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 suddenly lose power 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.
No.
The main reasons are:
It’s hard to absorb. Nowadays, many wind power areas with good wind resources are located in relatively remote places, such as Xinjiang, Inner Mongolia, Gansu and other sparsely populated places. The electricity produced cannot be consumed locally and the current construction of the electricity grid cannot keep pace. There is no way to transport electricity to more distant locations. This is now called the electricity curtailment problem. Islandst very serious and directly eliminated many sources of electricity. generation businesses profit.
Quality issues. The rapid reduction in wind energy costs actually comes largely at the expense of unit quality. Currently, many wind turbines have high failure rates, high maintenance costs and low power generation efficiency.
The national subsidy policy is gradually reduced. Wind power is currently a relatively mature technology among new energy sources, but there are reports that compensation for wind power will be reduced, which could worsen the current recession.
