I was recently up in Cambria County, PA on a hunting trip. They've been putting up wind farms in the area (in fact, they even built a windmill blade factory). I've never seen modern windmills up this close before- you can see them from pretty far away on the ridges of mountains and stuff, but you don't really get to appreciate the scale of these things unless you're up close. They're HUGE.
This is a blade on the bed of a truck. You could stand inside of it.

Here are some assembled windmills.

The box at the top is somewhere between the size of a pickup truck and a short bus.

Hmmm... pictures really don't do them justice, it seems.

Pretty cool stuff!
-
Very cool.

Just one small point of detail: these are wind generators or wind turbines. Only if they are used to pump water or grind something are they referred to as windmills.
-
we have about 500 of them in Kansas. I believe by 2010, we will have 1500. They are a small help on energy but a huge impact on the ecological environment.
-
I remember about 11 or 12 years ago I had to do some field work for the factory I used to work for and saw a bunch of these (guess they call it a field) in Iowa. They are indeed an awesome site to see in their finished form but I am sure you probably get a better feel for their size in the pre-assembled form as well. Great pics man :aok

how so?

The argument most often cited is that each megawatt of electrical power created requires 6450 barrels of oil and creates 2700 tons of CO2 49 tons of SO2 5.5 tons of NOx and 175 tons of slag and ash for a landfill for a return of enough power for 650 homes. I dont believe that much polution comes about from producing a single megawatt but thats the claim.
These turbines are ugly noisy and create electromagnetic interference as well as kill birds (how many exactly has yet to be determined) and will not produce power reliably (no wind no power).
My argument against rushing to build these 'farms' and large numbers is the same as for any such 'rush to satisfy whims' that men chase after. How many people yell and scream about global warming convinced that man is dooming himself and yet we cant predict weather and we cant control it. Now it comes to this radical rush to create alternative power and we let brainless politicians with no understanding of weather economy ecology or the impact on constructing these giant farms all over the country upon our world. They are going to create a bigger mess then they had before; government always does this without proper consideration.

I'm curious, how many birds are in Holland? Been windmills there for centuries.
I see those go by my house almost daily. They are building a huge windfarm about 30 miles from here. The boxes are the generator. It measures 15 ft tall, 10 feet wide and 30 feet long. The blades are 90 feet long.

I work for Iberdrola. 39 percent of our overall output being produced by renewable sources, making us the largest wind energy operator in the world. (I am at a Natural Gas turbine plant)
Bird strikes are a problem with lattice towers
(http://www.reuk.co.uk/OtherImages/lattice-wind-turbine-tower.jpg)
Because birds perch on the lattice work and then fly off into the rotor. Most of these turbines are in the 250 kw range.
New turbines are 1.5 Mw and up, 80 meters to the hub and more, do not have lattice towers.
(http://www.monsterguide.net/how-to-build-a-wind-turbine.jpg)
The rotor rpm on these big rotors are much slower than the smaller turbines, and bird strikes are very rare. We have a Audubon society crew that goes thru our farms, and last time I talked to one (in bay area CA) they hadn't found any harmed birds in several months.
As for electromagnetic interference, the field strength you get living on a farm around these towers is less than what you get from your TV set.
When the wind does not blow, that is when we have the natural gas turbines and (in the NW) Bonneville Dam. When the wind does blow, we can fill the grid with carbon free power that does not cut up salmon.

Ummm Global warming is just a single issue.. Another issue is making us self sufficient for our energy needs. Are you saying making us self sufficient is just a need to satisfy a whim? Not to mention it's renewable and creates jobs here in the US vs oil jobs in other countries.

