Hi Buddy,yeh there are hundreds.We call them wind farms as they are usually sited all together well out in the countryside and normally on very high ground,rather like flocks of sheep,or herds of cows(a bit collective noun action their).Energy sustainability is becoming a big thing nowadays and quite right too,why not harness Mother Nature.We also have wave technology being tested at the moment as the sea can be very rough especially round our more northerly coastline but not exclusively.I think I mentioned to you about my mum's family coming from Fair Isle,well log onto their and there is some interesting stuff on wind and solar power.👍
