Does that actually make any sense when there is also plenty of wind across the ocean, which is >1000 miles closer to the coastal cities where people live?
Tends to have a lot of unfortunate pushback from the well-connected people who like to live on coastlines.
Offshore wind power costs ~3 times more per MWh than on land. You can still do it if you're really low on space, but if you have tons of empty space anyway, it may very well be cheaper to simply build longer power lines.
