Wind Energy Facts For Kids

William asks…

Ok. My fellow libs, progs and left leaners! I do in fact have a question of orthodoxy on energy?

Oil is bad. We must kill to get it and keep it in good supply at a good price. Not sustainable either.
Coal. Rape the earth. More pollution, more destruction.
Nuclear: Toxic radiactive waste never decomposes. High risk for disaster. Very unforgiving.
Natural Gas: Fracking. Northeast Ohio never had earthquakes when I grew up there as a kid…
Hydro: All those poor species.
So that leaves wind, and solar. And maybe hydro; people seem split on that. Wind and solar can’t power us even IF we all live in cities. With localized economies. And high speed rail.
So tell me how do I get energ policy straight from my brethren on the Left?

Chris asks…

have you ever seen/see ghosts?

im a freaky kid ill admit it! but im just curious if im as weird as everyone says

Windmill Farms answers:

What we call ghosts reside in margin, and we can’t see into that world unless there is a portal or the veil between worlds is thin..
All dimensions have a different vibration, we are surrounded by dimensions we cannot see, but sometimes we do get a glimpse into their world and sometimes they get a glimpse into our world; also remember our dimension is the only dimension where time is measured…

I recently read about a ghost scream which was recorded in England; a team of paranormal researchers were conducting an investigation into a haunting and 3 or 4 women were together in a room when they were taken by surprise by the appearance of a ghost, so they screamed…
The Ghost also must have been taken by surprise as it also screamed, which was recorded on their equipment..
They had the recording analysed and the result was that the scream was not of human origin; so you see we can spook the spooks just like they spook us…

About 1 km up the road from me is an old manse called St Cecilia, this is in Peterborough, Sth Aust…
This old manse hosts 5 ghosts, and the most prominent is the ghost of one of the old Bishops who lived there in the 1870′s..
A friend of mine is a psychic medium and he has been on a couple of documentaries which concern haunted places in Australia, and he has been filmed there several times…
I walk past St Cecilia’s 4 times a week, mostly at around the 9ish PM mark, but sometimes much later on my fitness walk..
I have personally seen the Bishop 3 times, up on the porch on the far left hand side of the the building…
Every time I walk past the manse all the hairs stick up on the back of my neck and I have that feeling of being watched…
Every-time I have seen the Bishop, he is looking directly at me and it sends a shiver straight up my spine..
He knows my energy and I know his, I just hope he stays where he is, as I honestly believe that there is something a wee bit sinister about him…

I will tell you what happened to me when I first moved into my cottage in the country..
One night I got outta the shower and was drying myself in the lounge room and all of a sudden I was freezing cold; I was as cold as if I were naked and out in a blizzard…
I found my winter sleeping clothes(trackie daks, thermal T-shirt and a wind-cheater) and my thick woolly Pancho and I was still shivering; the temperature in my lounge room was 26C so I should have been quite comfortable in just a pair of shorts; the entity had changed my body temperature…
This happened on 3 separate occasions and I contacted a psychic medium mate of mine and we sent him to the light..
He was an adolescent child who was just having a bit of fun, but that fun could have killed me as it is not healthy to be all rugged up in winter clothing etc when it is in fact really quite warm inside the house….
I still have one entity, and he causes me no dramas at all…
In Light… )O(

Ruth asks…

anyone knnow of any migraine support groups?

I am 22, today.I suffer from migraine headaches EVERYDAY. i have been through all the meds on the market for migraines and fda approved seizure meds and antidepressants,everything you could imagine,i have had nerve blocking injections in the back of my head, botox,ekg’s, you name it. done ct scans,mri,mrvs etc.
i black out often and im in pain all day everyday. not any neurologists have come up with any more ideas on what wrongs with me. most migraine sufferers are older in age. im only 22 i wish i could go to college like normal kids i would have to work full time, i cant handle t my head gets so bad..I have always wanted to work on an airline and travel but the pressure makes me hurt so bad i have to be sedated on planes. i wish i could go out with friends like most 22 year olds.i have nobody to help me financially. i lost my job in january b/c i cant handle getting through the day im in so much pain from head to toe. I have actually tried to commit suicide on more than one occasion b/c everyday i wake up with pain and go to bed in pain. i am at my wits end on what to do. most people who get migraines only get a handful a month. mine are pretty much percocet was cut down from 4 a day to only 2 a day because of my overdosing (trying to kill myself) but 2 percocet a day will help in a total of maybe 1 hr a day and then i take my sleeping medications to knock myself out. i dont know what to do anymore. i have to stick around for my family. there are not a lot of people that can understand what its like to live in this much pain. i wanted to see if anyone knows of any support groups(i live in northern va,not far from wash. d.c) or even maybe somone young i cant talk with. thanks, i know its a lot of writing but i would love any suggeations. thanks!

Focussing in your healing

Spiritual Healing /Reiki healing

Spiritual healing/ reiki to many people conjures up so many images and meanings, for those who do not know what it is all about, all that I would ask is that you approach the subject with an open unprejudiced mind and with a wish to explore and evaluate the evidence carefully and properly. It is hoped with such an attitude truth will prevail and misconceptions from misguided people will be put in their rightful place.

From the outset it must be clearly understood that we live on a planet of causes and effects, every thing seen on this planet has a cause and an effect. We live in and are surrounded by all sorts of effects like wind blowing from the north or a light shining from a star or a leaf growing on a tree or wealth, health,suffering,Happiness,Love,Sound,lightning,Music in fact everything we see, feel, touch, smell, all have causes. Magic is the name simply applied to happenings where no obvious cause can be seen, at least to some of those witnessing it.As you can easily appreciate no effect is without a cause.

We are know witnessing one of the great turnings in our century where old healing practises are re-emerging such as Reiki healing, Colour healing, Seichim, Spiritual healing, Osteopathy, Massage and many others. Some of these are thousands of years old, Spiritual healing/reiki is one of those. It is exactly the same kind of energy used by Jesus in so many of his healings.

Put simply Spiritual Healing/Reiki is the transference of certain energies through a channel which could be a person or an animal or even the planet, the wavelengths of this healing energy are well outside the limits of most scientific equipment but a lot of people can feel this energy .

The energy in my experience has been very uplifting and beautiful which can touch and vastly influence parts of us such as the spirit or soul or our mental selves and our physical selves. It can bring a steadiness and balance and sense of well-being second to none .Its limits as to its use are in the realms of the infinite.

A very simplistic analogy would be to liken it to a massive energy reservoir which can be tapped into by people and animals which act as the conduits of this energy and like wires of electricity some of which are bigger than others and so therefore big wires can transmit more energy than smaller wires. Bearing this point in mind the reader can soon appreciate that going to one spiritual healer , Reiki healer can be vastly different than going to another as it is with so many things whether it be dentists, doctors, policeman or what have you.

Spiritual Healing, Reiki is natural healing energy, which is present in this universe. Spiritual healers and Reiki work in many different ways to some it is the laying on of hands onto a person or animal, to others it can be sent through the power of thought. To be even in the presence of some healers can have a profound and beneficial effect on people and one wishes that there were more people giving off just as beautiful vibrations as these people were this world would truly transform it.

Everyone needs healing, because there is not a single person which on some part of their being does not require healing. I will clarify that point further because some people are so physically orientated they perceive people and their suffering on a basis of you look OK you must be OK.

