Employing the relativistic kinetic equations for the neutrinos interacting with a plasma via the weak interaction force we explore the different collective plasma instabilities driven by neutrinos. We examine the anomalous energy transfer between the neutrinos and the background plasma via excitation of electron plasma waves (neutrino streaming instability), and the generation of quasi-static B fields (electroweak Weibel instability). The relativistic kinetic equations in the presence of strong external magnetic fields will be derived. The influence of the axial vector potential for neutrinos propagating in a magnetized plasma on these instabilities will be presented. The presence of the magnetic field gives rise to a new route for flavour oscillations, which we describe. The relevance of the electroweak plasma instabilities for the extreme conditions occurring in the lepton era of the early universe, supernovae, and gamma ray bursters is pointed out.
