"The Public Utility Regulatory Policy Act (PURPA) was passed by Congress in 1978, went through a series of legal challenges, and finally became law in 1982. Congress originally envisioned the law as a way to encourage small, independent companies... to develop alternative fuels and other innovative approaches to producing electricity. Under this law, the major utility companies were required to purchase energy generated by the smaller companies, at fair and reasonable prices. This policy was a result of Carter's desire to reduce U.S. dependence on oil —all oil, not just imported oil. The intent of the law was clearly to encourage both alternative energy sources and the development of independent companies that reflected America's entrepreneurial spirit. However, the reality turned out to be something very different."
