A regulatory commission or agency is an organization created by the government with the purpose of enforcing specific regulations on a certain part of the economy. The United States was the first country to create this type of agency.
The U.S. created the Interstate Commerce Commission in 1887. Although this agency was disbanded in 1996, it was established to oversee the railroads. The agency was expanded to other types of travel as they developed, and it was the forerunner of other commissions like it.
The United States still has many of these types of agencies, including the Federal Energy Regulatory Commission and the U.S. Nuclear Regulatory Commission. The purpose of the Federal Energy Regulatory Commission is to provide standards for all forms of energy used in the U.S., such as gas, oil, natural gas, electricity and water power. It seeks to make energy costs affordable for consumers but also to make sure the extraction and transportation of energy resources is done in a safe and responsible manner.
The U.S. Nuclear Regulatory Commission oversees any use of nuclear material, from power to medicine. Its main purpose is to enforce safety codes so that nuclear material does not harm humans or plant and animal life in the U.S.
