The energy changes from potential to kinetic. All of the energy is in the potential when the pendulum is at its highest point and not moving. The pendulum then starts to move and the energy is shifted into kinetic energy. The kinetic energy is greatest at the bottom of the swing and the amount of energy is equal to the maximum potential energy.
