No.
The equation you posted gives as much information about what energy is as the sentence “Is is to be” gives about being.
We don’t know what energy is.
Same can be said for just about aspect of reality, physical or otherwise. For example, gravity, electrical and magnetic attraction and repulsion, light/electromagnetic radiation, the workings of the atom, the Big Bang, Dark Energy, Dark Matter, the totally bizarre world of quantum mechanics, on and on.
We have a general idea about what these things are and how to apply them in practical use, but we are still very much in the dark as to their ultimate fundamental nature, and to what is really going on, assuming there is such a single bottom line truth or explanation to everything.
Einstein got it backwards. Matter doesn’t distort space, matter IS a distortion in space. Energy is equivalent to matter so it is also a distortion in space, just at a much lower amplitude.
