The energy stored in the two capacitors is less than the energy that was originally stored in (text{C}_1). What has happened to the lost energy? A perfectly reasonable and not incorrect answer is that it has been dissipated as heat in the connecting wires as current flowed from one capacitor to the other.

Energy dissipated across a resistor when charging a capacitor
When a capacitor is charged from zero to some final voltage by the use of a voltage source, the above energy loss occurs in the resistive part of the circuit, and for this reason the voltage source then has to provide both the energy finally stored in the capacitor and also the energy lost by dissipation during the charging process.
