Layer displays the locations of contaminated mines, landfills, and industrial sites evaluated by the US Environmental Protection Agency (EPA) for their renewable energy potential. Sample layer shows sites screened for wind-power only.
This layer shows the location and production of coal mines within the United States
This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. This product is a digest in which the fields chosen are those most likely to contain valid information.
Electric Bulk Power Transmission Lines
This layer represents electric power transmission lines. Transmission Lines are the system of structures, wires, insulators and associated hardware that carry electric energy from one point to another in an electric power system. Lines are operated at relatively high voltages varying from 69 kV up to 765 kV, and are capable of transmitting large quantities of electricity over long distances. Underground transmission lines are included where sources were available.
Natural Gas Pipelines
The U.S. natural gas pipeline network is a highly integrated network that moves natural gas throughout the continental United States. The pipeline network has about 3 million miles of mainline and other pipelines that link natural gas production areas and storage facilities with consumers. In 2017, this natural gas transportation network delivered about 25 trillion cubic feet (Tcf) of natural gas to 75 million customers.
About half of the existing mainline natural gas transmission network and a large portion of the local distribution network were installed in the 1950s and 1960s because consumer demand for natural gas more than doubled following World War II. The distribution network has continued to expand to provide natural gas service to new commercial facilities and housing developments.
This layer shows the location of eletricty gernerating power-plants in the U.S., the total capacity of each plant, and the primary fuel source.
Emissions & Generation Resource Integrated Database (eGRID)
This layer displays the locations of the Environmental Protection Agency (EPA) Emissions & Generation Resource Integrated Database (eGRID) sites. The eGRID is a comprehensive source of data on the locations and environmental characteristics of almost all electric power generated in the United States.
