The city also plans on cutting its carbon emissions through greater use of renewable energy.
At a Brooklyn sewage treatment plant, pictured here, it's partnering with National Grid to collect natural gas -- produced when sewage decomposes -- and pipe it into homes for heating in Brooklyn, Queens and Staten Island. A similar pilot program is under way to collect food waste.
On the site of Staten Island's former Fresh Kills landfill -- once the largest landfill in the world -- the city plans a solar panel array capable of powering 2,000 homes.
There's even grander plans for the waters offshore. The city is lobbying the federal government to allow the construction of a massive wind farm -- capable of powering up to 140,000 homes -- 20 miles off the southern tip of Manhattan.
