This research paper briefly reviews the historical background of the United Sates domestic energy policy and lists all the energy policies enacted from the 1920s to 2009. It then goes on to review some of the methods and instances of interest groups and lobbyists influencing public policy making and even the legislative processes of those policies. The paper proceeds from there by reviewing and analyzing secondary data by investigative reporters from reputable newspapers like the The New York Times, The Washington Post and This Week Magazine on the Energy Policy Act of 2005. The preponderance of evidence presented in those reports clearly points to the fact that the oil and gas industry actually influenced the recommendations rendered by the national energy task force which was headed by the former Vice President, Dick Cheney. However, readers of this paper are free to make their own judgment after reading the evidence presented and the conclusion drawn from a study in Roger H. Davidson et al work titled Congress and Its Members.
