Starting today (1st), the "summer price" will be implemented until September. According to Taiwan's power data, the average family's summer phone fee is estimated to be 440 yuan more than the summer month. Many people are starting to suffer and have to tighten their bags. Various power-saving myths and rumors are also being circulated on the Internet, but what is the truth?

Taiwan Electric said that "turning the lights can save electricity by hand", "washing laundry in the middle of the night is really more efficient", and "saving electricity to save lights" … are the most concerned and further inquired by the public in recent days.

But can "turn off the lights with your hands save power"? Taiwan Electric pointed out that as for general appliance products, the switch lights on the lights must be effective in relieving energy, but the usage characteristics of the appliance products must still be considered. For example, the general sunlight frequency switch is switched, although the power costs are saved, the life of the lamp tube is reduced and the cost of changing the lamp tube is increased.

Is it true that "washing laundry in the middle of the night is really more efficient"? Taiwan Electric pointed out that if users apply for electricity prices, they can transfer the power consumption of peak hours to peak hours for use, which can actually reduce the electricity fee. As for users who do not apply for a time-to-electricity price, they cannot get cheaper electricity prices even when washing clothes or using electricity during peak hours at night.

Taiwan Electric said that many people will also change power-saving light bubbles in order to save electricity, but is "power-saving light bubbles the most power-saving"? Taiwan Telecom said that the power saving effect mainly depends on "luminescence efficiency". The higher the luminescence efficiency, the more power saving it is. The luminous efficiency of LED light bubbles is 70~110 lumens per watt, the power-saving light bubbles are 50~80 lumens, and the white light bubbles are 10~20 lumens.
