The Public Utility Regulatory Policies Act (PURPA, Pub.L. 95–617, 92 Stat. 3117, enacted November 9, 1978) is a United States Act passed as part of the National Energy Act. It was meant to promote energy conservation (reduce demand) and promote greater use of domestic energy and renewable energy (increase supply). The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis. Upon entering the White House, President Jimmy Carter made energy policy a top priority. The law started the energy industry on the road to restructuring.
