discharge

If biased around DC, the capacitor stores energy as the voltage increases in magnitude (either positive or negative), and the capacitor gives up energy as the voltage returns to zero. Thus 1/4 cycle is store, 1/4 cycle is discharge, this occurring for each 1/2 cycle. If biased asymmetrically, then the timing changes.

simulation

The energy consumed is C·V² but, the energy stored is only ½ C·V². Consider a 1μF capacitor charged to 1 volt and then connected to a discharged 1μF capacitor. Charge (C·V) is conserved hence, the final voltage is 0.5 volts. For energy there is loss: -. • Initial energy: ½ × 1μF × (1 volt)² = 500 nJ.
