Question

American concept in public utility

Answer 1

Primarily, a public utility is whatever is defined as such by American statute law. The case for a concept of this kind cannot be adjudicated by economists. in this sense without being a public utility in law.

Public utilities provide water, electricity, natural gas, telephone service, and other essentials. Utilities may be publicly or privately owned, but most are operated as private businesses. Typically a public utility has a monopoly on the service it provides.
