Answer:

Entropy is the reason of worrying about world energy sources.

Step-by-step explanation:

  • Entropy is the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
  • The amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
  • For example , There are some reactions which are irreversible because some of the energy in the reaction is lost to environment instead of converting totally to the products.
  • This lost of energy is entropy.
  • Due to which the energy of universe is losing irreversibly.
  • That's why we worry about world energy sources.
