A method for the production of hydraulic and electric energy from rolling vehicular and non-vehicular traffic, establishing a flow of fluid moving between at least two tanks, the first tank being an accumulation tank, with a fixed volumetric capacity, and the second is tank being an expansion tank, with a volumetric capacity varying between two limit conditions, namely, full and empty. The flow is established by two independent circuits, the second of which is activated after the first, the latter being generated, in turn, by the rolling motion of the vehicular and non-vehicular traffic. The first and second circuit have a flow and pressure reducer system interposed there between.
