Abstract: A hybrid system for optimizing energy supplied from energy sources to load device is described. The hybrid system includes a memory, a power and energy module, and a processor coupled to the memory. The power and energy module determines power and energy needed by the load device. The processor executes instructions stored in the memory to receive information associated with the determined power and energy from the power and energy module, and optimizes the energy generated by the energy sources for supplying to the a load device by selecting at least one energy source of the energy sources based on the received information and selection priority of the energy sources.
