Thus, it can be calculated that the energy obtained by the earth can reach 173,000TW. The standard peak intensity at sea level is 1kw/㎡, and the annual average radiation intensity at a 1.24 h on the earth's surface is 0.20kw/㎡, which is equivalent to 102,000TW of energy on which human beings depend for survival, including all other forms of renewable energy (except geothermal energy resources).

At present, the use of solar energy is not very popular, the use of solar power generation still has the problem of high cost and low conversion efficiency, but solar cells have been applied in providing energy for artificial satellites. Solar energy is the energy generated by the continuous nuclear fusion reaction process of sunspots inside or on the surface of the sun. The average solar radiation intensity in Earth orbit is 1,369w/㎡. The circumference of the earth's equator is 40,000km, so it can be calculated that the energy obtained by the earth can reach 173,000TW. The standard peak intensity at sea level is 1kw/㎡, and the annual average radiation intensity of a certain 1.24 h on the earth's surface is 0.20kw/㎡, which is equivalent to 102,000TW of energy. Human beings rely on these energy to survive, including all other forms of renewable energy (except geothermal energy resources). Although the total amount of solar energy resources is more than 10,000 times of the energy used by human beings, the energy density of solar energy is low, and it varies from place to place and from time to time, which is the main problem facing the development and utilization of solar energy. These characteristics of solar energy will make it clear that the role of solar engineering drawings in the entire integrated energy system is subject to certain restrictions. Although the energy radiated by the sun to the earth's atmosphere is only one 2.2 billion of its total radiation energy, it is as high as 173,000TW, that is to say, the energy radiated by the sun to the earth per second is equivalent to 5 million tons of coal, and the energy radiated to the earth per second is 499,400,00,000 joules. The wind energy, water energy, ocean temperature difference energy, wave energy and biomass energy on the earth all come from the sun; even the fossil fuels on the earth (such as coal, oil, natural gas, etc.) are fundamentally stored since ancient times. Solar energy, so the broad sense of solar energy covers a very large range, and the narrow sense of solar energy is limited to the direct conversion of solar radiation energy, photoelectricity and photochemistry. [2] Solar energy is both primary and renewable energy. It is rich in resources, can be used free of charge, and without transportation, without any pollution to the environment. For mankind to create a new form of life, so that society and mankind into an era of energy conservation and pollution reduction.
