There are a lot of contaminated sites in the US. Many are former landfills that are urban mounds of varying size, and they are often devoid of trees. This makes them good candidate sites for solar power or other forms of renewable energy. This is a win-win opportunity in many instances!
The U.S. Environmental Protection Agency (EPA) recently updated its RE-Powering Mapping and Screening Tool, which will now provide preliminary screening results for renewable energy potential at 66,000, up from 24,000, contaminated lands, landfills, and mine sites across the country. The RE-Powering America's Land Initiative, started by EPA in 2008, encourages development of renewable energy on potentially contaminated land, landfills and mine sites when it is aligned with the community’s vision for the site.
The updated screening provides insight into the significant potential for renewable energy generation on contaminated lands and landfills nationwide. For solar energy alone, EPA identified over 10,000 contaminated sites with the potential to install a 300-kilowatt solar array or greater. Based on mapped acreage, these sites could cumulatively host solar energy systems that capture greater than 30 times more solar energy than all renewable energy systems operating in the United States today.
