Actually, energy is required, and it's called ionization energy.

No. It takes energy to pull an electron away from the nucleus. In other words, energy is absorbed, not released.

Energy is being ADDED to the system, because you must have something to "pull" the electron away. This "excitation" energy is how you give the electron more energy than normal (exciting it) so that it can be easily pulled away from orbiting the nucleus.
This is how fluorescent lights, TV, etc work. They excite electrons, and we see their effects on a phosphor screen when they hit.

You have it backward. Pulling away an electron consumes energy rather than releasing it. You need to input enough energy to break the bonds holding it in place.
