The solar energy is the energy from celestial bodies outside the earth (mainly solar energy), which is the huge energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperature.
Almost all of the Earth's energy input comes from the sun. Not all of the sunlight that strikes the top of the atmosphere is converted into energy at the surface of the Earth. The Solar energy to the Earth refers to this energy that hits the surface of the Earth itself. The amount of energy that reaches the the Earth provides a useful understanding of the energy for the Earth as a system. This energy goes towards weather, keeping the temperature of the Earth at a suitable level for life, and powers the entire biosphere. Additionally, this solar energy can be used for solar power either with solar thermal power plants or photovoltaic cells.
Most of the energy needed by human beings comes from the sun directly or indirectly. The fossil fuels such as coal, oil and natural gas that we need for life are all formed by plants that convert solar energy into chemical energy through photosynthesis, which is stored in plants and then formed by plants and animals buried in the ground through long geological ages. In addition, water energy, wind energy, wave energy, ocean current energy, etc. are also converted from solar energy.
