wind farms in uk, page-7

My point is governments are giving the impression they have the money to impliment renewables like wind, and after implimentation realise they still need to spend the same amount on upgrading the grid!! Take NSW for example, dropping the solar feed in tariff from 60 cents to 20.
Someone making alot of money in the renewables sector from their mates in power somewhere, without proper concerns for the people.
The question I'd like to know is, were field tests conducted over a two year period indicating expected returns on wind generation???
