In this Letter, a protocol called quantum energy distribution (QED) is proposed in which multi-parties can simultaneously extract positive energy on average from spin chains by use of common secret keys shared by an energy supplier. QED is robust against impersonation. An adversary, who does not have common secret keys and attempts to get energy, cannot obtain but give energy to spin chains. Total amount of energy transfer gives a lower bound of residual energy of a local cooling process by the energy supplier.
