Solar energy is an emerging renewable energy source and a relatively good source of energy.
Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of thermal energy: radiation). Its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has relied primarily on thermal radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as crafting. salt and dry the salted fish. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways toUsing solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
Solar energy is generated by the fusion of hydrogen and helium inside the sun to release enormous nuclear energy. This is the energy of solar radiation. Solar Energy System Most of the energy humans need comes from the sun, directly or indirectly. Plants release oxygen, absorb carbon dioxide and convert solar energy into chemical energy and store it in the plant body through photosynthesis. Fossil fuels such as coal, oil and natural gas are also primary energy sources formed by the evolution of ancient plants and animals buried beneath.s earth over a long geological period. The energy contained in the earth itself generally refers to the energy related to the thermal energy inside the earth and the energy related to the nuclear reaction.
