Solar Energy Definition

- Jun 14, 2015-

Solar energy is the energy produced by the fusion of internal hydrogen atoms to release huge amounts of nuclear energy, from the radiation of the sun。 Most of the energy that humans use comes directly or indirectly from the sun。 Plants release oxygen through photosynthesis, absorb carbon dioxide, and convert solar energy into chemical energy for storage in plants。 Fossil fuels, such as coal, oil and natural gas, are also derived from plants and animals buried in the ground in the ancient times through a long geological era and belong to primary energy sources。 The energy contained in the earth itself usually refers to the energy related to the heat energy inside the earth and the energy related to the nuclear reaction。 Nuclear energy is the energy source associated with nuclear reactions in the model of nuclear - internal structure。 When the structure of the nucleus changes, a large amount of energy can be released。 It comes from nuclear fission energy resources such as uranium and plutonium stored in the earth's crust during fission reactions, and nuclear fusion energy resources such as deuterium, tritium and lithium stored in the ocean during fusion reactions。 These materials release energy in the event of a nuclear reaction。 At present, the biggest use of nuclear energy is to generate electricity。 In addition, it can also be used as other types of power source, heat source, etc。
