If you have tried to prepare rice, you should know that sometimes it can be a bit complicated. You need to be rather careful not to burn your meal or sometimes prepared rice can turn out to be too sticky which is also unlikeable.
For those who cook rice often and don’t want to make a lot of effort, a typical rice cooker is a great option since it helps to make the cooking process much easier. On the other hand, people are worried about the energy efficiency of this device. It is not only about money. People wonder whether this electric appliance is eco-friendly or not.
A rice cooker can be a great option for both single people and large families since it is easy and convenient to use. However, you need to know some nuances before buying one because using the wrong type of rice cooker will only increase your electricity bills, which is not favorable.
So if you are interested in how much energy a typical rice cooker consumes and what factors influence this and how to choose the right rice cooker, keep reading.
The energy efficiency of a rice cooker compare to other electrical appliances
Even though rice cookers consume more energy than other appliances, they are still more energy efficient. Why? Rice cookers prepare food evenly without any heat loss. You may see your energy bill rise after using an electric rice cooker, but it is still considered to be a great device since it optimizes the cooking process and saves you a lot of time.
If you take advantage of a rice cooker, all you need to do is measure the right amount of products, fill in the pot and leave till the special timer automatically turns off the device when the meal is prepared. In addition, using a rice cooker helps you to avoid cooking a sticky rise. But you need to know how to select the appropriate type of rice cooker based on your requirements.
How many watts does a rice cooker use? How much does it cost per use?
Generally, three main factors determine how much energy your rice cooker requires for the cooking process. The energy consumption depends mainly on the model of a rice cooker, its size, and frequency of usage. Approximately it is 0.5 kW of energy per hour will cost you 0.048 cents per usage.
Moreover, you should take into account that cooking brown rice will require an extra $0.36 per usage in comparison with white rice. Also, your rice cooker can require more or less energy based on the cooking mode you use. Cook mode requires 500 to 1000 watts per usage, while warm mode needs 30 to 50 watts.
You should also consider that energy usage will depend on the amount of water you use for making rice. 180 ml of water will require 150–200 watts, and 80 ounces (about four liters) will need about 600 watts. You can always adjust the size of your pot but remember that with a lower wattage, the preparation time rises, which also is not very beneficial.
How many watts does a rice cooker use? Calculate more accurately
Many users prefer to know the exact amount of energy their device spends per usage.
To start with, if you want to find out the more accurate power consumption of your device, you need to figure out how much power your electric rice cooker has.
Now there are two ways to find out how much electricity your electrical appliance uses.
Check the data from the label
You need to add together the wattage and multiply this by how long it takes for one cup of rice to be prepared. Now divide the number you’ve got by 1000 (watts per kilowatt-hour) and multiply it by the number of cups you have used. The number you’ve got means the cost per every cup of rice cooked per hour.
Take advantage of a measuring device
Another way to calculate the power consumption is to use a measuring device. Just insert the device into the outlet and then connect it to the rice cooker. If you are using a measuring device, you are likely to have more accurate numbers.
Compare rice cookers to other cooking appliances. How to choose an energy-efficient rice cooker?
If we have a deeper look at a rice cooker and a stovetop we may notice that electricity consumption for a rice cooker is 0.5 units per hour and 3 units per hour for a stovetop. In addition, selecting a rice cooker is likely to save money by reducing the electricity bill.
You can buy a multicooker, which is capable of cooking any type of meal and will definitely save electricity and money.
However, sometimes it is more effective to use both a stovetop and an electric cooker. For example, you may cook rice on the stovetop while setting a timer for your electric cooker. It will automatically turn off when the rice is prepared, which is a good example of effective time management.
If you’ve decided to buy a rice cooker, don’t take the cheapest one. The price of a basic model usually varies from $25 to $400. Take into account how much power the electric cooker uses. Consider the size of the pot and wattage. These two features will mainly influence power consumption.
An electric rice cooker can always be adjusted to consume less electricity by turning it on to a low setting; however, it will take you more time to prepare the meal. Also, take advantage of a timer that automatically turns the device off when the meal is prepared.
The power consumption of a rice cooker may vary from 500 watts to 1000 watts. This difference is due to some design features, bowl volume, and available modes. Choosing a low-power rice cooker is not a solution, since it will spend more time for cooking rice, which directly increases your energy bills.
