?I already wondered what it was. After all, I was quite curious when I saw a small fan spinning on a telephone pole. So I asked my brother, who was older than me at the time.
?He told me it was used to produce wind power. Actually, I heard about wind power generation a long time ago. Energy saving and new energy are now more popular. Solar power and wind power are relatively clean energy sources that we currently have.
?In fact, clean means that there is no pollution. According to my observation, when I took the 212 to school, I found that there were many street lights on the road near the school, and there was something like a small fan on each of these street lamps. It has three leaves and there is a solar panel in its lower part. Sometimes it keeps turning, et sometimes he stays there quietly.
? We are located in the middle of the Yangtze River and there are no other buildings around our school except our school. The wind here is still relatively strong. There is also a lot of sunshine, so the street lights are on every day and the brightness is pretty good, except for rainy days.
? When I didn't know it before, I thought it was a decoration. When I went to Shandong before, I saw a wind power generation base somewhere.
?There is a relatively large fan-shaped object about one or five meters away. It's the same as the one on the telephone pole, but it's bigger than the one on the telephone pole. in the car at the time. Yes, I saw the three big leaves whirring and turning. Around this time, I learned for the first time that wind power uses fan-like blades that spin and whir.
? Donc, I am now quite sure that the fan shaped object on the telephone pole is used to generate wind power and convert wind power.
