Do movement of electrons in an atom consume energy?

So, although an electron's location can only be expressed in probability, can we still say that it still moves from one place to another? I understand that not by following an orbit or something, but still it "moves" or "changes place" right?

If so, would it be right to say that an electron (this moving particle) does not consume energy to move?

Please clear my confusions :)

Thank you in advance!

If you think back to your Newtonian mechanics, you'll remember that movement *itself* doesn't require an expenditure of energy - it's just inertia. It's *change* in movement - an acceleration - that requires some energy differential. 

Whether electrons can actually be considered in 'movement' relative to an atomic nucleus is, to be honest, a question of how you define 'movement' at that scale, which doesn't translate directly to classical concepts. But, in its ground state, at least, they are in the lowest energy state it can be in, and that translates, in quantum mechanics, to a sort of 'smear' across a simple harmonic oscillation.

If an electron *were* to experience some acceleration, you'd be able to measure it - accelerating charges induce changes in the  electromagnetic field.
