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.

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.

3. Menu for Electricity Saving at Homes Agency for Natural Resources and Energy Let us check measures to be tackled at home and list “Electricity Saving Measures for My Home.” Electricity Saving Menu to be Tackled at Your Home Electricity Saving Effect Check Reduction Rate Electricity Consumption Reduced Always remember to set the room temperature to 28℃. ① 10％ 130Ｗ Air Conditioner * When the set temperature is raised 2℃. Use rattan blinds, reed screens and other shields to mitigate the sunlight through windows. (Electricity consumption by air-conditioners can be saved) ② 10％ 120Ｗ Turn the air-conditioner off and use an electric fan if at all possible. ③ 50％ 600Ｗ * Please note that dehumidification and frequently turning the air-conditioner on and off tend to increase power consumption. Refrigerator Change the temperature setting of your refrigerator from “High” to “Medium” and shorten the time the refrigerator door is opened. Do not place excess food inside the refrigerator. ④ 2％ 25Ｗ Lighting ⑤ Turn the lights off during the day and reduce lighting overnight to a minimum. 5％ 60Ｗ TV ⑥ Set it to the energy-saving mode. Reduce the brightness of the screen and turn the TV off when not in use. 2％ 25Ｗ * When the standard mode is switched to energy-saving mode and monitor operating hours are reduced to two thirds. ⑦ Use the OFF functions for toilet seat warming and for warm water supply and power saving function by a timer in case these functions are provided. Toilet seat with warm water spraying function By taking either action Less than 1% 5Ｗ ⑧ Unplug from the socket if these functions are not provided. Rice cooker Cook rice for one whole day using the timer function early in the morning and keep it in the refrigerator. ⑨ 2％ 25Ｗ Standby power Turn off electrical appliances at the plug rather than leaving them on standby (remote control off switch only). Pull the plug of electrical appliances not in use for long periods. ⑩ 2％ 25Ｗ Let us take actions on ④, ⑦, ⑧ and/or ⑩ also when we are not at home. ％ Ｗ Let us save electricity so that total reduction rates exceed 15%. ！ Let us save electricity within reason, by avoiding heat stroke caused by excessively limiting the use of air-conditioners. *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.

4. Menu for Electricity Saving at Homes Agency for Natural Resources and Energy Other Electricity Saving Options Check Air Conditioner Change the filter regularly (approx. once every two weeks) Refrigerator Hang a plastic sheet up in the refrigerator Heat water on the hob, pull the plug from the kettle 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 Make sure to plan ahead with your daily household schedule so you can avoid the daytime peak period of 9am through 8pm. Lifestyle 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. Be aware of water saving too: wash dishes together, reduce showering time, etc. Water Saving 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. *Values calculated are for guidance only. ○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.
