In the US, about 20 percent of total electicity. Worldwide it is about 16 percent
Nuclear fission is the method currently used for generating energy, while nuclear fusion is still being developed for practical use.
The only form of nuclear energy currently used in the US, or anywhere in the world for that matter, to produce electricity is nuclear fission. There are ongoing experiments to attempt to use nuclear fusion, but the technological problems with that have not paid off yet.
The amount of energy released in a nuclear reaction is so great because of the large amount of energy stored within the nucleus of an atom. When nuclear reactions occur, this energy is released in the form of radiation and kinetic energy due to changes in the nucleus, resulting in a significant amount of energy being released.
You are under a misapprehension about 'finding' nuclear energy. The uranium is found in a natural ore, mined and refined, and then made into nuclear fuel in the form of fuel rods. At this stage there is no nuclear energy being released, except for a small amount of natural radioactivity which is trivial. It is only in a nuclear reactor that a nuclear chain reaction is produced and energy is released because U-235 is being fissioned. This appears as heat in the fuel rods which is then used in a normal power plant steam cycle.
An example of chemical energy being converted to nuclear energy is a nuclear power plant. In a nuclear reactor, uranium atoms undergo nuclear fission, releasing a large amount of energy in the form of heat. This heat is then used to produce steam, which drives turbines to generate electricity.
Nuclear fission involves splitting a heavy nucleus into lighter elements, releasing energy. Nuclear fusion involves combining light nuclei to form heavier ones, also releasing energy. Fission is currently used in nuclear power plants, while fusion is still being developed as a potential future energy source.
Nuclear fission has been used in nuclear bombs and is currently being used in every nuclear power plant on the earth.
No. But old ones are being refurbished.
Two common sources of nuclear energy are nuclear fission, where atoms are split to release energy, and nuclear fusion, where atoms are combined to release energy. Nuclear power plants use nuclear fission to generate electricity, while nuclear fusion is a process being researched as a potential future source of clean energy.

Nuclear energy has the advantage of being a low-carbon energy source, producing significant amounts of electricity with minimal greenhouse gas emissions. It provides a reliable and consistent power supply since nuclear plants can operate continuously for long periods. Additionally, nuclear energy is an energy-dense source, meaning it can produce large amounts of electricity from a small amount of fuel.
Energy being released refers to the transformation of stored energy into a different form, such as heat, light, or sound. This release of energy occurs during various processes like chemical reactions, nuclear reactions, or mechanical work. The released energy can have a wide range of effects depending on the source and amount of energy involved.
