Energy fuels almost everything. Energy is the fuel that is used to exert force like pushing and pulling and lifting etc. But if you can control the force, you won't need the fuel or energy. You can stimulate the force of psychic powers without it's energy. Some say psychic energy is more useful since energy is simpler and since it is a "fuel" you can shape it and apply it to many techniques and moves and stuff like that.
Think of it like this: Psychic energy projects energy on a space to distort it and twist it
Psychic Force just uses the force to twist and distort the space without a spell or technique or projecting any energy.
