Energy metering is the process of measuring the amount of energy consumed by a building, appliance, or system. This is typically done using devices called energy meters, which track electricity, gas, or water usage. These meters provide valuable data that helps consumers understand their energy consumption patterns and manage their utility costs effectively. Accurate energy metering is essential for both residential and commercial settings. It enables utility companies to bill customers based on actual usage rather than estimates. Additionally, energy metering supports energy efficiency initiatives by identifying areas where consumption can be reduced, ultimately contributing to sustainability efforts.
