The truth about wind turbines and how they are one of the most cost-effective, fastest growing and arguably underused sources of energy currently available to us. But when a wind turbine is not in operation -- meaning, getting them built and working out what to do to recycle them once they're taken down -- they do have an environmental impact. How bad are they and is there anything we can do to mitigate it?

    I live in an area where a "wind farm" sprang up. Initially, it wasn't bad, other than the eyesore it created. It ruined the view of the countryside, day and night. Just very recently, a Second Phase was started, (which we were not told of, and by the time it was made public, it was finalized where the placement of the new turbines were going. Effectively, we were locked out of the process) and is nearly complete. With that Second Phase, 2 wind turbines were placed very, very close to my home (one being about 3/10's of a mile away, the other about 1/2 mile away). Literally just 4 days ago, they got them powered up, running. When they are in operation, it sounds like a jet flying high overhead in the sky, but in the same place without moving. It produces a constant sound from the blade tips passing through the air. It is very, very annoying. I can see why people complain about them.

    As someone whose home has just been surrounded by a wind farm, they suck way more than those who don't live by them realize. I also went back to college for environmental sciences because I very much care about the environment, so I'm not just being crabby here. I've lived in this area nearly 60 years now. We have tons of migratory birds that pass through our numerous ponds and marshes. I guess time will tell if they manage getting past these monstrosities with whirling blades moving at around 200 mph. I know we usually have Bald Eagles, but I haven't seen a single one since the turbines went up this fall. I've loved the quiet of the night here all of these years. The masses of stars in the sky were beautiful. Now I close the drapes to stop seeing the hundreds of red flashing lights that surround my property from every direction. I hate the thought of having to keep my windows closed on beautiful spring evenings to get the sounds of the motors and the swoosh of the blades out of my head. The gravel roads are a mess of deep tire tracks and washboards. The massive power lines, poles, transformers by the dozens and of course a new power station. There will be quieter days at times when the winds are silent, but they don't tend to build these turbines in places where there are too many windless days. The turbines will also shut down in high winds which seems ironic. I can say with 100% certainty that the recorded number of birds these things kill won't come close to reality as nature's cleanup crews will leave little to no trace of the bodies by the time the sun comes up the next morning. What have I learned about this green movement? Most people (including all political parties) want to improve our impact on the environment. Unfortunately, we are being scammed in order for certain groups to reap huge financial gains and/or power. We know there are so many cost-effective ways that are proven to work to clean up our environment. We have huge improvements coming for greener and more efficient solar and wind energy as well as battery technologies. There are also other energy sources being explored. The problem is that certain groups have invested heavily in what we have available today and they want to force us to buy it before better options replace it. The powers that be don't want to implement any of the cost effective, proven methods and I truly believe it is because they don't enrich or empower the right people. Some of the things these billionaires like Mr Gates are doing are NOT good at all. They are using chemicals to block out the sun which ends up contaminating our water and soil, but our government isn't interested in stopping him. The assault on livestock production is ridiculous. Far more energy and chemicals are used in growing plants. There are some changes that would be beneficial to make in our raising of livestock, but eating meat is not the enemy of the environment. Livestock can destroy land or it can add great benefit to the land depending on how it is managed and the land itself.
  • Just wanted to tell you that I appreciate you giving BOTH the negatives and positives of this method of energy production. Fair and balanced on this overly politicized topic is rare to find.
  • @sussell4606
    I was a tourist in the States in 1983 and came across a disused wind turbine farm in the middle of California. My host told me it was too expensive to demolish so it hadn’t been demolished yet.
  • @wadesworld6250
    Wind turbines also have to be shut down when it gets too cold, too hot, and ironically, too windy.
  • I think the bottom line in any energy production source is that the old adage of "there's no free lunch" comes into play.
  • I used to deliver cabins and containers onto wind turbine farms and was told on more than one occasion they never pay for themselves, as each full turn off the blade they get six pence, at that price they take fifty years to pay for themselves, but the turbines only last a max thirty to forty years.
  • @jamesa3482
    We must always keep in mind that while the source of energy is renewable, the infrastructure is not. When renewable energy can completely power our grid all the time and also we can build renewable infrastructure without fossil fuels then we'll mostly be using nuclear power. That's the reality.
  • My nephew worked on wind turbines and described the massive amount of oil lubricates leaked from most towers.
  • @RedHaloManiac95
    Here we are in Texas where 35% of the grid is wind and it’s only supplying 7% of the energy needed leading to blackouts. Solar is providing 3%. It’s not reliable at all and leads to consumers having to make sacrifices

