We study the dynamics of a quantum-coherent thermally isolated Luttinger liquid with noisy Luttinger parameter. We calculate the out-of-equilibrium energy fluctuations as well as the correlation functions of this noise-driven system, and find universal features. By identifying two types of energy moments, which can help tease apart the effects of classical and quantum sources of fluctuations, we argue that the classical source is dominant in the thermodynamic limit.
