You must distinguish free electrons and bonded electrons.

Explanation:

The first electrons indicate their energy by their motion and they can have any (not infinite) value of energy, different of zero. When an electron is confined and bonded in a limited system (as an atom for example), it can have only well defined values of energy (discrete levels), determined by Quantum Mechanics (permitted by the solutions of Schrodinger equation ).
