Jimmy Carter served as the 39th President of the United States from 1977 to 1981. He was awarded the 2002 Nobel Peace Prize for work to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development. Carter could point to a number of achievements in domestic affairs. He dealt with the energy shortage by establishing a national energy policy and by decontrolling domestic petroleum prices to stimulate production. He prompted Government efficiency through civil service reform and proceeded with deregulation of the trucking and airline industries. He sought to improve the environment. His expansion of the national park system included protection of 103 million acres of Alaskan lands. To increase human and social services, he created the Department of Education, bolstered the Social Security system, and appointed record numbers of women, blacks, and Hispanics to Government jobs.