This perception can be likened to looking at a puddle of water and because it looks all right and then assuming that because the rest of the ocean is made of the same kind of stuff it must be the same, being absolutely oblivious to the rest of the entire ocean.

We are a very complicated beings comprising of many different parts some of which are the mental self, the subconscious, the Physical self and the spiritual self. I will leave it up to the reader to discover the parts of themselves and their true importance to their well beings.
During the healing process as a general rule people should simply relax, all sorts of sensations may be felt typically heat, cold, energy, sometimes even noises from your body.

Who is suitable for healing? All people at all stages of their life especially the terminally ill;Animals even plants seem to respond.
Will one session be enough? Sometimes but probably a series may be the answer.
Will healing cure me? All healing from all sources be it Doctor, drugs, etc comes under the law of Karma.

There are no guarantees that healing from any source may give the effect which the Desiree wishes.

However it has been my experience that even if you do not get the effect you desire, on some part of your being you most very probably will receive some healing, even

Robert asks…

what can i teach about the ocean and the sea? (10 points)!!!?

i have to teach a small class of kids ranging from k-3 about the sea and the ocean.
so far i can talk to them about the difference about the sea/ ocean.
the animals living there
and the main seas and oceans

Do you have additional information?
BTW, why is it that only a specific few can live in the sea but not freshwater?
Please help!

Windmill Farms answers:

Here is a lesson plan on how to teach the ocean at K-3 grade levels. Get the materials enough for your small class and use this lesson plan.

Many children hold misconceptions about the nature of water waves. One common misconception is that waves are generated from within the water. Although that may appear to be true, most waves — and certainly the waves most children see are actually generated by wind. As wind travels across the water’s surface, it pushes against the water and energy in the wind is absorbed by the water.

Another common misconception is that as a wave moves the water itself moves with the wave. In fact, a wave is the movement of energy through water. The water moves up and down, but not sideways in the direction of the wave’s motion. The energy from wind moves in the direction of the wind. The energy moves from water molecule to water molecule, making each molecule move in a small circle. When one molecule bangs into its neighboring molecule, energy transfers to that neighboring molecule.

The most effective way to help children replace a misconception is to give them an experience that directly challenges it. In this simple set of activities children use wind to create waves and use marbles to model energy moving through water.


1 large, flat pan, about 4 or 5 inches deep, for each group (dishpans or larger)
1 electric table fan or paper fan for each group
buckets or jugs for filling the pans with water
food dye (optional)
5 large marbles or ball bearings for each group


Ask the class what causes waves. Discuss their ideas.
Put the pans on tables and fill each pan with 2-3 inches of water.
Divide students into as many groups as you have pans and put each group around a pan.
About 1 foot from each pan (on a narrow side), place an electric fan or have a student hold a paper fan facing the pan.
Ask students to predict what will happen when the fan blows across the water’s surface. After students have made predictions, let each fan blow at a low speed.
Have students report the results. Were there waves? Did the water bunch up at the far end of the pan? Did the water slosh out of the pan? Then speed up the fans and have students report again. Make sure students don’t run fans so quickly that water sloshes out of the pans. (It might slosh out with the fan at high speed because the energy in the waves can’t transfer into the pan’s wall readily.)
Discuss with the class the connection between the wind and the waves. Ask students to guess why the water didn’t bunch up at the far end of each pan.

Give each group a set of 5 marbles. Have students place 4 of the marbles on a table, lined up in a row with each marble touching its neighbors. Ask students to predict what will happen if the fifth marble is gently rolled at the marble at one end of the row. After students have made predictions, have one student in each group roll the fifth marble. The marble at the far end of the row will roll away and the others will not move. Have students repeat the experiment several times.
Discuss the idea that the energy in the rolling marble went into the marble it hit, and from that marble to the next, until the energy reached the last marble. The energy made that marble roll away. Wave energy moves through water the same way.

Bring the students together for a wrap-up discussion. Ask them what causes waves. Discuss their answers, relating the answers to the wave experiment. Ask them if water moves sideways inside a wave, or if the water stays in one place while the wave moves through it. Discuss the answers, relating the answers to the wave experiment and to the marble experiment. Goof luck.

Michael asks…

Have you watched the O’Reilly factor recently?

I like Bill O’Reilly usually. He is conservative, but I feel like he tries to be fair. However, have you seen his shows recently? Is it just me, or has he made it his job to tell people why they shouldn’t vote Obama? I just finished watching Tuesdays and Wednesdays shows back to back and he didn’t mention anything about McCain at all. In his talking points he went on about what McCain should be saying to defeat Obama. Why should McCain say it when Bill is saying it for him? He also only had republicans on to back up Bill explaining why he thought Barney Frank should be fired.

I could be wrong. But it seems like ever since Obama retook his lead in the polls, Bill has made it his personal mission to defeat Obama. “Fair and Balanced” got thrown out the window.

Obama’s Economic Plan-Massive Tax increases,massive spending increases,Billions to “help” those overseas as our Economy Crumbles.

Obama’s stand on the Second Amendment-Has one of the most Anti-Second Amendment Voting Records

Maria asks…

Can any one tell me what clean energy is?

and by the way …. plz! let me know:
What are energies’ advantages and disadvantages?
How to use clean energies?
Can clean energies take the place of the current energies?

Windmill Farms answers:

“Clean”, or renewable, energy sources are energy sources that are continuously replenished by natural processes. They are _flows_ of energy (from the Sun or the planet’s hot core) while fossil and nuclear fuels are to great extent _stocks_ of energy (stored, accumulated energy).

According to the World Energy Assessment report (2004) “Renewable energy sources generally depend on energy flows through the Earth’s ecosystem from the insolation of the sun and the geothermal energy of the Earth”.

Broadly, the following are renewable (clean) energy sources:

* Biomass energy (plant growth driven by solar radiation)

* Wind energy (moving air masses driven by solar energy)

* Direct use of solar energy (as for heating and electricity production).

* Hydropower

* Marine energy (such as wave energy, marine current energy, and energy from tidal barrages)

* Geothermal energy (from heat stored in rock by the natural heat flow of the Earth)

If you ask me, if the current reliance on fossil fuels and nuclear can be substituted by use of renewable energy listed above, then my answer would be: “Yes, of course!”. However, to be realistic here, this process will require decades to make such a transition and a lot of political and individual will and commitment.

Wind Power Energy

Donna asks…

Is using wind energy a revolution or just society shaping energy technology?

Will wind energy dominate? Are the people in society pushing for wind energy or is the wind energy technology shaping our society?

Windmill Farms answers:

Using the wind to produce electricity in large quantities is a fairly new concept. Using the wind for power has been around as long as boats first used a sail to move it through the water.
Going Green is right that it will not become dominant because it is unpredictable. The problem with some of the others becoming major sources of power is the same. I live in the northern latitudes, where we get a lot of cloudy weather. We could not depend on solar as our main source of energy. There are a lot of days the wind is not blowing at all, especially in the summer. There are some places trying geothermal, but they have to go down so far to find the necessary heat, that the cost is too high to be practical.
There are no quick and easy solutions to the problem of alternatives to fossil fuels, and there won’t be any time soon.

Helen asks…

What is the percentage of alternative energy sources in your country?

Are alternative power sources (solar energy, wind power, etc) popular in your country?
What is the percentage of their use?

