In the past four years, 178 humpback whales have died1.40% of these deaths were due to human actions, such as ship collisions and getting tangled in fishing gear1.This statistic shows we need to urgently learn how whales and human activities, like wind turbines, can coexist. Although wind turbines are a hot topic, there’s no solid proof they harm whales, says Greenpeace1.
With more offshore wind farms being built, people worry about their effects on the sea and whales2.The Bureau of Ocean Energy Management (BOEM) has asked for a thorough review on this2.A team will first share their findings in October, then a complete report by March 1, 20242.
Looking deeper, we see ship hits are a big danger to whales, causing serious harm or death1. Yet, 60% of whale deaths are from unknown causes, which shows there’s a lot we don’t know1. Getting caught in fishing gear is also a huge problem for whales1. Still, we don’t have direct evidence that wind turbines are to blame for these sad events1.
Another interesting topic is whale strandings related to wind farm building1.In Europe, where offshore wind has been around for over 30 years, no proof links it to more whale deaths1.Moreover, before 2020 and major wind farm construction, whale strandings were already high1.This indicates that other issues may be more influential1.
When looking at wind farms and whale health, we must think about other human activities too1.Research in the USA is exploring all impacts, including those from wind farms1. Things like boat traffic, changing ocean temperatures, and food sources affect marine life’s health3.
The issue of wind turbines affecting whales is complex and needs broad understanding1. Despite concerns, there’s no proven link between wind turbines and harm to whales2. BOEM’s ongoing review will help shed light on how wind turbines and marine life can exist together1. By focusing on research and dealing with known threats, we can protect whales. At the same time, we can enjoy renewable energy’s benefits12.
Key Takeaways:
- Over the last four years, 178 humpback whales have died, with 40% of the deaths attributed to human-related activities like ship collisions and fishing gear entanglement1.
- There is no concrete evidence linking wind turbines to whale deaths or strandings, as reported by prominent environmental organizations like Greenpeace1.
- The Bureau of Ocean Energy Management (BOEM) has initiated an independent review by a committee to assess the impact of offshore wind development on marine ecosystems2.
- Whale deaths caused by ship collisions and fishing gear entanglement highlight the urgent need to address these known threats to whale populations1.
- Broader factors, such as vessel traffic density, ocean temperature changes, and shifts in food sources, also play a significant role in shaping the overall health and well-being of marine ecosystems3.
Understanding the Situation
Whale deaths are rising, and knowing why is important. Human actions like ship collisions and fishing nets cause many deaths. Research found about 40% of whales had injuries from ships or nets4. Yet, 60% of their deaths are a mystery, needing more research4.
In four years, 178 humpback whales died, worrying scientists4. From 2016 to now, 208 humpbacks were found dead from Maine to Florida4. This shows we must act fast. Warmer waters from pollution are also changing where humpback whales travel4.
Humans affect the ocean more than just whales. Since 1991, 72 unusual deaths have hit seals, manatees, whales, and sea otters4. Also, the amount of goods shipped has grown a lot, hitting 10.7 billion tons in 20214. These facts show how our actions hurt sea life.
There are only 356 North Atlantic right whales left, putting them in danger5. We need to fix things like fishing nets and ship paths5.
Understanding this problem means looking at both now and the future. Take offshore wind energy. It could hurt sea animals, including whales. We need to think about this carefully.
To save our seas and still get the energy we need, we have to look at the big picture.
Breakdown of Known Causes of Whale Deaths
Ship hits and fishing nets are big dangers to whales, often causing death or serious harm. These activities are behind many whale deaths. Still, we don’t always know what kills them. This leaves us wondering about other possible causes.
In the recent years, whale deaths have lessened along the Atlantic coast of the U.S. and Canada. From 2017 to 2020, 59 whales died each year, down from 78 in 20176. Even with this drop, we shouldn’t overlook other reasons behind these fatal events.
The UK, with over 2,600 offshore wind turbines, hasn’t linked these turbines to whale deaths on its shores6. This implies that offshore wind might not threaten whales here.
Recently, many whale deaths in New York and North Carolina were due to ships hitting them. In January alone, three whales died this way6. This shows ships are still a major risk to whales.
In the U.S., we have only two offshore wind turbines working, and some are being built or reviewed6. Offshore wind is just starting here. So, it’s unlikely to be causing whale deaths now.
