Vertical Wind Power

Jenny asks…

Can wind power be mass produced?

hey, it’s me again asking for help :)
i need this for my global perspective homework.
oh yes, i need an answer to this question as well: Can WAVE power be mass produced?

Windmill Farms answers:

Drawbacks of mass production:
1. Comes at the expense of food production costs in most instances
2. Has intermittent electrical supply.
3. Noise and obstruction issues for migratory birds.
4. Requires fossil fuels to construct and maintain the wind farm infrastructure.

Tidal has been considered many times and has usually come up as uneconomic since you need a lot of equipment over a very large area to use (straight) wave power or a massive enhancement to the vertical rise/fall characteristics (read massive steel and concrete needs).

Richard asks…

Why do we have wind?

Rain helps things grow, sun helps them too. Why wind? Or better yet, why snow and frost. If someone could explain these I’d be at ease…

Windmill Farms answers:

Wind is helpfull in many ways.
Wind energy offers real environmental benefits. Wind power offsets other, more polluting sources of energy. That is important because electricity generation is the largest industrial source of air pollution in the U.S. When wind power projects generate electricity, fuel at other power plants is not consumed.
Wind energy requires no mining, drilling, or transportation of fuel, and does not generate radioactive or other hazardous or polluting waste.
To generate the same amount of electricity as does the current fleet of U.S. Wind turbines would require burning 9 million tons of coal (a line of 10-ton trucks stretching 3,400 miles, from Seattle to Miami) each year.
A recent New York study found that if wind energy supplied 10% (3,300 MW) of the state’s peak electricity demand, 65% of the energy it displaced would come from natural gas, 15% from coal, 10% from oil, and 10% from electricity imports.
Origin of Wind
Wind is simply the air in motion. Usually when we are talking about the wind it is the horizontal motion we are concerned about. If you hear a forecast of west winds of 10 to 20 mph that means the horizontal winds will be 10 to 20 mph FROM the west.

Although we cannot actually see the air moving we can measure its motion by the force that it applies on objects. For example, on a windy day leaves rustling or trees swaying indicate that the wind is blowing. Officially, a wind vane measures the wind direction and an anemometer measures the wind speed.

The vertical component of the wind is typically very small (except in thunderstorm updrafts) compared to the horizontal component, but is very important for determining the day to day weather. Rising air will cool, often to saturation, and can lead to clouds and precipitation. Sinking air warms causing evaporation of clouds and thus fair weather.

You have probably seen a surface map marked with H’s and L’s which indicate high and low pressure centers. Surrounding these “highs” and “lows” are lines called isobars. “Iso” means “equal” and a “bar” is a unit of pressure so an isobar means equal pressure. We connect these areas or equal pressure with a line. Everywhere along each line is constant pressure. The closer the isobars are packed together the stronger the pressure gradient is.

vertical wind mill moter?

i am making a wind mill for our chicken house to charge a car battery.
i am using a smart drive so will have to rewire it (i think) but i need to know if i should get one with the 0.6mm wire or 1.0mm wire???
ane also would like to know any other info u can give me thanks.
a smart drive is a fisher an pikal washing michine moter and it has been proven that they can generate power form a wind mill ect.

a smart drive is a fisher an pikal washing michine moter and it has been proven that they can generate power form a wind mill ect.

Windmill Farms answers:

Why would you want a motor?

You want a generator or dynamo that will generate DC power when it is rotated. A motor is the opposite, supply it power and it rotates.

Most motors cannot be used as generators. Only DC motors that have commutators in them.

What is a smart drive? That small difference in wire size won’t make any difference.


Donald asks…

Wind turbine installation advice for my home?

I am fascinated with the idea of using a wind turbine to provide power for my home. I like the cost saving part, but also the idea that I could be helping the environment too.

I’ve looked online and done a ton of reading and so far, it seems that that the only affordable way to install a wind turbine is going to cost a lot of money and I’d still have to build/install it myself and pray that I got it right. (Actually, I did read my local building codes and incentives and the local power company will come out and inspect it before you hook it up to the house and to the grid.)

I want to use one of those spiral turbines, as I think they are less obtrusive in a neighborhood setting and hopefully, I could install more than one if needed/desired since they are a slim design.

We tend to get heavy hard winds in the summer and I think I could rack up some free energy and possibly even sell back extra power to the local company too during these heavy windy periods we have.

I’ve seen free plans online to build them and honestly, they say they are simple and easy, but I don’t find them the least bit user friendly. I am above average intelligence, but I am no mechanical engineer!

Does anyone have any advice or tips on using/install wind turbines for home use?

Any suggestions on getting it cheaper? I am seriously thinking of trying to make a business out of designing kits or something similar that an average homeowner could manage to install for as cheap as possible.

Thanks ya’ll!
I recall seeing a DIY program where a lady had a spiral wind turbine mounted on the deck of her condo. The show wasn’t about it, but they did mention it. It appeared to be about 12 feet tall and maybe 14 inches in diameter… it was tucked in a corner away from most obstructions. When I’ve googles wind turbines, I still see the tradition fan blade types – I think they are too rustic for my neighborhood – the spiral one I saw on this show was much less of an eyesore.

I know that doing a wind survey would be a good idea, but if it doesn’t get wind all the time, and i’m still committed to it, does it matter if I do or don’t produce wind all the time. In times of our wind storms, could I produce TOO much?
When I’ve looked on my local power company codes, it’s pretty basic – no specifics on how much or little is required. My belief that even a little wind energy would be good – that is IF the price was right.
I am also checking out solar panels too as an option, but they seem very expensive and because of my roofs sun exposure, it’s not ideal – so I’m not sure i should consider it – but I’m not sure wind is 100% the right way to go either.

Any ideas/comparisions/considerations between the two?

Windmill Farms answers:

These types of turbines are very suitable to residential use. But just like any other wind power generators, vertical wind power has its advantages and disadvantages.

Verticle Wind Power!
Pros & Cons

1.It can easily catch the wind no matter which direction the wind is coming from.
2.It can consistently generate more power.
3.Vertical wind powers can operate in wind conditions having low velocity.
4.The generator can be placed in an area near the ground. There is no need to place it on top of the tower.
5,Vertical wind powers can be utilized in many areas as there is no need to have a tower built.
6,This type of wind generator is easy to maintain since its generator is located near the ground.
7.This machine is safe for flying creatures such as birds since the turbine blades rotates at a much slower pace.
8.There is no need to have a yaw system installed in the vertical turbine thus saving you money for buying yaw bearings.
9.Vertical turbines can easily be transported.

1.It is very difficult to install a vertical turbine in a location such as a tower.
2.Vertical wind powers are less efficient compared to horizontal wind power. Statistics will show that it can only generate half or 50% of the power which a horizontal turbine can generate.
3The installation has to be on a flat surface. It can’t be installed on a rough and steep surface.
4.Vertical wind power design is already old and outdated. It will be hard to find replacement parts if ever some of its parts are damaged.
5.Since it is installed near the ground, it cannot take advantage of the high velocity winds in higher areas.
6.Vertical turbines are very susceptible to vibrations.
7.It produces a lot of noise during its operation.

