Did you know wind turbines don’t create more wind? They use the wind that’s already there to make electricity. People often think they make more wind, but that’s not how they work.
Wind power is a key renewable energy source. Germany is a leader in this, putting 123.45 TWh of wind energy into its grid in 2022. This shows how important wind turbines are for energy1.
Some believe wind turbines have bad effects. But, it’s crucial to know the real facts. This article will clear up myths about wind turbines. We’ll look at their real impact on nature and communities.
Myth #1: “Wind turbines only stand still.”
Many think wind turbines don’t move. They’re actually made to spin and catch wind energy. The wind moves their blades, turning wind force into electricity. So, it’s not true that turbines just stand still.
Key Takeaways:
- Wind turbines use existing wind to generate electricity1.
- In 2022, Germany will benefit from 123.45 TWh of wind power1.
- Wind turbines are designed to rotate and harness wind energy.
Myth #1: “Wind turbines only stand still.”
Despite what some think, wind turbines move. They capture the wind’s power and turn it into electricity. Because of this, wind energy is growing fast worldwide. Wind turbines are key for making energy that is clean and lasts.
Wind turbines are always moving to catch the wind’s force and use it. This action creates electricity for houses, businesses, and whole places. The blades spin to take as much energy as possible from the wind.
Germany, for instance, has advanced in wind energy, adding about 123.45 TWh of wind electricity to their grid in 2022. This facts2 shows how crucial wind turbines are for supplying energy. It also helps cut down on using fossil fuels.
Sometimes, wind turbines aren’t moving because they need upkeep, to protect birds, or to manage the energy grid. These stops are needed for their safe and good performance. Safety and efficiency are top priorities in these breaks.
Also, wind turbines turn off in very strong winds to stay safe. They stop automatically if winds hit speeds like 55 mph3. This action prevents harm to the turbines and the area around them from too much wind.
The idea that wind turbines don’t move is wrong. They play an active role in making clean, renewable energy. This helps fight against climate change. Wind turbines are essential for a sustainable future. They lower CO2 emissions, aiding in making our planet cleaner and greener4.
Myth #2: “Wind turbines kill birds.”
There have been worries about birds dying because of wind turbines. But, evidence shows wind turbines are not a big threat to birds. In fact, wind turbines cause fewer bird deaths than buildings or other ways of making energy5. For each gigawatt hour of electricity from wind, only 0.27 birds die. This is much less than the 5.18 bird deaths caused by fossil fuel plants5.
Also, newer wind farms with taller turbines cause even fewer bird deaths. Offshore wind farms barely affect migratory birds because of how they fly5. In most wind parks, bird collisions are not a big issue5. Wind farm planners work hard to keep birds safe, like painting turbines black to stop them from hitting the turbines5.
It’s key to remember wind turbines don’t harm bird populations much compared to other human activities. For instance, in Germany, more than 18 million birds die every year from hitting glass5.
Wind turbines are good for the environment too. They pay back the energy used to make them in 3-9 months5. They’re quiet, making as much noise as the wind or a fridge from 230-300 meters away5. Also, no study has found that their infrasound is harmful to people5.
Even though some birds have hit wind turbines, the research says they’re not a big danger to birds. We need to build and run them responsibly. This will help us protect birds and benefit from wind energy.
Myth #3: “The infrasound generated by wind turbines makes people sick.”
Some people think that the low sounds from wind turbines can make us sick. These sounds are called infrasound and are too low for us to hear. Even though wind turbines make these sounds, they’re not strong enough to hurt us6.
Actually, infrasound comes from many things like wind, thunder, and cars. These everyday sounds also create infrasound, but we usually can’t hear it. So, the idea that wind turbines alone make us sick with infrasound doesn’t make sense6.
Studies have looked into how wind turbine sounds affect our health. They all agree that the infrasound from these turbines is too low to harm us. The sound levels are much lower than what could cause problems6.
Infrasound is part of our daily lives and it doesn’t make us ill. The false beliefs about wind turbines and sickness come from not knowing the facts. Misinformation spreads easily on the internet and by word of mouth6.