Windmill Farms answers:

On the order of 1% in the U.S. In some states, like California and Texas it is higher, but still less than 5%. I am not counting hydroelectric power in that because it is a traditional source, although totally renewable.

According to the source below, Denmark gets almost 20% of its electricity from wind.

William asks…

What is the price of wind energy electricity?

I would like to compare the price of wind energy, either the cost of one unit of electricity or the cost of a turbine ect. against the rising prices of oil, to see whether wind energy is a sensible investment. All figures have to be accurate, any websites I could find this information on I would be very very grateful for! thanks!

Windmill Farms answers:

There’s no easy answer. I think the wholesale cost of wind-generated electricity is around $70/MWh, compared to about $40/MWh for coal-fired electricity (of course this does not take into account the damage done to the environment by the coal-fired power station). BUT, it is very dependent in things like the price of steel, which is always going up and down, and the cost of credit (ditto). Other variables are things like the quality of the wind resource at the particular site and how many conditions the wind farm has to take into account before it can put the power into the grid. The cost of off-shore wind turbines is about twice that of on-shore; etc. Etc.

Sandy asks…

How does renewable energy help our future?

Anything that can be used to make heat or electricity without unsustainable fuels and which does not make a net contribution of carbon dioxide to the atmosphere. This includes wind power, waves and the tides, solar energy, geothermal energy and biomass. Nuclear power, although it is low-carbon, cannot be counted as a renewable source of energy because its fuel, uranium, is finite.
How does all of that help our future? Thank you.

Windmill Farms answers:

As the name suggest, it is renewable. It means that it can be used again and again but it will not last like coal and petroleum. For example, excess use of solar energy, wind energy will not reduce their stock and is always available forever.

Micro Wind Turbine

Ken asks…

where are the applications of induction generators?

Windmill Farms answers:

An induction generator is a type of electrical generator that is mechanically and electrically similar to a polyphase induction motor. Induction generators produce electrical power when their shaft is rotated faster than the synchronous frequency of the equivalent induction motor. Induction generators are often used in wind turbines and some micro hydro installations due to their ability to produce useful power at varying rotor speeds. Induction generators are mechanically and electrically simpler than other generator types. They are also more rugged, requiring no brushes or commutators.

how to design an experiment?

For my Physics assignment,i want to design a experiment about either wind or solar power .It’s my first time to design an experiment by myself.I have no idea.For wind power,i think i can use a fan as a resource,but i have no idea how to design the next steps.

help me,plz!

Windmill Farms answers:

OK.For Wind power…you need a vacuum ‘blower’- most cylindrical vac cleaners allow you to connect them in reverse. You also need a variac- a mains device to control the current (power output) of your wind source. To measure the power generated by the blower you need a small dc motor connected to a micro/milli ammeter or sophisticated data logging device connected via say a usb interface to your PC with suitable data capture/handling software. Connect a ‘propellor’ to the spindle of your motor. (this can be cut from thin plastic to a variety of desired profiles). Now the difficult have to calibrate the pressure of the air from the blower against known variac this by connecting the blower to a mercury manometer (or bourdon gauge) and measure the overpressure in mmHg/kN/m^2 (this is nearly proportional to the air speed)..nearly done!..Now expt1..vary the wind pressure and measure your current on the ammeter or computer..plot a graph of wind pressure (velocity) against power(current output from motor). Expt2 (qualitative!)..keeping wind pressure constant.. Try different shapes of plastic propellors or turbines to find the most efficient shape. Use a bar graph for these results. Finally(!) write a conclusion based on the mathematical relationship between wind velocity and power output, mentioning that in a scaled up prototype, variation in wind speed and direction would cause the results to deviate from optimum and also state which propellor/turbine/vane is the most efficient design. Good luck!

George asks…

manuals on how to make your own green power?

i would like to know how to make green power with solar power and generator and a battery banks

Windmill Farms answers:

The web-site below is a great place to start. Solar is good in most places, but even better at Southern lattitudes. Wind turbines are good if you’re in a windy enough place. SOME people are even able to take advantage of micro-hydroelectric.

If you live in an area with ‘grid’ power, you might consider setting up a grid-intertied system. You basically use the power grid as your backup battery system. If you produce more electricity than you use, the electric company will send you a check. (If you’ve installed your system without “going guerilla” and doing it illegally.)

The components you’ll likely need include:
1. Power producing hardware (i.e. Solar panels, wind turbines, etc.)
2. An inverter (to convert 12VDC/24VDC power to 120VAC if you intend to run standard appliances an inverter is NOT necessary IF you decide to run on 12VDC/24VDC, but this requires special appliances.)
3. Storage system (batteries, backup generator, and/or tied to regular power system)
4. Support system components and installation (i.e. Mounts for solar panels, poles for wind turbines, outdoor or very vented storage area for batteries, etc.)

Keep in mind if you’re simply looking to save money, making everything as efficeint as possible will pay off the most. Install a programmable thermostat for heating and cooling, use compact flourescents and/or LED’s instead of incandescent bulbs, and energy efficeint appliances normally pay for themselves within a few years.

You can also produce your own fuel, which I’ve heard isn’t THAT hard. Biodiesel may be made from any vegtable oil, and ethanol may be made from certain farm products.

Vertical Wind Power

Robert asks…

Why are wind turbines built with blades stationed vertically?

Wind turbines are built like a clock, with the blades stationed vertically. However, this seems to limit it – the blades only spin when wind is blowing in two directions.
However, if the blades were placed horizontally, spinning like a merry-go-round, it seems like it would be much more effective. If constructed in this manner, wind could blow in all directions and move the blades.

Windmill Farms answers:

Hey Michael, Ben is correct about the vertical type turbines. The reason none of the power companies use them, is because they are horribly inefficient. Most of the energy absorbed by the downwind blade is used forcine the upwind blade back into position for the next cycle, and very little is left to produce power. Typically, this type of wind turbine, called a Darrieus Rotor, is about 5 to 8 % efficient, meaning less than 1/15th of the winds power is converted into useable torque, or electricity, and the rest is just wasted churning the blade around in the wind. Horizontal units, and in particular the 2 or 3 blade units generally operate at about 30 to 35 % efficiency, or about 6 times more efficient than a comperably sized Darrieus Rotor. The smaller home sized units like ours have a tail that constantly turns the unit to face the wind regardless of where it is coming from. Older farm type turbines with 12 or 15 blades on them usually worked this way too. That type of turbine, with the multitude of wide flat blades were almost never used for electrcity generation, they were also not very efficient. In most cases, they were used to pump water, and in that way what was needed more than efficiency was low wind start up torque. The large multiple blades worked better for this, but tended to stall out in higher winds. Electrical generating wind turbines work much better in high winds and at high RPM’s, so fewer blades is ideal for this.

The really large utility sized turbines you see that have no tail are either fixed to face one direction where the wind is almost always blowing from, like along the coast, or they have a small anemometer on top that senses the winds direction, and a computer uses a small gear motor to physically turn the unit to face the wind if necessary. These are typical in the midwest. Darrieus Rotors, and their close cousin, the Savonius Rotor, are really neat looking devices, and they are great for small garden pond pumps or outdoor garden lighting, but they are ill equipped to produce enough power to run even a household refrigerator. There is a great article at the American Wind Energy Associations website written by Mick Sagrillo about this, if you want to learn more, check it out. Mick is considered by many in the renewable energy world to be the modern day guru on wind power. Take care Micheal, Rudydoo

Susan asks…

There are wind turbines that are vertical axis orientation but never aren to be working ?

