Will we run out of wind?
We will never run out of wind energy. It is a renewable energy source. It is also free, since no one can own the sun or the air. Some places have more wind than others.
Are wind farms environmentally friendly?
Wind power is the most efficient technology to produce energy in a safe and environmentally sustainable manner: it is zero emissions, local, inexhaustible, competitive and it creates wealth and jobs.
Is wind energy free?
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments offer tax incentives to spur wind-energy development.
What are 2 disadvantages of wind energy?
The two major disadvantages of wind power include initial cost and technology immaturity. Firstly, constructing turbines and wind facilities is extremely expensive. The second disadvantage is technology immaturity.
What are the disadvantages of wind farms?
Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape. Wind plants can impact local wildlife. Birds have been killed by flying into spinning turbine blades.
How often do windmills fail?
One study found that 25% of wind turbine faults caused 95% of the downtime. Reliability of wind turbines has improved with time and has achieved an availability of 98%, but wind turbines fail at least once per year, on average, with larger wind turbines failing relatively more frequently.

How much pollution would a 100 MW wind project cause?
For instance, just the rare earths of a typical 100 MW wind project would generate approximately: 20,000 square meters of destroyed vegetation, 2 million pounds of CO2, 6 million cubic meters of toxic air pollution, 29 million gallons of poisoned water, 600 million pounds of highly contaminated tailing sands, and.
What is the penalty for wind proponents?
2 – There is no penalty for making bogus assertions or dishonest claims about their product’s “benefits,” so each successive contention is more grandiose than the last.
What was the marketing opportunity that the wind energy business needed?
2 – Fast forward to several years ago. With politicians being convinced that Anthropogenic Global Warming (AGW) was an imminent catastrophic threat, lobbyists launched campaigns to favor anything that would purportedly reduce carbon dioxide. This was the marketing opportunity that the wind energy business needed. Wind energy was resurrected from the dust bin of power sources, as its promoters pushed the fact that wind turbines did not produce CO2 while generating electricity.
What is the difference between wind energy and conventional energy?
11 – A subtle (but significant) difference between wind energy and other conventional sources of electricity is in power quality. This term refers to such technical performance factors as voltage transients, voltage variations, waveform distortion (e.g. harmonics), frequency variations, and so forth. The reality is that wind energy introduces many more of these issues than does a conventional power facility. Additional costs are needed to deal with these wind-caused problems. These are rarely identified in pro-wind economic analyses.
What is the equivalent of a wind turbine?
In energy generation terms, the wind turbine equivalent is to attempt to replace the single truck with golf carts. How many golf carts would it take to equal the cost, speed, reliability and load capacity of a single eighteen-wheeler in making daily interstate deliveries? This is a trick question, as the answer is that there is no number that would work: not ten, not a hundred, not ten thousand, not a million. Exactly the same situation exists in the electricity sector: no number of turbines will ever equal the cost, reliability and output of one conventional electricity plant.
When was wind energy abandoned?
1 – Wind energy was abandoned for most commercial and industrial applications, well over a hundred years ago. Even in the late 1800s it was totally inconsistent with our burgeoning, more modern needs for power. When we throw the switch, we expect that the lights will go on – 100% of the time.
Is there any scientific proof of wind energy?
The frequently cited Bentek study ( How Less Became More) is a sample independent assessment of this aspect. More importantly, there has been zero scientific empirical proof provided by the wind industry to support their claims of consequential CO2 reduction.
What was the marketing opportunity that the wind energy business needed?

Is wind energy more reliable than nuclear energy?
First, abundant sources that are not reliable and that are not low-cost (i.e. wind energy), are a net detriment to our economy. Second, if they are really saying that abundance should be our primary focus, then they should be promoting nuclear power and geothermal energy. Both of these sources have something like a million times the available energy that wind does. Both of those are orders of magnitude more reliable than wind is. Both are lower cost when comparing the actual levelized cost of wind energy (e.g. Wind+ Gas).
Is wind energy low cost?
10 – Along the way, yet another claim began making the rounds: that wind energy is low cost. This is surprisingly bold, considering that if that were really true, RES/RPS mandates would not be necessary. For some reason, all calculations showing wind to be “low cost” conveniently ignore exorbitant subsidies, augmentation costs, power adjusting (see next item), additional transmission costs, and so on. Independent analyses of levelized costs (e.g. from the EIA) have concluded that (when ALL applicable wind-related costs are accurately calculated) wind energy is MUCH more expensive than any conventional source we have.
Does externality analysis take into account the environmental consequences of wind energy?
To gullible sheeple, this might make sense. But consider the following two points. First, externality analyses posited by wind zealots never take into account the true environmental consequences of wind energy (rare earth impacts [see below], human health effects, bird and bat deaths, the CO2 generated from a two million pound concrete base, etc.).
Is wind energy a capacity resource?
14 – Since this enormous Firm Capacity discrepancy is indisputable, wind energy apologists then decided to adopt the strategy that wind energy isn’t a “capacity resource” after all, but rather an “energy resource.” Surprisingly, this may be the first contention that is actually true! But what does this really mean?
What are the negatives of wind energy?
There are some very minor and easily managed negative aspects of wind energy. Noise - They make a small amount of noise. It’s about equivalent to a normal living room at the base. Setbacks of about 400 meters usually suffice to meet World Health Organization recommendations for night time noise so that sleep isn’t disrupted.
Why does wind change temperature?
Change surface temperature slightly under wind farms - Studies have shown a degree F increase at night and a degree F decrease during the day. This is due to mixing of layers of air. It’s thought to be beneficial to crops and vegetation in net, as it reduces the risk of frost damage to crops and increases surface level humidity slightly.
Why are wind turbines important?
Wind turbines are one of the two major wedges in the fight against global warming, climate change and air pollution. Along with solar energy, wind energy is going to be built in massive quantities globally. And that’s good because its negative externalities are so much lower than the current energy sources that they are close to non-existent.
Why do bats die?
Bat deaths - Bats suffer barotrauma when they fly into the low pressure behind the blades and die. This doesn’t happen in great numbers. Mostly its non-endangered tree bats which this happens to. It’s significant because cave bats in the USA are suffering from White Nose Syndrome, a fungal infection which has been wiping out cave populations, killing hundreds of thousands at a time. When a population is that at risk, even a death or two can be an issue. Luckily, it appears as if a cure for White Nose has been identified and remediation of that issue is being done. While it’s possible to reduce bat mortality at wind farms by raising the cut in speed of the turbine slightly, it has not been found to be required as non-endangered bat deaths are like non-endangered bird deaths, a cost of industrial society.
Is wind good for crops?
It’s thought to be beneficial to crops and vegetation in net, as it reduces the risk of frost damage to crops and increases surface level humidity slightly. Most of the complaints against wind farms are hyped by anti-wind advocates who fall into a few predictable categories.
What are the challenges of wind power?
Challenges of Wind Power. Wind power must still compete with conventional generation sources on a cost basis. Even though the cost of wind power has decreased dramatically in the past several decades, wind projects must be able to compete economically with the lowest-cost source of electricity, and some locations may not be windy enough ...
How does wind affect the environment?
Turbines might cause noise and aesthetic pollution. Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape. Wind plants can impact local wildlife.
How do wind turbines work?
Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth's surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid. Wind turbines can be built on existing farms or ranches.
Why is wind energy important?
Because the electricity from wind farms is sold at a fixed price over a long period of time (e.g. 20+ years) and its fuel is free, wind energy mitigates the price uncertainty that fuel costs add to traditional sources of energy. Wind creates jobs. The U.S. wind sector employs more than 100,000 workers. (link is external)
What is wind vision report?
The Wind Energy Technology Office's Wind Vision Report quantifies the costs and benefits of a robust wind energy future across all 50 states.
How do wind turbines affect wildlife?
Wind plants can impact local wildlife. Birds have been killed by flying into spinning turbine blades. Most of these problems have been resolved or greatly reduced through technology development or by properly siting wind plants.
Why can farmers and ranchers continue to work the land?
Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land. Wind power plant owners make rent payments to the farmer or rancher for the use of the land, providing landowners with additional income.
How many bald eagles can be killed by wind?
On January 17, 2017, the number of bald eagles that can be killed by wind farm permit holders will increase from the current legal number of 1,100 to 4,200 —almost a quadrupling. The Fish and Wildlife Service is issuing new 30-year permits that allow the additional eagles to be killed or injured without prosecution under the Bald and Golden Eagle Protection Act.
How much wind does Ercot have?
Ercot now has 20 gw of wind and I have seen it peak to 18 gw a few times. (typically 8 gw in the evening)
Is autonomous vehicle more feasible than wind turbine?
And this blog is a big proponent of the autonomous vehicles, which are far less feasible in stochastic settings than wind turbines. We’ve only to look at Uber’s failure, one that is increasingly looks like their AV detection system isn’t even half as good as the stock system available on many cars today, including the one they disabled on their autonomous car.
Is wind forecasting good?
As I noted a large part of stability is good weather forecasting, which if you notice has generally gotten better. Here is a link to a web site that provides a description of how wind is forecast for turbines. Note they do a day ahead forecast and then at least an hourly forecast to update over time. Statistics show about a 4% error rate on the forecasts. Partly this is due to better and better numerical weather models, whose primary output is wind forecasting.
Is wind energy expensive?
A hundred-plus years ago, wind energy was recognized as an antiquated, unreliable and expensive source of energy – and now, after hundreds of billions of wasted tax and consumer dollars, we find that (surprise!) it still is an antiquated, un reliable and expensive source of energy. This is what happens when science is relegated to a back-of-the-bus status.
Do wind turbines have to prove their claims?
No. 1 – Wind proponents are not asked to independently PROVE the merits of their claims before (or after) their product is forced on the public.
Is wind energy low cost?
No. 10– Along the way, yet another claim began making the rounds: that wind energy is low cost. This is surprisingly bold, considering that if that were really true, RES/RPS mandates would not be necessary. For some reason, all calculations showing wind to be “low cost” conveniently ignore exorbitant subsidies, augmentation costs, power adjusting (see next item), additional transmission costs, and so on. Independent analyses of actual costs (e.g. here) have concluded that (when ALL applicable wind-related costs are accurately calculated) wind energy is MUCHmore expensive than any conventional source we have.
What are the promises of wind turbines?
Prospective neighbors of wind turbines heard all the promises: “Quiet as a library.” “Like a baby’s breath.” “The same decibel level as a refrigerator.” The more brazen wind developers claimed, “You will not hear them.”
How much noise is needed for wind turbines?
Nighttime background noise levels in the areas where wind turbines have been constructed are about 20 dBA. Ten dBA above background is well known to result in complaints. It is the noise standard that has been used in Massachusetts for decades. By that measure, the correct standard for wind turbines in the very quiet areas where wind turbines are being built would be 30 dBA — lower than the PSB is proposing.
Do wind developers keep promises?
The wind developers have made big promises. Now they have promises to keep — so their neighbors don’t have miles to go before they sleep. And the Vermont Public Service Board should establish standards that reflect those promises.
Do wind turbines make noise?
The unique noise produced by wind turbines does not create a problem for the wind industry, though. “There are no problems,” is their attitude. “It’s all in their heads,” they state. “The ‘nocebo effect’ is at work,” they claim, alleging that people’s beliefs are making them sick. They heap ridicule on neighbors who are victimized once by the wind turbines themselves, a second time by the industry which refuses to accept responsibility, and a third time by regulators who have turned a deaf ear to the hundreds of complaints filed by Vermonters since mountaintop wind turbines began operating.
How does wind affect the environment?
Wind’s environmental impact has also been called into question in other ways. There have been complaints from some people who live or work near wind farms about the noise the turbines make. In other places, birds and bats have been discovered unwittingly flying into them, and this is thought to have contributed to a noticeable decline in the numbers of certain species. In the US alone, it’s estimated that as many as half a million birds are killed in wind turbine collisions each year, and with wind energy capacity due to increase significantly in the coming years, this figure could reach almost one and a half million a year 9.
How much electricity would wind farms generate?
According to the International Energy Agency, or IEA, if we built wind farms on all of the usable offshore sites worldwide sticking to certain conditions — that is, no further than 60km off the coast and in waters no deeper than 60m — they could generate more than the world’s entire current electricity demand on their own 6. But this would mean huge swathes of wind turbines popping up on practically every spare stretch on our coastlines, and would we want that? Probably not, but it does show what we could do with wind power if we really went all-out with the technology.
Why are wind turbines considered green?
It’s also perceived as one of the greenest because wind turbines don’t produce any greenhouse gases or pollutants while in operation. But that’s the rub: when they’re not in operation — meaning, getting them in the ground and working out what to do with them once they’re taken down — they do have an environmental impact.
What to do with wind turbines?
Another dilemma is what to do with the turbines once they come to the end of their lifetimes. How exactly do you dispose of these structures when they can be as big as a skyscraper, and there might be hundreds of them on a single farm? The good news is that around 85% of a wind turbine’s components can be recycled or reused 13, from the copper wiring and electronics to the gearing mechanisms, but the same can’t really be said for the blades, which are usually made from composite materials such as fiberglass or carbon fiber, depending on their age.
Why are turbines declining in Germany?
In Germany, installations have declined sharply due to lack of suitable land and a rise in people successfully campaigning against plans to build turbines in their area, and it’s dealt a blow to their carbon reduction plans 12. Another dilemma is what to do with the turbines once they come to the end of their lifetimes.
How long do wind farms last?
They’re simple to maintain and should last for decades; they’re cheap to run, and their footprint is actually relatively small despite their size 1. According to a survey of large-scale wind farms by the National Renewable Energy Laboratory in the United States, which has the highest wind power capacity in the world behind China 2, less than one acre per megawatt of power output capacity is disturbed permanently and less than 3.5 acres per megawatt are temporarily disturbed during construction 3. Costs are also coming down all the time with many governments now offering incentives to encourage more uptake 4.
How much energy does wind produce?
Although offshore wind only accounts for around 0.3% of total energy generation worldwide, it’s capable of making a much bigger contribution.
Why is wind power not the answer?
On October 8, the Intergovernmental Panel on Climate Change released a report warning that nations around the world must cut their greenhouse-gas emissions drastically to reduce the possibility of catastrophic climate change. The report emphasizes “fast deployment of renewables like solar and wind” ...
Why are rural residents objecting to wind turbines?
Rural residents are objecting to wind projects because they want to protect their property values and viewsheds. They don’t want to see the red-blinking lights atop those massive turbines, all night, every night, for the rest of their lives. Nor do they want to be subjected to the health-damaging noise —both audible and inaudible—that the turbines produce.
What states are against wind turbines?
The backlash against Big Wind is coast to coast. In New York, which has mandated 50 percent renewable-energy usage by 2030, the towns of Yates and Somerset are fighting against Lighthouse Wind, a 200-megawatt wind project proposed for the shores of Lake Ontario. In Oklahoma, the tiny town of Hinton continues its battle against NextEra Energy, the world’s biggest wind-energy producer, over the siting of wind projects nearby. In California, which just boosted its renewable-electricity mandate to 60 percent by 2030, wind turbines are so unpopular that the industry has effectively given up trying to site new projects there. Meantime, in deep-blue Vermont, both gubernatorial candidates—incumbent Republican Phil Scott and Democratic challenger Christine Hallquist—favor renewable energy in principle but oppose further wind-energy development in the state.
How tall are wind turbines?
Further: “While improved wind turbine design and siting have increased capacity factors (and greatly reduced costs), they have not altered power densities.” In other words, though Big Wind has increased the size and efficiency of turbines—the latest models stand more than 700 feet tall—it hasn’t been able to wring more energy out of the wind. Due to the wind-shadow effect, those taller turbines must be placed farther and farther apart, which means that the giant turbines cover more land. As turbines get taller and sprawl across the landscape, more people see them.
What is the Achilles heel of wind energy?
But the new study, published in Environmental Research Letters, shows yet again that wind energy’s Achilles heel is its paltry power density. “We found that the average power density—meaning the rate of energy generation divided by the encompassing area of the wind plant—was up to 100 times lower than estimates by some leading energy experts,” said lead author Lee Miller, a postdoctoral fellow who coauthored the report with Harvard physics professor David Keith. The problem is that most estimates of wind energy’s potential ignore “ wind shadow, ” an effect that occurs when turbines are placed too closely together: the upwind turbines rob wind speed from others placed downwind.
What states has Big Wind sued?
The wind-energy giant also sued local governments in Michigan, Indiana, and Missouri, all of which had passed measures restricting wind-energy development.
Is wind energy a federal or state mandate?
The reality is that wind energy’s expansion has been driven by federal subsidies and state-level mandates. Wind energy, cannot, and will not, meet a significant portion of our future energy needs because it requires too much land. Miller and Keith’s paper shows that the ongoing push for 100-percent renewables, and, in particular, ...
