Ocean County could lose nearly $400 million in tourism revenues if a pilot project with wind turbines is placed 3 nautical miles off its coast, a new state-funded study says. But a wind farm farther offshore would have a much lower impact and would have a minimal economic impact overall if it were built off Ocean, Atlantic or Cape May counties. It could have a positive effect in some cases, according to the study by Global Insight, hired by the now-defunct New Jersey Commerce Commission. A project with dozens of wind turbines could be operating from 3 to 20 nautical miles off the coastline, from Seaside Park to Stone Harbor, in 2012. But most current proposals are for wind farms 8 to 18 miles off Atlantic or Cape May counties.

A nearly yearlong effort by the state to figure out the benefits and drawbacks of offshore, energy-producing wind farms is leaving some environmental groups less than blown away.
