How does electrical energy differ from electromagnetic energy?
It doesn't necessarily differ at all. These could refer to exactly the same thing, but one has to look at the situation. Details below...
If you were talking about the energy of electromagnetic radiation, then when you said electromagnetic energy, you were talking about the energy that electromagnetic waves carry through space, which is directly proportional to the radiation's frequency.
When the term "electric energy" is used, the most common applications are probably those involving electric circuits, batteries, or other electromagnetic fields (e.g., generators, solar cells, etc.) that produce electric current through electromagnetic means.
Nevertheless, whether we are talking about oscillating electrons creating those electromagnetic waves, oscillating electrons in an AC circuit, or continuous electron motion in a DC circuit, we are still talking about the energy related to moving electric charge in both situations.
Thus, as was already mentioned, the situation you are thinking about may determine the only true difference.
As the differences are slight, I hope that helps a little.

Electromagnetic energy, on the other hand, is a type of energy that is made up of electric and magnetic fields oscillating together and propagating through space. Electrical energy is the energy associated with the movement of charged particles, usually through conductors like wires.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
