Offshore Wind Energy and Fishermen

Environment

Offshore wind can be a big business, and property that is windy with shallow water is perfect for installing and maintaining wind turbines. The federal government has leased sites for developers to build industrial-scale wind farms over the next decade. The area of New Bedford, Massachusetts, which is close to Rhode Island and New York, is an area with a sustainable wind source. The developers are very engaged with fishermen in the area, since the spinning blades confuse the instruments they use to navigate through fog. By working together, turbines can be put in locations that won’t interfere with fishermen’s routes. Listen to hear more about offshore wind projects in this area.
