Enclose a positively charged sphere in neutral concentric spheres as shown in the image. Connect outer surface A to Earth, inner A to outer B, inner B to outer C and finally inner C to the central sphere. These spheres are good electric conductors and are insulated from one another.
When you discharge a charged body using the laws of conservation of energy the electric energy of the current that flows is equal to the energy you put in charging the body, the description shows that on top of Earthing the system we can still get more electric energy flowing in different parts of the system due to the presence of the same charge. So little electric potential energy in the central sphere say 10J is giving rise to say 100J electric energy flow.
Will I get more electric energy flowing than the electrostatic potential energy stored in the central Sphere?
