wind farms

hi there every one for the past while now i have had problem with wind farms as the fully storey is not know about them the key problems I have are this
1.Howmuch metal is used to make each wind turbine is this recycled metal or newly smelted .

2.how much oil/grease is used to lubricate the working parts and if any problems could happen to the
wildlife if a large amount was to leak .

3.how much and what type of cable are they using to supply the energy to what ever sub station it goes and the environmental impact for wildlife as the trenches are being dug for these cables also how there sourced
Yet again newly made wire or made from recycled martial and the plastic that insulates the wire

I’m not closed to green energy but I see things like the Joe cell and think what the hell are we doing wasting time on wind farms when we could invest in some thing that A. does not look bad in an environment and is not really that effective unless there is a lot of wind and given enviroment change what is a good wind farm area this year may not be one in 10 years my closing point is mainly this green energy good but giving work to a company via government targets is bad

Thank you to who ever reads this
