We show that when the neutrino minimal standard model (νMSM) with a light sterile neutrino has a long range interaction between the neutrino vacuum charge density and a dark U(1) gauge potential, late time acceleration is dynamically realized. Moreover, the relation between the scale of dark energy, the weak and Planck masses derived by Arkani-Hamed et. al \citeArkaniHamed:2000tc that addresses the coincidence problem arises naturally in this model. Assuming that the cosmological constant is zero by some as yet known mechanism, the only fine tuning in our model is the mass of the sterile neutrino. We show that perturbations of the vector fields are oscillatory and hence, there are no instabilities.
