To get an exact answer, you would have to specify a fusion reaction; different reactions will produce different amounts of energy. However, to get a rough idea, the energy produced is in the order of a million times more than the typical chemical reaction.
Nuclear power is produced through two processes: Nuclear Fission and Nuclear Fusion.
That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.
No, nuclear energy is not produced by sunlight. Nuclear energy is generated from the process of splitting atoms in a power plant, while sunlight produces solar energy through the fusion of hydrogen atoms in the sun.
No, they rely on fission. Controlled fusion is the holy grail of nuclear power.
Fusion power is the power generated by the nuclear fusion processes. Fusion power is a primary area of researc in plasma physics. For example, the sun is a natural fusion reactor.
Energy produced by nuclear power cannot be stored, it has to be used as soon as it is produced. This is done by producing steam from the thermal energy released and using this in a conventional power plant
No, a nuclear power plant producing electricity is an example of nuclear fission, not fusion. In nuclear fission, the nucleus of an atom is split, releasing energy, whereas in nuclear fusion, atomic nuclei combine to release energy.
Nuclear fusion
Sure, you can get a tan from it, since the Sun is a big fusion power reactor. In the near future we will be able to build fusion reactors here on Earth. Google "ITER" to see how it's going. In the meantime I suppose you can say the fusion power is actually solar energy.
Nuclear fusion is used only in experimental installations.
The only current application of fusion is in fusion-type nuclear weapons. We cannot control fusion to use it in power sources, so we are limited to just a single use or application.
Energy produced in the sun arises from nuclear fusion of hydrogen nuclei, whilst nuclear energy used in power plants comes from fission of uranium nuclei. They are very different.
