Electric Rice Cooker
A common household appliance used daily, many homemakers often turn on the rice cooker hours before mealtime due to time constraints.
This seemingly simple act can lead to significant electricity consumption, even more so than air conditioners. The longer the cooker is plugged in, the more energy is required to keep the rice warm, potentially leading to wasteful energy usage.
A typical 1.2-liter electric rice cooker has a power rating of 350-400W. If left on for two hours, such a cooker will consume approximately 0.75 kWh. Larger rice cookers will, of course, consume even more energy.
Phone Charger
Many people leave their phone chargers plugged into the wall socket even when not in use. What they may not realize is that these chargers continue to draw power, even when not connected to a phone. While the amount of electricity consumed is relatively small, at around 1.2W, it can add up over time if the charger is constantly plugged in, contributing to higher electricity bills each month.
Refrigerator
One of the biggest energy consumers in the home, refrigerators run continuously and therefore, despite their relatively modest power ratings, can contribute significantly to electricity bills.
A small 150-liter refrigerator with a power rating of 100-150W can consume up to 5 kWh of electricity per day. Larger refrigerators with higher power ratings will, of course, consume even more energy, with some using up to 6 kWh per day. This is a significant amount of power for a single household appliance.
Frequent opening and closing of the refrigerator door throughout the day also cause the machine to work harder, leading to a spike in electricity consumption.
Electric Rice Cooker (continued)
As mentioned earlier, the electric rice cooker is a ubiquitous appliance in many homes and is used daily. Due to time constraints, some homemakers may leave the rice cooker on for extended periods, believing it to be a convenient solution.
However, this practice can lead to excessive energy consumption, even surpassing that of air conditioners. The longer the cooker remains plugged in, the more energy is required to keep the rice warm, resulting in potential energy wastage.
A 1.2-liter electric rice cooker typically has a power rating of 350-400W. If left on for two hours, it will consume approximately 0.75 kWh. Larger rice cookers will, of course, consume a greater amount of energy.
Television
A staple in most households, televisions are often perceived as having a minimal impact on electricity bills due to their relatively small power ratings. However, this is not always the case.
A 32-inch television, for example, typically has a power rating of 40W. If left on continuously, it can consume a significant amount of electricity. Additionally, the heat generated by the TV also contributes to energy wastage. Even when turned off but still plugged in, a TV can cost a household up to 500,000 VND per year in electricity costs.
Digital TV Signal Receiver
This device often goes unnoticed, and most people only turn off the TV without paying attention to it. According to Bright Side, this device can cost up to 22 USD per year in electricity bills if left on continuously.
