How does the 3d orbital have less energy than the 4s orbital?

Basically electrons in the 3d orbital have a lot of repulsion because of the electrons that occupy the 3s and 3p orbitals. Considering how the 4s orbital is further away and experiences less repulsion, it requires less energy for electrons to occupy it than the 3d orbital.
