What do you mean by degradation of energy? Explain it by taking two examples of your daily life.



The gradual decrease of useful energy due to radiation loss, friction, etc. is called degradation of energy.

Examples of degradation of energy —

  1. In transmission of electricity from a power generating station, a lot of electrical energy is wasted in the form of heat energy in the line wires used for transmission.
  2. When we cook food over a fire, the major part of heat energy obtained from the fuel is radiated out in the atmosphere. This radiated energy is of no use to us. It is thus a degraded form of energy.
