CT: The boundaries for locating new offshore wind turbines are constantly changing. Building wind farms out at sea provides stronger and more stable wind resources, as well as a solution to avoid disturbing the local environment and the view shed from the shores.

N: 1. off-shore (adj.): also off shore, 1720, from off (by c.1200 as an emphatic form of Old English of, employed in the adverbial use of that word) + shore (“land bordering a large body of water,” c.1300, from an Old English word or from Middle Low German schor “shore, coast, headland,” or Middle Dutch scorre “land washed by the sea,” all probably from Proto-Germanic skur-o- “cut,” from PIE (s)ker- “to cut”). American English use for “other than the U.S.” is from 1948 and the Marshall Plan.
turbine (n): 1838, from French turbine (19c.), from Latin turbinem (nominative turbo) “spinning top, eddy, whirlwind, that which whirls,” related to turba “turmoil, crowd” (see turbid). Originally applied to a wheel spinning on a vertical axis driven by falling water. Turbo in reference to gas turbine engines is attested from 1904.
2. Whereas today’s offshore turbines are typically built 10 to 20 km from land, it is expected that in five to ten years from now, wind turbines will be situated up to 80 km out to sea – at depths of 60 meters. Prototypes of floating foundations that will be used for this purpose already exist for offshore wind turbines in Norway and Portugal. So, in principle, it will be possible to build wind farms as far out to sea as you want.
