"NIMBYism" is a word that turns off critical thought in some people and ruins discussions.
There is a large inventory of coastlines with wind energy potential. There will be many distractions as they are developed by coal companies trying to derail those projects. That may be through astroturfing which will present itself as "NIMBYism" and divides people to weaken them.
Additionally, a lot of densely populate coastal areas are populated quite a ways inland. You need open space around the big wind turbines for safety reasons - farmland is best.
