OK. I agree that their nacelle housing is fiberglass, but it so light that they don't even list the weight. If you look atAccording to this document it looks like the tower is steel, I still say no, seems like an awful amount of steel, but either way steel is better, much more expensive, much more polluting, much more wasteful. I will look a bit more.
Of course this document also states the Nacelle is fiberglass and from what I have posted and found out the Nacelle only has a fiberglass covering, this document states the opposite, simply the Nacelle is fiberglass. Lets see if you can admit when your wrong as easily as I admit when I am wrong. I will type the info, dont seem to know how to cut/paste on this paticular pdf

7.16 Nacelle
Material Fiberglass
7.15 Nacelle Bedplate its metal, because it has to be able to crane lift the gearbox and generator, which are very heavy, actually 91 Tn.
Here is a link to S355 steel, its apparently a weathering steel like is used on bridges. Its a plate, which makes sense since they roll it into the tower shape. s 355 j2 | s355 steel plate | s275 steel plateJust below this section it states the tower is S355 steel, did you know the number in steel such as this represent the other materials in the steel, like magnisium or cobalt or carbon or other stuff, I should look it up to sound so much better educated but the numbers represent the .03 percent material used, second number being another material of .05 percent and the last the same, I could be wrong on percentage but doubtful. I should know but once you learn this you never use this fact again in my business.
Anyhow the tower cannot be pure steel as this brochure states just as we know the Nacelle is not pure fiberglass as this brochure states
It makes no engineering sense to make the tower out of fiberglass.
Nice research on the nacelle housing, but it doesn't change the fiberglass weight significantly.
