| Keep Warm | 30 – 70 | 0.03 – 0.07 |
For example, using a slow cooker on the low setting at 100 watts for 8 hours would consume approximately 0.8 kWh of electricity, which is relatively low compared to many other cooking methods.
Factors Affecting Overall Energy Consumption
While wattage gives a snapshot of power usage, overall energy consumption depends on how long the slow cooker runs and the specific cooking program.
- Cooking Duration: Slow cookers are designed to cook meals over several hours, often between 4 to 10 hours or more. Longer cooking times increase total energy use but still typically consume less energy than oven cooking.
- Food Quantity and Temperature: Larger amounts of food require more energy to heat. Additionally, starting with ingredients at room temperature reduces energy use compared to adding cold or frozen items.
- Model Efficiency: Newer models may use advanced insulation and heating technology, leading to more efficient energy use.
- User Practices: Using the lid consistently and avoiding frequent opening helps retain heat and reduces power needed to maintain temperature.
Comparing Slow Cooker Energy Use with Other Appliances
When evaluating the efficiency of slow cookers, it’s helpful to compare their energy consumption with other common kitchen appliances.
| Appliance | Typical Wattage | Energy Use per Hour (kWh) | Cooking Method |
|---|---|---|---|
| Slow Cooker (Low Setting) | 70 – 150 W | 0.07 – 0.15 | Slow, prolonged heat |
| Electric Oven | 2000 – 5000 W | 2.0 – 5.0 | High heat, shorter time |
| Microwave Oven | 600 – 1200 W | 0.6 – 1.2 | Fast, high heat |
