There are two types of waves that can transmit energy through a vacuum: electromagnetic waves and gravitational waves.
Electromagnetic waves are waves that are created by the oscillation of electric and magnetic fields. These waves can travel through a vacuum because they do not require a medium to propagate.
Gravitational waves are waves that are created by the oscillation of mass. These waves can also travel through a vacuum because they do not require a medium to propagate.
