A plasma display panel driving apparatus and method for applying a driving voltage to drive a plasma display panel, where the plasma display panel includes discharge cells formed where the X electrodes cross the Y electrodes is disclosed. The apparatus includes an X electrode driver for applying the driving voltages to the X electrodes and a Y electrode driver for applying the driving voltages to the Y electrodes. The X electrode driver comprises a first energy recovery unit collecting and accumulating charge from discharge cells and then providing the accumulated charge to the discharge cells, in the address period, and may include a second energy recovery unit collecting and accumulating charge from the discharge cells and then providing the accumulated charge to the discharge cells, in the sustain-discharge period.
