PFI - Epic fail
All PFI is, is a way to take money from the poor (via taxation) and hand it to the rich. It should no longer form any part of any state enterprise. And all these "private partners being paid by results" need to go to; it's the same kind of scam.
As for wind power...utterly useless (expect in a very few cases) and it will remain so until we have a way of storing the power for when the wind does not blow. Liquefying air, making fuel from H20 and CO2, pumping water uphill or whatever; unless we can store it, there's no point in having it.
Unless we want to be like Germany and have to import dirty coal power.
And, of course, wind power isn't very green; just ask the bats.
