Large-scale floating offshore wind power is finally here

Sami Grover for TreeHugger:  Offshore wind energy has been growing like crazy in the last few decades—so much so that there's even talk of serious talk of multi-gigawatt offshore wind farms in the US in the not too distant future.  But offshore wind has so far been limited to areas where the seafloor is relatively shallow, and where it's easy to build foundations for these gigantic turbines.

Floating wind turbines are different. Instead of using fixed foundations, they are anchored to the sea floor using cables. And that means they can be located in deeper waters, opening up many more areas where wind conditions are favorable and concerns about views and/or bird migration routes are less relevant. Alongside opening up new areas for development, the other major advantage of floating turbines—once they are being developed at scale—could also be reduced costs.   Cont'd...