Since 2017, there’s been a focus on why so many whales are dying6. NOAA even called the ongoing deaths since 2016 an Unusual Mortality Event. It’s clear we need to keep looking into the causes of whale deaths.
While ships and nets are still the top dangers for whales, we must also search for unknown causes. Understanding all the reasons whales die will help us protect them better. We need smart plans to keep whales safe and thriving.
The Debate Over Wind Turbines
Some people worry that wind turbines might be causing whales to die. However, groups like Greenpeace say there’s no real proof of this. They believe blaming wind turbines might take attention away from bigger problems like pollution and climate change.
The North Atlantic right whale population is about 360 now7. Whaling had reduced their numbers to under 100 by the 1920s7. Thankfully, conservation work helped their numbers grow to as high as 483 by 20107.
From 2011 to 2020, about 43% of North Atlantic right whales died7. Scientists fear they might mostly disappear in 30 years7. While some blame wind turbines, the truth shows other dangers. In the past seven years, 39 right whales were hurt or killed by getting tangled7. Ships also pose a big risk to these whales7.
For humpback whales, 208 have been stranded on the US east coast since 20168. Yet, there’s no evidence linking these strandings to offshore wind turbines8. Studies suggest human actions like getting caught in fishing nets or hit by ships are the main causes8.
Groups like NOAA and other organizations are trying to find out why whales are dying. They’ve discovered other reasons like parasites or not finding enough food can also lead to whale deaths8. And they found no connection between the deaths and offshore wind projects8.
Despite criticism, we need to look closely at offshore wind farms and whale safety. Offshore wind projects have permission to disturb marine mammals, including nearly three times the number of North Atlantic right whales alive today9. These permissions come from NOAA and don’t penalize the companies9.
Blaming wind turbines for whale deaths is too simple. Without solid evidence, it shifts focus from real issues like pollution and climate warming. We must keep studying and making wise choices to protect both renewable energy and sea life.
What Else Could Be Affecting Whale Populations?
Debates about wind turbines impacting whales are ongoing. But we must not overlook other dangers. For decades, whales have faced threats like shipping collisions and getting caught in fishing gears10. These incidents cause harm and death. Underwater noise pollution is another big challenge. It messes with their ways of communicating and navigating. This leads to more stress and changes in their behavior.
Research shows right whales hear sounds between 50 Hz and 2 kHz11. But the ocean’s noise is much louder, ranging from 200 Hz to 50 kHz. This noise can overlap with sounds from wind turbines. Wind farms make noise too, especially during construction. This noise could harm whales living nearby.
The real effect of offshore wind farms on whales is still a mystery10. But even before these farms were built, whales were dying. Many factors were to blame, including climate changes. These changes have shifted where whale food is found, leading to more whale deaths. The noise from setting up wind farms could also hurt whales’ hearing. Wind turbines might even affect the ocean’s food chain, impacting what right whales eat10. Yet, with so many turbines spread out, their impact might be small.
It’s easy to blame wind turbines for harming whales. But we must remember climate change is a big threat too10. Wind farms could help by reducing harmful gases in our air. This could help fight climate change, which is hurting whale populations. However, we must make wind farms carefully. We need to protect whales while we fight climate change12.

Investigating the Real Culprits
Researchers in the United States are hard at work studying whale deaths. They want to know what really causes these tragedies. By looking at how humans affect whales, they hope to find important clues. These clues could tell us why whales are dying13.
Noise pollution’s impact on whales is a major study area. How do offshore wind projects and other noises affect them? Scientists are figuring this out to help whales better survive13.
Scientists are also looking at how different threats add up for whales. They study how things like boat traffic, lost fishing gear, and pollution hurt these magnificent creatures. Understanding all these threats together is key to helping them14.
There’s a focus on the sounds from wind project studies versus those from oil surveys or military sonar. Wind project sounds are less bothersome to marine life. They have smaller areas of impact and are not as loud13.
The Bureau of Ocean Energy Management (BOEM) checks how wind turbines might affect marine mammals. They make sure offshore wind projects are safe for sea life. Their goal is to protect marine animals while supporting renewable energy13.
To protect whales, there are rules like speed limits for boats and special observers to look out for sea creatures. They also use bubble curtains to keep noises from bothering whales. These steps help reduce the risks to whales from human activities14.
Studying the effects of human actions on whales is crucial. This research sheds light on why whales die. With this knowledge, we can come up with better ways to protect them. It’s all about guaranteeing a future where whales thrive.
