The fields cannot be separated from
the energy necessary for them to exist. Such is the basic
nature of EM waves.

I would go the other way... the energy can not be separated from the fields.
the fields are the 'more basic' components, energy and power can always be
calculated from them... but you can't always go the other way without
carrying along extra phase information that isn't necessary when talking
about (scalar) power or energy.
