A method for supplying eternal electricity comprises activating a light source by an external power source for impinging light on a solar cell so as to convert the radiant energy of the light into an electric power; supplying a portion of the electric power to the light source for continuous illumination while cutting off the external power source for forming an everlasting power generation; and supplying a remained portion of the electric power to a perpetual battery as a source of eternal power supply. Preferably, the light source is an incandescent lamp, electroluminescent lamp, or light-emitting diode (LED).
