The ongoing debate on whether wind farms harm wildlife more than oil and gas production highlights the need to balance the local effects of energy projects with the global threat of climate change.
In recent years, the debate over the environmental impact of wind energy has become more intense, especially with U.S. President Donald Trump’s administration pushing for a shift away from renewable sources like wind power to more fossil-fuel-based energy. Trump’s administration rolled back former President Joe Biden’s ban on new offshore oil and gas drilling in a bid to boost domestic energy production. Trump’s stance also argued that wind farms posed significant threats to wildlife, such as birds and whales, a claim that has sparked controversy among scientists and environmental advocates.
Aspen Ellis, a seabird biologist at the University of California, Santa Cruz, spent years researching seabird populations in remote U.S. coastal islands. She witnessed firsthand how climate change severely affected these populations, from rising sea levels threatening breeding colonies to altered fish migration patterns starving seabird chicks. As she added her findings to decades of previous research, Ellis realized that focusing solely on seabirds was not enough—climate change was a much larger threat. As a result, she shifted her focus to finding ways to make offshore wind farms safer for birds while combating climate change.
Wind farms, especially those located offshore, are increasingly seen as a vital solution to combating the climate crisis. However, environmental concerns have been raised regarding their impact on local wildlife. In particular, the construction of wind farms can cause habitat disruption, while the turbines themselves may pose a danger to birds, who risk collision with the rotating blades. But experts like Ellis argue that the potential benefits of renewable energy far outweigh these concerns, especially when compared to the more severe environmental damage caused by fossil fuel extraction.
The clash between wind energy and fossil fuels is at the heart of the larger debate surrounding the balance between local environmental impact and the broader threat of climate change. The world faces a daunting challenge: how to transition to cleaner, renewable energy while minimizing harm to ecosystems and wildlife. And, crucially, how do the impacts of wind power compare to those of oil and gas drilling?
Beth Scott, a marine ecologist at the University of Aberdeen, argues that the climate change effects caused by fossil fuels are far more damaging to wildlife than any adverse effects from wind farms. Scott, whose research focuses on the marine ecosystems surrounding Scotland’s growing wind energy industry, points out that wind farms can be developed quickly and at scale, offering a rapid solution to the global energy crisis. She emphasizes that the severity of climate change is far more detrimental to wildlife than the risks associated with wind energy.
For instance, extreme weather events caused by global warming are already becoming more frequent and intense, as seen in Scotland, where storms have grown more severe over the years. Scott believes that wind energy offers a timely remedy, especially since it can be constructed much faster than nuclear or fossil fuel plants, which take decades to build.
While wind farms do have potential risks for wildlife, including birds colliding with turbines and changes in feeding patterns due to habitat displacement, researchers are increasingly finding ways to minimize these impacts. For example, studies in Scotland have found that some animals, such as seals, have adapted to the presence of wind farms, using them as new hunting grounds for fish. Seabirds, on the other hand, may alter their routes to avoid turbines, but research is ongoing to determine the full extent of this behavior and its consequences.
In contrast, the risks of oil and gas drilling on wildlife are far more dire. Decades of research have shown that fossil fuel extraction causes significant harm to marine and terrestrial life, including habitat destruction, oil spills, and chronic pollution. One of the most devastating examples of oil’s long-lasting impact on wildlife is the Deepwater Horizon spill in 2010. Researchers have found that dolphins and whales in the affected Gulf of Mexico region suffered health problems such as chronic lung disease and damaged hearts. Additionally, the noise pollution created by oil exploration, particularly from seismic surveys, has disrupted the echolocation and communication abilities of marine mammals, leaving them disoriented and unable to locate food.
Oil and gas extraction’s noise pollution is particularly harmful because it is constant and pervasive, unlike the temporary noise caused during the construction of wind farms. Seismic surveys, for example, involve airguns that release loud blasts every 10 seconds, which can travel across vast stretches of ocean and disturb marine animals, including sperm whales, whose very survival relies on sound. In comparison, the noise created during wind farm construction is more short-term, and many countries are now requiring developers to implement measures, such as bubble curtains, to protect marine life from excessive noise.
Oil and gas extraction also generates constant pollution, including hazardous oil spills, which continue to affect marine life. While advances have been made in oil spill prevention and recovery, these efforts cannot fully offset the broader environmental toll of fossil fuel extraction. Onshore, both wind energy and fossil fuel production contribute to habitat fragmentation, but research by Colorado State University’s Liba Pejchar found that wind energy causes less long-term habitat disruption than oil and gas drilling. Unlike oil and gas fields, which require constant drilling and extraction, wind farms continue to generate energy for decades without the need for further land development.
Meanwhile, fossil fuel extraction continues to exacerbate climate change. Methane, a potent greenhouse gas, is released during oil extraction, and its contribution to global warming only worsens the extreme weather patterns caused by climate change. As these patterns intensify, ecosystems and wildlife suffer even more.
Despite these challenges, both the wind energy and fossil fuel industries are actively working to reduce their environmental footprints. In 2022, a group of scientists, including Ellis, developed strategies to mitigate the impact of wind farms on seabirds, including better site selection and the creation of alternative nesting habitats. These strategies have shown promise, and similar approaches could be applied to other species, such as bats and whales.
Ultimately, however, the larger issue remains the global threat posed by climate change. While efforts to reduce the impacts of energy infrastructure are critical, they do little to address the broader need for a transition away from fossil fuels. If left unchecked, climate change will continue to wreak havoc on ecosystems and wildlife around the world. And, as the world moves forward in its pursuit of renewable energy, finding ways to build infrastructure that minimizes harm to wildlife will remain a key challenge.
The future of energy production is intertwined with the fate of the planet’s ecosystems. As nations like the U.S. and others invest in renewable energy solutions, the question of how to balance their environmental impact with the urgent need to combat climate change will be felt across every habitat on Earth.
