A Massachusetts business group is strongly backing the Cape Wind offshore wind project, after two other business groups recently attacked the project in newspaper ads.

    The Alliance for Business Leadership called Cape Wind ``an historic opportunity'' in a statement Wednesday.

    Last month, the Associated Industries of Massachusetts and the Massachusetts Competitive Partnership took out the full-page ads saying the above-market cost of Cape Wind's power will make the state less competitive.

    The partnership's opposition was notable because of its prominent leadership, including Patriots owner Robert Kraft.

    The alliance also has well-known leadership, including Panera Bread founder Ron Shaich and Zipcar chairman Scott Griffith.

    It says the 130-turbine project, which aims to be the nation's first wind farm, will give Massachusetts a chance to become a major energy producer and lead a new industry.  (Associated Press)
