Energy transfer

This article is about the physical process. For the energy company, see Energy Transfer Partners.

Energy transfer is the transfer of energy from one object or material to another.

There are a few main ways that energy transfer occurs:

• Radiant energy (radiation)
• Heat conduction (travelling heat)
• Convection (currents of warm air)
• Mass transfer (hot material transferred to another location)
• Electrical power transmission (wires carrying current)
• Mechanical work (machines)
