How is AC current transmitted through power lines if it changes direction regularly after a half-cycle proportionally in the opposite direction?

Question

How does the current flow in one direction if the electrons are hoping back and forth? Shouldn’t the net current be zero?

It is. But power ISN’T directional. Your Light bulb doesn’t feed power back into the system on the AC down cycle. It still uses power.
