Solar energy is energy from the celestial bodies outside the Earth (mainly the sun). Most of the energy required by humans comes directly or indirectly from the sun. It is the various plants that convert solar energy into chemical energy through photosynthesis and store it in plants. Fossil fuels such as coal, oil and natural gas are also formed by ancient plants and animals buried in the earth for a long period of geological time. They are essentially solar energy fixed by ancient creatures. In addition, water energy, wind energy, etc. are also converted from solar energy. Sinoma's solar power system The energy inherent in the Earth itself usually refers to the energy associated with the heat inside the Earth and the energy associated with the nuclear reaction. The energy associated with nuclear reactions is nuclear energy. When the structure of the nucleus changes, it can release a lot of energy, called nuclear energy, referred to as nuclear energy, commonly known as atomic energy. It comes from the nuclear fission energy resources in the fission reaction of uranium and thorium stored in the earth's crust, and the nuclear fusion energy resources in the fusion reaction of thorium, thorium and lithium stored in the ocean. These substances release energy when a nuclear reaction occurs. The biggest use of nuclear energy today is power generation. In addition, it can also be used as other types of power sources, heat sources, and the like. The world's tidal energy can be converted into coal by about 3 billion tons per year, and what is actually available is only the part of the shallow sea area, which can be converted into 60 million tons of coal per year. Solar energy is a huge energy released by the fusion of hydrogen nuclei at ultra-high temperatures. Solar energy is a treasure house of human energy. For example, fossil energy, wind energy on the earth, and biomass energy are all derived from the sun. The basic methods of solar energy utilization can be divided into the following four categories. Indirect use of solar energy: fossil energy (light energy - chemical energy) biomass energy (light energy - chemical power) Direct use of solar energy: collectors (with flat-plate collectors, concentrating collectors) (light energy – internal energy) solar cells: (light energy –---electric energy) is generally applied in man-made Satellites, spacecraft, lighters, watches, etc. Food Flower Temperature data logger Temperature Data Logger With Lcd,Flower Temperature Data Logger,Flower Temperature Data Recorder,Food Temperature Data Logger Chengdu Augus Science Technology Co., Ltd. , http://www.vluckyaugus.com
