Laskern, that’s how I look it as well, Hashem is the source of all energy. Matter, which is all physical things in existence, is energy, energy=matter. So to create matter, to create every physical thing, there needs to be a greater source of energy, the threshold energy, which is greater than the matter particles (pair of fermions) which create matter. I believe Hashem is the threshold of energy, or maybe not the threshold itself but the Infinite Source that provides the threshold for the creation of energy, which equals all matter, gashmius, in the universe.
Hashem is also the source of ruchnius, spirituality, which I believe is also a form of energy because souls and spirits enable life. I remember reading in one of Rabbi Aryeh Kaplans books that there is a misconception that God is spiritual. God is not spiritual, He created spirituality and He is above spirituality and the source of it.
