The only way energy can travel without a medium is by electromagnetic waves, or in other words, photons.

A wave of kinetic energy requires a medium to travel though.

All waves can travel from one place to another as long as they have a medium to travel through. The only waves that do not need a medium are electromagnetic waves. When using the word "transfer" though. Waves transfer energy; waves themselves are not transfered they simply travel.

No, energy will transfer between any adjacent bodies, moreover, a medium is not necessary for energy to transfer between objects at all. That would be a little thing called radiation.

Transferring energy through empty space is called radiation. There are three types of energy transfer: conduction, convection, and radiation. Radiation is the only energy transfer that does not require a medium. Radiation is a wave of pure energy; one example of radiation is the sunlight that reaches Earth, which is electromagnetic radiation.
Radiation
Radiation.Conduction requires contact and convection requires a motive fluid. Radiation only needs a straight line of sight with no intervening medium.
Yes. Conduction involves the transfer of thermal energy without any movement of the material medium. For example, when one end of a metal rod is heated, the atoms at that end of the red vibrate more vigorously (gain kinetic energy), and they will collide with the neighbouring less energetic atoms and transfer its kinetic energy them and so on. Without these particles, thermal energy cannot be tranferred through conduction. The only form of thermal energy transfer which does not require a material medium (i.e., the atoms and molecules) is infrared radiation.
Radiation is the only method of energy transfer that can transfer energy like heat through space.
