which simplifies to:
Charge on capacitor remains the same while moving the plates. Capacitance value decreases as distance increases.
Since Q = CV, voltage V goes up in proportion to distance stored energy is not used up, and external force is used to move the plates. This external energy is stored in capacitor at the new voltage, the additional energy being in proportion to increase in distance.