Lizzie asks…

monkey d dragons power?

i think his power is some kind of logia that controls the element “wind“. think about it we have only seen him make a tornado in logue town (not sure if spelled right). it would also explain how the lighting was created to save luffy when he was about to be executed, since lightning and thunder are formed by vertical winds rubbing agains eachother creating a electrical field and lighting is produced. so some kind of wind-wind fruit, besides isn’t it wierd that all the main elements have already been introduced. lighting,fire,darkness,magma,ice,light.(of course not water). so only wind is left out.

this is my theory.

Windmill Farms answers:

There’s actually 3 theories of what kind of devil fruit power he might have.

1: As the aforementioned in your post, the Wind logia.

2: A Japanese Dragon that controlled the wind, as a Zoan.

3. ‘Storm’ paramecia.

Renewable Energy Group

Helen asks…

I want to become a Renewable Energy Consultant?

I’m a senior in high school, starting the college application process and I want to become a renewable Energy Consultant. I know by the time I graduate college renewable energy will be the “new thing,”or at least bigger than it is now. I’m wondering what steps I need to go through to actually achieve my goal. thanks. 8)

Windmill Farms answers:

You are on the cusp of dynamically changing world with respect to renewable energy consultant types. I suspect that in 4 to 5 years, much of this world will be relatively specialized with respect to specific energy sources (i.e. Wind, solar, biomass, etc…). Specialized or not, I;m guessing that the consultant world with respect to energy systems will be divided into two groups: the scientific/technical and then the planner/project manager groups.

The scientific/technical types are going to need a math and science background and probably some type of an engineering or physics degree. The planner/project manager types are going to need some business, city planning, and systems management/anaylsis types of courses. Still, if you’re from the technical side of the house, it would help to be able to smooze and speak with the folks funding, politicing, and managing the projects you’re working on. And if you’re from the planning/managing side of the house it would help if you had at least some type of idea what you’re talking about from a technical stand point.

You speak of being a senior. What are you doing this summer? If you already have a bit of physics under your belt, how about starting in on some stats, taking a speech course, or brushing up on some chemistry? The first year of college is pretty much spent taking a series of undergraduate requirements. The function of the undergraduate requirements is to ensure that students are working at par when they start their major’s courses, give them a sampling of subjects they haven’t particularly been exposed to before, and give them a little bit of a general education so that they can funciton in the real world outside of their little group of departmental geeks. Your goal this next year should be to get a firm understanding of a well rounded set of courses; these will form the foundation for the rest of your college career which you either learn now or struggle with the rest of your time. (It’s sort of like learning fractions. Some of us learn and understand them from the onset; others of us struggle and then learn to understand them somewhere between college chemistry and the end of our calculus series.)

Meanwhile, start with your high school and college advisors, high school and college instructors to try to figure out what course work could or should comprise a “Renewable Energy Consultant Degree” . But, be sure to troll the internet to see what other institutions are offering in their assorted green, environmental, alternative energy, and other programs; don’t forget to try to read the course descriptions for skills/things taught and the names of the required textbooks. Troll the internet to see what empolyers are seeking in terms of knowledge and skills for those being hired to perform renewable energy consultation. Ultimately you will learn what you should possess in terms of knowledge and skills despite the name of your degree. And, you may find that there is an institution out there teaching the course work that fits your vision and understanding of what a renewable energy consultant is.

Sandy asks…

environmentalists group?

is there a group or organization i can join for people who are interested in saving the environment. You know, like animal lover have PETA.

Windmill Farms answers:

I recommend Renewable energy Access.

I am a member of this group.

This is a mainstream group, not a crazy left wing group that will scare the daylights out of the mainstream Democrats and make them vote Republican.

That is how George Bush managed to get himself elected in the first place.

Frightened mainstream Democrats voted Republican.

We do not need any more Presidents like George Bush.

What ever you do, do not join a crazy left wing group that frightens mainstream Democrats.

We finally have a chance to have a Democratic President, a Democratic House and a Democratic Senate. This will give us a chance to get some decent legislation passed.

We do not want to blow it.

Mark asks…

renewable and nonrenewable energy?

i need allot of info about renewable and nonrenewable energy
coz im a bit behind in my science class so please i really need info
thanks heaps :)

Windmill Farms answers:

It comes in different forms — heat (thermal), light (radiant), mechanical, electrical, chemical, and nuclear energy. Energy is in everything. We use energy to do everything we do, from making a jump shot to baking our favorite cookies to sending astronauts into space — energy is there, making sure we have the power to do it all. There are two types of energy — stored (potential) energy and working (kinetic) energy. For example, the food you eat contains chemical energy, and your body stores this energy until you release it when you work or play. Learn more about these different forms of energy.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups — renewable (an energy source that can be replenished in a short period of time) and nonrenewable (an energy source that we are using up and cannot recreate in a short period of time). Renewable and nonrenewable energy sources can be used to produce secondary energy sources including electricity and hydrogen.

Renewable energy sources include solar energy, which comes from the sun and can be turned into electricity and heat. Wind, geothermal energy from inside the earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels — oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains (or “fossils”) of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

We use all these energy sources to generate the electricity we need for our homes, businesses, schools, and factories. Electricity “energizes” our computers, lights, refrigerators, washing machines, and air conditioners, to name only a few uses.

We use energy to run our cars and trucks. Both the gasoline used in our cars, and the diesel fuel used in our trucks are made from oil. The propane that fuels our outdoor grills and makes hot air balloons soar is made from oil and natural gas.

Mandy asks…

How come U.S. Lawmakers oppose renewable energy grants?

Windmill Farms answers:

Hey Josh, Reading is exactly right about one point, the oil companies are probably one of the top three groups donating to election coffers. There is more to the point though. First, not all laymakers are opposed to it. If that were true, there wouldn’t be any grants. We actually live in a home that is powered by the wind and sun, and part of it was paid for by a grant over 10 years ago. Grant money for these things has actually increased since then. But you never hear much about it in the news, only the windy ones get their names in the limelight. I personally think the reason you hear so much negative comment from some politicians about renewable energy grants is because the practice has evolved so far and wide, that for whatever reason, the few that do oppose it are making all the noise.

There is also the fact that in many states, oil has become the large, accepted economy there. Take Houston, it would be hard for someone from there to be elected to office without making statements like that, so in the end, they might say what is necessary to get into office rather than what they might really think. We went through all this about 20 years ago with tabacco. We still have places like Winston-Salem, but they are fewer and farther between than places like Houston. Many of our politicians grew up during the big oil boon days of the 70′s and 80′s too. Asking them to help out with renewable energy research and developement is like asking a child of the great depression to help find ways to increase consumer spending to help the economy. Even if you have a good argument, there is no point in making it there.

