That depends on the type of wave. An electromagnetic wave can be transmitted through a vacuum.
Thermal power plantThe term for such a material is "medium". Thus the sound of talking is carried by the medium air. The ocean waves exist in the medium water. Light is carried by the medium space. The plural is media.
The more closely packed molecules are in a medium, the faster sound travels through the medium, so sound travels slowest through a gas under low pressure.
energy is independent of medium it passes through?
Convection takes place through a material medium between source and sink. There isn't any material medium between sun and earth, and we are therefore thankful that radiation exists.
Yes definitely. That too the medium has to be a material medium. Because sound is nothing but the longitudinal vibrations produced in the material medium. Hence the transfer of sound energy is nothing but the transfer of this vibrational energy through the material medium.
Medium.
Depends what you understand by "material medium". You certainly don't need any matter. Both electromagnetic waves and gravitational waves travel through empty space (and of course, both transmit energy).

The medium of any wave is the material that the wave energy travels through; in this case water.
They travel through a material medium.
The material through which a wave travels is called the medium.
