Energy transport can be done in three ways:
All three kinds of energy transport happen when you heat a pan of soup on a fire. The hot gases from the fire go up because of convection. The fire produces heat radiation, which you can block with your hand. The outside bottom of the pan is heated and conduction makes the heat reach the inside bottom of the pan, where it heats the soup. At first, the heat travels up the soup only by conduction, but later (when the soup is boiling) also by conduction.
