What term describes the provision of electrical power to households and businesses?

The term that best describes the provision of electrical power to households and businesses is "Electricity supply." This term specifically refers to the system of generating, transmitting, and delivering electricity to end users, which includes both residential and commercial sectors. It encompasses the entire process from energy generation at power plants to the distribution lines that deliver that energy to consumers.

"Power distribution" refers more specifically to the process of delivering electricity from substations to consumers, whereas "Energy provision" is a broader term that can include various forms of energy, not just electricity. "Utility service" can refer to a range of services provided by a utility company, which may include electricity, water, gas, and telecommunications, making it less specific than "Electricity supply." Thus, the choice of "Electricity supply" correctly encapsulates the provision of electrical power to households and businesses.
