1. Does a Microwave Oven Consume Electricity?
Microwave Oven Power Rating
To answer the question of whether a microwave oven consumes electricity, you need to know its power rating. The power rating is usually indicated on the microwave or in the user manual. Typically, microwave ovens have power ratings ranging from 600W to 2200W.
Microwaves with average power ratings between 600W and 1100W are often budget-friendly, mid-sized models with a capacity of around 20-25 liters. High-power microwaves, ranging from 1100W to 2200W, fall into the premium segment with larger oven capacities of 25 liters and above.
Does a Microwave Oven Consume Much Electricity?
Notably, microwave ovens boast a relatively high power, averaging around 1000W; the time required for heating or thawing food in a microwave is typically about 2 minutes. Consequently, the energy consumption of a microwave is approximately: 1000W x 2/60 = 33.33W. This power consumption is equivalent to running an electric fan continuously for 1 hour.
If you use a microwave to cook a meal for about 20 minutes, the energy consumption will be: 1000 x 20/60 = 333.33W.
At an electricity rate of approximately 2500 dong/kWh, heating or thawing food will cost around 0.033 kWh (0.033 x 2500) = 82 dong. Similarly, the amount you have to pay to cook a meal with a microwave will be 820 dong.
So, does a microwave consume a lot of electricity? Due to its high power, microwaves can be relatively power-hungry. However, since you only use the microwave for heating or thawing for about 2-3 minutes, the energy consumption is negligible.
2. Tips for Efficient Microwave Usage
Use a microwave with power suitable for your needs
Higher wattage implies higher electricity consumption. When purchasing a microwave, choose one with power that suits your family's usage needs.
For larger families frequently preparing meals with a microwave, opt for a higher-power microwave to meet the demand. For smaller households using the microwave mainly for heating or thawing, a microwave with power in the range of 600W – 1000W is sufficient.
Properly heat or thaw food
When heating or thawing food, don't immediately remove it when the microwave signals the end of the process. Instead, leave it in the microwave for an additional 2 – 3 minutes to evenly distribute heat throughout the food. This reduces cooking time and saves energy consumption.
Organize your food
Microwaves cook food based on electromagnetic waves, but the distribution is uneven, resulting in some areas being hotter than others. Especially, food placed in the middle of the microwave takes longer to cook than those around the edges.
Arrange food in a circular pattern when placing it in the microwave to allow even heat distribution, ensuring uniform cooking and significant energy savings.
Limit continuous door opening
Continuously opening the door or not sealing it tightly allows hot air to escape, forcing the microwave to increase power and operate continuously, wasting electricity.
Moreover, an improperly sealed door allows electromagnetic waves to spread outside, adversely affecting the health of users.
Unplug after use
After using the microwave, remember to unplug it. Since the microwave is always in standby mode without a power-off button, leaving it plugged in when not in use poses safety risks and wastes energy.
Upgrade Your Microwave
Old microwaves may prolong heating times, leading to increased energy consumption. If your home appliance is too old, consider upgrading to a new microwave from reputable brands like Roler, Samsung, Panasonic,... for safe and energy-efficient use.
