    Upper minus lower. The upper graph represents the energy absorbed by the wire to cause its extension l. The lower one represents the energy released by the wire to bring it back to its original position. But it doesn't return to its original position and the extra energy is stored as the wires...

    The elastic potential energy is the energy under the graph. You count the number if small squares and multiply it by the area of one small square to find out the energy. The wire will be permantly stretched/extended a little since some if the energy has been converted into its inter al energy...
