Solar energy is the energy of celestial bodies outside the earth (mainly solar energy). This is the enormous energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperatures. indirectly from the sun. Fossil fuels such as coal, oil and natural gas that we need to live are all formed by various plants which convert solar energy into chemical energy through photosynthesis and store it in plants, then by plants and animals buried underground for a long time. period of geological time. In addition, water energy, wind energy, wave energy, ocean current energy, etc. are also converted from solar energy.

Background
Energy Current situation
With the development of the economy and the progress of society, the People have put forward increasingly higher energy needs, and finding new energy has become an urgent problem facing humanity. There are four main existing sources of electrical energy, namely thermal energy, hydroelectricity, nuclear energy and wind energy.
Thermal energy must burn coal, oil and other fossil fuels. On the one hand, fossil fuel reserves are limited, and the more they are burned, the less they are, and risk being exhausted. On the other hand, combustion emitsra carbon dioxide and sulfur oxides, thus causing the greenhouse effect; and acid rain, which is damaging the global environment.