It sounds like you’re into renewable energy by the way your question is worded. I’ll include some websites below if you’re interested in learning more, and you might find some grant info there as well. Take care Josh, Rudydoo

David asks…

all about biomass energy? I need to know for a project?

I am currently making a poster about renewable energy in my area, and the three I’ve chosen are biomass, solar and wind.

Please give me some pros about using Biomass energy and how it can be obtained. Thanks!

Windmill Farms answers:

It almost sounds as if you are not comfortabe with the term biomass/biomass energy. The “bio” portion of the word comes from biology. The “mass” portion refers to any object with mass or dimention. More often than not, biomass energy is used in conjunction with energy derived from living or dead vegetation from small plants to huge trees. In times past, fecal methane energy (poop power, or what causes the powerful smell of fecal matter) was certainly considered and discussed when biomass energy was mentioned; I’ve listed a couple of Wikipedia pages that better explain just what biomass energy is and is not. Also, a site that is sort of a clearing house and reporting group of biomass projects about the US. You will find additional links on each page/site. (By the way, entering fecal methane energy into the search engine gives a couple of good references too.)

If you’re speaking of chopping down trees and burning them in a fireplace, folks have been doing that for hundreds of years. It is often not considered the best “green” solution to household heating. For as many folks that have chopped or sawed down 60′-200′ trees for firewood through the history of all mankind, far more have gleaned an assortment of biomass materials for heating and cooking purposes. Dried animal dung/scat/poop has been gathered and burned on almost every continent of the world; it is still a routine practice in many areas of the world. Just as many people have gathered and burned fallen branches, dead trees, shrubs, and grasses for the purpose of cooking and heating. All of these fit the biomass energy definition.

Most of the gleaned items we’ve burned as fuel over the time of mankind have been waste or discarded products from some other element of our environment and ecosystem. I will guess that you are not living a nomadic life across the grass plains of the US where buffalo chips are littered across the ground. Rather, your environment and ecosystem is a some combination of “modern industrial society” and agrarian based food products. There is hardly a town in the industrial world that doesn’t have some type of a deep-fat frier. And, where there is a deep fat frier, there is a frier grease disposal need. Did you know that biodiesel can be made from this otherwise waste product? (Check out the fourth link below.) In fact, it is possible for individuals to convert their own vehicle diesel engines and manufacture their own biodiesel in the garage from frier fat?

Just what other biomass based products are readily available in your community, I don’t know. But, it seems as if most of the biomass energy being generated and used in the US today begins with some type of biomass that is the waste stream or by-product of another process, manufacturing plant, or agricultural production. The advantage of this type of biomass energy production is that it more completely or fully uses the materials and by-products of an existing process rather than discarding them unused.

Now, if you include fecal methane energy…where ever there are people or animals gathered, there is opportunity. Again, what the use of fecal methane energy does is more completely and fully use the waste or by-products of other processes. – In this case, it would be good to conjure up the concept of more completely and fully using the elsewise, underutilized, by-product energy of the process of fueling human or animal life.

One of the issues clouding the definition and the use of the term biodiesel is whether to include only plant, vegetation, and vegeartian masses. Or, does one also include things that are in whole or part ominivore or carnivore based?

Is Wind Power Green Energy

Sandra asks…

What is green energy?


Windmill Farms answers:

Ways to create energy without releasing carbon dioxide (or CO2), such as solar, wind, and hydro power. Not burning fossil fuels, such as coal.

Charles asks…

How does winder energy/power advance science?

Windmill Farms answers:

Wind up toys have fascinated children with basic mechanics for centuries and these children may later become scientists because of their fascination.

Wind power technology is green washing, as it’s not load following, it can only be used for base load power and as it’s performance is based on the presence of suitable wind, you can only expect power 1/6th of the time so alternate power sources are required. Wind turbines are rated at their full capacity so they allow utilities to sell power at higher subsidized rates for wind power even though 5/6 of the power are from conventional sources. Wind turbines are just a way of collecting more profit from natural gas power plants.

Linda asks…


Windmill Farms answers:

What one.
Green power is a subset of renewable energy (Graph 1) and represents those renewable energy resources and technologies that provide the highest environmental benefit. EPA defines green power as electricity produced from solar, wind, geothermal, biogas, biomass, and low-impact small hydroelectric sources. Customers often buy green power for avoided environmental impacts and its greenhouse gas reduction benefits.

Ruth asks…

Green energy folks, why is T bone Pickens saying wind power is crap?

Joseph asks…

Can Wind Energy Be Stored?

I’m doing a project where I have to design a “Green” Cruise Ship. I thought it would be cool if my ship ran off of wind energy. I want to create a port where there is a wind farm that my ship would visit every couple weeks….so is it possible to fuel a Cruise Ship with wind like you would gas? Can you store wind power?

Windmill Farms answers:

To store the mechanical energy from wind, different solutions are possible:
- chemical storage (battery or generation of fuels such as hydrogen with the electricity)
- storage as a potential energy (e.g. Generated electricity and use it to pump water in a higher dam so that it can flow again down through turbines and generate again electricity)
- storage as heat or pressure which can be used to run a turbine afterwards
- storage as mechanical energy (e.g. Very fast rotating large steel cyclinder at 100 000 rotations per second… On magnetic bearings)

Uses Of Wind Energy In Rural Areas

Lisa asks…

What are the different types of energy that Australia uses?

Solar, Hydro, Wind, Nuclear… any more?

Windmill Farms answers:

Electricity is generated by coal as well. Australia has large reserves of natural gas and this is used to fuel generators or fuel heating and cooking.

Waste recovery schemes that burn rubbish. Bio-fuels such as bio-diesel are used to run generators in rural areas and both that and ethanol are blended with standard petroleum fuels.

Also simple things like wood pellet or wood waste (offcuts from sawmills) fuel stoves in winter.There are also some combined heat and power systems, where electricity is generated by a factory for its machinery and steam is used via a heat exchanger to heat water for use in those processes or to generate more power which is fed into the grid.

Given the long coastline, wave power is being developed too.

James asks…

Why are wind turbines useful for energy?

Windmill Farms answers:

The U.S. Department of Energy’s (DOE) “Wind Powering America” initiative has set a goal of producing five percent of the nation’s electricity from wind by 2020. DOE projects meant to achieve this goal will provide $60 billion in capital investment to rural America, $1.2 billion in new income to farmers and rural landowners, and 80,000 new jobs during the next 20 years.

Until recently, wind power was concentrated in California. Now it can be found in most states. Farming regions in the Midwest, Great Plains, and West have emerged as major growth areas. Wind power is growing partly as a result of technology improvements and cost reductions and partly in response to state and federal laws and incentives.

While many people will benefit indirectly from the clean air and economic growth brought about by wind power development, farmers can benefit directly. Wind power can provide an important economic boost to farmers. Large wind turbines typically use less than half an acre of land, including access roads, so farmers can continue to plant crops and graze livestock right up to the base of the turbines.

