# What is kWh

A kilowatt-hour (kWh) is a unit of energy used to measure electricity consumption or production. It represents the amount of energy consumed when 1 kilowatt (1,000 watts) of power is used continuously for 1 hour.For example:

* If you run a 100-watt light bulb for 10 hours, it consumes 1 kWh (100 watts × 10 hours = 1,000 watt-hours = 1 kWh).
* Similarly, if a 2 kW appliance runs for 3 hours, it uses 6 kWh of energy.

This unit is commonly used in electricity bills to show how much energy you have used over a billing period.

Arkreen Network issues the ERC-20 token KWH by burning ART (1 ART -> 1000 KWH) in a one-way behavior. This eliminates the overhead of maintaining the bi-directional mapping of ART and AREC and thus, lowers the gas fee. KWH, standing for Kilo-Watt Hour, is used on Arkreen Network as a lightweight green asset for all greening activities.
