A single blade from a turbine is 100 feet long. The turbines must be several feet apart. There can be miles and miles of land with turbines making fencing them in, impossible in reality. A restructuring/redesign looks feasible. And, expensive. Best to replace current designs with newer more efficient ones, and new fields with new designes.
Harnessing natural power has a way to go, yet.
I’m not a big fan or replacing unless they can operate from a different mindset that they did the last time.
These versions don’t make money.
Best to just take the ones we have offline.