It’s natural to worry about wind turbines and health. But, we should trust what science tells us. The data proves that the infrasound from wind turbines isn’t harmful. There’s no proof that these turbines cause health issues6.
Myth #4: “Wind turbines are not recyclable.”
Many people think wind turbines cannot be recycled. But they’re wrong. Wind turbines can actually be recycled up to 90%. This makes them good for the environment.
Wind turbines last about 20 to 30 years. After that, they can still work without financial aid.
When it’s time to take them down, we can recycle lots of their parts. This includes the metal, electrical systems, and more.
This way, we don’t waste precious resources. We also reduce harm to the environment.
Recycling wind turbines is key for a circular economy. This approach helps us reuse materials. It also cuts down the need for new resources and lowers carbon emissions.
Remember, wind turbines are mostly recyclable. They help us move towards a green future.
Myth #5: “Wind energy is not energy efficient.”

Many people think wind energy isn’t efficient. But actually, wind turbines are among the best ways to make power. They quickly make more energy than it takes to build and run them.
Wind turbines produce clean energy for over 20 years. This greatly reduces their carbon footprint9.
Wind turbines are more efficient than old power plants. While coal or gas plants lose a lot of energy, wind turbines don’t. They turn wind into electricity without wasting much.
The world is installing more wind power than ever. From 2012 to 2017, wind capacity grew by 91%. It’s expected to grow even more by 2035 and 2050.
This growth shows that people believe in wind power. They see it as a source of energy for the future9.
Wind systems aim to be as efficient as possible. They get inspected every 6 to 12 months. This helps them work well, even when there’s not much wind.
If anything breaks, it’s fixed quickly. This keeps the turbines running smoothly10.
Turbines can turn off automatically in bad weather. This is to keep them safe. For example, they stop if winds are too strong or if ice might build up.
Shutting down during severe weather prevents damage. It keeps everything running safely10.
In summary, wind energy is a top choice for clean power. Its growth and improvements show it’s key for a cleaner future.
Myth #6: “Wind turbines destroy the landscape.”
Some people think wind turbines spoil the view. This idea changes over time, just like opinions on old windmills did. Now, they are often seen as normal in the scenery. Wind turbines use very little land, about 2% in Germany, to help a lot with wind power. Rules make sure they’re not built in protected or important forest areas.
Wind turbines work at 16% to 42% efficiency, but they could reach 59%11. How much power they make depends on the air, blade size, and the wind speed11. If the wind goes twice as fast, turbines make eight times more power. Making the wind speed four times faster increases power 64 times11.
In the United States, wind turbines make up 8% of the electricity12. Since 2000, wind power use has jumped 35 times12. Experts think wind turbine power will grow four times by 205012.
Statistic | Value |
---|---|
Percentage of land used by wind turbines in Germany | 2% |
Contribution of wind turbines to US electricity generation | 8% |
Wind power expansion in the US since 2000 | 35-fold |
Wind turbines change airflow and might alter local weather over time11. Their placement is key to reaching up to 59% efficiency11.
Though wind turbines affect land and weather, their role in clean energy and sustainability is vital.
Myth #1: “Wind Turbines Are a Danger to Wildlife”
Some worry about wind turbines hurting wildlife. Studies show, however, their effect is very small. This is when we compare them to other human-made structures like buildings.
It’s true that wind turbines can be a threat to birds. But, new technology and smart placement of turbines are making things better. These steps help lower how much wind farms affect animals.
Painting turbines black helps birds see them and not fly into them13. Wind turbines impact birds less than things like lost habitats. In the U.S., turbines cause less than 1% of bird deaths caused by people13.
Before building wind farms, there are detailed checks on how they’ll affect nature. These reviews look at how animals live in the area and how they move. This helps pick the best places and designs for turbines that won’t harm wildlife much.
Wind farms can also do good by protecting natural areas. They lessen the need for energy from fossil fuels. Burning fossil fuels is making climate change worse. This change threatens many animals across the globe.
Myth #2: “Wind Energy Has a Negative Effect on Agriculture”
Wind energy and agriculture can get along well. Wind turbines are designed to use land efficiently. This allows both renewable energy generation and farming to happen on the same land. Landowners can still grow crops and have animals graze, even with wind turbines around.
