~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.

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.
Toilet seat with warm water spraying function, kettles, dishwasher dryers, oven toasters,
vacuum cleaners, dryers, washing machines and tumble dryers, bathroom dryers, rice coockers,
microwaves, irons, IH cooking heaters, etc.

*Values listed above as effects of electricity saving are a guide for reduction rates and power consumption reduced
based on average daily power consumption of an occupied household (14 hours, about 1200W) as estimated by the
Agency for Natural Resources and Energy. Fractions below the decimal point in the reduction rates are ignored.

Other Electricity Saving Options
Air Conditioner
Change the filter regularly (approx. once every two weeks)
Refrigerator
Hang a plastic sheet up in the refrigerator
Kettle
Heat water on the hob, pull the plug from the kettle
Washing Machine
Make sure the drum is always at least 80% full
Personal Computer
During the daytime, where possible pull the plug of notebook computers and use on battery only
Vacuum Cleaner
Replace internal paper bags regularly
Structure your housework schedule around your electricity saving plan
Lifestyle
Make sure to plan ahead with your daily household schedule so you can avoid the daytime peak period of
9am through 8pm.
Remember that holidays and going out in the daytime help save energy too
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.
Water Saving
Be aware of water saving too: wash dishes together, reduce showering time, etc.
Saving water means reducing the level of electricity consumer by water pumps and water and sewerage systems.
Getting Ready for Summer
○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.
