From the Introduction: "This report provides an overview of U.S. energy issues, and it serves as an initial resource document for related information, data, and CRS [Congressional Research Service] contacts. The report is organized around the major fuels and energy sources used in the United States. It also highlights the role of the federal government, particularly the use of federal lands in energy production. It does not focus on security, research and development, or environmental issues, although those subjects are also critical to the U.S. energy sector."
