The impact of wind power plants on the environment, especially on birds, is indeed the most significant, but it does not mean that the existence of wind power plants will cause birds to be infertile, but will crowd out and Angering birds that can't live in this environment and migrate elsewhere is why birds are becoming extinct where wind turbines are being built. Wind energy is a "clean energy" in people's eyes and basically does not pollute the environment. However, the rotation of giant wind turbine blades has an impact on the local ecological environment.
Each one has its own advantages and disadvantages related to fire, hydro and wind power generation, solar and nuclear energy and energy utilization. Some environmental impact substances produced by the combustion process are environmentally friendly energy sources. It can be recycled and has no significant impact on the environment, but the impact on the ecosystem is huge. Especially the fish in the water. A hydropower station that has an impact on water ecology is tantamount to the isolation of the upper and lower ends. Many fish must return to their offspring. However, due to the rupture of the dam, they cannot return normally, which ultimately leads to considerable consequences. The hydropower station actually has It's two-sided, but it's a very real problem just because profit does more harm than good.
These operations can be performed remotely and automatically, so their impact is increasingly smaller. In general, wind energy has a certain impact on environmental ecology, but it does not have a significant impact, and from a broader perspective, renewable resources such as wind energy and electricity are more environmentally friendly and beneficial to the environment. Personal opinions are for reference only. Please criticize and correct any mistakes. Comparatively speaking, the scarecrow fan is a frighteningly ugly faker, not only the image, but also the scary thing is that they keep screaming and waving three hands non-stop! The wind can easily attack purity. So think about it: As long as humans build their own virtues, they don't have to worry about the fertility of birds because they have wings and stay away from giants to further their romance. The service life is about 20 years. 20 years is enough time to make the surrounding environment. Change is happening. Some reports mention this. Specific parameters and noise decibels. There is no concrete scientific evidence. In particular, it causes environmental damage.
Fan principle, however, in order to have a certain strength, the closer to the root of the fan blade, the thicker it becomes. Made of fiberglass. The reinforcing ribs made of fiberglass are placed in the mold and then injected with resin to form. The small air leaf has a solid structure, and the large one has a hollow structure. The hollow part of the large fan blade is almost half a cylinder. It is not an exaggeration to say that it is based on the principle of an airfoil. The installation angle of the fan blades is generally adjustable. The wind turbine has a complete constant speed device, and a device that automatically brakes, then turns, and finally rotates again when the wind direction changes. Don't do your own research and development. If you want to make a finished product for sale, just buy one and then reverse engineer it. You can search for "Manufacturing Process of FRP Fan Blades".
