But if you’re running at high power for most of the time, like a jet aircraft or datacenter generator, then it makes sense. It doesn’t matter whether your turbine shaft is connected to a fan or an electric generator rotor.
That’s true, it’s not as bad as I was originally thinking. However, there’s probably a reason traditional power plants never use jet engines for power production. According to this article, “But repurposed aircraft turbines tend to be less efficient and more polluting than engines designed for conventional gas-burning plants.”
They don’t use used jet engines, no. But a gas turbine for a gas power plant shares many engineering principles with jet engines, and often many shared parts.
And generally, for stationary plants, the heat of the exhaust can be used to boil steam and get another cycle’s worth of work out of the heat, for even greater efficiency.
Not really, the core of a modern turbofan produces rotational energy to drive the fan, the hot part of the engine produces little to no thrust.
This isn’t something new. Jet engines have been converted to power use for decades because once they are beyond the aircraft service life they are still useful for generating power
