The present invention relates to a plasma display apparatus including an energy recovery circuit capable of maximizing driving efficiency, and driving method thereof. The plasma display apparatus of the present invention includes a plasma display panel having an electrode, an energy supply and recovery unit for dividing a source voltage source to supply the energy of a first voltage higher than a reference voltage and to supply the energy of a second voltage lower than the reference voltage, a path select controller for establishing a path so that the energy of the first voltage is supplied to the electrode through resonance and establishing a path so that the energy of the second voltage is recovered from the electrode through resonance, and a voltage sustain unit for applying a third voltage to the electrode after the energy of the first voltage has been supplied to the electrode through resonance and applying a fourth voltage to the electrode after the energy of the second voltage has been recovered from the electrode through resonance. According to the present invention, the energy supply and recovery unit supplies energy greater than the reference voltage and recovers energy lower than the reference voltage. Accordingly, driving efficiency can be improved.
