US advances on clean energy with first offshore wind farm

Offshore wind farms are in development across the country, but the election of Donald Trump may weaken federal support and squelch an emerging industry

Several miles off the coast of Rhode Island, a clean energy landmark quietly just powered up.

Five 560-foot-tall wind turbines are now spinning their 240-foot-long blades, sending electricity out onto New England's regional grid. The wind turbines, which are connected to the sea floor via steel foundations, are linked to the broader grid by transmission cables deep under the sea.
