【简答题】Translate the passage into English, using the theories you have learned as guidelines. Laws and regulations involving the production and distribution of energy resources have existed for well over one hundred years in the U.S.. Until the 1970s, these laws focused on economic regulation. The dominant model of energy law was regulation of public utility industries made up of companies that served a public interest, such as electric and gas companies. The central question during this time was whether companies that produced and distributed energy resources should operate with government oversight to ensure that they served the public interest, or whether they should be allowed to operate in an unregulated market. Economists believed that some regulation of public utilities was necessary because most energy industries can have natural monopolies, where a single company can exploit the energy resource at a lower average cost than two or more companies. There is a substantial body of literature on the economic case for regulating natural monopolies. Public utility regulation took place mostly at the state level, where administrative agencies known as public utility commissions (PUCs) regulated energy companies’ rates and services. Regulation was designed to guard against monopolistic abuses. A second historical component of U.S. energy law is natural resources laws that govern the granting and regulation of rights to produce minerals and other natural resources in the U.S. and abroad. For example, a web of state and federal laws governs the structure of leases for the extraction of oil and gas. The laws relating to production of individual energy resources are often the subjects of focused study in the law school curriculum. A school may offer a course in Oil and Gas Law, or one in Mining Law, for example.
