In this talk I will recall the Onsager conjecture and compare it to the issue of anomalous energy dissipation and to the Kolmogorov 1/3 law . Then I will give a proof of the local conservation of energy under convenient hypothesis in a domain with boundary and show how this implies the absence of anomalous energy dissipation. Eventually I will give several forms of a basic theorem of Kato in the presence of a Lipschitz solution of the Euler equations. Insisting that in such case the absence of anomalous energy dissipation is equivalent to the persistence of regularity in the zero viscosity limit.
