  • Siting Clean Energy on Brownfields

    Renewable energy, such as wind and solar, can be sited on land that has been or is perceived to be polluted and is now underused. These properties, called brownfields, may be particularly attractive because these types of renewable energy installations may require large sites, and brownfields are usually large sites located in areas with the existing infrastructure needed to support development.
