"Polluted brownfields offer an attractive option for renewable-energy projects in need of inexpensive property."

The article states that the EPA has stated of 15 million acres of polluted land - 11,000 sites are good for renewable projects like solar, wind farms, biomass, geothermal, and landfill-producing methane.  Gov't officials are working with developers and utilities to promote the use of such properties.

EVP of Apex Wind Energy said they secured permits in 2 months for a wind-farm at a brownfield site in NY that would normally take 2 years. 

And with polluted sites and hypocritical NEWBYS, it's hard to argue against such a use for these properties.