So, we recommend choosing the convenient rice cooker, which has reasonable power and pot volume (you don’t need the most powerful rice cooker if you don’t have a large family), and also additional features, like sleep mode or a steam basket, which will be favorable for you.
Do rice cookers consume less electricity in a warm mode?
As we have already mentioned, the power consumption of a cook mode varies from 500 to 1000 watts, while warm mode requires 30 to 50 watts. So, we may say that most rice cookers require more electricity for a cooking mode and less for a warm mode. However, it all depends on the model of your device.
Modern models have complex circuit mechanisms. Those new rice cookers also have a sleep mode, which reduces electricity consumption. Basic electric cookers are equipped with a simple circuit mechanism. That is why both cook mode and warm mode need the same quantity of energy.
Does the power consumption of a rice cooker depend on the amount of rice? How long can I leave my rice cooker in a warm setting?
It is not directly influenced by the amount of rice. Here, cooking time matters. The more rice you want to cook, the more water you use and the more time you require. Therefore, the consumption of power increases. Moreover, not only the amount of rice but also the type of rice influence the cooking process.
Brown rice requires more time and energy, which leads to a wattage increase of 80 watts, while the same electric appliance doesn’t need the same amount of power to prepare white rice. What concerns fluffy rice, all the water from the rice cooker must be dried, which increases cooking time and therefore energy consumption.
In case you cook rice for a long while, you not only spend more energy but also ruin its quality.
That is why many people never use warm mode. Leaving the device in a warm setting for a while won’t significantly damage your bills, but leaving the rice inside the electric cooker is not sanitary, since the number of bacteria will increase with enormous speed.
How to cook rice without extra energy loss?
As you may see, rice cookers can be rather efficient, but only in case you know how to use them properly. That is why many users wonder how should they use their devices to save time and energy instead of wasting them.
First of all, pot volume is important to consider. Basically, rice cookers are designed for specific amounts of rice which are not to be increased, and cooking less rice is also not advisable. That is why also take this characteristic into consideration before buying a device. If you have a big family, you require a larger pot of rice cooker and vice versa.
In addition, you should always get acquainted with the appliance manual (or at least ask a shop assistant before buying a rice cooker). It contains the necessary information about cooking modes, additional features, the device’s capacity, and so on. It will help you optimize the process, save energy and money, and prolong the lifespan of your rice cooker.
How many watts does a mini rice cooker use? – The quantity may vary depending on the amount of rice and the mode you use since warm mode usually requires less power. Basically, a mini rice cooker (for example Dash mini rice cooker) uses 200 watts with a $0.014 cost per use.
How many watts is a 3-cup rice cooker? – In general, a 3-cup rice cooker uses 200 watts.
How many amps does a rice cooker draw? – This number may vary depending on the model of your device. For example, the Zojirushi NS-TSC10 5 1/2 cup rice cooker requires 5 amps (610 watts divided by 120 volts).
How many watts is a 10-cup rice cooker? – Such rice cookers will require approximately 700 watts.
To draw a conclusion. Is a rice cooker an energy-efficient device or not?
If we compare a basic rice cooker with other appliances you may have in your kitchen, we may say that purchasing a rice cooker can be a great decision if you want to save time and optimize the process. Rice cookers are more energy efficient than simple stovetops, but it is only in case you use your device properly.
Power consumption depends on many factors. First of all, you need to take into account the power and capacity of your device. The higher wattage is, the faster the cooking time, and the less electricity is consumed. And the volume of 0.5 to 0.8 L will be enough to cook rice for a single person, and a 1 to 3 liters volume is suitable for big families.
The energy consumption also depends on the mode and type of rice you use.
Warm mode is considered to be more efficient since it needs fewer watts for an hour of the cooking process, but it is not completely true, since it takes much more time to cook rice in this mode. What concerns the type of rice, white rice requires less power to be cooked.
So rice cookers won’t significantly reduce your energy bills, but they are very convenient and easy to use since you can just measure the right of rice, fill in the pot, turn it on and then mind your business till the rice is cooked. And the special timer will automatically switch off your rice cooker when a meal is prepared.
You can cook different kinds of meals in your electric cooker and take advantage of it while cooking for a large company (for example a family gathering). So if you are cooking rice often, this device is a great option for you. Make sure you got acquainted with the appliance manual to figure out all the information you need to know for better performance of your rice cooker.