Wind energy leases mean extra money for landowners. They don’t really change how farming is done. Agreements make sure there’s enough room for both turbines and farming. This way, landowners benefit from both wind energy and their usual agriculture activities.
Wind projects are also good for sustainable land use. Using wood instead of steel for turbines cuts carbon emissions by a lot, up to 90%14. It’s better for the planet and keeps in line with renewable energy goals.
Studies in the US and UK show wind farms don’t hurt wildlife, like whales, dolphins, or birds14. A study in the North Sea found seabirds stay away from turbine blades. There were no bird accidents in two years of watching14. This proves wind energy and wildlife can coexist.
While wind power comes and goes, new solutions are being found. These innovations will help make clean energy more reliable. As these technologies get better, wind energy will become a more dependable source of power for farming and more14.

Steel manufacturers are exploring alternative methods for steel production, such as green hydrogen or renewable energy sources, aiming for lower-carbon steel production methods. | 14 |
Using timber instead of steel in wind turbine construction could generate 90% less carbon dioxide emissions, with modular segments from the tower being reusable. | 14 |
Reports in the US and UK show no evidence of harm to wildlife, such as whales, dolphins, and bird apparatus, caused by offshore wind farms. | 14 |
A study in 2023 in the North Sea revealed that seabirds avoided wind turbine rotor blades, with no recorded collisions during two years of monitoring. | 14 |
Electricity generation from sources like wind or solar energy can be intermittent, prompting the development of solutions for consistent clean energy supply. | 14 |
Myth #3: “Wind Energy is More Expensive”
Many think wind energy is pricier than older energy types. But, wind energy now competes in price, thanks to new turbine tech. It’s becoming as affordable as coal.
The National Renewable Energy Laboratory (NREL) studied how wind farms affect birds. They found less than 1 in 30,000 birds are harmed15. This shows wind turbines have a tiny effect on bird deaths.
In Norway, painting wind turbines black cut bird deaths by 70%15. This proves we can reduce risks to birds with simple changes.
Wind farms need up to 80 acres, but only a small part is for the turbines15. This means they don’t disrupt much land, allowing efficient wind power production.
Improvements in turbine technology have made wind power cheaper than coal in many places15. Bigger turbines now make more power at lower costs. So, wind power is both feasible and budget-friendly.
The U.S. Energy Information Administration says wind turbines don’t pollute the air or water15. This makes wind energy a clean, green choice over traditional fuels.
A 2018 study showed no link between wind turbines and health issues like sleep disorders15. This clears up worries about wind power harming our health.
To sum up, wind energy being more expensive is a myth. It’s shown to be a cost-effective, eco-friendly option for power. Technological advances and minimal environmental or wildlife impact make wind a top choice against fossils.
Conclusion
There are a lot of myths about wind turbines and windmills. But the truth is, they are extremely important for generating clean, renewable energy. They are also cost-effective, competing well with other energy types. In 2013, the price was about 2.5 cents for every kilowatt-hour16. This power source is great for the economy too. It creates jobs and increases people’s income16.
What’s more, wind power is good for the planet. It cuts down on water use and carbon dioxide emissions16.
Wind turbines have become a key part of America’s energy scene. By 2021, they were generating more than 9% of all electricity in the U.S17.. This made wind power the second-biggest source of new electricity generation17. States like Iowa, South Dakota, Kansas, Oklahoma, and North Dakota get a lot of their electricity from wind17. Wind projects can be found in every state and offshore, showing just how popular and useful wind energy is17.
Yes, there are worries about birds being harmed by turbines. Yet, there’s ongoing work to reduce these risks and protect our feathered friends18. Research has also found that living near wind turbines can be good for your health, despite some concerns about noise and shadow flicker18. The noise level is usually lower than the threshold that might cause health issues, which is reassuring to those living close by18.
Looking into the future, wind energy is very promising for the U.S. It will help the country reach its aim of zero net emissions and grow the renewable energy industry. Thanks to continually improving technology and research, we’ll overcome challenges. This means wind turbines will become an even more effective and eco-friendly power source.
