To get started with the real-time kernel for Ubuntu 24.04, check out the official documentation. One thing to keep in mind if you’re an NVIDIA GPU user is that the real-time Ubuntu kernel does not support the proprietary NVIDIA graphics drivers.

Why would it increase your energy bill?
I guess, the governor is set to performance for a realtime kernel to work properly, thus the CPU consumes more power.
Partially, but the shift is more in the amount of power required to constantly serve interrupts. That’s essentially what these flags enable. Where previously the kernel would be more lax about scheduling such things, this let’s all those interrupts off the chain. More interrupts = more power draw. The ARM and AMD extensions mean to reduce that in a meaningful way, though.
