* '''[[electric power]]''' (which can refer imprecisely to a quantity of [[electrical potential energy]] or else more correctly to electrical [[power (physics)|energy per time]]) that is provided commercially, by the [[electrical power industry]]. In a loose but common use of the term, "electricity" may be used to mean "wired for electricity" which means a working [[electrical connection|connection]] to an electric [[power station]]. Such a connection grants the user of "electricity" access to the [[electric field]] present in [[electrical wiring]], and thus to electric power.

Multiple lightning strikes on a city at night
Lightning is one of the most dramatic effects of electricity.

Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is the backbone of modern industrial society, and is expected to remain so for the foreseeable future.[1]

The word electricity is from the New Latin ēlectricus, "amber-like"[a], coined in the year 1600 from the Greek ήλεκτρον (electron) meaning amber, because electrical effects were produced classically by rubbing amber.
