  •  ~Saving Electricity: Request for Your Cooperation ~
  • The power supply has been adversely affected by the Great East Japan Earthquake. The Agency for Natural Resources and Energy is requesting the assistance of households to reduce the total electricity usage by 15% during the peak period (9am-8pm, weekdays) during the summer months (July-September). Please read through this practical guide and make changes wherever you can to support the efforts to save energy.
  • When Should I Save Electricity?
  •  During the summer months (July-September), demand for air conditioning (and the electricity required to power it) rises. 2pm represents the peak period for energy demand, including ordinary households.
  • We are asking householders to be mindful of the need to save energy throughout the day, and to focus particularly on the peak period of 9am through 8pm.

  • Saving Electricity: The Basics
  • What electrical appliances are you using?
  • At 2pm on an average summer day, the average household consumes 1200W of electricity. Air conditioners account for around half of this total.
  • Even in those households where nobody is at home during the day, standby electricity consumption from refrigerators, Toilet seat with warm water spraying functions, and other appliances still results in an average electricity consumption of around 340W.
  • Electricity Consumption by Main Household Electrical Appliances
  • 【Electricity consumption on a summer day (2pm, average for all households)
  • *Rated electricity consumption levels are examples only. Actual electricity consumption will depend on product model and usage conditions.
  • 【Rated Electricity Consumption Levels for Main Household Electrical Appliances
  • Source: Agency for Natural Resources and Energy statistics
  • Numerical values for day representing record (highest recorded) demand
  • Your household is likely to contain multiple appliances using more than 1,000W of electricity. Please try to avoid using electrical appliances that consume large amounts of electricity during the peak period of 9am through 8pm on weekdays.

  • * Please note that dehumidification and frequently turning the air-conditioner on and off tend to increase power consumption.

  • Lifestyle
  • Structure your housework schedule around your electricity saving plan
  • The level of electricity consumed when the household is empty is much lower than that consumed when people are at home. Holidays and going out are an important way of saving electricity, too.
  • Make sure to plan ahead with your daily household schedule so you can avoid the daytime peak period of 9am through 8pm.

  • Change the filter regularly (approx. once every two weeks)

  • ○Find Out About the Electricity Consumption Levels of Your Electrical Appliances
  • Take the time to find out about the electrical appliances that you use in your home. Read instruction manuals or take a look at the appliances themselves, you should be able to find annual electricity consumption levels and rated consumption levels indicated on main units.
  • Take a moment to work out the approximate electricity consumed by the electrical appliances in your own home during summer.
  • ○Upgrade to Low Energy Models
  • Another way you can contribute to the electricity saving efforts is to replace older appliances with the latest low-energy and energy-saving models. The ‘Uniform Energy-Saving Label’ is a label providing information on electricity saving effects which you can refer to when looking to buy new appliances. (You should be aware that purchasing models that are larger than your current appliances may result in increased electricity consumption levels).
  • ○Swap Incandescent Light Bulbs for Self-Ballasted Fluorescent Lamps and LED Bulbs
  • A single incandescent light bulb (equivalent to 60W: 54W) can consumer as much electricity as a latest 32V LCD television model.
  • Swapping incandescent light bulbs for self-ballasted fluorescent lamps (12W) can immediately save around 42W, swapping them for LED lamps (8W) can immediately save around 46W.