Chris asks…

What are ways Solar energy is used?

I need 5 ways. Thanks in advance!

Windmill Farms answers:

Passive heating – the use of sun rooms or closed cars to allow heat energy in and keep cold air out; dont you love to get in the nice warm car after work on cold frosty fall day? And do not forget the cat like to lay in the sun beam; bag pipes with water in them are exposed to usn to heat water.

Solar electricity: the energy of the sun light is convert inot electrical energy via checmailc interactions.
Satellites use this as well a rural electic fences and some stop signs.

Active sloar heating where sun beam are focused on a samll area to boil water; cook food; even meatl metals.
The heat on certain toys cause the air next tot he toy to heat andthe air under the toy causes it to rise; its fun but not a producer of large amounts of work.

Solar energy is used by plants to convert simple moleucles inot comple carohydrates. These carbs are then harveted and sotred and used by man for food and fuel (wood or yard waste is burnt). Note that peat an scola and oil where once plant life that used soalr energy to create comple carbon chains.

Finally solar energy casue the air around the earth to heat unevenly (lakes; clouds; snow cause unequal heaitng) so the cold air moves in realton to the cold dense air ans we get wind; the wind turns turbines; pushes sails and be get wind power. Also the heat caseu water to evaporate and it htne flots to hihger evelation and when it falls we get flowing rivers whcihare used of trubines: nigagra falls and Hoover Dam just two examples. With out the sun to lift the water it would all have gathered inthe oceans.

Solar power can be used in communications; the shing of sun light off mirros is commonly used in rescuse operations.

So except for nuclear energy, some chemcial reactions; and geo thermal energy and the gratity extended by the moon and sun most energy of earth started out as sun energy.

David asks…

Alternative Energy Programs in the states?

I am graduating high school soon and know what I would like to do with my future. I would like to build solar panels or wind mills or any other form of alternative energy. I love the idea of contributing to a better future that way. Where could I find a program in the states that would give me the qualifications for that?

Windmill Farms answers:

Look for Solar Energy Installers in your area and talk with them. There are certificate programs that you can take as a Solar Installer that only take about 2 years to complete. Check with you state as the electrical codes vary per state.

Solar is growing fast now that the panels are below $1 per watt, when they were above $4 per watt only 4 years ago !!

If you decide to do wind power, expect to work for a utility company as they are the only ones using it, with rare exception of rural farmers.

Finally don’t be fooled into working for a company that leases solar panels to homeowners. They just want to become another form of a utility company. Watch out for them !!!

Richard asks…

Which is the better alternative energy? Solar or wind energy and why?

Windmill Farms answers:

Both have their own advantages. It depends on which area u live.
Solar Panels are a good choice if you live in an area such as a development or there is a lack of wind and wind energy would not be suitable or efficient. But if you are in a more rural area and it seems like the wind blows all the time, then a wind turbine would be an added benefit to help cut your dependency on electricity.

A wind turbine is very similar to solar panels in that it generates electricity that can be used right away or stored for later use. Like solar, wind energy is also a clean fuel that is renewable and doesn’t need any other fuels to function. The electricity generated by wind turbines tends to fluctuate more than with solar because the wind is not as consistent as the sun. So if you do not have a consistent wind source at your location, you can use the wind turbine together with solar panels.

You can visit Mark’s website provided below for more info. He got lot of great information with regards renewable energy. Best of luck to you.

Wind Energy Definition

James asks…

English native speakers! could you help with this? -have energy genarated-?

What happens is, is that any time you have energy generated at all, especially
from a higher plane, a higher dimension, it’s going to come out by spin.
It’s going to be rotation and spin that allows that energy to gate through.
So, by definition, such energy emissions are going to be vortexes.


2. What does AT ALL mean in this sentence? Could you explain in another words?

So it means that in higer dimension, I can’t have energy generated till something swirling emit it?
So, Alter Ego, you mean… AT ALL is like BY ANY MEANS?
principles of being able to bend space using a gravitational pull, it’s very possible that
extraterrestrial craft could somehow get a higher charge of energy from these locations,
like the Bermuda Triangle, which allow them to do a burst of energy, if you will, a warp
speed, and harness some type of extra particles or energies from these locations to get them
where they’re trying to go.

This is the former part of the paragraph. this part is read by Narrator and the paragraph that i questioned is read by a professer.

I totally understood for your help except AT ALL part.

Windmill Farms answers:

By itself, ”YOU HAVE ENERGY GENERATED” doesn’t mean anything. It would have to have a qualifying suffix to the sentence. For instance, ”by means of hydro electric power”.The words ‘at all’ are gratuitous, insofar that the sentence would have the same meaning without them. For instance,” if I am going to go out at all I am bringing my umbrella is the same as;- If I go out I am bringing my umbrella.The term ‘spin’ is confusing and in a sense I feel the author has placed the word there as the ”suggestions” about energy being derived from a higher plane , a higher dimension and ”spin are purposely nebulous and designed to make it difficult to find any meaningful sense ‘. When objects are in a state of spinning they create centrifugal forces,( escaping from the centre), like if you spin a plate with food on it the food will be displaced and ”escape from the centre” and end up on the floor. For spin of centrifugal to occur it normally requires a base energy source. Sorry I can’t be more helpful but the wording of the question and the non scientific description of energy generation would make me dubious of the questionnaire compiler’s own qualifications.ADDITION> To try to help you further may I ask you to expand a little on the context in which the questions are based. I interpret what he is trying to say is,; So, such energy ”sources” (going to power something else) are going to be vortexes. Even that statement isn’t accurate as there has been a ”rotary” engine’ which was developed by the Japanese motor manufacturer,’Mazda’ that powered their vehicle very efficiently. Great heat as in a fire storm will produce a thermal vortex which will have the power to destroy all in it’s path but again there has to be the essential component of a power source to generate the fire vortex. The same applies with a whirlpool or vortex in the sea. Such a phenomenon requires the primary energy source of colliding currents. Cyclones,( a complex system of winds ”rotating” inwards) relies on the energy from hot & cold air currents for it’s creation and duration. “AT ALL” when used in the context of the question is unnecessary and doesn’t add any significance to,nor take away from, it’s meaning. As I have pointed out, if you remove the words ”at all” the sentence still has exactly the same meaning. It does not mean BY ANY MEANS. Please permit me to try to make another example apart from the one I have already given. EXAMPLE;–If I am going to see you ”at all”, it will be on my terms. If I see you it will be on my terms. The question may be trying to infer,;- When you have any amount of energy generated regardless of how little, especially from a higher plane etc. But I still would ask you to accept that you are trying to find a scientific meaning in the needless, superfluous words,”At All” which does not exist.

Richard asks…

Do religious people have a different idea of “energy” than scientists?

