Wind energy is known to lots of as a “green” option to climate change. However wind energy is actually simply another kind of commercial advancement, and we can’t ignore its costs and consequences to wildlife and their habitats. As Director of ABC’s Bird-Smart Wind Energy Campaign, I often encounter a number of common misconceptions about wind development. Continue reading for more information about the real impact of unattended wind energy advancement on birds and other wildlife.
Myth 1: Wind turbines are “green” energy with little or no effect on the environment.Any type of energy
production, consisting of renewable resource, has environmental effects. The construction of large-scale, commercial wind energy facilities takes up entire landscapes, which minimizes wildlife habitat. And the upkeep roadways and other assistance infrastructure essential likewise modify habitats and impact wildlife, frequently in really negative, subtle methods. If not appropriately sited, operated, and controlled, renewable resource can be very hazardous to wildlife and natural habitats.Myth 2: We shouldn’t be worried about wind energy since it does
n’t take almost the very same toll on birds as feral felines, building collisions, pesticides, and other threats.There are two things to keep in mind here. Initially, wind turbines’impacts are far from trivial.
And the effects of all human-caused death are cumulative, making contrasts irrelevant and misleading.Wind turbines and their associated facilities– mainly power lines and towers– are among the fastest-growing threats to birds in the United States and Canada. At the end of 2016, there were more than 52,000 commercial-scale wind turbines running in the United States, and tens of thousands more are presently prepared or under building. Research shows that hundreds of countless birds and bats pass away every year when they accidentally hit the fast-spinning turbine blades. That number grows with each turbine built.Myth 3: Power lines and towers are a separate issue.Power lines and towers are clearly part of the equation, due to the fact that they’re essential to bring power to the grid. As an outcome of massive, commercial wind and solar
advancement, hundreds of miles of new power lines and towers
are being developed to transfer energy throughout the United States, putting birds at risk of collisions and electrocutions. The generation of energy and its transport go hand in hand– and both present dangers to wildlife. Tens of countless birds are killed every year when they collide with towers with or are electrocuted by electrical lines.Myth 4: The wind industry is alleviating for bird and bat deaths.As far as birds are concerned, only two mitigation methods have actually been proven to be effective: building wind energy facilities away from large concentrations of birds, and slowing or stopping the movement of turbine blades(understood in the industry as”curtailment”
). Neither of these techniques is working.
Turbines are going up essentially everywhere, and curtailment is out of favor with wind companies since it cuts into their earnings margins.Some companies state they use radar to spot birds and bats then temporarily closed down a turbine’s blades. These technologies are costly and appear to be seldom utilized– and their efficacy in avoiding bird and bat deaths has not been thoroughly tested. Northern Long-eared Bat/U. S. Fish and Wildlife Service One way to make wind turbines safe for birds and bats, such as this Northern Long-eared Bat, is to construct them far from big concentrations of these animals. Photo by U.S. Fish and Wildlife Service Myth 5: The U.S. Fish & Wildlife Service( FWS )and state wildlife companies are regulating the wind industry to decrease its effect on wildlife.We have at least 3 federal laws designed to secure our native birds and bats from purposeful or unexpected harm: the Endangered Types Act, the Migratory Bird Treaty Act, and the Bald and Golden Eagle Security Act. Enforcement of these laws has been erratic at best, particularly with regard to the wind market. To & make matters worse, federal standards governing wind energy development are voluntary, not mandatory, and couple of designers at present
are obtaining the” take” allows needed to kill secured species.Meanwhile, state and local policy of the wind market differs extensively. Some states, such as Oklahoma, have virtually no guidelines at all. Others, like Hawai’i, have more-stringent policies. Wind energy has actually established so rapidly that it has gotten method out ahead of the regulatory framework.Myth 6: Wind companies perform clinically strenuous research studies before and after brand-new facilities are developed to evaluate the threats wind turbines pose to birds– and are transparent in exactly what they find.Federal standards presently allow wind companies to hire specialists to prepare reports assessing a proposed center’s risk for wildlife. It is essential to note that these are not independent, third-party researchers; they are people who are being paid by wind business to do this work. Unsurprisingly, I have yet to come across any pre-construction research study that advises moving a proposed project due to the fact that of elevated threats to wildlife.There is also the problem of covert information. The wind industry deals with info on bird and bat mortality as an exclusive trade secret.
Some wind energy developers have actually even sued to hide these data from the public. Hawai’i is presently the only state that needs the collection of death data by independent, third-party specialists, and makes the info available to the public on request.Myth 7: Offshore wind development is less destructive than onshore wind development.There’s no indication that turbines placed outdoors ocean or in the Fantastic Lakes are any more secure for birds than land-based turbines.
A whole suite of various organisms could be affected by overseas wind development and undersea cables, consisting of moving marine birds, waterfowl, cetaceans, fish, and other ocean-dwelling wildlife. And it’s going to be harder to gauge the impact: threat evaluations are frequently based on visual observations, which can be difficult, if not difficult, during rough weather condition, when birds may be at highest threat.
What’s more, birds that collide with the turbine blades will fall into open water and be lost.Myth 8: We can
construct wind turbines in and around the Terrific Lakes with little or no effect on wildlife.The best method to decrease the impacts of wind energy on birds and bats is to keep turbines far from large concentrations of these animals. Significant migratory routes, stopover environment, and key breeding or foraging areas need to all be off-limits for wind advancement. All of these are discovered in and around the Great Lakes, which is home to one of the world’s densest concentrations of migratory birds and bats.Here at ABC, we oppose wind turbine construction in the Terrific Lakes and within at least 5 miles of its coastlines. We base our position on recent sophisticated radar studies conducted by the FWS on all five of the Terrific Lakes. All of the studies clearly show huge numbers of birds and bats flying over the lakes or along their coastlines, lots of within the rotor-swept areas of wind turbines. The FWS presently suggests that no turbines be constructed within three miles of the Great Lakes shorelines, while the Nature Conservancy suggests 5 miles. Nevertheless, these are simply recommendations, and some wind designers are neglecting them.Myth 9: When it comes to combating environment modification, there are no practical options to industrial-scale wind energy.There are many other ways
we can address climate modification besides developing these big structures in ecologically delicate areas. We can maintain wetlands and forests to sequester carbon dioxide; we can be more energy-efficient; and we can decrease our usage of fossil fuels and rely less on domestic animals(a significant source of greenhouse gases )as a protein source, for beginners. Among the very best choices is dispersed solar in our already constructed environment– car park, buildings, and roads.Myth 10: Environment change is the leading danger to wildlife today; we can disregard all other hazards because they pale in comparison.Birds and other wildlife face many hazards, and they add up. One recent analysis of 8,000 species
on the International Union for Preservation of Nature Red List of Threatened Species discovered that environment modification is not the most immediate danger
to wildlife today; that difference went to the standard risks of over-exploitation (overfishing, searching, and so on)and habitat loss from agriculture. The authors concluded that”efforts to attend to climate modification do not eclipse more immediate priorities for the survival of the world’s flora and animals.”We support wind energy advancement that’s done in manner ins which do not threaten our irreplaceable and ecologically crucial wildlife. To make that take place, wind energy development need to be regulated more efficiently. We need to deal with environment change, to be sure– however the point is that we could be doing it so much better.Michael Hutchins, Director of American Bird Conservancy’s Bird-Smart Wind
