Not sure on the physics, but the biggest factor is the efficiency of the bearings. Something like these will expend very little energy, in the same way that cheap, ill-fitting bearings with sand and dirt in them would wear down the balls, causing them to grind, the friction from this causing a much lower efficiency.
