Saving electricity at home reduces CO2 emissions!



Electric cars, all-electric houses, etc.
"Electricity" has an image of being good for the environment, but in fact, more than 40% of CO2 emissions in Japan are caused by thermal power generation!
It is very important for each and every citizen to save electricity!




1) Reduces standby power

"Standby power" refers to the power consumed just by being plugged in even when not in use. Let's reduce power consumption by turning off the switch or unplugging from the outlet when not in use!



"Let's use power-saving taps!"


Convenient power-saving tap! The individual switches make it easy to turn the power on and off! Turning the power off and on is the same as unplugging it, so you can reduce power consumption!





If all standby power for home appliances could be reduced

Annual savings of approximately 6,500 yen, 285 kWh*1, and a

CO2 emissions reduction of 117.7 kg*2

(Calculated using the CO2 emission coefficient for electricity of 0.413 kg-CO2/kWh.

Calculated at 22.86 yen/kWh) - Calculated in Japan




2) Let's get creative with the air conditioner temperature settings!

According to the website of the Ministry of the Environment in Japan, a 1 degree Celsius increase in air-conditioning in summer can reduce power consumption by about 13%.

In winter, lowering the heating temperature by 1 degree Celsius reduces power consumption by about 10%!



"Clean the filter often!"


Cleaning the filter increases the efficiency of the air conditioner and saves 0.6% to 1.9% of electricity!

After cleaning the filter, the amount of electricity consumed is reduced by about 7% compared to before cleaning! Cleaning is important for both saving money and power!



Air conditioners tend to use the most electricity when they are turned on (at startup). If the air conditioner is repeatedly turned on and off every time you go in and out of a room, the power consumption will increase by that much.


Out for 30 minutes to 1 hour: Leave the air conditioner on.

Out for more than a few hours: It is better to turn off the air conditioner.




3) Great power saving by devising home appliances!

Refrigerators are the No. 1 annual power consumer among home appliances! TVs, etc., which consume a lot of standby power. If used correctly, a 20% cut in power consumption is not just a dream!



"Temperature setting on refrigerator."


Many people think that the temperature should be set to "high" in the summer and "low" in the winter, but if used correctly, "medium" is fine throughout the year! "Medium" is the most suitable temperature for refrigerators, freezers, and vegetable compartments.





Use Your Refrigerator Right and Save! Save electricity!

(1) Minimize door opening and closing (2) Do not overfill with food

(3) Allow hot food to cool down before storing it (4) Leave space between installation and surrounding walls and objects

(5) Avoid installing in places where it gets hot.




"Let's turn off the main power to the TV!"


Note that televisions consume a certain amount of power when the main power is on! Therefore, if you will not be using the TV for a while because you will be traveling or going out, you can reduce power consumption by turning off the main power. Adjusting the brightness of the screen will also help save power!




"Less laundry!"


Use the washing machine as little as possible! Wash clothes in batches after a certain amount of laundry has accumulated! If you are thinking of replacing your washing machine, you may want to choose a washing machine with an energy saving mode!





4) LED bulbs!

Save 94 kWh or about 2,500 yen per year just by replacing incandescent bulbs with LED bulbs! (2,000 hours of lighting per year / 27 yen/kWh calculation)



"Let's use LED bulbs!"


They say switching to LED lighting is one of the most efficient energy-saving measures you can take! They consume less power and last longer! Incandescent bulbs need to be replaced in a few months and fluorescent bulbs in a few years, but LEDs need to be replaced in 8 to 10 years!




5) Get your home's electricity to renewable energy!

Switch your home's electricity to environmentally friendly renewable energy! Renewable energy (renewable energy) refers to electricity produced by solar, wind, hydro, geothermal, biomass, and other power generation methods. The biggest advantage is that CO2 emissions are reduced. Solar power and wind power generate almost no CO2 when generating electricity.
