What's happening inside the sun is (nuclear fusion) releasing enormous amounts (of nuclear energy). Therefore, the sun has enormous energy.
The use of solar energy is: (solar battery) and (solar water heater)
What it is acts on the conversion of energy or the transfer of energy, they all have a direction; not all energy can be used. There are (conditions) and (costs) for using energy
Solar energy comes from nuclear fusion.
1. Solar energy is generated by the fusion of hydrogen and helium inside the sun to release enormous nuclear energy. Most of the energy needed by humans comes directly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide and convert solar energy into chemical energy and store it in the plant body through photosynthesise.
2. Fossil fuels such as coal, oil, and natural gas are also primary energy sources formed by the evolution of ancient animals and plants buried underground over a long geological period. The energy contained in the earth itself generally refers to the energy related to the thermal energy inside the earth and the energy related to the nuclear reaction.
3. The energy linked to nuclear reactions is nuclear energy. When the structure of the atomic nucleus changes, it can release a large amount of energy, called nuclear energy, or nuclear energy for short, commonly known as atomic energy. It comes from nuclear fission energy resources when uranium, plutonium, etc. are produced. stored in the earth's crust undergo fission reactions, and nuclear fusion energy resources when deuterium, tritium, lithium, etc. stored in the ocean undergo remerger actions.
4. Solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun. The average intensity of solar radiation in Earth's orbit is 1369 W/㎡. The equatorial circumference of the Earth is 40,076 kilometers, so it can be calculated that the energy obtained by the Earth can reach 173,000 TW.