Is this a design that could withstand recent Typhoon Haiyan ?

Windmill Farms answers:

Hey B, vertical axis turbines are no less susceptible to damage from high winds than horizontal. The reason for this is pretty simple. Most turbines, regardless of orientation, have a specified survival speed, frequently 100 mph or more. This is what the turbine is designed to deal with while it is running. It may not be producing power, as many actually turn away from the wind or have braking systems that slow them down in really high winds. Once you stop the rotor from turning, they can actually withstand more wind than specifications, but in almost all cases with winds in excess of 100mph, what damages the turbine is not the wind, it’s the debris. You can design the best turbine and tower in the world, and it won’t withstand a cow travelling through the air at 100mph, so it makes no difference which way the shaft runs.

As an engineering note, vertical axis turbines, or “Darrieus Rotors,” are notoriously inefficient, generally converting about 8% of the winds power to usable torque, this is the reason all the really big turbines the power companies use today are horizontal axis, they make more power for the dollar. Vertical axis turbines are “really neat,” but then so is the Tesla Roadster, and I don’t know anyone personally who owns one of those either. We have a turbine at our home, it’s small, about the size of a large ceiling fan, but on a windy night it can just power the entire home. It has a horizontal axis. Take care, Rudydoo

Ken asks…

Wind turbine project ideas?

I have to make a wind turbine for an engineering project. It has to lift stacks of coins in 50 coin intervals. 50 coins the first time, 100 the second time, 150 the third time, and so on. It Has to lift the load .5 meters above the ground or platform that it is on. The wind for the power will be generated by two Industrial fans.

There is a catch to this though. The entire project must be made from things that are found around the house. We can not use materials that have been purchased.

I have a few ideas but i just wanted to see if anyone else had any.

Much Thanks.
Thanks for all the help so far. But im looking for some more ideas on how to use this to actually lift the coins. Any ideas with that?

Windmill Farms answers:

You can make various types of homemade turbines. A vertical axis wind turbine is easier to make but less efficient then a horizontal axis turbine. Also since you have to lift load off the ground vertically, my advice is to use a horizontal axis turbine (the one that looks like a fan). U can easily make the blades from wood or even PVC pipes.


for wood u can carve out a shape of a turbine blade in it. Use a piece of timber, chip with a chisel and then polish to smoothness using sandpaper or a file.

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…)
We literally live right on/next to the beach, so we always have plenty of wind currents!
It is not possible to purchase any other type of wind turbine, as we do not have enough room for huge turbines. We were considering attaching them atop light posts and using them to power these huge “cutters” that shred “things” from out toilets, sinks, etc before leaving to a sewage plant. These “cutters” use a tremendous amount of energy and cost the town $20,000-$25,000 in electrical energy alone.

Windmill Farms answers:

Hey Love Me…I’m curious what got you interested in that particular type of wind turbine? The vertical helix used to be called the Darrieus Rotor, named after a French engineer who invented it years ago. They were never meant for power developement because they are fairly inefficient as wind turbines go, and since all the stress of the wind load has to act on the base of the rotor, until recently, you never saw them in any real size. For the swept area they cover, lots of the energy is used up swinging the rotor the wrong way through its circular course, but it still acts as a side load even on the trip back to its power curve portion of its rotation. They were used as small water pumpers for remote locations, or to power a small DC generator for remote electronics, like an unmanned weather station. To take one of these devices and use it to make thousands of kilowatts of power would be kin to using minivans to haul jersey barriers around town. There are naturally people in a hurry to sell something like this because the world is suddenly in the market for all things renewable, and they look really neat, but there is a reason that nearly all wind turbines designed to produce electricity over the last 50 or 100 years are horizontal axis. In a horizontal axis turbine, the blade is producing power during its entire rotation, and can produce much more power in the same swept area as the Darrieus Rotor, yet all the side load forces act at the hub which is very near the center of pressure of the rotating blades.

The most efficient wind turbine in the world will never operate above an efficiency of 39%. This is referred to as the Betz Limit, again named after an engineer who developed it some 60 years ago or so, most horizontal axis commercially built units today operate in the 25 to 30 % range, pretty good as wind turbines go. My suggestion, since you are involved in more than buying one of these to put in your garden, is not to waste your time asking hacks like me online for advice, go to the source where people work with these things all the time. The American Wind Energy Association has been testing, promoting and improving designs for years, and they run classes on these things. There are some other places to look for info as well, I will list them below.

In case you’re wondering, the reason we know all this is we live in a home that is powered by the wind and sun, has been for over 10 years now. I can assure you that we haven’t saved any real money making our own energy, for us it has become more of a hobby and environmental cause. Utility power in most places today is really inexpensive when you consider all that goes into making and shipping it. Some people grow their own tomatoes even though they are cheaper to buy at the store. In addition to the cost and time invested, they have to know about watering, ph, bugs and dirt. People that grow their own electrons have a similar curse, we have to know where each one goes in our house, because we would rather eat a bug than start up the generator. Check out the sources below, and try to make it to one of the energy fairs listed in Home Power Magazine, that is where we got started. In the end, you might decide not to get involved at all, and that’s fine, but at least you will be well informed. Good luck, and take care, Rudydoo

Daniel asks…

Building a vertical wind powered generator.?

I am fortunate to have two treadmill motors. First one is a 3HP, 115.5 volts DC, 21 Amps and 2238 watts. The other is 2.5HP, 130 volts DC, 16.6 Amps and no watt rating on the data label. My question is: What kind of power am I looking to create once I have the generator in the a 10 mph wind. I plan to connect it to a stand alone workshop. It will not be tied to the grid. I also plan on a battery back up to store power. Thanks for your assistance. Mike

Windmill Farms answers:

When the motors are operating at their rated speeds, they are probably capable of generating something close to their rated input. That would be 115V, 21A, 2400W for the 3 Hp motor and 130V, 16.6A, 2100W for the 2.5 Hp motor. The voltage will vary with speed. The field winding may need to be reconnected or separately energized.

Is Wind Power Green Pros And Cons

Donald asks…

Pros and cons to living in Washington state?

I’m thinking to moving to the west part Washington state after high school from Arizona, before I do so though I want to know some of the pros and cons to living there first.

Windmill Farms answers:

WEll, I live about 30 miles as the crow flies west of Seattle, in the middle of a modest forest where they cleared land for roads and foundations. The trees mostly are all still there. My backyard is forest. In 1968, I enlisted int eh Navy. I went into nuclear power and then into submarines. My first was stationed in Vallejo, CA. 10 days after I reported aboard, we left to go up to Puget Sound. It was August, 1971, and we steamed in through the Straight of Juan de Fuca, and turned south down the Hood Canal. The sun was just about to rise, and as it did, it lit up the Olympic Mountains to the west. All I could see was how GREEN it all was, trees everywhere. I decided then and there I would one day return to live here. I got the chance after 18 years to get stationed here, and I left the Navy after 21 years and just stayed on… All I can say is we seem to live at a slower rate of speed outside of the big cities. People seem to be more polite here overall. At a 4 way stop sign, most everyone will yield the right of way even if it is theirs by law… Western WA is quite different than you would expect for being so far north. Lots of rain, rarely snow. The ocean keeps the area west of the Cascade Mountains cool in summer and warm in winter. East of the Cascades gets several feet of snow in the winter. However, cities are cities and Seattle is not all that different than any other big city where I’ve lived. What IS different is the rural areas outside of the big cities (where I live NOW, for example), where the pace of living is not quite so hectic… At night is gets so quiet that I can hear a ticking clock at the other end of the house from my bedroom. The trees in my front and backyard are about 100 feet tall and densely spaced, so wind is never a problem at ground level. I have no idea if any of this will help you. I’m 64 and retired on a modest pension, so MY take on this green, green place where I live is likely to be quite different from yours…

EDIT: silly, silly ME… THIS is a TROLL… And the opening plotline from Twilight where Bella ends up in Forks, WA… Forks is about 100 miles to the NW of where I live…

Mary asks…

Pros and cons of proportional representation in the UK?