Quote: “My definition of soul/spirit: We are made of energy. When we die, we will not cease to exist. Our energy will live on. Energy is neither created nor destroyed.”


I’ve noticed this odd use of the word “energy” to refer to “spirits” and “spiritual energy” repeatedly. But, from the scientific viewpoint, energy is present in a measurable, physical quantity in the universe. Yet, we have religious/spiritual people that seem to use energy in a psuedo-scientific way to refer to a “spiritual” realm which is suppose to be a non-physical realm. Energy is an example of a physical thing, not a non-physical thing.

What is this energy-as-a-spiritual-nonphysical phenomenon about? Do people that claim this even know what they are talking about?
@ Juelann, yes, actually, the sun’s energy can be captured and stored. Plants do it and store the energy in the form of high-energy sugar molecules. It’s the reason that we’re all still alive. Our energy comes from the sun. The energy from the wind is nothing more than kinetic energy from gases. Then you’re getting psychological feelings and projections of the mind mixed up with physical energy.

Windmill Farms answers:

Are the sun’s rays and wind physical things? Can they be captured, contained and measured in the same sense as water or fire? Would any reasonable person dare to claim that the sun or wind has no energy? I think not; on that basis too, simply because we cannot see something tangibly, or measure it with our limited knowledge, –technologically advanced though we believe we are–, nonetheless, energy in the spiritual sense does exist. It does not require belief on anyone’s part to exist or be true.

Have folks experienced unseen energy that can’t be measured–outside of the sun and wind? Oh yes–even the non-spiritual folks (and I say spiritual, as organized spirituality with man-made rules and deemed sacred writings is mere religion, which is a form of control) have experienced this immeasurable energy. There is good, and bad energy. Allow me to explain.

Have you ever walked into a room where there are two or more people who suddenly grow quiet when you enter, and you know by the way they all act towards you, but pointedly avoid one another–through body-language or speech– that there’s been an argument going on right before you entered? As you continue in their presence, you feel strong tension between them– from whence the term “the tension was so thick you could cut the air with a knife” was coined;-does that ring a bell? It is energy that you can feel, but can you measure it? Well, it hasn’t been done, to my knowledge; so the answer would be “no”.

The same goes with good energy; you’re at a party where a lady and gentleman are subtly flirting with one another; they try and keep it normal, interacting with others, but you observe a certain underlying current of attraction between them, even when in their presence, you sense an energy between them; you sense they’re being polite to other party-goers but their real interest is in one another and getting alone. We term that “sexual energy”, right? Can we measure it? Again, not to my knowledge, but we all know that that kind of energy is real, correct?.

By the same token as this kind of energy is valid, and recognized, so too is there spiritual energy, which some folks have been able to tap into; that Great Spirit-Source of Energy (power) is where many of us believe all life forms, and in fact, the entire universe has derived its origin from. Some folks deem all life forms as having a portion of that spiritual energy; others will say only breathing life forms, and yet others will say only humans have this spiritual aspect. Just as not everyone is sensitive to the negative or positive energy that can be felt between people having an argument or who are aroused by one another, so too, there are folks who can connect with their spiritual Energy Source.

However it is to be described–energy, power, life-force, etc., your statement,- -(making it seem a fact, rather than your opinion based on parameters you’ve adhered to),– that “energy is an example of a physical thing, not a non-physical thing” is both inaccurate, as well as an oxymoron (if something is non-physical, it cannot, by definition, be a “thing”). True scientists will all state that –aside from the proven things like gravity, inertia, and the like–most science is the same as religious theology–it’s a premise based on certain assumed “facts” that then evolve into a theory. Let’s be honest here– 40 years ago fingerprinting was the accepted “true identification” standard; now we have DNA, iris matching and a whole world of biometrics. By the same token, 200 yrs ago, blood-letting was considered “the” best scientific method in medicine; we now know differently. 220 years ago, folks believed that thunder & lightening was God speaking, and not a collision of energy in the air (hmm, other nonphysical thing); so, might I suggest that a little bit of room is allowed for us still not having all the answers all neatly wrapped up and bow-tied?

Simply because you and thousands/millions of other people choose to believe one thing, does not make what you believe true. And yes, by the same token, those of us who are believers in spiritualism can also be accused of the same thing–that what we believe (considering it is so diversified) isn’t true just because there are all kinds of different beliefs in spiritual concepts and it can’t be quantified in or by man-made parameters..

Let’s just agree that no one has all the answers and see where it is we can come to agreement on –the need to better interact with everyone and treat all life forms with respect. :-)

Definition of windmill energy in 1-3 sentances?

Windmill Farms answers:

The conversion of kinetic wind energy into electrical energy generated by the movement of the windmills and transferred to the potential energy of battery cells.

Lizzie asks…

Is believing in Free Energy a mental illness?

I know one old man as well as hundreds more on the internet. They think you can find free energy if you just try harder. They spend like 1,000′s on phony books, plans and schemes trying to get free electricity with crackpot inventions. They never stop and no matter what facts/science books you show them they will never believe its fraud. They just say well it was’nt built right. Is this a mental illness? One plan was just copper wire around a plastic cereal bowl and this old man paid for the plans. The other was magnets for a car engine he went on about that for years. It had no fuel….

Windmill Farms answers:

Depends on your definition of “free” energy. In my opinion, wind power, solar power, and hydroelectric power are “free” energy. As long as this planet exists there will be air, water, and solar rays, no shortage problems. All you have to do is make and maintain the harnessing tool for the power. I think any “free” energy plan out there involves having to make something in order to harness this “free” energy. If you’re talking about people that think some type of super-efficient/perpetual motion device is possible, then yeah, they are crazy.

Nancy asks…

What is an example of energy exchange?

I need at least 5 different energy exchanges.
like a car has Mechanical energy from the engine and electromagnetic from the radio. i can’t use that one though
cos it was my teachers example(;

Windmill Farms answers:

(1) Wind turns the propellers of a windmill, generating mechanical energy that is converted into electrical energy sent via high-tension wires to an electric utility plant.

(2) Sunlight shines on a solar panel, which converts the electromagnetic waves of visible light into electrical energy to be used by appliances in a residential home.

(3) Biochemical energy from glucose is used in oxidative phosphorylation to generate ATP (adenosine phosphate), which serves as an energy resource for synthesis of proteins in a cell.

(4) ATP is converted to ADP (adenosine diphosphate), releasing energy that is converted into mechanical energy to be used by the muscles of a athlete (a soccer player or marathon runner).

(5) Electrical energy is used by a high definition television set (HDTV) to convert electromagnetic waves from a geosynchronous satellite into pixelated images and sounds that can be viewed for entertainment or educational use.

Does Wind Power Produce Greenhouse Gases

Ken asks…

How does water heating produce greenhouse gases?

During the process of water heating (gas or electrical) how does it produce greenhouse gases?

