When a potential difference $\displaystyle V$ is applied across a wire of resistance $\displaystyle R$, it dissipates energy at a rate $\displaystyle W$. If the wire is cut into two halves and these halves are connected mutually parallel across the same supply, the energy dissipation rate will become:
