Your Questions About Wind Turbine Generators How They Work

Daniel asks…

Where can gold be used in wind turbines?

The main parts of a wind turbine is the blades, the rotor, the generator, the tail and the tower. But where (and how) can “gold” be used in one of these parts (or others) when the properties of gold is put into consideration?
Thank you for your answer, but if you HAVE to use gold in a wind turbine where would you use it?

admin answers:

Gold are good conductor of electricity, and sometimes it will alloy it with copper for semiconductor devices, gold are not good in turbine blades or same, because of the brittleness against high torque force, it is also not advisable in generators and rotors, they are not enough to produce magnitic force to convert it into electrical energy, it also not advisable in the construction of the tail and the tower, you need enough strength to the carry the whole weight of the wind mill, and the most number one reason is……………. It is too expensive to construct a huge wind turbine made of gold

John asks…

How can i do a wind generator that creat electricity for a science fair project?

Hi, my teacher told me to create a wind generator for my science fair.Its not only doing the wing generator,no, i have to make electricity with it, like i get a bulb and it had to turn on with out batteries, only with the wing thing.Can someone give me like a web page or something that could help me please. HELP!!!!!

admin answers:

I think you mean wind turbine. A wind generator would generate wind, ie, an electric fan.

Look on line, there are dozens of possibilities. Search google for “school wind turbine”. Below link is one of the results.

Your Questions About Wind Turbine Syndrome

Joseph asks…

Isn’t it time to face the truth about wind power?

Wind turbines are very expensive to build and install, and maintenance costs are ridiculous. They kill thousands of birds and bats, are aviation hazards, and are so noisy that even the environment-minded Kennedys blocked the construction of a bunch of them on Cape Cod. They even cause a disease called Wind Turbine Syndrome in people who live nearby. Now it turns out that wind farms cause climate disruption as well. On top of that, it has been proven that “mathematically windmills are completely unsustainable” (see link below). So–shouldn’t the politicians look at the facts and stop spending our money to promote a technology that is profoundly stupid?

admin answers:

None of the above is totally factual. Bird kills? Some, but high rise office buildings kill thousands, as do pesticides, herbicides and house cats. While building wind turbines ain’t cheap, they’re far cheaper per kilowatt hour over X years of operation than coal burning plants when ALL of the costs over 5/10/15 years are considered. Maintenance as per hours of operation divided by hours under repair per unit is less than coal plants when again, all of the supply tail and disposal issues are factored in. It wasn’t the ‘Kennedy’s’ alone that were opposed to the Cape Cod project…it was everyone on that particular part of the east coast. Wind Turbine Syndrome? Try living down wind from a coal plant.

Here in the southwest we have sun AND wind almost everyday. Even on the ‘calm days’ the sun shines bright and on the few really cloudy days the wind blows at a steady clip. In the mid west you can count on a lot of wind. We’re talking about at least 1/3 of this country that could get by with only a minimum of coal or gas burning power plants. Of course that would cut a massive hole in the coal industry and the coal burning power plant companies…so of course they don’t any part of 21st. Century technology. 99% of the propaganda against solar and wind is exactly that…propaganda to save a 19th century technology from going extinct.

Lizzie asks…

Wind turbine syndrome? Infrasound?

Apparently those huge wind turbines can give off infrasound (sound >20 Hz) which causes a lot of things like nausea, problems sleeping, difficulty concentrating etc. What i am wondering is do they ALL give off this and if so at what distance from them is the infrasound at its prime? I would like to find out also is there a way of producing infrasound at home for the purpose of experiment to see if it has any effect (as some people are apparently more affected than others) and has anyone had any bad experiences with it?

Thanks 10 points.

admin answers:

I quote
“With regard to effects of noise from wind turbines, the main effect depends on the listener’s reaction to what they may hear. There are no direct health effects from noise at the level of noise generated by wind turbines. It has been repeatedly shown by measurements of wind turbine noise undertaken in the UK, Denmark, Germany and the USA over the past decade, and accepted by experienced noise professionals, that the levels of infrasonic noise and vibration radiated from modern, upwind configuration wind turbines are at a very low level; so low that they lie below the threshold of perception, even for those people who are particularly sensitive to such noise, and even on an actual wind turbine site.”

See link for the rest.

If your ‘source’ is anything other than the usual ‘scare mongering’ by the no-nothing morons of the gutter press, by all means counter this conclusion ..

Your Questions About Wind Turbine Generators For Home Use

Sandy asks…

Make electricity with steam at home?

This is probably a silly idea but I really like the idea of making my own electricity. I’ve thought about solar and wind but neither would really work for me. My wife & I will be building a new home in 9-10 years and I have a new idea…. We want to have one of those outdoor wood burning furnaces to heat the house. Is there such a thing as a small steam powered electric generator? If there is, maybe I could use some of the heat generated in the furnace to boil water, make steam and turn a small turbine to generate electricity. This way, I could heat my home in the winter and make my own electricity all year long just with wood. Just an idea (maybe a stupid one). If anyone has any info on this subject please share it with me. Thanx.

admin answers:

The killer here is efficiency. The efficiency of a steam turbine is only on the order of 30%. The equipment is pretty expensive too unless you go with some kind of home brew set up which can be dangerous. You would need to burn a lot of wood to make any serious amount of power. It would probably be cheaper to buy from the grid.

Chris asks…

How can I start a wind turbine Business and where is a good place to look for grants?

admin answers:

The energy efficiency sector will skyrocket the next few years, so good choice with that!

Wind farms are starting to pick up attention from the general populace due to the dwindling supplies of fossil fuels and their rising prices, which in turn contribute to the rising power expenses. The use of fossil fuels to generate electrical power is also unfriendly to the environment because of the pollutant nature of fossil fuels.

There are two reasons that people may want to invest in wind power. First, to save up on power expenses by relying fully or partially on wind turbines to derive electricity; Second, to become more environment friendly. No matter what the reasons may be, you can take advantage by setting up a wind power business.

A Good Location for Wind Farm Business

The first thing that you have to ask yourself when planning to engage in a wind power business is, Do I have the right place to harness the power of the wind? Household wind power systems do not need to worry about this since their power requirements are minimal, but to be able to feed houses you would need to produce a lot of electricity. The best place for this is a location where there is plenty of breeze to turn your windmills, like near the shorelines as well as high places.
You Need Windmills

Windmills or wind turbines are the driving force behind wind power systems. It is through these turbines that the wind is used to harness electricity by using the kinetic energy generated by their turning motion. The motion is initiated when wind is blowing the turbine panels. No matter if the wind blowing is a breeze or a gale, the motion will continue to harness kinetic energy and convert it into electrical energy.

Wind turbines used in a wind farm can either be commercially made or made at your own home. Buying commercially means you can get high-quality turbines, but would cost a lot to buy and install. Using home-made turbines, on the other hand, would require a bit of work by hand but are cheaper. Materials for home-made turbines can cost you only by the hundreds, while commercially made windmills may cost you thousands to acquire.

Power Lines

If you plan to invest on a wind power business, you would need to be like the big-time power distributors and install power lines from your windmills or power source to your clients. Fortunately, power distributors nowadays also buy power from independent power distributors whether they are using natural power sources or fuel fossils. As a windmill power generator, you are in line to become one of the power distributors feeding power to the local power company.

Your Questions About Wind Turbines Colorado

Laura asks…

Should the brightest mind in the world be focusing on solving the pollution problems?

With all the health issue’s tied to smog and the eviromental impact from smog, Shouldn’t we be making this the highest priority to fix? Many of you may not know about the seriousness of the pollution from coal burning plants and we have solutions to fix it but it is moving slow also the burning of petroleum fuels should be fazed out the sooner the better because they just can’t be made clean. All this pollution ends up in the ditches then streams then rivers and lakes and it doesn’t have to be that way. If we have the solutions then why not move on to the future and live in a cleaner world?

admin answers:

There are many very brilliant people working on many different aspects of “green” technology. Solar energy and biofuel research has been going on since the ’70s (although poorly funded from mid ’90s till recently). There is a national lab dedicated to renewable energy in Colorado ( and other national labs like Sandia and Oak Ridge also do research related to greentech.

There is also a very large new center opening at Berkeley called the “Energy Biosciences Institute” which is partially funded by BP. Contrary to the previous response, ignoring the environment is only in the short-term interests of corporations. In the long term, even they need to be concerned about the problems that have been building, and some of those with more forsight are beginning to take the lead in putting more capital behind greentech – it is in fact, a great business opportunity.

The problem is that solving these problems isn’t like a moon-shot. We can’t put tons of resources into a single program and expect it to find “the answer” to pollution. We need renewable plastics, green chemistry, improved agriculture practices, biofuels, thin-film solar, blades for wind turbines, more efficient engines/turbines, lightweight materials, redesigned transportation infrastructure, better power grids, eco-friendly architecture, AND ways to retrofit all the fancy new stuff into our current reality.

Maria asks…

Do you think all new build houses should have solar panels fitted?

Don’t you think it would be a good idea if the Government made it compulsory to have all new build houses fitted with solar panels? If everyone had solar panels, the price of them would come right down.
What do you think?

admin answers:


Simply, not every house will be a compatible match for solar.

Solar needs sunlight. If a roof surface is not in the correct 40 degree sun path facing magnetic south, then modifications have to be made to build up and angle panels so they do. This can cost more than the energy ever produced for the home. That is an unfair burden to add those costs to that homeowner. The ideal home will face south with a 40 degree pitch to the roof. Can you imagine every house from here forward with a plain gable roof all faced south?

In addition, trees could become an obstruction. Planting designs would have to eliminate any tree that would grow higher than roofline and shade the panel array. Passive solar methods like tree lines have been used for years to help summer cooling costs.

Geothermal systems are working very well in Colorado which suffers severe weather mood swings between hot and cold. A new energy efficient home built in the foot hills just proved its capabilities. The annual heating costs for this 2000 sq foot home was $34.00. Yes, $34.00 for the entire year. That system also heats the water used to bathe and shower in.

The cost of that system paid for itself in the first 2 years making this one of the best investments on the market. I say skip the stock market! Homes, including those in the City, can be designed with either a horizontal or vertical system.

Eastern Colorado is finding great success with small wind turbines making them more affordable than a typical solar panel array.

At this point, no, I don’t see this becoming a mandatory situation. But, the solar manufacturers have been supported and are working for grid autonomy meaning the panels should be as cost effective to install as hooking up to your local power. The solar industry knows it has to become more competitive. It’s very survival depends on it and we are already seeing drops in pricing.

Let me point out that Solar is still a good return on investment “for the right house”.

The energy efficiency approach is based on Best Practice. That means, one system like solar will not work as the solution for everyone. Building codes like plumbing and sanitary systems are because of safety and health reasons but they dont mandate this product or that product. Just that the products must be safety tested to meet certain standards. They do mandate that solar follow NFPA and NEC codes (National Fire Protection Association and National Electric Code) and be installed by a Master Electrician… Again for safety reasons. Geothermal be installed by a licensed Master HVAC and a Certified driller. For, you got it, safety reasons.

Lisa asks…

How can I make a composite material to build wind turbines with recycled material?

My father and his friends are trying to start a buisness building wind turbines, and we have been trying to figure out a good material to make them out of, that we can use recycled material Eg. milk jugs, cans, etc.
We have almost every resource you can think of and lots of different machines to work with. Cranes, everything.

Any suggestions would be very helpful, the reason they’re doing this is because they are being laid off as millwrights.

admin answers:

Its so hard to find good materials for wind turbines. Manufacturers of wind turbines use very specific materials. But if you want to build one for you from recycled materials, its good but efficiency of turbine will be very small. I build one wind turbine from plastic pipe :

Your Questions About Wind Turbine Technician Jobs

Sharon asks…

what industry has more growing jobs and is growing faster?? wind turbines or solar panels?

I wanted to get training as a wind turbine technician but i’m wondering if maybe a job in solar panels is a better choice. And I live in southern california.

admin answers:

Firstly, your very lucky there in california as either way would actually be pretty good.

Solar will be bigger than wind for many years to come as there are many more companies investing in solar panels as they require a lot less maintenance. This could be a good reason to go into wind, More money, less work. Being in california you may have enough work either way. Maybe do both? Might sound weird but there are many companies employing people that know about both. Solar companies that want to expand into wind but cant afford 2 experts might want a join expert.

Linda asks…

What are some high paying jobs with dangerous aspects? (Fearsome aspects, fear, potential danger, etc)?

Long ago I discovered the job “Wind Turbine technician“, which basically involves greasing the turbines and perform regular maintainence while receiving 14-25 dollars an hour. The job doesn’t seem too rigerous, but the fact is that these technicians operate from a terrifying hight which intimidated the reporter interviewing the technician. Obviously the job requires additional education, but even with that aspect there isn’t any availability in my state.

I’m not sure what the term is for these types of jobs, but it seems very appealing to me

admin answers:

Dangerous jobs include working on our power-line workers, crab fishing, timber cutter (lumberjack), structural metal workers, farmers and ranchers, miners, roofers, truck drivers, and fishermen. This is a list of careers that record the most fatalities annually and they all pay more than average because of that.

Your Questions About Wind Turbine Syndrome

Carol asks…

After seeing videos like these, do you still think more wind turbines are a good idea?

Or are they still good until they are brought into your own neighborhood?

Headaches, dizziness and nausea cause by the unnatural “flicker effect” of the giant shadows cast by the giant turbine propellers:

People being forced out of their homes because of health health problems cause by “wind turbine syndrome” caused by the flickering, EMF energy pollution emitted, noise, and vibrations.

Maybe I’m more sensitive than some, but even seeing videos of wind tubines spinning and causing blinking lights makes me sick.

admin answers:

The flicker effect is annoying. Maybe the agw socialist hippies would like to live in the shadows of wind turbines because they’re a bit like disco strobe-lights. They’re already dizzy and nauseous in promoting global warming.

Seriously, wind turbines have a role to play in isolated areas where generating power is a problem. But they’re expansive, expensive, ugly on any landscape, noisy and only work when there’s enough wind to make them turn. The idea of building them to power large communities is scary, and now apparently they lead to health problems. My opinion is to use them only where other power sources aren’t practical/possible.

I’ve seen a lot of electrical plants and I would rather live near one of those if I had to choose. Seeing these giant EMF towers with their spinning propellers makes me sick, don’t they make you sick too?
It Girl: I agree–when you look at them they stand out as not belonging there. As being unhealthy and unnatural.
piegowdealer: The third video is in the US–Oregon.
And I’m not against clean energy at all–I still think electric cars are a good idea. I just think fake “clean energy” schemes/scams are bad ideas and bad for our health.

admin answers:

Hmm…strange, because we have wind farms where I am and I have not heard of this. At all. I have not felt massive vibrations, I have never seen shadows that large cast anywhere near residential housing, and I know of no animals who have suffered dangerous reactions to the stimuli. I have never experienced hearing much noise from them either. It isn’t like you can compare a wind farm with an international airport, a train station, a bus depot, a nuclear energy plant, an oil rig, a coal processing plant, a shooting range, a major waterway, a large city (more than a million), barges, lock and dams, a major grain plant, rendering plant, hog or chicken farm, or distillery (they all smell to high heaven) or even a military base where they set off ammunition–all of these are way worse (trust me–I have lived near all of these items at some time or another in my life).

If you do not trust my accute assessment (since I am not a scientist or an energy advocate of any kind), then try reading up on the views of wind energy from communities that have lived with it for many years. You will find that the level of satisfaction in this method of energy production is superior to that of energy created by other methods. Not everything you see on youtube can be trusted as comnplete fact–if you believe everything you see on there, then I would be worried. As for them not being attractive…well, not everything can be aesthetically pleasing, now can it. If you can’t seem to live near it, then move–people do it every day, especially when they live near noisy or obstructive things (airports are a great example). Otherwise, get over it–unless we want to spend billions of dollars in solar panels, or geo-thermal energy systems, this is one of the cleanest energy solutions we have available.

Your Questions About Wind Turbines Colorado

Daniel asks…

What part of Colorado is best to live in?

I need help finding the best area to raise a biracial family in Colorado. I would like a town that is reasonable and has little crime and good job opportunities. I am African American and my husband is hispanic. Thanks!

admin answers:

If your husband is of hispanic heritage, I would reccomend Pueblo. The population was close to 45% Hispanic at the time of the 2000 Census, and has likely grown to 55-60% over the last decade.

Jobs in Pueblo, however, are hard to come by right now as they are everywhere. There is a new plant, “Vestas,” a manufacturer of wind turbines that is being built south of town and scheduled to open later this year, but they have had close to 10,000 people apply for only 500 jobs.

One thing you have to be aware of in Pueblo are high-crime areas. I would strongly reccomend staying away from the Bessemer area, as well as certain parts of the East Side and West Side.

There are several neighborhoods in which you will be able to find decent housing at an affordable price, such as Belmont on the city’s northeast side, and several areas on the north and south sides of town.

Pueblo West (another town about 10 miles west of Pueblo proper), University Park, also on the city’s northeast side, and the Regency, Southpointe, and El Camino/Ventana areas on the south side of town are low-crime areas, with very nice, but very expensive housing.

Pueblo has an average school system, I can’t really tell you which elementary schools are the best, but i can tell you about the middle and high schools.

Good middle Schools: Heaton, Roncalli, and all Pueblo West middle schools
Average: Pitts, Freed
Bad: Risley
-There is also one Magnet School on the city’s south side.

Good High Schools: South, Centennial, Pueblo West
Average: Pueblo County
Bad: East, Central

Hope this helps.

Susan asks…

Can anyone shed light on the Colorado oil shale situation?

Will the extraction EVER begin? Once in a while this story pops up about the Rocky Mountain oil shale. I’ve searched for info but I usually only find adds for investment ops. I have no interest in investing, but am very excited about the prospect of the US becoming the dominant oil power. Is this ever going to happen, or are we too concerned with the already doomed environment to do any more drilling? Any info with a source would greatly appreciated

admin answers:

While I’ve only seen the investment ads – this is my take on the situation. The US has HUGE natural resources that aren’t depleted – coal, oil shale and oil. However the environmental groups and townships block exploration and extraction of resources. (Not in my backyard – as the mantra goes). The technology for burning oil shale is not 100% completed yet – the process needs to be refined anyways as it takes alot of heat to refine it . The country basically needs a disaster so spectacular to consider doing any major projects that can have environmental impact (hance not drilling for oil, or even setting up electric generated wind turbines off the coast of Mass.) Sorry I can’t give sources. Check out wikipedia on it.

What do you call a structure that captures the wind and turns it into energy?

A. Windcatcher
B. Energy Blow
C. Windmill
D. Wind generator
E. Wind Sock

admin answers:

It is properly a “wind turbine.”

Vestas, GE, and Gamesa are the three largest manufacturers, and they all call them wind turbines.

A “wind catcher” would catch wind, but not use it to make electricity.
A Energy Blow isn’t describing anything.
A Windmill manufactures SOMETHING with wind–but it may not be electricity. (It might pump water, as in a Dutch Windmill.)
A ‘wind generator’ would make wind. (Think grandpa!)
A “wind sock” is used to determine only the direction of the wind.

Where can I purchase a residential wind turbine, preferably horizontal in the Chicago area?

I just moved into a split level home in a suburb of Chicago. I was thinking of either installing solar panels or horizontal wind turbines on the roof of my porch. Any help in finding companies for this would be appreciated, I am more interested in wind then solar being that Chicago is pretty far north (little sun in the winter) and known for our wind.

admin answers:

Search and network on the tree hugger and ‘mother earth’ websites. They will probably have info on residential wind turbines. Companies aren’t really interested in marketing residential turbines because the money is in commercial energy production and that is where the resources go. But their are probably some made in the garage type industry out there that has what you need. And good luck finding something in the horizontal variety.

Paul asks…

How does a wind turbine generate electricity?

im making a diagram upon how wind turbines generate electricty
so please help me to like create. i know the wind turns the blades which creates electricity via the generatore. but how does it occur.
what type of energy is used. EG kinetic, thermal?

/thank you xxx

admin answers:

A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind turbine generator (WTG), wind power unit (WPU), wind energy converter (WEC), or aerogenerator.

What can you tell me about wind turbines that move vertically or in a helix shape?

Our town is considering purchasing several of these types of wind turbines. I am on the youth advisory board and we think it will save us time and money as well as a cleaner, more efficient source of energy. Links, videos, and any other information is greatly appreciated as well as your general imput. Thanks!
Overall, do you think this would be an investment or a waste of money. (We would receive grants, fund raise, etc…)

admin answers:

Kinda depends…. Are you getting a contractor to show-up and install it, or is the project being done by locals? That is who is responsible for design, fabrication, installation?
If this is to produce electricity, are the generators a direct to grid design or will there be inverters?

Send me individual email, I’ll discuss this with you, if you are interested…

Given “grant $” this could be a win-win, HOWEVER, has anyone checked on the MTBF figures for the sort of wind plant that you intend to install? There are things that could make this a GREAT investment and there are factors that could end up costing your town a LOT of $ for no benefit at all.
I have no idea, how much or what sort of research has already been done. …. What?

Your Questions About Wind Turbines For Home Use

Donald asks…

Are wind turbines for the home beneficial?

I would like to learn more about the subject as I read not long ago that you can save money by installing wind turbines in your home. Are there any real benefits? Is it expensive?

admin answers:

Yes there are many benefits.
Using the wind to generate energy will permit you to be less dependent on fossil fuels, which are non renewable. So you will actually be helping our environment.

Also, there is the economic factor, you will save hundreds each month in electricity.

If you are going to buy a wind turbine for the home, be prepared, because they are costly. A solution for this would be to build the wind turbine yourself. Here I provide you with a link that has more information about that subject.

Your Questions About Wind Turbines Oklahoma

John asks…

do windmills use electricity? i thought they provided electricity. we have plenty of wind in oklahoma!?

admin answers:

Wind turbines actually do consume in their normal operation. The turbines have complex control systems which control blade pitch, sensors, metering, etc, all of which consume power.

When the turbines are up and running in optimal conditions, they will produce more electricity than they consume. However, in low wind or no wind, they can be consuming more electricity than they produce.

You can think about it the same way as a normal power plant. The plant building has lights, controls, pumps, fans, etc. All of which consume electricity. When the plant is running, the building will be supplied by the plants generators, but if the plant is shutdown, the building still consumes electricity and must get that electricity from the power grid.

Don’t find it ironic conservation?

Don’t you find it ironic that places with the most unique fauna, had bad conservation efforts and there animals are endagner. For instance china has unique faunayet have only 10% of land remains and that is fragmented, a lot of it species are either endagner or extinct in wild ( south china tiger, giant panda) and India 2 home to half worlds tiger yet there conservation efforts suck. There barely any land left and tiger population has declined 95% in the last 100 years same goes for the rhinos in asia. There barely a 1000 and that was a decline of 99% in as little as 200 years.The only thing they did do right is making the asatic lion population go up. Oh lord and don’t even bring up Africa.

Iowa has maybe 1% of its wetlands and 1% of its native prairie left intact, and it is fragmented and scattered all across the state. People tend to only care about charismatic megafauna.

I agree that there are some major conservation problems around the world. In poor countries, it is largely due to poaching. However, it’s unfair to point a finger squarely at them and deride them for not caring and being destructive. We build suburbs, we drain rivers because we have to water our lawns, etc and so forth. It’s completely under the radar here. There is a river in Oklahoma (The Blue River) that is being heavily pursued by OKCity and TX for water rights. It is truly a gem, a clear, aquifer-fed stream in the middle of an area with house-sized boulders that are 1.4 BILLION years old. Every other river in this area is muddy and a complete contrast.

How can people not stop this? How can people not protect this river that has darters and other beautiful fish? They don’t even know about it. People get so caught up counting carbon and putting wind turbines where they shouldn’t be that they are blind to the issues right under their nose. Don’t get me wrong, carbon-counters and other green folk have their heart in the right place, but the true irony is that there is an environmental catastrophe every other day in their own backyards.

Wind Power

Wind Power is an interesting concept and design that converts energy from the wind to a more useful form of energy. The use of wind power has roots in the ancient European flour mills and the American water pumps. Wind turbines are the most commonly used tool of conversion and the wind power is most usably converted to electricity.

Dating back to as early as the first century AD, man has been using wind power to generate energy. European flour mills utilized the efforts of windmills, as did the American farming and ranching industries.

Large wind farms help to convert large amounts of wind power into usable energy to help power local areas. Some countries have found ways to utilize this excellent energy source to benefit their growing populations. Today, Denmark uses wind power to accommodate approximately one fifth of its total electricity production. Across the world, wind power generation is increasing exponentially and is beginning to be seen as a great renewable energy resource.

Wind power is environmentally friendly, world-wide, and highly renewable. As far as renewable resources, greenhouse gases, and environmental hazards are concerned, wind power is an excellent alternative to fossil fuel derived electricity. However, wind power does begin to come under fire when the topic is the location of the large and sometimes unsightly wind turbines. Situated in the best wind sites, these modern looking structures tend to devalue the scenery and natural landscape.

Today, there are thousands of modern wind turbines in production all over the world, and as of 2004, wind power was the fasting growing energy resource. With the global community focusing on more environmentally friendly energy options, the use of wind power is becoming more and more prevalent. Although the United States is not the highest converter or user of wind energy, it is adding more of this renewable energy to its power grid than any other nation in the world.

Apart from the international community and large scale use of wind power, more individuals are beginning to see and seek the benefits of small wind generation systems to power their homes and small businesses. On such small scales, wind power is highly cost efficient and clean.

Although wind power has a lot of potential, the logistics of its use are debatable. Wind farms tend to develop at sites in remote locations, which significantly increase the cost of production due to transport costs, and no one can fully be sure of the direct or indirect environmental damage of the proliferation of wind power. Despite the theoretical consequences, wind power conversion is on the rise and will be for years to come.

Your Questions About Wind Turbine Syndrome

Donna asks…

Should environmentally sensitive people have fewer children, or more?

Environmentally sensitive people understand the pressure of burgeoning human population on scarce resources. Water shortages are already a reality that affect billions of people, and the need for more farmland and wood conspire to destroy habitats that are not merely exciting and unique, but that might hold answers to questions we are only beginning to ask.

It seems that environmentally sensitive people should take the lead and have smaller families–or no families at all. If ‘we’ do not start the process, who will?

But then again, such a strategy will reduce the most direct impact environmentally sensitive people can have on the next generation–their own children. Perhaps the most effective strategy for populating the world with more environmentally sensitive people would be for ‘us’ to have more children. Otherwise, the world might be overrun by ‘them.’

What’s a sensitive person to do?
Not a problem for America in the 1960s, Ardi, but the global problem was recognized 150 years earlier by Thomas Malthus.

JackP, Malthus also recognized your ‘solution:’ don’t worry, nature will solve the problem. My concern is that ‘natural solutions’ tend to be extraordinarily violent. Can’t we humans, who understand the problem and can anticipate the natural remedy, do better?

admin answers:

In the US, environmentalism came to the fore with the hippie generation. It was also the hippie generation who promoted Zero Population Grown, and we achieved it with tremendous success, if you can call “success”.
1. There are fewer people to buy American products and services, so our economy is not growing like that of China and India. Even with the “one child” law in China it is growing too fast to keep up and soon it may have to say “No children”.
2. With fewer young people than people who are growing old, the young cannot afford to pay for the entitlements given to them by their own grandparents generation, namely Social Security and Medicare.

A growing population was not a problem for America when the hippies (I was in that generation, but I was more conservative) promoted ZPG. They say right now the entire population of the world could fit into the borders of the US, or into even less space. But those same environmentalists are at odds with each other over how to solve problems. On the west coast where there is oil, they are saying no new oil rigs; in New England where there is wind, they don’t want wind turbines out in the ocean. Obama wants electric cars, but that will only drive up the demand for electricity and we are not building any new power plants. If we built pebble-bed nuclear reactors we wouldn’t have the China-syndrome problems and no spent fuel rods to dispose of, but those safe reactors are against American laws. Http://

Helen asks…

Are Wind Turbines a Greater Health Hazard than Nuclear Power Plants?

Thousands of people living near wind farms are suffering from symptoms collectively know as “Wind Turbine Syndrome“.

Also wind farms adversely effect property values, reducing many home owners equity by half.

Compare this to nuclear power where no health complaints have been filed, and property values are not effected.

Does this prove that wind farms pose a greater health hazard to people than nuclear power?

Would this be a good reason to develop more nuclear power and less wind power?

admin answers:

Sorry, Doctor, but I’m going have to be sceptical on this one . . .

The article you link to refers to The Independent, the newspaper for the ethically right-on “modern parents” type of middle-class worrier who loves nothing more than an environmental scare with their cornflakes in the morning.

It was The Independent who, the day after the Asian Tsunami struck published an article linking it with global warming. People on BOTH SIDES of the debate should not trust this paper.

Your Questions About Wind Turbines Oklahoma

Robert asks…

Turbines or ridge line vents when you have a smaller home?

I’ve asked a lot of questions about this and I do apologize, but I had a roofing company guy say that in my state, Oklahoma, where it’s so hot having turbines (whirlibirds) is better than ridge vents because our wind makes the turbines really work and get the heat out, and also the fact that my ridge line isn’t that long (?).

I hope that makes sense?

My house is only 1200 sq feet and I have soffit vents and all the other companies just put ridge line vents (2) in my estimate, but this one guy said he liked turbines better.

Just wanted to get opinions.

admin answers:

In your part of the country ridge vents should be adequate. Do be sure the insulation is pulled back so that your soffit vents are uncovered. Turbines are one more hole in your roof and moving parts that can wear out. If you’re getting shingles be sure they are the architectural type and not the old three tab design. They will stick to the roof much better when the Oklahoma winds are howling.

Daniel asks…

At what point will farmers convert grass lands to….?

I was driving threw Oklahoma and Texas (on I-40) last week and thought… “Hmm, this is a pretty barren place… nothing but cattle and grass and the occasional wind mill… why not farm the sun”. And seriously? Why not throw up a couple acres of solar panels with a power meter that lets you sell it back to the power companies? Do you think this may be a future cash crop? 😛

I’m only halfway serious 😛 But seriously, what are your ideas for our future energy needs?

admin answers:

You are actually on to something. Those long, sweeping plains are also good potential locations for wind turbines. In fact, I once heard someone say that the Dakotas are basically “the Saudi Arabia of wind power”.

To answer your question, these things (solar, wind, etc) will happen when it becomes economically feasible to do so. With oil going up and up and up, that day may not be so far down the road.

Your Questions About Wind Turbine

Lisa asks…

What is the monthly yield on a 60K wind turbine if it’s planted in a wind farm?

I want to purchase a 60K wind turbine and plant it in 29 Palms, CA wind farm. If all the electricity produced is returned to the power company, what would the monthly yield be?

admin answers:

Typically in 29 Palms, you get 8 hours of good wind per day (four hours in the morning, and four hours as the sun begins to set.) The wind speed needs to be around 25 mph to produce sufficient wind to generate at maximum capacity. You’d produce 60 kilowatts of electricity for about 8 hours a day with a 60k wind turbine. That is 8 hours*60 kw, or 480 kw/h. You’d sell that power at about $0.08 per kw/h, so you’d get (480 * $.08=) $38.40 per day from a 60k wind farm. You’ll see soon, as you do the math that it doesn’t justify the cost, unless the wind turbines are HUGE. (Remember the formula for calculating the area of a circle is pi times the radius squared.) The blades need to be large enough to overcome the ratio of the cost of the blades, and that works out to be about 80 to 100 feet long. If the blades aren’t that long, you won’t get the project to pay for itself (without tax subsidies or some other income.)

Now, building even one really big turbine starts paying off spectacularly: but it will be measured in Megawatts, not kilowatts. A GE 1.5MW machine pays for itself (cost is about $2,250,000.00.) There are other manufacturers building at that size and scope too, but GE is a good example.

A GE 1.5MW machine using the same math earns the owner 1500 kw * 8 hours * $0.08 per kw/h = $960.00 per day. In a 365 day year it would generate $350,000.00 per year, and pay off in about 6.5 years. (In actual practice, give it 8 years, because there are Operation and Maintenance cost issues that you must pay for: Someone has to oil the machine!)

Your Questions About Wind Turbine Generators Australia

Robert asks…

Should Australia increase the use of turbines to generate power rather than relying on fossil fuels?

I would like also like to know if it is possible to run the whole of Australia, or South Australia let alone, only on wind energy, provided that Australia has enough material, money, land and turbines?

admin answers:

We already get our power from turbines, being steam, water and gas turbines. You mean wind turbines I guess. The southern coastline (Great Australian Bight) is a good wind zone I understand, so lets say it will produce 25% of the capacity of the wind turbines over a year. The UK achieves about 23% it is claimed.

Very large turbines are rated at say 5MW and might produce around 1.25MW on average.The size is 65m (each blade) and spaced 5-15 diameters apart, especially considering the row behind receiving the wake. This depends a lot on the land itself, but would look like 120m x 15 = 1.8km spacing which may be best for cost recovery with these very big generators. If the Nullarbor plain is taken as 1000km that only allows a row of 500 along the coast at most, with an average production like 625MW for the whole row. There can be multiple rows, but I have no idea how many are feasible. This whole row is similar to a single large coal fired steam turbine generator (600MW) A steam power station may have several of these. However there are other significant infrastructure issues, like the concrete used amounting to 1300m^3 each, the roads and the electrical distribution needed to cover long distances, how to replace or recycle all this. There is a strong likelihood that the grid needs an on line standby system of the same capacity, as well as a great increase in its carrying capacity in certain areas. This standby can be hydro (there isn’t anything like enough), though pumped storage could be built on some mountains far away (no mountains on the Nullarbor) or a bank of large gas turbines on line using methane or kerosene etc. Steam (coal fired boilers) generally cannot respond to sudden large changes in load if the wind drops.

The Australian production in 2009 was 261 million megawatt hours (second link). One row of generators as above would be around 5.5 million MWh a year, so it needs about 50 rows, stretching 100km inland. I am not sure the wind holds up that far even without 50 generators in the wake of each other.

This is a very rough estimate, but it seems to me it is not a very practical thing at all. Think of wind power as a fuel saver, something that is only useful in specialised areas like the southern coast line. In the tropics with cyclones and little winds otherwise to deal with, forget it, with any current technology. Normal winds are “very moderate”, while cyclones are up to several times the maximum rated speeds, and above the survival speeds. There are certain carefully chosen spots that do have wind generators in the tropics though I suspect these are more about political will than hard economic reality.

In the US estimates are that 20% of energy needs can be met by wind power. Australia could well be less than that. It may be one of the more expensive forms of providing energy, and not so clearly saving anything at all when all things are considered. The first link doesn’t have a positive view on these developments in Wales (UK), where politicians legislated that wind is the in thing. Politicians have law and art degrees. No surprise they make bad decisions about engineering, as they cannot tell who is stringing them along.

The second link might have other info of interest about load variation (change in demand) and aluminium smelters and refineries, and little known facts about the grid which appears to go to about Ceduna at the moment, so only the eastern part of SA is on the grid. WA has its own isolated grids.

The coal stations produce 78% of electricity and 200Mt (megaton) of CO2 a year of the estimated 30-35,000Mt of additional man-made CO2 a year in the world (according to the climate people). Where is the problem, one would ask. We export about 9% of this electricity as refined metals, with stuff like aluminium., and about 3 times as much coal as we use, also used for overseas electrical production in various countries that would be in a difficult position without it.

At present a mix of various energy types seems the best approach, with different situations in different locations. The best argument in favour of alternate energy is sustainability in the long term, but it seems that it will be very expensive compared to coal, close to Australia’s biggest asset. Should we just throw that away? Incidentally the alternative energy to suit Australia might be solar thermal.

Ruth asks…

Can a convection current turn a power turbine?

I’m curious whether a convection current, like heating through a tube, would be strong enough to turn a turbine that would be able to produce power? (In case you’re wondering, yes I do have an idea in mind, but I don’t know if it’s practicle yet.)
How much of a thermal raise do you think would be needed, and how much of a tube for, let’s say a 1kw generator?

admin answers:

Like the others say, it’s possible.