Windmill Farms answers:

It is the burning of the fossil fuels, to create the “:heat”,to make the steam, to turn the turbines, to make the electricity, to heat the water, that causes the green house gases, You can avoid greenhouse gases,.if you create the electricity,by using water, wind, solar, or nuclear power to create the electricity,..Gas is pretty clean,..

Mary asks…

explain why energy sources such as wind power,geothermal,tidal and solar power contribute to our energy needs?

explain why energy sources such as wind power,geothermal,tidal and solar power contribute only a small amount to our energy needs

Windmill Farms answers:

Your answer is as follows:

Wind power is gaining popularity and market share, but it requires the wind to blow within a predictable speed range.

Geothermal is currently expensive to produce. Some parts of the world are involved in “Hot Rocks” technology, but it requires deep bore holes to be drilled, and that type of drilling is expensive.

Harnessing tidal energy is still (largely) in the development stage.

Solar power is viewed as only supplemental power due to the fact that (as it is currently done) it cannot generate power twenty-four hours a day.

None of these technologies produce much (if any) greenhouse gas emissions.

Joseph asks…

how does the energy obtained from wind power compare to fossil fuels?

Windmill Farms answers:

It is much less efficient but produces little greenhouse gas and is clean/renewable.

Sandy asks…

Can power from nuclear reactors be used for removing greenhouse gases from the atmosphere?

If a big company builds a nuclear powered gas-conversion plant, to convert atmospheric air with greenhouse gases to cleaner air plus a commercial product such as propane, can they make money that way, or would it cost them too much?

Windmill Farms answers:

It’s possible to use energy to produce hydrogen, and hydrogen to convert CO2. Energy can also be used to condense CO2, deep-well inject it, deep-ocean inject it… So yes energy can be used to do that.
Nuclear power is in fact a very clean source of energy, and one that does not create greenhouse gasses. People are (irrationally) fearful of radioactivity, even though we dig it out of the ground in the first place. And when concentrated, it can be a hazard. But not so bad compared to air pollution, coal mining accidents, black lung… Etc. But the requirements for building a nuclear plant are very stringent, and therefore very expensive. Other energy sources (solar, wind etc.) could also be used. The trick is to have enough surplus power to be able to use it to sequester the greenhouse gasses. Also, the earth itself is responding to help sequester them, as long as the mechanisms aren’t overwhelmed.

Chris asks…

describe the effect these gases could have on the environment?

power stations that burn fossil fuels produce waste gases that can cause pollution describe the effect that these gases could have on the environment and what could be done to reduce the amount of these gases emitted by power stations, in this question you will be assessed on using good english organising information clearly and using specialist terms where appropriate, would really appreciate some help on this i was off during the lessons, not asking for the whole question answered just need some help starting off because I’ve got no idea how to start it

Windmill Farms answers:

All fossil fuel burning power plants produce waste carbon dioxide that once emitted, collects in the troposhere and prevents solar infrared radiation from being reflected off of the Earth and dissipated into space. This is known as the greenhouse effect because the carbon dioxide traps heat like a greenhouse. Scientists believe that the enormous spike in atmospheric carbon dioxide concentrations that has taken place since 1850 (coinciding with the Industrial Revolution) is at least partly responsible for the corresponding increase in average global temperature of 1.8° C. The greenhouse effect has the potential to melt the polar ice caps, raising sea levels far past where they are now (look out United Kingdom!), change native plant species and their ranges, cause extinctions of large numbers of flora and fauna.

An increase in sources of green energy for power will reduce the amount of carbon dioxide being emitted. Wind turbines and solar cells are a couple of examples. Nuclear energy is another source of power that does not cause an increase in carbon dioxide emissions. There are some green energy initiatives in the United States that involve capturing CO2 emissions, liquefying it, and using it in other industries as a solvent. This is becoming common in the production of silicon chips. Also, polystyrene foam can be made using CO2 replacing the ozone destroying CFCs.

Coal burning power plants also emit sulfur dioxide (originating with the naturally occurring sulfur in the coal). Not only does sulfur dioxide and its tropospheric reactions contribute to ground level smog events, but it is the source molecule for the production in the atmosphere of sulfuric acid which constitutes one of the principal components of acid rain.

Acid rain reduces the pH of lakes, rivers, and streams – affecting fish and other wildlife habitats. Acid rain also alters the chemical makeup of soil which can be problematic for farming.

Sulfur dioxide emissions can be reduced by introducing scrubbing mechanisms to the coal burning process or as in the case of CO2, by using alternate and cleaner power sources where possible.

I hope this helps.

Uses Of Wind Energy In Points

Paul asks…

Is Wind Energy widely accepted? Why or Why not? EASY 10 POINTS!?

Windmill Farms answers:

Define “widely accepted”. There are lots of places that use wind energy. But, wind energy has a couple of problems: First is storage. Unless you use the wind to charge a large battery or something like that, the energy is only available when the wind is blowing. Second is infrastructure. Wind turbines take up a lot of space and you need to have them positioned in a place that gets sustained strong winds. Third is environmental concerns, from the noise they make, to the sight of hundreds of windmills on a hillside, to the threat to birds that unknowingly fly into the turbine blades.

However, wind turbines are up and running in some places that you would think they wouldn’t be readily accepted, such as along the hillsides in western Maui in Hawaii. You would think that people living in a pristine tropical paradise would have a problem with windmill farms across their landscape. But, apparently a source of clean, safe power outweighs the other environmental concerns.

John asks…

What is wind energy, what are some positive and Negative points about it?


Windmill Farms answers:

Wind is a form of solar energy created by interactions between atmospheric heating, irregularities in the earth’s surface and the earth’s rotation. Wind is a clean energy source that is endlessly renewable and remarkably reliable. It does not pollute the air or cause acid rain like fossil fuels. (See References 1) Advances in wind turbine technology and an abundance of regions with winds suitable for producing power have made wind power the fastest-growing source of energy in the world. (See References 1, 2)
Zero Greenhouse Gases

Some carbon dioxide is released during manufacture and maintenance of wind turbines, but wind turbines themselves emit no carbon dioxide or other greenhouse gases while they are producing electricity. That means users of wind energy have smaller carbon footprints. (See References 2)
Free Fuel

Building and maintaining wind turbines costs money but no one pays for the wind itself. Since wind is a free fuel, wind power prices do not go through the kind of price fluctuations consumers experience with fossil fuels.(See References 2) Wind power prices in the United States averaged 4 to 6 cents a kilowatt-hour in 2010, making it one of the cheapest renewable energy technologies on the market, according to the U.S. Department of Energy. (See References 1)

The towers and turbines that turn wind into electricity come in different sizes to meet different needs. The biggest wind turbines use rotors spanning more than 100 yards mounted on towers higher than 20-story buildings. One of those monsters can generate enough power to support 1,400 homes. A unit designed to make electricity for a single house might have blades with a diameter as small as 8 feet atop a 30-foot tower. (See References 3)

Wind turbines have to be installed on towers higher than nearby trees and buildings to make the most efficient use of the wind. That high profile sometimes leads to complaints that they detract from the aesthetic appearance of a skyline or a neighborhood. (See References 2) Their blades can also churn out noise that irritates neighbors. “We’re 2,400 feet away and it’s really unbearable. It shakes the house and goes through our bones and bodies,” David Wylie, who lives near three wind turbines in Maine, told the “Portland Press Herald.” (See References 4)
Killer Blades

Wind turbines blades batter birds, killing 20,000 to 37,000 a year in the U.S., according to a 2007 National Academy of Sciences study, “Environmental Impacts of Wind-Energy Projects.” In contrast, at least 90 million birds die annually by flying into buildings, more than 130 million die in collisions with power lines, and millions more are killed by pesticides and domestic cats, according to the study.