Windmill Farms answers:

1) More representative government – easier for smaller parties (eg: Greens, UKIP) to get MPs
2) Would eliminate “safe” seats like Richmond (Yorks.), Bootle, Orkney & Shetland or Antrim North
3) Would likely increase voter turnout – elections no longer a foregone conclusion
4) Legislation could be properly debated in Parliament without three-figure majorities to force through controversial legislation (eg: ID cards)
5) No more tactical voting – you could vote what you felt to be the best party rather than the least awful
6) EDIT: in the 2005 election Labour got about 36% of the vote and wound up with a majority of about 64. Proportional representation would ensure this never happened again

1) Would make coalitions (or at least minority governments) virtually inevitable, with (most likely) the DUP/Greens/SNP/UKIP holding the balance of power
2) Certain forms (such as Israel’s national list system) break any bond between MPs and their constituency

Personally I’d be in favour of the Single Transferable Vote (as used in Ireland, Malta, Tasmania and Scottish council elections) or possibly an Additional Member system (as used in Germany, New Zealand and the Scottish Parliament).

Ken asks…

your opinion on the use of nuclear power?

Windmill Farms answers:

Should we be using more of it? Yes.

No source of power is without its pros and cons. If the goal of the US is to reduce green house gasses, while still meeting the growing power needs our country then nuclear power is the way to go. Things like solar and wind are great, but they cannot provide more than a small percentage of our power requirements. Sure, we should continue to develop them but right now and for the next 30-50 years, nuclear power should certainly play more of a role in our power strategy.

In my state of California, the majority of our electricity comes from plants burning natural gas. As a side effect of this, the rates for natural gas and electricity in California are the highest in the nation. This is not a sustainable model.

Sandy asks…

What green/sustainable topic should I write about?

I need to write an article for an online site on any green/sustainable/renewable/etc. topic. If you could choose – do you have any ideas as to what you would like to hear about? The audience is the general public, but more specifically the site is geared towards people at least interested in sustainability (in other words, the idea’s could range from a “novice” to “advanced” reader – so all comments are welcome!).

My personal background is in sustainable construction and large scale renewable energy developments. I can explain anything relating to: technical, finance/economics, practicality, etc.

Any ideas? Are there any topics anyone would like clarified or explained? I’m ultimately just wondering what people want to know about! I’d hate to write a boring article! Please provide general or specific comments or questions just to get some ideas started. Thanks!!!

Windmill Farms answers:

If your target audience is in a specific region then explain the various discounts, rebates, and grants that may be available or running out.
A series of articles explaining the nuances of each type of power generation with pros and cons.
Examples would be Solar Power PV vs Thermal. Then PV broken down to Amorphous vs Mono & Poly Crystalline. Wind mills vs power turbines vs vertical axis.

Joseph asks…

Go Green tips anyone?

Hey, I’m working on a website about going green. Would anyone like to write an article on ways to go green? It can be about anything. A Few ideas are:
how to green different rooms of the house
effects of global warming
vegan lifestyles
animal rights awareness

Can you please post your article with your full name please.
The best article will be featured on the home page and the others will all be included on the site too.

Windmill Farms answers:

Going green can be a difficult transition for some people. However, that is only because they don’t truly understand how green they are to begin with. Alot of people are half way green and won’t have a clue until they eventually try to be a green individual. So just how does one green up his or her act?

Lets begin with the biggest piece of the puzzle. You’re home can easily be made greener. You can turn your lights out when you leave the room, or you can flip the circuit breaker to rooms that are used very infrequently. Lower wattage bulbs can also help. Keep in mind your options now include LED and CFL. Each of which has their own pros and cons. Another option is to use the sun for light during the day. No need to waste precious power when the sun is shining for free. Just angle your blinds or open your curtains when you need extra light. A sun roof can aslo be a very good option if you want free day light.

Now when it gets to be summer time your home will definetely get warmer. There are numerous ways to avoid this. You can simply plant big bushy trees on the southwestern side to limit the heat of the evening sun. You can move your bedroom to the eastern most room. This way you can wake up with morning sun and avoid having to go to bed in an oven. Keeping the blinds drawn on the side recieving the most sun can also help.

Another home cooling idea is to open the windows so that air can pass through. If you have a pair of box fans you can create a wind cycle in your home. Taking 1 fan and placing it so that it pulls air in, and using the other across the room or house to pump air out. This will keep the air circulating and prevent stale air from building up. Placing additional fan in formation to keep the air flow unidirectional can help this too. Remember an A/C can only cool a sealed room. A fan can cool any room by keep the air flowing.

Does it just seem like you’re killing yourself cleaning? Well you could be and not even know it. If you take certain cleaners and look at the ingredients you can be shocked at just what you pump into your home. I prefer to use baking soda, vinegar, and castile soap. It’s three reasonably natural and safe cleaners. There are numerous websites that explain how to clean with each one. For instance you can scrub pots and pans with a cloth covered in baking soda and rinse with lemon juice to cut down on tough messes. Keeping in mind that you rinse again with water and soap to finish the job.

Now see how little you had to do to bump your green rating? Anybody can go green, but the key is to continue to find new things and remember the three key rules of green living. Reduce. Reuse. Recycle.

Uses Of Wind Energy In India

Lizzie asks…

alternative energy?

solar, hydro, geothermal, wind, hydrogen fuel cells; what else have i missed?
uhh..interesting, but something feasible and current please?

Windmill Farms answers:

