I will summarize later but just to show wht the facts are
To address the energy requirments to produce fiberglass used in windmills and to identify the companies who are getting rich each of the materials in the report must be researched, where are the mined, where do they come from, who manufacturers these materials, what is the energy requirement for each individual material, than we must add those numbers to the fiberglass production numbers.
I have a shitload of files but just aint put them together. If anyone thinks answering my simple question was simple they would of done it, green energy is not as simple as stating its a good idea. Folks beleive in green energy without an understanding of the industry it takes to make the basic materials.
I will try and avoid articles and post reports, this one from the EPA
Raw Materials Handling -
The primary component of glass fiber is sand, but it also includes varying quantities of
feldspar, sodium sulfate, anhydrous borax, boric acid, and many other materials. The bulk supplies are
received by rail car and truck, and the lesser-volume supplies are received in drums and packages.
These raw materials are unloaded by a variety of methods, including drag shovels, vacuum systems,
and vibrator/gravity systems. Conveying to and from storage piles and silos is accomplished by belts,
screws, and bucket elevators. From storage, the materials are weighed according to the desired
product recipe and then blended well before their introduction into the melting unit. The weighing,
mixing, and charging operations may be conducted in either batch or continuous mode.
Glass Melting And Refining -
In the glass melting furnace, the raw materials are heated to temperatures ranging from
1500 to 1700°C (2700 to 3100°F) and are transformed through a sequence of chemical reactions to
molten glass. Although there are many furnace designs, furnaces are generally large, shallow, and
well-insulated vessels that are heated from above. In operation, raw materials are introduced
continuously on top of a bed of molten glass, where they slowly mix and dissolve. Mixing is effected
by natural convection, gases rising from chemical reactions, and, in some operations, by air injection
into the bottom of the bed.
Glass melting furnaces can be categorized by their fuel source and method of heat application
into 4 types: recuperative, regenerative, unit, and electric melter. The recuperative, regenerative, and
unit melter furnaces can be fueled by either gas or oil. The current trend is from gas-fired to oil-fired.
Recuperative furnaces use a steel heat exchanger, recovering heat from the exhaust gases by exchange
with the combustion air. Regenerative furnaces use a lattice of brickwork to recover waste heat from
exhaust gases. In the initial mode of operation, hot exhaust gases are routed through a chamber
containing a brickwork lattice, while combustion air is heated by passage through another
corresponding brickwork lattice. About every 20 minutes, the airflow is reversed, so that the
combustion air is always being passed through hot brickwork previously heated by exhaust gases.
Electric furnaces melt glass by passing an electric current through the melt. Electric furnaces are
either hot-top or cold-top. The former use gas for auxiliary heating, and the latter use only the electric
current. Electric furnaces are currently used only for wool glass fiber production because of the
electrical properties of the glass formulation. Unit melters are used only for the "indirect" marble
melting process, getting raw materials from a continuous screw at the back of the furnace adjacent to
the exhaust air discharge. There are no provisions for heat recovery with unit melters.

So your argument would be that COAL POWER PLANTS grow from a MAGIC bean that we plant and water until a FULL FLEDGED power plant grows. If you want to be HONEST with your argument about windmills/solar panels then you have to DIRECTLY contrast the costs and the materials INCLUDING the mining of materials. Then you would have to CONSIDER the technology LEAPS that wind and even more so solar power have undergone in just the last ten years.
I think we STILL pretty much BURN coal/natural gas and I doubt we have come up with many REVOLUTIONARY new ways of doing so. They may be a bit more efficient and produce less pollution than they did 20-30 years ago but they are 100 YEAR OLD technology I mean my Gawd man how long should we keep doing the SAME F'ING thing until the fossil fuel runs out? Now there are many different views on just WHEN fossil fuels will run out but whether it is 50 years or 200 years if we REFUSE to utilize NEW technology then we will be in a REAL BAD WAY when change is FORCED on us.
Sorry I had to disappear from this thread so long ago but I have a very full life and when I have the oppurtunity to live it I make no time for the petty arguements I find myself in.

So you think Wind power is a new alternative, I disagree, Holland has used windmills for 100's of years.

I have addressed Wind Power, it uses too much energy to create.
Solar, I guess that grows from the "MAGIC" bean, if only we pour more money into the technology it will work. Solar technology is old, I say at least 100 years old, we have spent billions of dollars on Solar technology since that time and it has come a long ways since the first Solar plants were use to heat water.
For some they see Wind and Solar technology as a newly discovered plant growing from a MAGIC bean that just needs a bit of pruning then we can harvest its fruit.
Not that this is a scholarly arguement but I just drove by California's largest solar plant and I paid paticular attention to the power lines that come from this solar plant of the I-395 highway, the power lines were nothing more you than what you would see in any city with a population of around 5,000 people.
The power from Solar is tiny, miniscule, insignificant and this is after 100 years of technology, research, and billions of dollars spent.