Laura asks…

what problem exists when you use either solar or wind energy to generate electrical energy?

Windmill Farms answers:

Both solar and Wind energy are good from pollution point of view. But technical point the intermittent nature of these sources make it at the best an additional source of energy. If you have noticed the wind mill you will see that it does not turn all the time. Wind does not blow at constant speed all the time. So also the sun’s energy. No power gets generated in the night, during rainfall, on cloudy day etc.
Cost for solar panels are high now but it will come down. Wind mills are not so expensive at the moment.

George asks…


Im doing my GCSE’s and heres a science question that I need help with:
Draw a flowchart to show all the enrgy transfers in a wind-up torch starting with food.Show how energy is wasted at each stage.

Thanx for your time! :)

Windmill Farms answers:

Well food gives us energy to do lots of things and we can use this energy to wind up the torch. By moving it we are using up our energy and making kinetic energy which gives the torch energy to use. This energy is then turned into heat light and sound. Light because its a torch, heat because when there is light there is heat, and sound occurs when winding up the torch and energy is wasted/lost when we wind it up and when the energy moves it has to go through certain barriers which use up energy to the actual energy going to the light of the torch is very little compared to what we started with. Hope this helps

Carol asks…

Wind Energy Calculation?

A wind turbine is installed with a blade length of 50m in a location that has average wind velocity of 5.5 miles per hour. Assume density of air is 1.225 kg/m3, the efficiency of the turbine is equal to 20%. (1 mile = 1600m; 1 hr = 3600)

a) What is the power output of this turbine in KW?

b) If the velocity of the wind increased to 7.5 miles per hour, what is the overall increase in power if all other variables remain constant?

Windmill Farms answers:

Hey K, Michaels point of the Optimum turbine is correct, but I’m guessing that this is a theroetical question about turbines in general. There are turbines built for very low wind speed, the Europeans used to make one with a single blade, very long and slender, with a bowling ball shaped counterweight on the opposite side of the hub. The idea is that as you add more blades to a turbine, you lose efficiency, but gain stability in high winds. Well if you want to make power in a 5.5 mph wind, stability is not of any concern, but efficiency is.

The American Wind Energy Association’s website has a great discussion of power in a swept area of a turbine, as well as what a turbine can be expected to generate based on the turbines efficiency. Since you know your turbines size (50M blade radius) and efficiency (20%) you can easily work the formula to get the answers you need. The link below will take you straight to the formula page, but read the entire page first before doing any calculations. Probably the one thing the problem wants you to take away with you is the fact that the power available in the wind increases with the cube of the wind speed. What that means is if you double the wind speed, you get 8 times the energy. You’ll see a dramatic increase in power available from 5.5 to 7.5 mph because of this. Good luck K, and take care, Rudydoo

Micro Wind Turbine

Sandy asks…

What’s the most efficient method of micro- electricity generation?

For example, would I be better placing a solar panel in my roof, or a windmill in my garden? (SCOTLAND)

Windmill Farms answers:

Most efficient or most economical?

Wind is from thermal gradients in the atmosphere because different areas are warmed to a different extent by the sun. In this respect it’s a terribly inefficient method of converting sunlight energy to electrical energy (much less than a fraction of 1%) but a wind turbine is inexpensive.

Solar photovoltaic used to have efficiencies of 5% to 15% but the current record is 42.8%. However, solar panels are expensive.

Currently, wind turbines are less expensive per watt then solar photovoltaics (photovoltaics are dropping in price fast). The problem is that your neighbourhood may not allow wind turbines due to the visual impact and the noise that they create.

Sharon asks…

What are wind eddies?

How are the dimples of a golf ball related to eddies? How can you control and manage eddies?

Windmill Farms answers:

Wind eddies are small vortices that spin in circles in the atmosphere. Because wind (air) is a fluid like water, is moves around objects and impacts the air around it.

If you have ever seen an paddle move through water and watched the little “water tornado” looking things that spin off the sides of the paddle as it moves through the water, these are eddies.

The air does the same exact thing when it blows into buildings, terrain, or other objects. It is just more difficult to see because air can not be seen, unlike water.

As far as how the golf ball dimples relate to eddies, I am not sure. If I were to make a guess, I would image that it is for the eddies (that form off of trees or nearby buildings) would spin the ball rather than move it…but I find it doubtful that the dimples would have even that much of an effect.

It is difficult to control or manage eddies because of the nature of fluid dynamics. I took a course in college called dynamical meteorology where we studied the mathematical equations that describe the fluid atmosphere and how they are used for forecasting. And an eddy is essentially whenever these equations “break” or do not hold true. Much like the waves on a beach are easy to describe with mathematics until the wave breaks, “tumbles over itself” and crashes as it move onto the shore.

Because of this, and because eddies are on such a micro-scale size when considering the size of the atmosphere it is difficult to understand and harness the power of eddies.

However, research is being conducted on “eddy windmills” (this isn’t the name for them, but I forget what they are called) that essentially place a specifically designed object in the wind that causes and semi-continuous eddy and then place this specific type of windmill in the eddy. But at this point that type of technology is merely theoretical. Eddy windmills could also be used for winds that come from any direction.

Below is a link of an “eddy windmill.”

Mark asks…

how does wind energy reach the customer?

As in from windmills/wind farms that capture the wind energy and transform it into electricity… i really really need a source, like a website or article, with it too. thanks!

Windmill Farms answers:

Learning the types of wind farm installation will help you answer your query. These types that can be either offshore or onshore.

Onshore turbine installations in hilly or mountainous regions tend to be on ridgelines generally three kilometers or more inland from the nearest shoreline. This is done to exploit the so-called topographic acceleration as the wind accelerates over a ridge. The additional wind speeds gained in this way make a significant difference to the amount of energy that is produced. Great attention must be paid to the exact positions of the turbines (a process known as micro-siting) because a difference of 30 m can sometimes mean a significant difference in power output. Nearshore turbine installations are on land within three kilometers of a shoreline or on water within ten kilometers of land. These areas are good sites for turbine installation, because of wind produced by convection due to differential heating of land and sea each day. Wind speeds in these zones share the characteristics of both onshore and offshore wind, depending on the prevailing wind direction.

