# Energy Energy consumption data is used to track the amount of energy used by a customer over a given time period.
The data can be used to identify energy-saving opportunities, monitor energy usage for sustainability initiatives, and track energy usage for billing purposes. ## The API endpoint retrieves electricity consumption - [GET /energy/electricity](https://docs.wia.io/apis/wia-rest-api/docs/energy/paths/~1energy~1electricity/get.md): The API endpoint retrieves electricity consumption data in kilowatt-hours (kWh) from electricity meters. The endpoint utilizes the underlying data from the meters to calculate and return the energy consumed by a customer during a given time period. To use the API endpoint, the user will need to provide the necessary information, such as the date range for which they wish to retrieve data, the device id or space id to which a group of devices belong, and any other relevant parameters. The endpoint will then gather underlying stores of meter readings and calculate the total energy consumed by the customer for a specified time resolution The energy consumption data will be returned in kWh, which is the standard unit of measurement for electricity consumption and the time units are in UTC. If the metres use current usage to read energy consumption, that is also outputted by the API endpoint with the same format as power consumption. This API endpoint can be useful for a variety of applications, such as tracking energy usage for billing purposes, identifying energy-saving opportunities, and monitoring energy usage for sustainability initiatives. ## The API endpoint retrieves Gas consumption data in - [GET /energy/gas](https://docs.wia.io/apis/wia-rest-api/docs/energy/paths/~1energy~1gas/get.md): The API endpoint retrieves Gas consumption data in (m³) from gas meters. The endpoint utilizes the underlying data from the meters to calculate and return the gas consumed by a customer during a given time period. To use the API endpoint, the user will need to provide the necessary information, such as the date range for which they wish to retrieve data, the device id or space id to which a group of devices belong, and any other relevant parameters. The endpoint will then gather underlying stores of meter readings and calculate the total gas consumed by the customer during the specified time period such as 15 minutes, 2 hours, 1 day etc. The gas consumption data will be returned in m³, which is the standard unit of measurement for gas consumption and the time units are in UTC. This API endpoint can be useful for a variety of applications, such as tracking gas usage for billing purposes, identifying consumption saving opportunities, and monitoring usage for sustainability initiatives. ## The API endpoint retrieves Water consumption data - [GET /energy/water](https://docs.wia.io/apis/wia-rest-api/docs/energy/paths/~1energy~1water/get.md): The API endpoint retrieves Water consumption data in (m³) from water meters. The endpoint utilizes the underlying data from the meters to calculate and return the water consumed by a customer during a given time period. To use the API endpoint, the user will need to provide the necessary information, such as the date range for which they wish to retrieve data, the device id or space id to which a group of devices belong, and any other relevant parameters. The endpoint will then gather underlying stores of meter readings and calculate the total water consumed by the customer during the specified time period such as 15 minutes, 2 hours, 1 day etc. The water consumption data will be returned in m³, which is the standard unit of measurement for water consumption and the time units are in UTC. This API endpoint can be useful for a variety of applications, such as tracking water usage for billing purposes, identifying consumption saving opportunities, and monitoring usage for sustainability initiatives.
