Elemental energy is the force used by many beings in Bionicle to control their elements.
When Elemental energy is used up the being cannot use their element until it is restored. Elemental energy should not be confused with Toa Energy which cannot be replenished, only belongs to Toa and if used up the Toa will become a Turaga.
Elemental energy can be restored by resting or can be restored quickly by using the Kanohi of Elemental Energy.
