Closing and opening energy storage capacitor

Why does the switch store energy after closing? | NenPower

Capacitors function by accumulating electrical charge when a voltage is applied, creating an electric field that enables energy storage. The amount of energy a capacitor can hold is defined by its capacitance value, which is measured in Farads. As the switch closes, the circuit reaches a steady-state where the current flows consistently.