Bio Fuels and Human resources energy. But bio fuel is turning out to be a non-starter. In Bangalore, India, the government transport started using bio fuel in 110 buses and after 6 months trial, they have reverted back to diesel. Reason: bio fuel is costlier than.
Most affluent people in urban areas, go to gym and try to burn up lazily accumulated calories. While they have a right, their energy burning exercises can be converted into electrical energy by simply making them run on static bicycles with one wheel. A dynamo is attached to the wheel and the turning wheel can produce electricity that can be stored in batteries. This method can also provide employment opportunity to the unemployed youth.
Solar energy can be harnessed in different ways. But U-SEE the following World Bank honored innovative initiative, do it at home, make copies of the methodology, circulate it to the community and save the world:
Knowingly or unknowingly we are all partners in misusing of costly electricity for our lighting purpose during day time when the solar light is available just outside our windows. Why can’t bring home the sunshine?
Yes. This has been successfully adopted by a number of people in Bangalore, India. This innovative but simple method of bringing home the sunshine was suggested to the World Bank as a Grassroots Initiative for Preservation of Natural Resourcs during IDM-2007 competition – Project U-SEE (Unlimited Savings of Electrical Energy). U-SEE does not involve any nano technology nor does it requires billions of dollars for implementation. Moreover, U-SEE you get free lighting for life. No charges.
The World Bank honored this initiative and has created a permanent blog on the World Bank URL at
How is it implemented? U need a house hold mirror of 12″X18″ and a pillow. Identify where u can get maximum sunshine just outside the windows with clear glass or on the balcony, keep the pillow on a stool or chair and place the mirror on the pillow, go on nudging the mirror till the solar light is deflected from the mirror, through the window and on to the white ceiling inside your home. U will be surprised to find the light spreading from the ceiling – it can be 40 to 60 watts (see the picture above – notice tube light and table lamp in the corner are not burning but there is enough light). If u can keep a bigger mirror, u will get more bright light. U can control the light just by covering a portion of the mirror.
Earth moves on its latitude. When u find that the deflected solar light is moving elsewhere, just go to the mirror, nudge a little and u can get back your light as before. THIS IS THE BASIC IDEA and once u have done it, u be the Innovator of your light requirements for your home and U-SEE PROVIDES YOU FREE LIGHTING FOR LIFE. Many homes/huts in rural areas in developing countries do not have proper lighting and people are living in dark, damp and dingy environs but urbanites living in concrete jungles in cities with tinted glasses are misusing electricity for their lighting purpose even during day time.
U-SEE the Benefits: ONE incandescent bulb/tubelight burning for 6 hours during day time consumes 7 units of electricity in a month. If half the world can adopt U-SEE and switch off one bulb for 6 hours during day time, how much of electricity can be saved? Your guess is as good as mine + saves cost of fossil fuels, coal, water+saves cost incurred for machineries and equipments+saves overhead charges+saves transmission loss charges+saves the world from global warming (burning bulbs/CO2 etc) with n’th value+ U GET FREE LIGHTING FOR LIFE with n’th value. The savings that accrue can off set the load on our productive requirements like A/c, refrigerators, mixies, fans etc.
Solar light will be available at least for about 200 days in a year and it is infinite and why should we let it go waste? We are not harnessing this infinite energy. U-SEE is ssoo simple.
First adopt this method, innovate solutions if u face small problems. U be the winner. U-SEE It is a win win situation for all of us. Need clarifications, mail: U-SEE – The author’s ambition is to spread this friendly initiative to one and all. No charges!!

Will 123 Agreement be Favour for India’s Future and Feature?


Windmill Farms answers:

There are two opinions….
1)we are now lack of energy–the sudden need for it is the industrial growth,malls and all others…we can get it from solar,water,wind and thermal…..but they are not everyone wants a simpler solution…so there is nuclear energy in which only gms of uranium can give you energy equivalent to tons of coal…now there is only one place in zarkhand where we get this uranium and that is not india will get uranium from other country that will help it to get more energy…

2)But we have to keep some of our nuclear reactors under inspection of US where we cannot do any research..just use uranium for energy that’s it….that is what USA wants….So they wants inspection of of our reactors that we r not planning of any bombs..also after agreement we have to “OBEY” them in some matters…like england has helped USA in iraq war…

Chris asks…

Should India use nuclear power?

Please give explanation for your answers.

Windmill Farms answers:

Yes, it is a better alternative than carbon based fuels. It would greatly reduce pollution, reduce costs, and reduce dependence on foreign nations.
India and the U.S. Will develop better sources of power in the next decade or two. A more efficient and less dangerous nuclear fuel is one possibility along with new forms of renewable energy. Wind power, solar power, hydroelectric, bio-diesel, and coal have specialized uses that should not be ignored but are not nearly total answers to the problem.

What are the top ten nations as far as constructing, subsidizing, researching, serious-planning for: Solar, Wind, Wave, Geothermal, and Renewable energy. [Not including fossil or nuclear energy]

I am looking for a ranking based on either current renewable energy production per capita, and/or projected energy production per capita a decade or two from now.

~ thanks for your answers ~

Windmill Farms answers:

Wind power is growing at the rate of 30% annually, with a worldwide installed capacity of 238,000 megawatts (MW) at the end of 2011, and is widely used in Europe, Asia, and the United States. At the end of 2011 the photovoltaic (PV) capacity worldwide was 67,000 MW, and PV power stations are popular in Germany and Italy. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 megawatt (MW) SEGS power plant in the Mojave Desert. The world’s largest geothermal power installation is the Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugarcane, and ethanol now provides 18% of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.

Here are the Top Ten Nations that have been using Renewable Energy:
China 52,800
United States 42,432
Germany 27,981
Spain 21,150
India 14,550
Italy 6,200
France 6,060

Alternative Energy ? First thought solar panels. How many cheap, handy and flashy forms are there A.Energy?

Alternative sounds odd, weirdy, primitive..How about running a flashy car on cheap spirit? And having a comfortable home heated or cooled naturally by ??

Windmill Farms answers:

Hi Nischal, i’m interested in Alternative Energy. Its not only Solar panels, it can also be wind generators, in India, Solar panels r being used to heat water, but not very efficiently, i’m keen on making small wind generators that will charge car batteries, n when there’s no wind, the batteries will run small appliances like lights n fans, for starters.
About running cars on spirit, first, the process of making spirit should be easy n non-toxic. N second, You need an adequate n constant supply of it to be sure You don’t get stuck when You r away from the spirit refill station.

Let me know if You r interested in doin more research on Alternative n Free Energy, i do have a few sites.

Windmill Farms answers:

Wind energy doesn’t create pollution – as opposed to fossil fuels.

Wind energy is sometimes easier to use than other sources of energy – like sailing ships using their screens to catch wind to accelerate the ship.

Bah, can’t think of any more :p

Donna asks…

Does anyone know of a renewable energy source (other than solar, wind, or water) that returns more energy?

Windmill Farms answers:

You did a great job of identifying the common energy found in the general press. However, you did leave out Biological, Geothermal and Oceanic Energy. Geothermal sources are well documented there are several untapped sources that could add almost 1% to the US energy sources. Others who have responded to you shared Biological sources such as Methane and Ethanol. However, they failed to mention the Methane Hydrates that are in the Caribbean Sea. (This is technically a fossil fuel rather then a renewable.)

When you spoke of water I take it you were thinking hydro-power such as dammed river basins. There are three primary Ocean based sources that I think do not get much play. Thermal, Wave and Tidal are all Ocean water power.

Thermal power makes use of the difference in deep water cooler temperatures and warmer surface temperatures. Using a Rankine or Sterling engine it should be possible to use the cooler water of the deep ocean (between 200 and 400 meters) to return the working fluid to fluid and extract power from the difference in the phase change or fluid expansion. The issue is to achieve this depth requires that the power extraction needs to be fairly far into the ocean and unless the power generated is used to convert water to hydrogen the transfer of the power under water is inefficient.

Wave energy uses two different mediums, one is the difference in air pressure in a cylinder as the waves raise and lower the pressure in the cylinder increases and reduces and act as a kind of low pressure bellows for moving air. Whether this would be enough for producing significant energy remains to be seen. (A new method using a fluid and a valve that takes advantage of both the increase and the decrease of pressure exerted by the changing water levels appears to have some merit.) The other method is a direct mechanical energy conversion where the rising wave front raises a buoy which either pulls up on a crankshaft or a cable and in the trough the cable length or crank returns to minimum.

