As usual, XKCD provides some help to understand how much energy a supernova is:
"Which of the following would be brighter, in terms of the amount of energy delivered to your retina:
1. A supernova, seen from as far away as the Sun is from the Earth, or
2. The detonation of a hydrogen bomb pressed against your eyeball?
Answer: the supernova, by nine orders of magnitude."