    Thousands of bald eagles, golden eagles, herons, hawks and other endangered species killed by these contraptions are unavailable for comment.
  • @MrArtist7777
    Having worked in the commercial wind farm industry for many years and powering my own house with a small wind turbine (2.4kW), I can speak the truth that bird kills by wind turbines is far, far lower than estimates and opinions say they are. A 1 year study conducted in Kansas, at a large wind farm of 200 2mW wind turbines, found only: 2 dead birds, over the year, however, the fossil fuel industry, buildings, cars/trucks, house cats, account for hundreds of millions of bird kills every year and nobody cares. I fully support much larger wind turbines and wish they'd paint them tan or green, to match the landscape but think wind will top out at around 25% of entire energy production as solar can be put on virtually every roof, parking lot and structure, and will produce the majority of our energy in the future.
  • Obligatory nuclear energy comment. Very little land use, reuse of nuclear materials, Onagawa, there's a reason France is closer in hitting their emission reduction targets than Germany, etc.
  • @KrisOfTheSky
    It's important to ask the question "is it worse than the current option?"
  • @areafifty
    Fun fact: Energy companies are exempt from liability for killing endangered birds
  • @ajhubbell3754
    I work for an electric company. No one that I work with has a problem with “renewable” energy as long as it makes sense. So far, none really do. There are a lot of pros and cons pointed out here but there are many more cons that he didn’t bring up. The energy and materials needed to mine the raw materials used in these turbines is massive. The worlds consumption of copper and steel mean that new copper and steel must constantly be mined and processed. Yes these materials are recycled after the turbine comes down but to build a new one means that nearly all the materials have to be new. There is just more need for materials than past production and recycling can provide. We, in the industry, don’t resist “green” energy, in fact, my company is a leader in replacing our older production plants with more renewables, but it needs to make better sense than it currently does. Solar and wind produce more negative effects on the planet than they eliminate. Nuclear is a good source but we haven’t updated our handling and recycling rules for contaminated materials meaning that we end up burying it all (an environmental sin that will one day haunt us all). Hydroelectric is great but many people complain about it. Nothing will satisfy everybody. We are all waiting for that breakthrough in technology that solves the energy conundrum. I ask two things of people: 1 be patient as we try to fulfill the needs of society 2 get to work on that next great idea.
  • @stevemiller6766
    As one of the owners of a 106 turbine wind farm I worked on they have a 20 year payback. The main reason they built them was for the tax breaks. The ones i worked on were 1.5 MW and cost 1.5 million bucks a piece. Keep in mind also that if the grid goes down they shut down. The sub Sonics from blades is not pleasant. The fiber glass blades are not reclaimed. And they are not simple to work on. Try working on them. I have and don’t like it.
  • 1. Hybrid power plants (using both wind and solar) 2. More offshore than onshore winf turbines 3. Coloring the wind blades so as to avoid bird strikes. 4. Finding ways to reduce the use of diesel or petrol in construction and installation of wind farms. Inr way can be using wind turbines or solar panels for constructing newer turbines and/or panels. 5. Pyrolysis is one way to reduce landfilling. The easiest manner is the use of wind turbines in cement production as well as road construction. Their are claims being made now that we have found ways to profitably extract resins from wind turbines in an electricity positive manner.
