The Renewable Resource Data Center (RReDC) provides access to an extensive collection of renewable energy resource data, maps, and tools. Biomass, geothermal, solar, and wind resource data for locations throughout the United States can be found through the RReDC.
Almost every area of the country can take advantage of renewable energy technologies, but some technologies are better suited for particular areas than others. Knowing the resources of a region, state, city, or neighborhood is therefore critical to renewable energy planning and siting.
RReDC provides detailed resource information through tools, reports, maps, and data collections. Additional resource data can be found on the NREL Dynamic Maps, GIS Data, and Analysis Tools Web site.
The Renewable Resource Data Center is maintained by NREL's Electric Systems Center Resource Integration Section.
