As long as there is no electron in 3rd orbit they will have same energy. Differentiation in energy level occurs when there is electron. Same will be the situation with 2nd , 4th , so on.

Dear student
Shell are degenerate in nature i.e.they possess same energy till the time an electron comes in it and carries out redistribution of energy.As Hydrogen contains only 1 electron which lies in 1storbit there will be no repulsion between other shells hence they will remain degenerate.
1s<2s=2p<3s=3p=3d<4s=4p=4d=4f<....and so on.
