Energy management adapted, through the optimization of the production and consumption of fossil fuels with simple solutions possible to reduce the total over cost bound to fuel production (in all costs of investment) and consequently the reduction of CO2 emission (less production = less emission), which based on the quality of energy, control of energy and the energy management and to satisfy demand and maintaining equal balance equation: Sigma PD = Pc + Pl with a total cost CT = Sigma Ci feasible and controllable in our case, this optimization allows saving of energy; so this research lies withn the scope of the environmental search for the solutions of optimizations of energy in the electrical supply network (obligation to reduce the CO2 emission). Indeed, and among these main solution of research is the integration of the renewable resources (energy independence and the sustainable development) that it pushes us to consider from now on the energy problem not only according to the economic point of view, but also according an ecological point of view. This with us encouraged to develop our systems of energy on the basis of distributed generation on a large scale including/understanding renewable energy and the high-output solutions energetic.
