2. Electric Fan
In the Autumn-Winter season, the demand for air conditioning and cooling fans decreases in the Northern provinces. However, even when not in use, these devices still consume a small amount of electricity. Therefore, users should regularly clean the fan blades and external parts. If the fan is turned on, it should be set to a moderate speed. After use, unplug the fan from the power outlet. Additionally, consider using ceiling fans instead of air conditioning, even on hot days, as they provide significant airflow and lower electricity costs.
When using devices such as computers, laptops, and TVs, users should adjust the screen brightness to a moderate level. Choose power-saving modes to save electricity and protect the devices. Furthermore, when turning off the TV, avoid using the remote and instead turn it off by pressing the power button or unplugging it for computers and laptops.
For modern households, the washing machine is an indispensable appliance. However, operating a washing machine consumes a considerable amount of electricity and water. Therefore, if you want to save energy, only use the washing machine when you have enough clothes to wash. If there are few clothes, you can wait or consider handwashing to save electricity and water.
Avoid cooking rice too early in the electric rice cooker. Only cook rice 30 to 45 minutes before eating to reduce reheating time. Additionally, remember to turn off the rice cooker after use to avoid maintaining the warm mode unnecessarily, which wastes electricity and serves no purpose. Users should also clean the bottom of the rice cooker and the heat plate to ensure better electrical contact and prevent energy waste.
Similar to cooking rice, only turn on the water heater 30 to 45 minutes before bathing. Also, adjust the temperature level of the water heater according to usage needs. Do not set it too high to avoid waste. It's also advisable to coordinate bathing times with family members to save electricity. After use, immediately turn it off. For families with infants or small children who need hot water constantly, consider using thermal pots, water boilers, or adjust the water heater to a low setting for continuous use throughout the day.
According to the U.S. Department of Energy, LED lights save about 75% energy and have a lifespan about 25 times longer than traditional incandescent bulbs. Therefore, to conserve electricity and illuminate more efficiently, users should switch to LED lights instead of incandescent or traditional neon bulbs.
Nowadays, with the emergence of smart-home models, smart lighting solutions using motion sensor detection are increasingly being adopted by Vietnamese households in apartments and condos. The mechanism of these devices is to only turn on the lights when motion is detected in the room, so they can be effectively used in hallways, entryways, bathrooms, kitchens, etc. A statistic from the U.S. Department of Energy states that using motion sensor devices can cut down on wasted electricity by up to 30%.
