How much greater is the energy released by a Supernova compared to a Classical Nova?

Answer

By a factor of at least 10,000

There is a vast chasm in energy release between a classical nova and a supernova. A classical nova, stemming from surface hydrogen fusion on a white dwarf in a binary system, releases energy equivalent to perhaps 10,000 to 100,000 times the energy the Sun emits over an entire year. In contrast, supernovae involve the total destruction or complete core collapse of a star, making them intrinsically more violent. This difference means that a supernova releases energy that is greater by a minimum factor of 10,000 when compared directly to the energy yield of a classical nova event.
