Abstract: An environmental energy-saving power generator includes a power generation module, a control module, a power module, a power generator housing, and an I/O module. A processor unit of the control module controls the power management unit and the power management unit controls the power module to supply driving power required by a drive unit of the power generation module during operation; after the power generation unit of power generation module operates, the surplus power generated by the power generation unit, when generating power, can be re-charged to the power module. The environmental energy-saving power generator effectively manages and allocates the power of power module and that of power generation module to lengthen the time when the environmental energy-saving power generator supplies power to the load for operation. The power generation units of power generation module and the drive unit may generate high-efficiency power of voltage, current, and frequency.
