Actually, the US maintains over three different tax credits on wind power.
One of them (your pick of three) is a 30% cash-back on installation cost.
And an 5-year accelerated depreciation schedule ie writeoff, where normal infrastructure is 20 years.
Another US subsidy is the 2.5c$/KWhr subsidy on produced power/kWh.
The quoted costs are typical todays costs, based on average prices in the US.
I saw somewhere a 10kW home system at 50-80.k$.
This is likely correct, and a ridiculous price, imho.
I suspect a lot of that is permits, likely mandatory, and connection charges by the power companies, of all sorts.
This is a so-called soft-cost, and is very significant in some parts of the world.
Most, maybe 99% of all installed wind power is new units, as they are bigger and taller, and thus more efficient.
I dont doubt some older units are cheap, but their relevance as in % of total power is likely very low.
We also maintain similar tax credits here in Europe, with various schemes.
Same same, but different.
Wind power is mostly a tax dodge based on getting subsiside, unlike PV today.
PV also WAS, previously, all about feed-in tariffs, but these have been mostly discontinued.
The costs were based on on actual current numbers, as per what the companies building them actually get paid.
These are pretty public numbers.
Many/Most PV companies are public, and do publish their turnover and MWhr and units produced.
Pricing is pretty public, as the manufacturers compete on sales.
PS.
Ive never been up a wind tower, but have run a harbour crane from 70M up (200 ft) and picked up containers with it.
Great stuff !
Sorry to hear your country does so poorly. In the Central and Western parts of the United States of America, Those units cost a dollar a watt INSTALLED, and the subsities are all but dried up for either installation OR O&M. There is a thriving secondary market that refurbs them, and resells them for 3/4 of new or more. There is a lot of propaganda out there, mostly by ultra-progressives or extreme right-wingers, ALL of which have never "rode a mill", (much less owned one). It has been one of my most exerilerating experiences to do that. From hanging on a belt under a 500Watt home unit atop a 60' lattice tower, to a 1.5 Meg monster at the end of a 320 foot tube tower, the feelings your get are a real rush. I am so glad I have had the gumsion to actually get out of the computer chair and do some of this stuff. Owning and maintaining a farm, any size, is far more authouitative than reading somebodies opinion in a rag somewhere. I know, I have been in both places.
