Do slow cookers use a lot of electricity

Do slow cookers use a lot of electricity. Slow cookers, also known as crockpots, have been a staple in kitchens for decades.

They are a convenient and efficient way to prepare meals, especially for busy individuals who don’t have a lot of time to spend cooking.

However, many people wonder whether slow cookers use a lot of electricity and if they are an energy-efficient option.

The answer to this question is not straightforward, as it depends on various factors, such as the size of the slow cooker, cooking time, and temperature settings.

In this article, we will delve into the world of slow cookers and examine their energy usage to determine if they are an electricity guzzler or an energy-saving kitchen appliance.

Slow cookers are designed to be energy-efficient, using only a fraction of the energy compared to a traditional oven or stovetop.

According to the US Department of Energy, slow cookers use between 100 and 250 watts of electricity on low heat, and between 150 and 300 watts on high heat. This is equivalent to using a 60-watt light bulb for an extended period.

Compared to a traditional oven, which uses between 2,000 and 5,000 watts of electricity, and a stovetop, which uses between 1,000 and 3,000 watts of electricity, slow cookers are incredibly energy-efficient.

This makes them an excellent option for those looking to reduce their energy consumption and save money on their utility bills.

How Does a Slow Cooker Work

A slow cooker works by using a combination of low heat and moisture to cook food slowly over several hours. The heating element in the slow cooker produces a low, steady heat that is transferred to the cooking pot.

This heat is then distributed evenly throughout the pot, cooking the food inside. The lid traps the steam and moisture, creating a moist cooking environment that helps to retain the flavors and nutrients of the food.

Tips for Using Your Slow Cooker Efficiently

While slow cookers are already energy-efficient, there are several tips you can follow to make them even more so.

1. Use the Right Size Slow Cooker for the Job

Using a slow cooker that is too large for the meal you are preparing can lead to energy waste. The slow cooker will take longer to heat up, and more energy will be needed to maintain the temperature inside the pot.

Conversely, using a slow cooker that is too small for the meal may lead to overfilling the pot, which can cause the food to cook unevenly or spill over.

To ensure energy efficiency, choose a slow cooker that is the right size for the meal you are preparing. This will help to ensure that the cooking time is reduced, and the energy used is minimized.

2. Preheat the Slow Cooker

Preheating the slow cooker is an excellent way to reduce the cooking time and save energy.

By preheating the pot, you are ensuring that it is already hot when you add the ingredients, which means it will take less time to heat up and cook the food.

To preheat the slow cooker, turn it on to the desired temperature, and let it heat up for 20 to 30 minutes before adding the ingredients. This will help to reduce the cooking time and save energy.

3. Use the Low Setting When Possible

Slow cookers have two temperature settings, low and high. Using the low setting whenever possible can help to save energy. The low setting uses less electricity and is perfect for foods that need to be cooked slowly over a more extended period.

4. Avoid Lifting the Lid

Lifting the lid of the slow cooker during the cooking process can cause the heat to escape, leading to a longer cooking time and increased energy consumption.

While it may be tempting to check on the food, try to resist the urge to lift the lid. Instead, trust the cooking process and let the slow cooker do its job.

5. Use the Right Amount of Liquid

Using too much liquid in the slow cooker can lead to excess steam and moisture, which can increase the cooking time and energy consumption.

On the other hand, using too little liquid can cause the food to dry out and burn, leading to a wasted meal.

To ensure energy efficiency, use the right amount of liquid for the meal you are preparing. This will help to create the right amount of steam and moisture, reducing the cooking time and energy consumption.

6. Plan Your Meals Ahead of Time

Planning your meals ahead of time can help you to use your slow cooker more efficiently. By planning ahead, you can ensure that you are using the right size slow cooker for the meal, using the low setting whenever possible, and preheating the pot to reduce cooking time and energy consumption.

Additionally, planning ahead can help you to use up ingredients that may be close to their expiration date, reducing food waste and saving money on your grocery bill.


Can using a slow cooker help save money on electricity bills?

Yes, using a slow cooker can help reduce your energy consumption and save money on your electricity bills, especially if you use it as a substitute for oven or stovetop cooking.

However, it’s worth noting that the overall impact on your electricity bills will depend on a variety of factors, including the size and efficiency of your slow cooker, how often you use it, and your local energy rates.

Is it expensive to use a slow cooker?

No, it is not expensive to use a slow cooker. Even if you use it for several hours at a time, the electricity cost is generally very low.

In fact, slow cookers are often used specifically because they are an affordable way to cook food without using a lot of energy.

Can a slow cooker save energy compared to other cooking methods?

Yes, a slow cooker can save energy compared to other cooking methods. Because it uses low heat over a long period of time, it uses less energy than an oven or stovetop, which require higher heat for shorter periods of time.

Additionally, slow cookers are often used to cook large batches of food, which can be more energy-efficient than cooking multiple smaller batches on the stovetop or in the oven.


Slow cookers are a convenient and energy-efficient way to prepare delicious meals without using excessive amounts of electricity. While they may use more electricity than some other cooking methods, their extended cooking time means that they are still relatively energy-efficient in the long run. Additionally, many modern slow cookers are designed with energy-saving features, such as programmable timers and automatic shut-off functions. Ultimately, whether a slow cooker uses a lot of electricity depends on how it is used and how frequently it is used. By using it wisely and choosing a model with energy-saving features, you can enjoy the convenience of slow cooking while minimizing your energy usage.