5.6 million BTU/barrel of oil.
25 million BTU/ton of coal
At our natural gas cogeneration plant, we produce 1 kW-hr for about 7000 btu. (that's referred to as heat rate)
In a year, 61,362,000 btu/kw-yr thats equiv to about 11,000 barrels of oil / Mw-yr
At a coal plant, a good heat rate would be 12 to 15,000 btu / kwhr
In a year, 13,500 * 24* 365.25 = 118,341,000 btu/kw-yr thats 4730 tons of coal / MW yr
The amount of fuel burned in a 1.5 Mw wind turbine = 0

Im all for being self sufficient as a nation. That will never happen. Maybe we can get off of the Arab oil addiction but there will always be another addiction come along. What I am saying is these turbines are making someone a lot of money and you should always follow the money. I think this trend is all about money and not about ecology at all. Our economy needs the expansion but I am not at all sure this is a good energy solution.
-
They have even large ones, Ive seen them on cargo ships coming into LA harbor, dont know how they plan to move them, heli lift maybe
-
I am not at all sure this is a good energy solution.
Yeah, because being held hostage by OPEC is the way to go.
-
I think we have better solutions then staying slaved to OPEC. We have our own sites to drill. All the turbines in the world wont give us more gas for our cars.
-
Dooo eeet all.
Windmills, tidal, solar and drill. Let the opec countries eat that oil. :aok

Well if you dont need to use oil to produce electricity you can import less.
Supply and demand.

Just love how this went from one person saying how impressive these structures are to an indepth discussion on whether they are actually helping or not.

Motherland, i live in Center Valley Pa, ( a little south of Allentown) and had the opportunity to see those windmills while driving to Pittsburgh on a business trip. I know the wind generators you are speaking of. They are HUGE. I actually pulled off the side of the road and was probably a 1/4 of a mile away. I could not imagine being right on top of them though. From that distance i still had to move my head up to see the tops of them. :salute

Very cool, thanks for posting the pics! :salute

Right now before it hits, if these things take off you can get wind energy stocks dirt cheap. an ETF with the symbol FAN is an example. FPL is more expensive. WND.V, GRH, CPTC.OB are others. Newish companies so not a lot to go on but for the few bucks they cost me I felt it was worth buying in and taking a wait and see.
-

IIRC most of our electricity is from coal and natural gas when we use a fossil fuel for it.
-
I live just north of Houston and I see the blades being trucked all the time on I-45.
HUGE!!!!!!
-
Well if you dont need to use oil to produce electricity you can import less.
As Maverick said, the US uses very little oil for power generation. US electricity generation by source, 2006:
Coal - 49%
Natural Gas - 20%
Nuclear - 19%
Hydro - 7%
Renewables - 2.4%
Petroleum - 1.6%
Even the 1.6% provided by petroleum is produced by burning petroleum coke and residual fuel oil, two by-products of the refining process that aren't much use for anything other than firing boilers.

Well, the windfarms where alot smaller. But, if you want to really know why these huge windfarms are such a problem with wildlife, i can send you to this web site.
"Though birdkills at lighthouses had been noted for centuries, it is unlikely that anyone anticipated the often large number of songbirds that would be killed at tall TV towers which were lighted at night for aviation safety. People began documenting bird kills at tall communications towers in North America during the late 1940s - such towers were then being constructed on the continent to broadcast the emerging television medium. As happens with lighthouses, on foggy or low cloud- ceiling nights, migrating birds seem to be attracted to the lights on the towers, mill about them for lack of stronger navigational cues, and became apparently disoriented. Mortality at these towers was chiefly attributed to collisions with the guy wires used to support the towers. Though tragic, large kills appeared to be relatively rare, up to and including the 1980s and 1990s, and there was little evidence that anyone thought songbirds were declining as a result of collisions with towers - the birds seemed abundant. Nonetheless, the kills were appalling to bird lovers and towerkill studies began at a number of tall towers across the continent. Most ornithologists and a small portion of the public became aware of the periodic bird kills. A decline in the number of towerkill studies and diminished attention to the issue occurred during the 1980s and 1990s. Now, with the recent erection of thousands of new, even taller towers, the potential for increased avian mortality has again brought this matter to the forefront." -Al Manville, Ph.D.

