The Energy Independence and Security Act of 2007 (originally named the Clean Energy Act of 2007) is an Act of Congress concerning the energy policy of the United States. The stated purpose of the act is (quote) to move the United States toward greater energy independence and energy security, to increase the production of clean renewable fuels, to protect consumers, to increase the efficiency of products, buildings, and vehicles, to promote research on and deploy greenhouse gas capture and storage options, and to improve the energy performance of the Federal Government, and for other purposes (end quote). The Act originally sought to cut subsidies to the crude oil industry in order to promote crude oil independence and different forms of alternative energy. These tax changes were ultimately dropped after opposition in the Senate, and the final bill focused on automobile fuel economy, development of biofuels, and energy efficiency in public buildings and lighting. It was, and still is, felt by many observers that there should have been greater recognition of the role that natural gas can play in energy security.
