An electromagnetic plane wave has an electric field and a magnetic field. Each component contributes equally to the energy density. Mathematically it is very straight forward to show this is true.
The question is, "Fundamentally, why is this true?" Again, I'm not looking for a derivation. There are no issues with the math, just interpreting the physics from the math. With such a beautiful symmetry there must be a fundamental reason why.