Even though we are talking about wind Towers, it is the same concept of them circling around the light but hitting the blades. During my college years, I was on a research team studying tower kills. In one night at a 150ft tower, we found 42 individuals that where kill by the tower. In the last five years, biologists are seeing a huge kill on bats from wind towers.

Coal: Non renewable.
Natural gas (pumped out): Same, (just not the same co2 factor.)
That's 69%.
And energy, as petroleum, is mostly used for transport etc. An alternative source such as wind must be a good thing for a country.
However, I always feel those big ones as butt ugly. Living in a country with lots of wind, Im still looking for a 5-10 KW wind generator for the household.
Anyone???

if you find one let me know angus. i lil wind turbine in the back yard would really spruce up the ol' neighborhood :eek:
considering my electric bill over the summer :O i could care less what the neighbors think tho

Depends on your summer wind. 5KW may need quite a prop in your place, while in my windy place...not ;)

What the hell are you using all that energy for? Grow lights in the basement?
1500 watts sould be plenty enough for a typical household electrical load.
Unless you are not geothermal.

you can buy several and hook them up to provide your required KW. (plus side if one happens to fail you'll still have power from others)
http://www.windenergy.com/documents/spec_sheets/3-CMLT-1341-01_all_product_spec.pdf
one provides over 500 KWh/month @ 12 mph (5.4 m/s)

Ahemm.
I know you are well in on power usage, but it's a bit simple to state things like that knowing none of the factors involved.
1500 watts is enough to warm 3 bedrooms, and that's it (minimum, radiators are from 500 to 1500 W). Well we do get a good gale and minus 20 degs celcius at times. Average outside temp in the winter is...cold.
4 kw for cooking....when you're at it.
The water heater takes 1.5 KW. Like a shower warmer than 4 degs celcius?
In my case (7 rooms + living quarters+ boiler) some 5-10 KW would be just fine, and that would mean everything but the boiler and radiators running on the local powergrid.
A friend of mine had a 30 KW water turbine in his creek. He would still have trouble with fluctuations, - turn on some power (Like cooking big-time) and your lightbulbs pop.
I have the wiring seperate, so that the radiators can be on a seperate part, - this was intended from the start!
(7x1000 = 7 KW, then the 1.5 for the boiler... = 8,5)....
BTW, On the grid I was cruising on the total of 9 as an average.
5-10, sounds good ;)
-
This one looks allright!
http://www.windenergy.com/products/whisper_500.htm
At a good gale, 3 KW. That's a start.
I have a silo here that stands some 36 feet high. so there are possibilities....

Hey Angus, that's why I added the "unless you are not geothermal.
I know virtually all Rekevjlrskik (sp) is geo heat, I thought maybe you might be close enough to the capital to be on the loop, or as it is here in Klamath, maybe you dropped a well to get some hydrothermal to heat your home.
If you can get some hot water, it's a wonderful way to heat.
I am designing a system for a couple in town to run a refrigerant-134A system that should come out at something like 1 kw that will electrify their home, and the waste heat either heats their hoome or runs to a loop of pipe under their back lawn and through their greenhouse to condense the r-134A to pump it back to the boiler/turbine.
The engine/generator, and heat exchangers fit in a 1 cubic meter volume.

i know that. The wind towers just adds more deaths for the birds.

Sexual activity adds more birds to the environment.
It's the circle of life, Simba.
-
if only you knew how high the mortality rate is for birds migrating. Lets say that in one summer, you will have 1 billion new born (THAT IS A SMALL NUMBER). From the day of their birth to there final migration destination, only 1% of that 1 billion new Born will make it. This is concider a high mortality rate. Over 200 yrs, it is estimate that 10-20% will survived in there first year of there lives. Majority of the deaths are from man made objects, like the TV and radio towers. It is believed that TV and radio towers kills over 10 million birds each year.

The bird death rate is the same as it has always been, one per bird.
Denholm, don't try to add logic and reality to the situation. It adds nothing to the emotional pap that make some SO happy to swill.

