An essay on a small invention that uses wind as energy (100 ~ 150 words)

The wind turbine looks like a large windmill, it is silver gray. Each of these large windmills is about forty or fifty meters high, and it would take five or six people to hold them together. At the top of the wind turbine is a three-blade rotating turbine. The wheel doesn't spin very fast, and even if it does, the three blades are clearly visible. The center of the turbine is the generator and the wind turbine is shrouded inside so we can't see it. When we looked, there were almost no large windmills that weren't spinning. Even though the wind was very light, they were still turning. When the windmill spins, the whole windmill makes a sound. Listening next to the big windmill, my ears were almost numb.
