Supernova explosions happen with the most massive of stars > 20 of our Suns.

The energy output of a supernova explosion is equivalent to the energy produced by the sun over its entire lifetime.
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
A supernova can produce as much energy in a few seconds as our sun will in its entire lifetime.
Elements such as gold, silver, and uranium are typically remnants of a supernova explosion. These heavy elements are formed during the intense energy release of a supernova event.
The very large nucleus of the uranium atom is a kind of energy storage unit. The energy of that nucleus is the result of the nuclear synthesis reactions that take place in a supernova. In that sense, a supernova is the energy source of uranium.
A supernova can be massive but some aren't. Every supernova is a dieing star. Supernovae are exploding stars. They represent the very final stages of evolution for some stars. Supernovae, as celestial events, are huge releases of tremendous energy, as the star ceases to exist, with about 1020 times as much energy produced in the supernova explosion as our Sun releases every second.
A supernova is not a celestial body in itself, but rather an astronomical event where a star suddenly increases greatly in brightness due to an explosive burst of energy. It is the result of the death of a massive star.
Not sure what you mean. For a few days, a supernova shines as bright as an entire galaxy - that is, roughly as bright as 100 billion stars.
During a supernova explosion, high-energy processes, such as fusion and neutron capture, occur, leading to the creation of elements heavier than iron, including carbon. These processes involve enormous amounts of energy and pressure, causing lighter elements to fuse into heavier ones. This is how carbon is produced in supernova explosions.
A safe distance from a supernova explosion would be millions of light-years away. The energy and radiation emitted during a supernova event are extremely powerful and can have destructive effects on planets and other celestial bodies nearby.
The ultimate source of energy on the Earth comes from the Sun, and gives us coal, oil etc. And of course, our weather and warmth. The fissile sources of energy such as uranium and plutonium originated in the explosion of a supernova. And may have arrived in the Solar dust cloud via debris of some earlier planet. Of course, there is some kinetic energy left over from the formation of our Galaxy, Solar system, and Earth, and gives us the movements and rotation of these bodies and systems.