Wind Turbines: A Scapegoat?
Wind turbines have been criticized for increasing whale strandings. But, high rates of whale deaths happened before wind farms were built15. In the United States, along the Atlantic coast, whales were dying before large-scale wind farm construction. This indicates other causes might be more significant in the deaths of whales.
Since December, the East Coast has seen many whale strandings. A total of 25 humpback whales and 2 North Atlantic right whales have been found ashore16. New Jersey has seen at least 7 of these whale deaths. It’s key to remember these events occurred before offshore wind farms were common.
Some think offshore wind turbines harm whales or mess with their migration. Yet, there’s no strong proof for this16. Experts from NOAA Fisheries and the University of Southern Denmark deny any link between wind farms and whale deaths1617. So do those from the Bureau of Ocean Energy Management.
Other factors might be causing whale deaths. For example, climate change has warmed waters, changing where whales find food. This could make ship collisions more likely16. Shipping and mass fishing could also be killing more whales. Greenpeace’s John Hocevar says there’s no proof wind turbines are at fault15.
Some people wrongly blame wind turbines for whale deaths. Companies linked to fossil fuels might be spreading these false ideas. Organizations like the Caesar Rodney Institute and Texas Public Policy Foundation are part of this issue16. Fox News has even aired false claims about wind energy.
However, many leaders see the good in offshore wind farms. New Jersey’s Governor Phil Murphy backs wind energy for jobs, power, and climate action. New Jersey voters support this too, shown in the 2023 elections17.
The Biden Administration is all-in on renewable energy, including offshore wind. In just a few years, they’ve created 270,000 jobs and approved enough wind energy to power 4 million homes17.

Global Perspective on Wind Farms and Whales
There’s been worry about wind farms affecting whales. Yet, looking at this issue from a global view helps us understand it better. Europe has had wind farms for over 30 years. Here, there’s no proof that wind farms have caused more whale deaths. This shows the complexity of how wind farms might impact whales.
Europe leads in wind farm development, with many offshore projects in the UK, Denmark, and Germany. These projects not only produce clean energy but also cut down on harmful gases. They create jobs, support energy freedom, and help diversify our energy sources18.
Europe has done studies to see how wind farms could affect sea life, including whales. Developers use advanced tools like radar and thermal cameras to pick sites carefully. This reduces harm to wildlife18.
If whales or other sensitive animals are near, wind farm construction can stop. This shows how developers try to protect sea life18. After building, they keep an eye on the area for a year. They want to see how wildlife, like whales, are doing18.
Some people think wind farms hurt whales, especially in New Jersey. But, data from Europe shows wind farms aren’t a big danger to whales18. fe>.
Republican politicians have started debates and investigations into how offshore wind farms might affect sea life and fishing. They’ve even asked to pause some projects18. But it’s important to think about the bigger picture. Wind energy helps fight climate change, which can also affect whales. It can change where their food is and increase the dangers of ship strikes and getting caught in fishing gear19.
The concern about wind farms and whales continues. But, looking globally, we see no direct link between wind farms in Europe and more whale deaths. It’s key to keep researching and monitoring. This way, we can lower any risks and protect our oceans as we move toward cleaner energy.
Key Statistics
| Wind Farm Statistics | Whale Population Statistics |
|---|---|
| – Out of the two commercial offshore wind farms under construction in the United States, one is the South Fork Wind, located 35 miles east of Montauk Point, New York, with 12 turbines. The other is the Vineyard Wind, a 62-turbine farm situated 15 miles off Massachusetts19. | – There are fewer than 360 North Atlantic right whales remaining in the world1920. |
| – The Biden administration aims to power 10 million homes with offshore wind by 203019. | – In the 18th century, there were 9,000-21,000 North Atlantic right whales, reduced to fewer than 100 individuals by the 1920s, and rebounded to 483 individuals by 201020. |
| – NOAA reports 83 whale deaths off the U.S. East Coast since December 1, 202219. About half of the deceased were humpback whales between Massachusetts and North Carolina, and two were critically endangered right whales in North Carolina and Virginia19. | – Between 2011 and 2020, 43% of North Atlantic right whales died20. |
| – Humpback whales have been experiencing an “unusual mortality event” since 201619. | – Scientists estimate that the North Atlantic right whale species could become functionally extinct within the next 30 years20. |
Conclusion
Whale deaths are a big problem that needs us to look at many things to solve it. The debate often mentions wind turbines, but it’s clear many things hurt whale numbers. We need to figure out all the reasons and find ways to help whales.
