There are few of them a few miles from here (central Midlothian). They're completely silent and rather beautiful. There is an ideal site for a few more turbines just above the village here, half a mile away, but I can't see it happening soon (arsehole landowner wants to use the site for housing; it's presently used for a free-range pig farm, which could easily coexist with turbines).

Large areas of central Europe have FAR more of them than we do. The only reason Britain doesn't have a serious construction programme for them is that the government is on the take from companies with an interest in coal and nuclear power stations.