And finally there is tidal, there are two different types of Tidal or Ocean current extraction. The first is the most common in which a bay or tidal estuary is dammed (barricade) and the difference in heights between the Ocean and the tidal estuary form the head or force applied to a submerged turbine.

The other method is called Tidal Stream. In this method the turbine is submerged in a natural narrowing such as an inlet or in deeper water and take advantage of the flow or currents of water energy. Of the two the Tidal Stream is the least common and is in it’s infancy. As you can place a large quantity of Tidal Stream converters in open Ocean waters it has the greatest opportunity to generate the most energy for the least amount of environmental change.

However, I do have a question for you. In your consideration of Solar energy you probably have explored Photovoltaic Cells and Solar Furnaces; however, have you explored Solar Chimneys? There was an experiment done in the late 70′s in Spain in which a large metal “Chimney” was painted black and as it heated up cooler surface air would enter at the bottom and rise towards the top where a turbine was installed.

Sandy asks…

energy crisis and nuclear power?

what is the solution for energy crisis

Windmill Farms answers:

Solar, wind, and even wave motion capture from the ocean to turn into electricity. Hydrogen costs more to make then using electricity made from solar or wind. We can also use grass fuel like Venezuela is using and this country has levied heavy taxes on their grasses so our oil men can make more money instead–makes no sense, need to change the political air to something we can breathe.

See the special on TV on “Who Killed the Electric Car” that ran recently on cable. We can also use ocean salt water for fuel, see the websites on the research. We can run a whole state if we can put into action the panels that can go up and few miles and capture the solar energy & transmit the energy by microwave. This was also a special on cable, check the various “Planet Green” channels and also the history and science channels.

Nuclear would be good if we could dispose of the horrible spent rods & heavy water safely, but we can’t. The only real way of disposing of nuclear waste is sending it to the sun itself which is a nuclear reaction, but what if the rocket had a problem taking off? That is the issue and burying it, someday it can get into the ground water which would destroy so much.

Best bet is electric power cars, and some can go over 300 miles on one charge that cost about ten cents a mile and this was done 10 years ago and the oil men brought out so many EV1 cars and those that manufacture parts for such ventures.

Why the problem? Until this new Depression, those that made gasoline engines that needed filters, oil, plugs, and so much work–would have made nothing with an electric motor–but now, they are out of work altogether because no one wanted to see the future. Like the lumberjacks, fighting to cut down millions of natural forests to keep their jobs, but what happens when all the trees are gone? Some say plant bamboo forests, but there are only certain kinds that can make decent wood, and there are areas where they can’t grow. Some of them are like weeds and not profitable.

We need more hemp or grass fuel for oil, cloth, paper and insulation too. There are a lot of alternatives out there, but we need more people working on making it better. They recently came up with paper thin solar panels that can be used as siding and roof shingles, so there is hope yet we can make a home self-sufficient. See the various TV shows on environmental issues, they are always bringing in new technology in hopes of getting more people interested in investing. Even on Yahoo tech websites they show new ways of using alternative power for homes, cities and autos.

Windmill Farms answers:

If u say obama FORCE people to use wind and solar then yes

jobs will go to China, because wind and solar technologies so far are not mainstream nor mass produced so they are very very expensive. If we get China to manufacture solar panels and wind turbines, then these sources of energy will become much more affordable and benefit the world

Laura asks…

who here is in the solar energy, PV, field and lives in the US?

Im interested in talking about the solar energy PV market in the US.
I am looking for manufacturers, site planners, retailer, etc.
heres the question;
In what year will US citizens invest in solar modules as a source of income? what year will the cost of the modules become affordable and profitable?

Windmill Farms answers:

A Photovoltaic Installation & System designer which provide solar /wind energy consulting service to residential, businesses, city, or foreign governments on how to develop solar electric system sizing !

Here I may be of help to address what we have found within the market place particularly to state a few examples:
A Trillion Dollar Market Opportunity
That Which Can Create JOBS

1.ZEH zero-energy homes new development for investors
2.Commericial application for cost reduction shopping mall ,etc. governments create resolutions of 10% goal of solar /renewable energy for it citizens
4.educated against the fear or myth on how & why the solar /wind /bio-fuel help hedge against inflationary effect of rising energy cost.

Now to address your question on what year will US citizens invest in solar modules as a source of income? What year will the cost of the modules become affordable and profitable?

Our predictions will relate to the an historic earmark price of gas prices climbing between 3.75 to 4.35 per gallon in terms per barrel anything between 75 to 95 dollars or euro.

Why the impact out reach every facets of the USA economy mean many will be force to reside or spend more time at home and travel for goods, products , and service will be effected to the point of increases in cost but the true indicator will be the electric &heating bills !

If a homeowners owes a note of 750 to 2000 per month the electric rates across the country will rise between 70% to 150% to the average homeowner its can mean for example :

Home & Auto Energy Crisis
.a. Monthly utilities bill averaging 200 the rate increase could mean paying 400

b. Average electric or heating bill if its 400 the rate increase can mean 800 and its can mean for business serious decisions on employees or the cost on product items to the consumer1

We can call these invisible forces impacting upon top of rising insurance cost & food!
We can label this the FUEL & FOOD Crisis!

So the prediction is increase effect of the rising energy cost will directly force the consumer market to search for alternative energy solutions immediate whereby this will be a stimulus within the job market & for investors!

And the last question ties directly in proportion to the consumer demand for solar modular for examples which in turn can help produce the effects within the market place base upon the Supply & Demand out of urgency which the consumer market can help to create in lowering the cost of Solar / Wind/ Bio- Fuels technologies applications.

Remember That President Bush / Congress passed into law the 30% tax credit on renewable energy plus each State may have Grant & Rebates which is excellent in reduce your first solar system 1

We find in some States with Federal tax credits can help reduce cost up to 50%

Helen asks…

Why does the Tea Party think big business is on the government’s side?

The government tries to limit the power of big business, so why would big business support the government?

Shazam , I wonder why ?? While billions of “green-energy taxpayer money is gone, and we know that the majority of the loans (90 percent) were funneled to Obama and high-ranking Democrat cronies, the “troubled list is a moving target.” Thus there is no way to give an exact dollar amount what is still at risk, yet we do know that the percentage of cronyism in the failed and troubled list is hoovering around 56% (29 of the 52), until I have time to dig further.

Richard asks…

which is the world’s 1st largest eco-friendly building?

Windmill Farms answers:

You have plenty of candidates

The world’s largest solar-powered building has been unveiled in Dezhou, Shangdong Province in northwest China. The 75,000-square-meter office building is based on the sun dial structure and marks the urgency of seeking renewable energy to replace polluting fossil fuels.


Indonesian chocolate factory is world’s largest commercial bamboo structure
And sustainable it certainly is. The 15m tall structure was designed by architect Pete Celovsky, a Seattle architect now relocated to Bali who shared the company’s eco-aspirations. With considerable input from Schilling and his partner Ben Ripple, the design was developed through ‘many, many, many renditions’ to the grand structure we see today. Aside from the eco-friendly properties of the building’s core material there are two rainwater collection tanks for non-food production purposes and two black water treatment ponds serving bathrooms on each side of the building.


GURGAON: US secretary of state Hillary Clinton`s first visit to one of the world`s most eco-friendly buildings was greeted in an equally environment-friendly manner.
The ITC Green Centre is a Leeds Platinum rated Green Building and the largest building in the World to have been awarded this rating. (the second largest city in the Indian state of Haryana.)

