Menu for Electricity Saving at Homes
~ 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 What electrical appliances are you using?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.

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.

Agency for Natural Resources and Energy. Fractions below the decimal point in the reduction rates are ignored.
Turn the air-conditioner off and use an electric fan if at all possible.
Use rattan blinds, reed screens and other shields to mitigate the sunlight through windows. (Electricity consumption by air-conditioners can be saved)

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.
Remember that holidays and going out in the daytime help save energy too
Make sure to plan ahead with your daily household schedule so you can avoid the daytime peak period of 9am through 8pm.
