What do you mean by 'spend' ? Use ? Require ?
What are these electrons doing ? Electrons are put in motion by electric fields, and take potential energy from the field which becomes kinetic energy.

When they lose energy it goes into photons (light).
Check out Brehmstralung.

But in the absence of something to slow it, theres no reason for it to use/spend energy.

I mean when they move through their orbitals, do they spend energy?

Well, we do mostly believe that each orbital corresponds to a particular energy level, so I'd imagine that would mean they don't spend energy.

As the Earth moves around the sun, does it spend energy? :smile:

Then there's the question of whether an electron in an atomic orbital is "moving" in the classical sense... but that belongs in the Quantum Physics forum.

So it is like I through a ball, and it will have just kinteic energy, right?

No - as far as i know.
The electrons do not move around the nucleus as the earth moves around the sun.
The electrons are described by a wave function which related to the probability of finding the electrons in any location around the nucleus, the electron is not "there" , the constant probability of finding the electron there is "there" and it's spread around the nucleus.
When charge particles accelerate they emit energy as electromagnetic radiation, if the electron was moving around the nucleus as the earth moves around the sun it would emit all its energy.
