Some nuclei, notably U235 and Pu239, can be made to cause a chain reaction where neutrons are produced in nuclear fission, and propogate more subsequent neutrons so that a steady rate of fissions can be achieved. Each fission releases an amount of energy in the form of heat, which is then used in generating plant similar to that in a fossil fuelled power plant.
Release of excess binding energy as kinetic energy when very small nuclei fuse or very large nuclei fission or unstable nuclei decay to more stable ones.

Nuclear energy
Uranium is used as nuclear fuel in nuclear reactors.
We get most of our energy from the Sun; there, the energy is converted by nuclear fusion.On the other hand, technology is not yet ready to carry out nuclear fusion on our own, right here on Earth - except for some experiments.
Nuclear energy is a kind of potential energy.
Solar energy is formed by nuclear fusion in the sun
Nuclear and Geothermal
Energy hasn't been formed since the creation of matter. However, energy is present in atoms and can be released during chemical or nuclear reactions.
iron
Yes, and it is formed from the process called nuclear fusion. The sun's own energy comes from nuclear reactions taking place in the sun's core.
Nuclear is formed either by: Fission of heavy nucleiFusion of light nucleiRadioactive decay of unstable nucleiNuclear energy results from the mass defect (either due to fission, fusion, or radioactive decay) change into kinetic energy that is changed into thermal energy (producing steam) then to mechanical energy then to electric energy.
Energy is formed and released following destruction of mass, E=mc2
Uranium formed in supernova explosions. Hydrogen has been in the universe since milliseconds after the big bang.
The hydrogen in the Sun has nuclear energy (a type of potential energy). When this is fused, it is converted to heat energy. This eventually gets radiated out as light energy.
If it is stored in the nucleus, it must be nuclear energy.
The sun radiates energy through nuclear fusion. This causes helium atoms to be formed which then become excess energy that moves into space.
Humans did not create nuclear energy, it was created shortly after the big bang when the first stars formed and began fusing hydrogen into helium. Later supernova explosions created elements up to uranium, which we can use as fuel in nuclear reactors and nuclear bombs.
