Calculate Energy in Space - A Guide

[wolram]

Is there a way to calculate how much energy is contained in a set volume of space?

You mean SPACE space (big empty dark stuff that makes up most of the universe )?
You could add up the photon energy of all the photons passing through it in a certain period of time and add any magnetic fields. You could also include the mass of any dust or particles present.
I don't think it's a parameter that is calculated very often.
