Question: What should I do if I find that the windmill on the mountain has broken wings?
Answer: If I find that the windmill on the mountain has broken wings, it should be repaired. Because the large windmill on the mountain is used for wind power generation, if it breaks down, it may affect the wind power generation in the area.
Analysis: The large windmill on the mountain is also called a wind turbine. Its function is to convert the kinetic energy of the wind into mechanical energy. This mechanical energy drives the generator to generate electricity, thereby converting it into electrical energy.
