A comprehensive energy statute comprised of five separate but intertwined public laws dealing with energy conservation (The National Energy Conservation Policy Act, P.L. 95-619); coal conversion (The Powerplant and Industrial Fuel Use Act, P.L. 95-620); public utility rates (The Public Utility Regulatory Policy Act, P.L. 95-617); natural gas pricing (The Natural Gas Policy Act, P.L. 95-621); and a series of taxes (Energy Tax Act, P.L. 95-618) designed to discourage energy consumption and to accelerate the transition to alternative fuels. The five bills were signed into law on November 9, 1978. The main purpose of the NEA is to reduce oil imports and promote more efficient use of energy in this country.
