I-3. Transition of Energy Consumption in the Commercial/Residential Sector

Transition of Energy Consumption for Home Appliances

Refrigerators, lighting and televisions account for a large portion of electricity consumption in the residential sector.
Consumption for new equipment, such as toilets with "warm-water washlet" and dishwashers/dryers, has increased, although the percentage in total electricity consumption is not large at present.

I. - 3. Transition of Energy Consumption in the Commercial/Residential Sector Trend in Standby Power Consumption
Standby power consumed by households accounts for approximately 7% of total household power consumption (almost equivalent to half the annual power consumption of a refrigerator used by an average household).

* Standby Power Consumption: Power consumed while electrical appliances are not in use (Power consumed by the timer function, remote controller receiver, etc.)

I. - 3. Transition of Energy Consumption in the Commercial/Residential Sector

Transition of Floor Space by Type of Business in the Commercial Sector

Energy consumption in the commercial sector increases with an increase in total floor area of offices, business buildings, etc.
(Floor area and energy consumption increased by 2.2% and 1.6% on an annual average, respectively.)
