According to the U.S. Energy Information Administration, a conventional electric oven uses around 2.3 kilowatt-hours (kWh) of electricity per hour. In contrast, a slow cooker uses around 0.2-0.5 kWh of electricity per hour.
- Stovetop Cooking: Stovetop cooking is another common method that requires a significant amount of energy. Electric stoves use around 1.2-2.4 kWh of electricity per hour, while gas stoves use around 0.4-0.8 kWh of electricity per hour (not including the energy required to produce and transport the gas).
- Microwave Cooking: Microwaves are generally more energy-efficient than ovens and stovetops. They use around 0.6-1.2 kWh of electricity per hour. However, microwaves cook food quickly, so the overall energy consumption is often lower than slow cookers.
Energy Consumption of Slow Cookers
The energy consumption of slow cookers varies depending on the size and type of cooker. Here are some approximate energy consumption values for different slow cooker sizes:
| Slow Cooker Size | Energy Consumption (kWh/h) |
| — | — |
| Small (1.5-2 quarts) | 0.2-0.3 |
| Medium (3-4 quarts) | 0.3-0.5 |
| Large (5-6 quarts) | 0.5-0.7 |
| Extra Large (7-8 quarts) | 0.7-1.0 |
As you can see, slow cookers are generally more energy-efficient than ovens and stovetops. However, their energy consumption can add up over time, especially if you use them frequently.
Factors Affecting Slow Cooker Energy Efficiency
Several factors can affect the energy efficiency of slow cookers. Here are some of the most significant ones:
- Size: Larger slow cookers tend to consume more energy than smaller ones. However, they can also cook more food at once, which can be more energy-efficient in the long run.
