Tips to save money on electricity
In fact, with electronics in general, unplugging after each use is the best solution to protect them. This avoids damage in case of abnormal voltage overload, as well as reducing the risk of fire and explosion in the home.
When you leave the appliance plugged in, whether it’s a washing machine or a TV, it will always be in a standby state, consuming power. And there are 4 types of electrical appliances that must be unplugged immediately after use, otherwise it will waste electricity and be dangerous.
Type 1: TV
When we watch TV, we rarely remember to unplug after use because it feels troublesome and time consuming. But doing so is very dangerous and costly.
A small experiment was done: Use a device to measure power consumption, then use the remote to turn off the TV. After about 10 minutes of shutdown, power consumption decreased from 200W to 1.8W. This number shows the power consumed by the TV when plugged in without turning on. With a power consumption of 1.8W, in 1 month of continuous plugging, the TV consumes 1.8 x 24 x 30 = 1,296Wh = 1.29kWh (electricity). With the current electricity price, we will lose about 5k/month, 150k/month when not unplugging the TV.
Type two: Charger
An author named Adrian Kingsley-Hughes from ZDNet did an experiment to study the amount of power consumed when keeping or unplugging the phone charger from the outlet. Adrian first used WhatsUp, which is a professional power meter to measure power consumption.
Then Andrian plugged an iPhone charger into an electrical outlet, keeping it there for a few days. The results show that a genuine Iphone charger consumes about 130Wh of power per month if not in use, and 1.5 kWh/year (nearly VND 3,000/year) for only 1 outlet.
For those who are wondering about the economy, the family uses many different chargers, you should consider unplugging immediately when not using the device.
Type three: Rice cooker
Leaving the rice cooker plugged in overnight in the warm mode is one of the ways to keep leftover rice from going stale and ready to eat the next morning. This is also one of the habits of the majority of Vietnamese housewives. And when the rice cooker is plugged in overnight, whether it’s in warming mode, incubating the pot or in any other mode, it also consumes power as usual.
For example, a rice cooker with a capacity of about 500W, plugged in for 2 hours, will consume 1KW of electricity per hour. 750W capacity uses 1.3 hours and consumes 1 KW of electricity per hour. If in rice cooking mode, the rice cooker only consumes about 600W – 1500W. However, when plugging in a genuine electric cooker overnight but leaving it in incubation mode, the power consumption will fall to about 40W – 150W.
From that, we can calculate, if you heat the rice overnight for about 10 hours, you will have to pay a cost of 0.4 to 1.5 electricity (equivalent to 4 thousand VND at peak hours) depending on to the capacity of the rice cooker. Calculate 1 month, you will save 120k electricity bill.
