CM True, but voltage cannot exist without energy.

I wouldn't say that. Voltage is kind of like having a big boulder
sitting on top of a high cliff. It doesn't do anything so it doesn't
expend energy. However, if it rolls off that's splat! Similarly you
can have all the electrical potential you want but as long as no
charges flow then where is the energy? In an EM wave it is the energy
itself that flows in space using voltage and magnetism as a skeleton.
