Answer:
Electricity
Explanations:
Energy transfer is the movement of energy from one point to another. This can be heat energy, kinetic energy, etc.
There are three forms of energy transfer, namely:
Conduction
Convection
Radiation
Conduction is the transfer of heat energy in which there is no actual movement of the molecules involved. This usually happens in solid materials
Convection is the transfer of energy in fluids. This involves the movement of the molecules through which the energy is transferred.
Radiation is the transfer of energy in which no material is involved.
Note that electricity only involves the movement of charges, it is not a mode of energy transfer.
