Electrons further away from the nucleus have more energy than the ones closer, as a general rule.

The coefficients on 7s 6p 5d and 4f mean the shell it is in. So 5d is closer to the nucleus than both 7s and 6p, which means it has the lowest energy. 4f is in the fourth electron shell, so it is the closest to the nucleus, thus having the lowest energy.

*This answer was written under the assumption that by energy you mean energy of the electron itself, not the energy it takes to remove the electron.
