Solar landfill

A solar landfill, also referred to as a brightfield, is a former landfill site that has been transformed into a solar array or solar farm. Landfills that are no longer in use are often called brownfields due to potential environmental concerns. By repurposing these brownfields into solar fields, they then become brightfields. In the United States, there are more than 10,000 closed or inactive landfills, which have the potential to accommodate over 60 gigawatts of solar installations.
