Wind power certainly has the advantage of being clean, but the main differences between wind power and coal power are: 1. The investment in wind units is much greater, but the effective annual hours of electricity generation are much less (coal power can generate more than 6,000 hours, while wind power can generate more than 3,000 hours) (difficulty). 2. Wind power will lose power suddenly when there is no wind, while coal power is quite stable and safe. 3. The cost of wind power is high, and ordinary people are not convinced by the high price of clean electricity. The government needs subsidies, but the cost of coal power is low and ordinary people at the bottom rung of society can accept it. 4. In terms of operational security of large power grids, if the proportion of wind energy is toop important, it will easily cause oscillations or even collapse of the power grid system, while coal power is very safe for the power grid. Wind energy is therefore one of the future development directions, but it still has obvious technical shortcomings (connected to the grid) and high costs.
1284 hours. Official information from Qinghai Province shows that the average hours of wind power usage in 2021 is 1,284 hours. Qinghai, called "Qing", is a provincial-level administrative region of the People's Republic of China, whose provincial capital is the city of Xining. It is located inland in northwest China, bordering Gansu to the north and east, Xinjiang to northwest China. in the northwest, Tibet in the south and southwest, and Tibet in the southeast. Bordering Sichuan, it is located in the northwest region ofs four main geographic divisions.
