This concept designed based on a scenario of sustainable life in 2020. The green line, inspired by leaf as the symbol of green life, indicates how much energy user is using and it turns into orange and red once the energy usage reaches to caution and critical level.

The concept is supported by a proposed system called Active Consumption Meter which gathers information from all the home appliances via Bluetooth technology and calculates the energy of the house as the fridge can play an important role to notify users about theusage of electricity and energy.
