"Dark energy", however, as far as I know, has not been evidenced by any observations and that is supposedly 73% of reality."Dark energy" does have an effect that can be observed: The fact that not only is the universe still expanding, it's accelerating.
To accelerate, an 'energy' or 'force' of some type must be placed on it.
The name given to this yet unknown force, "dark energy".
No one is saying, "This is what dark energy is."
They're just giving that name to whatever the force is that is causing the universe to accelerate.
