Energy Devices Marine Renewable Energy Devices With countries such as Iceland, Costa Rica, New Zealand and Norway adopting green energy practices, renewable energy now accounts for a third of global energy. As this trend continues, more and more countries are looking to offshore energy sources to produce this renewable energy. In an opinion published December 17 in the journal Trends in Ecology and Evolution , the researchers identify situations in which green technology, such as wind turbines, wave energy converters and other marine renewable energy devices (DERMs) have had negative consequences for marine life. While the researchers do not want to slow down active responses to climate change, they encourage those making the decision to deploy Marine Renewable Energy Devices in marine habitats to consider the impact of this technology, such as head trauma and hearing loss, on marine animals before starting construction.
When people put a wind farm in their backyard, neighbors may complain that it's ugly and want it moved," says first author Andrew Wright, an ocean and ecosystem scientist at the Natural Sciences and Engineering Research Council. from Canada. "So, they think, why not put it off the coast where we can't see it and then there are no problems? The assumption is that it is just a Cell Phone Number List cosmetic problem. But there is much more. Green technology used on land, such as the wind farms mentioned by Wright, has had negative impacts on birds and bats, which collide with the huge rotating blades during migration or during their night flights. Likewise, when rotating objects, such as wave energy converters, are built underwater, marine animals such as dolphins and porpoises can be struck by the rotating blades, causing blunt force trauma. DERMs are not only physically dangerous. They are also noisy to build, which can disrupt the echolocation that some marine mammals use to hunt and navigate.
For example, the Taiwanese white dolphin, an endangered species that lives in a densely populated and highly industrialized region, faces large wind farm developments in its range. Unable to escape construction noise in their shrinking habitat, dolphins will likely suffer from hearing loss and chronic stress. Marine Renewable Energy Devices «Installing renewable energy sources in the ocean is a noisy operation. I would compare building marine renewable energy devices to living next to a construction site. Think about what it would be like to live next to all those jackhammers and power drills,” says Wright. "I don't think many people appreciate that when it's out at sea, it can be quiet for humans, but if you put your head under the water where the animals live, it's much, much louder." Even after construction is completed, the noise produced by DERMs can be harmful.
