Typical US domestic electricity meters
An electric meter or energy meter is a device that measures the amount of electrical energy supplied to or produced by a residence, business or machine.
The most common type is more properly known as a kilowatt hour meter or a joule meter. When used in electricity retailing, the Utilities record the values measured by these meters to generate an invoice for the electricity. They may also record other variables including the time when the electricity was used.
