There is an eight page spread in the current issue of New Sector - the magazine of democratic enterprise and community control - devoted to renewable energy co-operatives. You can read it here
Didn't realise there were so many. But as the editor David Parker points out elsewhere in the magazine. "If community co-operatives generating power from renewable resources is such a good idea why aren't the Brits doing it? ...but there impact is tiny compared with Denmark where about 80% of wind generating capacity is community owned."
There are plans for water powered turbines in New Mills, Derbyshire which isn't far from here...I can see a trip coming up.
