Researchers at the Argonne National Laboratory have developed an interactive online mapping tool that can help identify areas across the United States that are suitable for wind, solar, and other clean energy infrastructure projects. First publicly launched in 2013 as the Energy Zones Mapping Tool (EZMT), the solution has been redesigned, rebranded as Geospatial Energy Mapper (GEM) and re-engineered. the solution offers data regarding existing energy resources and infrastructure, and other information that might influence new energy infrastructure siting decisions.
