Renewable energy in Scotland sited on a sandbank in the Solway Firth. The United Kingdom's largest onshore wind farm (539 MW) is at Whitelee in East Renfrewshire. The Clyde Wind Farm is a 548 MW wind farm under construction near Abington, South Lanarkshire, Scotland, which will be Europe's largest onshore wind farm when completed. Two very large offshore wind turbines (5 MW each) are located in the Moray Firth. There are many other large onshore wind farms including some, both planned and operating, which are in community ownership. The siting of turbines is sometimes an issue, but surveys have generally shown high levels of
Firth "firth" (e.g. the Minch and Loch Torridon); instead, these are often called sea lochs. Before about 1850, the spelling "Frith" was more common. A firth is generally the result of ice age glaciation and is very often associated with a large river, where erosion caused by the tidal effects of incoming sea water passing upriver has widened the riverbed into an estuary. Demarcation can be rather vague. The Firth of Clyde is sometimes thought to include the estuary as far upriver as Dumbarton, but the Ordnance Survey map shows the change from river to firth occurring off Port Glasgow, while
