The invention relates to an energy on-site collection and metering feedback system, which comprises fitness equipment capable of generating mechanical energy, a generator, an electrical energy meter and an energy-storing storage battery, wherein the fitness equipment is provided with moving parts for doing exercise; the moving parts for doing exercise of the fitness equipment are connected with the generator and drive the generator to generate power; the generator is connected with the storage battery through the electrical energy meter for metering generated energy; and the electrical energy meter comprises a bank card reading and writing machine having data reading and updating functions. The electrical energy meter can calculate the energy generated by the exerciser at each time of exercise and display the energy, and a data processing main machine can sum the energy values generated by different sets of equipment in the same field. Thus, the exercisers have more interests in doing exercise and do exercise frequently.