Death rate has not been the same. It has increased especially in the last century and half.

Who cares about a bird getting killed by one of these things? The bird that does die is the stupid one anyway for flying with it's eyes closed. And it's not like a windmill or 1 million windmills is going to put even a small dent in the worlds bird populations.
Geez people that worry about stupid stuff like this are idiots. Here's what you do if your near a windmill and a bird runs into the thing and dies. Pick the bird up, skin it, cook it, and eat the thing. Now your getting free power and a free meal as well. Win, win for everyone.

Yet, you have NO idea what kind of damages that can follow just from one species of bird disappearing do to human influence. In fact, you don't know a dam thing about the ecology and behavior of birds.
Just fly away from this post.

Sure I do. I study the migratory patterns of Canadian Geese, and ducks. Phesant, Dove, Quail. You really have to understand their patterns, eating habits, what sort of cover they like to hide in if your going to go blast them out of the sky with a shotgun so you can eat them for dinner.
I've been an avid bird hunter for 20 years. I probably kill more birds in a single year than 1000 windmills will kill in 10 years, so sorry if I don't break down and cry over some sparrow that gets whacked by a freaking turbine blade. The fact that you do actually makes me laugh rather hard. "Ohhhhh the poor wittle birdie :cry)
Give me a break.

I am talking about all species. Not just game birds. Now, if you kill more birds in a single year than 1000 windmills kill in ten years. I am guessing that you kill over 1 million birds. WOW. Once again you demistrated your lack of knowledge on the bird ecology and behavior. geesh

I am lost. Are you saying that the bird death rate has been the same for the past 200 yrs?
-
Getting back on track, - from birds, - those generators seem to be able to produce the KW for some 9 cents, as well as I understand, and that means by paying up the project in 4 years.
Not bad, if your powerbill is 9 cents pr KW anyway, so you have free electric (mostly, - there is maintenance perhaps) in 4 years.
Are these numbers right?
BTW, where I live (Iceland) the power cost seems to be similar (9 cents/Kw), but the wind speed is very much more as an average, so you'd have the generator running nicely ;)

The best source of FREE power is solar panels. In fact, the newest solar energy is solar film. Thin as paper, cheap to produce, make in mass production and as efficient as the paneles. the best part of it is you can attache it on your roof, window, siding, and working on adding the element in paint. it will save up you to 50% of energy cost
-

yes. 100% of everything born dies.

So the panels, installation and maintainance is free? Sweet!

I'll wager that cars and airplanes kill more birds than these towers. Add in cats, hawks, trains, electricity, weather, poison, and the natural aging process, and we've virtually guaranteed that 100% of all birds will be killed off within their lifetimes.
That is positively terrifying, isn't it?
Back on topic- I saw a couple of blades go by on railcars a few weeks back- the train was moving at just a couple MPH, and it took me a while to realize what they were- the pictures truly don't do them justice. They are just enormous. I haven't seen larger pieces of equipment outside of a steel mill. Very impressive.

Cars maybe but the majority of airplanes are usually in a bird strike zone for very little of their flight. Im not really worried about birds anyway but more concerned about a bunch of tree huggers and money grubbing politicians selling us a bill of goods.

i used to think they were fans and called it the wind factory when i was small.
always thought they were smaller than they seemed but now with those pics, WOW

If you are using electricity then change over to a ground source heat pump (Geothermal). Some units have a COP of 4+ at this rate for every dollar you input you get four dollars heat. :aok

Could you bring some more data on that?
-
If you are thinking ground source heat pump you might want to check out an Acadia system instead. Rumor has it that this air source HP is nearly as good as ground source ones.

It is sometimes costly, - where I live heating up with electrics is about the same, but less investment when building. (The source is far away so there is cooling and pumping costs etc)
But the wind is steady and ample.
With more and more trees being grown, quite many partially heat with wood, - and it's cosy ;)
