What makes AC electricity alternate directions? How do electrons get anywhere if they just keep going back and forth?

Is it similar to the waves on the surface of an ocean, where the particles go 2 steps forward and 1 step back in waves? If so, what makes it do that? Why would that be used instead of DC current?

With something powered by AC current, we aren’t taking advantage of a constant supply of new electrons… we are instead making use of the MOVEMENT of electrons. Doesn’t matter if they are moving one way or the other. Movement = energy
