The RE-Powering Mapper, an Environmental Protection Agency interactive tool to show renewable energy potential on contaminated sites, was updated August 6, showing a rise in potential projects from 24,000 to 66,000. The agency and the National Renewable Energy Lab looked for contaminated land, landfills, and mines for capacity to sustain biomass, geothermal, solar, and wind projects. The initiative began identifying sites in 2008.
