Solar ( Solar Energy ), generally refers to the solar radiation energy, commonly used for power generation in modern. Since the formation of the earth organism mainly to light and heat provided by the sun to survive, and ancient humans have learned to sun objects, but in the fossil fuel, it intends to further the development of solar energy. The use of solar energy has passive use ( conversion ) and photoelectric conversion in two ways. solar wafer is a renewable energy source. The solar energy on earth is a lot of energy sources, such as wind energy, chemical energy, water energy and so on.

Solar energy is the energy from Earth external objects ( mainly solar ) energy required for the vast majority of people are directly or indirectly from the sun. It is a variety of plants through photosynthesis, converting solar energy into chemical energy stored in plants. Coal, oil, natural gas and other fossil fuels is composed of ancient buried plants and animals through the long geological time form. They are essentially by ancient biological fixed solar. In addition, hydro, wind, wave, current can also be composed of solar energy conversion. The earth itself is usually with the energy of earth's internal heat related to energy and nuclear reaction energy.

And nuclear reaction energy is nuclear energy. The atomic structure is changed to release a lot of energy, called nuclear energy, referred to as nuclear energy, commonly known as the atomic energy. It comes from the crust of uranium, plutonium storage produce fission reaction when the nuclear fission energy resources, as well as deuterium, tritium storage in the ocean, such as lithium occurs when the fusion reaction of nuclear fusion energy resource. These substances in the event of nuclear reaction energy release. The current maximum is the use of nuclear power. In addition, can also be used for other types of power source, heat source.

The whole world tide can be folded about annual 30 tons of coal,company formation and the actual available only in shallow waters that part, each year approximately equivalent to 60000000 tons of coal. The basic way of solar energy utilization can be divided into the following 4 categories. Solar energy is the nucleus of the hydrogen atom in the ultra high temperature fusion release tremendous energy, solar energy is the human energy treasure, such as fossil energy, wind energy, biomass energy on the earth from the sun. The use of solar energy utilizing indirect solar: fossil the sources of energy ( solar energy, chemical energy of biomass energy ( energy ) - chemical energy )

Direct use of solar energy heat collector: ( flat type heat collector, condensing type heat collector ), ( solar energy, internal energy).

Solar cell: (light - electricity) are generally used in satellites, spacecraft, lighter, watches etc..
