In 2008, Mayor Michael R. Bloomberg announced his plan to use wind power to help reduce the city’s dependence on power plants that run on fossil fuels. So far, there are no large-scale efforts to harness the wind in the city, only token projects like the small turbines on the roof of an apartment building in the Bronx and a wind-powered electronic billboard for Coca-Cola in Times Square.

The city’s Economic Development Corporation has been studying the feasibility of putting turbines atop buildings, including a warehouse at the Hunts Point Cooperative Market in the Bronx. But the high hopes rest on a partnership, with utility companies and the New York Power Authority, that has designs on building a wind farm on about 65,000 acres of the Atlantic floor. The New York consortium said at the end of June that it would apply for a 25-year lease on the site, with hopes of generating as much as 700 megawatts of power there by 2016.

While city officials navigate the logistical and political shoals of that ambitious plan, other agencies are pressing ahead on more solid ground.

The Port Authority’s proposed project at Port Jersey on the border of Bayonne and Jersey City would be similar, in appearance and purpose, to a wind farm that was built at a sewage-treatment plant in Atlantic City five years ago. The authority is seeking suggestions from companies that might be interested in managing the project on how to set up the turbines. Mr. Baroni said it could be operating by 2013.

When the winds are high, the five turbines would produce as much as 7.5 megawatts  enough to run at least 2,000 homes, he said. The authority plans to use the power generated to operate the container port there, then to feed the surplus energy into the local power grid, offsetting some of the authority’s consumption elsewhere.
