In the case of reality, there are many forces but we can understand them. Quick review so we don't look dumb for a minute.
Natural forces that output or manipulate energy directly:
Electromagnetism, gravity, the strong and weak forces. Well these all mess with energy in their own way uniquely so. If you had "full power over energy" you'd likely have to have some form of mastery over these at least. Which would trickle down to concepts that these forces interact with or cause. Inertia/momentum, which is like Kinetic Manipulation or something similar.
Hop would argue Matter Manipulation, too (remember E=Mc^2, which is energy = mass of entity * speed of light squared). So matter and energy are "the same thing" in different forms. So if someone controls "all forms of energy" they likely have access to that too, but how strong or to what degree depends on the context of the feats in the verse, etc.
The list is extensive but not literally endless. Given we're assuming real life.
