Fusion and fission nuclear reactions.
Nuclear reactions.
Nuclear reactions like nuclear power plants ^_~
If we are able control the fusion reactions then nuclear energy is the most preffered form of energy otherwise solar energy is prefferable.
I guess that would be when a "regular" particle meets an antiparticle - in that case, 100% of the mass of both particles will be released as energy.Next come nuclear reactions, where usually something like a fraction of one percent of the matter gets released as energy. Chemical reactions release about a million times less energy than nuclear reactions.
Yes, but if used properly nuclear fuels can provide energy for millions of years before running out, while all known fossil fuels will run out in at most a couple hundred years.

A fission reaction is a chemical reaction wherein the atom gets split to generate energy. The most commonly used controlled form of this is in splitting Hydrogen for producing energy in nuclear reactors. It is also used in weaponry such as Hydrogen Bombs which have much greater power than in nuclear fusion reactions.
Nuclear energy is not gathered or created. There is a saying to go along with this: Energy cannot be created or destroyed, only changed in form. That saying is called the Law of the Conservation of Energy. Nuclear is a type of potential energy so this concept applies to it. There are many ways nuclear energy can be used. Lets say submarines. Most people have heard of the nuclear powered submarines. They can stay under water for a long time because they have basically unlimited energy. The submarines are powered by a nuclear reactor causing a series of nuclear reactions. The submarine uses the nuclear reactions as power. Generally it will get converted to mechanical or electrical energy (both types of Kinetic energy).

There are several way to create electricity from nuclear energy. The most common way is to generate heat from the controlled fission of 235U, releasing binding energy, using that to heat water to steam, and using the steam to spin turbines that drive generators.
Nuclear reactions involve the reaction of nuclei and does not involve transfer of electron as in regular chemical reactions.
The most common fuels used in nuclear chain reactions are 235U (uranium) and 239Pu (plutonium).
Those most at risk in a nuclear energy accident are the workers at the nuclear facility itself.
No. Most of the energy resources used to generate electricity are non-renewable, like the burning of coal, oil and natural gas. Hydro power and nuclear power are the only important renewable sources. Wind and solar are not yet valid sources of power.
