A Kilowatt-Hour Meter is a device used to measure the amount of electrical energy consumed by a residence, business, or electrical device. It records energy usage in kilowatt-hours (kWh), which is the standard unit for measuring electricity consumption. This information helps utility companies bill customers accurately based on their energy usage. These meters can be analog or digital, with digital versions often providing more detailed information, such as real-time usage and historical data. The readings from a Kilowatt-Hour Meter are essential for monitoring energy efficiency and managing electricity costs effectively.
