The energy of galaxies is not red-shifted. The light is. That's because it's moving away. The wavelengs of the light are increased because it's moving away, that's why it's red. That doesn't have anything to do with the energy state of an object.
Yes, Energy is conserved on the scale of the universe. That would be the perfect conservation. It doesn't have a non-universe to go to.
It’s clear that cosmologists have not done a very good job of spreading the word about something that’s been well-understood since at least the 1920’s: energy is not conserved in general relativity. (With caveats to be explained below.)
So where is the energy that was once contained in the photons after the photons have been redshifted?
Graph, they didn't go anywhere. It's the same photons.
If the wavelength shortens, it gets more "blue" because that's the color of light with a short wavelength. If the wavelength lengthens, it gets more "red" because that's the color of light with a long wavelength.
The photon is still the same light. It's Doppler Effect of light.
If a car drives towards you, the engine gives a higher pitched noise because that's the wavelength of sound with a compressed wavelength. When it passes you, it gives a lower pitched noise because that's the wavelength of sound with a lengthened wavelength. But within the car, the noise is always the same.
Sound wasn't lost when it passed you going from high to low pitch. The wavelength of the sound changed.
I asked where the energy goes, you tell me the photons don’t go anywhere. Obviously. I’m talking about the energy contained in the photon. You realize you can have high energy photons and low energy photons right? The difference between infrared and gamma rays? I’m sure you’re aware of the concept. Cosmological redshifting is “lowering the energy of high energy photons” - the question I socratically put to you was “where is that energy going?”
If a car drove towards me, and the road kept on stretching between us so that the car would never reach me or atleast take longer to do so, the stretching of the road would violate the conservation of energy.
Doppler redshift != cosmological redshift that’s a low level mistake of comprehension. Cosmological Redshifting literally removes the energy from the photon and it goes “nowhere” according the the standard model.

No, it wouldn't. That's the point. You might argue the stretching violates conservation (it doesn't, by the way), but not the car's energy or it's use thereof.

You might think this sounds silly but it’s only because you haven’t thought/read about the subject enough
Here is cosmologist Sean Carroll:

The redshift (or blue shift) is no different.
