This stuff has been used for years, ever drive into palm springs / palm desert CA from the north ? pretty ugly stuff if you ask me.
It's clean, but the bang for the buck isn't that great. If they must build this off the south shore why choose one of the only natural structures we have as a site ? Put it out on open bottom somewhere. Also, cholera lies in the shipping lanes (or between, depending on where you look), we have'nt been able to prevent the ambrose tower from being hit, these things are sitting ducks. Move it further east, away from the confluence of the new york harbor shipping lanes.
Another thing, those cables have to come to shore somewhere. Seaford is up in arms about the cable they want to bring in from NJ. It would land in Cedar creek sewage treatment plant / park. Nobody wants it, plus they will have to lay cable in the bay. Not to mention the conversion plant that will be built where the cables touch land. This is another aspect of these projects that often goes unnoticed.
The real deal is the use of hydrogen and aluminum fuel cells, which are 100 % clean, and can generate electric on site. Verizon has (or is about to)powere their Garden City phone switch center using a hydrogen fuel cell for primary power. These switching centers need a lot of juice. They are telling LIPA to go scratch ! The benefit of clean energy genenation on site is that you don't need to transmit the power anywhere, so you don't need ugly, dangerous cables strung all over the place.
Windmills and solar are temporary measures. If we must build, let's use some common sense (read - Don't put them near me or my fishing grounds).