Offshore installation is more expensive than onshore but this depends on the attributes of the site. Offshore towers are generally taller than onshore towers once the submerged height is included. Offshore foundations may be more expensive to build. Power transmission from offshore turbines is through undersea cable, often using high voltage direct current operation if significant distance is to be covered. Offshore saltwater environments also raise maintenance costs by corroding the towers, but fresh-water locations such as the Great Lakes do not. Repairs and maintenance are usually more costly than on onshore turbines. Offshore saltwater wind turbines are outfitted with extensive corrosion protection measures like coatings and cathodic protection, which may not be required in fresh water locations.

To make a community more environmentally sustainable you can get a Greenhouse kit so that you can produce your own vegetables. Producing your own vegetables is far better environmentally than buying them. The vegetables are shipped to the store which uses fuel as well as plastic, because the vegetables were likely packaged when they were shipped to the store.

Renewable Energy Definition

Lisa asks…

mini project on renewable energy?

i have to make a project on renewable energy….can i have some instructions about that ……………actually i am getting confused

Windmill Farms answers:

Well first you have to decide what about renewable energy you want to do a project on. Take into consideration the guidelines of the project if any. There are many types of energy that are classified into renewable energy:

1) Solar Power
2) Wind Power
3) Geothermal Energy
4) Hydro Energy

Remember that the definition of renewable energy is energy that has an everlasting supply and does not have negative effects on the environment.
You can visit my blog for tons of information on renewable energy and green living, as well as DIY wind and solar power kits for those who would like a hands on experience with renewable energy.

Nancy asks…

Difference between conventional energy and renewable energy?

Thank you!

Windmill Farms answers:

By definition, Non-conventional energy is energy that is renewable and ecologically safe, such as solar, tidal, wind, biomass, hydrogen, fuel cell power, etc.
The energy sources are exposed to use from modern technological advancements; rather than the normal use of conventional fuels as energy sources like gas or oil.

Renwable energy comes from non-ending resources.
Which makes them the same.

But if you are talking about nonconventional oil, thats another story.
Non-conventional oil is oil produced or extracted using techniques other than the traditional oil well method.
This is not renwable energy resource.

Carol asks…

A question about renewable energy sourses?

A: do not pollute the environment.
B: are easily available in any environment.
C: protect the ozone layer.
D: are constantly replenished by nature.

Windmill Farms answers:

Biodiesel is a renewable energy source. This will be used to help answer this question.

It does pollute the environment as does any infernal combustion engine. So A is false, in general.

It is difficult to produce, and get clean enough so that ash and the like does not destroy the engine. So B is false, in general.

It produces waste heat and water vapor, both of which contribute to ozone layer depletion. So C is false, in general.

By definition, a renewable energy source, is renewed (or replenished) by Nature. Biodiesel is derived from recently-living plants. So D is the correct answer.

Sandy asks…

What would happen if we didn’t use renewable energy?

What do scientists fear if people didn’t use renewable energy?

Windmill Farms answers:

By definition, non renewable energy can’t be renewed. It is finite and it will run out. We don’t have an accurate measure of how much fossil fuels we have left or how long that supply will last us. Many scientists believe we have passed the 1/2 way mark and we will see shortages in less than 25 years maybe sooner if we don’t learn to conserve what we have.

Renewable energy isn’t just about saving the environment, although most of them are much cleaner and produce far less pollution than fossil fuels. Renewable energy is also about ensuring our quality of life and for many it’s about energy independence.

I have solar panels which produce most of my electricity, when the city raised our rates by 20% it made little difference on my bill, if I hadn’t installed my solar system it would have been an additional $50 per month.

Windmill Farms answers:

Clean energy – energy whose production doesn’t contribute to pollution or global warming

Renewable energy – energy derived from sources which can be fully replenished indefinitely (for the life of our planet) using environmentally sustainable processes

Why good? – because it provides a sustainable pathway to the future

Wind power – intermittent, highly variable, easily harnessed using high turbines, fully renewable and sustainable, “clean”
Solar power – 50% maximum availability, highly variable, easily harnessed using photovoltaic or thermal collectors, fully renewable and sustainable, “clean”
Bio fuel power – partially renewable but not fully sustainable (may produce net CO2 emissions, may compete with food production), not “clean”

Slogan: For a renewable energy poster, why not “Renewable Energy for a Sustainable World” ?

Vertical Wind Turbine

Donald asks…

shaft used in vertical axis wind turbine?

Windmill Farms answers:

Yes, shafts are used in vertical axis wind turbines.

Mark asks…

Has anyone tried a Vertical Axis Wind Turbine for their home?

I have seen a lot of YouTube videos on how easy these are to make and don’t take up nearly the space needed for a normal “windmill”. Has anyone had experience with these? Do they work as efficiently as the normal designs?

Windmill Farms answers:

My husband use to work on the commercial wind turbines . We also did a lot of research on homeowner grade wind turbines, as we want to take our farm to being totally off grid as we can afford it.

Vertical axis turbines have problems with their braking systems (both the commercial and the homeowner sized ones). Also because of their design, they are usually down too low to take advantage of the most sustained winds.

For homeowner ones, we have not found anything better than the Skystream 3.7. Here’s a link to their website:

My husband liked the Skystreams so much he even thought about becoming a dealer selling them, and installing them for homeowners. (We do not sell them and are not affiliated with the company in any way shape or form)

We did a lot of research, and my husband REALLY understands wind turbines and how they function. Hubby is also a helicopter mechanic, and worked on the Prowlers in the Navy. So a great deal of understanding of how turbines function/work on my husband’s part.

He believes the Skystream to be the best design for homeowners.

I like them, because of their great design, which allows the average homeowner to work on them. A cement pad is poured for the Skystream. When it’s installed, it’s bolted down, but it’s also hinged.

So if the turbine, or the blades have to be worked on, the bolts are undone, and the Skystream is laid on the ground, via the hinge, so you can work on it, on the ground, not on a freaking tall ladder, or boom truck.

It also means if you live in an area which gets really bad storms (hurricanes) you can lay your Skystream down, and protect it from being ripped apart by hurricane force winds. You cannot do that with any other wind turbine system.

James asks…

Is the Vertical axis wind turbine requires more wind velocity than the horizontal axis wind turbine….?

Windmill Farms answers:

In vertical axis wind turbine, the wind strike one blade at the rotation direction of blade at the same time it strikes the other blade(s) in opposite to rotation direction of the particular blade. So it requires more wind speed.

However because of the difference between the surface angle of the blades it rotates.

Windmill Farms answers:

While choosing a turbine make sure about the wind directions,
structural mode should be perfect,
consider the material used should resist to the atmospheric humidity,
proper lubrication for the bearing and additional parts.
Shape of the wing should be circular at the edges for continuous flow of wind if it was a rectangular shape think about the rotation of turbine in reverse wind directions.
So every thing i would say is refer the aerodynamic principles…..
