Firstly, its not new age, its classical elements. They aren’t “energy” they were how philosophers understood the matter and energy of the universe before they understood atoms, laws of energy, and the periodic table of elements, and so on.
Think about it like this. When my mom was little there were just three kingdoms of life: Plant, Animal and Other. In the sixties they changed that to have two domains and four kingdoms, then in the nineties they have been proposing as many as six and nine.
But did bajillions of life forms change any because of how we classified them?
The classical elements are a way of understanding and interacting with the matter and energy that composes our universe, so is the periodic table and classifications of energy. Just as much as the various denominations kingdoms domains etc are ways of interacting with and understanding life although there could be other ways. What ways are the most useful?
Here are the forms of energy from a modern understanding: kinetic, potential, mechanical, mechanical wave, chemical, electric, magnetic, radiant, nuclear, ionization, elastic, gravitational, intrinsic, thermal, heat and mechanical work. Any of the behaviors of the four classical elements are re-framed by these. Spirit, the fifth element is mostly the domain of metaphysics, religion and spiritual philosophy.
