Solar energy is from outside the earth objects (mainly solar energy), is the sun in the nuclei of hydrogen atoms in ultra high temperature fusion massive release of energy, the energy required for the human most directly or indirectly from the sun. For we live in coal oil, natural gas and other fossil fuels are because of various plants to convert solar energy into chemical energy stored in plants down through photosynthesis by plants and animals buried in the underground after a long geological ages formation. In addition, water power, wind energy, wave energy, ocean current energy are also converted from the solar energy.
