Ok so keeping a symmetric load spinning wouldn't be that much - only whatever energy is required to accelerate the load to whatever angular velocity and all the energy losses you get at the bearings. However, since it's asymmetric there's excess load on the bearings all the time because you've got to force the load to rotate about a non-preferred axis.

Need to know the losses at the bearings, the time of the cycle etc.
