I looked at some numbers here, just looking at the steel alone (60-70 of the mass of a wind turbine)
Mass of steel = 201 tons
coal needed = 0.770 * 201 = 154
energy in coal = 24 * 154000 = 3,696,000 MJ
assuming 25% operating capacity,
3,696,000 = 2 Mega Joules per second * t seconds * 0.25
=> t = (3,696,000/2)/0.25 = 7,392,000 seconds = 85 days

That doesn't really debunk it, it just says that you have to place them in "good" wind places.
It fails to mention that the wind can't be too good since wind turbines have to shut down if the wind makes them spin too fast or they risk burning it out, so they generally just shutoff at wind speeds of 55+ MPH.

I live in a city of 225 km^2 filled with cats and birds and I can't remember the last time a cat killed a bird. You have to be insane to believe cats kill 2.4 billion birds in the US. If there is 1 cat/10 mutts that's 40 million cats, 2.4B/40M = 60 birds/cat/year killed, that's 1 bird every 6 days.

Lets see 260 tons of steel. Whats the cost to move that around? Variable since it depends on the location.
The biglow canyon wind farm has 450 Mw of windmills installed. Its located about 120 miles from Portland, which has a steel mill (evraz oregon steel mills)
A cargo of 270 tons of steel can be carried by 10 18 wheelers. With a fuel economy of 10 MPG it cost 12x10=120 gallons to move that steel. Thats about 450 liters of diesel which are equivalent in energy ti about half a ton of coal.

I have always thought this actor was intensly ugly, so ugly I have never understood why he is famous. I cannot even look at his face. It's awful.

2 MW is tiny by today's standards, 10 - 15 MW is the norm.
And is 260 tons steel correct? Battle tanks are about 50 tons and 5 m long, so with an armoured shell you get 25 m tall tower. This seems a bit suspicious.
