An strange idea for saving electrical energy

It follow from my very strange idea that if a stream of electricity is never allow to reach from positive terminal to negative terminal, then the electrical energy contained in the electrical current is never consumed. Then we can apply this idea in any city to save electrical energy immediately.

The general idea is very simple, this device would have three components:
A. Electrical circuit to detect the voltage of capacitor and switch between two sources of electrical energy: External/Internal, in according to the result.
B. A capacitor that is capable of storing all electrical energy needed for one instance of operation of all electrical energy consumption.
C. Electrical current stabilizer to regulate the electrical energy discharged from B.
*D. Electrical appliance that require the consumption of electrical energy.

The iteration:
1. When the component B is detected to be empty, then component A switch the electrical energy source from capacitor to external supply.
2. The electrical energy from external supply enter the component B via D until B is fully charged.
3. Component A switch the supply from external to internal.
4. Component B is then discharging through component C to component D. Thus component B is emptied.

Theoretically, since we use electrical energy from external source half of the time, therefore we save about 50% of electrical energy without affecting the operation of electrical appliances at all. However, since we require electrical energy to operate this invention, therefore we presume it is less efficient, thus we expect we could save 40% of electrical energy. The technical challenge is we need an capacitor that is capable of storing Million Joule of electrical energy, I believe it is easier to do that in a city as a whole than implemented by individual household.