According to data21, ships hitting whales are a huge problem, especially in New England for North Atlantic right whales. A study by Mark Baumgartner shows that fishing gear also kills many whales. From 2016 to 2023, over 180 humpback whales and 36 North Atlantic right whales died along the U.S. East Coast. This shows how serious the issue is.
The National Oceanic and Atmospheric Administration (NOAA) has been tracking “unusual mortality events” since 1991. These events show a worrying trend that we need to address quickly.
Even though people criticize wind turbines, they actually make less noise than the ocean or ships. Offshore turbines even help marine life by providing new homes for fish and other sea creatures.
To reduce whale deaths, we should change ship paths away from where whales travel. We could also use whale-safe fishing gear, like traps without ropes. Funding for this kind of gear could really help save whales.
Ship traffic has gone up by 34% in five years, data22 shows, making ship strikes more likely. This puts our ocean life at risk. Between 2016 and early 2023, over 62 humpback whales were hit by ships. During 2017 to 2023, ship strikes also affected over 15 North Atlantic right whales.
The Woods Hole Oceanographic Institution (WHOI) is working hard to understand how offshore wind power affects whales. They’ve gotten research money from Ørsted and work with many groups to plan wind energy projects carefully.
Solving whale deaths needs lots of research, watching the situation closely, and a plan that looks at all the ways whales are affected. If we use science, work together, and make careful policies, we can make a future where whales and green energy both do well.
Impact on Marine Ecosystems
Offshore wind energy projects impact marine ecosystems in both good and bad ways. It’s key to lessen these impacts to protect these sensitive environments.
The U.S. Department of Energy reports 59 offshore wind projects in development23. This growth points out the need for careful research and planning to reduce harm to marine ecosystems.
Some worry about the effect on marine wildlife. However, research shows offshore wind farms don’t kill whales24. The Marine Mammal Commission found no proof that wind farm development harms humpback whales24. This means offshore wind energy likely doesn’t threaten whale populations.
Compared to oil and gas activities, offshore wind farms have less severe effects on marine life24. Noise from installing wind farms can bother marine animals like dolphins, making them leave the area24. But this is less harmful than the damage from fossil fuels, which causes climate change and endangers marine ecosystems24.
Developers, like Ørsted, take steps to protect marine life. They limit ship speeds and stop work if marine mammals or turtles are near, lowering the risk of harm25. Before projects begin, thorough studies are done to find risks to birds and plan ways to help them, like restoring habitats25.
To lessen impact during construction, they use techniques to keep noise down. This includes things like bubble curtains and sound dampeners25. The offshore wind sector follows these rules to protect marine life. They use lower impact survey technologies to avoid disturbing marine mammals25.
It’s important to see that protecting marine ecosystems and offshore wind development can work together. Working together is key for the safety of marine life and the growth of clean energy. Using responsible methods and watching their impact, we can balance our energy needs and protect ocean life.
The Role of Renewable Energy
Renewable energy, like wind power, is key to fighting climate change and cutting down on fossil fuel use. The world urgently needs to focus on renewable energy to tackle the climate crisis. Switching to clean energy helps lower harmful emissions and keeps ocean species safe26.
Building things like offshore wind farms helps produce clean energy and protects sea life. Agencies like the Bureau of Ocean Energy Management (BOEM) and groups like the National Oceanic and Atmospheric Administration (NOAA) work together. They fund research on how offshore wind projects affect species like the North Atlantic right whale26. Their goal is to achieve renewable energy targets while ensuring marine animals are okay.
A main effort is to balance renewable energy growth with protecting animals. There’s a goal to install 30 gigawatts of offshore wind by 2030 that considers ocean life26. Research focuses on how offshore wind projects impact North Atlantic right whales and on tracking wildlife in digital images26. These studies help make sure expanding renewable energy doesn’t harm whales or their homes.
As offshore wind farms grow, we need to protect marine animals from harm. We must be cautious with construction near these farms to avoid disturbing marine life27. Also, the noise from wind turbines should be checked to ensure it doesn’t bother marine mammals27. By working together and focusing on research and nature, the renewable energy industry can boost clean power and help save wildlife.
