This issue has been beat to death. Anyway, I had one of my old bikes up on the stand - the wheels featured 30-year old Suntour hubs. Steel bearings obviously. When spun up by hand, the wheels rotated for several minutes. They would have spun a lot longer if it hadn't been for the air friction from 36 spokes. So how much were the mechanical friction losses? A fraction of a watt?
I suppose I could cut the bearing losses by using superior cup 'n cone bearings instead of the cartridge bearings in these. But it would not be worth the effort. Ceramics are a waste of money.
