Nuclear energy is converted into other energy sources (electricity, thermal energy, etc.) by nuclear combustion or nuclear fusion.
Solar energy is light and heat released by nuclear combustion, then converted into other energy sources. energy sources (electrical energy, thermal energy, etc.).
Although both have the same source, the energy conversion is different at a certain stage.
I hope this can help you^@^
< h3>Does all the energy on earth come from the sun? So nuclear fuel also comes from the sunNo. Nuclear power plants are new power plants that use the energy contained in atomic nuclei to produce electricity on a large scale. It can be roughly divided into two parts: one is a nuclear island that uses nuclear energy to produce steam, including nuclear reactors and de primary loop; the other is a conventional island that uses steam to generate electricity, including a turbine-generator system. This last part looks a lot like a regular thermal power plant, while the first part is completely different.
The fuel used in nuclear power plants is called “nuclear fuel”. Nuclear fuel contains the fissile substance uranium-235. A million-kilowatt nuclear power plant only needs to replenish about 30 tons of nuclear fuel each year, while a coal-fired plant of the same size burns 3 million tons of coal each year.
Currently, the world's most technologically mature nuclear island designs primarily use pressurized water reactors. The Daya Bay Nuclear Power Plant and the Ling'ao Nuclear Power Plant are both pressurized water reactors. Nuclear energyre is clean energy.
Most of the energy on Earth comes from the sun, but not all. Nuclear energy fundamentally is not.
Fossil energy on earth, such as coal, oil, natural gas, etc., was converted by organisms in ancient times using solar energy through geological processes, and can be considered to come from the sun indirectly. Wind power, water power, tidal power, etc. are also related to the sun and can also be considered to originate from the sun. Not to mention biomass energy, which comes directly from the sun.
But nuclear energy fundamentally is not. Nuclear power existed before the formation of the Earth (before the formation of the solar system). It was formed by the supernova explosion of the previous generation (or generations) of stars in the Milky Way. AprAs soon as the supernova exploded, it was dispersed. in the universe and then condensed in the interstellar gas clouds in Asia and Europe preserved on the planets during the formation of the solar system. Nuclear energy exists not only on Earth, but also on other planets and on the Sun.
Nuclear energy has basically nothing to do with the sun. This is basically irrelevant because nuclear fuels are divided into nuclear fusion fuels (hydrogen, helium and their isotopes) and nuclear fission fuels (uranium, thorium, plutonium, etc. and their isotopes). Among them, hydrogen, uranium, thorium, plutonium, etc. have nothing to do with the sun, and most helium has nothing to do with the sun. There is only one isotope of helium, helium-3, which comes from the nuclear fusion reaction on the sun. However, there is very little helium 3 on earth and has practically nono extraction and use value. Only helium 3 on the moon has it. use value, but there is currently no way to extract and use.
So, under current circumstances, it is correct that nuclear fuel on earth does not come from the sun. In other words, all energy on earth, except nuclear energy, comes from the sun.
