Wind Farms and RSPB

I read this in a recent 'Spectator' article and found it depressing and disappointing.  What is the truth of the situation RSPB?  I'm totally opposed to wind farms as they are ineffective, costly and damaging to our wild landscapes.  Where I live near Corwen we are faced with the threat of 25 turbines, measuring 475 feet in height, at the foothills of the Berwyns and on the edge of an AONB.  This is the extract from the magazine: 'The big conservation organisations have been disgracefully silent on the subject, like the Royal Society for the Protection of Birds, which until last year took generous contributions from the wind industry through a venture called RSPB Energy. Even journalists: at a time when advertising is in short supply, British newspapers have been crammed full of specious but lucrative 'debates' and supplements on renewable energy sponsored by advertising from a cohort of interest groups.'
