First of all, Lindsay said that Yang's power comes from her hair.

Second of all, the Death Battle video said Yang's power comes from her hair, and ScrewAttack has connections with Rooster Teeth, so I'm inclined to suspect they might have gotten at least some of their info about Yang directly from Rooster Teeth. Rooster Teeth feeding them info would explain where the hell they got stuff like "Yang can only absorb power if she's conscious" and "Qrow trained Yang" (the second thing, I've made a speculation blog post about).

She stores the energy she absorbs in her hair. Longer hair means more storage, which means more power that she can draw out into bigger attacks or a larger number of powered up attacks.

Like, say... Yang has filled up 5 units of storage. She could choose to use 3 units worth of stored power to do one really big powered up attack or 6 smaller powered up attacks (which each use 0.5 units). That would leave her with 2 units left to use. Forgive me for not using any specific units, as it's almost 2 AM and I'm not entirely sure what units would be appropriate for this situation.