A US investment giant has announced its plans to begin construction on what is aimed to be the world’s most environmentally friendly office skyscraper.

PNC Financial Services Group Inc unveiled the plans last week for ‘The Tower’ at PNC Plaza in Pittsburgh Pennsylvania.

Here is another one.
The Chevy Volt costs GM (government motors) $95,000 to make and the list price is about $35,000. Uncle Sam covers the $60,000 loss,
Thanks to Obama…

Ruth asks…

Why does president Obama only pick the losers when he invests Taxpayer dollars?

“A123 Systems Inc. (AONE), a maker of rechargeable lithium-ion batteries for electric cars, filed for bankruptcy after failing to make a debt payment that was due yesterday.
The company listed assets of $459.8 million and debt of $376 million as of Aug. 31 in Chapter 11 documents filed today in U.S. Bankruptcy Court in Wilmington, Delaware. Chapter 11 is the section of the Bankruptcy Code used by companies to reorganize.
A123 didn’t expect to be on time with an interest payment due yesterday on $143.8 million of notes expiring in 2016, or to make a payment due yesterday on $2.76 million in outstanding 6 percent notes, the Waltham, Massachusetts-based company said yesterday in a regulatory filing.
“The company may not have sufficient cash to fund operations and may need to seek the protections provided under the U.S. Bankruptcy Code,” A123 said.
A123, which received a $249.1 million federal grant in 2009 to build a U.S. factory, needed a financial lifeline after struggling with costs from a recall of batteries supplied to Fisker Automotive Inc., the plug-in hybrid luxury carmaker. A123 announced in August that it was working on a deal with Wanxiang Group Corp., China’s largest auto-parts maker, for financing in exchange for a majority ownership stake.”

Windmill Farms answers:

The way you phrased the question, I have to disagree – the press of course reports the losers – but there are always some losers whenever you invest money. In fact, Obama’s energy department has picked more winners than losers. You don’t read about them because they don’t make good news stories.
There’s a chart on this page showing energy investments – both clean energy and fossil energy – going back decades, all the way to the 1960s. That’s right – it’s not some new “Obama” thing, it’s been going on your entire lifetime:

Notice from the chart that the clean energy investments actually have the highest rate of return out of all the investing the DOE does. Yep, clean energy investments – despite some failures – actually MAKES MONEY for the government.

Wind Power Pros And Cons

Sandy asks…

What is the impact of Biomass on the Environment?

I need both the pros and cons of biomass. Any extra information you can give me on biomass in general will be appreciated too.

Windmill Farms answers:

Hydro power
Solar power
Tidal power
Wave power
Wind power

The above list mostly comprises of Biomass. It’s good for our planet because those energy are renewable. Less damage to the planet. So we benefit from it ;)

David asks…

How much would it cost to heat a house with oil heating?

The house is almost 3,000 sqft and I would like to know around how much it would cost? Also, what are the pros and cons to oil heating? I’ve never used it before and I would like to know more about it.

Windmill Farms answers:

So roughly an average 4 bed house.
Look into air source heating it will work out cheaper than oil boiler. Plus no big oil tank in the garden or oil deliveries to worry about. Also the eco choice with the wind power generation. 12kw won’t be enough in cold periods but with a booster heat source for very cold periods will be ok.
12kw air source approx 1200 on ebay.
Also look into trianco activair air source heat pumps.

Michael asks…

what are the pros and cons to renewable energy sources?

these include: solar energy, hydroelectricity, wind power, wave energy, tidal energy.
thank you very much big Gryph!
very good link.

Windmill Farms answers:

Solar: Pro – some sunlight every day, can be mounted discretely
Con – not much sun in the UK, panels get dirty

Wind: Pro – massive subsidies
Con – the wind is unpredictable, doesn’t work when it’s calm or stormy, massive turbines spoil the landscape, turbine noise can upset neighbours, chops up bats and birds, need massive concrete bases, need backup power stations, CO2 used in construction and transport, towers can fall down and blades can fly off. The UK wind farm subsidy scheme was developed by Ed Milliband, followed by Chris Huhne!

Tidal/Wave: Pro – Predictable, low profile, lots of potential (water being much denser than air)
Cons – high capital costs, needs more research

George asks…

What are the pros and cons of pumped storage?

Could someone please give me, in bullet points, the main pros and cons of pumped storage. Thanks :)

Windmill Farms answers:

Pro’s =
Allows you to store power from ‘constant generation’ capacity (eg nuclear) or ‘variable generation’ capacity (eg wind & wave) that is producing power at times when it’s not needed (instead of loosing it).
Allows you to use stored power at periods of high demand (instead of building extra power stations that would be idle most of the time and only needed during periods of high demand)

Some power is lost (it’s not 100% efficient)
Is based around large reservoirs at the top & bottom of high hills – so works ‘best’ where we have mountains next to valleys which = typically mean remote places (i.e. Scotland) so power has to be transmitted long distances (which means more losses and higher costs)
Almost impossible to build new ones in today’s climate of NIMBY and Political Correctness gone mad.

Betty asks…

What do you think of leaving a computer on during the night?

There are many arguments, both pro and con, that I’ve been reading lately. What do you think?

Thank you for the ideas!

Windmill Farms answers:

Yeah, there are pro/cons of this issue. On one hand, some think leaving a computer on all the time will cause parts to wear out sooner, and on the other, those who say it matters little this wearing out situation because before it ever gets to that point the computer is obsolete and it is time to get a new one anyway.

There are those who say turning off a system is important because it helps refresh the system, but others say that the idle time is important due to how Windows uses idle time to do houseworking tasks needed to keep a system in tip top shape.

Regardless of which side you fall on it is a good idea to occassionly reboot the system. This allows it to reset system configurations which would otherwise not be done. However, this also seems a bit pointless too, because after certain updates or installation of programs or hardware, or system configuration changes, a reboot is required to finish the task. So, this creates a reboot without doing so at a given time each week, or month, etc.

Today’s computers are such well built and configured in such a manner that completely shutting down the system every night is really not needed any longer. With a monitors ability to be turned off with a button, you don’t even need to worry about utility resources being wasted and running up a bill. After an individual has finished for the night, and either, puts the system into hypernation, sleep, or just leaves it on, and turns off the monitor, the system is fine and the electricity used very small if at all significant.

Sleep uses a bit more electricity than hybernation, but all in all each is a good way to leave the system. The system recovers quicker from sleep than hybernation, but the trade off is in the small amount of power saved from hybernation over sleep.

I was surprised to learn that it is a monitor which consumes the largest amount of electicity. A 17 inch monitor, left on 24/7 costs about $70.00 a year. While this may not sound like much if you only have one computer, if you are a business owner, it can run up the expense account considerably! If a business has ten computers, well, that is $700.00 a year! Just to run the monitors, not including the electricity the rest of the system uses.

I think it is perfectly acceptable to leave a system on. If you have an Always On Internet connection just ensure your system is behind a NAT router and a good firewall is used. If you are concerned about saving a few bucks on your electricity bill, turn off the monitor(s).

This is a good question because there IS still a lot of debate over which is the better way to handle a system. For each con there is a pro. So, it would be an individual preference which winds up driving how one chooses to deal with this issue. There isn’t anything one way or the other which proves preferable.
