SPEAKING Enquiry Mass-energy transfer from one acting (inertial) system (mass-energy source) to another reacting system (mass energy sink or load) ... during the systems' forced-displacement interaction (mass-energy transfer), the material structure of the mass-energy sink system (e.g., a resisting, ultimately 'dissipating' load) is accelerating on the expense of decelerating material structure of an acting source system (effectively 'pumping' electromagnetic mass-energy from the source to sink system).

Energy transfer is a forced-displacement interaction between inertial material systems, in effect, accelerating the reacting, mass-energy sink-system (i.e. its structure) at the expense of decelerating an acting-source system structure, by propagating (“pumping”) the electromagnetic photon mass-energy from the source to the sink system, as explained elsewhere for the thermo-mechanical energy transfer (see note below). This is true in general, even in steady-state processes (which are transient from inlet to outlet), the surrounding 'supporting' system structure is reacting with its inertia as “ultimate frictional resistance load” and being accelerated (i.e. energized) all the time; otherwise without reacting (impeding) system, the potential-source system will not transfer any mass-energy and will continue to be in its inertial motion (if any) with its 'rested' equilibrium mass-energy structure.
NOTE 1: In phenomenological Thermodynamics, the Mother of all sciences (“integral check-an-balance” mass-energy science), the intrinsic energy is defined as a material property (contained or “bound” within material system), and energy transfer from system to system is accomplished via heat-transfer and/or work-transfer. Actually, electromagnetic radiation is energy in-transfer, either with controlled frequency and/or direction (radio waves, laser light, work transfer), or as “diffuse” thermal radiation spectra on-distance or on-contact (radiation or conduction heat transfer, respectively).
NOTE 2: The existence in space and transformations in time are manifestations of perpetual mass-energy forced displacement processes: with net-zero mass-energy transfer in equilibrium (equilibrium process) and non-zero mass-energy transfer in non-equilibrium (active process) towards equilibrium.
