PURPOSE: A network system is provided to inexpensively operate an electric product. CONSTITUTION: An energy consuming unit consumes energy generated from first and second energy generating units to perform an operation to achieve a preset target value. An energy distributing unit distributes energy transferred from the first and second energy generating units to the energy consuming unit. The energy managing unit adjusts the percentage of energy transferred from the first and second energy generating units according to information about the energy of the first and second energy generating units. A display unit(330) displays information about the energy generated by the first and second energy generating units.
