Wind energy is one of the most powerful forms of energy used in the world today, as is evident worldwide. According to the latest statistics, the world generated approximately 1000 gigawatts of wind energy in 2024 AD, making the importance of wind energy use all over the world clear. One of the problems associated with the use of wind turbine farms is the noise generated by the rotation of the blades. Reducing this noise is essential for smooth energy use. In this paper, we present a study on how to reduce the noise generated by these turbines by conducting scientific experiments to replace the material used in wind turbine blades. Instead of using carbon Fiber, we used Plexiglass and Iron Nickel Chromium. We conducted experiments to determine the feasibility of using these materials to reduce the noise generated by wind turbines, and the results were impressive. When using Iron Nickel Chromium in a 100-watt wind turbine, we found that the noise was reduced from 90 dB to 75 dB at 70 RPM, and Plexiglass reduced the noise to 48 dB at the same speed compared to carbon Fiber. These results demonstrate the feasibility and importance of conducting research on this topic.

摘要

Wind energy is one of the most powerful forms of energy used in the world today, as is evident worldwide. According to the latest statistics, the world generated approximately 1000 gigawatts of wind energy in 2024 AD, making the importance of wind energy use all over the world clear. One of the problems associated with the use of wind turbine farms is the noise generated by the rotation of the blades. Reducing this noise is essential for smooth energy use. In this paper, we present a study on how to reduce the noise generated by these turbines by conducting scientific experiments to replace the material used in wind turbine blades. Instead of using carbon Fiber, we used Plexiglass and Iron Nickel Chromium. We conducted experiments to determine the feasibility of using these materials to reduce the noise generated by wind turbines, and the results were impressive. When using Iron Nickel Chromium in a 100-watt wind turbine, we found that the noise was reduced from 90 dB to 75 dB at 70 RPM, and Plexiglass reduced the noise to 48 dB at the same speed compared to carbon Fiber. These results demonstrate the feasibility and importance of conducting research on this topic.