In June 2006, an agreement was reached to develop a 50MW solar tower generator, in which the sun heats air, which drives a turbine in a chimney, in New South Wales in Australia. The idea is not based on radically new technology. Chimneys with ‘smokejacks’ in which a fan in the hot air turned a roasting spit were certainly in use in the UK in the eighteenth century and probably before. It is well known that a tall chimney produces a better draught, presumably because there is a greater temperature difference between bottom and top, wind speeds are greater higher up, inducing more air to be drawn out of the top of the chimney by Bernoulli effects, and a long distance up the chimney should help hot air build up speed and kinetic energy.
But modelling all these effects and producing an optimally efficient design seems to be almost impossible, at least we have so far been unable to find anyone to take the task on.

If you are using a fluid medium, it could be more possible to make. Implied in your question though, is that we are looking at a vertical model for the turbine since you want to draw on the heat differential between a cold medium and a hot one.

Your Questions About Wind Turbines Oklahoma

Mark asks…

where is wind energy used?

where is wind energy used?

admin answers:

There are areas around the world that are famous for their strong winds.

Wind turbines tend to not be economically competitive unless they are located in these strong wind areas.

With wind energy if you double the speed of the wind you square the amount of energy available

The areas in United States are well documented by the National weather service and other government agencies. The wind maps provided by these agencies show an average watts/ sq meter of wind power available on an yearly average power basis.

Most of the wind areas lie in the flat plain areas of central united states like texas, oklahoma and kansas. There is also great wind areas off the atlantic coast in the new england states areas. There is also great areas in mountainous areas of all our ranges, the sierra nevadas, the rockies and the appalachians.

Most strong winds are either close to big bodies of water or wide open expanses of range land. Trees and low foothills and cities tend to slow air current speeds.

Your Questions About Wind Turbines Colorado

Paul asks…

Do you have an off-grid home in a cloudy, rainy climate? Would solar panels be worth it?

I’ve been doing a lot of research on places to live when I finish school, and I really think Oregon is the perfect place for me. Me and my boyfriend want to build an off-the-grid house. The thing is, he says we can’t live in Oregon because it’s not sunny enough, and if we relied on solar panels it wouldn’t work out. Is there some other off-grid solution besides solar panels we could use as backup? I don’t know much about wind turbines and how much they would cost. Does anyone living in a rainy, cloudy climate make much use of solar panels? Or should I move to a state that has more days of sunshine (I’ve been considering Colorado)? Suggestions? Thanks.

admin answers:

There are a lot of off-grid houses in Oregon, and many sell their power back during the sunny days to balance the rest of the time. Just do a search on green houses in Oregon to find some of the projects listed. There are also cob houses in Coquille that are quite interesting. But at present. It costs more to get these off grid houses built than they recover. Most folks just starting out can’t afford to do it.

I’m looking for ways and colaborators to take an existing house and pull it off the grid – affordably. Have lots of ideas, but little free time to play with doing them. Would love to share ideas.

Are there any government polices concerning wind energy?

I’m writing an essay for my college English class about wind energy and I’m required to include information about a government policy concerning wind, but I cannot seem to find anything. Any websites or helpful information would be greatly appreciated.

admin answers:

You can have a look and pick up some of the following points.

As the Obama administration creates the first U.S. Program to authorize offshore projects to generate electricity from wind and ocean currents, the President deployed the Clean Coal word yet again. We hope this is part of the Obama M.O. Of building bridges, getting buy-in and bailing our of a fool’s enterprise but with a new team of allies board. Link to the transcript below.

Obama said wind could generate as much as 20 percent of the U.S. Electricity demand by 2030 if its full potential is pursued on land and offshore.

“The choice we face is not between saving our environment and saving our economy — it’s a choice between prosperity and decline,” Obama said in his first post-election trip to Iowa, the state that launched him toward the White House. “The nation that leads the world in creating new sources of clean energy will be the nation that leads the 21st century global economy.”

The latest in the ongoing allocation of money coming out of the American Recovery and Reinvestment Act: The Department of Energy has announced that $93 million has been made available to support wind power. Here’s how that money breaks down:

$43m for Turbine Drivetrain R&D

DOE will provide $45 million directed toward enhancing the federal government’s ability to support the wind industry through testing the performance and reliability of current and next generation wind turbine drivetrain systems.

This investment will deliver dependable and cost effective hardware for utility scale wind turbines with over a 20 year design life. Overall, this project will help to improve the country’s competitiveness in wind energy technology, lower capital costs of wind systems, and maintain a high level of wind energy capacity growth.

$14m for ‘Technology Development’

To strengthen its support of the wind industry, DOE will make available $14 million to advance technology development in the private sector. This effort will aim to improve the quality and use of lighter weight, advanced materials for turbine blades, towers, and other components. Another area of emphasis will be process controls for lamination, blade finishing, trimming, grind, painting, materials handling and inspection.

$24m for Wind Power R&D

DOE will provide $24 million for the development of up to three consortia between universities and industry to focus on critical wind energy challenges. These partnerships will allow universities to establish research and development programs to advance material design, performance measurements, analytical models, and work with the industry to improve power systems operations, maintenance and repair, and component manufacturing.

$10m for National Wind Technology Center

DOE will invest $10 million at its own National Wind Technology Center in Colorado. This funding will enhance the National Renewable Energy Laboratory’s ability to support the wind industry through testing current and next generation wind turbine drive train systems for better performance and reliability. Additionally, upgrades to the electrical distribution system will permit cost recovery of the power produced by two new utility-scale wind turbines being installed there for testing and evaluation.
