The Public Utility Regulatory Policies Act is a United States Act passed as part of the National Energy Act.
It was meant to promote energy conservation and promote greater use of domestic energy and renewable energy.
The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis.

The Railways Act 1921, also known as the Grouping Act, was an Act of Parliament enacted by the British government and intended to stem the losses being made by many of the country's 120 railway companies, by grouping them into four large companies dubbed the Big Four.
This was intended to move the railways away from internal competition, and retain some of the benefits which the country had derived from a government-controlled railway during and after the Great War of 1914–1918.
The provisions of the Act took effect from the start of 1923.
