How much electricity does a microwave use? This is the first question you will ask when you want to purchase one. For this question to be answered suitably, we need to understand how a microwave operates and the energy it consumes.
A microwave has become a popular appliance in our kitchens. This gadget uses microwave radiation to reheat food. Other more advanced models can cook and bake. Since it is quite handy, it also consumes a lot of electricity. Therefore, it is important to know how much energy an average home microwave oven uses so that you can control electricity bills.
How Many Watts Does a Microwave Use?
Microwaves energy consumption is measured in watts. Average microwave wattage depends on how often it is used, energy efficiency rating, and the model. It is possible to categorize microwaves based on their energy consumption as follows:
1. Compact Microwave

This microwave is small and uses little electricity compared to the rest. It is mainly found in hotel rooms, student accommodations, or small households. It uses 600-800 watts. This is the best microwave to save energy and lower your electricity bills. However, the power levels for compact microwaves are quite lower. The appliance takes a long time when cooking food.
2. Standard Microwave

It is large and has powerful settings. This type of microwave has the highest energy consumption and the lowest cooking time. It is used in restaurants, hospitals, and high-end hotels because it allows large amounts of food to be heated at a go.
Commercial microwaves use over 1,000 watts. It also allows for power settings to be put in place so that you save electricity without utilizing full power.
How Much Does it Cost To Run a Microwave?

To determine the cost of running your microwave, you have to do some math. The steps below will guide you on how to estimate the total cost.
i) Determine the wattage of your microwave oven. This you can find on a sticker at the back of your gadget. It is also known as the power rating.
ii) Use the wattage to calculate the kilowatts per hour.
1 kilowatt per hour (KWh) = 1000 watts
iii) Since you have determined the energy your microwave consumes in one hour, you need to multiply this figure by the time it has run. This gives you the total amount of energy consumed that day.
iv) To determine how much it costs to run a microwave, multiply the energy consumed by the cost of usage per KWh. This cost varies from one state to another.
Energy cost of running your microwave = (kilowatts/hour) x (time running) x (Cost ($) per kilowatt-hour)
v) If you want to save costs by lowering your electric bills, purchase an energy-efficient microwave. The market is currently offering the best energy-efficient microwaves at different price points. Just choose one that fits your needs and is pocket-friendly.
Factors that Influence the Energy Consumption of Microwaves

Microwave ovens have become important appliances in our homes. They help us save time because they heat and cook food quickly even though their energy consumption is quite high. The following factors determine a microwave’s energy usage:
1. The Size of the Microwave
One of the main criteria when selecting a microwave oven is the size. A large microwave uses more electricity than a smaller one. This is because more energy is utilized to heat up a larger space. Smaller microwaves are also great for people who do not have a lot of kitchen space.
2. The Usage of the Microwave
How you use your microwave determines how much electricity bill you will pay at the end of the month. If you use the appliance for longer, electricity usage goes up. Thus, if you do not use the gadget frequently, it would be best to buy a low-wattage microwave. However, large models are recommended for bigger families.
3. Microwave Wattage
A microwave oven may be low-wattage or high-wattage. The higher the wattage, the more powerful the gadget. If your goal is to save on energy, you can purchase a microwave with low-wattage. However, the one with higher wattage may heat up food more quickly and save time.
4. The Type of Food
Different foods take dissimilar amounts of heat to cook. For example, food such as meat would take longer to heat than vegetables or cereals. The longer it takes for food to heat up or cook, the higher the microwave energy consumption.
5. Age
A microwave oven is not meant to last forever. Most of them have a lifespan of ten years. The older the microwave gets, the more energy it uses. The magnetron that is responsible for transforming electrical energy to microwave energy has lost its strength over the years. Thus, what would take 25 seconds to heat up today would take 50 seconds in the next seven to ten years.
6. Maintenance
A gadget is always as good as how well it is maintained. It can serve you longer if it is properly maintained. A microwave is no different. Correct cleaning and upkeep can enhance its energy efficiency. A properly cleaned appliance reflects microwave energy better. Hence, saving more energy.
7. Standby Power Consumption
Every electrical appliance has a small power consumption when on standby mode. This is the power that is utilized by electrical devices when they are off but plugged in. When in standby mode, a microwave’s wattage is between 2 and 7. Different microwave models have dissimilar standby power consumption. It is advisable to check before purchasing.
8. Microwave Models
The kitchen gadget world offers a variety of microwave ovens. The design of your appliance and the material used to manufacture it determine the amount of energy it consumes. There are models that are energy star appliances. These ones are energy-efficient microwaves. Always check the energy star rating on microwaves before making a purchase.
Frequently Asked Questions on Microwaves’ Wattage

1. Does Using a Microwave Use a Lot of Electricity?
Yes. A microwave can use a lot of electricity. The total amount of energy consumed by your microwave will depend on the amount of time it is in use. Most microwaves are used for a few minutes a day. Well, this is with the exception of commercial microwaves that are used for a couple of hours a day.
2. How Much Does It Cost To Run a Microwave For 1 Hour?
The cost to run a microwave is dependent on a number of factors such as the size, type of food, and model just to name a few. On average, it may cost you $0.15 per hour to operate a compact microwave and $0.21 per hour to run a standard one. However, you can spend up to $0.44 per hour to run powerful microwaves. Even so, the amount you pay at the end of the day will depend on the power rating in your area.
3. How Many Solar Panels Will Power My Microwave?
You can use solar energy to power your microwave. A standard microwave uses about 800 watts, meaning three or four solar panels of 350 watts each could power it. The fact that you use the microwave for only a few minutes a day helps you save money.
4. How Much Electricity Does a 1000 Watts Microwave Use?
Most microwave recipes call for a gadget that uses between 700 and 1000 watts. Even though the wattage level may seem like a lot, these microwaves do not use up a lot of electricity. Energy consumption will greatly depend on the length of time that the gadget is in use. On average, a 1000 watts microwave consumes 91.3 kWh per year.
5. Can a Solar Generator Run a Microwave?
Yes. Solar generators can run a microwave because they produce above 1,000 watts. Nevertheless, you must be careful when using a solar generator so the appliance is not damaged. For this reason, the solar generator should be reliable and provide power consistently.
