The string of abilities regularly (not necessarily frequently) used that requires (emphasis on requires) the least amount of energy would be shredx3, rakex1 and an FB. This would be 93 energy or 18.6 energy per second, 8850 rating would be necessary, 8222 with DI.
If bloodlust is active, you'll need 4749 haste, 4238 with DI, to energy cap in the first case, or 3853, 3368 with DI, to energy cap in the second case. I didn't take into account the extra 25 energy FB can consume, so I doubt you'll be energy capping even with hungerer/matrix(haste) procs and BL active.
