In recent years, wind energy as a source of renewable and clear energy has become increasingly popular. Unfortunately, wind energy has one significant environmental drawback: fast-moving turbine blades .pose serious threats to birds flying through wind farms. Various strategies are now being considered to make wind farm turbines safer for birds.
Radar
One method involves installing radar devices in wind turbines. The purpose of the radar devices is to scan the landscape and detect when groups of birds are approaching the wind farm. Once the devices identify the birds on the horizon, they capture images of the landscape and notify wind farm operators. After examining the radar images, the wind farm operators can temporarily shut down the wind turbines to allow the birds to fly safely through the wind farm.
Purple paint
Another option is to paint wind turbines purple. The conventional colors of wind turbines are white and gray. These colors are usually used so that the turbines blend into the background. However, these colors also attract insects. A high concentration of insects, in turn, draws in birds that prey on the insects. Scientists have recently reported that purple is the least attractive color for insects Therefore. if wind turbines are painted purple, they will attract fewer insects, and fewer birds will come close to the turbine blades
Sound alarm
A third way is concerned with using a sound alarm system to warn birds of wind turbines in front of them. While flying, most birds look to the side and down, as their eyes are located on the sides of their heads and their bodies are in a horizontal position. The sound projected by the wind farm would alert birds. and it is believed that it would make them look ahead and fly slower or stop flying completely. The sound alarm systems would likely save birds from the danger posed by wind turbines.
The passage discusses the popularity of turbines as a source of renewable source of energy but they pose a serious threat to birds, and then puts forward several solutions to address them. However, the speaker casts doubt on all of them by presenting some rational counterarguments.
First and foremost, The article asserts that putting in place some radars capable of detecting birds that turn off turbines will save birds. On the other hand, the professor pointed out that the process of turning off a turbine takes 45 minutes, thereafter birds will hit turbines before a complete shutdown. Moreover, these radars are not able to detect single birds at all. Therefore, radars are not reliable.
Secondly, The writer contends that scientists have proved the common color of turbines. gary and white, attract insects that catch the birds' attention so as to printing them in purple will be effective. The speaker, conversely, calls this into question. She states that both heat and ultraviolet are responsible for attracting insects. As a result, solely will changing the color not keep away birds.
Last but not least, The author claims that birds while flying look at their sides so if we produce sound to force them to look forward, they will change their direction to avoid hitting turbines. On the contrary, the lecture clears out that due to noises such as vihechles', a strong and unique voice is needed, and indeed it will disrupt the neighboring areas. As such, this solution is not practical.
