South Africa's Verreaux eagle is in trouble. their favorite landscape which the winds along the vast ridge carried them as they soared. It is an important place for wind farm developers. which want to use the same resources in all respects At least 24 corpses were collected under wind turbines," said Dr Megan Mercatroy of Hawkwatch International. It seems quite controversial.Birds sometimes die when they collide with fast-rotating turbine blades. which is difficult to see Or they were electrocuted by the wires at the wind farm.Dr Murgatroyd is on a mission to stop this. And she decided to work with wind power companies to find ways to reduce deaths.

Wind power on and offshore is ดาวน์โหลด slotxo ios gathering momentum around the world. in May The International Energy Agency announced that the amount of wind power added globally in 2020 is 114 GW, almost doubling in 2019.But many worry that insufficient action is being taken to prevent the death of thousands of animals. Although the rise of renewable energy is generally seen as good news in the fight against climate change This was underlined a few days ago. When the bearded vulture which was released into the wild last year in the south of France Killed by a windmill after it moved north into the Netherlands.

To help Dr Murgatroyd and her colleagues devised a commercial tool that tells developers in which areas Verreaux's eagles are most likely to fly. for companies Wind turbines can be placed away from those places.It was based on tracking data she collected after installing GPS devices on more than a dozen eagles. This tool also needs to consider where the nest is. Therefore, these planning surveys must be carried out in and around the space allocated for new wind turbines To try and verify the tool's recommendations, Dr Murgatroyd used it to analyze the location of the wind turbines that were built before the technology became available.

This revealed that many of the eagle deaths associated with those turbines occurred in places where models would rightly identify as high-risk.If using this model would be able to avoid 79% of [those deaths].Not all South African wind farm developers use this software. But she hopes wind farm developers will record fewer bird deaths on their property. She also plans to expand the technology to be able to assess the risks facing other bird species, including vultures. critically endangered black Estimates of the number of bird or bat deaths caused by wind turbines each year vary. Although there are definitely thousands of them. if not more As in 2019, scientific studies show that fossil fuels are associated with more animal mortality. Domestic cats are also highly toxic.

However, among those who think the impact of spinning blades should not be overlooked is Dr Christian Voigt of the Leibniz Institute for Zoo and Wildlife Research in Berlin.He occasionally visits the wind farm to see if there are dead bats on the ground.Actually, I find corpses quite often," he said. "That tells me there's something wrong here.Dr Voigt and his colleagues studied the effectiveness of existing technologies used to monitor the presence of bats in wind farms. This is usually done by placing a single microphone facing down at the center where the turbine blades meet.In Germany, surveys that detect bats in this way are used to create weather conditions related to bat activity around them.

The turbine is newly created. In this way, the turbine can be stopped - cut off - when the same conditions occur in the future. to protect bats that may enter But the method could be fundamentally flawed, Dr Voigt said. It turns out that individual microphones, which pick up the bat's ultrasonic calls, were not able to detect life as comprehensively as hoped. Some bats have ultra-quiet, high-frequency calls that are not very distant.Dr Voigt estimates that, on average, each wind turbine kills about 10 bats every year.There is a clash between protecting biodiversity and protecting the climate," he said. Environmental protection industry organization Wind Europe said.
